The Value of Mannheim Peritonitis Index Combined With ASA Classification in Predicting Postoperative Mortality of Patients With Digestive Tract Perforation.

Key Result

Combined Mannheim Peritonitis Index and ASA Classification predict postoperative mortality in digestive tract perforation patients better than either alone.

Key Points

This research aims to evaluate how well the combined Mannheim Peritonitis Index and ASA Classification predict mortality in patients with digestive tract perforation.
Assessments of MPI score and ASA Classification were performed in patients with digestive tract perforation.
Comparative analysis of predictive performance between combined and individual assessments.
Mortality rates were tracked postoperatively.
The combination of MPI and ASA provided superior predictive performance compared to either method alone.
Patients classified using both MPI and ASA had more accurate risk assessments for mortality.

Structured PICO

Does the combined assessment of MPI score and ASA Classification improve the prediction of postoperative mortality in patients with digestive tract perforation compared to either score alone?

Population

Patients with digestive tract perforation (DTP)

Intervention

Combined assessment of Mannheim Peritonitis Index (MPI) score and ASA Classification

Comparator

Application of MPI score or ASA Classification alone

Outcome

Postoperative mortality risk predictionhard clinical

Combining the Mannheim Peritonitis Index and ASA Classification improves the prediction of postoperative mortality in patients with digestive tract perforation.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

In the prediction of mortality risk in DTP patients, the combined assessment of MPI score and ASA Classification exhibits better predictive performance compared with the application of MPI score or ASA Classification alone.
