title: Evaluation of antimicrobial therapy management of 120 consecutive patients with secondary peritonitis.
abstract: OBJECTIVE
  To evaluate antimicrobial therapy management of secondary peritonitis in a University Hospital.
  
  
  METHODS
  All patients admitted to the intensive care unit of the University Hospital of Nîmes from 1 January 1997 to 31 July 1999 with a diagnosis of secondary peritonitis were retrospectively included. Patients' medical records were collected from the data recordings of the Department of Critical Care and Emergency and the Departments of Surgery. Acute Physiology and Chronic Health Evaluation II (APACHE II) was calculated for each patient at the time of admission. Antimicrobial treatment management before and after the diagnosis of peritonitis was studied.
  
  
  RESULTS
  One hundred and twenty patients were included. Results concerning mortality, aetiology of peritonitis and microbiological data were in accordance with previous studies. APACHE II score (P = 0.005), age (P = 0.002), presence of Enterococcus in the peri-operative samples (P = 0.02) and period between diagnosis and surgery (P = 0.04) were predictive of death within 30 days after diagnosis of peritonitis. No significant difference was shown in the mortality rate in patients whose post-operative antibiotic treatment was changed following results of intra-operative peritoneal cultures versus patients having inappropriate treatment (P = 0.96). The same observations were noted for anti-enterococcal treatment.
  
  
  CONCLUSIONS
  This study emphasizes the importance of prompt surgical treatment and shows the modest impact of adapting antibiotic treatment. The morbidity and mortality associated with the presence of Enterococcus, which was not influenced by antibiotic treatment, would seem to suggest the pro-inflammatory role of Enterococcus. However, prospective randomized studies are needed to evaluate the real contribution of enterococcal antibiotic coverage in this context.
