SW architecture of clinical decision support service in prevention of falls

Abstract

A clinical decision support (CDS) service reduces errors in healthcare services and improves the quality and efficiency of healthcare by providing appropriate recommendations or alerts when needed. Owing to these advantages, the attempts to build a CDS service for each hospital, and for each ward in the hospital are increasing. In order to efficiently build multiple CDS systems, it is necessary to develop them into a CDS product line rather than a single CDS. That is, an architecture that can accommodate the variability of a CDS service to easily reflect the different requirements that need to be created. In this study, we designed an architecture that can support the building of a product line that addresses falls, which is the main management subject of each hospital, by applying an architecture-based design (ABD) technique. The applicability of the product line architecture was verified by additionally constructing CDS services to prevent falls in other hospitals based on the proposed architecture.
