Why the study?
P-POSSUM is frequently used to determine mortality in emergency laparotomy, while NELA offers a novel validated score, prompting a comparison of their performance in predicting 30-day and 90-day mortality.
Does the NELA score perform better than the P-POSSUM score in predicting 30-day and 90-day mortality in patients undergoing emergency laparotomy?

Moderate AUCs for NELA and P-POSSUM indicate limited accuracy; leaves open need for refined risk models in emergency laparotomy.
Does the NELA score perform better than the P-POSSUM score in predicting 30-day and 90-day mortality in patients undergoing emergency laparotomy?
Both NELA and P-POSSUM scores underestimated mortality risk, with discernible differences in predictive performance for 30-day and 90-day mortality in patients undergoing emergency laparotomy.
