Modified Frailty Index and Brief Geriatric Assessment does not predict prolonged hospitalization in elderly patients undergoing appendectomy due to Acute Appendicitis

Abstract

Epidemiology and the outcomes of acute appendicitis in elderly people are very different from the younger patients. Aim of this study was to investigate the significance of frailty syndrome in the course of acute appendicitis. All patients over 65 years old who underwent laparoscopic appendectomy between 2013 and 2021 in 2nd Department of General Surgery were included in the study. In our assessment Modified Frailty Index and Brief Geriatric Assessment were performed. In the analyzed period 106 appendectomies were performed in patients over 65 years old. Postoperative complications occurred in 13 patients (12.3%). Prolonged hospitalization (over 3 days) was observed in 48 patients (45.3%). Multivariate analysis showed that every ASA class (OR=2.406; 95% CI 1.089-5.316; p=0.030) and postoperative complication (OR=5.692; 95% CI 1.077-30.073; p=0.041) are risk factors for prolonged hospitalization. Our study identified diabetes (OR=5.956; 95% CI 1.391-25.510; p=0.016) as a risk factor for postoperative complications. According to our study Modified Frailty Index and Brief Geriatric Assessment does not correlate with prolonged hospitalization or higher risk for postoperative complication after appendectomy in elderly people.
