Does P-POSSUM or POSSUM accurately predict mortality and morbidity in patients undergoing emergency laparotomy?
P-POSSUM is a more accurate predictor of mortality than POSSUM in patients undergoing emergency laparotomy, though both scores overpredict mortality in low-risk groups.
No takes yet. Share an insight, caveat, or question.
