Abstract

BACKGROUND: The "July Phenomenon" refers to the propensity for increased errors to occur with new housestaff, as they assume new responsibilities at the beginning of the academic year. The purpose of this study was to examine the impact of the new residents presenting in July at a high volume Level I Academic Trauma Center. METHODS: The trauma registry at the Los Angeles County + University of Southern California Medical center was retrospectively reviewed to identify all injured patients admitted over a 5-year period ending in December 2006. All Morbidity and Mortality reports for the study period were reviewed to extract deaths and any complications classified as preventable or potentially preventable. Patients admitted in the first 2 months (July to August) of the academic year were compared with those treated at the end of the academic year (May to June). Baseline clinical and demographic characteristics were compared, and the rates of preventable and potentially preventable deaths and complications were determined for each of these groups. RESULTS: During the 5-year study period, 24,302 injured patients were admitted. Of those, 8,151 were admitted during the period from May to August with 4,030 (49.4%) at the beginning of the academic year (July to August) and 4,121 (50.6%) at the end of the academic year (May to June). Overall, the average age was 35.1 +/- 17.7 years, 77% were men with an Injury Severity Score of 8.4 +/- 9.7 and 24.2% penetrating injury rate. When examining mortality, after adjustment for differences between the two groups, there was no difference between patients admitted at the beginning or at the end of the academic year (adjusted odds ratio 95% confidence interval.: 1.1 0.8, 1.5., p = 0.52). However, when compared with the patients treated for their injuries in May to June, those treated at the beginning of the academic year had a significantly higher rate of preventable and potentially preventable complications (adjusted odds ratio 95% confidence interval.: 1.9 1.1, 3.2., p = 0.013). CONCLUSIONS: At an academic Level I trauma center, admission at the beginning of the academic year was associated with an increased risk of errors resulting in preventable and potentially preventable complications; however, these errors did not impact mortality. Specific errors associated with this increased rate of preventable complications warrant further investigation.
