OBJECTIVES: The research is to analyze social demographic characteristics and health service use nature of Parkinson’s disease in Korea by using Korean National Health Insurance Claims dataset (HIRA-NPS 2013), which is one of the secondary sources of health and medical treatment provided by reimbursement authority, and to measure a direct medical costs of Parkinson’s disease. METHODS: Patients with primary or secondary disease code for Parkinson’s Disease according to Korean Standard Classification of Disease (KICD-10 code : G20) are selected from National Patients Sample Dataset. The characteristics of age, sex, length of stay for inpatients, the number of outpatient visit and medical cost were analyzed based on the patient dataset extracted. SAS 9.2 (SAS Institute Inc., Cary, NC, USA) was used for statistical analysis. RESULTS: The number of patients with Parkinson’s disease for the analysis was 4,137, and that of claims cases for 12 months was 34,259. The average age of the patients was 71.6 years old and the female patients composed 60.11%, which was about 1.5 times that of the male patients. The prevalence rate of Parkinson’s disease per 1,000 populations was 3.54 in 2013. Based on 1-year claims dataset, outpatient visit days were 9.83 and inpatient hospitalization days were 25.3. The annual direct medical costs were USD 487 for an outpatient and USD 10,429 for an inpatient. CONCLUSIONS: As the result, the Parkinson’s disease is the economic burden in aging society in Korea. The limitation that the sample data used for the research is smaller than the raw data should be considered. Therefore further analysis on Parkinson’s disease in aging society is needed.
