Insights
Pediatric surgery fellows experience significantly less sleep on call nights due to work communications, impacting their rest. This study highlights the need for interventions to improve sleep for these essential medical professionals.
Area of Science:
- Medical Education
- Sleep Medicine
- Surgical Training
Background:
- Pediatric surgery fellows are crucial for academic children's hospitals, providing essential overnight clinical coverage.
- Limited objective data exists on the sleep patterns and communication burdens of fellows during overnight home call.
Purpose of the Study:
- To objectively assess the sleep patterns and work-related communications of a pediatric surgery fellow during overnight home call.
- To identify the impact of call duties on fellow sleep duration and quality.
Main Methods:
- Prospective observational study conducted over 60 call nights and 60 non-call nights.
- Involved a senior pediatric surgery fellow at an academic children's hospital.
- Data collected from September 2022 to February 2023.
Main Results:
- Fellows averaged 5.8 hours of sleep, with significantly less sleep on call nights (5.4 hours) versus non-call nights (6.3 hours).
- An average of four work-related communications occurred per 12-hour night shift, primarily concerning new consults.
- Approximately half of these communications interrupted sleep, with an average of 23.8 minutes of sleep disturbance per shift.
Conclusions:
- Overall sleep duration for pediatric surgery fellows falls below recommended levels.
- Overnight call duties significantly disrupt sleep patterns and are compounded by work-related communications.
- Further research and interventions are necessary to address sleep disturbances and improve fellow well-being.
Objective:
A pediatric surgery fellow is often regarded as a cornerstone of an academic children's hospital due to the need for their clinical services with overnight coverage being an important aspect of the care provided. There is little known about the objective sleep patterns and work-related communications of a pediatric surgery fellow during overnight home call. The aim of this study is to better understand the sleep patterns and interruptions of an on-call pediatric surgery fellow.
Design:
A prospective observational study of 60 call nights and 60 non-call nights of a pediatric surgery senior fellow was performed from September 2022 to February 2023.
Setting:
An academic Children's Hospital.
Participant:
An ACGME-accredited clinical pediatric surgery fellow.
Results:
On average, the pediatric surgery fellow spent 6.9 and 5.8 total hours in bed and asleep each night, respectively. The total sleep time was less for call nights compared to non-call nights (5.4 versus 6.3 h, p < 0.0001). The mean number of work-related communications per 12-hour night shift was four. The majority of communications were regarding new consults (63.8 %). The pediatric surgery fellow spent an average of 5.9 min per communication and approximately 23.8 min total during each 12-hour night shift. Approximately half of these communications occurred during sleep hours.
Conclusions:
This study reveals overall sleep duration was below recommended levels. There were significant alterations in sleep patterns during call nights. Work-related communications further compounded sleep disturbances. Further research and interventions in this area are warranted.
