To evaluate in-hospital, 1-year, and 5-year survivorship of geriatric patients after high-energy trauma, to compare survivorship of geriatric patients who sustained high-energy trauma with that of those who sustained low-energy trauma, and to identify predictors for mortality.




Urban Level I trauma center.


Study group of 1849 patients with high-energy trauma and comparison group of 761 patients with low-energy trauma.


Each patient was observed from the time of index admission through the end of the study period or until death or readmission.

Main Outcome Measurement:

Long-term survivorship based on the Social Security Death Index.


Survivorship between patients with high-energy and low-energy injuries was statistically significant. Among patients who sustained high-energy injuries, in-hospital mortality was 8%, 1-year mortality was 15%, and 5-year mortality was 25%. Among patients who sustained low-energy injuries, in-hospital mortality was 3%, 1-year mortality was 23%, and 5-year mortality was 40%. Low-energy mechanism of injury was an independent predictor for 1-year and 5-year mortality, even when controlling for Charlson Comorbidity Index (CCI), Injury Severity Score (ISS), age, sex, body mass index (BMI), and admission Glasgow Coma Scale (GCS) score.


Geriatric patients with high-energy injuries and those with low-energy injuries seem to represent different patient populations, and low-energy mechanism seems to be a marker for frailty. High-energy mechanism was associated with lower long-term mortality rates, even when controlling for CCI, ISS, age, sex, BMI and admission GCS score.

Level of Evidence:

Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
