Effects of Fatigue on Driving Safety: A Comparison of Brake Reaction Times in Night Float and Postcall Physicians in Training

Strategies to Improve Resident Wellness in Plastic Surgery Training

Residency is known to be a challenging time in a surgeon's career. Surgical residents must learn the breadth of their field and develop technical skills while maintaining relationships and well-being outside their training. High burnout rates are well documented among all medical specialties, particularly during residency. Proven strategies in medical education that help decrease burnout and improve resident well-being, while maintaining quality patient care, have been reported in the medical education literature. However, little has been published specific to plastic surgery training programs. We discuss strategies that can be implemented into the curricula and workflow at plastic surgery residency programs to maximize resident well-being. We advocate for a multifaceted approach that includes a night float system, day call, integrating advanced practice providers to offload noneducational resident tasks, and establishing a wellness program. It is our hope that these strategies may serve as a guide for plastic surgery residency programs to promote general wellness and prevent burnout among trainees.

Extended-Duration Work Shifts in Surgical Specialties: A Systematic Review

INTRODUCTION

There has been widespread international implementation of duration-hour restrictions to prevent surgical resident burnout and promote patient safety and wellbeing of doctors. A variety of Extended-Duration Work Shifts (EDWS) have been implemented, with a variety of studies examining the effect of shift systems on both surgical performance and the stress response unestablished in the literature.

METHODS

This was a systematic review evaluating the impact of extended working hours on surgical performance, cognitive impairment, and physiological stress responses. The review used PubMed, Ovid Medline, Embase, and Google Scholar search engines between September and October 2021 in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Filters including studies carried out after 2002 and published in the English language were applied.

RESULTS

In total, 30 studies were included for analysis. General surgery was the most commonly studied rotation, with Neurosurgical, Orthopedic, and ear, nose and throat specialties also included. The majority of studies found no difference or a significant improvement in post-EDWS on simulated performance. EDWS appeared to have the greatest impact on physiological stress markers in junior surgical trainees.

CONCLUSIONS

Experience appears to confer a protective element in the postcall period, with preservation of skill demonstrated. More experienced clinicians yielded lower levels of physiological markers of stress, although variability in hierarchical workload should be considered. Heterogeneity of findings across physiological, cognitive, and psychomotor assessments highlights the need for robust research on the optimum shift pattern prevents worker burnout and promotes patient safety. Future research to evaluate correlation between stress, on-call workload, and performance in the postcall period is warranted.

Systematic Review of the Impact of Physician Work Schedules on Patient Safety with Meta-Analyses of Mortality Risk

Resident physician work hour limits continue to be controversial. Numerous trials have come to conflicting conclusions about the impact on patient safety of eliminating extended duration work shifts. We conducted meta-analyses to evaluate the impact of work hour policies and work schedules on patient safety. After identifying 8,362 potentially relevant studies and reviewing 688 full-text articles, 132 studies were retained and graded on quality of evidence. Of these, 68 studies provided enough information for consideration in meta-analyses. We found that patient safety improved following implementation of the Accreditation Council for Graduate Medical Education's 2003 and 2011 resident physicians work hour guidelines. Limiting all resident physicians to 80-hour work weeks and 28-hour shifts in 2003 was associated with an 11% reduction in mortality (p < 0.001). Limited shift durations and shorter work weeks were also associated with improved patient safety in clinical trials and observational studies not specifically tied to policy changes. Given the preponderance of evidence showing that patient and physician safety is negatively affected by long work hours, efforts to improve physician schedules should be prioritized. Policies that enable extended-duration shifts and long work weeks should be reexamined. Further research should expand beyond resident physicians to additional study populations, including attending physicians and other health care workers.

Driving Safety Among Surgical Residents in the Era of Duty Hour Restrictions

OBJECTIVE

Fatigued driving is a known contributor to adverse motor vehicle events (AMVEs), defined as crashes and near misses. Surgical trainees work long and irregular hours; the safety of work-related driving since the introduction of work hour regulations has not yet been studied in this population. We aimed to assess the impact of fatigue on driving safety and explore perceptions of a funded rideshare program.

DESIGN

An electronic survey was delivered and inquired in retrospective fashion about fatigue and sleepiness while driving, occurrences of AMVEs, and projected use of a funded rideshare program as a potential solution to unsafe driving. Chi-square testing determined categorical differences between response choices.

SETTING

Yale University School of Medicine, Department of Surgery, New Haven, CT-a general surgery program with 4 urban clinical sites positioned along a roughly twenty mile stretch of interstate highway in Southeastern Connecticut.

PARTICIPANTS

General Surgery residents at the Yale University School of Medicine.

RESULTS

Of 58 respondents (81% response rate), 97% reported that fatigue compromised their safety while driving to or from work. Eighty-three percent reported falling nearly or completely asleep, and 22% reported AMVEs during work-related driving. Junior residents were more likely than Seniors to drive fatigued on a daily-to-weekly basis (69% vs 47%, p = 0.02) and twice as likely to fall asleep on a weekly-to-monthly basis (67% vs 33%, p = 0.02). Despite this, only 7% of residents had ever hired a ride service when fatigued, though 88%, would use a free rideshare service if provided.

CONCLUSIONS

Work-related fatigue impairs the driving safety of nearly all residents, contributing to frequent AMVEs. Currently, few residents hire rideshare services. Eliminating the cost barrier by funding a rideshare and encouraging its routine use may protect surgical trainees and other drivers.

What's it Worth?: The Costs and Benefits of an Initiative to Decrease Post-Call Fatigued Driving Among Surgery Residents

BACKGROUND

In 2017 the ACGME enacted new regulations requiring sponsoring institutions to ensure "safe transportation options for residents who may be too fatigued to safely return home." We investigate here the impact of a pilot "Safe Ride" program designed to mitigate the risks of fatigued driving.

METHODS

During a 2-month pilot period at a single university-affiliated general surgery residency with four urban clinical sites, all residents (n = 72) were encouraged to hire a rideshare (e.g., Uber, Lyft) to and from 24-h clinical shifts if they felt too fatigued to drive safely. The cost of the rideshare was fully reimbursed to the resident. The impact of this intervention was evaluated using utilization data and a post-intervention resident survey.

RESULTS

A total of 16.6% of trainees utilized a rideshare at least one time. Sixty-three post-call rides were taken, predominantly by junior residents (92.4%) and for commutes greater than 15 miles (91%). The cost for the 60-day pilot was $3030. Comparing pre-intervention to post-intervention data, there was a significant improvement in the reported frequency of falling asleep or nearly asleep while driving (P < 0.001). Trainees nearly unanimously (98%) supported efforts to make the program permanent.

DISCUSSION

Driving while fatigued is common among surgical residents, with increased risk among junior residents, during longer commutes and following longer shifts. A reimbursed rideshare program effectively targets these risk factors and was associated with a significant decrease in rates of self-reported fatigued driving. Future efforts should focus on strategies to promote use of reimbursed rideshare programs while remaining cost efficient.

Insufficient sleep and fitness to drive in shift workers: A systematic literature review

BACKGROUND

Insufficient sleep, <6.5 h per night, majorly affects shift workers, placing them at higher risk for motor vehicle crash related injury or fatality. While systematic reviews (SLRs) examine the effects of insufficient sleep and driving, to date, no SLR focuses on driver fitness or performance in shift workers.

OBJECTIVES

Determine the class of evidence (Class I-highest to Class IV-lowest), and level of confidence (Level A-high, to Level U-insufficient) in the determinants of driver fitness and performance in shift workers. Next, consider evidence-based recommendations for clinical practice, research, and policy.

METHODS

A protocol was registered on PROSPERO (#CRD42018052905) using an established SLR methodology: a comprehensive electronic database search, study selection, data extraction, critical appraisal, analysis, and interpretation using published guidelines.

RESULTS

Searches identified 1226 unique records with 11(2 on-road, 9 simulator) meeting final inclusion criteria. Class III to IV evidence identified that exposure to overnight shift work possibly predicts (Level C confidence) drivers at risk for adverse on-road outcomes and likely predicts (Level B) drivers at risk for adverse driving simulator outcomes. Higher ratings of subjective sleepiness and extended time driving possibly predict (Level C) drivers at risk for adverse driving simulator outcomes.

CONCLUSIONS

This study demonstrates a low to moderate level of confidence in the determinants of driving in shift workers. A critical need exists for gold-standard on-road assessments integrating complex driving environments representative of real-world demands, targeting tactical and strategic outcomes in a broad spectrum of shift workers.

Shorter Versus Longer Shift Durations to Mitigate Fatigue and Fatigue-Related Risks in Emergency Medical Services Personnel and Related Shift Workers: A Systematic Review

BACKGROUND

This study comprehensively reviewed the literature on the impact of shorter versus longer shifts on critical and important outcomes for Emergency Medical Services (EMS) personnel and related shift worker groups.

METHODS

Six databases (e.g., PubMed/MEDLINE) were searched, including one website. This search was guided by a research question developed by an expert panel a priori and registered with the PROSPERO database of systematic reviews (2016:CRD42016040099). The critical outcomes of interest were patient safety and personnel safety. The important outcomes of interest were personnel performance, acute fatigue, sleep and sleep quality, retention/turnover, long-term health, burnout/stress, and cost to system. Screeners worked independently and full-text articles were assessed for relevance. Data abstracted from the retained literature were categorized as favorable, unfavorable, mixed/inconclusive, or no impact toward the shorter shift duration. This research characterized the evidence as very low, low, moderate, or high quality according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology.

RESULTS

The searched yielded n = 21,674 records. Of the 480 full-text articles reviewed, 100 reported comparisons of outcomes of interest by shift duration. We identified 24 different shift duration comparisons, most commonly 8 hours versus 12 hours. No one study reported findings for all 9 outcomes. Two studies reported findings linked to both critical outcomes of patient and personnel safety, 34 reported findings for one of two critical outcomes, and 64 did not report findings for critical outcomes. Fifteen studies were grouped to compare shifts <24 hours versus shifts ≥24 hours. None of the findings for the critical outcomes of patient and personnel safety were categorized as unfavorable toward shorter duration shifts (<24 hours). Nine studies were favorable toward shifts <24 hours for at least one of the 7 important outcomes, while findings from one study were categorized as unfavorable. Evidence quality was low or very low.

CONCLUSIONS

The quality of existing evidence on the impact of shift duration on fatigue and fatigue-related risks is low or very low. Despite these limitations, this systematic review suggests that for outcomes considered critical or important to EMS personnel, shifts <24 hours in duration are more favorable than shifts ≥24 hours.
