In-hospital resource utilization during multiple casualty incidents

Objective: To suggest guidelines for hospital organization during terror-related multiple casualty incidents (MCIs) based on the experience of 6 level I trauma centers. Summary Background Data: Most terror-related MCIs are bombings. The sporadic nature of these events complicates in-hospital preparation. Methods: Data were collected at all level I Trauma centers during/after MCIs for the Israel National Trauma registry. Patients were included if they were admitted or died in hospital following injury in suicide bombings (October 1, 2000 to June 30, 2003), which fulfilled Ministry of Health suggested criteria for MCIs (number of admissions, severity of injury). Results: Included were 325 casualties from 32 events, 34% of which had an Injury Severity Score >16. A third of the admissions arrived within 10 minutes and 65% within 30 minutes. Forty percent of the patients underwent CT scans directly from the ED. Operative procedures were performed on 60% of patients and 36% were transferred directly from the ED to the OR. Initiation of surgical procedures peaked at 1 to 1.5 hours, mainly multidisciplinary abdominal, thoracic, and vascular surgery. Orthopedic and plastic surgery predominated later. A third of the patients were admitted to ICUs, often (31%) directly from the ED. Conclusions: High staffing demands for ED, OR, and ICU overlap. Anesthesiologists, general, thoracic, and vascular surgeons are in immediate demand. ICU admissions occur simultaneously with ongoing patient arrival to the ED. Most patients operated within the first 2 hours require multidisciplinary surgical teams. Demand for orthopedic and plastic surgery and anesthesiology services continues for >24 hours.
