Minnesota has the nation's best-performing healthcare system, according to a Commonwealth Fund ranking released this week, and Massachusetts, Vermont, and New Hampshire are tied for second. Mississippi ranks last, just as it did on the previous ranking in 2009. Louisiana, Oklahoma, and Arkansas round out the bottom of the list. For the ranking, the Commonwealth Fund relied on 42 different metrics that gauged everything from insurance coverage to avoidable hospital stays to vaccination rates, at the systemic level; and from obesity rates to how many adults have lost six or more teeth, at the individual level.
