In an article published in the Journal of the Americal Medical Association, Dr. J. Todd Arnedt, et al, concluded that following a heavy call, medical residents performed a series of driving-related tasks approximately as well as after completing a light call and boozing it up to a BAC of .04-05%:
Participants achieved the target blood alcohol concentration. Compared with light call, heavy call reaction times were 7% slower; commission errors were 40% higher; and lane variability and speed variability on the driving simulator were 27% and 71% greater, respectively. Speed variability was 29% greater in heavy call with placebo than light call with alcohol, and reaction time, lapses, omission errors, and off-roads were not different…
Post-call performance impairment during a heavy call rotation is comparable with impairment associated with a 0.04 to 0.05 g% blood alcohol concentration during a light call rotation, as measured by sustained attention, vigilance, and simulated driving tasks. Residents’ ability to judge this impairment may be limited and task-specific.
Now what we see is a higher likelihood that sleep-deprived residents will cause highway accidents, resulting in more work for emergency and surgery residents, which could result in more sleep deprived residents…
