title: [Postoperative dehiscence of the abdominal wound and its impact on excess mortality, hospital stay and costs].
abstract: BACKGROUND
  The objectives of this study were to investigate the relationship between several factors and the incidence of postoperative abdominal wall dehiscence (POAD), and to estimate the influence of POAD on in-hospital mortality, excess length of stay and costs.
  
  
  METHODS
  Retrospective observational study of a sample of abdominal surgery patients from a minimal basic data set of 87 Spanish hospitals during 2008-2010.
  
  
  RESULTS
  Among 323,894 admissions for abdominal surgery reviewed there were 2,294 patients with POAD. Elderly patients, male, with non-elective admission, with alcohol, tobacco or drugs abuse, and with more comorbidities had higher incidence. POAD patients had an increase in in-hospital death (mortality excess of 107.5%), excess length of stay (15.6 days) and higher cost (14,327 euros).
  
  
  CONCLUSIONS
  Certain demographic and behavioral variables, and several comorbidities are associated with the incidence of POAD, and this complication shows an increase in in-hospital mortality, the length of hospital stay and costs. Preventive measures might decrease the incidence of POAD and its impact on health and extra-costs.
