Medical resident sleep time reduces harmful errors

 Here's a new study of the effect on patient safety of the limitation on resident work hours to no more than 16 hour shifts, which was in effect in the US from 2011 to 2017.

National improvements in resident physician-reported patient safety after limiting first-year resident physicians’ extended duration work shifts: a pooled analysis of prospective cohort studies  BMJ Quality & Safety Published Online First: 10 May 2022. doi: 10.1136/bmjqs-2021-014375by Matthew D   Weaver1,2, Christopher P Landrigan1,3,4, Jason P Sullivan1, Conor S O'Brien1, Salim Qadri1, Natalie Viyaran1, Charles A Czeisler1,2, Laura K Barger1,2

Abstract: Background The Accreditation Council for Graduate Medical Education (ACGME) enacted a policy in 2011 that restricted first-year resident physicians in the USA to work no more than 16 consecutive hours. This was rescinded in 2017.

Methods "We conducted a nationwide prospective cohort study of resident physicians for 5 academic years (2002–2007) before and for 3 academic years (2014–2017) after implementation of the 16 hours 2011 ACGME work-hour limit. Our analyses compare trends in resident physician-reported medical errors between the two cohorts to evaluate the impact of this policy change.

"Results 14 796 residents provided data describing 78 101 months of direct patient care. After adjustment for potential confounders, the work-hour policy was associated with a 32% reduced risk of resident physician-reported significant medical errors (rate ratio (RR) 0.68; 95% CI 0.64 to 0.72), a 34% reduced risk of reported preventable adverse events (RR 0.66; 95% CI 0.59 to 0.74) and a 63% reduced risk of reported medical errors resulting in patient death (RR 0.37; 95% CI 0.28 to 0.49).

"Conclusions These findings have broad relevance for those who work in and receive care from academic hospitals in the USA. The decision to lift this work hour policy in 2017 may expose patients to preventable harm."

"From 2003 to 2011, the Accreditation Council for Graduate Medical Education (ACGME) limited residents in their first postgraduate year to a maximum of 30 consecutive work hours, including 6 hours for continuity of care and educational activities (30 hours 2003 ACGME work-hour limit).2 Subsequent evaluations found that shifts of 24 or more hours were associated with increased odds of fatigue-related medical errors and preventable adverse events (PAEs),3 percutaneous injuries4 and motor vehicle crashes.5 A randomised controlled trial found that limiting first-year resident physicians to 16 consecutive work hours significantly improved resident alertness and patient safety.6 7 Altogether, a body of evidence accumulated suggesting that reducing or eliminating shifts longer than 16 hours did not negatively impact resident education and likely improved patient safety and resident quality of life.8 Subsequently, the Institute of Medicine of the National Academies (IOM) reviewed the available evidence and concluded that it was unsafe for any resident physician to provide clinical care for >16 consecutive hours without sleep.9 10 In response, the ACGME issued new work-hour regulations on 1 July 2011, limiting first-year resident physicians to a maximum of 16 consecutive work hours and emphasising a commitment to patient safety and mitigation of fatigue-related risks (16 hours 2011 ACGME work-hour limit).11

"The response within the medical community to the 16 hours 2011 ACGME work-hour limit was mixed.12 Many stakeholders expected the changes to diminish the educational experience.13 The increased frequency of patient handoffs raised concerns, as physician-to-physician handoffs have historically been non-standardised and prone to error.14 In addition, the work-hour limitations were not accompanied by an increased number of residency slots, leading to work compression and a shift in some responsibilities to other clinical providers,15 as well as concerns about resident physician understaffing. Several studies of the 16 hours 2011 ACGME work-hour limit found that it had no impact on hospital-level mortality or mortality following surgical procedures.16–18 In light of these studies and opposition to the work-hour limit from within the medical community, the ACGME lifted the 16-hour limit as of 1 July 2017, again allowing first-year resident physicians to be scheduled for 24 hours of continuous work, plus up to 4 hours for care transitions (28 hours 2017 ACGME work-hour limit)."
