Abstract
To determine if a change in trauma designation from level II (L2) to level I (L1) in the same institution reduces mortality. A retrospective cohort study of all patients consecutively admitted to a community hospital trauma center. The upgrade to trauma L1 designation (January 1, 2003-March 31, 2007) (n = 7902) from trauma L2 designation (January 1, 1998-December 31, 2002) (n = 9511). Adjusted overall mortality and adjusted mortality for severely injured patients, patients with complications, and patients with severe sites of injury. After adjusting for age, sex, Injury Severity Score, mechanism of injury, hypotension on admission, respirations, and comorbidities, there was a significant decrease in overall mortality during L1 designation compared with L2 designation (2.50% vs 3.48%; P = .001). Severely injured patients (Injury Severity Score of >/= 15) admitted during an L1 trauma designation had a significant reduction in mortality compared with patients admitted during an L2 designation (8.99% vs 14.11%; P < .001). Patients admitted during an L1 designation with a severe head, chest, or abdominal or pelvic injury diagnosis had a significant decrease in mortality (9.96% vs 14.51% [P = .005], 7.14% vs 11.27% [P = .01], and 6.7...Continue Reading
