Resumen
This thesis discusses how Multi-agent Systems (MAS) should be designed in the context of diabetic health care. Three fields are touched: computer science, socio-psychology and systems science. Agent Technology is the core technology in the research. Theories from socio-psychology and systems science are applied to facilitate the discussion about computer agents. As the integration of socio-psychology and systems science, Activity Systems Theory is introduced to give a synthesized description of MAS. Laws and models are introduced with benefits on both individual agent and agent communities. Cybernetics from systems science and knowledge engineering from computer science are introduced to approach the design and implementation of the individual agent architecture. A computer agent is considered intelligent if it is capable of reactivity, proactivity and social activity. Reactivity and proactivity can be realized through a cybernetic approach. Social activity is much more complex, since it considers MAS coordination. In this thesis, I discuss it from the perspectives of socio-psychology. The hierarchy and motivation thinking from Activity Systems Theory is introduced to the MAS coordination. To behave intelligent, computer agents should work with knowledge. Knowledge is considered as a run-time property of a group of agents (MAS). During the MAS coordination, agents generate new information through exchanging the information they have. A knowledge component is needed in agent’s architecture for the knowledge related tasks. In my research, I adopt CommonKADS methodology for the design and implementation of agent’s knowledge component. The contribution of this research is twofold: first, MAS coordination is described with perspectives from socio-psychology. According to Activity Systems Theory, MAS is hierarchically organized and driven by the motivation. This thesis introduces a motivation-driven mechanism for the MAS coordination. Second, the research project Integrated Mobile Information Systems for health care (IMIS) indicates that the diabetic health care can be improved by introducing agent-based services to the care-providers and care-receivers. IMIS agents are designed with capabilities of information sharing, organization coordination and task delegation. To perform these tasks, the IMIS agents interact with each other based on the coordination mechanism that is discussed above.

Resumen
Patient data in health care have traditionally been used to support direct patient care. Although there is great potential in combining such data with genetic information from patients to improve diagnosis and therapy decisions (i.e. personalized medicine) and in secondary uses such as data mining, this is complex to realize due to technical, commercial and legal issues related with combining and refining patient data. Clinical decision support systems (CDSS) are great catalysts for enabling evidence-based medicine in clinical practice. Although patient data can be the base for CDSS logic, it is often scattered among heterogenous data sources (even in different health care centers). Data integration and subsequent data mining must consider codification of patient data with terminology systems in addition to legal and ethical aspects of using such data. Although computerization of the patient record systems has been underway for a long time, some data is still unstructured. Investigation regarding the feasibility of using electronic patient records (EPR) as data sources for data mining is therefore important. Association rules can be used as a base for CDSS development. Logic representation affect the usability of the systems and the possibility of providing explanations of the generated advice. Several properties of these rules are relatively easy to explain (such as support and confidence), which in itself can improve end-user confidence in advice from CDSS. Information from information sources other than the EPR can also be important for diagnosis and/or treatment decisions. Drug prescription is a process that is particularly dependent on reliable information regarding, among other things, drug-drug interactions which can have serious effects. CDSS and other information systems are not useful unless they are available at the time and location of patient care. This motivates using mobile devices for CDSS. Information structures of interactions affect representation in informatics systems. These structures can be represented using a category theory based implementation of rough sets (rough monads). Development of guidelines and CDSS can be based on existing guidelines with connections to external information systems that validate advice given the particular patient situation (for example, previously prescribed drugs may interact with recommended drugs by CDSS). Rules for CDSS can also be generated directly from patient data but this assumes that such data is structured and representative. Although there is great potential in CDSS to improve the quality and efficiency of health care, these systems must be properly integrated with existing processes in health care (workflows) and with other information systems. Health care workflows manage physical resources such as patients and doctors and can help to standardize care processes and support management decisions through workflow simulation. Such simulations allow information bottle-necks or insufficient resources (equipment, personnel) to be identified. As personalized medicine using genetic information of patients become economically feasible, computational requirements increase. In this sense, distributing computations through web services and system-oriented workflows can complement human-oriented workflows. Issues related to dynamic service discovery, semantic annotations of data, service inputs/outputs affect the feasibility of system-oriented workflow construction and sharing. Additionally, sharing of system-oriented workflows increase the possibilities of peer-review and workflow re-usage.

Resumen
This thesis explores change and resistance to change of IT systems in organisations from a sociotechnical perspective. The work is drawing on empirical data gathered during two Action Research projects in Swedish Health Care: one regarding the deployment of electronic patient record systems within health care organisations, and the other regarding the deployment of eHealth services geared towards patients and citizens. Resistance to change is classified as an indicator of social inertia, and the concept of counter-implementation, comprising three general strategies to obstruct change initiatives, is used to highlight the political aspects of social inertia. For the analysis, the concept of social inertia is used as a point of departure towards inertia in sociotechnical systems by applying values and principles from sociotechnical systems research, most prominently the interdependence-characteristic. This extended concept is used to show and discuss how IT systems can either enforce change or be a source of inertia preventing change in organisations, and such planned or inadvertent effects of implementing IT systems are discussed as a significant source of user resistance.

Kyhlbäck, Hans. "The Problem of Objects in Design of Health Care Information Systems". Licentiate thesis, Karlskrona : Blekinge Institute of Technology, 2005. http://urn.kb.se/resolve?urn=urn:nbn:se:bth-00293.

Resumen
This thesis is about two different theoretical interpretations of objects and object-orientation in design of health care information systems – the interpretations of Activity Theory/Developmental Work Research and Computer Science respectively. One motive to my interest in objects of work and software, is to better understand the problems and possibilities in an inter¬dis¬ciplinary research project. With an origin in 2001, a Wound Care Project began as a joint R & D endeavour with the initial idea of utili¬zing digital photos. Soon, an information system (“Hedvig”) was developed for the purpose of managing digital photos and related treatment records on wounds. Later, this work expanded in creation of a distributed information system (“Helar”), a digital prototype for support of wound care treatment. Eventually, the thesis is summing up reflections related to the object concepts. AT/DWR has its strength in analysis and design of required change in a work practice but is still weak in method and techniques for support of making specific computa¬tional systems. In a way this shortcoming is thought of to be balanced by the technological CS discipline of which one of its main forces is to develop theory and practice for construction of computational information systems. This thesis suggest, in the inter¬dis¬ciplinary field of Health Care Information Systems Design, a further developed object con¬cept, and related scenarios and use cases, as a way of taking advantage of a combination of those two different strengths.
Avhandlingen handlar om två olika teoretiska tolkningar av objekt och objektorientering i design av informationssystem för hälso- och omvårdnadsarbete - tolkningar utifrån verksamhetsteori/utvecklande arbetsforskning (activity theory/developmental work research: AT/DWR) å ena sidan och datavetenskap (computer science: CS) å den andra. Ett motiv för mitt intresse för objekt i arbete och i programvara, är att bättre förstå problem och möjligheter i ett tvärvetenskapligt forskningsprojekt. Med en början i 2001, startade ett sårvårdsprojekt som ett forsknings- och utvecklingsarbete med den initiala idén att nyttja digitala foton, och snart utvecklades ett informationssystem ("Hedvig") för syftet att hantera digitala foton och annan relaterad behandlingsdokumentation för sårvård. Senare expanderade detta arbetet i skapandet av ett distribuerat informationssystem ("Helar"), en digital prototyp för stöd av sårbehandlingsarbete. Denna avhandling summerar reflektioner relaterade till objektbegreppen. AT/DWR har sin styrka i analys och design av efterfrågad förändring av en arbetspraktik, men är fortfarande svag i metod och tekniker för att stödja skapandet av specifika datorsystem. På ett sätt är det här tillkortakommandet tänkt att balanseras av den teknologiskt datavetenskapliga disciplinen, där en av dess främsta drivkrafter är att utveckla teori och praktik för konstruktion av datoriserade informationssystem. I det tvärvetenskapliga fältet av design av informationssystem för hälso- och omvårdnadsarbete, föreslår denna avhandling fortsatt utveckling av objektkoncepten, och utveckling av de relaterade "scenarios" och "use cases", som ett sätt att dra fördel av en kombination av dessa två olika förtjänster, som de olika disciplinerna står för. objekt, objektorientering, sårvård, digitala foton, verksamhetsteori, datavetenskap, informationssystem

Resumen
Since the HITECH (Health Information Technology for Economic and Clinical Health) Act was enacted, healthcare providers are required to achieve “Meaningful Use.” CPOE (Clinical Provider Order Entry), is one such requirement. Many providers prefer to dictate their orders rather than typing them. Medical vocabulary is wrought with its own terminology and department-specific acronyms, and many ASR (Automated Speech Recognition) systems are not trained to interpret this language. The purpose of this thesis research was to investigate the use and effectiveness of ASR in the healthcare industry. Multiple hospitals and multiple clinicians agreed to be followed through their use of an ASR system to enter patient data into the record. As a result of this research, the effectiveness and use of the ASR was examined, and multiple issues with the use and accuracy of the system were uncovered.

Resumen
The Remote Consultation and Diagnosis (RCD) in Global Picture Archiving and Communication System (Global PACS) is a unique suite of multimedia telemedicine applications developed at the University of Arizona. The applications support real-time patients' data, image files, audio and video consultation and diagnosis annotation exchanges. The RCD enables joint collaboration between pathologists, radiologists, or physicians while they are at distant geographical locations. This project provides four RCD scenarios, i.e., Case Review, Case Acquire, Store and Forward Analysis, as well as Interactive Diagnosis and Consultation. The RCD Global PACS environment consists of heterogeneous, autonomous, and legacy resources. The Common Object Request Broker Architecture (CORBA), Java Database Connectivity (JDBC), and Java language provide the capability to combine the RCD Global PACS resources into an integrated, interoperable, and scalable system. The underneath technology, including IDL, ORB, Event Service, IIOP, JDBC/ODBC, legacy system wrapping and Java implementation are explored. This distributed collaborative CORBA/JDBC based framework will challenge the advanced, medical information management requirements. It also makes the RCD Global PACS both hardware and software technologically independent. As our research and development extend, we will continue to incorporate the latest advances in computer technology. RCD Global PACS is not another new tool in telemedicine, but rather a new paradigm for the delivery of health services that requires process reengineering, cultural changes, as well as organizational changes. It is a whole new way of practicing in telemedicine. We ensure that the RCD Global PACS project has long-term, comprehensive solutions for today and tomorrow's healthcare needs.

Resumen
Medical area has been benefited by the use of ICT (Information and Communication Technology) in recent days. CMIS (Combined Mobile Information System), our proposed model system, is such a system targeted for health care system. IMIS (Integrated Mobile Information System), a system for diabetic healthcare, which is being developed in Blekinge Institute of Technology will be taken as a case study for our proposed system. CMIS is a multi-role system with core service being medical-care related and others like self-monitoring, journal-writing, communicating with fellow patients, relatives, etc. The main reason for not using CMIS could be the security and privacy of the users' information. Any system connected to Internet is always prone to attack, and we think CMIS is no exception. The security and privacy is even more important considering the legal and ethical issues of the sensitive medical data. The CMIS system can be accessed through PDA (Personal Digital Assistant), smart phones or computer via Internet using GPRS (General Packet Radio Service)/UMTS (Universal Mobile Telecommunication System) and wired-communication respectively. On the other hand, it also increases the burden for security and privacy, related to the use of such communications. This thesis discusses various security and privacy issues arising from the use of mobile communication and wired communication in context of CMIS i.e., issues related to GPRS (mobile) and web application (using wired communication). Along with the threats and vulnerabilities, possible countermeasures are also discussed. This thesis also discusses the prospect of using MP2P (Mobile Peer-to-Peer) as a service for some services (for example, instant messaging system between patients) in CMIS. However, our main concern is to study MP2P feasibility with prospect to privacy. In this thesis, we have tried to identify various security and privacy threats and vulnerabilities CMIS could face, security services required to be achieved and countermeasure against those threats and vulnerabilities. In order to accomplish the goal, a literature survey was carried out to find potential vulnerabilities and threats and their solution for our proposed system. We found out that XSS (cross-site scripting), SQL injection and DoS attack being common for a web application. We also found that attack against mobile communication is relatively complex thus difficult to materialize. In short, we think that an overall planned security approach (routinely testing system for vulnerabilities, applying patches, etc) should be used to keep threats and attacks at bay.

Resumen

IMIS (Integrated Mobile Information System for Diabetic Healthcare) aims at providing healthcare on both stationary and mobile platform, which is based on Engström’s triangle model in Activity Theory. It focuses on the need for communication and information accessibility between care-providers and their shared patients. Based on the identified need in the target area, IMIS has decided to construct a network-based communication system to support communication and accessibility to patients’ journal. Since the system integrates various roles from the heath care organization, it is a challenge to provide a useful software program to the group members. In order to facilitate the application and enhance the Human-Computer interaction of the system, agent technology is applied to increase the flexibility factor so that the system could be self-adapted to a wider range group of users.

Besides, this thesis also introduces the approach of using social-psychology — Activity theory in HCI, and discuss the integration of these different disciplines. The Multi-agents System is applied with Gaia methodology from micro perspectives. From the macro perspective Activity theory constructs the coordination mechanism of the different agents. A prototype is applied based on the different model of our research.

Resumen
Computerization has had a large impact on hospital intensive care units, allowing continuous monitoring and display of physiological patient data. Treatment of the critically ill patient, however, now requires assimilating large amounts of patient data.
Computers can help by processing the data and displaying the information in easy to understand formats. Also, knowledge-based systems can provide advice in diagnosis and treatment of patients. If these systems are to be effective, they must be integrated into the total hospital information system and the separate computer data must be jointly integrated into a new database which will become the primary medical record.
This thesis presents the design and implementation of a computerized database for an intensive care unit patient data management system being developed for the Montreal Children's Hospital. The database integrates data from the various PDMS components into one logical information store. The patient data currently managed includes physiological parameter data, patient administrative data and fluid balance data.
A simulator design is also described, which allows for thorough validation and verification of the Patient Data Management System. This simulator can easily be extended for use as a teaching and training tool for PDMS users.
The database and simulator were developed in C and implemented under the OS/2 operating system environment. The database is based on the OS/2 Extended Edition relational Database Manager.

Doctor of Philosophy (PhD)
This thesis describes a study of the utilisation of computers by individual general practitioners (GPs) in Australia, and compares the practice behaviour of GPs who use a computer as a clinical tool, either by prescribing, ordering tests, or storing patient data in an electronic medical record format, with those who do not use a computer for these functions. A survey of individual GP’s use of computers was conducted among 1,336 GPs who participated in the Bettering the Evaluation and Care of Health (BEACH) program between October 2003 and March 2005. The GPs were then assigned to groups according to their clinical use (or not) of a computer, and were compared on a range of variables including the characteristics of the GPs themselves, their practices, their patients, the morbidity they managed for their patients, and the managements they provided. Their behaviour was also compared, using a set of quality indicators designed for use with the BEACH data, and applicable in a primary care setting, to determine whether the clinical use of a computer has an affect on the quality of care GPs provide to their patients. Finally, GPs who use clinical software with embedded pharmaceutical advertising were compared with GPs not exposed to advertisements via this media, to determine whether such advertising influences the prescribing behaviour of GPs to favour advertised brands. From 44 quality indicators examined, clinical computer users performed ‘better’ on four and ‘worse’ on four. For the remaining 36 they exhibited no difference. Exposure to pharmaceutical advertising embedded in clinical software did not influence the prescribing behaviour of the GPs so exposed. Despite the belief espoused in the literature that computer use will improve the quality of patient care, I have found no evidence to demonstrate that the use of a computer for clinical activity has (as yet) affected, either positively or negatively, the quality of care GPs provide to their patients. The current push to computerise general practice will mean that this method of assessment will be difficult to replicate in the future, given the absence of control groups. Other research methods will need to be developed.

Resumen

Implementeringen av ett ERP-system ses inte längre som en ren informations¬teknisk angelägenhet utan en förändring som påverkar hela verksamheten. En implementering, ur vårt perspektiv, är en införandeprocess som har sin början i organisationens motiv till en implementering, valet av system och val av leverantör. Implementeringens omfattning sträcker sig i vår studie till den dag hela systemet tas i bruk. Forskningsfrågor som denna uppsats behandlar är vad som karaktäriserar en implementering av ERP-systemet SAP R/3 samt vad som innefattas i implementeringsbegreppet.

Uppsatsen har utförts genom en komparativ kvalitativ fallstudie där data in¬hämtats genom semistrukturerade intervjuer. Vårt teoretiska fundament utgår ifrån åtta teoretiska sektioner och benämns som ”oktanten”. De områden som ingår i vår oktant är strategi, projekt, process och funktion, standardsystem, organisationsanpassning, systemanpassning, utbildning samt testning och fel¬sökning. Valet av teoretiska aspekter täcker upp de mest väsentliga områden som lämpar sig bäst för vår fokusering av ämnet och bidrar till att besvara vår andra forskningsfråga.

Vi har i denna studie valt att studera hur två organisationers implementering av SAP R/3 har gått till, vad resultatet har varit och varför det blev som det blev. Resultatet, som gäller i båda de studerade fallen, visar att en implementering karaktäriseras av fyra perspektiv som avser strategi, innovation, kommunikation och samarbete. Utöver de karaktäriserande perspektiven utgörs särskilt viktiga aspekter inom processbearbetning.

Resultatet utifrån de fyra perspektiven beskrivs mer utförligt men kortfattat nedan.

Strategi: underskattning av planerad resursförbrukning och överskridande av deadlines samt bristande stöd från ledningen.

Innovation: motiveringssvårigheter vid förändring hos användarna.

Kommunikation: särskilt lyckad placering av projektgrupper på samma geografiska plats.

Samarbete: otillräcklig utbildning och brist på utbildningskompetens, stort supportbehov samt överlåtande av arbetsansvar till konsulter.


Implementing an ERP-system is no longer considered an information technology concern purely but a change affecting the whole organization. An implementation is, by our definition, an initiation process starting with the motives of the organization to execute the implementation, choice of system and choice of vendor. The scope of the implementation, in our study, stretches until the day the system goes live. This thesis attends following research questions: what characterises implementation of the ERP-system SAP R/3 and what is included in the concept of implementation?

The thesis has been performed through a comparative qualitative case study where data has been collected during semi-standard interviews. Our theoretical foundation is divided into eight sectors forming an octant all together. Areas composing our octant are strategy, project and function, standard system, organizational adoption, system adoption, education and testing and error detection. The choice of theoretical aspects covers the most vital areas suitable for our focus on the subject and contributes to answering our second research question.

In this study we have chosen to examine the process of two organizations implementations of SAP R/3, the outcome and why it resulted in the way it did.

The result shows that, for both cases, a implementation is characterised of four perspectives concerning strategy, innovation, communication and cooperation. In addition to the characterised perspectives certain aspects of process re-engineering are particularly important.

The result out of the four perspectives is more detailed but briefly describes bellow.

Strategy: underestimation in consumption of resources and exceeding deadlines along with lack of top management support

Innovation: difficulties motivating users for the change.

Communication: exceptional success in placing members of the projects at same geographical location.

Cooperation: insufficient level of education, lack of educational competence, great need of support and responsibility of work delegated to consultants

Resumen
This thesis presents the design and implementation of a Nursing Workload Manager module for a Patient Data Management System in an intensive care unit. The Nursing Workload Manager aids in the planning and documentation of the nurse's workload. It automates the generation of the nursing care plan and automatically assigns a score to the care plan based on a nursing workload measurement system.

Resumen
This research investigated the question of whether automatic or system-generated information classification methods can help humans better manage information. A series of four experiments were conducted; they investigated the usability (i.e., usefulness) of two automatic approaches to information classification, the concept space approach and a Kohonen-based SOM approach in the context of information retrieval. The concept space approach was evaluated in three different domains: Electronic Brainstorming (EBS) sessions, the Internet, and medical literature (the CancerLit collection). The Kohonen-based SOM approach was evaluated in the Internet and medical literature (CancerLit) domains only. In each case, the approach under investigation was compared with existing systems in order to demonstrate performance viability. The basic premise that information management, in particular information retrieval, can be successfully supported by system-based information classification techniques and that humans would find such techniques viable and useful was supported by the experiments. The concept space approach was more successful than the Kohonen-based SOM approach. After modifications to the algorithms based on user feedback from the EBS experiments had been made, users found the concept space approach results to be comparable (in the Internet study) or superior (in the CancerLit study) to existing information classification systems. The key future enhancement will be incorporation of better ways to identify document descriptors through syntactic and semantic front-end processing. The Kohonen-based SOM approach was considered difficult to use in all but one specialized case (the dynamic SOM created as part of the CancerLit prototype). This can probably be attributed to the fact that its associative organization does not match with the standard mental models (hierarchical and alphabetic) for information classification.

Resumen
With the increasing elderly population and longer life expectancies, smart wearable technologies are playing an important role in facilitating caregivers to monitor elderly people remotely. Aifloo’s wristband is one smart wristband which can collect various data, predict activities and detect abnormalities to enable elderly people to live independently at home. However, too much information and poor visualizations will cause huge difficulties for caregivers to interpret the data. Six caregivers were interviewed in this study to investigate what data is relevant to monitor elderly people and how they interpret the different designed displays. The main results show that alarms, fall incidents and medication compliance are the most important. Besides, caregivers place a greater emphasis on holistic views of data and they want to highlight abnormal behaviors and alerts. In the end, design guidelines for the information system to present data meaningfully and intuitively are generated.
Med ett ökande antal äldre och en ökande medellivslängd kommer smart, bärbar teknologi att spela en större roll i äldrevården för att övervaka de äldre. Aifloos armband är en smart teknologi som kan samla in olika former av data, förutsäga aktiviteter och upptäcka avvikande och onormala beteenden, vilket kan användas av äldre som bor självständiga i sena egna hem. Stora mängder data, och dåliga visualiseringar av dem, orsakar svårigheter för vårdgivare att tolka datan. I den här studien har sex vårdgivare intervjuats för att utforska vilken data som är relevant för dem, och hur de kan tolka information ifrån en grupp olika gränssnitt. Studiens resultat visar att alarm, fallolyckor och översikt över hur de äldre efterföljer sina medicinska recept är viktigast. Vårdgivarna lägger en större vikt vid att förstå datan holistiskt, och de vill synliggöra avvikande beteendemönster och varningar. Slutgiltligen presenteras riktlinjer för hur IT-system kan designas för att presentera data på ett meningsfullt och intuitivt vis.

Resumen
Recent advances in information and communication technologies have made the development and operation of complex disease surveillance systems technically feasible, and many systems have been proposed to interpret diverse data sources for health-related signals. Implementing these systems for daily use and efficiently interpreting their output, however, remains a technical challenge. This thesis presents a method for understanding disease surveillance systems structurally, examines four existing systems, and discusses the implications of developing such systems. The discussion is followed by two papers. The first paper describes the design of a national outbreak detection system for daily disease surveillance. It is currently in use at the Swedish Institute for Communicable Disease Control. The source code has been licenced under GNU v3 and is freely available. The second paper discusses methodological issues in computational epidemiology, and presents the lessons learned from a software development project in which a spatially explicit micro-meso-macro model for the entire Swedish population was built based on registry data.

Resumen
Due to a rapid increase in aging population, demand for personalized health care increases proportionally. Personalized patient data can be a helpful way of catering the needs and requirements of elderly people staying at home. Indirectly, it can be a manner of providing better eHealth services according to their needs. Another interesting aspect of providing better personalized eHealth services is to make patient information systems interoperable. Interoperability of eHealth systems is an issue of great concern to current research and development but in this study, we focus on patient information systems. Like in some other European countries, introduction of open source platform to achieve interoperability and personalization of patient information system could save money for health care organizations and make the procedure easier in Sweden also. The purpose of this study is to identify what standards are available for interoperability and what are the benefits and challenges of introducing open source systems for achieving personalized interoperable patient information systems (PIPIS). In light of this investigation, author has identified the benefits and challenges of introducing OSS for achieving PIPIS. Author has also made several recommendations regarding the challenges identified.
In the name of ALLAH, the most gracious and merciful. I extend my gratitude to the beautiful creator of this beautiful universe that He made for us to conquer. Without the love of my parents this thesis report could never be possible for me to write. All my love and care is for them which no one else can share. I thank Mr. Hans Kyhlbäck whose supervision is a source of inspiration for doing this study. He is definitely the best supervisor to work with. In the end, I would like to thank my friends and colleagues whose help just kept me going despite of many hurdles that I faced.

Resumen
Africa has been seeing a steady increase in the Information and Communication Technology (ICT) systems deployed in health care institutions. This is evidenced by the funding that has been going into health information systems from both the government and the donor organisations. Large numbers of national and international agencies, research organisations, Non- Governmental Organisations(NGOs) etc continue to carry out studies and develop systems and procedures to exploit the power of Information and Communication Technology (ICT) in public and private health institutions. This uncoordinated mass migration to electronic medical record systems in Africa has created a heterogeneous and complex computing environment in health care institutions, where most of the deployed systems have technologies that are local, proprietary and insular. Furthermore, the electronic infrastructure in Africa meant to facilitate the electronic exchange of information has a number of constraints. The infrastructure connectivity on which ICT applications run, is still segmented. Most parts of Africa lack the availability of a reliable connectivity infrastructure. In some cases, there is no connectivity at all. This work aims at using Service Oriented Architectures (SOA) to address the problems of interoperability of systems deployed in Africa and suggest design architectures that are able to deal with the state of poor connectivity. SOA offers to bring better interoperability of systems deployed and re-usability of existing IT assets, including those using different electronic health standards in a resource constrained environment like Africa.

Resumen
39 million people in the world are blind and approximately 15 million of them live in India. Aravind Eye Care System is the biggest provider of eye care in India and the world and it continues to expand and spread medical understanding and best practice to improve ophthalmological care. Aravind Hospitals measure data of performance indicators for management and identify best practice. Currently, each department handles data of these parameters in locally stored excel sheets which limiting benchmarking in real-time. The main objective of this project has been to develop a user-friendly web platform that enables real time benchmarking across all of Aravind’s hospitals. A prototype of a web based business intelligence system has been developed as a proof of concept. The aim of this prototype has been to enable benchmarking across Aravind’s hospitals. The impact has been studied to analyse the extents to which the organization can become more efficient through continuous benchmarking. Initially, a database was developed containing data from the glaucoma clinics in Coimbatore, Madurai, Pondicherry and Tirunelveli. Subsequent was a web platform developed which presents the data dynamically with Google Charts. Interviews and analyses support the implementation of a business intelligence system at Aravind’s Hospitals. Testing and analysis have proven that a business intelligence system can improve value, create innovation and spread best practice at Aravind’s Hospitals.
39 miljoner personer i världen är blinda och uppskattningsvis 15 miljoner av dem bor i Indien. Aravind Eye Care System är de största leverantörerna av ögonsjukvård i Indien och i världen. De fortsätter att växa och sprida medicinsk kunskap och best practice för att förbättra ögonsjukvården. Aravinds sjukhus mäter data på nyckelparametrar av verksamheten för management och för att identifiera best practice. För närvarande så hanterar varje avdelning data av dessa parametrar i lokalt lagrade Excel dokument vilket begränsar benchmarking i realtid. Det huvudsakliga syftet med detta projekt har varit att utveckla en användarvänlig web plattform som möjliggör benchmarking mellan Aravinds sjukhus i realtid. En prototyp av ett web baserat business intelligence system har utvecklats i form av ett proof of concept. Syftet med denna prototyp har varit att möjliggöra benchmarking mellan Aravinds sjukhus. Dess påverkan har utvärderats och analyserats för att studera till vilken utsträckning organisationen kan bli mer effektiv genom kontinuerlig benchmarking. Till en början har en databas utvecklats för att hantera data från glaukom klinikerna i Coimbatore, Madurai, Pondicherry and Tirunelveli. Där efter har en web plattform utvecklats som presenterar dynamisk data med Google Charts. Intervjuer och analyser stödjer implementationen av ett business intelligence system på Aravinds sjukhus. Denna rapport har bevisat att det är genomförbart att utveckla en skalbar open-source webbplattform som möjliggör benchmarking i realtid. Tester och analyser har även visat att ett business intelligence kan vara värdeskapande, innovation skapande samt sprida kunskap på Aravinds sjukhus.

Resumen
Biometrics Technology is an authentication technology that identifies the individuals from their physical and behavioral characteristics. Despite the fact that biometrics technology provides robust authentication and enhanced security, it has not yet been implemented in many parts of the world due to certain issues i.e. human perceptions of the biometrics technology and cost factor, involved in the deployment of biometrics technology. As the biometrics technology involves identity management of individuals that’s why the humans perceptions of biometrics technology i.e. privacy concerns, security concerns and user acceptance issue play a very important role in the deployment of biometrics technology. There for the human perceptions and cost factor need to be considered before any deployment of biometrics technology. The aim of this thesis work is to study and analyze how the people’s perceptions and cost factor can be solved for the deployment of biometrics technology in Blekinge health care system. Literature study, interviews and survey are performed by authors for the identification and understanding of the human perceptions and cost factor. Based on these, solutions in form of guidelines to the issues involved in the biometrics technology deployment in Blekinge health care system Sweden are given.
Biometri Teknik är en autentisering teknik som identifierar individer från deras fysiska och beteendemässiga egenskaper. Trots att biometriska tekniken ger en robust autentisering och ökad säkerhet, har det ännu inte genomförts i många delar av världen på grund av vissa frågor som exempelvis mänskliga uppfattningar om biometriska tekniken och extra kostnader, som deltar i användningen av biometriska tekniken. Eftersom biometriska tekniken innebär identitetshantering av individer som är anledningen till att människor uppfattningar av biometriska tekniken dvs rör skyddet av privatlivet, säkerhetsfrågor och användarnas inställning fråga spelar en mycket viktig roll i spridningen av biometriska tekniken. Där för människors uppfattningar och kostnad faktor måste beaktas innan en eventuell utplacering av biometriska tekniken. Syftet med detta examensarbete är att studera och analysera hur människors uppfattning och kostnad faktor kan lösas för införande av biometri teknik i Blekinge hälsovårdssystemet. Litteraturstudie, intervjuer och undersökningar utförs av författare för identifiering och förståelse av människans förnimmelser och kostnad faktor. Baserat på dessa, är lösningar i form av riktlinjer för de frågor som berörs av biometri spridningen av tekniken i Blekinge sjukvårdssystem Sverige ges.

Resumen
The benefits of using electronic medical records (EMRs) have been well documented; however, despite numerous financial benefits and cost reductions being offered by the federal government, some healthcare professionals have been reluctant to implement EMR systems. In fact, prior research provides evidence of failed EMR implementations due to resistance on the part of physicians, nurses, and clinical administrators. In 2010, only 25% of office-based physicians have basic EMR systems and only 10% have fully functional systems. One of the hindrances believed to be responsible for the slow implementation rates of EMR systems is resistance from healthcare professionals not truly convinced that the system could be of substantive use to them. This study used quantitative methods to measure the relationships between six constructs, namely computer self-efficacy (CSE), perceived complexity (PC), attitude toward EMR (ATE), peer pressure (PP), anxiety (AXY), and resistance to use of technology (RES), are predominantly found in the literature with mixed results. Moreover, they may play a significant role in exposing the source of resistance that exists amongst American healthcare professionals when using Electronic Medical Records (EMR) Systems. This study also measured four covariates: age, role in healthcare, years in healthcare, gender, and years of computer use. This study used Structural Equation Modeling (SEM) and an analysis of covariance (ANCOVA) to address the research hypotheses proposed. The survey instrument was based on existing construct measures that have been previously validated in literature, however, not in a single model. Thus, construct validity and reliability was done with the help of subject matter experts (SMEs) using the Delphi method. Moreover, a pilot study of 20 participants was conducted before the full data collection was done, where some minor adjustments to the instrument were made. The analysis consisted of SEM using the R software and programming language. A Web-based survey instrument consisting of 45 items was used to assess the six constructs and demographics data. The data was collected from healthcare professionals across the United States. After data cleaning, 258 responses were found to be viable for further analysis. Resistance to EMR Systems amongst healthcare professionals was examined through the utilization of a quantitative methodology and a cross-sectional research measuring the self-report survey responses of medical professionals. The analysis found that the overall R2 after the SEM was performed, the model had an overall R2 of 0.78, which indicated that 78% variability in RES could be accounted by CSE, PC, ATE, PP, and AXY. The SEM analysis of AXY and RES illustrated a path that was highly significant (β= 0.87, p < .001), while the other constructs impact on RES were not significant. No covariates, besides years of computer use, were found to show any significance differences. This research study has numerous implications for practice and research. The identification of significant predictors of resistance can assist healthcare administrators and EMR system vendors to develop ways to improve the design of the system. This study results also help identify other aspects of EMR system implementation and use that will reduce resistance by healthcare professionals. From a research perspective, the identification of specific attitudinal, demographic, professional, or knowledge-related predictors of reference through the SEM and ANCOVA could provide future researchers with an indication of where to focus additional research attention in order to obtain more precise knowledge about the roots of physician resistance to using EMR systems.

Resumen
Electronic Dental Records (EDR) are an important part of dental care in Sweden. The usability of these records can affect the workflow in dental care organizations. This study aims to measure the System usability scale (SUS) score of EDRs that are used in dental clinics in Sweden. The study will also investigate the relationship between the SUS score of EDRs and participants’ age, gender, interest in technology, number of patients per workday, professional experience, possible special training to use the EDR, and the period of the training. The study will also rank the most common usability problem in EDRs among the seven possible usability problems included in the questionnaire. The study will present how the participants describe experienced usability problems in the EDRs. The quantitative method constitutes the largest part of this study, while the open-ended questions were used to get a deeper knowledge about some of the usability problems. A digital questionnaire was used in this study to gather data from 115 dentists and 77 dental hygienists who work at various dental clinics around Sweden to get a statistical anchored description about the usability of various EDRs. SUS indicates a low usability level in the EDRs included in the study and a significant negative correlation between the frequency of using EDRs and usability. The males showed better experience with the usability of the EDRs compared to females. The highest-ranked usability problem was the need for users to spend a long time to document patient cases. The usability problems were summarized into three categories which are: an inefficient user interface, lack of semantic interoperability, and users relying on paper.
Elektroniska journalsystem är en viktig del av tandvården i Sverige, då användbarheten av dessa system kan påverka arbetsflödet i tandvårdsorganisationer. Denna studie syftar till att mäta System usability scale (SUS) poäng för olika elektroniska journalsystem som används i olika tandkliniker i Sverige. Studien kommer också att undersöka sambandet mellan SUS-poäng för elektroniska journalsystem och deltagarnas ålder, kön, intresse av teknologi, antal patienter per arbetsdag, yrkeserfarenhet, möjlig specialutbildning för att använda elektroniska journalsystem och perioden för denna utbildning. Studien kommer också att rangordna det vanligaste användbarhetsproblemet i journalsystem bland de sju möjliga användbarhetsproblemen som ingår i frågeformuläret. Studien kommer att presentera hur deltagarna beskriver upplevda användbarhetsproblem i journalsystem. Den kvantitativa metoden utgör den största delen av denna studie, medan de öppna frågorna användes för att få en djupare kunskap om några av användbarhetsproblemen. Ett digitalt frågeformulär användes i denna studie för att samla in data från 115 tandläkare och 77 tandhygienister som arbetar vid olika tandkliniker runt om i Sverige för att få en statistisk förankrad beskrivning om användbarheten av olika elektroniska journalsystem. SUS indikerar en låg användbarhetsnivå i de systemen som ingår i studien. Vi upptäckte också en signifikant negativ korrelation mellan frekvensen av att använda systemen och användbarhetsnivån. Män visade en bättre upplevelse för användbarhet av systemen jämfört med kvinnor. Det högst rankade användbarhetsproblemet var användarnas behov av lång tid för att dokumentera patientfall. Vi sammanfattade hur deltagarna beskriver upplevda användbarhetsproblem i journalsystem under tre kategorier som är: ett ineffektivt användargränssnitt, brist på semantisk interoperabilitet och användare som skriver på en lapp.

Thesis (MTech (Information Technology))--Cape Peninsula University of Technology, 2012.
This research is an attempt to investigate the utilisation of Information Communication Technology (ICT) in Healthcare to support the flow of HIV/AIDS patient’s general information in public and private sector. Furthermore, the research examines the detail flow of database information for healthcare service delivery to patients, in particular HIV/AIDS patients, in Khayelitsha Township. Finally, the research will detail the types of technologies currently being utilised to transfer this information, technology utilised for capturing or data collection profile of the patient. The research study data collecting was done in 2009 in mostly private and public healthcare centre in Khayelitsha township. First, the study will concentrate on general utilisation of ICT in healthcare service delivery and flow of information for public and private sector healthcare centres. Additionally, the research also looks at NGOs such as HIV/AIDS Unit in Cape Peninsula University of Technology (CPUT) and Treament Action Campaign (TAC) to find out what ICT equipment is being utilised to transfer this information to adult people to inform and make them to be aware of HIV/AIDS and improve healthcare service delivery to patients and particularly to HIV/AIDS patients. Taking NGO’s such as TAC and CPUT HIV/AIDS Unit that are well informed about HIV/AIDS, nationally and internationally will make our research results to be more precise. The research will also look at the utilisation of ICT in flow of information at healthcare centre such as communication between healthcare providers such as receptionist/clerk, nurses, doctors and medical researchers since they are the first people who deal with HIV/AIDS patient cases when they come for healthcare provision.

Resumen
Digital services involving large systems with multiple users are ubiquitous in modern society. The systems are often complicated and made up of multiple devices and communication protocols. A fundamental problem in this context is how the behavior of a system changes as the number of users vary. In particular, when do the systems’ resources saturate and how does the system behave when close to saturation. Performance testing is key for addressing this fundamental problem. Performance testing is the scope of this project. Performance tests can be used for inference of, for example, a system's scalability. Furthermore, it can be used to provide general guarantees on the services that can be delivered. Performance testing at the company Phoniro AB is considered. The platform Phoniro Care is the back-end service for the company’s products. The Phoiro 6000 system is one of the products that uses Phoniro Care. The system allows for multiple users and offers alarm services. The primary focus of this project is to determine the behavior of that system during varying levels of simulated load, and furthermore analyze the data extracted from such simulations and tests. The open source software JMeter was used as the tool for performance testing. It was selected from a set of candidate tools that have been evaluated in the literature based on various performance criteria. The results are presented by graphs showing the time evolution of different performance indicators. A conclusion from this work is that the implemented performance testing framework helps to answer questions about the systems’ behavior. Questions that are important for the company’s further development and expansion of the system. Furthermore, the proposed framework establishes a foundation for further inquiries on the subject.

Resumen
In 2010 the new Swedish national system for health care 1177.se was launched in order for users to have one place where to find health care related information. The primary stakeholders of this system, which is online based, are the counties and regions of Sweden. The purpose of the thesis is to identify what improvements can be made on the health care system in order to benefit new technologies and in the end the users. The main question that the thesis will address is: * How can a PACT analysis improve the design of health the health care system 1177.se to benefit new technologies in order to be as available as possible. The method that has been used in order to gain knowledge in the subject has been literature studies, observations, scenario building and also an interview. The analysis of the empirical and theoretical studies has shown that more attention should be placed on people that have different disabilities and people with other origins then Sweden. People that are not so comfortable with Internet technology also is a group of people that needs to be placed in focus.
1177.se är det nya svenska informationssystemet för vård som lanserades 2010. Initiativtagarna är regioner och landsting i Sverige. Målet med 1177.se är att den ska bli den ledande resursen för de svenska invånarna när det kommer till information och råd om hälsa, sjukvård och tandvård. Det senaste decenniet har Internet utvecklats så pass mycket att vården kan använda dess kapacitet för invånarna i Sverige. Regionerna och landstingen såg en möjlighet att använda en gemensam plats för alla invånare att hitta information om hälsa, sjukvård och tandvård. Sverige har ungefär 9,5 miljoner invånare (SCB, 2011) som alla vid någon tidpunkt kommer i kontakt med det svenska sjukvårdssystemet. De kan lida av alla från sorters sjukdomar till att enbart söka information eller hitta information om vård i närområdet och leta efter fakta själva. Det finns flera olika användningsområden för informationssystemet 1177.se vilket betyder att hur man designar systemet är av yttersta vikt. En PACT (People, Activities, Contexts, Technologies) analys strävar mot att identifiera vilka olika aktiviteter som människor gör och i vilka kontexter samt vilken teknik man använder för att ge en indikation på vad man bör tänka på då ett informationssystem designas. Denna uppsats är ett försök att analysera informationssystemet 1177.se och ge min syn på vilka förbättringar som kan göras efter att ha gjort en PACT analys.

This thesis examines the problems related to IT in the Swedish healthcare system, specifically the drug searching part of the electronic healthcare systems used in Sweden. The question formulation is divided into two questions: What parameters and functions are of greatest importance when performing a search on drugs, and how should these be presented in a graphical user interface? Thus the purpose is to answer these questions through developing a design concept, in the form of a prototype, which describes how a drug search can be carried out.

The entry point is a central quality checked drug database that is managed and owned by Swedish county councils and regions. The problem is attacked through user-centered methods where interviews of physicians and developers, in conjunction with observations, are used to give an overview of the problem area as well as to specify a requirements specification for the prototype that this thesis aims to develop. The thesis result is a requirements specification in combination with a prototype that exemplifies how drug searching can be performed, the prototype is based the requirements gathered from the interviews with the user group of physicians.


Den här uppsatsen behandlar problematiken kring IT i vården och mer specifikt läkemedelssökningar i vårddokumentationssystem. Frågeställningen är uppdelad i två frågor: Vilka parametrar och funktioner är av störst vikt vid en sökning på läkemedel samt, hur bör dessa presenteras i det grafiska gränssnittet? Syftet är därav att besvara dessa frågor genom ett designkoncept, i form av en prototyp, som beskriver hur en läkemedelssökning kan gå till.

Ingångspunkten är en centralt kvalitetssäkrad läkemedelsdatabas som förvaltas av en organisation som ägs av Sveriges landsting och regioner. Problemet angrips med hjälp av användarcentrerade metoder där intervjuer av läkare och utvecklare används, tillsammans med observationer, för att ge en bild av problemområdet samt för att ställa upp krav på den prototyp som denna uppsats ämnar framta. Uppsatsens resultat är en kravspecifikation i kombination med en prototyp för hur läkemedelssökning kan gå till baserat på krav extraherade ur intervjuer med en användargrupp bestående av läkare.

Resumen
This paper deals with medical data extraction from electronic patient record (EPR) system. Most of the medical data are stored in patient record systems, and data that are much valuable for medical research. If a researcher wants to extract medical information today, it has to be done manually because the data are stored in unstructured textual format in a system created by hospital staff. There is no way of extracting data in structure way. This paper is going to introduce an information extraction application for EPR system that allows the researcher to set up a study with inclusion and parameters for extraction for retrospective surveys in a webuser-interface environment. Inclusion is what the researcher would like to study (a defined category or criteria) and parameters specify the characteristics of inclusion the criteria. Result of this application provides an extracted clinical data that is used for retrospective surveys, downloadable to an MS-Excel file.

Resumen
In developing countries, acute respiratory infections (ARIs) are responsible for two million deaths per year. Most victims are children who are less than 5 years old. Pneumonia kills 5000 children per day. The statistics for cardiovascular diseases (CVDs) are even more alarming. According to a 2009 report from the World Health Organization (WHO), CVDs kill 17 million people per year. In many resource-poor parts of the world such as India and China, many people are unable to access cardiologists, pulmonologists, and other specialists. Hence, low skilled health professionals are responsible for screening people for ARIs and CVDs in these areas. For example, in the rural areas of the Philippines, there is only one doctor for every 10,000 people. By contrast, the United States has one doctor for every 500 Americans. Due to advances in technology, it is now possible to use a smartphone for audio recording, signal processing, and machine learning. In my thesis, I have developed an Android application named Smart Auscultation. Auscultation is a process in which physicians listen to heart and lung sounds to diagnose disorders. Cardiologists spend years mastering this skill. The Smart Auscultation application is capable of recording and classifying heart sounds, and can be used by public or clinical health workers. This application can detect abnormal heart sounds with up to 92-98% accuracy. In addition, the application can record, but not yet classify, lung sounds. This application will be able to help save thousands of lives by allowing anyone to identify abnormal heart and lung sounds.

Resumen
Health care systems in many countries are experiencing a growing demand while their resources remain limited. The discrepancy between demand and capacity creates many problems – long waiting times for treatment, overcrowding in hospital wards, high workload, etc. More efficient delivery of health care services can be achieved by better planning of its resources so that the mismatch between demand and capacity is minimized. Planning health care resources, including hospital resources, is difficult due to system complexity and variability in both resource availability and demand. Discrete-event simulation and other operational research methods can be used for solving planning problems in health care, and have been gaining increased attention from researchers during recent decades. Despite the growing number of academic publications, simulation appears to be less used in health care than in other application areas and only a small proportion of simulation studies is actually implemented. The aim of this thesis is to contribute to increased use of discrete-event simulation in hospital resource planning. The separate studies regarding intensive care unit capacity planning, operating room allocation strategies and the management of emergency patient flow in a radiology department highlight both the possibilities and the requirements for practical application of discrete-event simulation in hospital resource planning. The studies are described in five papers. In the first paper, the relationship between intensive care unit (ICU) occupancy and patient outcomes was investigated and the results showed that risk adjusted mortality was higher in the group of patients who were treated during high levels of occupancy. This indicates that appropriate planning of ICU resources is necessary to avoid adverse effects on patient outcomes. In the second paper, analysis of a relatively simple care chain consisting of two hospital departments – emergency and radiology – revealed a process that was not very well defined and measured. Investigation into data availability uncovered disparate information systems storing incompatible and fragmented data. It suggests that the current degree of process orientation and the current IT infrastructure does not enable efficient use of quantitative process analysis and management tools such as simulation. In the third paper, the value and possibilities of using simulation modelling in hospital resource planning were examined through the development and use of a simulation model for improved operating room time allocation and patient flow in a hospital operating department. The model was initially used for studying overcrowding in a post-anaesthesia care unit. Advanced planning logic implemented in the model enabled evaluation of several different scenarios aiming to improve the utilization of operating room resources. The results showed that it is possible to achieve slightly better and more even resource utilization, as well as provide greater flexibility in scheduling operations. In the fourth paper, a generic ICU model was developed and validated using data from four different hospital ICUs. The model was adapted and calibrated stepwise in order to identify important parameters and their values to obtain a match between model predictions and actual data. The study showed that in presence of high quality data and well defined process logic it is possible to develop a generic ICU simulation model that could provide accurate decision support for planning critical care resources. In the fifth paper, a number of factors that can contribute to successful implementation of simulation results in health care were identified. The timing of the simulation study must be right to support a critical decision, the benefit from implementation should clearly outweigh the cost of making the necessary changes and the model should be thoroughly validated to increase the credibility of the results. Staff involvement in simulation modelling activities, availability of good quality data, as well as proper incentives to improve the system contribute to implementation as well. These findings can help in establishing the conditions for successful implementation in future applications of simulation modelling in health care.
Hälso- och sjukvårdssystemen i många länder möter en växande efterfrågan samtidigt som resurserna är begränsade. När efterfrågan överstiger kapaciteten skapas många problem, bland annat långa väntetider för behandling, överbeläggningar i sjukhusavdelningar och hög arbetsbelastning för personalen. En effektivare sjukvård kan uppnås genom bättre planering av resurserna, så att obalansen mellan efterfrågan och kapacitet minimeras. Planering av hälso- och sjukvårdsresurser, inklusive sjukhusresurser, är svårt på grund av systemkomplexitet och variation i både resurstillgänglighet och efterfrågan. Simulering och andra operationsanalytiska metoder som används för att lösa planeringsproblem inom tillverkning, logistik och andra områden, kan med fördel användas också inom sjukvården och har fått ökad uppmärksamhet av forskare under de senaste årtiondena. Trots det växande antalet akademiska publikationer verkar simulering användas betydligt mindre inom sjukvården än i andra tillämpningsområden och endast en liten del av resultaten omsätts i praktiken. Syftet med denna avhandling är att bidra till ökad användning av simulering vid planering av sjukhusresurser. De separata studierna i avhandlingen behandlar kapacitetsdimensionering av intensivvård, allokering av operationssalsresurser samt hantering av akutpatientflödet på en röntgenavdelning, och lyfter därigenom fram både möjligheterna och kraven för praktisk tillämpning av diskret händelsesstyrd simulering för planering av sjukhusresurser. Intensivvårdsavdelningar anses vara bland de dyraste resurserna på ett sjukhus. Det är därför ekonomiskt önskvärt att ha en hög utnyttjandegrad av en sådan resurs. Samtidigt är det viktigt att alltid ha utrymme för kritiskt sjuka patienter. I en studie där förhållandet mellan beläggningen på intensivvårdsavdelningar och patientutfall undersöktes visade resultaten att riskjusterad dödlighet var högre för patienter som behandlades när beläggningen på avdelningen var hög, vilket understryker att bra planering av intensivvårdsresurser är mycket viktigt. Hög grad av processorientering och tillgång till data som möjliggör undersökning av patientflödet över gränserna av sjukhusets organisatoriska och funktionella enheter är exempel på förutsättningar för användning av simulering för hela vårdkedjor. En analys av en relativt enkel vårdkedja bestående av två sjukhusavdelningar avslöjade dock en process som inte var särskilt väldefinierad, och där olika informationssystem lagrade inkompatibla och fragmenterade data. Avsaknaden av processorientering och den befintliga IT-infrastrukturen är hinder för effektiv användning av kvantitativa processanalysverktyg som simulering. Värdet av att utnyttja simulering och modellering för planering av sjukhusresurser användes vidare för att hitta en bättre och jämnare fördelning av operationssalsresurser. Modellen användes för att undersöka ett antal scenarier och resultatet visade att det är möjligt att uppnå ett jämnare utnyttjande av operationssalar och en större flexibilitet vid schemaläggning av operationer. Generiska simuleringsmodeller, som med hjälp av ett antal parameterinställningar kan omvandlas till en ny modell av en given sjukhusenhet, skulle sannolikt öka användningen av simulering. Dock kan det vara svårt att visa hur dessa modeller avbildar varje specifik enhet på ett tillräckligt trovärdigt sätt. En generisk modell för kapacitetsdimensionering av intensivvårdsavdelningar har utvecklats och validerats med hjälp av data från fyra olika sjukhus. Studien visade att när data är av hög kvalitet och processlogiken är väldefinierad är det möjligt att utveckla en sådan generisk simuleringsmodell som kan ge beslutsstöd vid planering av intensivvårdsresurser. Flera litteraturundersökningar har visat att endast en liten del av publicerade simuleringsstudier inom sjukvården har implementerats. Genom att studera ett flerårigt simuleringsprojekt identifierades ett antal faktorer som kan bidra till att simuleringsresultat faktiskt används för att förändra verksamheten. Tidpunkten för simuleringsstudien måste vara välanpassad för att stödja ett kritiskt beslut, fördelar med förändringen bör tydligt överväga kostnaden för att genomföra den och modellen bör grundligt valideras för att öka resultatens trovärdighet. Personalens engagemang i modelleringsaktiviteter, tillgång till data av god kvalitet samt lämpliga incitament för att förbättra systemet bidrar också till genomförandet. Resultaten kan hjälpa till att skapa förutsättningar för framgångsrik framtida användning av simulering vid planering av sjukhusresurser.

Resumen
During the last decade, electronic prescribing has been a point of focus in healthcare industry and is rapidly becoming a standard of practice. It has proven as an important element in improving the quality of patient care, mitigating or eliminating the phone calls back and forth from pharmacies to point of care/health centers. Many e-prescribing systems were developed and marketed but these usually were unsuccessful because of the lack of direct electronic connectivity to local pharmacies and the lack of up-to-date formulary information, clinical guidelines, health plans & services among other reasons. Despite their benefits, the adoption and usage of electronic prescribing systems has been low. In some of the developing countries like Uganda, the problem is even worst. Due to lack of essential resources and manpower, healthcare services have significantly impacted on the productivity and quality of patient care.In an effort to improve, promote and maintain the quality of health services in rural settings of developing countries like Uganda, a high level design for e-prescribing system has been proposed. Design specifications for Electronic Prescribing Management System (EPMS) along with functional prototype are built based on ICT4MPOWER project requirements and previous research and publications in this area.Initially research began with Drug and Stock Management System and EPMS emerged as one of its essential components. In order to strengthen and establish connection between ongoing electronic health record system and drug and stock management development, EPMS component came into lime light. Mare prescription management is not enough to serve patient centric needs. Hence, clinical decision support has been introduced into e- prescribing system to improve the quality of prescribing decisions. In order to develop a patient-centric e-prescribing system that is self-evolving and self sustaining, it is important to update the clinical decision-support system, formularies & guidelines on regular basis. In order to make it usable, it is required to formulate effective health plans and increase associations between pharmacies and other health organizational units. The principal benefit of introducing E-prescribing system into Electronic Health Record (EHR) System is to connect open ended systems to form a strong knowledge base for future.
