This was a retrospective study that aimed to determine the treatment outcome of patients seen in the trauma unit of the Johnson City Medical Center (JCMC). The study included 2844 patients in the trauma registry and evaluated age, sex, injury severity score (ISS), length of stay (LOS) in the intensive care unit (ICU), overall hospital lengths of stay (LOS), ventilator days, discharge disposition, and complications between one group managed by extenders only and the second managed by both residents and extenders. The sample size of the two groups was similar (group one = 1446 and group two = 1398) and the proportions of males and females in the two groups were identical (males = 65%, females = 35%). Both groups had similar mechanisms of injury, although group one had a higher percentage of falls (32.9% vs. 22.03%) and group two had a higher proportion of motor vehicle crash (MVC) traumas (40.41% vs 30%). There was no significant difference in those discharged home and deaths between the two groups. (χ(1, N = 2258) = 0.04, p = 0.82). Complications showed statistical significance when looking at extenders vs. residents plus extenders for all complications (χ(7, N = 196) = 38.73, p ≤ 0.0001). It is possible that having extenders only versus both extenders and residents had no significant difference among the patient outcomes based on the variables age, sex, ISS, ICU days, overall hospital LOS, and ventilator days; however, when observing complications between the two groups, it is possible that patients are more likely to have complications due to overall hospital LOS in the residents plus extenders group.
