Question special

While strong cases can be made for 24- and 28-hour shifts with resident wellbeing in mind (e.g. shorter shifts on other days, improved continuity for learning, possibly improved sleep habits), safety concerns do remain. Motor vehicle accidents are perhaps the quintessential example.

Anecdotally, I personally know very few residents who have not experienced some form of motor vehicle accident during their residency. This doesn't necessarily implicate the duty hours, but it is certainly a prevalent enough event to warrant investigation.

15.6% of learners in the flexible group reported that fatigue "almost always or often" affected their safety, compared with 8.7% in the standard group. Is there any other data regarding safety outcomes or incidents for residents? How strongly should we dig for this information.
