Summary

This review identifies surgical risk scoring systems for general surgeons. The Physiological and Operative Severity Score for enUmeration of Mortality and morbidity (POSSUM) is recommended for assessing patient risk and outcomes.

Area of Science:

  • Surgical Outcomes Research
  • Medical Informatics
  • Health Services Research

Background:

  • Numerous risk scoring systems have been developed for surgical patients.
  • This review focuses on systems relevant to general surgical practice.

Purpose of the Study:

  • To review existing surgical risk scoring systems.
  • To identify the most appropriate system for general surgical practice.

Main Methods:

  • A comprehensive literature search of Medline was conducted from 1966 to 1997.
  • Keywords included 'severity of illness', 'morbidity', 'mortality', and 'postoperative complications'.
  • Specific scoring systems and their references were also reviewed.

Main Results:

  • Several risk scoring systems are available for surgical patients.
  • The Physiological and Operative Severity Score for enUmeration of Mortality and morbidity (POSSUM) was identified as highly relevant.

Conclusions:

  • Accurate risk assessment improves individual prognosis and treatment selection.
  • Risk scores facilitate audit and research by comparing predicted vs. actual patient outcomes.
  • POSSUM is the most suitable scoring system for general surgical practice.
