Повний текст джерелаIn the Western Cape, South Africa, despite the prospective benefits that e-Health information systems (e-Health IS) offer to support the healthcare sector; there are limitations in terms of usability, functionality and peculiar socio-technical factors. Thus, healthcare professionals do not make the most use of the implemented e-Health IS. Unfortunately, explanations remain tentative and unclear, yet non-usage of the e-Health IS defeats the objectives of its adoption, in the sense that the plan to improve and deliver quality healthcare service in the public sector may not be achieved as envisaged. The aim of the study was to acquire explanations to the causes of the limitations regarding the adoption and, particularly, the use (or non-use) of e-Health IS by clinical staff in the public healthcare institutions in South Africa. The choice of research approach was informed by the research problem, objectives, and the main research question. By the reasons of the subjective and socio-technical nature of the phenomenon, a deductive approach was adopted for this investigation. The nominalist ontology and interpretivist epistemology positions were taken by the researcher as a lens to conduct this research; which informed a qualitative methodology for this investigation. The purposive sampling technique was used to identify the appropriate participants from different hospital levels consisting of Hospital Administrative staff, and Clinical staff (Clinicians and Nurses) of relative experiences in their clinical units. Subsequently, the Unified Theory of Acceptance and Use of Technology (UTAUT) and content analysis technique were used to contextualize, simplify, and analysis the text data transcripts. The findings indicate that healthcare professionals have a high level of awareness and acceptance to use implemented e-Health IS. There are positive perceptions on the expected outcomes, that e-Health IS would improve processes and enhance healthcare services delivery in the public healthcare sector. Also, findings indicate that social influence plays a vital role especially on the willingness of individuals (or groups); as the clinical staff are influenced by their colleagues despite the facilitating conditions provided by the hospital management. Further, findings indicate that it is somewhat problematic to maintain balance in running a parallel paper-electronic system in the hospital environment. Hence, the core factors that influence successful adoption and use of e-Health IS include; willingness of an individual (or group) to accept and use a technology, the performance expectancy, social influence among professionals in the healthcare scenery and adequate facilitating conditions. In summary, it is recommended that there should be an extensive engagement inclusive of all respective stakeholders involved in the adoption processes. This would ensure that e-Health IS are designed to meet both practical organizational and clinical needs (and expectations) with respect to the hospital contexts.

Повний текст джерелаUnlike the developed nations, the health sector within the developing countries is faced with the triple challenges of human, financial and technological scarcity of resources. This insufficiency of resources results into amongst other intrapartum mishaps. To ameliorate some of these conditions, the World Health Organization (1994) promoted the use of the pathogram as an informative and data capturing tool that could help reduce intrapartum mishaps. The usage of the partogram within the intrapartum environment also introduced a dilemma as birth attendants spent quite a good amount of time using their eyes and hands (in pen and paper) capturing medical data onto the partogram instead of investing these resources onto the expectant mother and or fetus. This study adopted Design Science Research as a suitable research approach, strengthened by a pragmatic philosophical standpoint. This study involved the following methods; • A review of literature in the intrapartum environment, along with topics from relevant reference disciplines including speech recognition • A series of semi-structured contextual interviews with birth attendants, student nurses and senior midwives • A design science research study using the knowledge from the reference disciplines to design a hands-free voice driven epartogram • A simulation of the capturing of intrapartum data to evaluate and refine the prototype (epartogram) by applying anonymized intrapartum data driven by natural speech • An evaluation of the artifact (epartogram) based on a number of published guidelines recommended by scholars to demonstrate its potential utility as well as to establish if the solution is generic to the contextual environment. Although the introduction of ICT into the problem domain abetted the process of data capturing (specifically the referral process), the fundamental aspect of using the prototype to free the hands and eyes of the birth attendants proved challenging due to issues with the recognition of natural speech by speech recognition systems and background noise. Monitoring of MOU and the referral process from a lower MOU to a higher one could benefit a great deal from this study as the prototype thrived well in that regard. Natural speech recognition by machines in an uncontrolled environment is still at its infancy (some of the most powerful engines can not differentiate between background noise and direct instruction). Not withsatnding the challenges posed by the infancy of speech recognition, the artifact showed potential as a manual epartogram providing spatial access to multiple participating MOU via the cloud.

Повний текст джерелаThe research was conducted as part of a socio-tech initiative undertaken at the Cape Peninsula University of Technology. The socio-tech initiative overall focus was on addressing issues faced by rural and under-resourced communities in South Africa, specifically looking at Home-Based Healthcare (HBHC) primarily in the Western Cape. As research into the HBHC context in rural and under-resourced communities continued numerous issues around data and data-elements came to light. These data issues were especially prevalent in relation to the various paper forms being used by the HBHC initiatives that attempt to deliver care in these communities. The communities have the tendency to suffer from poor access to formal healthcare services and healthcare facilities. The data issues were primarily in terms of how data was defines and used within the HBHC initiatives. Within the HBHC initiatives that cater for rural and under-resourced communities there was a clear prevalence of paper-based systems, and a very low penetration of IT-based solution. Because similar and related data-elements are used throughout the paper forms and within different context these data-elements are inconsistently used and presented. The paper forms further obfuscate these inconsistencies as the paper forms regularly change due to internal and external factors. When these paper forms are changed date elements are added or removed without the changes to the underlying ontologies being considered.

Повний текст джерелаENGLISH ABSTRACT: This thesis investigates the complexities involved in Health Information Systems. The focus is on the factors of a) efficiency and b) usability. A case study is made of a recently implemented system in Charlotte Maxeke Johannesburg Academic hospital. The first objective of the research was to gain a deeper understanding of the complexities of Health Information Systems, and secondly to evaluate the situation at Charlotte Maxeke Johannesburg Academic Hospital. In Chapter 1 a detailed introduction of the thesis is offered. This includes, explaining what triggered the research, the objective of the research and the methodology used to conduct the research. In Chapter 2 the focus is on a literature review of Health Information Systems, system fundamentals and planning and implementation. It is clear that without a methodology, systems development becomes haphazard and subsequently a risky and expensive undertaking. While change is pervasive, introducing operational efficiencies sometimes may necessitate reviewing of information systems and business strategy, knowledge management and process orientation. In Chapter 3 the issue of usability is investigated. Several healthcare institutions have implemented information systems but evaluations of the usability of these systems are still under debate. For purposes of this research an evaluation method for system usability and survey questionnaires were developed. In Chapter 4 the case study of Charlotte Maxeke Johannesburg Academic Hospital is reported. The chapter also describes the data collection design, research limitations and delimitations, survey findings and interpretations. In Chapter 5 the implications and applications of Health Information Systems are discussed. After analysis of the survey results, it appears that the impact and benefits of the new Health Information System are only positive or realized in the patient administration division. The rest of the health professionals continue to manually capture clinical notes and other management information on pieces of papers, spread sheets and word documents. The thesis comes to the conclusion that despite widespread use of technology in other sectors, clinicians in hospitals do not use implemented automated systems. Implementation of systems is complex and problems associated with usability are not resolved and that traditional systems implementation methodologies may not apply.
AFRIKAANSE OPSOMMING: Die tesis ondersoek die faktore wat Gesondheidstelsels (HIC) ingewikkeld maak. Die fokus is op a) doeltreffendheid, en b) bruikbaarheid (uit gebruikersoogpunt). ‘n Gevallestudie word gemaak van ‘n stelsel wat onlangs by Chalotte Maxeke Johannesburg Akakdemiese Hospitaal in gebruik geneem is. Die eerste doelwit van die ondersoek was om die ingewikkeldheidsgraad van sodanige stelsels te probeer bepaal, en tweedens om die situasie in die hospitaal self te evalueer. In hoofstauk 1 word die agtergond en aanleiding tot die ondersoek uiteengesite, woel as die metodologiese keuses wat gemaak is. Hoofstuk 2 bied ‘n oorsig oor relevante literatuur ten ospigte van HIC. Dit is duidelik stlselontwikkeling riskant, onnodig duur en koersloos is as dit sonder ‘n duidelike metodologie geïmplementeer word. Verandering vind voortdurend plaas en die implementering van oprasionele doeltreffendheid mag vernadering in besigheidstrategie, informasiestelsels, kennisbestuur en processoriëntasie noodsaaklik maak. In hoofstuk 3 word bruikbaarheid ondersoek. Verskeie mediese instellings het soortgelyke stelsels in gebruik geneem, maar die bruikbaarheid daarvan is steeds onseker. Vir die doeleindes van hierdie tesis is ‘n eie evaluasiemetode ontwikkel en ‘n vraelys op grond daarvan opgestel. Hoofstuk 4 rapporteer die gevallestudie in Charlotte Maxeke Johannesburg Akademiese Horspitaal hospital. Datakolleksie, navorsingsafbakening en – beperkinge, sowel as vraelysresultate word aangebied. Hoofstuk 5 bespreek die implikasies en toepassings van HIC. Dit blyk dat die voordele van die stelsel slegs deur die pasiëntadministrasieafdeling geniet word. Alle ander afdeling gaan steeds voort met papiergebaseerde inligtingstelsels, aangevaul deur ad hoc gebruik van Excel en woordprossering. Die tesis kom tot die gevolgtrekking dat kliniese personeel avers is teen die gebruik van geoutomatiseerde informasiestelsels.

Повний текст джерелаAccess to healthcare is regarded as a basic and essential human right. It is widely known that ICT solutions have potential to improve access to healthcare, reduce healthcare cost, reduce medical errors, and bridge the digital divide between rural and urban healthcare centres. The access to personal healthcare records is, however, an astounding challenge for both patients and healthcare professionals alike, particularly within resource-restricted environments (such as rural communities). Most rural healthcare institutions have limited or non-existent access to electronic patient healthcare records. This study explored the accessibility of personal healthcare records by patients and healthcare professionals within a rural community hospital in the Eastern Cape Province of South Africa. The case study was conducted at the St. Barnabas Hospital with the support and permission from the Faculty of Informatics and Design, Cape Peninsula University of Technology and the Eastern Cape Department of Health. Semi-structured interviews, observations, and interactive co-design sessions and focus groups served as the main data collection methods used to determine the accessibility of personal healthcare records by the relevant stakeholders. The data was qualitatively interpreted using thematic analysis. The study highlighted the various challenges experienced by healthcare professionals and patients, including time-consuming manual processes, lack of infrastructure, illegible hand-written records, missing records and illiteracy. A number of recommendations for improved access to personal healthcare records are discussed. The significance of the study articulates the imperative need for seamless and secure access to personal healthcare records, not only within rural areas but within all communities.

Повний текст джерелаThis 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.

Повний текст джерелаHealthcare services are vital to all human beings, as our daily lives depend on them. In South Africa approximately eighty per cent of the population uses the public healthcare services. In the current healthcare systems data corruption exists which threatens data quality in the systems. The aim of this study was to understand the existing information handling processes and factors that affect the accuracy and integrity of healthcare data. A qualitative research methodology, under the interpretive paradigm was used for this investigation. Activity theory is used to formulate an analytical framework, the “healthcare information system data quality activity theory framework”. This was very helpful for understanding the healthcare information handling process as an activity system that consists of actors with individual goals. Though the goals are varied, they are joined together by the common objective. The logic of the framework is that a realisation of goals in the activity system depends on a number of factors. At the beginning, there must be a synchronous inter-linkage between the goals of the actors, the mediating factors such as adequate tools, user skills, enabling policies, and the systematic procedures that are diligently enforced. It is assumed that any situation which prevents this inter-linkage will have a negative impact on the realisation of the sought objective. The framework therefore, was very helpful in informing questions, the data collection and ultimately, the analysis processes. The public healthcare sector is the main source of data; other sources were literature, the Internet and books. The analysis of data was done using content analysis to find what themes emerge and the relationship (s) between them in what is being analysed. The findings reveal a lack of adherence to information handling procedures and processes which lead to corrupt data in the systems. In addition, most users have limited skills, which is a hindrance to them in performing their duties as expected by the healthcare sector. In fact, the healthcare sector is also challenged by systems which are constantly slow or down, due to limited network capacity and human errors. The presence of these challenges suggests non-adherence to data handling procedures, which explains the existing corrupt data in the healthcare systems. Therefore the recommendation is that the public healthcare administration must enhance their training programs. The training must be re-designed to cater for the needs of all users, regardless of their background. It needs to improve user skills and boast their confidence in using electronic systems. Obviously, any changes and improvements need to be sustainable, and the sector is unlikely to succeed without enforcement of new procedures. Therefore, adherence to data handling procedures must be strictly enforced, with policies thoroughly communicated to the users. That way, the sector will not only have systems and related policies, but also ensure their full exploitation for improved service delivery in the public healthcare sector in South Africa.

Повний текст джерелаHome-Based Healthcare (HBHC) is an important aspect of South Africa's healthcare system. HBHC is the provision of care services to patients by trained or semi-trained caregivers at home. In South Africa HBHC was introduced in 2001 to address many problems with traditional healthcare such as overcrowding in public health facilities. South Africa has one of the highest HIV/AIDS infection rates in the world, which is often accompanied by opportunistic infections such as tuberculosis. HBHC is envisaged to address these challenges, thus relieving the burden on primary healthcare. HBHC is itself faced with many problems which include poor information or data management, unclear information flows, and insufficient information storage. It is also not clear how caregivers use data elements and there is no coherent indigenous knowledge base for the capturing, implementation and utilisation of data elements in local HBHC providers. This is particularly important to caregivers who rely on frameworks of indigenous knowledge in interpreting and making decisions on how to provide a care service to patients. In reality, caregivers operate in indigenous environments requiring the utilisation of local knowledge. This study explores the relationships between, and approaches to, data elements in different HBHC providers and communities. Three interpretive case studies in the Eastern and Western Cape Provinces of South Africa were conducted. Semistructured interviews, focus groups, participant observation and document analysis were used for data collection. The primary research question was: What happens when caregivers from various communities interact with data elements when providing a care service? Caregivers' indigenous knowledge and use of data elements was then harnessed in a knowledge base. The results from this study can be used by HBHC managers to develop their forms and training materials as the initial set of data elements used in HBHC has been identified. Caregivers from different communities can also learn how these data elements are used in other communities.

Повний текст джерелаWaiting queues in pediatric emergency unit are a constant problem in many hospitals in Brazil. The introduction of new technologies can contribute to the management of the queues. However, research about mobile applications to that address this problem was not identified. The present study developed two main activities that are related but independent. The first was the development of a cross-platform mobile application aimed at reducing the waiting queue in the pediatric emergency room of a major hospital in Curitiba. Using a pre-booking/check-in model, the application indicates time slots when the flux of patients is low in the emergency room. The model sought to achieve a balance between demand of treatment and hosting capacity that would help manage overcrowding and maintain the responsiveness in the service. The mobile application has three main features: to show the number of children that are waiting for care, to present the estimated waiting time for an appointment and a check-in system for the queue. During the 90-day evaluation of the prototype, 2,835 downloads and installations on mobile devices were carried out with 35,811 registered accesses. The second activity was the analysis of the effects of the check-in system use in the pediatric emergency department queue. The application proposes a time slot with fewer patients in the queue for the user, minimizing the risk of adverse events. 129 complete observations of patients who used the check-in function were obtained. The data related to three types of patients’ waiting times in queue were analyzed: the real waiting time in the room considering the check time in the application, the waiting time considering the scheduled time generated by the application, and the waiting time considering the actual arrival time at the hospital. To analyze the results, the three types of waiting times were compared using the statistical method of analysis time. In the 129 observations of patients who used the check-in, the analysis showed that on average, patients waited for care 19.24 minutes compared to the average time 127.8 minutes of waiting in the queue for patients who do not used the application. The proposed method of check-in reduced the waiting time for parents who used the application in comparison to other parents, indicating that it could be used to contribute to the management of the overcrowding in pediatric emergency unit.

Повний текст джерелаThe present study was undertaken in a bid to meet an urgent need uncovered in medical-information systems (MIS) for a formal process whereby risks posing a threat to patients in medical institutions could be identified and controlled by means of the appropriate security measures. At the time of the study, however, no such formal risk-analysis model had yet been developed specifically for application in MIS. This gave rise to the development of RAMMO, a riskanalysis model specifically aimed at the identification of risks threatening the patient in his or her capacity as an asset in a medical institution. The author, therefore, managed to achieve her object with the study, namely to initiate a riskanalysis model that could be applied to medical environments. Following, an overview of the research method used in order to achieve the objectives of the study: Firstly, background information regarding the issues and problems to be addressed was obtained, and they provided the well-founded motivation for the study. Secondly, the development and importance of MIS in medical environments came under consideration, as well as the applicability of information security in an MIS. In the third instance, general terms and concepts used in the risk-management process were defined, by means of which definitions existing risk-analysis models were investigated and critically evaluated in a bid to identify a model that could be applied to a medical environment. Fourthly, a conceptual or draft design was suggested for a risk-analysis model developed specifically for medical environments. In doing so, the first two stages of the model, namely risk identification and risk assessment, were given special emphasis. The said model was then illustrated by means of a practical application in a general hospital in South Africa. The study culminated in a summation of the results of and the conclusions reached on the strength of the research. Further problem areas were also touched upon, which could become the focus of future research projects.

Повний текст джерелаThe practice of medicine changes constantly and rapidly. Consequently, it is difficult for clinicians to learn about innovations, given the vast quantity of information available. Evidence-based medicine (EBM) is the process by which practitioners turn clinical problems into questions, and then systematically integrate personal clinical expertise with the best available external evidence as the basis for clinical decisions. To practice EBM, the practitioner is required to search the literature for relevant material, and then to synthesise knowledge and apply findings to each patient. Clinicians require fast and specific access to multiple data sources, but the availability of electronic full text documents has substantially exacerbated the lack of time to read the clinical literature owing to the demands of clinical practice, and is further compounded by the fact that the Web contains much health-related misinformation. Clinicians therefore require a means of searching the literature that will enhance the retrieval of accurate and evaluated clinical data from ranked resources, whereby the most relevant information is retrieved first from the most likely source. Strong correlations exist between four primary steps in EBM, and the formula commonly used in search strategy design in the field of information seeking. The similarities inherent in these steps suggest that an evidence-based approach to information seeking might enable endusers in the health professions to enhance their searching skills and to translate the clinical question into an appropriate information-seeking strategy. A main problem and two sub-problems were investigated, namely whether: · a Web-based EBM information-seeking model could be designed to enhance the information-seeking skills of healthcare practitioners · it was possible to design an information-seeking model more closely aligned with the clinical decision-making model familiar to healthcare practitioners · it was possible to design such a model in a manner that could further enhance the translation of the clinical question into an appropriate information-seeking strategy. Various models in medicine and the domain of information seeking were investigated. It was found that the model of the clinical decision-making process accorded with all six phases of the information-seeking process (ISP), whereas other information-seeking models only addressed the ISP from the formulation of the problem onwards, thus ignoring prior stages of initiation, selection and exploration in the ISP. A Web-based EBM information-seeking model (Model C) was devised and tested for compatibility against a general Web-based information-seeking model, and was found to be valid. Model C was further empirically assessed against a Web site design methodology, and was again found to be compatible. A unique approach to EBM information seeking is thus offered by Model C, which incorporates all aspects of the clinical-decision-making metaphor, as well as the “PICO” EBM filters (Patient/Problem, Intervention, Comparative Intervention and Outcome), into a facet analysis template for the design of a clinical search strategy. Prior to selection of the EBM information resource, Model C further allows for the ranking of each resource and for the design of individual browsing and/or analytical search strategies, as appropriate, so as to enhance EBM information seeking amongst healthcare practitioners.

Повний текст джерелаLiterature pertaining to geriatric care contains rich information regarding the best practices related to geriatric health care issues. The publication domain of geriatric care is small as compared to other health related areas, however, there are over a million articles pertaining to different cases and case interventions capturing best practice outcomes. If the data found in these articles could be harvested and processed effectively, such knowledge could then be translated from research to practice in a quicker and more efficient manner. Geriatric literature contains multiple domains or practice areas and within these domains is a wealth of information such as interventions, information on care for elderly, case studies, and real life scenarios. These articles are comprised of a variety of causal relationships such as the relationship between interventions and disorders. The goal of this study is to identify these causal relations from published abstracts. Natural language processing and statistical methods were adopted to identify and extract these causal relations. Using the developed methods, causal relations were extracted with precision of 79.54%, recall of 81% while only having a false positive rate 8%.

Повний текст джерелаA study design has been developed that employs a dual modeling approach to identify factors associated with facility-level cancer screening improvement and how this is mediated by the use of clinical decision support. This dual modeling approach combines principles of (1) Health Informatics, (2) Cancer Prevention and Control, (3) Health Services Research, and (4) Organizational Change/Theory. The study design builds upon the constructs of a conceptual framework developed by Jane Zapka, namely, (1) organizational and/or practice settings, (2) provider characteristics, and (3) patient population characteristics. These constructs have been operationalized as measures in a 2005 HRSA/NCI Health Disparities Cancer Collaborative inventory of 44 community health centers. The first, statistical models will use: sequential, multivariable regression models to test for the organizational determinants that may account for the presence and intensity-of-use of clinical decision support (CDS) and information systems (IS) within community health centers for use in colorectal, breast, and cervical cancer screening. A subsequent test will assess the impact of CDS/IS on provider reported cancer screening improvement rates. The second, computational models will use a multi-agent model of network evolution called CONSTRUCT® to identify the agents, tasks, knowledge, groups, and beliefs associated with cancer screening practices and CDS/IS use to inform both CDS/IS implementation and cancer screening intervention strategies. This virtual experiment will facilitate hypothesis-generation through computer simulation exercises. The outcome of this research will be to identify barriers and facilitators to improving community health center facility-level cancer screening performance using CDS/IS as an agent of change. Stakeholders for this work include both national and local community health center IT leadership, as well as clinical managers deploying IT strategies to improve cancer screening among vulnerable patient populations.

Повний текст джерелаHealth Information Technology (HIT) has become an integral component of healthcare today. The HITECH Act (2009) and Meaningful Use objectives stand to bring wide-sweeping adoption and implementations of HIT in small, medium and large sized healthcare organizations across the country. Though recent literature has provided evidence for the benefits of HIT in the profession, there have also been a growing number of reports exploring the adverse effects of HIT. There has not, however, yet been a systematic account of the adverse effects of HIT in the healthcare system. The current push for HIT coupled with a lack of critical appraisal of the potential risks of implementation and deployment within the medical literature has led to a general unquestioning and unregulated acceptance of the implementation of technology in medicine and healthcare as a positive addition with little or no risk. While the benefits of HIT are clear, a review of the existing studies in the literature would provide a holistic vision of the adverse effects of HIT as well as the types and impact within the nation’s health care system to inform future HIT development and implementation. The development of a general understanding of these adverse effects can serve as a review and summary for the use of informatics professionals and clinicians implementing HIT as well as providing future direction for the industry in HIT implementations. Additionally, this study has value for moving forward in informatics to develop frameworks for implementation and guidelines and standards for development and regulation of HIT at a federal level. This study involves the use of an integrative literature review to identify and classify the adverse effects of HIT as reported in the literature. The purpose of this study is to perform an integrative review of the literature to 1) identify and classify the adverse effects of HIT; 2) determine the impact and prevalence of these effects; 3) identify the recommended actions and best practices to address the negative effects of HIT. This study analyzed 18 articles for HIT-induced error and adverse consequences. In the process, 228 errors and/or adverse consequences were identified, classified and represented in an operational taxonomic schema. The taxonomic representation consisted of 8 master categories and 30 subcategories. Additionally, the prevalence and impact of these errors were evaluated as well as recommendations and best practices in future systems design. This study builds on previous work in the medical literature pertaining to HIT-induced errors and adverse consequences and offers a unique perspective in analyzing existing studies in the literature using the integrative review model of research. It is the first work in combining studies across healthcare technologies and analyzing the adverse consequences across 18 studies to form a cohesive classification of these events in healthcare technology.

Повний текст джерелаIn 2009, Indianapolis Emergency Medical Service (I-EMS, formerly Wishard Ambulance Service) launched an electronic medical record system within their ambulances and started to exchange patient data with the Indiana Network for Patient Care (INPC). This unique system allows EMS personnel in an ambulance to get important medical information prior to the patient’s arrival to the accepting hospital from incident scene. In this retrospective cohort study, we found EMS personnel made 3,021 patient data requests (14%) of 21,215 EMS transports during a one-year period, with a “success” match rate of 46%, and a match “failure” rate of 17%. The three major factors for causing match “failure” were (1) ZIP code 55%, (2) Patient Name 22%, and (3) Birth Date 12%. This study shows that the ZIP code is not a robust identifier in the patient identification process and Non-ZIP code identifiers may be a better choice due to inaccuracies and changes of the ZIP code in a patient’s record.

Повний текст джерелаReducing medical error remains in the forefront of healthcare reform. The use of health information technology, specifically the electronic health record (EHR) is one attempt to improve patient safety. The implementation of the EHR in the Emergency Department changes physician workflow, which can have negative, unintended consequences for patient safety. Inaccuracies in clinical documentation can contribute, for example, to medical error during transitions of care. In this quasi-experimental comparison study, we sought to determine whether there is a difference in document quality, error rate, error type, cognitive load and time when Emergency Medicine (EM) residents use paper charts versus the EHR to complete physician documentation of clinical encounters. Simulated patient encounters provided a unique and innovative environment to evaluate EM physician documentation. Analysis focused on examining documentation quality and real-time observation of the simulated encounter. Results demonstrate no change in document quality, no change in cognitive load, and no change in error rate between electronic and paper charts. There was a 46% increase in the time required to complete the charting task when using the EHR. Physician workflow changes from partial documentation during the patient encounter with paper charts to complete documentation after the encounter with electronic charts. Documentation quality overall was poor with an average of 36% of required elements missing which did not improve during residency training. The extra time required for the charting task using the EHR potentially increases patient waiting times as well as clinician dissatisfaction and burnout, yet it has little impact on the quality of physician documentation. Better strategies and support for documentation are needed as providers adopt and use EHR systems to change the practice of medicine.
