Impact of Volume and Type of Overnight Pages on Resident Sleep During Home Call.

Background: Little research exists regarding factors that contribute to resident fatigue during home call.

Objective: We objectively tracked the number and type of pages received, as well as residents' sleep time, during home call. We then examined the relationship between paging volume, resident sleep, and resident fatigue.

Methods: A total of 4 of 4 urology residents (100%) at a single institution wore a FitBit Charge HR device from July 2015 to July 2016 to track sleep. Between January and July 2016, pages received by the on-call resident were counted as either (urology inpatient unit), (after-hours answering service), or . Postcall residents were defined as and excused at noon if they reported they were too tired to safely perform clinical duties.

Results: Residents slept an average of 408 minutes per night while not on call, versus 368 minutes while on call but not fatigued, and 181 minutes while on call and fatigued ( < .05). The most senior resident received fewer pages per night on average than the most junior resident. Each page was associated with 4.71 fewer minutes asleep on average for all residents. Pages in the category were associated with 7.74 fewer minutes asleep per page for all residents, but only the most junior resident had significantly less sleep, 9.02 minutes, per page.

Conclusions: Objective sleep data correlate with subjective assessment of resident fatigue and with volume and type of pages received. Senior residents spent less time awake per page and received fewer pages.
