276 Clinical and Demographic Factors Influencing Length of Hospital Stay in Pancreatitis: A Retrospective Study

Aim Evaluate the impact of demographic and clinical factors on the length of hospital stay (LOS) following admission with acute pancreatitis over 12-months. Method For this retrospective cohort study, we used electronic patient records to identify all patients admitted with acute appendicitis in 2022; 162 admissions were identified. Microsoft Excel was used to collect the data and SPSS was used to analyse the data. Results Mean LOS was 8.31 days. The cases were comprised of 85 (52.5%) males and 77 (47.5%) females – sex had no impact on LOS (p=0.690). Average age of the patients was 54.2 years with no correlation to LOS (p = 0.261). Looking at aetiology, gallstones (34.6%), undetermined (31.5%), alcohol (27.2%), hypertriglyceridaemia (3.1%), ERCP (1.9%) steroids (0.6%), trauma (0.6%) and autoimmune (0.6%), we found no impact on LOS (p = 0.915). Increase in LOS is noted with higher Rockwood frailty scores (p = 0.000). 42 patients (25.9%) were made nil by mouth (NBM), resulting in longer LOS (p = 0.002). 8 (4.9%) patients were admitted to ITU and had longer LOS (T = -7.34, p = 0). Only 14 cases (8.64%) had a recorded Glasgow-Imrie Score on admission. Conclusions The significant determinants of LOS in this study were pre-morbid frailty, ITU admission and NBM status. While the Glasgow-Imrie score has been found to identify the severity of pancreatitis, use of this score at our centre was poor. By making this mandatory we hope to identify severe cases, allowing prompt resuscitation and more focused treatment to ultimately reduce LOS.
