BackgroundMultiple studies have compared young and elderly blunt trauma patients, and concluded that, because elderly patients have outcomes similar to young patients, aggressive resuscitation should be offered regardless of age. Similar data on penetrating trauma patients are limited.Study DesignIn a retrospective review, 79 patients with penetrating injuries and age > or =55 were blindly matched for Injury Severity Score (ISS) and Abbreviated Injury Scores (AIS) with 79 penetrating trauma patients aged 15-35 years, who were admitted to the hospital over the same 4 year period (June 1994-June 1998). Mortality rates and length of stay in the intensive care unit (ICU) and the hospital were compared between the two groups.ResultsThe average ISS for all patients was 12 (range 1-75) and identical for both groups. Both groups had similar injuries and were evaluated by an equal number and type of diagnostic studies. The mean ISS was not different between severely injured older and younger patients who required ICU admission or died. Among 32 nonsurvivors (18 older and 14 younger), older patients were more likely than younger patients to present with normal vital signs, although the comparison did not reach statistical significance (50% vs. 13%, P=0.25). There was a clinically significant trend for longer ICU (15+/-30 vs. 3+/-2 days, P=0.096) and hospital stay (10+/-18 vs. 6+/-8 days, P=0.08) among older patients, but mortality rates were similar (23% in older vs. 18% in younger, P=NS). Furthermore, these outcome parameters showed no difference when both groups were classified according to severity of injury or physiologic response.ConclusionsFollowing penetrating trauma, older patients arriving alive and admitted to the hospital are as likely to survive as younger patients who have injuries of similar severity, but at the expense of longer ICU and hospital stays.
