Economic Burden Of Fatigue In Inflammatory Bowel Disease

Background This retrospective study gathered medical/pharmacy claims data on patients with IBD between 01/01/2000 and 03/31/2019 from the IBM® MarketScan® commercial claims database to assess the real-world impact of fatigue on healthcare costs in patients newly diagnosed with inflammatory bowel disease (IBD). Methods Eligible participants were ≥18 years, newly diagnosed with IBD (≥2 separate claims) and had ≥12 months of continuous database enrollment before and after fatigue diagnosis. The date of fatigue diagnosis was the index date; participants were followed for 12 months post-index. Patients with (cases) or without (controls) fatigue were matched 1:1 by propensity score matching. Patients with evidence of prior IBD diagnosis/treatment, or those with a chronic disease other than IBD wherein fatigue is the primary symptom, were excluded. Healthcare resource utilization (HCRU), including hospitalizations, inpatient and outpatient visits, and associated costs was compared between cases and controls. Results Matched IBD cohorts (21,321 cases/21,321 controls) were identified (42% CD and 58% UC) with similar baseline characteristics (average age: 46 years; 60% female). Cases versus controls had significantly more all-cause outpatient visits (incidence rate ratio [IRR], 95% confidence intervals [95% CI]: 1.64 [1.61, 1.67], P Conclusions Presence of fatigue is associated with an increase in HCRU and total medical costs among patients newly diagnosed with IBD.
