Based on 19,060 Medicaid Beneficiaries with newly diagnosed COPD obtained from Medicaid analytic extract files observed during 2005–2008. Asterisks represent significant group differences in COPD-specific healthcare utilization by statin therapy compared with non-users. Adjusted logistic regressions controlled for cohort year, sex, race, age, state, poverty eligibility, multimorbidity number of other clinical conditions, serious mental illness, alcohol, substance abuse, tobacco use, polypharmacy, and county variables, including above high school education (quartiles), unemployment density (quartiles), poverty density (quartiles), metro status, primary care shortage area, mental health shortage area, primary care provider density (quartiles), hospital beds density (quartiles), psychiatric hospital, pulmonologist density, and cardiologist density
