Female trainees specializing in surgery, emergency medicine, and anesthesiology were most affected by sleep-related impairment.
Sleep-related impairment was prevalent in a new study’s sample of more than 11,000 attending and trainee physicians. When physicians were not able to get enough sleep, there was an increase in burnout and a decrease in professional fulfillment.1
Excessive, often unpredictable work hours are commonplace in many doctors’ schedules, and sleep-related impairment can become an occupational hazard.2-4 The results of multiple different studies show that inadequate sleep has significant health and cognitive performance consequences.5-8
When a doctor doesn’t get enough sleep, he loses the ability to identify patient emotions, explore the reasons for those emotions, and validate emotions, which hinders interpersonal communication.8-11 Sleep deprivation disrupts cognitive processing and connectivity between amygdala anterior cingulate and media prefrontal cortex, resulting in emotional dysregulation.12-15 Furthermore, a physician’s ability to maintain attention decreased in tandem with sleep loss.16
Most doctors are intuitively aware of the link between sleep-related impairment and burnout among physicians, but few studies have actually evaluated it.17,18This study assessed the association between sleep-related impairment and occupational wellness indicators, including work exhaustion, interpersonal disengagement, overall burnout, and professional fulfillment.
The study used a large sample of physicians in postgraduate training as well as attending physicians at academic-affiliated medical centers to assess the associations of sleep-related impairment and burnout with self-reported data. Additionally, it categorized results by medical specialty and between attending physicians and postgraduate medical trainees in the same specialty.1
The study measured sleep-related impairment by utilizing the Patient-Reported Outcomes Measurement Information System (PROMIS) 8-item scale that assesses tiredness, alertness, sleepiness, and functional deficits related to inadequate sleep. Researchers categorized scores from 8 to 11 as negligible levels of sleep-related impairment, 12 to 15 as low, 16 to 21 as high, and 22 to 40 as very high.
The mean sleep-related impairment scale score in physicians was 16.9. Among trainee physicians, it was 20.7. Variations in sleep-related impairment were seen among different specialties, genders, and training status, with female trainees specializing in surgery, emergency medicine, and anesthesiology most affected.1
Emergency medicine specialists had the highest sleep-related impairment scores among attending physicians, and surgical specialists had the lowest.
When comparing attending surgical specialists scores with the national PROMIS data bank’s median of 16, results showed a lower than average mean of sleep-related impairment.1 In contrast, trainee surgical specialists had the highest sleep-related impairment of the 12 specialty categories of postgraduate training specialties.1
OD weighs in
Optometry Times® asked Editorial Advisory Board member Michael BrownOD, MHS-CL, FAAO, to weigh in on the study’s results. Dr. Brown says the study shows a strong association between sleep deprivation and burnout, but the authors also point out that they did not assess for a cause-and-effect relationship.
“I know the times during my career when I have struggled most with burnout, I didn't sleep long or well, but I felt the insomnia, poor quality, and early morning waking were more a symptom of burnout than the cause,” says Dr. Brown. “Once the causes were addressed, my sleep pattern normalized.”
Dr. Brown says he averages only about 6 hours of sleep each night but doesn’t suffer any ill effects. His doctor isn’t concerned as long as he stays healthy and happy and functions well.
“I hope researchers are looking at why some people need less sleep and some more and also if there is a health benefit to being in bed and relaxed for the “recommended 8 hours” rather than asleep the whole time.”
