C-20 | Higher Amputation Rates Among Patients Admitted to United States Teaching Hospitals in the Month of July: The July Effect

Every year, teaching hospitals in the United States experience a turnover trainees. Several studies have shown an increase adverse outcomes and higher resource utilization during beginning of academic year compared to end year. We hypothesized that patient hospitalizations month July would poorer those May. National Inpatient Sample 2018 was queried with ICD-10-CM codes identify admissions months Outcomes interest including inpatient mortality, amputation rates mean length stay (LOS) were between two groups. A multivariate logistic regression analysis performed while adjusting for confounders analyze our calculate adjusted odds ratio (aOR) corresponding 95% confidence interval (CI). total 5,560 weighted (48.1%) May (51.9%) identified. Average age 70 years 37.8% females. Hospital associated (aOR 1.33; 1.01 - 1.75, p=0.04), particularly major amputations 1.50; 1.08-2.1, p=0.02) There non-statistically significant trend towards LOS (+0.77 days; -0.58 1.59, p=0.07) admissions. No difference found mortality such effect observed terms mortality.
