The Development and Implementation of Patient Safety Information Systems (PSIS)

Abstract

This chapter presents the overview of the current status and developmental stages of the PSIS technology and consensus around the patient safety issues as they emerge, grow, and mature globally. The first section gives the general description of the patient safety reporting system (PSRS), and then provides the brief summary of 23 patient safety information classifications and terminologies to date. In the next section, the development of the international classification of patient safety (ICPS) is overviewed, which evolved from the local to an international level by the joint initiatives of WHO. The essential elements of the PSIS and the clinical decision support system (CDSS) functionalities are explained to make the future goals of PSIS clearer. The patient safety indicator (PSI) is explained in a separate section, which provides the opportunity to assess the incidence of adverse events and in-hospital complications using administrative data found in the typical discharge record. The ultimate goals of PSIS and PSI are to improve the quality of healthcare and ensure patient safety.
