Objective: Rheumatology of Korea has been rapidly advanced in a brief span of 36 years since the subspecialty board certification program was established in 1992.The objectives of this investigation is to analyze the distribution of rheumatology practices in Korean in order to better understand the appropriate supply of the workforce.Methods: Using a membership list of KCR(Korean College of Rheumatology),information of practicing rheumatologist was obtained.We mapped the ratios of rheumatologist to population and patient with rheumatologic disease,using data of Statistics Korea and 2015 HIRA(Health Insurance Review & Assessment service).Results: In 16 administrative districts of Korea,in 2015,there were 311 practicing rheumatologist in a list of member of KCR.There were 218 members practicing in metropolitans and 93 members in provinces.In whole country,mean number of rheumatologist per 100,000 populations was 0.60 and was 0.33 in provinces but was 0.92 in metropolitans.In comparison that number of internal medicine specialist in 2014,difference of between provinces and metropolitans was 1.5 times in internal medicine specialist but was 2.7 times in rheumatologist.And number of rheumatologist per patients that be practiced from 7 groups according to 2015 HIRA data,were 17.21(per 100,000 patients)in metropolitans but were 6.57 in provinces.Conclusion: Because of uneven distribution of rheumatologist,some patients with chronic rheumatic conditions likely have limited access to rheumatology care.So newly policy based approach need to be taken into account to alleviate a disparity.
