Thirty-day readmission rates, reasons, and costs for gastrointestinal angiodysplasia-related bleeding in the USA

Eur J Gastroenterol Hepatol. 2022 Jan 1;34(1):11-17. doi: 10.1097/MEG.0000000000002027.

Abstract

Background: Patients with gastrointestinal angiodysplasia (GIA)-related bleeding are at high risk for readmissions, resulting in significant morbidity and an economic burden on the healthcare system.

Aim: The aim of the study was to determine the 30-day readmission rate with reasons, predictors, and costs associated with GIA-related bleeding in the USA.

Methods: We queried the National Readmission Database to identify patients hospitalized with GIA-related bleeding in the year 2016 using the International Classification of Diseases, Tenth Revision (ICD-10) codes. Primary outcomes included the 30-day readmission rate, and secondary outcomes were in-hospital mortality and resource utilization for index and re-hospitalizations. We also performed univariate and multivariate cox regression analysis to identify predictors of readmissions.

Results: A total of 25 079 index hospitalizations for GIA-related bleeding were identified in 2016. Out of these, 5047 (20.34%) patients got readmitted within the next 30 days. The most common diagnosis associated with readmissions were related to recurrent gastrointestinal bleeding. Readmissions compared to index hospitalization has significantly higher length of stay (5.38 vs. 5.11 days, P = 0.03), but mean hospitalization charges ($52 114 vs. $49 691, P = 0.11) and mean total hospitalization costs ($12 870 vs. $12 405, P = 0.16) were similar. Patients with multiple co-morbidities, length of stay >5 days, and end-stage renal disease were found to be independent predictors for 30-day readmissions.

Conclusion: Our study shows that one in five patients hospitalized with GIA-related bleeding was readmitted within 30 days of index hospitalization, placing a heavy economic burden on the healthcare system. Further research identifying strategies to reduce readmissions in these patients is needed.
