  1. Long-term survival of elderly trauma patients.

    Article - En anglais


    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.

    Data Sources 

    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.

    Main Outcome Measures 

    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. (...)
