FREQUENCY, DISTRIBUTION, AND MANAGEMENT OF INJURIES DUE TO AN ICE STORM IN A LARGE METROPOLITAN-AREA

Patterns of injuries seen in the emergency department (ED) following a n ice storm were evaluated and compared to those seen during a control snow period. We conducted a retrospective chart review for an 11-day ice period and an 11-day control snow period using charts from eight m etropolitan area EDs. Charts were reviewed for all patients with compl aints of falls, motor vehicle crashes (MVCs), or sledding accidents du e to ice or snow conditions. The numbers of injuries resulting from fa lls, MVCs, and sledding accidents for patients of various ages during each of the two periods were compared by chi-square analysis. Of 1,631 patients seen during the 11-day ice period, 1,181 (72%) had injuries due to falls, 192 (12%) were injured in MVCs, and 232 (14%) suffered s ledding injuries. Falls on ice resulted in a fracture 39% of the time, whereas MVCs resulted in fracture 14% of the time. Falls accounted fo r 90% of the fractures during the ice period versus 76% during the sno w period. The risk of sustaining a fracture as a result of a fall was significantly higher in older age groups (relative risk [RR] = 2.1), a s was the risk of hospitalization (RR = 2.3). There was a significant increase in the number of falls and sledding accidents during the ice period. Thus, ice coverage resulted in a significant increase in fall- related and sledding-related fractures requiring treatment in the ED.
