Introduction: In the last 30 years, scoring systems have been developed to determine patients’ illness severity or prognosis. In the present work, the role of the Mannheim Prognostic Index (MPI) to predict the risk of mortality, complications, prolonged hospital-stay, and the need for ICU was determined in all the patients who presented secondary peritonitis, and to validate the test as a useful and an easy tool to apply in the clinical practice of the surgeon and critical care physician. Materials and methods: An observational, retrospective, cross-sectional and analytical study was conducted. Results: The effectiveness of the MPI was compared to another widely used mortality prediction system such as Apache II; 279 patients from the Luis Vernaza were included. The prediction rate was 93.3% and 86.9%, respectively. Conclusions: Although Mannheim presents an excellent response as a predictor of mortality, its assessment is not infallible since other factors remain unconsidered; and these may cause a patient who was assessed as having a low risk of mortality to be deceased.
