Title: Socio-technical probabilistic risk assessment: Its application to patient safety
Author: Hale, M; Slonim, A; Allen, B; Marx, D; Kirkland, J
Abstract: In 1999, the Institute of Medicine released its watershed report that put the public on notice of the 44,000 to 98,000 deaths in US hospitals arising from errors in hospitals each year. In partial response, the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) has required each accredited hospital to conduct at least one proactive risk assessment annually. JCAHO recommended Failure Modes and Effects Analysis (FMEA) as one tool for conducting this task. This article examines the limitations of FMEA and introduces a socio-technical version of probabilistic risk assessment that has been applied recently within the commercial aviation, space shuttle, and healthcare operations environments. Within healthcare, this adapted tool, known as Socio-Technical Probabilistic Risk Assessment (ST-PRA), provides one additional alternative for pro-actively identifying, prioritizing, and mitigating patient safety risk. While ST-PRA is a complex, high-end risk-modeling tool, it provides an opportunity to visualize system risk in a manner not possible through root cause analysis, failure modes and effects analysis, or other qualitative methods.
