Abstract
Several detailed aspects of medical care services during one year (Aug 1, $1982{\sim}$July 31, 1983) were compared between two community health sub-centers; one (A) was served by a local clinician, the other (B) by a trainee of preventive medicine. The results were analysed as follows: 1. Total spells of medical services during the same period in 'A' sub-center was 4,087 and that in 'B' 2,347. Medicaid visitors in 'A' was 1,051 (25.7% of the total), that in 'B' was 250 (10.7%). Significant difference was observed. 2. Average number of visits for the same case in 'A' was 2.0, that in 'B' was 1.4. Average duration of service by day for the same case in 'A' was 3.9, that in 'B' 3.0. 3. Average cost of service for a case in 'A' was 6,770 won, that in 'B' 4,230 won. 4. Difference in age distribution of visitors in the two sub-centers was insignificant. $0{\sim}9$ year group was 38.5% of the total. Difference in distribution by sex (between two sub-centers) was minimal. Male utilisers more than female by ca. 10%. 5. Concerning distribution of visitors by month, utilisation in July, August and September was the highest; the sum of them was 32.7% of the total in 'A' and 32.9% in 'B'. 6. Distribution by diagnoses in 'A' in decreasing order of frequency was Respiratory system diseases (26.1%), Digestive system diseases (23.0%), Diseases of skin and subcutaneous tissue (17.4%), Accidents and poisoning (11.5%) and Diseases of musculoskeletal system and connective tissue (5.4%). That in 'B' was Respiratory system diseases (39.0%), Digestive system diseases (23.0%), Diseases of skin and subcutaneous tissue (14.2%), Accidents and poisoning (10.9%) and Infection and parasitic diseases (9.1%). 7. The 10 most frequent diagnoses comprised 68.5% of the total in 'A' and 65.5% in 'B' 8. Utilisation by accessibility to each sub-center was studied. It is shown that the nearer the distance or the easier the accessibility, the more visits to services. The distinct pattern is manifested in the utilisation in 'A'-Myun.
