In Health Affairs, Scott Lorch and colleagues suggest that the way in which hospitals respond to disruptions caused by the closure of nearby facilities could influence patient outcomes. They look at the example of obstetric services in Philadelphia, where 13 of 19 hospital obstetric units closed between 1997 and 2012. This led to a "severely strained obstetric care system," according to interviews with key informants in hospitals with units still open. The authors conclude that policymakers need to do more to anticipate reductions in supply and monitor patient outcomes.
