The purpose of this study was to investigate the distribution of private medical clinics’ income from National Health Insurance and income inequality between them
For the purpose of this study, the data regarding 18,150 private medical clinics’ income from National Health Insurance in 2003 were collected from NHIC database and analyzed. The male doctor’s monthly income from National Health Insurance was higher than that of female doctor. According to the age of medical practitioners, the medical practitioners in 40-45 years of age had the highest income and according to the period of practice, the medical practitioners in 3-5 years of practice had the highest income from National Health Insurance.
According to the location of private medical clinics, the monthly income was highest at the private medical clinics located in medium-sized cities and the monthly income was lowest at the private medical clinics located in metropolitan city areas. Also, the monthly income was highest in the case of ophthalmic clinics, and followed by orthopedic clinics, neurosurgical clinics in order.
The Gini coefficient for distribution of private medical clinics’s income from National Health Insurance was 0.3356 and Robin Hood Index was 26.69%. The Gini coefficient for distribution of private medical clinics’s income was 0.36(ophthalmic clinics), 0.31(general practicing clinics), 0.29(pediatric clinics and internal medicine clinics), 0.27(orthopedic clinics), 0.24(ENT clinics), 0.21(family medicine clinics) in order. These results imply that there would be the large income differentials among specialties and clinics.
In conclusion, the results of this study showed the large income differentials among clinics. This imply a skewed distribution of patients, long waiting time, insufficient utilization of medical resources and inadequate quality of care. Therefore, effective policy measures to reduce the income differentials among clinics should be developed in the near future.
