A five-year experience with severe injuries in elderly patients.

Recent reports of injury in elderly patients document that aggressive care is justified. Our experience indicates that geriatric injury differs from that of other trauma patients. All patients entered into a large urban trauma center registry over a five-year period were analyzed. Variables reviewed included demographics, trauma indices, mechanism of injury, mean number of hospital days, and morbidity and mortality for patients under 60 years old and for geriatric patients defined as those aged 60 and above. There were 3,064 patients in the reviewed group, of whom 243 qualified for geriatric analysis. Blunt injuries in males were the most typical scenario. Failure to use safety belts and alcohol intoxication persist into the geriatric age group (83% and 13%, respectively). Trauma indices including Injury Severity Score (ISS) were slightly greater in the geriatric group (27 versus 23) as compared to younger patients; plus geriatric patients tolerated head injury less well (GCS in those who died 6.7 versus 4.6, respectively; p < 0.001). Mortality in the geriatric group was 31% while being 17.1% in the younger group (p < 0.005). Days in the hospital were 20 for the geriatric compared to 13 for the younger group (p < 0.025). Infections and chest complications were twice as common in the elderly and dysrhythmias were five times more frequent. Elderly patients constitute 8% of the trauma population and suffer a magnitude of injury at least comparable to the general population. Their mortality is approximately 50% above the population as a whole and morbidity twice as common, accounting for the prolonged hospital stay.
