In severe intra-abdominal infections and peritonitis, the mortality rate may increase to greater than 30-50%. The concurrent development of sepsis, SIRS, and MOF can increase the mortality rate to greater than 70%, and, in these patients, more than 80% of deaths occur with an active infection present.
