PurposeEmergency laparotomy (EL) encompasses procedures of varying complexity and urgency, undertaken in different clinical scenarios, leading to different risks of morbidity and mortality. We hypothesized that the increased mortality and longer postoperative length of stay (LoS) observed in frail patients are related to differences in indication for operation, a higher rate of sepsis, worse intraperitoneal soiling, and more advanced malignancy in this group.MethodsThis retrospective cohort study analysed patients entered into the National Emergency Laparotomy Audit database between January 1, 2018, and June 15, 2021, in Oxford. The primary outcome was 180-day survival analysed using multivariable Cox regression. The secondary outcomes, delay to surgery (DtS) and postoperative LoS, were analysed using logarithmically transformed multivariable linear regression.ResultsOf the 803 patients analysed, 396 (49.3%) were male. The median age was 66, and 337 (42%) were living with at least very mild frailty. Mortality hazard ratios for Clinical Frailty Scale grades 4 (3.93, 95% CI 1.89-8.20), 5 (5.86, 95% CI 2.87-11.97), and 6-7 (14.17, 95% CI 7.33-27.40) were not confounded by indication, sepsis, intraperitoneal soiling, or malignancy status. Frail patients experienced a 1.38-fold longer DtS and a 1.24-fold longer postoperative LoS, even after adjusting for indication, sepsis, intraperitoneal soiling, malignancy status, and DtS.ConclusionOur results indicate that frail patients have a poorer prognosis and longer postoperative LoS, independent of DtS, indication, sepsis, intraperitoneal soiling, and malignancy status. Patient frailty is also associated with longer DtS.© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany.
