Can we predict death using scoring systems in patients with local peritonitis ? A retrospective study

Area of Science:

• Surgical Gastroenterology
• Critical Care Medicine
• Clinical Prognostication

Background:

• Prognostic scoring systems for local peritonitis (LP) lack comprehensive evaluation.
• Accurate prediction of mortality is crucial for managing LP patients.

Purpose of the Study:

• To assess the predictive accuracy of various scoring systems for mortality in patients with local peritonitis.
• To compare the performance of WSES SSS, MPI, SIRS, and qSOFA in this context.

Main Methods:

• Retrospective analysis of 68 local peritonitis patients (Jan 2017 - Aug 2021).
• Collected clinical and laboratory data for scoring systems at admission or postoperatively.
• Compared prognostic performance using AUROC curves and bivariate correlation analysis.

Main Results:

• Overall mortality rate was 8.8%.
• The Mannheim Peritonitis Index (MPI) demonstrated the best prognostic performance (AUROC=0.805).
• An MPI >25 predicted adverse outcomes with 66.7% sensitivity and 80.6% specificity.

Conclusions:

• The Mannheim Peritonitis Index (MPI) is a reliable tool for prognosticating mortality in local peritonitis patients.
• WSES SSS, qSOFA, and SIRS showed limited ability to predict mortality in this cohort.
