Abstract

Background and AimsEndoscopic retrograde cholangiopancreatography (ERCP) is an invasive procedure that has evolved from being primarily diagnostic to predominantly therapeutic, leading to an increased potential for ERCP-related adverse events. Frailty is an independent predictor of adverse outcomes, and its impact on ERCP-related outcomes requires investigation. This study evaluated the impact of frailty on ERCP-related adverse events. MethodsThe National Inpatient Sample from 2016 to 2019 was used to identify adult patients who underwent ERCP. Frailty was defined using the Frailty Risk Score. Outcomes were categorized into procedure-related adverse events, sedation-related adverse events, and hospitalization outcomes. Multivariate linear or logistic regression was used as appropriate. Stata, version 14.2, was used to perform analyses considering a 2-sided P < 0.05 to be statistically significant. ResultsAmong a total of 693,730 ERCPs performed, 870,30 (12.54%) were frail. Frail patients had higher odds of procedure-related adverse events, including hemorrhage (9.1/1000 vs 4.9/1000) and duodenal perforation, but not post-ERCP pancreatitis, bile duct perforation, cholecystitis, and cholangitis. Frailty imparted a higher risk of sedation-related respiratory failure, aspiration pneumonia, and the requirement of intubation and mechanical ventilation. Inpatient mortality was higher among frail patients (4.54% vs 1.03%), and they had prolonged hospital stays and higher hospitalization costs. ConclusionFrailty is associated with worse outcomes in patients undergoing ERCP, with higher risks of hemorrhage and sedation-related adverse events, in addition to increased resource utilization. Therefore, the findings of this study suggest strict adherence to guidelines governing anticoagulant management during the peri-endoscopic period, and sedative administration should be carefully monitored. Preprocedural optimization measures and diligent monitoring can minimize resource utilization and decrease periprocedural morbidity.
