Risk analysis and safety assessment of hospitals against disasters: A systematic review

Both natural and man-made disasters are increasing in occurrence at the world. Hospitals and health-care centers are very complex and have a high potential for vulnerability depending on external and internal factors. Unfortunately, past experiences show that health-care centers and the health system are vulnerable to disasters. Therefore, risk analysis and safety assessment studies of hospitals and other health-care centers are absolutely necessary. This systematic review study was conducted on the basis of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. English language international databases (Pub Med, Scopus, Embase, Web of Science, and Google Scholar) were searched through January 1, 2000 up to June 20, 2019. The quality of the studies was assessed using the International Narrative Systematic Assessment tool. From 3630 titles identified in this search, 24 studies were selected. The important findings of this study were grouped into five main categories: risk analysis method, type of disaster, hospital safety methods, hospital components and key outcomes of risk analysis, and hospital safety assessments. The nature of disasters is a threat to the lives and property of the people, and therefore hospitals must be available at the incidents and disasters and they must be able to respond to the needs of the disaster-affected community. The probability of an incident and its consequences can never be reduced to zero; because the severity of many natural and even man-made disasters is unpredictable and the probability of their occurrence is different; however, it is possible to identify weaknesses and strengths through risk analysis studies as well as hospital safety assessments and implement retrofitting programs based on the type of risks and safety status and reduce the level of risk to an acceptable level.
