    Abstract:
    BACKGROUND: The incidence of large-scale urban attacks on civilian populations has significantly increased across the globe over the past decade. These incidents often result in Hospital Multiple Casualty Incidents (HMCI), which are very challenging to hospital teams. 15 years ago the Emergency and Disaster Medicine Division in the Israeli Ministry of Health defined a key of 20 percent of each hospital's bed capacity as its readiness for multiple casualties. Half of those casualties are expected to require immediate medical treatment. This study was performed to evaluate the efficacy of the current readiness guidelines based on the epidemiology of encountered HMCIs. METHODS: A retrospective study of HMCIs was recorded in the Israeli Defense Force (IDF) home front command and the Israeli National Trauma Registry (ITR) between November 2000 and June 2003. An HMCI is defined by the Emergency and Disaster Medicine Division in the Israeli Ministry of Health as >or=10 casualties or >or=4 suffering from injuries with an ISS>or=16 arriving to a single hospital. RESULTS: The study includes a total of 32 attacks, resulting in 62 HMCIs and 1292 casualties. The mean number of arriving casualties to a single hospital was 20.8+/-13.3 (range 4-56, median 16.5). In 95% of the HMCIs the casualty load was <or=52. Based on severity scores and ED discharges 1022 (79.2%) casualties did not necessitate immediate medical treatment. CONCLUSION: Hospital preparedness can be better defined by a fixed number of casualties rather than a percentile of its bed capacity. Only 20% of the arriving casualties will require immediate medical treatment. Implementation of this concept may improve the utilisation of national emergency health resources both in the preparation phase and on real time.
