Karlsson, Johan. "Information structures and workflows in health care informatics." Doctoral thesis, Umeå universitet, Institutionen för datavetenskap, 2010. http://urn.kb.se/resolve?urn=urn:nbn:se:umu:diva-33829.
Full textAbstract:
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.

Full textAbstract:
Healthcare organizations now consider increased efficiency, reduced costs, improved patient care and quality of services, and safety when they are planning to implement new information and communication technology (ICT) based applications. However, in spite of enormous investment in health information systems (HIS), no convincing evidence of the overall benefits of HISs yet exists. The publishing of studies that capture the effects of the implementation and use of ICT-based applications in healthcare may contribute to the emergence of an evidence-based health informatics which can be used as a platform for decisions made by policy makers, executives, and clinicians. Health informatics needs further studies identifying the factors affecting successful HIS implementation and capturing the effects of HIS implementation. The purpose of the work presented in this thesis is to increase the available knowledge about the impact of the implementation and use of HISs in healthcare organizations. All the studies included in this thesis used qualitative research methods. A case study design and literature review were performed to collect data.
This thesis’s results highlight an increasing need to share knowledge, find methods to evaluate the impact of investments, and formulate indicators for success. It makes suggestions for developing or extending evaluation methods that can be applied to this area with a multi-actor perspective in order to understand the effects, consequences, and prerequisites that have to be achieved for the successful implementation and use of IT in healthcare. The results also propose that HIS, particularly integrated computer-based patient records (ICPR), be introduced to fulfill a high number of organizational, individualbased, and socio-technical goals at different levels. It is therefore necessary to link the goals that HIS systems are to fulfill in relation to short-term, middle-term, and long-term strategic goals. Another suggestion is that implementers and vendors should direct more attention to what has been published in the area to avoid future failures.
This thesis’s findings outline an updated structure for implementation planning. When implementing HISs in hospital and primary-care environments, this thesis suggests that such strategic actions as management involvement and resource allocation, such tactical action as integrating HIS with healthcare workflow, and such operational actions as user involvement, establishing compatibility between software and hardware, and education and training should be taken into consideration.

Full textAbstract:
In the light of an ageing society with shrinking economic resources, deinstitutionalization of elderly care is a general trend. As a result, homecare is increasing, and increasingly shared between different health and social care organizations. To provide a holistic overview about the patient care process, i.e. to be patient-centred, shared homecare needs to be integrated. This requires improved support for information sharing and cooperation between different actors, such as care professionals, patients and their relatives. The research objectives of this thesis are therefore to study information and communication needs for patient-centered shared homecare, to explore how integrated information and communication technology (ICT) can support information sharing, and to analyze how current standards for continuity of care and semantic interoperability meet requirements of patient-centered shared homecare. An action research approach, characterized by an iterative cycle, an emphasis on change and close collaboration with practitioners, patients and their relatives, was used. Studying one specific homecare setting closely, intersection points between involved actors and specific needs for information sharing were identified and described as shared information objects. An integration architecture making shared information objects available through integration of existing systems was designed and implemented. Mobile virtual health record (VHR) applications thereby enable a seamless flow of information between involved actors. These applications were tested and validated in the OLD@HOME-project. Moreover, the underlying information model for a shared care plan was mapped against current standards. Some important discrepancies were identified between these results and current standards for continuity of care, stressing the importance of evaluating standardized models against requirements of evolving healthcare contexts. In conclusion, this thesis gives important insights into the needs and requirements of shared homecare, enabling a shift towards patient-centered homecare through mobile access to aggregated information from current feeder systems and documentation at the point of need.

Full textAbstract:
There is a marked trend of using information technologies to improve healthcare. Among all the health IT, electronic health record (EHR) systems hold great promises as they modernize the paradigm and practice of care provision. However, empirical studies in the literature found mixed evidence on whether EHRs improve quality of care. I posit two explanations for the mixed evidence. First, most prior studies failed to account for system use and only focused on EHR purchase or adoption. Second, most existing EHR systems provide inadequate clinical decision support and hence, fail to reveal the full potential of digital health. In this dissertation I address two broad research questions: a) Does meaningful use of EHRs improve quality of care? and b) How do we advance clinical decision making through innovative computational techniques of healthcare analytics? To these ends, the dissertation comprises four essays. The first essay examines whether meaningful use of EHRs improve quality of care through a natural experiment. I found that meaningful use significantly improve quality of care, and this effect is greater in historically disadvantaged hospitals such as small, non-teaching, or rural hospitals. These empirical findings present salient practical and policy implications about the role of health IT. On the other hand, in the other three essays I work with real-world EHR data sets and propose healthcare analytics frameworks and methods to better utilize clinical text (Essay II), integrate clinical guidelines and EHR data for risk prediction (Essay III), and develop a principled approach for multifaceted risk profiling (Essay IV). Models, frameworks, and design principles proposed in these essays advance not only health IT research, but also more broadly contribute to business analytics, design science, and predictive modeling research.

Full textAbstract:
Consumers face several challenges using the Internet to fill health-related needs. (1) In many cases, they face a language gap as they look for information that is written in unfamiliar technical language. (2) Medical information in social media is of variable quality and may be appealing even when it is dangerous. (3) Discussion groups provide valuable social support for necessary lifestyle changes, but are variable in their levels of activity. (4) Finding less popular groups is tedious. We present solutions to these challenges.
We use a novel adaptation of topic models to address the language gap. Conventional topic models discover a set of unrelated topics that together explain the combinations of words in a collection of documents. We add additional structure that provides relationships between topics corresponding to relationships between consumer and technical medical topics. This allows us to support search for technical information using informal consumer medical questions.
We also analyze social media related to eating disorders. A third of these videos promote eating disorders and consumers are twice as engaged by these dangerous videos. We study the interactions of two communities in a photo-sharing site. There, a community that encourages recovery from eating disorders interacts with the pro-eating disorder community in an attempt to persuade them, but we found that this attempt entrenches the pro-eating disorder community more firmly in its position.
We study the process by which consumers participate in discussion groups in an online diabetes community. We develop novel event history analysis techniques to identify the characteristics of groups in a diabetes community that are correlated with consumer activity. This analysis reveals that uniformly advertise the popular groups to all consumers impairs the diversity of the groups and limits their value to the community.
To help consumers find interesting discussion groups, we develop a system for personalized recommendation for social connections. We extend matrix factorization techniques that are effective for product recommendation so that they become suitable for implicit power-law-distributed social ratings. We identify the best approaches for recommendation of a variety of social connections involving consumers, discussion groups and discussions.

Full textAbstract:
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.

Full textAbstract:
Background Health information systems have emerged as a major component in our response to the trends of rising demands in health care. The insight being gained from the evaluation of those systems can critically influence the shaping of the response. Summative or formative evaluation of health information systems assesses their quality, acceptance, and usefulness, creates insight for improvement, discriminates between options, and refines future development strategies. But the evaluation of health information systems can be challenging due to the propagation of their impacts through multiple socio-technological layers till the ultimate recipients, their heterogeneity and fast evolvement, and the complexity of health care settings and systems. Aim This thesis tries to explain the challenges of evaluation of health information systems with a narrow down on determining evaluation aspects and to propose relevant solutions. The thesis goes for solutions that mitigate heterogeneity and incomparability, recruit or extend available evaluation models, embrace a wide context of application, and promote automation. Method The literature on health information systems evaluation, methods of dealing with heterogeneity in other disciplines of information systems, and ontology engineering were surveyed. Based on the literature survey, the UVON method, based on ontology engineering, was first developed in study 1. The method was applied in FI-STAR, a European Union project in e-Health with 7 use-cases, for summative evaluation of the individual and whole e-health applications. Study 2, extended the UVON method for a formative evaluation during the design phase. Results Application of the UVON method resulted in evaluation aspects that were delivered to the seven use-cases of the FI-STAR project in the form of questionnaires. The resulted evaluation aspects were considered sensible and with a confirming overlap with another highly used method in this field (MAST). No significant negative feedback from the FI-STAR use-case owners (n=7) or the respondents (n=87 patients and n=30 health professionals) was received or observed. Conclusion In the evaluation of health information systems --possibly also in other similarly characterized systems-- ontology engineering methods, such as the proposed UVON method, can be applied to create a flexible degree of unification across a heterogeneous set of evaluation aspects, import evaluation aspects from other evaluation methods, and prioritize between quality aspects in design phase. Ontologies, through their semantic network structures, can capture the extracted knowledge required for evaluation, facilitate computation of that knowledge, promote automation of evaluation, and accommodate further extensions of the related evaluation methods by adding new features to their network structure.

Full textAbstract:
Notwithstanding the obvious potential advantages of information and communications technology (ICT) in the enhanced provision of healthcare services, there are some concerns associated with integration of and access to electronic health records. A security violation in health records, such as an unauthorised disclosure or unauthorised alteration of an individual's health information, can significantly undermine both healthcare providers' and consumers' confidence and trust in e-health systems. A crisis in confidence in any national level e-health system could seriously degrade the realisation of the system's potential benefits. In response to the privacy and security requirements for the protection of health information, this research project investigated national and international e-health development activities to identify the necessary requirements for the creation of a trusted health information system architecture consistent with legislative and regulatory requirements and relevant health informatics standards. The research examined the appropriateness and sustainability of the current approaches for the protection of health information. It then proposed an architecture to facilitate the viable and sustainable enforcement of privacy and security in health information systems under the project title "Open and Trusted Health Information Systems (OTHIS)". OTHIS addresses necessary security controls to protect sensitive health information when such data is at rest, during processing and in transit with three separate and achievable security function-based concepts and modules: a) Health Informatics Application Security (HIAS); b) Health Informatics Access Control (HIAC); and c) Health Informatics Network Security (HINS). The outcome of this research is a roadmap for a viable and sustainable architecture for providing robust protection and security of health information including elucidations of three achievable security control subsystem requirements within the proposed architecture. The successful completion of two proof-of-concept prototypes demonstrated the comprehensibility, feasibility and practicality of the HIAC and HIAS models for the development and assessment of trusted health systems. Meanwhile, the OTHIS architecture has provided guidance for technical and security design appropriate to the development and implementation of trusted health information systems whilst simultaneously offering guidance for ongoing research projects. The socio-economic implications of this research can be summarised in the fact that this research embraces the need for low cost security strategies against economic realities by using open-source technologies for overall test implementation. This allows the proposed architecture to be publicly accessible, providing a platform for interoperability to meet real-world application security demands. On the whole, the OTHIS architecture sets a high level of security standard for the establishment and maintenance of both current and future health information systems. This thereby increases healthcare providers‘ and consumers‘ trust in the adoption of electronic health records to realise the associated benefits.

Full textAbstract:
When the Swedish National IT Strategy for Health and Social Care was introduced in 2006, intensive work started in implementing Information Systems (IS) in Swedish healthcare organizations. To follow up on the requests for more research with a combined socio-technical focus on challenges, the overall aim of this thesis was to identify social challenges when implementing IS in a Swedish healthcare organization. Furthermore, the aim was to understand the impact of identified social challenges when implementing IS in this context by putting them in an interdisciplinary Applied Health Technology theoretical framework. Institutional ethnography and phenomenological hermeneutics influenced the study design. Study 1 aimed to investigate different meanings of accessibility when implementing Health Information Technology in everyday work practice. The results indicate that accessibility depends on working routines, social structures and patient relationship. When an IT strategy and interaction in everyday work use the same word in different ways there will be consequences. Study 2 sets out to describe experience-based reflections on discharge planning as narrated by nursing staff in primary healthcare, along with their concerns about how the introduction of video conferencing might influence the discharge planning situation. It was found that there is a need for improvement in communication and understanding between nursing staff at the hospital and in primary healthcare. The aim of study 3 was to explore social challenges when implementing IS in everyday work in a nursing context. Power (changing the existing hierarchy, alienation), Professional identity (calling on hold, expert becomes novice, changed routines), and Encounter (ignorant introductions, preconceived notions) were categories presented in the findings. The aim of study 4 was to explore and obtain a deeper understanding of how identified social challenges have an influence on the implementation process of IS, based on healthcare staff’s experiences on micro, meso and macro levels of Swedish Healthcare organizations. It was found that the challenges were related to the steps of putting into practice, making IS a part of everyday work routine and establishing an identity in the implementation process. In the thesis’s discussion, social challenges when implementing IS in Swedish healthcare organizations and how they might be met and dealt with constructively are further reflected upon in relation to the interdisciplinary theoretical framework and as possible consequences of the modernity-era. This thesis contributes to the starting up of a discussion of how ingrained professional characteristics are important to feel secure of being part of an established profession. If the characteristics are questioned, the whole professional performance is threatened. One consequence of this insight is the reinforcement of the realization that a basic understanding of IS and IS implementation processes in healthcare organizations needs to be integrated in to the construction of professional identity of nurses already from the start in nursing education.

Thesis (MPhil)--Stellenbosch University, 2013.ENGLISH 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.

Full textAbstract:
Appropriate e-services as well as revenue generation capabilities are key to the deployment and the sustainability for ICT installations in poor areas, particularly common in developing country. The area of e-Health is a promising area for e-services that are both important to the population in those areas and potentially of direct interest to National Health Organizations, which already spend money for Health campaigns there. This thesis focuses on the design, implementation, and full functional testing of HealthAware, an application that allows health organization to set up targeted awareness campaigns for poor areas. Requirements for such application are very specific, starting from the fact that the preparation of the campaign and its execution/consumption happen in two different environments from a technological and social point of view. Part of the research work done for this thesis was to make the above requirements explicit and then use them in the design. This phase of the research was facilitated by the fact that the thesis' work was executed within the context of the Siyakhula Living Lab (SLL; www.siyakhulaLL.org), which has accumulated multi-year experience of ICT deployment in such areas. As a result of the found requirements, HealthAware comprises two components, which are web-based, Java applications that run in a peer-to-peer fashion. The first component, the Dashboard, is used to create, manage, and publish information for conducting awareness campaigns or surveys. The second component, HealthMessenger, facilitates users' access to the campaigns or surveys that were created using the Dashboard. The HealthMessenger was designed to be hosted on TeleWeaver while the Dashboard is hosted independently of TeleWeaver and simply communicates with the HealthMessenger through webservices. TeleWeaver is an application integration platform developed within the SLL to host software applications for poor areas. Using a core service of TeleWeaver, the profile service, where all the users' defining elements are contained, campaigns and surveys can be easily and effectively targeted, for example to match specific demographics or geographic locations. Revenue generation is attained via the logging of the interactions of the target users in the communities with the applications in TeleWeaver, from which billing data is generated according to the specific contractual agreements with the National Health Organization. From a general point of view, HealthAware contributes to the concrete realizations of a bidirectional access channel between Health Organizations and users in poor communities, which not only allows the communication of appropriate content in both directions, but get 'monetized' and in so doing becomes a revenue generator.

Full textAbstract:
In Saudi Arabia, medical errors are at an alarming level. Lack of a Health Information Exchange (HIE) system is one the greatest reasons for medical errors in the Kingdom. Health care in many countries has evolved with the invention of electronic health information exchange system, henceforth HIE. This research paper purposes to implement HIE in Saudi Arabia, which entirely does not have a system of the sort. It is imperative instill HIE in the health care system in Saudi to allow physicians, nurses, health care facilities as well as patients to electronically share medical information in a safe and secure manner.
Many countries such as United States, New Zealand and Germany have had great success with the HIE system and have reported vast benefits. Benefits of HIE are such as reduction of health care cost as well as decreasing medical errors. For Saudi Arabia to reach the same heights, many stakeholders will be involved in the triumph of the HIE system in the Kingdom of Saudi Arabia. The biggest contributor will be the Ministry of Health, which will be in charge of implementing as well as making the system mandatory in the main four hospitals in the country: Shomasy, Kind Saud University Hospital, Ministry of interior Hospital and Ministry of Defense Hospital. Each hospital having their own current medical information recording system, will now have one universal system that is made sure to be secure and safe for patients as well as other participating organizations who have access to the HIE system.
The main concentration of the HIE system in Saudi Arabia will be in the emergency care of these four hospitals. It is crucial to have an organized and controlled way of recording as well as accessing patient medical records electronically, in a fast and effective way. This paper proposes that an HIE system in Saudi Arabia will reduce the cost of medical care and decrease medical errors. Through the use of Lean thinking and the use of quality tools, the HIE system will be able to change and increase the reliably as well as effectiveness of Urgent Care in the country and therefore have consequent benefits as well. Also, understanding who is going to play a great role in the triumph of the HIE system, such as the Ministry of Health and knowing what stakeholders will need to be affiliated and contribute will lead the project to a better success.

However, errors still occur, and many times are preventable. Configurations of health information technology systems should match clinical workflows to promote usage as intended. The purpose of this quality improvement project was to evaluate the impact of revised system configurations and use of a blood product transfusion system for the administration of blood products after one year of implementation. The method of heuristic evaluation is a usability engineering method for finding problems in a user interface design with the input of a small workgroup of subject matter experts. The project site had experienced reported incidents of blood product administration error as well as problems with systems communication since the implementation of the blood transfusion system. There were 31 nurse clinical educator staff users of the system who completed a survey evaluation of their perceptions of the blood transfusion system before and after configuration changes. The findings revealed that the mean quality and productivity score after the system configuration occurred was significantly higher than the mean score prior to the system configuration change, t (30) = -7.93, p < .001. The correlation between the one survey was also statistically significant, r = .46, p = .009. This project supports positive social change by reducing the potential for error for system users in the process of the blood administration process through heuristic evaluation through the implementation of changes to the technological system.

Full textAbstract:
A major problem to be solved in health informatics is high quality, structured and timely data collection. Standard terminologies and uniform domain conceptual models are important steps to alleviate this problem which are also proposed to enable interoperability among systems. With the aim of contributing to the solution of this problem, this study proposes novel features for the Archetypes and multi-level
modeling technique in health information and knowledge modeling. The study consists of the development of a research prototype for endoscopic data management,
and based on that experience, the extension of Minimal Standard Terminology in Digestive Endoscopy (MST). A major contribution of the study consists of significant extensions to the modeling formalism. The proposed modeling approach may be used in the design and development of health information systems based on archetypes for structured data collection, validation and dynamic user interface creation. The thesis
work is aimed to make considerable contribution to the emerging Electronic Health Records (EHR) standards and specifications.

Full textAbstract:
This system is concerned with the design and implementation of a community health information system which fulfils some of the local needs of fourteen nursing and para-medical professions in a district health authority, whilst satisfying the statutory requirements of the NHS Korner steering group for those professions. A national survey of community health computer applications, documented in the form of an applications register, shows the need for such a system. A series of general requirements for an informations systems design methodology are identified, together with specific requirements for this problem situation. A number of existing methodologies are reviewed, but none of these were appropriate for this application. Some existing approaches, tools and techniques are used to define a more suitable methodology. It is unreasonable to rely on one single general methodology for all types of application development. There is a need for pragmatism, adaptation and flexibility. In this research, participation in the development stages by those who will eventually use the system was thought desirable. This was achieved by forming a representative design group. Results would seem to show a highly favourable response from users to this participation which contributed to the overall success of the system implemented. A prototype was developed for the chiropody and school nursing staff groups of Darlington health authority, and evaluations show that a significant number of the problems and objectives of those groups have been successfully addressed; the value of community health information has been increased; and information has been successfully fed back to staff and better utilised.

Full textAbstract:
The Patient Protection and Affordable Care Act (PPACA) is slowly transforming the U.S. Health Care System from a fee-for-service structure, which reimburses providers based on the quantity of patient encounters, to a new structure that emphasizes the value of care. Since value can be interpreted differently among various stakeholders, quality measures have been established by government and nonprofit sources. These quality measures serve as agreed-upon criteria by which to measure the achievement of value in health care. While these measures help to improve the quality of health care, they can also be burdensome to physicians and health care organizations. Implementation of quality measurement programs requires the involvement of highly intelligent people who think about what to measure, what to focus on, and how to accomplish outcomes. Thus, the process of selecting measures and compiling recommendations (reports) can be time consuming, complicated, and expensive.
Applying SELP coursework fundamentals, key process activities outlined by INCOSE, and the DoD Architectural Framework, a quality measure information system was developed. The primary business objective (top level requirement) of the project was to reduce the cost and improve the quality of the measure selection and report generation processes. First, fundamental systems engineering principles were applied to understand the problem, conduct a lean analysis, identify stakeholders' needs, and derive a set of requirements to meet the primary business objective. Subsequently, five alternative solutions were evaluated to identify a preferred solution that could best meet the primary business objective while minimizing risk. The DoD Architectural Framework and course material from Integration of Hybrid Hardware and Software Systems (SELP 560) was then applied to develop, represent, and understand the information system architecture. Finally, leveraging Management Information Systems Coursework (MBAA 609), a system prototype was created utilizing Microsoft Access.
The system prototype demonstrated a capability to reduce the cost and improve the quality of the health care quality measure selection and report generation processes. Utilizing pre-selected associations between various quality measures and categories of care, comprehensive quality measure reports can be generated in a matter of seconds for many categories of medical care. These comprehensive reports serve to educate users about various quality measures and to aid administrators in the development of comprehensive quality measurement programs. In one particular example, health care organizations will utilize the generated quality measure reports for the purpose of redesigning compensation and incentive pay for physicians and health care executives. In this particular example, estimates show that the system prototype is expected to reduce the labor associated with measure research and selection by approximately 49%, resulting in thousands of dollars of estimated savings. Additionally, the system will automate complicated measure search processes, which will increase the quality and consistency of the reported data.

Abstract
The main focus of this study is the identification of factors influencing the use and effectiveness of information
system development methodologies (Le., systems development methodologies) in health information
systems. In essence, it can be viewed as exploratory research, utilizing a conceptual research model to
investigate the relationships among the hypothesised factors. More specifically, classified as behavioural
science, it combines two theoretical models, namely the Unified Theory of Acceptance and Use of
Technology and the Expectancy Disconfirmation Theory. The main aim of behavioural science in information
systems is to assist practitioners (Le., social actors) in improving business processes and competitiveness,
thus the effective use of information systems. A wider view of behavioural science incorporates other social
actors (e.g., end users) and organisational actors (e.g., executives). In health information systems, the
effective use of information systems is especially relevant Health information systems are vital in the area of
health care, since only by having access to pertinent health information, can the correct decisions relating to
diagnostics and curative procedures be made. The use of systems development methodologies in health
information systems development is therefore crucial, since they can make the development process more
effective, while improving software quality.
By empirically evaluating the conceptual research model, utilizing a survey as the main research method and
structural equation modelling as the main statistical technique, meaningful results were obtained. Focussing
on the factors influencing the individual's behavioural intent, it was found that the compatibility of systems
development methodologies to the developer's pre-existing software development style is vital. Furthermore,
performance expectancy, self-efficacy, organisational culture, policies, customer influence, voluntariness and
facilitating conditions, all directly influenced the use of systems development methodologies, with policies and
customer influence playing a significant role, especially in relation to health information systems. No
significant direct effects or indirect effects could be established for the factors effort expectancy, personal
innovativeness and social influence. It appears that individuals working in the health care software
development discipline are more autonomous, less influenced by others. Also, the lack of support for the
factor effort expectancy may indicate that systems development methodologies have entered a mature state,
with less concern on the effort required for use. Furthermore, with regard to effectiveness and the continued
use of information systems methodologies, satisfaction had a significant direct effect, with confirmation
having a significant indirect effect.

Includes bibliographical references (p. 125-133).
Health information exchange (HIE) - the electronic exchange of health information among healthcare institutions - has been projected to hold enormous promise as an antidote to the fragmented healthcare delivery system in the United States. After decades of mostly failed attempts, we still do not know how to make HIE work. This thesis is the beginning of a systematic understanding of HIE, focusing on the clinical users and the context in which the users and the technology interact. It uses a systems approach to understand HIE from the perspectives of the core stakeholders including healthcare providers, patients, health IT vendor companies, public policy, and the HIE organizations that supply data exchange services. The core contributions of the thesis are contained in four studies. Values of healthcare providers as stakeholders in HIE In a stud y of three communities, healthcare provider organizations were found to expect regional HIE organizations to bring them benefits from the ability to measure care quality. However, one relatively larger community placed greater value on the strategic interests of its individual provider institutions, whereas two smaller communities valued the interests of the communities as a whole. Factors that affect clinicians' usage of HIE. In a study of clinician-users of an operational HIE, usage factors were categorized as motivators and moderators. Motivators for individual clinicians' usage of HIE included improving care quality and time savings. Moderators were numerous and included gaps in data, workflow complexity and usability issues. Several policy options and implications are discussed including: requiring HIE organizations to report metrics of HIE contributions and accesses; certifying HIE vendor companies to provide standardized usage metrics; and creating incentives for clinicians as well as HIE organizations and regional health IT extension centers to meet HIE usage targets. Analysis of opportunities to use HIE. In one community, 51% of visits involved "care transitions" among individual providers, and 36-41% involved care transitions between medical groups. The percentage of a provider's visits which involved care transitions varied considerably by clinical specialty and even within specialties. Within primary care, individual clinicians' "transition percentages" varied from 32% to 95%. This study discusses how policies designed to foster HIE usage should take this variation into account. Analysis of mergers and provider recruitment on HIE value. In a simulation study of patient visit patterns in 10 communities, the results suggest that even after substantial consolidation of medical groups, an HIE would still have considerable value as measured by the number of opportunities for data exchange. However, in each community a small number of medical groups were key: if absent from a community HIE, these groups would reduce the value by 50%. Conversely, if they were the only groups participating, the HIE's value would only achieve 10-20% of its value with all groups participating. The results of these studies suggest that HIE will be needed even in the event of the expected large-scale consolidation of healthcare providers. However, efforts will be needed to recruit medical groups to join HIE organizations, to improve HIE technology, and to train clinicians to integrate HIE into their workflows.

Thesis (MTech (Information Technology))--Cape Peninsula University of Technology, 2016.Access 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.

In the healthcare environment, various types of patient information are stored in electronic format. This prevents the re-entering of information that was captured previously. In the past this information was stored on paper and kept in large filing cabinets. However, with the technology advancements that have occurred over the years, the idea of storing patient information in electronic systems arose. This led to a number of electronic health information systems being created, which in turn led to an increase in possible security risks. Any organization that stores information of a sensitive nature must apply information security principles in order to ensure that the stored information is kept secure. At a basic level, this entails ensuring the confidentiality, integrity and availability of the information, which is not an easy feat in today’s distributed and networked environments. This paved the way for organized standardization activities in the areas of information security and information security management. Throughout history, there have been practices that were created to help “standardize” industries of all areas, to the extent that there are professional organizations whose main objective it is to create such standards to help connect industries all over the world. This applies equally to the healthcare environment, where standardization took off in the late eighties. Healthcare organizations must follow standardized security measures to ensure that patient information stored in health information systems is kept secure. However, the proliferation in standards makes it difficult to understand, adopt and deploy these standards in a coherent manner. This research, therefore, proposes a standards-based security model for health information systems to ensure that such standards are applied in a manner that contributes to securing the healthcare environment as a whole, rather than in a piecemeal fashion.

As a discipline Management Information System (MIS) is relatively new. Its short history has been characterised with epistemological dialectism. The current conflict and debate about MIS inquiry is broadly between the advocates of the social systems and technical systems perspectives. Few authors have made positive contributions toward clarifying the meaning and nature of MIS, and the appropriate design framework for MIS development. This thesis adds to their effort by using a MIS designed and implemented through action research at the North Western Regional Health Authority. There are seven Chapters in this thesis. Chapters One and Two examine the nature of the problem addressed by this research; the project history, ontological assumptions and research strategy. Chapter Three examines the debate, nature and conflicting views about MIS. It defines the theoretical problem addressed by this thesis and proposes a new concept of MIS. The theoretical problems are dealt with in Chapter Four. In Chapter Five the application of the theoretical concepts developed in Chapter Four is demonstrated in the design of MIS. Chapter Six relates some of the findings of this thesis to the work of other authors. It also examines the problem of human inquiry and the suitability of action research for MIS research. The main findings of this research summarised in Chapter Seven provide a new perspective of MIS as a purposeful system; the taxonomy of purposeful systems; primary context and secondary context of MIS; context analysis and context evaluation of MIS.

Full textAbstract:
The development outcome of ICT and information systems in developing countries is often influenced by international development policies and the action of international actors such as donor agencies. In particular, ICT adoptions and implementations in developing countries may be influenced by the contradictions arising mainly from the tension between international managerialist development policies and the main rationalities of actors in the local implementation context. Based on the case study of health information systems in Kenya, the objective of this thesis is to increase the understanding of how these contradictions may affect the development and change potential of health information systems and ICTs in developing countries in relation to international development policies. Drawing on a dialectical perspective on institutional work, the thesis argues that the change and development trajectories arising from the implementation and usage of health information systems depend on how actors involved in the restructuring of health information systems – i.e. donor partners, national decision makers and local health information systems managers and users – respond to the ongoing dialectic between global and local pressures of institutional change and stability. The main findings of the research presented in this thesis point to the importance of analysing political donor relations and the institutional entrepreneurship of local actors in order to understand the change and development outcomes of health information systems and ICT in developing countries.

Full textAbstract:
Since the early 20th century, the view has developed that high quality health care can be delivered only when all the pertinent data about the health of a patient is available to the clinician. Various types of health records have emerged to serve the needs of healthcare providers and more recently, patients or consumers. These health records include, but are not limited to, Personal Health Records, Electronic Heath Records, Electronic Medical Records and Payer-Based Health Records. Payer-Based Health Records emerged to serve the needs of medical aids or health care plans. Electronic Medical Records and Electronic Health Records were targeted at the healthcare provider market, whereas a gap developed in the patient market. Personal Health Records were developed to address the patient market, but adoption was slow at first. The success of online social networking reignited the flame that Personal Health Records needed and online consumer-based Personal Health Records were developed. Despite all the various types of health records, there still seems to be a lack of meaningful use of personal health records in modern society. The purpose of this dissertation is to propose a framework for Personal Health Records in online social networking, to address the issue of a lack of a central, accessible repository for health records. In order for a Personal Health Record to serve this need it has to be of meaningful use. The capability of a PHR to be of meaningful use is core to this research. In order to determine whether a Personal Health Record is of meaningful use, a tool is developed to evaluate Personal Health Records. This evaluation tool takes into account all the attributes that a Personal Health Record which is of meaningful use should comprise of. Suitable ratings are allocated to enable measuring of each attribute. A model is compiled to facilitate the selection of six Personal Health Records to be evaluated. One of these six Personal Health Records acts as a pilot site to test the evaluation tool in order to determine the tool’s utility and effect improvements. The other five Personal Health Records are then evaluated to measure their adherence to the attributes of meaningful use. These findings, together with a literature study on the various types of health records and the evaluation tool, inform the building blocks used to present the framework. It is hoped that the framework for Personal Health Records in online social networking proposed in this research, may be of benefit to provide clear guidance for the achievement of a central or integrated, accessible repository for health records through the meaningful use of Personal Health Records.

Full textAbstract:
The IT artifact is at the core of the information systems (IS) discipline and yet most IS research does not directly theorize the IT artifact or its nomological network (Benbasat and Zmud 2003; Orlikowski and Iacono 2001). This research seeks to answer a repeated call for more direct engagement with the IT artifact and its nomological net with affordance theory adopted as the basis for this theoretical work. An exploratory case study was conducted to answer the research question, how do the material properties of health information systems enable and constrain the work practices of clinicians? The study was conducted at a large urban acute care hospital in the Midwestern United States with registered nurses working on inpatient care units as the clinicians of interest. Through interviews with nurses and other clinical stakeholders and the observation of nurse’s work practices on three patient care units in the hospital, theoretical insights were developed on the nature of affordances for information systems research. IS affordances are defined in this study as relationships between abilities of an individual and features of an information systems within the context of the environment in which they function. The concepts of an affordance range and an affordance threshold are proposed as theoretical constructs in the nomological network of affordances that help to explain the use of information systems as a function of the difficulty of acting on IS affordances. The relationship between affordances and constraints is theorized and linked to the affordance range and threshold with the assertion that constraints are closely associated with the difficulties experienced by users in acting on IS affordances. The challenge of studying IS affordances in all their complexity is discussed with the suggestion that researchers take the user’s perspective of affordances to alleviate the need for repeated decomposition. Finally, the role of information systems in facilitating social interaction is emphasized through the concept of affordances for sociality. The contribution of this research to the IS field is a more nuanced understanding of the nature of the IT artifact and its relationship to the users of that technology.

Full textAbstract:
Currently, C Hospital lacks a standardized nursing informatics competency program to validate nurses' skills and knowledge in using electronic medical records (EMRs). At the study locale, the organization is about to embark on the implementation of a new, more comprehensive EMR system. All departments will be required to use the new EMR, unlike the current policy that allows some areas to still document on paper. The Institute of Medicine, National League of Nursing, and American Association of Colleges of Nursing support and recommend that information technology be an essential core competency for nurses. Evidence of the need for nursing informatic competencies was found through a literature search using CINHAL, Proquest Nursing, Medline, and Pubmed search lines. Concepts searched were competencies, nursing informatics, health information technology, electronic health record, information technology literacy, nursing education, information technology training, and curriculum. The Staggers Nursing Computer Experience Questionnaire was distributed to 300 nurses practicing within the hospital setting to obtain baseline data on current nursing computer knowledge and skill level. This validated tool was created by Nancy Staggers in 1994 and used in other process improvement efforts similar to this one. The assumption was that nursing competency levels with computers were varied through the hospital. The data obtained from the questionnaire, through Zoho Survey tool, confirmed this assumption and were used to help create the education, support, and competency plan for the future. Data was analyzed through the built-in reports and interactive charts that the Zoho survey tool provides. The new EMR and all the new processes that come with it will be the framework of nursing care. Having competent nurses in the use of the EMR will optimize the quality of patient care delivered.

The purpose of this study was to determine the factors associated with outsourcing of information systems (IS), and if there is a difference in IS sourcing based on the strategic value of the outsourced functions. The theoretical framework is based upon a synthesis of strategic management theory (SMT) and transaction cost economics (TCE) as they apply to vertical integration in the health care sector; therefore, IS sourcing behavior was conceptualized as a case of vertical integration. The conceptual model proposed that sourcing behavior would be determined by asset specificity, uncertainty, the interaction of asset specificity and uncertainty, bargaining power, corporate strategy needs, and the strategic value of the IS functions outsourced.A cross sectional design was used, consisting of data from the American Hospital Association (AHA), the Area Resource File (ARF), the HIMSS Analytics database, and the Centers for Medicare and Medicaid Services (CMS) hospital cost reports for 2003. The final sample consisted of 1,365 health care delivery systems and 3,452 hospitals. Analysis was conducted using a two-stage negative binomial regression model (using instrumental variables) to correct for suspected endogeneity. Tests of joint restrictions using the group of variables derived from TCE and SMT, respectively, were done with the dependent variable divided between strategic and non-strategic IS functions (the division was done based on a model of Core IS Capabilities developed as a model for a high-performance IS function).The results supported the relationship between bargaining power and IS outsourcing. Results for asset specificity and corporate strategy needs were significant in the opposite direction than hypothesized. No other findings were significant. These results suggest that hospital system managers are likely not considering significant factors when making sourcing decisions, including the relative strategic value of the functions they are outsourcing. This study contributes to the limited body of knowledge surrounding IS sourcing behavior in the health care sector. Future research should examine the effect of cost on IS sourcing decisions, and consider the use of alternative theoretical frameworks, particularly Institutional Theory.

Over the last two decades various information management processes have evolved in South Africa’s public health system. Most notably a self-service business intelligence tool has emerged at the national level which has been supported by the presence of a Routine Health Information System. Corporate business intelligence and its underlying process are well documented but not in the public health domain. The emergence of this tool and the underlying support processes are investigated in a longitudinal case study. Complex adaptive systems theory is used to demonstrate the evolutionary path of business intelligence processes according to four key areas, namely data quality, master data management, data warehousing and analytics. These processes have developed out of an information management culture that has been nurtured by a participatory approach which required an attractor: the improvement of health services through the collection and use of information. The evolution of these processes took place through a bottom up approach that relied on distributed control structures, self-organization and regular engagement within the CAS that is South Africa’s public health system. This created an environment in which information quality practices and master data management processes enabled the continued production of data for warehousing and analytics. Findings will show how business intelligence processes have evolved within a public health setting to the point that they are supported by a new policy that ensures data integrity, presence, quality and use processes. These processes have developed and stabilized over many iterations and have enabled the establishment of a country level self-service business intelligence platform for health managers.

In public safety, geography plays a significant role. One of the most important front-line elements of public safety is an efficient emergency transport and care system. The capacity to access and process information rapidly and organize resources where needed can be critically important in an emergency situation. Information about the locality of an event or a disaster is often vital in knowing how to respond. A significant operation in handling emergency situations is the routing of ambulances to incident sites and then to the closest appropriate hospitals. One of the important steps to survival in an emergency is quick response time.

(METU) Emergency Service, Ankara, Turkey. In the study, geographical information systems (GIS) technology is used in assisting the development and implementation of an emergency medical service (EMS) response system.
In this prototype, while choosing a proper facility, the available quantity of beds, respiratory equipments and doctors in a hospital's intensive care room and the best traffic routes to the hospital in hand are also considered. The ARSAP is expected to shorten the commuting time and hence to reduce the damage to the patient to the lowest level and allow the ambulance staff to perform their task better. The results generated using the ARSAP are validated and analyzed by comparing with currently practiced emergency call paths data collected with the help of METU Emergency Service ambulance drivers.

Full textAbstract:
Health care is increasingly being provided by collaborative teams that involve multiple health care providers at multiple locations. To date, most of that collaboration is on an ad-hoc basis via phone calls, faxes, and paper based documentation. However, Internet and wireless technologies provide an opportunity to improve this situation via electronic data sharing. These new technologies make possible new ways of working and collaboration but it can be difficult for health care organizations to understand how to adopt new technologies while still ensuring that their policies and objectives are being met. It is also important to have a systematic approach to validate that e-health processes deliver the performance improvements that are expected. Using a case study of a palliative care patient receiving home care from a team of collaborating healthcare providers and organizations, we introduce a framework for assessing health care information systems based on requirements engineering. Key concerns and objectives were identified and modeled. Business processes which will use the new health care information system are modeled in terms of these concerns and objectives to assess their impact and ensure that electronic data sharing is well regulated and effective. The work in the thesis is design-oriented research to show the utility of our proposed requirement engineering framework compared to existing evaluation approaches for healthcare IT. The approach is evaluated based on a set of criteria drawn from our literature review and a gap analysis of our case study for palliative care.
