Key result
POSSUM, P-POSSUM, and the Surgical Risk Scale showed excellent discrimination for predicting mortality in general surgery patients (AUCs 0.97, 0.966, and 0.91, respectively; all p<0.0001).
Why the study?
How do POSSUM and P-POSSUM scoring systems compare to the Surgical Risk Scale (SRS) in predicting 30-day morbidity and mortality in patients undergoing general surgery?
Cohort (n=721)
How do POSSUM and P-POSSUM scoring systems compare to the Surgical Risk Scale (SRS) in predicting 30-day morbidity and mortality in patients undergoing general surgery?
Effect estimate: AUC 0.97 (95% CI 0.948-0.992)
p-value: p=< 0.0001
P-POSSUM and SRS are effective and accurate tools for predicting mortality in patients undergoing general surgery, whereas POSSUM significantly overestimates both morbidity and mortality.

González-Martínez et al. (2016) conducted a cohort in General surgery (n=721). POSSUM and P-POSSUM scoring systems vs. Surgical Risk Scale (SRS) was evaluated on Mortality prediction (discrimination ability) (AUC 0.97, 95% CI 0.948-0.992, p=< 0.0001). POSSUM, P-POSSUM, and the Surgical Risk Scale showed excellent discrimination for predicting mortality in general surgery patients (AUCs 0.97, 0.966, and 0.91, respectively; all p<0.0001).
