Background: Hospitals are expected to provide their essential services under all circumstances, including disasters and crisis situations. However, crises and disasters may disrupt essential hospital functions, and necessitate evacuation of the facility. Data on the prevalence and causes of hospital evacuations is limited, whilst realistic evacuation planning will make hospitals more resilient during future crises and disasters. The aim of this study was to develop a systematic understanding of hospital evacuation frequency, causes and characteristics in the Netherlands. Methods: A systematic scoping review of news articles retrieved from the LexisNexis database, Google, Google News, PubMed and EMBASE between 1990 and 2020. All articles mentioning a hospital evacuation in the Netherlands were analyzed. Results: A total of 67 hospital evacuations were identified in a 30-year time period. The most common primary incidents were internal fire (33%), technological failure (21%) and hazardous materials (12%). Cascading events transpired in 37% of all events. As a result, internal fire (34%), internal power failure (19%) and hazardous materials (16%) were the most important reasons to evacuate a medical facility. The number of evacuees ranged from 1 to 339 patients (median 10.5, interquartile range 36), and there were 13 (19%) complete hospital evacuations. The frequency of hospital evacuations increased over time, with a more diverse etiology during later years. Conclusions: Hospital evacuations do occur, and hospitals are vulnerable to both internal and external hazards. Internal fire, internal power failure, hazardous materials and flooding incidents were the most important reasons to (partly) evacuate a hospital. Our findings suggest that facility-specific evacuation guidelines are necessary, and that evacuation preparedness will benefit if the most relevant evacuation scenarios are planned and practiced.
