EP.FRI.552 Evaluating short term and long term outcome for patients undergoing emergency laparotomy in comparison to NELA mortality risk calculator
Abstract Aim NELA is a project that was introduced in the UK since 2013, aiming to improve quality of care for patients undergoing emergency laparotomy. NELA mortality risk calculator”was launched in 2017, which estimates the risk of death within 30 days of emergency laparotomy. Our aim is to determine the short-term (30-day) and long-term (12 months) outcome in patients undergoing emergency laparotomy surgery and compare this with the estimated scores that were documented in the NELA website. Methods This is retrospective study involving patients who underwent emergency laparotomy surgery in the year of 2019. The primary outcome is to determine short-term (30-day) mortality. Results A total of 135 patients were included. The overall 30-day mortality was 8.8% (12/135). 55.77% (78/135) had NELA mortality score of < 5%. Only 1 out of these (1.28%) died within 30 days. (4/78,5.12%) died in 6 to 12 months period of this group. 9 patients (11.53%) had NELA score > 30%, of which 6 (66.66%) died within 30 days and 1 died within 6 months. 26.96% (48/135) had NELA scores 55 to 30%, 5 of them (10.41%) died within 30 days while 7 (14.58%) died within 6-12 months. Patients with NELA scores more than 5% who survived the operation had higher chance of 30-day complications (25.58%, 11/43), when compared to those with scores less than 5% (11.68%, 9/77). Conclusion NELA mortality score has high accuracy especially if it was >30%. In addition, high NELA scores are associated with increased risk of post operative complications.
