Background

The aim of the study was to examine the prevalence of and factors associated with antidepressant (AD) prescriptions in order to draw a comprehensive picture of prescribing practices in Switzerland.

Method

We extracted clinical, patient, and resource consumption data from the Swiss IBD Cohort Study between 2006 and 2016. Average unit costs for IBD-related events were derived from Swiss claims data and pharmaceutical price lists. We used multivariate regression, controlling for patient-level characteristics, to estimate trends and determinants of direct and indirect costs and resource utilisation.

Results

We included 2365 adults diagnosed with Crohn's disease [CD; N = 1353] and ulcerative colitis [UC; N = 1012]. From 2006-16, mean health care expenditures per patient per year were 9504 euros [70% drugs, 23% inpatient, 7% outpatient] for CD and 5704 euros [68% drugs, 22% inpatient, 10% outpatient] for UC. Health care costs increased by 7% [CD] and 10% [UC] per year, largely due to rising pharmaceutical expenditures driven by increased biologic agent use. Inpatient, outpatient, and indirect costs fluctuated and did not offset increased pharmaceutical costs. Disease characteristics were important predictors of costs.

Conclusion

Increased expenditure for IBD was marked by a shift towards greater pharmaceutical management over the past decade. This study highlights the need to identify cost-effective treatment strategies in the face of increased uptake and expenditures associated with innovative treatments.
