The POSSUM scoring system is not validated for French colorectal surgery. P-POSSUM and the simpler AFC-index show good predictive value for postoperative mortality.

Area of Science:

  • Colorectal Surgery
  • Surgical Audit
  • Predictive Modeling

Background:

  • Surgical audit relies on scoring systems like POSSUM and P-POSSUM.
  • International validation of these scores is inconsistent.
  • Assessing predictive accuracy in diverse healthcare settings is crucial.

Purpose of the Study:

  • To evaluate the predictive performance of POSSUM and P-POSSUM for colorectal surgery outcomes in France.
  • To compare these established scores with a newly developed French index (AFC-index).
  • To determine the most reliable tool for surgical audit in this specific population.

Main Methods:

  • Prospective multicenter study of 1426 patients undergoing colorectal surgery.
  • Inclusion of elective and emergency cases for malignant or diverticular diseases.

  • Analysis of postoperative in-hospital mortality using POSSUM, P-POSSUM, and the AFC-index.
  • Receiver operating characteristic (ROC) curve analysis for predictive value assessment.

    • Main Results:

    • Overall in-hospital mortality was 3.4%.
    • POSSUM demonstrated poor predictive value, overestimating mortality.
    • P-POSSUM showed good predictive value, though it overestimated deaths in elective cases.
    • The AFC-index, based on four clinical factors, exhibited good predictive value, comparable to P-POSSUM.

    Conclusions:

    • POSSUM is not validated for French colorectal surgery.
    • P-POSSUM and the AFC-index are valuable tools for predicting postoperative mortality.
    • The AFC-index offers a simpler, clinically based alternative to P-POSSUM for surgical audit in France.
