Abstract

Background:

The management of inflammatory bowel diseases (IBDs; Crohn's disease, ulcerative colitis) is increasingly complex. Specialized care has been associated with improved ambulatory IBD outcomes.

Aims:

To examine if the implementation of specialized inpatient IBD care modified short-term and long-term clinical outcomes in IBD-related hospitalizations.

Methods:

This retrospective cohort study included IBD patients hospitalized between July 2013 and April 2015 at a single tertiary referral center where a specialized inpatient IBD care model was implemented in July 2014. In-hospital medical and surgical outcomes as well as postdischarge outcomes at 30 and 90 days were analyzed along with measures of quality of in-hospital care. Effect of specialist IBD care was examined on multivariate analysis.

Results:

A total of 408 IBD-related admissions were included. With implementation of specialized IBD inpatient care, we observed increased frequency of use of high-dose biologic therapy for induction (26% versus 9%, odds ratio 5.50, 95% confidence interval 1.30–23.17) and higher proportion of patients in remission at 90 days after discharge (multivariate odds ratio 1.60, 95% confidence interval 0.99–2.69). Although there was no difference in surgery by 90 days, among those who underwent surgery, early surgery defined as in-hospital or within 30 days of discharge, was more common in the study period (71%) compared with the control period (46%, multivariate odds ratio 2.73, 95% confidence interval 1.22–6.12). There was no difference in length of stay between the 2 years.

Conclusions:

Implementation of specialized inpatient IBD care beneficially impacted remission and facilitated early surgical treatment.
