SP 9.11 Correlation of Observed and Predicted 30-Day Mortality Using NELA, ACS-NSQIP and SORT in Romanian Octogenarian and Nonagenarian Emergency Laparotomy Patients: A Multicentre Retrospective Cohort Study

Risk prediction models correlate poorly with 30-dm and demonstrate substantial calibration error in elderly EL patients and demonstrate substantial calibration error in elderly EL patients in Romanian patients aged ≥80 years.

TPW 4.01 Correlation Between Observed Mortality and NELA-Predicted 30-Day Mortality Following the Five Most Common Emergency Laparotomy Procedures in Romania: A Retrospective Multicentre Observational Cohort Study

Emergency laparotomy (EL) comprises heterogeneous high-risk procedures with substantial postoperative mortality, reaching 8–18% at 30 days. Although overall 30-day mortality (30-dm) is well documented, procedure-specific outcomes remain limited. Defining intervention-level mortality may improve risk stratificatio...

TPT 3.01 Correlation Between Observed Mortality and SORT-Predicted 30-Day Mortality Following the Five Most Common Emergency Laparotomy Procedures in Romania: A Retrospective Multicentre Observational Cohort Study

Limited reliability, weak correlation, and persistent misprediction of 30-day mortality across the five most common emergency laparotomy procedures in Romania demonstrated limited reliability, weak correlation, and persistent misprediction.
