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.

Patient Safety Reporting System

There are many ways to improve patient safety using information technology (Bates & Gawande, 2003). One way of improving safety is improving detection and reporting systems for error and adverse event (IOM, 2003). In small studies, computerized reporting systems have been associated with an increased rate of spontaneous reporting (Dixon, Wielgosz, & Pires, 2002). Computerized reporting streamlines subsequent evaluation by making it is easier to perform analyses and categorize reports in different ways. One university hospital treating more than 25,000 patients annually reported a feasibility study of a computerized voluntary based medical error reporting system in the ambulatory setting (Plews-Ogan et al., 2004). The findings showed that the voluntary based medical error reporting system resulted in a 20-fold increased reporting rate, and physicians reported many of these errors. Also the study suggested that new medical error reporting systems should combine reporting with analytic functions to facilitate analysis. A study by Furakawa et al from Japan found that a computerized medical error reporting system was effective and acceptable to providers, and facilitated analysis (Furukawa, Bunko, Tsuchiya, & Miyamoto, 2003). In another study, a web-based reporting system was developed and implemented for medical workers of 54 hospitals who were working in neonatal intensive care units (Suresh et al., 2004). This system was both voluntary and anonymous. Evaluation of the feasibility and utility of this approach revealed that it was well received, and effective for identifying a wide variety of medical errors. In addition, the approach facilitated cooperative, multidisciplinary studies.
