title: Evaluation of Mannheim peritonitis index and multiple organ failure score in patients with peritonitis.
abstract: BACKGROUND
  Early classification of severity of peritonitis by scoring systems, including the Mannheim peritonitis index (MPI) and the multiple organ failure (MOF) score, modulates surgical and medical management.
  
  
  OBJECTIVE
  To predict outcome of patients with peritonitis using the MPI and MOF scoring systems.
  
  
  METHODS
  Prospective evaluation of the MPI and MOF score was performed in 80 consecutive patients with peritonitis who underwent uniform surgical treatment. Risk ratios were calculated for the MPI and other patient characteristics. Risk ratio was not calculable for the MOF score.
  
  
  RESULTS
  Overall in-hospital mortality rate was 17.5%, including 80% of patients with MPI>29. In non-survivors the mean score was 4.8 (SD 1.46) and 33.07 (4.81) for the MOF score and MPI, respectively. Survivors had mean MOF score of 0.28 (0.20) and mean MPI of 19.39 (6.68).
  
  
  CONCLUSIONS
  The MPI and MOF score provide simple and objective means to predict the outcome of patients with peritonitis.
