Abstract Background Healthcare relies on health information systems (HISs) to support the care and receive reimbursement for the care provided. Healthcare providers experience many problems with their HISs due to improper architecture design. To support the design of a proper HIS architecture, a reference architecture (RA) can be used that meets the various stakeholder concerns of HISs. Therefore, the objective of this study is to develop and analyze an RA following well-established architecture design methods. Methods Domain analysis was performed to scope and model the domain of HISs. For the architecture design, we applied the views and beyond approach and designed the RA’s views based on the stakeholders and features from the domain analysis. We evaluated the RA with a case study. Results We derived the following four architecture views for HISs: The context diagram, decomposition view, layered view, and deployment view. Each view shows the architecture of the HIS from a different angle, suitable for various stakeholders. Based on a Japanese hospital information system study, we applied the RA and derived the application architecture. Conclusion We demonstrated that the methods of the software architecture design community could be used in the healthcare domain effectively and showed the applicability of the RA.

Positivist Approach

The rapid increase in investments for computerised systems is a major concern for all health organisations. Questions about these investments arise as information technologyis only one of the areas that are competing for a finite amount of resources. There is also some concern that some of the failures of information technology would have been detected if proper evaluation of information systems were conducted. The state of the art of evaluating information systems shows changes from a very positivist approach tomore comprehensive approaches that would incorporate multiple methods. This paperpresents an assessment of the techniques and methods for information systems evaluation, followed by an application to a case study in community health to illustrate the value of the contextualist approach to evaluation. The paper argues for the use of longitudinal, contextualist approaches to information systems evaluation if decision-makers seek to improve the situation of information systems in the health industry.

The Public

The use of Health Information Systems (HIS) is considered to be a major contributing factor to healthcare service delivery. However, the utilisation of HIS which includes use and management is critically challenging in the public health sector in many developing countries. The manifestation of the challenges results in poor service delivery, which includes patient deaths. This is the main motivation for this study, to investigate how HIS can be used to improve service delivering in the hospitals from developing countries perspective. The study was carried out in Namibia, using two hospitals in the public healthcare. The study adopted the qualitative case study. The study revealed that the use of parallel systems, lack of systems integration, lack of portable devices and users' incompetency are some of the factors which impact the use and management of HIS in hospitals.

Adaptive Structuration

Adaptive structuration theory (AST) is rapidly becoming an important theoretical paradigm for comprehending the impact of advanced information technologies. In this chapter, a modified AST model was designed to illustrate the changing interrelationships among the variables affecting the adoption and application of a new technology into a medical organization setting. Using findings from a case study conducted over a 10-month period, the authors apply the case to the model to illustrate the complex interactions between medical billing technology and organizational processes. As the organization attempted to install and implement the new system, it found that in order to maintain daily operations, it would have to modify and adapt several aspects of the organization, technology and operations. As the system was slowly integrated into operations and the organization’s needs evolved through the adaptation process, the study, in turn, found that different iterations of the model could emphasize different structures. The case illustrated that the capacity to manage health information systems (HIS) often requires the organization to prioritize its needs and focus its energies on a critical structure while temporarily disregarding others until the primary healthcare processes are under control.

Recent Trends

SummaryIn this paper two major tasks of health telematics are identified: telemedicine to support the physicians and collaborative health information systems additionally incorporating the patient. In the field of telemedicine, exemplary scenarios of teleconsultation/teletherapy but also the creation of joint electronic patient records by several healthcare providers are described in detail and analysed. Those are teleradiology, telepathology, and telesurgery. On the other side, collaborative health information systems provide several means to actively incorporate the empowered patient in the care process. We illustrate the approach of sharing a patient's electronic medical record with the patient and distinguish it from alternative approaches, such as email communications between patients and doctors or patient empowerment through web-based information services. For all such applications, recent trends in research and implementation are analysed and the technological as well as legal requirements are discussed.
