The American Lung Association of Minnesota (ALAMN) was granted access to a 2004 administrative claims data from an upper mid-Western, independent practice association model health plan. Claims information, including demographics, prevalence, medication and oxygen therapy, and health care utilization, was extracted for 7,782 patients with COPD who were 40 years of age and older. In addition, ALAMN conducted a survey of 1,911 patients from Minnesota diagnosed with COPD. The survey queried the patients about demographics, treatment, medications, limitations, wants, and needs. This article compares and contrasts the information gained through the health plan administrative claims database with the findings from the COPD patient survey in areas of age, gender, types of provider primarily responsible for COPD care, spirometry use, medication therapy, pulmonary rehabilitation, oxygen therapy, and health care utilization. Primary care practitioners provided a majority of the COPD-related care. The claims evidence of spirometry use was 16%-62% of COPD patients had claims evidence of COPD-related medications. 25% of patients reported, and 23% of patients had claims evidence of, a hospitalization during the observation year. 16% of patients reported using pulmonary rehabilitation programs. The results indicate there is an opportunity to improve COPD diagnosis and management.
