Background: On 26 December 2003, an earthquake measuring 6.5 on the Richter scale occurred in the city of Bam in southeastern Iran. Bam was destroyed completely, >43,000 people were killed, and 30,000 were injured. The national and international responses were quick and considerable. Many field hospitals were created and large numbers of patients were evacuated from their homes and transported to hospitals throughout Iran. Nearly 700 patients were transferred to Chamran hospital in Shiraz within the first 48 hours after the earthquake. Methods: This is a retrospective study based on the medical records of earthquake casualties dispatched to Chamran Hospital. A screening tunnel composed of multiple stations was prepared before patients entered to facilitate the large influx of patients. Each of the victims was passed through this screening tunnel and assigned into one of three groups: (1) those needing emergency surgical intervention; (2) those needing less urgent surgery; and (3) those needing elective operations, supportive care, observation, and/or rehabilitation. Results: Among the 708 patients, 392 were male (male/female ratio: 1.24) with a mean value of their ages of 30.5 years, (range: 1.5 months-70 years). Extremity fractures (136, 19%) were more common than were axial skeleton fractures (28, 4%). Out of the total 708 patients, 152 (21.5%) patients needed emergency operations, 26 (4%) needed less urgent surgery, and 530 (74.5%) required wound care or antibiotic therapy and other forms of supportive care. Some complications occurred, such as two patients with compartment syndromes of the leg, three required below-the-knee amputation, eight suffered acute renal failure, two developed fat emboli syndrome, and one had a brain injury that resulted in death. Conclusion: A comprehensive disaster plan is required to ensure a prompt disaster response and coordinated management of a multi-casualty incident. This can influence the outcomes of patients directly. A patient screening tunnel has advantages in rapid and effective evaluation and management of victims in any multi-casualty incident.
