Analysis of Institutional Factors Influencing Regional Variations in the Cesarean Section Rate
초록
The purpose of this study is to estimate cesarean section rate in Korea and analyze characteristics of health care institution which affect regional variation in the rate. We have searched vaginal and cesarean section deliveries among Diagnosis Related Group dat based upon insurance claim bills which have been submitted to Korean Insurance Corporation for two years since March, 1985. The results are as follows: 1. Out of all delivery cases of 87,500, cesarean section rate was 16.3% (14,299 cases). 2. Cesarean section rate varied according to size and ownership of health care institutions. In above 6- bed sized hospitals, the rate was at about 20% higher than small sized institutions, but rather in hospitals that have more than 500 beds, it was somewhat low. Classified by the hospital ownership, the rate was low at 18.4% in hospitals of religious organization and highest at private or corporate hospitals. 3. This study shows large regional variation in cesarean section rate; there are two times differences between region with the highest and lowest rate. Strongly related factors in that variation was the ownership of health care institution and urbanization variables. Low level of cesarean section rate in a region is explained by high proportion of delivery cases at institutions of religious organization and at insitutions in county level site. This result shows that apart from medical conditions of patients, indications of cesarean section differs from health care providers, and especially ownership of institution strongly affect them. Cesarean section rate in Korea is supposed to be at high level and development of utilization review programs to keep appropriate cesarean section rate is needed.
