Background and aims: Pancreaticobiliary diseases are common in the elderly. To this end, frailty represents a state of vulnerability that should be considered when assessing the risks and benefits of therapeutic endoscopic procedures. We aim to determine the rate of readmissions and clinical outcomes using the validated Hospital Frailty Risk Score in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP).
Methods: Using the National Readmissions Database, we identified patients with an admission diagnosis of cholangitis with obstructive stone from 2016 to 2019. Patients were determined to be of low frailty risk with a score of < 5, while patients of medium to high frailty risk had a score of > 5.
Results: During the study period, 5751 patients were identified with acute cholangitis with obstructing stone. Mean age of index admissions was 69.4 years and 51.8% were female. From the total cohort, 5119 (89.2%) patients underwent therapeutic ERCP, 38.0% (n = 1947) of whom were regarded as frail (risk score > 5). Following ERCP, frail patients had a less but statistically insignificant readmission rate compared to non-frail patients (2.76% vs 4.05%, p = 0.450). However, compared to non-frail patients, frail patients experienced higher post-ERCP complications (6.20% vs 14.63%, p < 0.001). Frail patients were more likely to have longer lengths of stay, higher hospital cost, and mortality risk.
Conclusion: ERCP is not a risk factor for readmission among frail patients. However, frail patients are at higher risk for procedure-related complications, healthcare utilization, and mortality.
