Medical News Today -- Rookie doctors would get shorter shifts and more supervision if new guidelines proposed by the body that accredits medical residency programs go into effect, The Wall Street Journal reports. The change responds to concerns about mistakes by overworked residents. “Many patient advocates and physicians hailed it as a step in the right direction, but it would likely pose logistical and financial challenges for teaching hospitals.” Currently, many medical residents work shifts that can stretch longer than a day with little rest, and studies show overworked residents make more errors. The Accreditation Council for Graduate Medical Education has proposed the change (Wang, 6/24).
