- Brief Summary
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.
- Detailed Description
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.

- Primary Outcome Measures
Name Time Method Total cost of COPD 1 year Korean won, KRW
- Secondary Outcome Measures
Name Time Method The number of acute exacerbations 1 year Number of events
The cost of alternative medication use three months We will add up the costs of herbal medicine, health supplement, medical equipments and respiratory rehabilitation. According to patients, the items of alternative medication use would be different.
Cost of productivity lost Last 7days from filling out questionnaires Reduction of working hour and monthly income for being late or abscence from work.
Nursing cost 1 year (past 1 year before filling questionnaires) payment for nurse (Korean won, KRW)
EuroQol five dimension(EQ-5D) 3 months Measured by questionnaire based by EQ -5D ( EQ-5D essentially consists of 2 pages - the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS) . The EQ-5D-5L descriptive system comprises the following 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression.
