Abstract: Background and objective: The aim of this study was to estimate the direct medical costs of COPD in two public health clusters in Singapore from 2005 to 2009. Methods: Patients aged 40 years and over, who had been diagnosed with COPD, were identified in a Chronic Disease Management Data-mart. Annual utilization of health services in inpatient, specialist outpatient, emergency department and primary care settings was extracted from the Chronic Disease Management Data-mart. Trends in attributable costs, proportions of costs and health-care utilization were analyzed across each level of care. A weighted attribution approach was used to allocate costs to each health-care utilization episode, depending on the relevance of co-morbidities. Results: The mean total cost was approximately $9.9 million per year. Inpatient admissions were the major cost driver, contributing an average of $7.2 million per year. The proportion of hospitalization costs declined from 75% in 2005 to 68% in 2009. Based on the 5-year average, attendances at primary care clinics, emergency department and specialist clinics contributed 3%, 5% and 17%, respectively, of overall COPD costs. On average, 42% of the total cost burden was incurred for the medical management of COPD. The share of cost incurred for the treatment of conditions related and unrelated to COPD were 29% and 26%, respectively, of the total average costs. Conclusions: COPD is likely to represent a significant burden to the public health system in most countries. The findings are particularly relevant to understanding the allocation of health-care resources and informing appropriate cost containment strategies. © 2011 Asian Pacific Society of Respirology.
