Cutting physicians' work shifts from 80 hours a week has little, if no, effect on patient safety and postgraduate training in the United States, reports Medical News Today. After reviewing U.S. and U.K. studies from 1990 to 2010, researchers found that reducing resident physicians' working hours did not hurt their performance, but nor did it improve the quality of patient care. "Without careful and continued attention to these matters, followed by adjustments to regulations and to practice as required, regulation of working hours is unlikely to have the beneficial effects for patients that regulators and the general public had hoped for," notes Leora Horwitz from Yale University School of Medicine in an accompanying editorial.
