Resident fatigue in 2010: where is the beef?

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.

A systematic review of sleep deprivation and technical skill in surgery

BACKGROUND

It is uncertain if sleep deprivation impacts sleepy surgeons' technical skills. Lapses in surgical performance could increase morbidity and mortality. This review concludes if sleep deprivation impacts on technical skill performance in simulated environments.

OBJECTIVE

Primary: 1. To identify if sleep deprivation has an impact on technical skill proficiency in surgeons. Secondary: a. To identify if the level of surgical experience, quality of sleep, or quantity of sleep influences technical skill proficiency in sleep deprived surgeons.

METHODS

The review was conducted according to PRISMA guidelines utilising the databases Journals Ovid. Validation followed with two independent reviewers utilising an adapted version of BEME.

RESULTS

Thirty-three heterogeneous studies were included. Sleep deprivation likely negatively impacts technical performance between 11.9 and 32% decrement in performance. No strong evidence exists with regards to influence of experience, sleep type, or sleep length on technical proficiency.

CONCLUSION

Sleepy surgeons' technical skills are, on balance, between 11.9 and 32% negatively impacted in a standardised simulated environment. This is likely to have clinical implications for patient safety.

How tired is too tired? A case report

We report a case involving a 32-year-old male presenting with acute delirium after completing the daily duties of his job. Though previously well, social history was positive for surgical residency. Symptom resolution was achieved with conservative treatment. We feel that this patient's clinical course represents an emerging disease entity known as "fatigue," which may have important implications for surgical training and practice.
