A new study in the BMJ says yes. The researchers, led by Dr. Anupam Jena, a professor of health care policy and medicine at Harvard Medical School, and Stanford Health Policy's Jay Bhattacharya, looked at the performance of internal medicine doctors in their first year of unsupervised medical practice after completing their training. 

They compared the outcomes for patients of two groups of physicians: those trained before 2003, when the typical work week was 100 hours; and those trained later under the new rules, which capped weekly hours at a mere 80, with no individual shift exceeding 30 hours.
