Sponsored by Konkuk University Medical Center · Observational
The purpose of this study is to estimate a direct/indirect medical cost and to provide evidence establishing efficient strategies to reduce medical costs of COPD in Korea.
This study is a multi-center research on economic burdens of COPD for a year. It is composed of three phases detailed as follow.
Phase 1: Direct Cost Estimation in COPD patients (N = 400) Direct cost determined as amount of money expended to medical institutes for treatment. Estimated costs, based on the information from Health insurance review agency(HIRA) and The National Health and Nutrition Examination Survey (NHANES) data, are collected.
Phase 2: Indirect cost Estimation by Sampling Survey in COPD patient Indirect cost is extra-expanses excluding hospital fees, including cost for transportation, medical instruments, home care services and loss of labor capacity reduction. The information was collected by structured questionnaire for 12 weeks.
Phase 3: Direct/Indirect cost is validated and analyzed based on the collected information from phase 1 and 2 according to severity defined by the GOLD guideline.
3,303 studies on the registry are indexed under Lung Diseases; 355 are open to participants now.
This study's enrollment of 390 is above the median of 157 across 929 observational studies indexed under Lung Diseases.
