Abstract

BackgroundChronic obstructive pulmonary disease COPD imparts a substantial economic burden on western health systems. Our objective was to analyze the determinants of elevated healthcare utilization among patients with COPD in a single-payer health system.

MethodsThree-hundred eighty-nine adults with COPD were matched 1:3 to controls by age, gender and area of residency. Total healthcare cost 5 years prior recruitment and presence of comorbidities were obtained from a computerized database. Health related quality of life HRQoL indices were obtained using validated questionnaires among a subsample of 177 patients.

ResultsHealthcare utilization was 3.4-fold higher among COPD patients compared with controls p < 0.001. The -most-costly- upper 25% of COPD patients n = 98 consumed 63% of all costs. Multivariate analysis revealed that independent determinants of being in the -most costly- group were OR; 95% CI: age-adjusted Charlson Comorbidity Index 1.09; 1.01 - 1.2, history of: myocardial infarct 2.87; 1.5 - 5.5, congestive heart failure 3.52; 1.9 - 6.4, mild liver disease 3.83; 1.3 - 11.2 and diabetes 2.02; 1.1 - 3.6. Bivariate analysis revealed that cost increased as HRQoL declined and severity of airflow obstruction increased but these were not independent determinants in a multivariate analysis.

ConclusionComorbidity burden determines elevated utilization for COPD patients. Decision makers should prioritize scarce health care resources to a better care management of the -most costly- patients.
