To evaluate the long-term survival and factors that influence survival among a cohort of elderly trauma patients compared with an uninjured cohort.
A retrospective cohort analysis.
Health Care Finance Administration, Bal-timore, Md, Medicare data.
A cohort of elderly patients (n=9424) hospitalized for injury in 1987 was identified using Medicare hospital discharge abstract data.
An uninjured comparison group (n=37 787) was identified from Medicare eligibility files.
For injured patients, an Injury Severity Score was generated from the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9CM) codes.
For both cohorts, preexisting illness was assessed by ICD-9CM codes from Health Care Finance Administration outpatient and inpatient data files for 1986 and 1987.
Relative risk for mortality within 5 years subsequent to injury, adjusted for age, sex, and preexisting illness, using Cox proportional hazard regression.
The injured cohort had a significantly reduced 5-year survival when compared with the uninjured group (relative risk [RR]=1.71 ; 95% confidence interval, 1.66-1.77).
The lower survival persisted even among patients who survived at least 3 years after injury.
Coexisting disease, age, and Injury Severity Score were strong predictors of survival. (...)
