Geographic Variations in Tonsillectomy and Adenoidectomy (T&A) and Appendectomy in Korea

The objectives of this study are two-fold : to identify geographic variations in the rate of tonsillectomy and adenoidectomy (T&A) and appendectomy and analyze the socioeconomic variables and health resources which affect geographic variation in the rate. The nationwide three month's cases of the two surgical procedures in 1991 are obtained from the record of the National Federation of Medical Insurance. The analysis shows two to ten-fold variations in the regional rates for the performance of two common procedures such as T&A and appendectomy. T&A shows a bigger regional variations than appendectomy. As a result of multiple regression, the factor of bed supply has been found significant for the dependent variable of the rate of T&A. The finding of large variations in the rate of surgical procedures throughout the country would have important implications for allocating scarce resources and managing quality of care. Further analysis is needed for the elaboration of the above implications.
