A statewide analysis of level I and II trauma centers for patients with major injuries

This study examines statewide outcomes and resource use in Level I and II trauma centers for patients with major injuries.

This study analyzed trauma registry data on patients admitted to North Carolina Level I and II trauma centers from January 1995 to December 1996 with one of four major injuries: thoracic aortic disruption, liver injury, pelvic fracture, or pulmonary contusion.

There were 59 thoracic aortic disruptions, 109 liver injuries, 153 pelvic fractures, and 962 pulmonary contusions identified among 26,030 admissions. Case fatality was not significantly different (Level I, 16.8%; Level II, 14.9%). Hospital charges were significantly higher in Level I centers (Level I, $47,366; Level II, $35,490), but this difference was confined to transferred patients. Controlling for Revised Trauma Score, Injury Severity Score, age, gender, and race, multivariable regression confirmed findings regarding hospital charges, and multiple logistic regression confirmed findings regarding case fatality.

Case fatality was similar in Level I and Level II trauma centers in North Carolina, and hospital charges were comparable in patients with comparable injuries not requiring transfer. This suggests that patients with major injuries may be optimally cared for in both Level I and Level II trauma centers.
