Why the study?
Does the P-POSSUM scoring system accurately predict in-hospital mortality in patients undergoing major digestive surgery?
Does the P-POSSUM scoring system accurately predict in-hospital mortality in patients undergoing major digestive surgery?
The P-POSSUM score is useful for comparing mortality between populations in major digestive surgery but has poor calibration for predicting individual patient outcomes.
No takes yet. Share an insight, caveat, or question.
P-POSSUM overestimation in low-risk patients precludes individual prediction; supports population comparisons but requires recalibration and validation.
Merad et al. (2012) studied this question.
