Abstract

Background Sleep loss in attending physicians has an unclear effect on patient outcomes. In this study, we examined the effect of medical care provided by physicians after midnight on the outcomes of their scheduled elective procedures performed during the day. Methods We conducted a population-based, retrospective, matched-cohort study in Ontario, Canada. Patients undergoing 1 of 12 elective daytime procedures performed by a physician who had treated patients from midnight to 7 a.m. were matched in a 1:1 ratio to patients undergoing the same procedure by the same physician on a day when the physician had not treated patients after midnight. Outcomes included death, readmission, complications, length of stay, and procedure duration. We used generalized estimating equations to compare outcomes between patient groups. Results We included 38,978 patients, treated by 1448 physicians, in the study, of whom 40.6% were treated at an academic center. We found no significant difference in the primary outcome (death, readmission, or complication) between patients who underwent a daytime procedure performed by a physician who had provided patient care after midnight and those who underwent a procedure performed by a physician who had not treated patients after midnight (22.2% and 22.4%, respectively; P=0.66; adjusted odds ratio, 0.99; 95% confidence interval, 0.95 to 1.03). We also found no significant difference in outcomes after stratification for academic versus nonacademic center, physician's age, or type of procedure. Secondary analyses revealed no significant difference between patient groups in length of stay or procedure duration. Conclusions Overall, the risks of adverse outcomes of elective daytime procedures were similar whether or not the physician had provided medical services the previous night.

Attention Score in Context

This research output has an Altmetric Attention Score of 282. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 May 2019.
All research outputs
#44,400
of 13,762,857 outputs
Outputs from New England Journal of Medicine
#1,428
of 25,746 outputs
Outputs of similar age
#940
of 238,788 outputs
Outputs of similar age from New England Journal of Medicine
#31
of 366 outputs
Altmetric has tracked 13,762,857 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 99th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 25,746 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 64.8. This one has done particularly well, scoring higher than 94% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 238,788 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 99% of its contemporaries.
We're also able to compare this research output to 366 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 91% of its contemporaries.
