We examined the impact of education, employment, income, ethnicity, and cohabitation on the risk of suboptimal adherence to inhaled medication, exacerbations, acute admissions, and mortality among COPD patients.METHODS: Using nationwide healthcare registry data we identified 13,369 incident hospital clinic outpatients with COPD during 2008-2012. We estimated medication adherence as proportion of days covered (PDC) one year from first contact. With Poisson regression we computed adjusted relative risks (aRR) of poor adherence and non-use. With Cox regression we calculated adjusted hazard ratios (aHR) of clinical outcomes.RESULTS: 32% were poor adherers (PDC<0.8) and 5% non-users (PDC = 0). Analyses showed a higher risk of poor adherence among unemployed (aRR1.36, 95% CI 1.20-1.54), low income patients (aRR = 1.07, 95% CI 1.00-1.16), immigrants (aRR = 1.29, 95% CI 1.17-1.44), and patients living alone (aRR = 1.17, 95% CI 1.11-1.24). Similarly, non-use was associated with unemployment (aRR = 2.75, 95% CI 2.09-3.62), low income (aRR = 1.37, 95% CI 1.10-1.70), immigrant status (aRR = 1.56, 95% CI 1.17-2.08), and living alone (aRR = 1.53, 95% CI 1.30-1.81). Low education was associated with exacerbations (aHR = 1.21, 95% CI 1.10-1.35) and admissions (aHR = 1.22, 95% CI 1.07-1.38). Low income was associated with admissions (aHR = 1.20, 95% CI 1.09-1.32), and death (aHR = 1.11, 95% CI 0.99-1.25). The unemployed and those living alone had lower exacerbation-risk but higher mortality-risk.CONCLUSIONS: In Denmark, health equity is a stated priority in a public health care system.
