The two faces of intentional self-inflicted injury: High in-hospital mortality, low postdischarge mortality, but high readmission rates.

Background: Intentional self-inflicted injuries present unique challenges in treatment and prevention. We hypothesized intentional self-inflicted injuries would have higher in-hospital and postdischarge mortality than nonintentional self-inflicted injuries trauma.

Methods: Adult patients evaluated 2008 to 2012 were identified in our trauma registry and matched with mortality data from the National Death Index.
