Study objective: To evaluate emergency medical services (EMS) system use, injury mechanisms, and prehospita] assessments among elderly victims of trauma.
Design: We analyzed all prehospital data for injuries among patients 70 years old or older for whom 911 EMS dispatch was requested in a mediumsized metropolitan area during a 12-month period.
Results: A total of 1,154 cases occurred (women, 65.1%), which represented 30.3% of all 911 dispatches involving elderly patients. Injury mechanisms were fall (60.7%), motor vehicle accident (MVA; 21.5%), fight (2.4%), accidental poisoning (2.3%), and choking (2.1%). Persons in their 90s had a lower frequency of MVAs (3.4%) than did younger patients (23.0%) (P < .005). The most frequent injuries determined by prehospital assessment were head or face (25.1%), upper extremity (17.2%), hip (14.5%), lower extremity (13.8%), back (9.8%), and chest or abdomen (5.0%). The frequency of serious neurologic injuries was less for falls or MVAs than for other mechanisms (P < 1005). Suspected hip (P < .001) and pelvic (P < .005) injuries occurred more frequently during falls than during other mechanisms of injury, whereas back injuries occurred most frequently in MVAs (P < .001). Seventy-one fall victims (10.i%) had suspected medical causes of their fall. Twelve patients (1.0%) were in cardiac arrest.
Conclusion:
We report injury patterns and mechanisms among elderly victims of trauma presenting to an EMS system. A knowledge of these patterns will be useful to emergency physicians and EMS administrators.
