0997 Scheduling Factors Associated With Resident Physician And Patient Safety In More Senior Residents

Abstract

Introduction: Long work hours and extended-duration (>=24 hours) work shifts are associated with higher risks of motor vehicle crashes (MVCs), near-crashes, percutaneous injuries (PIs), medical errors, and adverse events among resident physicians in their first postgraduate year (PGY1). We sought to determine if these same associations were present in more senior resident physicians (PGY2 and above). Method(s): All medical students who matched to a United States residency program from 2002-2007 and 2014-2017 were invited to participate in a prospective cohort study. Each month, participants reported hours of work (including time in patient care), extended duration shifts, and adverse safety outcomes; including MVCs, near-crashes, PIs, medical errors and adverse events. We pooled data from both cohorts and tested the association between work hour characteristics and adverse safety outcomes using generalized linear models adjusted for potential confounders. Result(s): Monthly reports were completed by 4,826 more senior resident physicians (38,702 resident-months). We observed a significant dose-response relationship between weekly work hours and the risk of adverse safety outcomes (p <0.001). There was a significant dose-response relationship between the number of extended duration shifts and the risk of adverse patient safety outcomes (p
