Summary Objectives: Several standards applied to the healthcare domain support semantic inter-operability. These standards are far from being completely adopted in health information system development, however. The objective of this paper is to provide a method and suggest the necessary tooling for reusing standard health information models, by that way supporting the development of semantically interoperable systems and components. Methods: The approach is based on the definition of UML Profiles. UML profiling is a formal modeling mechanism to specialize reference meta-models in such a way that it is possible to adapt those meta-models to specific platforms or domains. A health information model can be considered as such a meta-model. Results: The first step of the introduced method identifies the standard health information models and tasks in the software development process in which healthcare information models can be reused. Then, the selected information model is formalized as a UML Profile. That Profile is finally applied to system models, annotating them with the semantics of the information model. The approach is supported on Eclipse-based UML modeling tools. The method is integrated into a comprehensive framework for health information systems development, and the feasibility of the approach is demonstrated in the analysis, design, and implementation of a public health surveillance system, reusing HL7 RIM and DIMs specifications. Conclusions: The paper describes a method and the necessary tooling for reusing standard healthcare information models. UML offers several advantages such as tooling support, graphical notation, exchangeability, extensibility, semi-automatic code generation, etc. The approach presented is also applicable for harmonizing different standard specifications.

The Impact

The purpose of this paper is to argue for an integration of cognitive and socio-technical approaches to assessing the impact of health information systems. Historically, health informatics research has examined the cognitive and socio-technical aspects of health information systems separately. In this paper we argue that evaluations of health information systems should consider aspects related to cognition as well as socio-technical aspects including impact on workflow (i.e. an integrated view). Using examples from the study of technology-induced error in healthcare, we argue for the use of simulations to evaluate the cognitive-socio-technical impacts of health information technology [36]. Implications of clinical simulations and analysis of cognitive-social-technical impacts are discussed within the context of the system development life cycle to improve health information system design, implementation and evaluation.

Summary Objectives: While recognized that global actors influence health information system design, studies of health informatics have largely focused on micro politics of technology design and implementation. Here a problematic patient care information system (PCIS) is discussed in relation to federal and provincial policies and corporate strategies to demonstrate that our understanding of health informatics can be enhanced by linking micro studies of health informatics to larger macro contexts. Methods: Interviews and document study. Results: Although the extent to which federal initiatives influenced (or failed to influence) provincial and hospital initiatives remains debateable, events initiated at one level (the hospital’s decision to implement software, initiated at the organizational level) are influenced (perhaps indirectly) by developments in other contexts (federal /macro changes gave an initiative more weight; provincial initiatives such as the Labour Accord altered the industrial relations environment in which system development occurred). Conclusions: Micro-studies of work practice, invaluable in addressing interactions between technologies, users and work practices, often fail to account for the historic reach of global actors, although it is often these historic circumstances that contribute to present-day interactions between user, information system and organization, and that find expression – often indirectly – in daily work practices.

The Community Health Information Development (CHID) Project, a project for NSW Health, was initiated in August 1994. The goal of CHID was to assess the feasibility of an information system for this sector of the NSW health system which could answer questions on the business functions, performance measurement, service planning and service quality of community health. An organisational structure and process were developed by October 1994. That organisational structure and process were utilised for the assessment of the community health environment to determine the feasibility of, and requirements for, a community health information system. A brief overview of the four interrelated Working Parties' findings: Service Domains; Common Data Set; Information Management; and, Information Technology is provided. The key concepts in the Community Health Information Model (CHIM), a deliverable of the Information Management Strategy, is then outlined. This model, built through extensive consultation with community health workers, is accompanied by a dictionary which outlines each community health entity and attribute. The Community Health Information Model has 230 entities, approximately 485 attributes and 357 relationships between those entities and attributes and provides a common language for communication within community health. An overview of the Community Health Function Model, a companion model for the CHIM, is then provided. A Function Model describes the processes which generate the entities and attributes in an Information Model. The Function Model is also used to inform the scope of information system development, the next phase of this project. Following completion of the assessment phase in November 1994, a Business Case for the development of an information system for community health was accepted by the executive of NSW Health (the NSW health department). The paper outlines briefly, progress on the development of the information system and the proposed timeline for implementation.

Objective. This article objective is to highlight implementation characteristics, concerns, or limitations over role-based access control (RBAC) use on health information system (HIS) using industry-focused literature review of current publishing for that purpose. Based on the findings, assessment for indication of RBAC is obsolete considering HIS authorization control needs. Method. We have selected articles related to our investigation theme “RBAC trends and limitations” in 4 different sources related to health informatics or to the engineering technical field. To do so, we have applied the following search query string: “Role-Based Access Control” OR “RBAC” AND “Health information System” OR “EHR” AND “Trends” OR “Challenges” OR “Security” OR “Authorization” OR “Attacks” OR “Permission Assignment” OR “Permission Relation” OR “Permission Mapping” OR “Constraint”. We followed PRISMA applicable flow and general methodology used on software engineering for systematic review. Results. 20 articles were selected after applying inclusion and exclusion criteria resulting contributions from 10 different countries. 17 articles advocate RBAC adaptations. The main security trends and limitations mapped were related to emergency access, grant delegation, and interdomain access control. Conclusion. Several publishing proposed RBAC adaptations and enhancements in order to cope current HIS use characteristics. Most of the existent RBAC studies are not related to health informatics industry though. There is no clear indication of RBAC obsolescence for HIS use.

Summary Objectives: To illustrate the advantages of an open-ended formative evaluation approach using a project-specific selection of methods over the controlled trial approach in the evaluation of health information systems. To illustrate factors leading to success and others impeding it in a telehealth project. Methods: The methods and results of an evaluation of the BC Telehealth Program are summarized. Results: The evaluation gave a comprehensive picture of the project, including assessment of the effects of an array of telehealth applications, and their economic impact. Factors leading to success and others preventing it are identified from the level of overall program management to the project specifics. The results include unanticipated effects and explanations for their reasons of occurrence. Neither the comprehensiveness of information nor the timeliness was achieved in a related project using a controlled trial approach. Conclusions: Not all types of health information system projects can be evaluated using the controlled trial approach. This approach may impede important insights. It is also usually much less efficient. Funding agencies and journal editors have to take this into account when selecting projects for funding and submissions for publication.

Genetic programming (GP) is known to provide good solutions for many problems like the evolution of network protocols and distributed algorithms. In most cases it is a hardwired module of a design framework assisting the engineer in optimizing specific aspects in system development. In this article, we show how the utility of GP can be increased remarkably by isolating it as a component and integrating it into the model-driven software development process. Our GP framework produces XMI-encoded UML models that can easily be loaded into widely available modeling tools, which in turn offer code generation as well as additional analysis and test capabilities. We use the evolution of a distributed election algorithm as an example to illustrate how GP can be combined with model-driven development (MDD).

Abstract:The paper attempts to derive directions for research and teaching in health informatics. To this end, the achievements and continuing challenges of health informatics are exemplified, categorized, and related to common underlying phenomena. Suggestions by Blum and Blois are adopted which point to the complexity of health information as the critical ingredient. Examples are given of current efforts directed at dealing with this complexity. According to Popper and Brookes one may have to search for yet other ways of dealing specifically with information; we have barely started to explore these. It is suggested that this requirement for a fundamentally different orientation has profound consequences not only for our research but also for our teaching.
