Background: Analysts have warned on multiple occasions that hospitals are potential soft targets for terrorist attacks. Such attacks will have far-reaching consequences, including decreased accessibility, possible casualties, and fear among people. The extent, incidence, and characteristics of terrorist attacks against hospitals are unknown. Therefore, the objective of this study was to identify and to characterize terrorist attacks against hospitals reported to the Global Terrorism Database (GTD) over a 50-year period. Methods: The GTD was used to search for all terrorist attacks against hospitals from 1970-2019. Analyses were performed on temporal factors, location, attack and weapon type, and number of casualties or hostages. Chi-square tests were performed to evaluate trends over time and differences in attack types per world region. Results: In total, 454 terrorist attacks against hospitals were identified in 61 different countries. Of these, 78 attacks targeted a specific person within the hospital, about one-half (52.6%) involved medical personnel. There was an increasing trend in yearly number of attacks from 2008 onwards, with a peak in 2014 (n = 41) and 2015 (n = 41). With 179 incidents, the “Middle East & North Africa” was the most heavily hit region of the world, followed by “South Asia” with 125 attacks. Bombings and explosions were the most common attack type (n = 270), followed by 77 armed assaults. Overall, there were 2,746 people injured and 1,631 fatalities. In three incidents, hospitals were identified as secondary targets (deliberate follow-up attack on a hospital after a primary incident elsewhere). Conclusion: This analysis of the GTD identified 454 terrorist attacks against hospitals over a 50-year period. It demonstrates that the threat is real, especially in recent years and in world regions where terrorism is prevalent. The findings of this study may help to create or further improve contingency plans for a scenario wherein the hospital becomes a target of terrorism.

Background Internal hospital crises and disasters (IHCDs) are events that disrupt the routine functioning of a hospital while threatening the well-being of patients and staff. IHCDs may cause hospital closure, evacuations of patients and loss of healthcare capacity. The consequences may be ruinous for local communities. Although IHCDs occur with regularity, information on the frequency and types of these events is scarcely published in the medical literature. However, gray literature and popular media reports are widely available. We therefore conducted a scoping review of these literature sources to identify and characterize the IHCDs that occurred in Dutch hospitals from 2000 to 2020. The aim is to develop a systematic understanding of the frequency of the various types of IHCDs occurring in a prosperous nation such as the Netherlands. Methods A systematic scoping review of news articles retrieved from the LexisNexis database, Google, Google News, PubMed and EMBASE between 2000 and 2020. All articles mentioning the closure of a hospital department in the Netherlands were analyzed. Results A total of 134 IHCDs were identified in a 20-year time period. Of these IHCDs, there were 96 (71.6%) emergency department closures, 76 (56.7%) operation room closures, 56 (41.8%) evacuations, 26 (17.9%) reports of injured persons, and 2 (1.5%) reported casualties. Cascading events of multiple failures transpired in 39 (29.1%) IHCDs. The primary causes of IHCDs (as reported) were information and communication technology (ICT) failures, technical failures, fires, power failures, and hazardous material warnings. An average of 6.7 IHCDs occurred per year. From 2000–2009 there were 32 IHCDs, of which one concerned a primary ICT failure. Of the 102 IHCDs between 2010–2019, 32 were primary ICT failures. Conclusions IHCDs occur with some regularity in the Netherlands and have marked effects on hospital critical care departments, particularly emergency departments. Cascading events of multiple failures transpire nearly a third of the time, limiting the ability of a hospital to stave off closure due to failure. Emergency managers should therefore prioritize the risk of ICT failures and cascading events and train hospital staff accordingly.

Introduction Emergency departments (EDs) are reasonably well prepared for external disasters, such as natural disasters, mass casualty incidents, and terrorist attacks. However, crises and disasters that emerge and unfold within hospitals appear to be more common than external events. EDs are often affected. Internal hospital crises and disasters (IHCDs) have the potential to endanger patients, staff, and visitors, and to undermine the integrity of the facility as a steward of public health and safety. Furthermore, ED patient safety and logistics may be seriously hampered. Methods Case series of 3 disasters within EDs. Narrative overview of the current IHCD-related literature retrieved from searches of PubMed databases, hand searches, and authoritative texts. Discussion The causes of IHCDs are multifaceted and an internal disaster is often the result of a cascade of events. They may or may not be associated with a community-wide event. Examples include fires, floods, power outages, structural damage, information and communication technology (ICT) failures, and cyberattacks. EDs are particularly at-risk. While acute-onset disasters have immediate consequences for acute care services, epidemics and pandemics are threats that can have long-term sequelae. Conclusions Hospitals and their EDs are at-risk for crises and their potential escalation to hospital disasters. Emerging risks due to climate-related emergencies, infectious disease outbreaks, terrorism, and cyberattacks pose particular threats. If a hospital is not prepared for IHCDs, it undermines the capacity of administration and staff to safeguard the safety of patients. Therefore, hospitals and their EDs must check and where necessary enhance their preparedness for these contingencies.

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.
