Accessibility to medical facilities and personnels has been known as one of important determinants of medical care utilization. This study attempted to identify the effects of medical accessibility in terms of geographical distance and occupational opportunity to the medical utilizations. Two-year-experiences of Yonsei University Health Insurance Cooperatives were used as the sources of data. Out patient utilization patterns of 713 members sampled from 4,352 members of Health Insurance Cooperatives were analyzed in order to identify the effects of medical accessibilities. Findings: 1. Average clinic visit rate of Yonsei Health Insurance is 1.66 per person per year. 2. The utilization rates of geographically more accessible group were 33% higher than that of less accessible group. 3. No marked difference in clinic visit rate were observed between medical and non-medical personnel and their family members. 4. Clinic visit rates among occupationally accessible group were slightly higher than those of less accessible. The utilization rate was more sensitively changed by the insurance policy changes in occupationally accessible group.

BACKGROUND AND OBJECTIVES: The development of coronary intervention registry system is required for analysis of current status and more efficient management of patients with coronary artery disease in Korea. We developed database system and registry system in internet environment to confirm the possibility of nationwide system construction and of useful information providing on coronary intervention. MATERIALS AND METHOD: Database for coronary intervention and web-based registry system were developed and installed on internet server. Data elements consist of demographics, coronary risk factors, initial diagnosis, lesion characteristics, type of interventional procedures, and post-procedure outcomes. RESULTS: Total 734 patients were registed by 12 intervention centers from November 1998 to October 1999. Patients with angina pectoris and myocardial infarction were 78.5% and 21.5%, respectively and 14.6% of all patients had history of previous coronary intervention. Major coronary risk factors of the patients were smoking (38.6%), hypertension (33.8%), and diabetes (18.0%). Proportions of the patients with single-vessel disease, two-vessel disease, and triple-vessel disease were 64.7%, 26.2%, and 9.1%, respectively. Left main disease was detected in 2.0%. Balloon PTCA only was performed in 209 patients and 530 patients underwent coronary stent insertion. CONCLUSION: Multicenter data of coronary intervention were collected via internet-based system, and it was possible to construct intervention database. These web-based systems linked with database will provide status of Korean interventional procedures and be able to support multicenter study efficiently by expanding the participating hospitals and including more detailed database fields.
