We previously published a randomized controlled trial (RCT) where the IDM intervention improved quality of life (QoL) and exacerbation-related outcomes. In this study, we assess the same IDM intervention in a real-world evaluation and identify patient characteristics associated with improved outcomes.Methods: This historical cohort study included patients enrolled for 12 (± 3 months) in the Best Care COPD IDM program. The main outcome was a ≥ 3 point improvement in COPD assessment test (CAT). Secondary outcomes were COPD exacerbations requiring antibiotics and/or prednisone, unscheduled physician visits, emergency department visits and hospitalizations.Results: Data for 571 patients (all patients) were included, 158 met the reference RCT eligibility (RCT matched). Improved QoL was observed in 43% (95% CI:38.9,47.2) of all patients, 47% (95% CI:39.5,55.6) of RCT matched vs 92% (95% CI:79.2,95.1) in the reference RCT intervention arm (n=72). Reductions (12 months IDM vs prior year) were observed in the proportion of patients experiencing exacerbation-related events (all patients): antibiotics/prednisone (− 9.0%,95% CI:-13.9,-3.9); unscheduled physician (− 33.1%,95% CI:-38.2,-27.9); emergency department (− 9.6%,95% CI:-13.5,-5); and hospitalizations (− 6.8%,95% CI:-10.0,-3.7). For the RCT matched group all reductions were comparable to the reference RCT intervention arm. The strongest predictors of improved QoL were baseline CAT, CAT≥ 20 vs CAT< 10 (OR 15.6,95% CI:7.91,30.83), GOLD group B (OR 6.4,95% CI:3.42,11.85) and D (OR 5.64,95% CI:2.80,11.37) vs GOLD group A. Patients with prior antibiotic/prednisone use, FEV1 < 30% predicted and GOLD group D were less likely to have no urgent health service utilization (OR 0.5,95% CI:0.30,0.68), (OR 0.2,95% CI:0.07,0.78) and (OR 0.3,95% CI:0.14,0.51), respectively.Conclusion: Best Care COPD improved QoL and reduced exacerbation-related outcomes in a manner directionally similar to the RCT from which it emanated. Baseline QoL, exacerbation history, and GOLD category were identified as possible predictors of IDM impact and will inform future program development and resource allocation.Keywords: chronic disease management, COPD assessment test, health service utilization, health status, quality of life |
