Close outpatient follow-up associated with reduced readmission rates in patients with inflammatory bowel disease.

ABSTRACT

Background: Few studies have shown the effects of prompt outpatient follow-up in relation to reducing readmission rates in patients hospitalized with inflammatory bowel disease (IBD). Our study evaluated whether postdischarge follow-up was associated with fewer IBD-related readmissions. Methods: This single-center retrospective study included 477 patients with Crohn's disease (CD) or ulcerative colitis (UC) who were readmitted to our tertiary care hospital from January 1, 2016, to June 1, 2022. Rehospitalization admissions were defined as admissions that occurred within 90 days after discharge date. We used a chi-square or Fisher's exact test to test for bivariate comparisons to determine if there was an association in patients readmitted for IBD and primary care or gastroenterology follow-up at 1, 2, 3, and 4 weeks versus no follow-up. Results: In UC patients, there were 118 admissions from 2016 to 2022; 36/118 (31%) and 41/118 (34.7%) of the patients were readmitted at 30 days and 90 days, respectively. In the CD group, there were 101 (36.73%) readmissions among 277 patients, with 174 nonreadmissions (63.27%). Conclusions: Gastroenterology follow-up within 1 month was associated with reduced rates of admission in both groups (P < 0.05). This study highlights the importance of close gastroenterology follow-up for IBD-related hospitalizations.
