Patients with inflammatory bowel disease have a high resource consumption, with considerable costs for the healthcare system.
In a system with sparse resources, treatment is influenced not only by clinical judgement but also by resource consumption.
Dr Michael Sulz and colleagues determined the resource consumption of inflammatory bowel disease patients, and identified its significant predictors.
Data from the prospective Swiss Inflammatory Bowel Disease Cohort Study were analyzed for the resource consumption endpoints hospitalization, and outpatient consultations at enrolment and at 1-year follow-up.
The researchers assessed that predictors of interest were chosen through an expert panel and a review of the relevant literature.

The team of doctors reported that for Crohn's disease, fistula, use of biologics and disease activity were significant predictors for hospitalization days.
Age, sex, steroid therapy and biologics were significant predictors for the number of outpatient visits.
For ulcerative colitis, biologics, C-reactive protein, smoke quitters, age and sex were significantly predictive for hospitalization days.
Disease activity and immunosuppressive therapy predicted the number of outpatient visits.
The results of multivariate regressions are shown in detail.
Dr Sulz's team commented, "Several highly significant clinical predictors for resource consumption in inflammatory bowel disease were identified that might be considered in medical decision-making."
"In terms of resource consumption and its predictors, Crohn's disease and ulcerative colitis show a different behaviour."
