title: Anterior abdominal stab injury: a comparison of self-inflicted and intentional third-party stabbings.
abstract: BACKGROUND
  There is minimal literature comparing self-inflicted (SI) with non-self-inflicted (NSI) anterior abdominal stab wounds (AASW).
  
  
  METHODS
  Adult patients treated at a level 1 trauma center from 2006 through 2011 with an AASW were reviewed.
  
  
  RESULTS
  There were 215 patients with an AASW; 20% were SI. NSI patients had more nonabdominal injuries (47% vs 16%, P < .01) and disposition directly to the operating room (45% vs 26%, P = .02). Intra-abdominal injury rates were similar. One hundred twenty-eight patients had isolated AASWs; 28% were SI. SI patients had higher admission rates (86% vs 63%, P = .01). One hundred three patients had isolated stable/asymptomatic AASWs; 31% were SI. SI patients had more admissions (84% vs 52%, P < .01), had higher intensive care unit admission rates (23% vs 5%, P = .01), longer LOS (3.2 vs 1.4, P < .01), and higher hospital charges ($18,000 vs $11,000, P < .01). The rates of intra-abdominal injury were again similar.
  
  
  CONCLUSIONS
  Controlling for extra-abdominal injuries, SI AASW patients have similar rates of intra-abdominal injury but use more resources.
