Purpose: This study aimed to measure the true burden of COPD by calculating incremental direct and indirect costs. Direct medical resource use, productivity metrics, and COPD-specific resource use and costs were also evaluated.
Patients and methods: This was a retrospective, observational, matched cohort study using administrative claims data from the Truven Health MarketScan® Commercial Claims and Encounters and the Health and Productivity Management databases (2007-2010). Working-age (18–65 years) patients with COPD were identified as having at least one hospitalization or one emergency department visit or two outpatient visits. Patients in the non-COPD cohort did not have a diagnosis of COPD during the study period. Outcomes were evaluated in the first full calendar year after the year of identification (index).
Results: Of the 5,701 patients with COPD identified, 3.6% patients were frequent exacerbators (≥2), 10.4% patients were infrequent exacerbators (1), and 86% patients were non-exacerbators (0). When compared with the 17,103 patients without COPD, the incremental direct cost of COPD was estimated at $6,246/patient/year (95% confidence interval: $4,620, $8,623; P<0.001). Loss in productivity was significantly greater in patients with COPD, with an average of 5 more days/year of absence from work and incremental indirect costs from short-term disability of $641 (P<0.001). Direct costs for frequent exacerbators ($17,651/year) and infrequent exacerbators ($14,501/year) were significantly higher than those for non-exacerbators ($11,395, P<0.001).
Conclusion: Working-age patients with COPD incur statistically significantly higher direct and indirect costs and use more resources compared with those who do not have COPD.
