If you should have the misfortune of being involved in a serious motor vehicle accident or other incident resulting in personal injuries, chances are very good that you will be taken to the nearest emergency room and possibly be admitted to the hospital.
Here, the chances are also very good that your care will be managed by a medical resident, a young physician who works under the supervision of an older, more experienced, and fully licensed physician.
Interestingly, the number of hours that these medical residents are allowed to work each shift without taking a break were shortened from 30 hours to 16 hours as recently as 2011 by the Accreditation Council for Graduate Medical Education, the organization that oversees these matters. One of the primary reasons for the shorter shifts was that it would lead to fewer medical mistakes attributable to fatigue and/or stress.
