RESUMO
BACKGROUND: Costs of using eHealth in inflammatory bowel disease (IBD) management has only been assessed for short follow-up periods. The primary aim was to compare the direct costs of eHealth (cases) relative to standard care (matched controls) for IBD during three years of follow-up. METHODS: The study design was a retrospective, registry-based follow-up study of patients diagnosed with IBD two years prior, and three years subsequent, to their enrolment in eHealth. Cases were matched 1:4 with controls receiving standard care based on diagnosis, gender, biologics (yes/no) and age (+/- 5 years). RESULTS: We identified 116 cases (76 (66%) with ulcerative colitis (UC) and 40 (34%) with Crohn's disease (CD)) and matched them with 433 controls. IBD-related outpatient costs were only significantly higher for cases in the year of their inclusion in eHealth (2,949 vs. 1,621 per patient, p =.01). Mean IBD-related admission costs tended to fall after enrolment in eHealth, with mean admission costs per patient at year 3 of follow-up of 74 for cases and 383 for controls (p = .02). Linear extrapolation of the reduction in costs beyond year 3 after enrolment in eHealth revealed that eHealth would be cost neutral or saving, relative to standard care, from year 4. CONCLUSION: IBD-related outpatient costs in both groups were similar and only significantly higher for cases in the year of their enrolment in eHealth, with admission costs typically falling after a patient's inclusion in eHealth. Estimation revealed eHealth to be cost neutral or saving from year 4.
