This week’s Health Wonk Review kicks off with posts debating the issues of residents’ sleep deprivation and long physician work weeks. It then moves to one of the hot-button health policy  issues of the past week – namely, why the New York Times took on the Dartmouth Atlas and studies of variations in medical practice. Tinker Ready of the blog, Boston Health News, hosts this edition of the Health Wonk Review, a biweekly round-up of health policy blogging.
