O33: PROSPECTIVE RISK ASSESSMENT ALONE DOES NOT IMPROVE 30-DAY MORTALITY IN EMERGENCY LAPAROTOMY PATIENTS

Abstract Introduction Emergency laparotomy still carries a high mortality risk. According to the latest National Laparotomy Audit (NELA) report, half of patients without pre-operative risk scoring had higher observed than predicted mortality. Data from Perth, Australia also suggests that improves The aim this study was determine if prospective assessment has an independent favourable effect on outcomes.

Median preoperative P-POSSUM score 6.9%, – 5.2%. total 27/133 (20.3%) scored days; 45/719 (6.3%) Neither these rates very different predicted. Conclusion 30-day Hunter New England region, Australia, compares favourably with figures reported by NELA. However, contrary other publications, alone did not have any beneficial our cohort Take-home message Patients undergoing surgery require improve just fact assigning preoperatively does help
