BACKGROUND: The National Emergency Laparotomy Audit (NELA) highlights the importance of identifying high-risk patients due to the potential for significant morbidity and mortality. The NELA risk prediction calculator (NRPC) was developed from data in England and Wales and is one of several calculators available. We seek to determine the utility of NRPC in the Australian population and compare it with Portsmouth Physiological and Operative Severity Score for the enumeration of mortality and Morbidity (P-POSSUM) and American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) calculators. METHODS: A retrospective review of all emergency laparotomies undertaken at four Australian centers was performed between January 2016 and December 2017. Data extracted from patient records were used to calculate NRPC, ACS-NSQIP, and P-POSSUM scores for 30-day mortality risk. The sensitivity of NRPC was assessed using the NELA high-risk cohort score of ≥10% and this was compared with the other two calculators. RESULTS: There were 562 (M = 261, mean age = 66 [±17] y) patient charts reviewed in the study period. 59 patients died within 30 d (10.5%). NRPC was able to identify 52 (sensitivity = 88.1%) of these as being within the high-risk group. Using the NELA high-risk cutoff, NRPC identified 52 deaths of 205 (25.4%) high-risk patients, P-POSSUM identified 46 of 245 (18.8%), and ACS-NSQIP identified 46 of 201 (22.9%). Using the McNemar test, no significant difference was noted between NRPC and P-POSSUM (P = 0.07) or NRPC and ACS-NSQIP (P = 0.18). CONCLUSIONS: In the Australian context, the NRPC is a highly sensitive and useful tool for predicting 30-day mortality in high-risk emergency laparotomy patients and is comparable with P-POSSUM and ACS-NSQIP calculators.
