Interoperability standards in Health Information Systems

Introduction: Health Information Systems (HIS) have been improved to enhance the quality of healthcare. However, adequate computerization of these systems, as demanded by the digital society, requires the adoption of interoperability standards that allow all system elements to be interconnected. Objective: to describe the results provided by the literature on the use of interoperability standards in HIS. Methods: a systematic review was conducted using the PRISMA methodology on the results of the adoption of interoperability standards in HIS. Information was searched in Scopus, Medline, Google Scholar, and SciELO. Then, a selection of the most relevant studies was made, using inclusion criteria. Results: most of the reviewed studies focused on the evaluation of interoperability standards in hospital and institutional environments, with a global interest in such standards. The diversity of standards used and the results obtained demonstrate the importance and significant impact of the implementation of interoperability standards in improving the quality of healthcare systems. Conclusions: the systematic literature review reveals that the implementation of interoperability standards is fundamental to ensure the integration between the components that make up the systems, which in turn contributes to operational efficiency and information security
