Abstract

Background and aim: The literature is lacking on associations of endoscopic retrograde cholangiopancreatography (ERCP) related outcomes in rheumatoid arthritis (RA) patients. The aim of this study is to evaluate the effects of RA on clinical outcomes and hospital resource utilization in patients undergoing ERCP.

Methods: The National Inpatient Sample database was used to identify hospitalized patients who had underwent an ERCP study from 2012 to 2014 using International Classification of Diseases-Ninth Edition (ICD-9) codes. Primary outcomes were mortality, hospital charges, and length of stay. Secondary outcomes were ERCP-related complications. Chi-squared tests for categorical data and independent t-test for continuous data were utilized. Multivariate analysis was performed to assess the primary outcomes.

Results: There was 83 890 ERCP procedures performed, of which 970 patients had RA. In patients with RA, 74.2% were female, and the average age was 65.7 years. RA primary outcomes of mortality rate and hospital cost were lower and statistically significant. There was no statistically significant difference in secondary outcomes except for lower cholecystectomy rates in RA patients.

Conclusion: With a high inflammatory state, it was hypothesized that RA would be associated with worse outcomes after ERCP. Yet, the primary outcomes of mortality and hospital cost were found to be lower than controls, with no difference in secondary outcomes. We posit that immunosuppressants used to treat RA provides a protective effect to overall complications with ERCP.
