Most of these problems occur when relevant standards, procedures, and guidelines are not followed effectively.īecause HISs consist of many interrelated software modules that should communicate, coordinate, and evolve over time, the software architecture is critical in HIS design. Other studies on HISs reported problems with poor interface design, poor security, missing features, lack of professional support, limited use, and low data quality. For example, lack of interoperability resulting in care professionals having difficulty communicating files. Unfortunately, current HISs still have some drawbacks. Examples of functionalities are financial management, daily reporting, and medication management. Healthcare relies on health information systems (HISs) to support various care processes and receive reimbursement for the care provided. 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. Based on a Japanese hospital information system study, we applied the RA and derived the application architecture. Each view shows the architecture of the HIS from a different angle, suitable for various stakeholders. We derived the following four architecture views for HISs: The context diagram, decomposition view, layered view, and deployment view. 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. Methodsĭomain analysis was performed to scope and model the domain of HISs. Therefore, the objective of this study is to develop and analyze an RA following well-established architecture design methods. To support the design of a proper HIS architecture, a reference architecture (RA) can be used that meets the various stakeholder concerns of HISs. Healthcare providers experience many problems with their HISs due to improper architecture design. Healthcare relies on health information systems (HISs) to support the care and receive reimbursement for the care provided.
