Abstract (sommario):

The predicted future operating room nurse and surgical technologist shortages may have significant implications for the healthcare industry. Improving the job satisfaction of operating room personnel could promote retention and provide adequate staffing in operating rooms. The job satisfaction of operating room nurses and surgical technologists can result in positive or negative work environments. The purpose of the qualitative phenomenological study was to explore the perceptions of job satisfaction of operating room nurses and surgical technologists to discover how job satisfaction influences the intent to leave or remain in the work environment of the operating room. A purposive selection was made of 12 registered nurses and 12 surgical technologists who had varying degrees of experience in the healthcare field, and were working part time or full time in the operating room of a pediatric medical center in North, Texas. Interviews were audio-recorded and the seven steps were used from Moustakas van Kaam analysis to reveal themes and patterns from the research data. Six themes emerged from the research study that included teamwork, recognition from surgeon, working with pediatric patients and their families, staff appreciation, work environment, and executive leadership. Based on the findings, further research is needed to ascertain strategies that would improve operating room registered nurses and surgical technologists’ job satisfaction and retention.

Massachusetts General Hospital (MGH) is ranked as the top hospital in New England and second nation-wide. It is also the largest hospital in New England; it uses an average of 58 operating rooms, where approximately 150 surgical procedures are performed daily. Management of surgical supplies is a critical component of the processes supporting this infrastructure. Specifically, ensuring the right equipment and supplies are available at the right time is critical for the efficiency and quality outcomes of each of the procedures. The materials management group handles over 10,000 unique items, purchased from more than 400 vendors. The majority (60-70%) of disposable supplies are ordered through Owens & Minor, a medical and surgical supplies distributor. The supplies are stored in multiple locations throughout the hospital, including two central locations as well as carts and cabinets on the surgical floors and in the operating rooms. The work described in this thesis focuses on the inventory management of disposable surgical supplies, where the current system design has inefficiencies in the inventory levels and location of items. Using a data-driven approach, based on historical demand, we calculate base stock levels by item that maintain three days of inventory at a 99 percent service level. In addition, we suggest a methodology to support decisions on inventory locations of the different items. Implementation of the recommended changes is estimated to result in savings of 30-40% in inventory levels (and space), corresponding to a one time saving of $700,000-$900,000, depending on the implementation scenario. In addition, the reduction in inventory levels can be translated to future savings in inventory holding costs at an estimated 40% rate, leading to a saving of roughly $300,000 annually.

ENGLISH ABSTRACT: Given the increase in the cost of health care, economic considerations have drawn more and more interest over the last decade. Facilities are faced with the challenge to reduce costs while maintaining productivity. The Operating Room (OR) represents a significant opportunity to reduce expenses and improve efficiency. With the development of ambulatory or day surgery, minimally invasive procedures and the decline in admissions to hospitals the management of the OR suite needs re-evaluation. The Battlefords Union Hospital has a four room OR suite that performs a mixture of both inhospital and day surgeries. The current OR suite efficiency is determined by its adherence to the annual budget. A literature study was conducted with the focus on OR efficiency and in particular Patient Outcome and OR Management. Other issues included Perioperative Information systems and OR design. A survey was conducted in the OR suite and responses obtained from OR staff were evaluated. The survey included questions on patient experiences, procedural times, case scheduling, support, communication, quality measures and OR efficiency. The goals of this project was not to do an extensive statistical analysis of OR data. A limited study of OR suite data was presented to highlight relevant OR efficiency indicators. A summary of the findings and recommendations for improvement of the Battlefords Union Hospital OR suite’s efficiency, concludes the report.
AFIKAANSE OPSOMMING: Na aanleiding van die verhoging in koste van gesondheidsorg die laaste dekade, is ekonomiese aspekte meer op die voorgrond. Inrigtings word deur uitdagings in die gesig gestaar om kostes te verminder, terwyl produktiwiteit gehandhaaf moet word. Die operasie suite bied ‘n aansienlike geleentheid om kostes te verminder en effektiwiteit te verhoog. Met die ontwikkeling van dagchirurgie, “minimal invasive” prosedures en die afname in hospitaal opnames, behoort die bestuur van operasie suites herevalueer te word. Die Battlefords Union Hospitaal het ‘n vier teater operasie suite waar ‘n verskeidenheid van dagchirurgie en in-hospitaal prosedures uitgevoer word. Die operasie suite se effektiwiteit word huidiglik slegs gemeet aan die mate van hoe dit binne die jaarlikse begroting bly. ‘n Literatuurstudie is uitgevoer met die fokus op operasie suite effektiwiteit, met die klem op pasient uitkoms en operasie suite bestuur. Ander items wat ook ondersoek is, sluit in perioperatiewe informasie stelsels en teater ontwerp. ‘n Empiriese studie, gebaseer op ‘n vraelys, is uitgevoer onder die staflede van die operasie suite by die Battlefords Union Hopitaal. Die vraelys het vrae ingesluit oor pasient ervarings, prosedure tye, geval skedulering, kommunikasie, kwaliteitsversekering en operasie suite effektiwiteit. Die doel van die projek was nie om ‘n uitgebreide statistiese analise van die operasie suite data te doen nie. 'n Beperkte studie van die beskikbare data is gedoen en relevante effektiwiteits indikators is uitgewys. Die verslag word afgeëindig deur bevindinge, gevolgtrekkings en aanbevelings oor hoe die Battlefords Union Hospitaal die operasie suite se effektiwiteit moontlik kan verhoog.

Abstract (sommario):

Organizational work climates in healthcare organizations were described in the literature using a social framework of structured interactions, defined roles, and behavioral responses between team members of physicians and nurses. It was hypothesized that the characteristics of physician-nurse collaboration, physician dominance, and nurse autonomy in socially complex work settings have relationships to turnover intent in nurses who work in operating room settings. In an era of nursing shortages the challenge of nurse retention and the evidence of challenging work climate become even more critical for healthcare organizations. This research study examined a gap in knowledge regarding the extent to which aspects of organizational work climate predict nurse turnover in operating room work settings. A quantitative correlational study using three work climate characteristics of physician-nurse collaboration, physician dominance, and nurse autonomy was conducted using the Jefferson Scale of Attitudes Toward Physician-Nurse Collaboration (Hojat & Herman, 1985, Developing an Instrument to Measure Attitudes toward Nurses: Preliminary Psychometric Findings) and the Anticipated Turnover Scale (Hinshaw & Atwood, 1983, Nursing Staff Turnover, Stress, and Satisfaction: Models, Measures, and Management). Responses from 322 Operating Room staff nurses who were members of a national professional nursing organization were examined in the analyses. The study concluded that the independent variables of collaboration, dominance, and autonomy were not significant in predicting turnover among nurses in the operating room setting.

In the current healthcare environment, the cost of delivering patient care is an important concern for hospitals. As a result, healthcare organizations are being driven to maximize their existing resources, both in terms of infrastructure and human capital. Using a data-driven approach with analytical techniques from operations management can contribute towards this goal. More specifically, this thesis shows, drawing from a recent project at Beth Israel Deaconess Medical Center (BIDMC), that predictive modeling can be applied to operating room (OR) scheduling in order to effectively increase capacity. By examining the current usage of the existing block schedule system at BIDMC and developing a linear regression model, OR time that is expected to go unused can be instead identified in advance and freed for use. Sample model results show that it is expected to be operationally effective by capturing a large enough portion of OR time for a pooled set of blocks to be useful for advanced scheduling purposes. This analytically determined free time represents an improvement in how the current block system is employed, especially in terms of the nominal block release time. This thesis makes the argument that such a model can integrate into a scheduling system with more efficient and flexible processes, ultimately resulting in more effective usage of existing resources.

Abstract (sommario):

Balancing trade-offs between production cost and holding cost is critical for production and operations management. Utilization of an operating room affects production cost, which relates to makespan, and patient flowtime affects holding cost. There are trade-offs between two objectives, to minimize makespan and to minimize flowtime. However, most existing constructive heuristics focus only on single-objective optimization. In the current literature, NEH is the best constructive heuristic to minimize makespan, and LR heuristic is the best to minimize flowtime. In this thesis, we propose a current and future deviation (CFD) heuristic to balance trade-offs between makespan and flowtime minimizations. Based on 5400 randomly generated instances and 120 instances in Taillard’s benchmarks, our CFD heuristic outperforms NEH and LR heuristics on trade-off balancing, and achieves the most stable performances from the perspective of statistical process control.

Abstract (sommario):

Operating room performance is becoming more and more important for the hospital’s finance and the patient’s well-being. Thus, hospitals need to develop dashboards that can assess the actual performance of its core service, to be able to decide how to improve it. The point of this thesis is to build a common audit tool which can be used in regular hospitals. To build so, a literature review has been made, gathering all the relevant organizational and performance indicators. Since only a few of them need to be selected, a group of experts has been gathered via the Delphi method to decide which indicators to keep and which ones to reject, for the implementation in the tool. Out of forty-two indicators found in the literature, only fifteen will be considered and implemented into graphs. These graphs will form the preliminary audit from which hospital and consultants can base their performance assessment of the operating room, by pinpointing what their analysis should focus on. This tool has been tested in a real hospital to identify a few improvements that the tool requires and the few technical mistakes the tool possessed. The tool can save time for the consultants and for the hospital. Saving time in the healthcare sector ultimately means having more time for the patients, which, in the end, enhances their experience and well-being. It allows some flexibility as well and can be adapted even more to the needs of the studied hospitals. Moreover, compared to simple dashboards, this tool will give more useful indicators and help hospital’s management to take some decisions and reconsider others - again, for the best outcome for the patients
Operationssalens prestation blir mer och mer viktig för sjukhusets ekonomi och patienternas välmående. Därför behöver sjukhusen utveckla instrumentbrädor som kan utvärdera hur denna huvudtjänst presterar, för att sedan kunna bestämma hur man bäst förbättrar den. För att skapa ett sådant hjälpmedel har en litteraturöversikt gjorts för att samla alla relevanta indikatorer från organisationen och dess prestationer. Eftersom endast en bråkdel av dessa behövs så har en grupp med experter sållats ut genom Delphi-metoden; denna bestämde vilka indikatorer som borde behållas respektive avslås, för implementering i hjälpmedlet. Av fyrtiotvå indikatorer kommer endast femton att övervägas och implementeras i grafer. Dessa grafer kommer att skapa den preliminära revision från vilken sjukhus och konsulter kan basera sin prestationsutvärdering av operationssalarna; hjälpmedlet sätter fingret på vad analysen bör fokusera på. Detta hjälpmedel har prövats i ett riktigt sjukhus för att identifiera ett fåtal nödvändiga förbättringar, samt de få tekniska problem som hjälpmedlet hade. Detta hjälpmedel kan spara tid för sjukhus och konsulter. Visserligen skulle man kunna skapa en egen instrumentbräda, noga anpassad till det studerade sjukhuset, men då lär hjälpmedlet inte kunna användas i andra kontexter; man kan också använda ett mer komplext men detaljerat hjälpmedel, men detta kräver mer tid för att förstå hur den bör användas. I sjukvården innebär sparad tid att mer tid kan läggas på patienterna, vilket i slutändan förbättrar deras upplevelser och välmående. Dessutom kommer detta hjälpmedel, i jämförelse med enkla instrumentbrädor, att bidra med mer användbara indikatorer och hjälpa sjukhusets ledning att ta somliga beslut och omvärdera andra – än en gång för patienternas bästa.

Abstract (sommario):

Improved utilization of scarce resources such as health care personnel is necessary to address well-known problem of long waiting times within the health care. Implementing mathematically modeled scheduling in the operating theatre has the potential to result in more efficient allocation of resources and financial gains. Despite the promising results, the adoption rate of such models is low. This thesis examines the impact of a mixed-integer linear programming model using an overlapping strategy. We perform a computational experiment where both sequential and parallel schedules are produced with real surgery data from an orthopedic department at a Swedish university hospital. The generated schedules are compared against each other in measurements of cost productivity. Statistical analysis shows that there is a statistical significant difference between the two schedules, favoring the optimized schedule. The results further suggest that three operating rooms and four surgery teams is the most optimal combination of the 18 combinations analyzed, where operating rooms and surgery teams varies between 1-4 and 1-6, respectively.

Abstract (sommario):

Avec l'augmentation de la demande de soins dans le monde, les services hospitaliers sont de plus en plus sollicités. Leur performance est étroitement liée à la performance de leur bloc opératoire. En effet, le bloc opératoire est un important centre de revenus et de dépenses puisqu'il représente 40% du budget de l'hôpital (Macario et al. 1997), et que 60% des patients viennent à l'hôpital pour une intervention chirurgicale (Fugener et al. 2017). Il est donc nécessaire que les blocs opératoires soient efficients. Cependant, cela est rendu difficile par la complexité de leur organisation due à la diversité des parcours patients, la multiplicité des métiers, les liens étroits avec les services amont et aval, la synchronisation de plusieurs ressources et flux logistiques (personnels, médicaments et dispositifs médicaux), etc. D'autre part, la variabilité des durées et les perturbations inhérentes à la pratique médicale, comme les cas d'urgence, sont les principaux facteurs et événements qui dégradent le programme opératoire et impliquent que le personnel prenne de fréquentes décisions pour maintenir l'activité du bloc opératoire de manière optimale. Par conséquent, les activités de planification et d'ordonnancement du bloc opératoire intéressent de plus en plus la communauté scientifique. Dans cette thèse de doctorat, nous nous concentrons sur les niveaux opérationnels hors ligne et en ligne (Hans et Vanberkel 2012). Ceci nous amène aux questions de recherche suivantes : (1) Comment évaluer la robustesse et la résilience du programme opératoire avant son exécution (dimension prospective) ? (2) Comment rejouer le programme opératoire pour avoir un retour d'expérience et évaluer les décisions prises lors de son exécution (dimension rétrospective) ? La contribution de ce manuscrit est triple : (1) Nous proposons un système d'aide à la décision basé sur un jumeau numérique pour la simulation et l'analyse prospectives et rétrospectives de l'exécution du programme opératoire. (2) Nous décrivons une méthodologie standardisée pour concevoir, construire et mettre en œuvre cet outil dans n'importe quel bloc opératoire. (3) Cette méthodologie est appliquée à un bloc opératoire inspiré de l'Hôpital Privé de La Baie (groupe Vivalto Santé), afin de disposer d'une preuve de concept permettant de simuler un programme opératoire de façon prospective et rétrospective
With healthcare demand rising worldwide, hospital services are increasingly needed. Hospitals' performance is tightly linked to their surgical suite performance. Indeed, the surgical suite is an important revenue and expense center with over 40% of the hospital's budget dedicated to it (Macario et al. 1997) and 60% of the patient coming into the hospital for surgical intervention (Fugener et al. 2017). This makes it necessary for surgical suites to be efficient. However, running a profitable surgical suite is quite hard and requires a methodological approach due to the complexity of its functioning: the diversity of patient pathways, the multiplicity of professions, the tight link with upstream and downstream wards, the synchronization of several resources and logistic flows (drug and medical devices), etc. On the other hand, durations variability and disruptions inherent in medical care like emergency cases are the main factors and events that degrade the scheduled execution and involve the staff making decisions frequently to preserve the surgical suite activity in an optimal way. Therefore, OR planning and scheduling activities are of increasing interest to the scientific community. In this PhD thesis, we focus on offline operational and online operational levels (Hans and Vanberkel 2012). This leads us to the following research questions: (1) How can we assess the robustness and the resilience of the schedule before its execution (prospective way)? (2) How can we replay the schedule to have feedback and assess the decisions made during its execution (retrospective way)? The contribution of this manuscript is threefold: (1) we propose a digital twin-based decision support system for the prospective and retrospective simulation and analysis of the operating room schedule execution, (2) we describe a standardized methodology to conceive, build and implement this tool in any surgical suite, (3) This methodology is applied to an operating room inspired by the Private Hospital of La Baie (Vivalto Santé group, France), in order to have a proof of concept allowing to simulate an operating program prospectively and retrospectively

Abstract (sommario):

O estudo do dimensionamento de pessoal de enfermagem em Centro Cirúrgico (CC), foi realizado segundo o movimento anual de cirurgias, com os objetivos de: calcular a capacidade anual de horas de enfermagem no C.C.; identificar as horas de assistência de enfermagem em C.C. por categoria profissional e associar a capacidade de horas de enfermagem anual e por categoria profissional com o tempo de utilização de C.C. Foi desenvolvido em um Hospital Universitário, geral, voltado para assistência secundária, no minicípio de São Paulo. O C.C. desenvolve a Sistemática da Assistência de Enfermagem Perioperatória (SAEP), para o cuidado sistematizado e individualizado ao paciente cirúrgico, com visita pré-operatória prestada ao paciente pelo enfermeiro e auxiliar de enfermagem; assistência no pós-operatório imediato na RA e transporte do paciente até a sua unidade de destino. A assistência indireta ao paciente também é realizada, como os cuidados com o ambiente, administração de recursos materiais e humanos. Os dados foram obtidos por meio de entrevista com a enfermeira-chefe do C.C., levantamento dos registros do movimento cirúrgico, escalas de pessoal e fichas com dados das ausências previstas e não previstas do pessoal de enfermagem. A análise foi desenvolvida em quatro etapas: identificação da capacidade cirúrgica segundo o movimento anual das cirurgias; identificação da capacidade cirúrgica segundo o movimento anual das cirurgias; identificação da capacidade anual de horas de enfermagem no C.C.; associação das horas de assistência de enfermagem por categoria profissional e capacidade cirúrgica. Os resultados possibilitaram as seguintes identificações: a capacidade cirúrgica, é caracterizada pela capacidade estrutural de 87.600 horas, capacidade operacional de 33.627,22 horas e capacidade de utilização de 12.246,95 horas; a capacidade anual das horas de enfermagem é 35.749,03 horas; as horas de assistência de enfermagem na categoria enfermeiro 1,69 horas por paciente e na categoria de auxiliar de enfermagem com 6,95 horas por paciente. O percentual de ausências foi de 39,72%, para um movimento cirúrgico em dias úteis de 2.711 cirurgias, obteve-se uma média de 10.839,53 horas de utilização de C.C., com 18.814,45 horas de assistência de enfermagem para categoria auxiliar de enfermagem. Este estudo tem por finalidade contribuir para a composição do quadro de pessoal de enfermagem, mais próximo à realidade, evitando sobrecargas dos trabalhadores ou períodos de ociosidade
The proposal of this study is to verify the need of nursing staff in Operating Romm Department, to identify the utilization time of Operating Rooms (OR) through annual surgeries number; to calculate annual number of nursing staff in OR; to identify number of hours of nursing care in OR done by each professional categories and to associate number of hours of nursing by each professional category with OR utilization time. This research was done in University Hospital which is general and provide secondary assistence in São Paulo City. The OR used Perioperative Nursing System to systematize and individualized nursing care to surgical patient. The system components are: pre and post operative visits realized by OR registered nurse; intraoperative nursing care by Registered nurse and ancillary nurse; immediate post-operative nursing care and transport of patient to specific unit. Other activities that are realized by nursing staff are: preparatio and cleaness of OR, management of material and human resources in order to improve the nursing interview with OR head-nurse and analysing records of surgeries, nursing staff schedute and absenteism. The data was analysed in four fases: identification of surgical capacity in relation of annual number of surgeries; identification of number of nursing care hour per each professional category and association of surgical capacity with number of surgeries that would be done. The results showed these conclusions: number of surgeries was 87.000 hours in structural capacity; 33,627.22 hours in operational capacity and 12,246.22 in utilization capacity. The annual nursing capacity is 35,749.03 hours; the number of hours by Registered nurse is 1.69 hours each patient; to the ancillary nurse is 6.95 hours each patient. The absenteism rate was 39.72%. Analysing the number of surgeries realized in week days is 2,711 surgeries with 10,893.53 hours in average of OR utilization; 4,518.59 hours of Registered nurse care and 18,893.53 hours in average of ancillary nurse care. The goal of this study is to analyse the number of nursing staff in OR through comparation of surgical capacity and nursing care hours

RESUMO - A consciência de uma necessidade clara em rentabilizar a capacidade instalada e os meios tecnológicos e humanos disponíveis no Bloco Operatório e face ao imperativo de um cabal desempenho e de uma adequada efectividade nestes serviços levou-nos à realização deste estudo. Objectivos: O trabalho de projecto centrou-se em quatro objectivos concretos: Elaboração de uma grelha de observação de Modelos de Gestão de Bloco Operatório; Observação de seis Modelos de Gestão de Blocos Operatórios em experiências nacionais e in-loco, de acordo com a grelha de observação; Avaliação da qualidade gestionária na amostra seleccionada à luz dos modelos existentes; Criação de uma grelha de indicadores para a monitorização e avaliação do Bloco Operatório. Metodologia: Na elaboração da grelha de observação dos Blocos Operatórios recorremos a um grupo de peritos, à bibliografia disponível e à informação recolhida em entrevistas. Aplicámos a grelha de observação aos seis Blocos Operatórios e analisámos as informações referentes a cada modelo com a finalidade de encontrar os pontos-chave que mais se destacavam em cada um deles. Para a elaboração da grelha de indicadores de monitorização do Bloco Operatório realizámos uma reunião recorrendo à técnica de grupo nominal para encontrar o nível de consenso entre os peritos. Resultados: Criámos uma grelha de observação de Modelos de Gestão de Bloco Operatório que permite comparar as características de gestão. Esta grelha foi aplicada a seis Blocos Operatórios o que permitiu destacar como elementos principais e de diferenciação: o sistema de incentivos implementado; o sistema informático, de comunicação entre os serviços e de débito directo dos gastos; a existência de uma equipa de gestão de Bloco Operatório e de Gestão de Risco; a importância de um planeamento cirúrgico semanal e da existência de um regulamento do Bloco Operatório. Desenhámos um painel de indicadores para uma monitorização do Bloco Operatório, de onde destacamos: tempo médio de paragem por razões técnicas, tempo médio de paragem por razões operacionais, tempo médio por equipa e tempo médio por procedimento. Considerações finais: Os Blocos Operatórios devem ponderar a existência das componentes mais importantes dos Modelos, bem como recolher exaustivamente indicadores de monitorização. A investigação futura deverá debruçar-se sobre a relação entre os indicadores de monitorização e os Modelos de Gestão, recorrendo à técnicas de benchmarking. -------------------ABSTRACT - This study was driven by the need to optimise available capacity, technology and human resources in the Operating Room and to address the corresponding goals of adequate performance and effectiveness. Objectives: This project focuses on four specific objectives: development of an observation grid of operating room management models; in-loco observation and documentation of six national operating room, according to the grid; assess the quality of management in the selected sample relative to existing management models; create a set of indicators for monitoring and evaluating operating rooms. Methodology: The design of the observation grid was based on experts’ consultation, a literature survey and information gathered in various interviews. The observation grid was applied to six operating rooms and the information for each management model was analysed in order to find its key characteristics. We used the Nominal Group Technique in order to develop a set of indicators for monitoring and evaluating operating rooms. Results: An observation grid was created for operating rooms management models, which allowed comparing management characteristics. This grid was applied to six operating rooms allowing disentangle its main features and differentiating characteristics: implementation of incentive systems; IT systems including information flow between services; inventory and expense management; existence of a management team and effective risk management; importance of weekly planning and regulations. We designed a set control indicators, whose major characteristics are the following: the average down time due to technical reasons, the average down time due to operational reasons, the average time per team and the average time per procedure. Final Conclusions: Operating rooms should consider the most relevant characteristics of management models and collect exhaustive information on control indicators. Future research should be devoted to assessing the operating room performance according to management models, using control indicators and benchmarking techniques.

Abstract (sommario):

Negli ultimi anni si sta assistendo sempre di più all’avvicinamento dell’ingegneria gestionale all’ambito sanitario. La sanità è un mondo complesso che offre molte opportunità di miglioramento. Un esempio di questo connubio è la realizzazione di un modello matematico in grado di stabilire la pianificazione mensile delle sale operatorie di un ospedale in base alla lista d’attesa. Un simile strumento può risultare molto utile in ambito decisionale per la riduzione dei tempi d’attesa dei pazienti. Si è partiti da un modello matematico sviluppato in tesi precedenti che tiene in considerazione una serie di risorse fisiche, umane e temporali, ma che non considera una risorsa fisica molto importante: il posto letto per la degenza del paziente. L’obiettivo principale di questo elaborato è quello di estendere il modello matematico in modo tale che possa considerare anche il numero di posti letto a disposizione per ciascuna specialità chirurgica dell’ospedale. L’obiettivo secondario è l’applicazione del modello al caso reale di un importante ospedale bolognese. Nel capitolo 1 si descrive in breve il funzionamento del SSN, il modo in cui il problema della gestione delle sale operatorie è stato suddiviso e il percorso clinico del paziente. Nel capitolo 2 viene descritto in dettaglio il modello matematico originale, il database reso disponibile da un ospedale romagnolo e il software utilizzato per la risoluzione del modello.

Abstract (sommario):

In questa tesi è stato analizzato e tradotto nel linguaggio di alto livello AMPL un modello di ILP relativo alla pianificazione tattica del blocco operatorio. L'obiettivo è quello di permettere l'interfacciamento con numerosi solver -commerciali e non- al fine di analizzarne le prestazioni. In seguito a un'introduzione in merito al problema dell'Operating Room Management e a una descrizione del contesto sanitario regionale dell'Emilia-Romagna, si è proceduto alla descrizione formale del modello. Infine sono state eseguite numerose risoluzioni con i solver cplex e gurobi al variare di alcuni parametri in ingresso, tra cui il numero di sale operatorie, di infermieri e operatori sanitari, e di pazienti in lista d'attesa.

Abstract (sommario):

Inom hälso- och sjukvårdsområdet såväl som inom många andra yrkesområden förs idag en diskussion om säkerhet och hur denna kan upprätthållas. Anestesisjukvården är inget undantag. Den största delen av debatten ligger på en lednings eller chefsnivå, där man pratar om hela system som måste omarbetas för att finna en säkrare miljö för patienter och yrkesverksamma. Syftet med denna studie var att belysa och beskriva de metoder som de kliniskt verksamma inom anestesisjukvården kan använda sig av för att ge en så säker vård som möjligt till patienten i samband med anestesi. Metoden var en litteraturstudie som bygger på tio vetenskapliga artiklar. Resultatet visade att de fem metoder som används är incidensrapportering, checklistor, teamträning, fortbildning med och utan simulatorer samt utökat användande av videoteknik. Det visade sig att dessa metoder inte är nya. Samma metoder finns beskrivna i litteraturen sedan 1970-talet men de har vidareutvecklats.
In health care as well as in many other professions today there are a debate going on about safety management and preventive safety work. The anaesthesia department is no exception.The main discussion is on the level of leadership, and it is about how to change whole systems so the environment around the patient and the professional work will be safer. The purpose of this literature review was to elucidate and describe the methods the anaesthetisa workers can use to give the patient as safe anaetsthesia care as possible. Our method was a literature review based on ten scientific articles. The result showed five different methods, incident reporting, checklists, theoretical as well as practical education with and without simulators and more use of video technique. The methods described were not new, they had been discussed in the literature sins 1970, but they have been developed.

Abstract (sommario):

Améliorer la gestion et l’organisation des blocs opératoires est une tâche critique dans les hôpitaux modernes, principalement à cause de la diversité et l’urgence des activités impliquées. Contrairement à l’aviation civile, qui a su optimiser organisation et sécurité, le management de bloc opératoire est plus délicat. Le travail ici présenté abouti au développement et à l’installation de nouvelles technologies assistées par ordinateur résolvant les problèmes quotidiens des blocs opératoires. La plupart des systèmes existants modélisent le flux chirurgical et sont utilisés seulement pour planifier. Ils sont basés sur des procédés stochastiques, n’ayant pas accès à des données sûres. Nous proposons une structure utilisant un modèle multi-agent qui comprend tous les éléments indispensables à une gestion efficace et au maintien de la sécurité dans les blocs opératoires, allant des compétences communicationnelles du staff, au temps nécessaire à la mise en place du service de nettoyage. Nous pensons que la multiplicité des ressources humaines engagées dans cette structure cause des difficultés dans les blocs opératoires et doit être prise en compte dans le modèle. En parallèle, nous avons construit un modèle mathématique de flux d’air entre les blocs opératoires pour suivre et simuler la qualité de l’environnement de travail. Trois points sont nécessaires pour la construction et le bon fonctionnement d’un ensemble de bloc opératoire : 1) avoir accès au statut du système en temps réel grâce au placement de capteurs 2) la construction de modèles multi-échelles qui lient tous les éléments impliqués et leurs infrastructures 3) une analyse minutieuse de la population de patients, du comportement des employés et des conditions environnementales. Nous avons développé un système robuste et invisible qui permet le suivi et la détection automatique d’événements dans les blocs. Avec ce système nous pouvons suivre l’activité à la porte d’entrée des blocs, puis l’avancement en temps réel de la chirurgie et enfin l’état général du bloc. Un modèle de simulation numérique de mécanique des fluides de plusieurs blocs opératoires est utilisé pour suivre la dispersion de fumée chirurgicale toxique, ainsi qu’un modèle multi-domaine qui évalue les risques de propagation de maladie nosocomiale entre les blocs. La combinaison de ces trois aspects amène une nouvelle dimension de sensibilisation à l’environnent des blocs opératoires et donne au staff un système cyber-physique capable de prédire des événements rares impactant la qualité, l’efficacité, la rentabilité et la sécurité dans l’hôpital
Improving operating room management is a constant issue for modern large hospital systems who have to deal with the reality of day to day clinical activity. As opposed to other industrial sectors such as air civil aviation that have mastered the topic of industry organization and safety, progress in surgical flow management has been slower. The goal of the work presented here is to develop and implement technologies that leverage the principles of computational science to the application of OR suite problems. Most of the currently available models of surgical flow are used for planning purposes and are essentially stochastic processes due to uncertainties in the available data. We propose an agent-based model framework that can incorporate all the elements, from communication skills of the staff to the time it takes for the janitorial team to go clean an OR. We believe that human factor is at the center of the difficulty of OR suite management and should be incorporated in the model. In parallel, we use a numerical model of airflow at the OR suite level to monitor and simulate environment conditions inside the OR. We hypothesize that the following three key ingredients will provide the level of accuracy needed to improve OR management : 1) Real time updates of the model with ad hoc sensors of tasks/stages 2) Construction of a multi-scale model that links all key elements of the complex surgical infrastructure 3) Careful analysis of patient population factors, staff behavior, and environment conditions. We have developed a robust and non-obtrusive automatic event tracking system to make our model realistic to clinical conditions. Not only we track traffic through the door and the air quality inside the OR, we can also detect standard events in the surgical process. We propose a computational fluid dynamics model of a part of an OR suite to track dispersion of toxic surgical smoke and build in parallel a multidomain model of potential nosocomial contaminant particles flow in an OR suite. Combining the three models will raise the awareness of the OR suite by bringing to the surgical staff a cyber-physical system capable of prediction of rare events in the workflow and the safety conditions

Abstract (sommario):

A gestão do risco clínico e a segurança do doente são componentes essenciais no desenvolvimento de políticas de qualidade nas organizações de saúde. Estas dimensões assumem especial destaque no Bloco Operatório (BO) devido à sua dinâmica complexa, à qual está intrínseco um conjunto de actores com diferentes especificidades e funções, mas com um único objectivo: melhoria contínua da qualidade dos cuidados prestados. Trata-se de um estudo exploratório-descritivo, transversal, de abordagem quantitativa, cujo objectivo é analisar a opinião dos profissionais do BO (enfermeiros, anestesiologistas e cirurgiões), dos hospitais EPE do Alentejo, face à Checklist Cirúrgica, em particular, e às questões da Segurança do Doente em geral. De um modo geral, verificou-se que os profissionais estão sensíveis às questões da segurança do doente, manifestando uma opinião positiva quanto à Checklist Cirúrgica, bem como à sua implementação. Serão apresentadas as diferenças na opinião dos respondentes em função das variáveis independentes estipuladas, quanto à opinião sobre segurança do doente no BO, à identificação de eventos adversos no BO e ao conhecimento de medidas/acções para a melhoria da segurança do doente no intra-operatório; ABSTRACT: The management of clinical risk and patient safety are essential components in developing quality policies on health organizations. These dimensions are particularly highlighted in the Operating Room (OR) because of its complex dynamics, which has an intrinsic set of actors with different specificities and functions, but with a single objective: continuous improvement of care quality. This is an exploratory-descriptive, cross-sectional quantitative approach, which aim is to analyze the opinion of Operating Room’s professionals (nurses, anesthesiologists and surgeons), from EPE hospitals of Alentejo, regarding to Checklist Surgery, in particular, and Patient Safety issues in general. In general, it was found that professionals are sensitive to issues of patient safety, expressing a positive opinion about the Surgical Checklist, as well as its implementation. We will present the differences in the respondents' opinion on the basis of the independent set, as the opinion of patient safety in the OR, the identification of adverse events in the OR and knowledge of measures/actions to improve patient safety during surgery.

Abstract (sommario):

Les blocs opératoires sont l’un des principaux postes de dépenses du système hospitalier, rationaliser et optimiser leur gestion permet donc une réduction des coûts pour la structure. S’aidant de l’unité de chirurgie orthopédique du CHU d’Angers, nous proposons donc des outils d’aide à la planification des interventions chirurgicales prenant aussi en compte les contraintes liées à la stérilisation d’instruments médicaux tels que les kits d’intervention. Le but de ces outils est de baisser les coûts de fonctionnement des blocs opératoires, optimiser le recours aux heures supplémentaires et les stérilisations de matériels en urgence, etc. Nous considérons premièrement que toutes les données sont connues et nous proposons un modèle de type MILP et une heuristique de construction de solutions dont les résultats obtenus améliorent la planification du CHU. Nous adaptons ensuite une approche permettant d’assimiler l’arrivée dynamique des patients et montrons, résultats à l’appui, que cette technique permettrait d’améliorer le processus de prévision des opérations du bloc, si les durées opératoires sont connues. Cette dernière hypothèse ne tenant pas dans le cas réel, nous suggérons de la lever en proposant de robustifier tout d’abord notre approche statique de deux façons que nous adaptons au cas dynamique. A l’issue de ces travaux, une amélioration de 54% est constatée du processus de planification en termes d’heures supplémentaires tout comme une réduction du nombre de stérilisations à effectuer dans l’urgence (90%) et d’une hausse significative du taux d’occupation des blocs opératoires (5.7%)
The operating theater is considered as the most expensive and important resource in hospitals as it counts as the main source of income and expenses. This critical rule and the increase in costs urge hospitals to organize their processes more efficiently and effectively. In this thesis, we will be working with the Centre Hospitalier Universitaire d’Angers (CHU) of Angers in France. We focus on the surgery scheduling problem at the orthopedic surgery unit. The main contribution of this work is the consideration of the activities of the sterilizing unit as a hard constraint and a performancemeasure for the problem. In the first part of this work, we present a multidimensional classification of the current literature on the surgical case scheduling problem. In the second part, we solve the deterministic version of the problem. Starting with the static problem, we propose a MILP and a constructive heuristic and show that the obtained results significantly improve over the ones of the CHU.Next, we solved the deterministic dynamic version by implementing our MILP in a rolling horizon approach. Again, the results were superior to the CHU ones. We then showed that a non-deterministic approach is a must due to the big degradations caused by surgeries duration uncertainties. In the third part, we tackled the non-deterministic version of the problem. Similarly, we started with the static problem and proposed two robust models. Finally, we implement both robust models in a rolling horizon method to solve the dynamic scheduling problem. The results of the both non-deterministic versions show much more robustness compared to the deterministic ones and better values overall

Kravet från samhället är att operationssjuksköterskan ska besitta kompetensen att skydda patienter från vårdskador. World Health Organization har utformat en checklista för att förbättra patientsäkerheten på operation. Syfte: Att undersöka operationssjuksköterskans upplevelse av intraoperativ kommunikation. Metod: En kvalitativ intervjustudie med semistrukturerade frågor utfördes på två sjukhus i södra Sverige. Sju intervjuer hölls med operationssjuksköterskor som spelades in och transkriberades.

Background: Communication in the operating room (OR) is complex. Communication failures is the most reported cause of operative misstakes. Sound levels and operating masks are some factors that complicates the communication. Teamwork in the OR is necessary for patient safe care. The operating team consists of various professionals who are responsible for patient safety intraoperatively. The society’s requirement is that the operating room nurse must possess competence to protect patients from medical harm. The World Health Organization designed a checklist to improve patient safety in the OR. Aim: To investigate the operating room nurse's experience of intraoperative communication. Method: A qualitative interview study with semi-structured questions was conducted at two hospitals in southern Sweden. Seven interviews were held with surgical nurses which were recorded and transcribed. The data were analyzed according to Graneheim and Lundman's (2004) latent content analysis. Results: The result is presented under four themes. The theme The Importance of Communicating highlights that communication must continue throughout the surgery in order not to risk patient safety. The theme of Intraoperative Team Groupings describes that the operating team works in separate teams until the peroperative phase where they are a joint operation team. The professions are linked to each other, which gives great responsibility in communication. The theme The Leader’s Impact on Team Communication reveals that hierarchical leaders can cause a nervous mood and cause reduced patient safety. The surgeon is important for the use of WHO's checklist and its compliance. In the theme Different Expressions for Intraoperative Communication, different types of communication have an impact intraoperatively. Conclusion: The operating team is united by respect and shared responsibility. The quality of intraoperative communication depends on the responsibility of each team member and requires a long term plan for development from the management.

Abstract (sommario):

Despite a number of research studies showing the correlation between higher nurse staffing levels and improved outcomes, RCN members continues to report lower nurse-to-patient ratios than what research results suggests (RCN, 2011:1). This reflected a general concern within the nursing profession. The operating room requires appropriate staffing which is critical to the safety of surgical patients and quality of patient care. The research study was motivated by the researcher’s own experiences while working in an OR in a private hospital where continuous discussions were held with management about the shortage of skilled staff; and where a shortage of OR nurses resulted in the use of Central Sterilizing Department (CSD) staff to do OR duties. The objective of the study was to explore and describe the perceptions of nurses regarding staffing in the operating rooms of a private hospital in the Nelson Mandela Bay Health District. The researcher used qualitative methods and designs to explore and described the perception of nurses regarding staffing in the operating room (OR) of a private hospital in the Nelson Mandela Bay Health District. The research population of the study included all the nurses working in the OR of a private hospital. The total number of 20 OR nurses was individually interviewed by means of semi-structured interviews. Three main themes emerged that includes nurses ‘perceptions with regard to the implications of inadequate staffing in the OR; nurses experiences towards top management with regard to staffing in the OR and recommendations from participants to improve staffing in the OR. Research findings concluded that nurses have a perception that shortage of OR nurses causes lack of communication, physical, emotional and psychological strain. They also perceived OR nurses to work under unrealistic conditions and to receive added responsibilities due to staff shortages, which affect the overall delivery of quality patient care. Comments included failure of management to attend to staff complaints and the perception of high staff turnover due to a lack of recognition and acknowledgement of overworked staff.

Dell Technologies seeks to use the advancements in the field of artificial intelligence to improve its products and services. This thesis aims to implement artificial intelligence techniques in the context of Dell's Client Solutions Division, specifically to analyze the root cause of customer calls so actions can be taken to remedy them. This improves the customer experience while reducing the volume of calls, and hence costs, to Dell. This thesis evaluated the external vendor landscape for text analytics, developed an internal proof-of-concept model using open source algorithms, and explored other applications for artificial intelligence within Dell. The external technologies were not a good fit for this use-case at this time. The internal model achieved an accuracy of 72%, which was above the acceptable internal threshold of 65%, thus making it viable to replace manual analytics with an artificial intelligence model. Other applications were identified in the Client Solutions division as well as in the Support and Services, Supply Chain, and Sales and Marketing divisions. Our recommendations include developing a production model from the internal proof-of-concept model, improving the quality of the call logs, and exploring the use of artificial intelligence across the business. Towards that end, the specific recommendations are: (i) to build division-based teams focused on deploying artificial intelligence technologies, (ii) to test speech analytics, and (iii) to develop a Dell-wide Center of Excellence. The division-based teams are estimated to incur an annual cost $1.5M per team while the Center of Excellence is estimated to cost $1.8M annually.

Surgical technologies since the late 1980s have undergone substantial innovations that have involved ...the adoption of new machines, instruments, and related surgical materials... referred to throughtout this thesis as intra-operative artefacts... typically represents a commitment of substantial financial resources by the hospitals concerned. However, little is documented about the process whereby the decisions are made to adopt new intra-operative artefacts, and no previous research appears to have explored the work-related consequences of new intra-operative artefact adoption within operating theatre services. This thesis explores the reasons why new intra-operative artefacts are adopted, how the decisions are made, who are the participants in the decsion process and what are the expected and actual organisational consequences of new intra-operative artefact adoption.

Resumo: Introdução: A organização do trabalho científico através da lógica e experimentos, a estrutura do estabelecimento de pesquisa individual ou aos diferentes aspectos da vida da comunidade científica foram o eixo de mudanças na relação ciência e tecnologia. A Universidade, dentro deste contexto, se constitui em uma fonte de criação permanente, sistematização e difusão do conhecimento científico e tecnológico. A estatística como instrumento da qualidade se constitui em apoio às ações que visem à otimização dos recursos disponíveis e melhoria da prestação de serviços com qualidade. Objetivo: O estudo proposto, junto à especialidade de Cirurgia Cardíaca/Hospital de Clínicas/Unicamp tem como objetivo identificar um método estatístico que expresse o tempo da presença do doente na sala de operação e construir uma "matriz de relação" de otimização deste tempo, o tempo exato e real da operação. Método: O método de análise de sobrevivência aplicada utilizando o estimador não paramétrico de Kaplan-Meier, permite calcular as curvas de sobrevivência para os tempos em estudo, e com o resultado obtido criar uma "matriz de relação" da otimização do tempo da presença do doente na sala de operação por meio de dez hipóteses que auxiliam na escolha da nova operação, e melhor ocupação da sala. Este estudo tem como parâmetro de referência para o tempo de limpeza da sala de operação, o que a literatura estabelece em aproximadamente 30 minutos, além do tempo de cada tipo de procedimento cirúrgico. A amostra aleatória simples para estimar a curva de sobrevivência constitui-se de 71 pacientes, das operações eletivas de adultos da Cirurgia Cardíaca/Hospital de Clínicas/UNICAMP, durante o ano de 2008. Resultados: Nos resultados encontrados observou-se que os tempos que sobram das operações em média estão em um intervalo de 140 minutos a 200 minutos e excedem de 5 minutos a 90 minutos, para realização de novas operações. No geral, realizou-se em média diariamente uma operação dentro de 520 minutos, para um tempo disponível de 720 minutos. No ano de 2008 foram suspensas 39% das operações, sendo que 81% dos motivos foram "fatores hospitalares extrapacientes" e 19% "relativos ao paciente". Em suma com os resultados obtidos pela metodologia de análise de sobrevivência, metodologia tradicional, e metodologia de gestão da qualidade, é possível cruzar informações e construir passo a passo o conhecimento científico e tecnológico. Conclusão: (1) O tempo do doente na sala de operação é um tempo que tem nele incluso, o tempo de aprendizado pelo aluno, em um hospital escola, universitário. (2) Com o tempo máximo disponível de 720 minutos não é possível realizar outra operação, a não ser utilizando da "matriz de relação", sendo que o tempo máximo disponível varia entre 660 minutos e 690 minutos, considerando-se intervalo de limpeza da sala. (3) Ao otimizar o tempo do doente na sala de operação, através da "matriz de relação", mais doentes serão beneficiados, acarretando uma diminuição da fila de espera para novas operações, garantindo uma eficiente relação custo benefício. (4) A "matriz de relação" fornece dados que permitem visualizar, opinar e decidir qual é a melhor operação a ser realizada e se há tempo disponível para tal

The Academy with this background is the continuing source of sistematization and difusion of scientific acknowledge. Statistics as a tool for a quality control might support actions that may promote the available resources optimization and improvements on services with higher quality. Objective: The present study, carried out with the Cardiac Surgery Discipline at Hospital de Clínicas/Unicamp had the aim to identify the best statistical method for patient time at operation room by fitting and bulding up a model for predicted operation room time, and observed operation room time measurements. Method: The method of survival analysis performed using the nonparametric estimator of Kaplan-Meier allows to calculate the survival curves for time to study. Using this analysis was possible to build up a "relationship matrix" for operation room time optimization, predicted operation room time, and observed operation time by choosing ten different hypotheses which assisted for the next operation type to be performed increasing the operation room time availability. The "relationship matrix" took into account as parameters: time period for operation room disinfection that the consulted literature reports to be around 30 minutes; and surgery procedure type performed. This study included 71 patients underwent open-heart surgeries by Discipline of Cardiac Surgery at Hospital de Clinicas/Unicamp randomly sampled during 2008. Results: The remaining mean operation time after the first surgery in the day ranged from 140 to 200 minutes and the exceeding mean operation time after first surgery in the day ranged from 5 to 90 minutes. The average surgeries performed every day were one procedure spending 520 minutes within 720 minutes available for every day. In 2008, 39% of the procedures were postponed, such that 81% of those due to "hospital related" reasons and 19% to "patient related" reasons. In summary, the results showed above using Kaplan-Meier statistical method, traditional methodology, and managing of quality methodology it was possible to build up a scientific acknowledge. Conclusion: (1) The patient time at the operation room inclued a students learning time a school hospital. (2) With the maximum available time (i.e.720 minutes) it is not possible to perform another operation, nonetheless employing the "relationship matrix", with a maximum available time between 660 and 690 minutes, taking into account were inclued in this interval the disinfection room time. (3) By optimizing the patient time at operation room, more patients will be benefit shorting the wating list time for operations and increasing the cost/benefit ratio. (4) The "relationship matrix" gave data that provided valuable information for choosing next operation type based on remained time

Abstract (sommario):

Au sein d’un établissement hospitalier, le bloc opératoire représente un des secteurs les plus emblématiques et les plus coûteux. Le fonctionnement du bloc opératoire est orchestré par un programme opératoire qui consiste à construire un planning prévisionnel des interventions chirurgicales à réaliser pendant un horizon donné. La littérature abondante sur le sujet est unanime sur le fait que la construction du programme opératoire est une tâche complexe, car il s’agit non seulement de planifier et d’ordonnancer les interventions, mais aussi de satisfaire des exigences souvent antagonistes. Ce projet est le fruit d’une collaboration entre la Communauté d’Agglomération de Sarreguemines Confluences et la Région Lorraine, des membres du secteur hospitalier (Hôpital Robert Pax de Sarreguemines) et l’équipe Gestion Industrielle et Logistique (GIL) du Laboratoire de Génie Industriel, de Production et de Maintenance (LGIPM). L’objectif de cette recherche est d’apporter une aide aux gestionnaires du bloc opératoire, qui ont besoin de plus en plus des méthodes et des outils d’aide à la décision en vue d’optimiser leur fonctionnement. Pour répondre à ce besoin nous nous intéressons dans la première partie de cette thèse à la gestion des opérations électives en prenant en compte différentes contraintes et en particulier la disponibilité des chirurgiens. Nous nous plaçons dans le contexte d’une stratégie « open scheduling » et nous proposons deux modèles mathématiques permettant d’élaborer le programme opératoire. La complexité des modèles mathématiques et leur explosion combinatoire rendent difficile la recherche de l’optimum pour des tailles réalistes. Ceci nous a donc amené à proposer une heuristique constructive utilisant le modèle proposé et permettant d’obtenir des solutions là où la méthode exacte ne nous le permettait pas. Dans la seconde partie de cette thèse, nous considérons l’intégralité du processus opératoire (brancardage vers le bloc opératoire, préparation et anesthésie, acte chirurgicale et réveil). Nous modélisons ce processus comme un flow shop hybride à 4 étages avec contrainte de blocage de type RSb, et nous le résolvons à l’aide d’un algorithme génétique dont l’objectif est de synchroniser toutes les ressources nécessaires, en respectant au mieux le programme opératoire prévisionnel. Outre les opérations électives, nous nous intéressons dans la dernière partie aux opérations urgentes. Nous proposons un outil d’aide à la décision pour la gestion des opérations urgentes. En prenant en considération la pathologie et la gravité de l’état du patient, nous distinguons principalement 3 degrés d’urgences et proposons pour chacune un algorithme permettant d’intégrer en temps réel ces opérations dans le programme prévisionnel, tout en minimisant différents critères (temps d’attente avant affectation, heures supplémentaires, décalage par rapport aux anciennes dates de débuts)
The operating theater is one of the most critical and expensive hospital resources. Indeed, a high percentage of hospital admissions are due to surgical interventions. Rising expenditures spur health care organizations to organize their processes more efficiently and effectively. This thesis is supported by the urban community of Sarreguemines-France and the region of Lorraine-France, and is carried out in collaboration with the Centre Hospitalier de Sarreguemines - Hôpital Robert Pax. In the first part of this work, we propose two mathematical programming models to help operating theater managers in developing an optimal operating rooms scheduling. We also propose a constructive heuristic to obtain near optimal results for realistic sizes of the problem. In the second part of our work, the whole scheduling process is modeled as a hybrid four-stage flow shop problem with RSb blocking constraint, and is solved by a genetic algorithm. The objective is to synchronize all the needed resources around the optimal daily schedule obtained with the proposed mathematical model. The last part of our work is dedicated to non-elective surgeries. We propose a decision support tool, guiding the operating room manager, to handle this unpredictable flow of patients. Non-elective patients are classified according to their medical priority. The main contribution of the proposed decision support tool is to provide online assignment strategies to treat each non elective patient category. Proposed assignments are riskless on patient’s health. According to non-elective surgery classes, the proposed adjusted schedule minimizes different criteria such as patient’s waiting time, deviation from the firstly scheduled starting time of a surgery and the amount of resulting overtime

Abstract (sommario):

Epiroc har åtnjutit en längre period av kraftig tillväxt samtidigt som flertalet effektiviseringsprojekt har genomförts med syfte att öka produktionsvolymen för att möta marknadens efterfrågan. Detta genom att bland annat implementera en variant av Lean production – The Way We Produce. En av dessa förändringar är en takad flödesorienterad montering med just-in-time sekvenserad materialförsörjning. Detta har i sin tur ökat kraven på materialförrådet Logistikcenter (LC) där ledningen nu börjat undersöka möjliga effektiviseringsåtgärder. Därav är studiens syfte till att ta fram realiserbara förbättringsförslag för logistikverksamheten vid Logistikcenter tillhörande Epiroc Rock Drills AB i Örebro för att öka effektiviteten och leveranssäkerheten. Studien har genomförts i två faser; identifieringsfasen och fördjupningsfasen. Under identifieringsfasen genomfördes en kartläggning av nuläget i LC, där underlaget för kartläggningen baserar sig på intervjuer, observationer och analyser. Genom en rotorsaksanalys, med målet att identifiera källor till ineffektivitet, kunde nio förbättringsområden identifieras varav en av dessa vidare skulle utredas i fördjupningsfasen. Dessa utvärderades utifrån en effekt-insats matris för att välja det förbättringsområde med störst effektiviseringspotential i förhållande till den förväntande insatsen. Analysmodellen för effekt-insats matrisen var de åtta slöserierna i Lean (Petersson, et al., 2015), dess förväntade påverkan på effektiviteten samt den förväntade komplexiteten av en implementation. Resultatet från rotorsaksanalysen gav artikelklassificering som det primära förbättringsområdet där den undersökta åtgärden var en alternativ tillämpning av frekvensläggning för att minimera rörelsetiden mellan lagerplatser vid plock. Under fördjupningsfasen undersöktes den nuvarande artikelklassificeringen och frekvensläggningen genom syntes av en alternativ modell för klassificeringen av artiklar och lagerplatser utifrån en fördjupad litteraturstudie. För att undersöka om en alternativ klassificering kan öka effektiviteten utvecklades en utvärderingsmodell som modellerar rörelsetiden för historiskt data från plocklistor. Den användes för att testa vilken kombination av storlekar på artikelklasserna som gav den minsta möjliga totala rörelsetiden. En kombination av 60/30/10 % (A/B/C) av det ackumulerade antalet plock gav den lägsta totala rörelsetiden för en plockhistorik på 15 månader med en reduktion av rörelsetiden motsvarande 33 % (1760 h) jämfört mot nuläget. Vidare undersöktes en alternativ sortering av plocklistorna för automathissar respektive pallställage med utvärderingsmodellen som gav en reduktion på 4 % respektive 11 % mot nuläget. Slutligen undersöktes olika former på zonerna för klassificering av lagerplatser i pallställage W3, där utlämningsplatsen är placerad halvvägs in i ställaget. En tyngdpunkt placerat centralt mellan ingången och utlämningsplatsen gav det bästa simuleringsresultatet. Sammanfattningsvis fastställdes artikelklassificering som det förbättringsområde med störst realiserbar effektiviseringspotential med lägst komplexitet utifrån en rotsorsaksanalys. Epiroc rekommenderas att implementera klassificeringsmodellen med tre klasser av storleken 60/30/10 % (A/B/C) av den ackumulerade antalet plockrader, samt att implementera att den alternativa sorteringen av plockrader på plocklistor för pallställage.
Epiroc has had a long period of strong growth, where several efficiency projects have been implemented to increase production volume in order to meet market demand. A variant of Lean production has been implemented over several years – called The Way We Produce by Epiroc. A large part of that change has been the implementation of sequenced flow-oriented assembly with just-in-time sequenced material deliveries to the assembly floor. This, in turn, has increased the requirements for the warehouse Logistic Center (LC) and management has now begun to investigate ways to improve efficiency at LC. Hence, the aim of the study is to develop realistic improvement proposals for the logistics operations at Logistics Center of Epiroc Rock Drills AB at Örebro to increase efficiency and delivery reliability. The study has been conducted in two phases; the identification phase and the in-depth phase. During the identification phase, a mapping of the current situation in LC was carried out, where the basis for the survey is based on interviews, observations and analyzes. Through a root cause analysis, with the goal of finding sources of inefficiency, nine areas of improvement could be identified, one of which would be chosen for further investigation in the in-depth phase. The areas of improvement were evaluated with an effect-input matrix to choose the area of improvement that provides the greatest efficiency potential in relation to the expected effort. The analysis model for the effect-input matrix was the eight wastes of Lean based on Petersson et al. (2015), its expected impact on efficiency and the expected complexity of an implementation. The result of the root cause analysis gave article classification as the primary area of improvement, where the measure is an alternative slotting strategy to minimize the movement time between storage locations. During the in-depth phase, the current article classification and frequency setting were examined by synthesis of an alternative model for the classification of articles and storage locations based on an in-depth literature study. To investigate whether an alternative classification can increase efficiency, an evaluation model was developed that models the movement time from historical data from pick lists. It was used to test which combination of sizes for the article classes gave the smallest possible total movement time. A combination of 60/30/10% (A/B/C) gave the lowest total movement time for a picking history of 15 months with a reduction corresponding to 33% (1760 h) compared to the current situation. Furthermore, an alternative sorting of the pick lists for the vertical lift modules and pallet racking was examined with the evaluation model, which gave a reduction of 4% and 11% respectively. Finally, various forms for the zones were examined for the classification of storage locations in pallet rack W3, where the delivery site is located three-quarter way into the pallet rack. A center of gravity for the for the A-class placed between the entrance and the delivery point gave the best simulation result. In summary, the article classification improvement area was established with the greatest realizable efficiency potential with the least effort based on the root cause analysis. Epiroc is recommended to implement the classification model with three classes of size 60/30/10 % (A/B/C) of the accumulated number of picking rows, and to implement that alternative sorting of pick rows on picklists for pallet racking.

Objective Healthcare system now, with global budget payment, is facing an increasing challenge mainly due to patient oriented environment, more demand for service quality and organizational re-arrangement. Also due to the high cost of personalle and equipments in the operation room , it is quite important to maintain the high efficiency of management to encompass high volume of surgeries. Staffing and scheduling is the most important issue in the management of the operating room and has direct impact on the operational efficiency, cost and revenue. The purpose of this study is to investigate the influence of staffing and scheduling of the operating room on its efficiency. How we control the sum of the patients requiring operation under present circumstances lies on whether or not we have efficient management of the operation room. The most important part among it depends on the ability of schedule arrangement, which directly influence the performance audit and cost. Materials and Methods:The purpose of this study is to discuss the impact of schedule arrangement on cost in the operation room of one medical center. Retro spective descriptive design. Those first operations performed from July 1st, 2003 to June 30th, 2004 were collected into the controlled group while those performed from July 1st, 2004 to June 30th, 2005 were gathered into the experimental group. Indicators of the effect including the sum of the patients receiving operation, the utilization rate of the operation room, the cancellation rate of scheduled operation, the number of overtime nursing staff and overtime payment, the delayed rate and time of the first operation. We use ANOVA, x2 test, multiple logistic regression and t test to analyze these data. We will discuss issues as the followings to smooth our operation schedule: the arrangement of the fist operation by program manager, setting up a flow chart for nursing staff while admitting the patients, establishing a check-in flow chart for patients of out-patient department and deployment of pageboys. Results: The data showed that the incidence of delaying surgery were decreased by 8.4% in the experiment group as compared to the control group. The operation room occupation rate increased to 84.3% in control group, as compared to 78.25% in experiment group. There is 0.76% decrease in the rate of canceling operation schedule . The number of nursing staff who worked overtime and the overtime payment decreased significantly. The time needed from patients entering operation room to the operation began also decreased significantly. The rate of delaying the first scheduled operation decreased from 52.8% to 12.3%. Conclusion: Operation room managers, leader in department of surgery, and hospital managers could take our results as reference in improving efficiency and decreasing cost.

Abstract (sommario):

abstract: Surgery is one of the most important functions in a hospital with respect to operational cost, patient flow, and resource utilization. Planning and scheduling the Operating Room (OR) is important for hospitals to improve efficiency and achieve high quality of service. At the same time, it is a complex task due to the conflicting objectives and the uncertain nature of surgeries. In this dissertation, three different methodologies are developed to address OR planning and scheduling problem. First, a simulation-based framework is constructed to analyze the factors that affect the utilization of a catheterization lab and provide decision support for improving the efficiency of operations in a hospital with different priorities of patients. Both operational costs and patient satisfaction metrics are considered. Detailed parametric analysis is performed to provide generic recommendations. Overall it is found the 75th percentile of process duration is always on the efficient frontier and is a good compromise of both objectives. Next, the general OR planning and scheduling problem is formulated with a mixed integer program. The objectives include reducing staff overtime, OR idle time and patient waiting time, as well as satisfying surgeon preferences and regulating patient flow from OR to the Post Anesthesia Care Unit (PACU). Exact solutions are obtained using real data. Heuristics and a random keys genetic algorithm (RKGA) are used in the scheduling phase and compared with the optimal solutions. Interacting effects between planning and scheduling are also investigated. Lastly, a multi-objective simulation optimization approach is developed, which relaxes the deterministic assumption in the second study by integrating an optimization module of a RKGA implementation of the Non-dominated Sorting Genetic Algorithm II (NSGA-II) to search for Pareto optimal solutions, and a simulation module to evaluate the performance of a given schedule. It is experimentally shown to be an effective technique for finding Pareto optimal solutions.

Hospital management has always been a focus of the public, yet very little attention has been given to the management of bone banks in the operating room. Clinical practices have found that problems with the bone banks can harm both the patient and the healthcare personnel while decreasing the quality of medical services. This paper is a case study on the Chang Gung Memorial Hospital bone bank that analyzes and redesigns the workflow. We analyzed the workflow to find the activities that were valuable (for the patients, hospital, and healthcare personnel) and which were not valuable and were wasteful. The analysis showed that the freezers are a mess, and the space needs to be better utilized. This paper also suggests using automatic identification technology to improve the workflow. Also, this paper suggests using two dimensional code, including QR code, as the bone identification code for automatic identification. Tests showed that QR code printed on the water-proof bags stored in freezers at low temperatures (-80℃) was not corrupted or rendered unreadable. The system discussed in this paper has a search function, a function to provide positioning information, an identification function and a prompting function. A redesigned workflow with this system can help healthcare personnel effectively find bones and store bones in an orderly fashion. By shortening storage and search times, systematizing use of freezer space, and providing correct identification and complete medical records, the quality of bone management is improved, and patients are safer. Key words: Bone bank, workflow management, patient safety

Operating room managers who seek to maximize utilization in their operating room suite may attempt to build an efficient operating room scheduling. The objectives of this study are to find the best fit time distributions of each operation code and thus make time prediction based on that and to implement the theorem and technique of simulation on management and to evaluate the performance of the operating room. This research uses the BEST-FIT software to find the best fit time of each operating code and applies the eM-Plant simulation software to construct models and to analyze the output performance. According to the model we constructed, several findings were explored: The first alternative using block and single-room scheduling system will shorten the operating time and reduce the work overtime. The second alternative, first come first serve scheduling system, will shorten the patient waiting time. The third alternative, close the operating rooms that with utilization rate under 30%, then the average utilization rate increase but the work overtime not. The fourth alternative, open an extra emergency operating room and require that the emergency patient can only be sent to this room, then the average waiting time will be increased. The fifth alternative, open an emergency operating room and require that the emergency patient can be sent to this operating room or others, then the average waiting time will be reduced. The sixth alternative, the emergency patient can be sent to all kind of operating room with first available condition, then patient almost need not wait.

As a society becomes more affluent, and medical technologies more advanced, the public’s awareness of their health expands; consequently, healthcare expenses soar. The statistical data collected between 2004 and 2012 by the Ministry of Health and Welfare shows that the number of people visiting inpatient surgery increased from 3,499,066 to 4,592,685, a rate of 13%. Such a steady increase suggests that the public’s demand for surgical rooms is increasing. Consequently, OR procedure management has become more important when the public is subsequently in the surgical system. It is not only the allocation of medical resources that has to be more effective in order to improve service quality. More importantly, the time required for OR procedures must be reduced, and staff and OR idle time must be reduced in order to enhance OR revenue, improve healthcare quality and lower business operating costs. The research data used in this paper is the actual OR patient-processing time of a medical center in central Taiwan. This paper adopted the real-life patient-processing time as the base, and incorporated the actual value and simulation value of each OR index (patient’s time spent in the waiting room and the post anesthesia care unit (PACU), average daily number of patients, and OR utilization rate) as the simulation data. This paper utilized the formula function of EXCEL, applied normal distribution to obtain simulated values, and subsequently sorted out indicator values, and then constructed the simulation system for OR procedures. To find the optimal fit for every indicator of the OR procedure, this paper introduced the hospital’s realistic data and simulation value into the simulation system to compare the differences between actual values and simulation values. Using response surface methodology, an optimal regression formula was found for each of the paired values. A genetic algorithm was applied to the optimal regression formula to obtain the best solution for every variable, i.e. “optimal configuration” for each indicator. Lastly, sensitivity analysis was performed to observe the relationship between input and output data, and to validate the accuracy of the optimal configuration. Research findings of this paper show that optimal configuration does not imply that the configuration is a combination of maximized or minimized values alone. In fact, when the waiting time is at a minimum, which reduces procedure time, and manpower costs, and thus improves performance value; the average daily number of patients is at a maximum, which reduces the staff’s idleness and improves performance value; and with the OR utilization rate and PACU time within moderate ranges, the configuration is at its optimal solution. Improvement and Target: OR waiting time should be reduced by 9.258 minutes, OR utilization rate should be increased by 11.87%, average daily number of patients should be increased to 28.5 people, and PACU time should be under 160.82 minutes, to fit the optimal model.

Abstract (sommario):

In April 2008, the Ontario government announced its top two healthcare priorities for the next 4 years, one of which is reducing wait time in emergency rooms. To study the wait time in emergency rooms or any other departments in a hospital, one must investigate resource planning, scheduling, and utilization within the hospital. This thesis provides hospitals with a set of simulation and optimization tools to help identify areas of improvement, particularly when there are a number of alternatives under consideration. A simulation tool (a Monte Carlo simulation model) estimates patient demand for beds in a hospital during a typical week. Two optimization tools (an integer programming mathematical model and a heuristics model) demonstrate opportunities for smoothing the patient demand for beds by adjusting the operating room schedule.

Abstract (sommario):

Os equipamentos médicos são hoje um componente determinante na prestação de cuidados de saúde. Não só têm contribuído para a melhoria do diagnóstico e da terapêutica de várias doenças, potenciando o extraordinário desenvolvimento das ciências médicas e das suas inúmeras especialidades, mas têm também contribuído para níveis de complexidade e risco cada vez maiores. Num momento em que a segurança dos doentes, ou as consequências decorrentes da falta da mesma, se destaca como um problema de crucial preocupação a nível mundial, compreender o papel que os equipamentos médicos desempenham neste campo emerge de enorme importância. Neste sentido, pretendeu-se com este estudo conhecer a ocorrência de eventos adversos em bloco operatório e compreender as suas origens com foco na dimensão tecnológica. Para compreender melhor esta realidade, este estudo abordou ainda as vertentes da cultura organizacional e da cultura de equipa. Foi assim adoptado como metodologia de investigação o estudo de caso, seleccionando-se dois procedimentos cirúrgicos em urologia no Centro Hospitalar Lisboa Norte. Como método de recolha de dados adoptou-se entrevistas e observação directa e os dados foram analisados por meio da análise de conteúdo. Concluiu-se que a avaria dos equipamentos médico-cirúrgicos é o sintoma efectivo de disfuncionamentos organizacionais. A fadiga, distracção ou falta de atenção e falta de comunicação entre a equipa cirúrgica foram os problemas-chave e problema raiz identificados. É sobre estas causas potenciadoras de acidentes que se devem centrar as acções de melhoria, visando a consequente redução de eventos adversos e melhoria da prestação de cuidados de saúde.
Medical equipment has now become a crucial component in the provision of health care. Not only have contributed to improving the diagnosis and treatment of various diseases, thus enhancing the extraordinary development of medical science and its many specialties, but have also contributed to levels of complexity and risk increasing. At a time when patient safety, or the consequences of the lack of it, stands out as an issue of crucial concern worldwide, understand the role that medical equipment play in this field emerging of great importance. In this sense, it was intended with this study to understand the occurrence of adverse events in the operating room and understand their origins with a focus on the technological dimension. To better understand this reality, this study has also addressed the aspects of organizational culture and team culture. It was adopted as the research methodology case study, selecting two surgical procedures in urology at the Centro Hospitalar Lisboa Norte. As a method of data collection was adopted interviews and direct observation and the data were analyzed using content analysis. It was concluded that the breakdown of medical and surgical equipment is the symptom of effective organizational dysfunctions. Fatigue, distraction or lack of attention and lack of communication between the surgical team were the key problems and root problem identified. It's about these potential causes of accidents should focus on measures to improve, seeking a consequent reduction of adverse events and improving the delivery of health care

Abstract (sommario):

O tema da sustentabilidade ambiental é marcado pela preocupação com a escassez dos recursos naturais, com a poluição, com as alterações climáticas e com as respetivas consequências nos ecossistemas. Um dos maiores contribuidores para o impacto ambiental, entre as organizações prestadoras de cuidados de saúde, são os hospitais. O Bloco Operatório em concreto, caraterizado pela sua complexidade e por ser um grande consumidor de recursos e, consequentemente, um grande produtor de resíduos hospitalares, deve ser o motor de inspiração de um projeto estratégico de gestão ambiental e apresentar-se como um impulsionador para toda a organização hospitalar. A metodologia deste projeto recorreu à análise documental relevante e ao benchmarking. Procedeu-se também à realização de entrevistas e de um inquérito dirigidos a grupos profissionais relevantes na área da sustentabilidade ambiental e envolvidos no funcionamento do Bloco Operatório do Centro Hospitalar Universitário de Lisboa Central. Este estudo é de caráter exploratório e o plano de pesquisa baseia-se numa metodologia qualitativa e quantitativa. Verificou-se que a perceção que os profissionais de saúde têm acerca da sustentabilidade ambiental na prestação de cuidados de saúde na área do Bloco Operatório é reduzida, tendo sido identificadas áreas críticas suscetíveis de ações de melhoria. Deste trabalho resultou um plano de melhoria intitulado "Plano Estratégico e Operacional de Sustentabilidade Ambiental no Bloco Operatório", que promove a implementação de medidas e de comportamentos que resultam num menor impacto ambiental.
The environmental sustainability issue is marked by the ever-growing concern of the scarcity of natural resources, pollution, climate change and their respective consequences on ecosystems. One of the biggest contributors to the environmental impact, among health care providers, are hospitals. The Operating Room in concrete, characterized by its complexity and for being a large user of resources and, consequently, a large producer of hospital waste, it should be the driver of change for a strategic environmental management project presenting itself as a booster for the entire hospital organization. This project´s methodology used relevant document analysis and benchmarking. Interviews and an inquiry were also carried out with professional groups which are more relevant in the area of environmental sustainability and involved in the Operating Room of the Centro Hospitalar Universitário de Lisboa Central. This study is exploratory in nature and the research plan is based on a qualitative and quantitative methodology. It was found that the perception professionals have of environmental sustainability in the provision of health care in the Operating Room area is reduced, having been considered as critical areas susceptible to improvement actions. This work resulted in an improvement plan entitled "Strategic and Operational Environmental Sustainability Plan in the Operating Room", which promotes the implementation of measures and behaviors that lead to a lower environmental impact

With the advance of medical technology, traditional surgery has failed to meet the demand. The current stage of surgery has been towards a more advanced minimally invasive surgery(MIS). Different from the traditional open surgery, MIS can be faster, safer, and reduce recovery time. MIS only minor wounds but no unnecessary wounds. This is also a painless operation with precise control of the operation time and minimal blood loss. Currently, there are many medical devices in the operating room for MIS. Various types of imaging equipment in the operating room need to be integrated and managed. The study will design an operating room image integration system based on the images provided by the existing imaging equipment in the operating room. We use a variety of hardware and software equipment to plan and build the system. We will build the system with Stage-Gate and V-Model. And we will use Microsoft operating system platform for development. The purpose is to optimize the presentation of operating room images, to continuously improve the understanding of the surgical team, thereby enhancing the quality of surgery.

According to a number of researches, the survey found that the average cost of medical materials accounts for about 30% to 40% of the total operating costs. Therefore, the management of medical materials plays a crucial role in hospitals. This research focuses on inventory management in operation room of Taoyuan Armed Forces General Hospital (TYAFGH). We went to the hospital intermittently (September, 2012 - December, 2013) for 100 days to observe the inventory management process and collect data of the operation rooms. However, the inventory management theory of business and industrial fields apply to the medical field is difficult. While managing the materials used in operation room, a few special demand will emerge. Therefore, most of the quantitative classification cannot classify them effectively. From what’s discussed above, this research will develop material management model specifically for TYAFGH’s operation room. This model will be simple-to-understand and easy-to-use to assist material administrator to reduce material cost by an average of 25% while still keep the healthcare service quality. This research has two steps, first step is that classification is based on characteristic of operation room materials, and the second step is to make demand forecasts for each classification, and propose the inventory policy. Finally, we will go to TYAFGH and apply the inventory management improvements step of this research to conduct simulated assessment. The contribution of the research is that effectively reduce 25% inventory cost without any material out of stock.

The payment system of the National Health Insurance has undergone a radical transformation in recent years. As a result of the recent introduction of the global budget on July 1, 2002, hospital administrators as well as managers of the operating rooms (OR) are paying more attention to cost analysis and cost containment than they used to be. With the new challenge, OR managers attempt to reward good resource utilization and cost containment during the entire surgical process in order to obtain adequate profits. Thus, the purpose of this research is to provide a framework for analyzing actual costs of surgical services by using a multiple-stage activity-based costing/management (ABC/M) model to improve OR efficiency. Surgical services, in fact, are provided through an integrated process of multiple stages, which is a series of interconneted steps that consume common resources such as anesthesia services, operation rooms, and post-anesthesia care. With the recognition that there are multiple stages in the OR to serve as cost drivers, the diversity of the resources consumed can be better segmented to truly reflect the variety and operational complexity of surgical services. The data of costs and charges for 31,358 patients received surgery at a certain 2000-bed medical center from January to December in 2001 are analyzed in this study. The study follows a four-step process to identify and define the activities in the OR and its associated costs. First, three activity centers are defined. They are the anesthesia department, the OR department, and the post-anesthesia care unit. Secondly, the total OR costs are assigned to these activities centers based on first-stage cost drivers. Thirdly, the OR department cost is assigned to the activities of customized pack preparation and instrument sterilization through the use of appropriate intermediate cost drivers. The activity costs progressively accumulated are then subsequently reassigned to surgery-specific supporting and surgical activities Finally, costs are flowed and reassigned to the appropriate surgical procedures in the cost centers associated with all appropriate activities by the final-stage cost drivers. The findings of this research are as follows. There are nineteen activities and 902 cost objects are identified. Our result shows that seventy-eight percent (78%) of operating costs are fix costs. Twenty-two percent (22%) of total costs are variable. The largest surgical activity center is the OR department (52.2%), followed by the anesthesia activity center (43.8%) and the post-anesthesia care activity center (3.9%). The result also shows that the surgical cost per patient ranges from NT$10,996 to NT$70,294 across the entire surgical services of the medical center and the mean is approximately NT$13,966. The profit analyses suggest that the net profit rate is29.2% for the entire surgical services. On the other hand, the break-even quantity is 14,282 patients per year for the operating rooms. Through this study, it can be concluded that the multiple-stage ABC/M system is applicable in the operating rooms. In addition, this new costing system not only provides cost information on activities and surgical procedures but also assists resource management and cost control. Moreover, the new system can provide financial and non-financial information to help OR managers in the analysis of the OR activities/business and, thus, enhance their decision-making. Finally, this system can also help hospitals to set up a private physician’s fee (PPF) system based on the degree of resources consumed.

Abstract (sommario):

O presente trabalho pretende recolher informação sobre o balanced scorecard implementado nos três blocos operatórios dos Hospitais do SNS que no ano de 2013 alcançaram os melhores resultados (% de utilização) ao nível da capacidade utilizada do bloco operatório e, a partir dos dados obtidos, desenvolver um balanced scorecard que possa ser aplicado de uma forma genérica à globalidade dos blocos operatórios dos hospitais do SNS. É um facto que o aumento das listas de espera cirúrgicas é uma preocupação sempre presente na agenda política. Ao longo dos anos, através de programas diversos de combate às listas de espera, tem-se tentado reduzir o tempo de espera cirúrgica para níveis aceitáveis, centrando-se os holofotes da gestão hospitalar na eficiência dos blocos operatórios. O balanced scorecard surge como um modelo de gestão para medir a performance das organizações. Desenvolvido pelos Professores Robert Kaplan e David Norton, em 1992, este modelo apresenta quatro perspetivas: clientes, financeira, processos internos e aprendizagem e crescimento. Para cada uma destas perspetivas são definidos objetivos e indicadores, que possibilitam a medição e o acompanhamento da estratégia da organização. Pretende-se, em suma, construir um BSC para o bloco operatório que possa ser replicado noutros Hospitais, como uma ferramenta de suporte à gestão estratégica e que concorra para o alinhamento entre as visões (por vezes antagónicas) dos grupos profissionais presentes no Hospital.
This work intends to gather information on the balanced scorecard implemented in the three operating theaters in SNS hospitals which in 2013 achieved the best results (% utilization) at the level of capacity utilization of the operating room and, from the data obtained, develop one balanced scorecard that can be applied in a general way to the whole of the operating theaters in SNS hospitals. It is a fact that increased surgical waiting lists is an ever-present concern on the political agenda. Over the years, through various programs to combat waiting lists has been tried to shorten surgical waiting to acceptable levels by focusing the spotlight on the efficiency of hospital management of operating theaters. The balanced scorecard emerges as a management model to measure the performance of organizations. Developed by Professors Robert Kaplan and David Norton in 1992, this model has four perspectives: customer, financial, internal processes and learning and growth. For each of these perspectives objectives and indicators that enable measuring and monitoring the strategy of the organization are defined. It is intended, in short, build a BSC for the operating room that can be replicated in other hospitals, as a support tool for strategic management and contributes to the alignment between the views (sometimes conflicting) professional groups present in the Hospital.

Currently, high-tech manufacturers for electronic industry in Taiwan generally will set up Management Information System (MIS) rooms for connecting each production line, office and warehouse, etc by those internet devices and equipments inside MIS rooms. The MIS plays a very important role in managing both the internal production, inventory, goods acceptance, goods delivery and the external orders and delivery informations. The sensible loading of air-conditioning is very significant and the main heat resource is from the heat released by the operation of the inside electronic networks and communication equipments. The purpose of setting up air-conditioning in MIS rooms is to ensure the equipments working under the proper environment in case of any unstable breakdown. By studying the cases of supplying air on the raised floor, this study probes into how to match the temperature of MIS racks and the circulating airflow rates of air–conditioning system in MIS rooms. In order to control the temperature of racks surroundings, this study also probes into how to reach the proper supplying air temperature and volume by controlling the volume of both airflow generated by the fan and chilled water of the cooling coils in air handing units. The main purpose is to know the changes of racks temperature by studying four models which are under different control parameters respectively. According to this method of data analysis, this study compares the advantages with disadvantages of these models and find the optimal operation solution for air handing units in MIS rooms. In addition, this sudy is also a reference for relevant technians who are in charge of designing or daily operation. This study obtains the following achievements: The model of variable circulating airflow rates and waterflow rates is the optimal one which has the lowest unusual discrepant proportion in rack temperature : 68%. What’s more, the adjustment ability of loading changes is also the best one which is between – 25.24% and + 11.51%. Comparing with the commonly adopted model of constant circulating airflow rates and variable waterflow rates, this optimal model reduces 18.18 % of air-side electric fee and electric consumption annually. The increasing amount proportion of building this project for this study case is about 10.0 % and the amount retrieving time is about 8.1 years.
