| Summary: | 碩士 === 國立陽明大學 === 醫務管理研究所 === 87 === The National Health Insurance (NHI) had been implemented for more than three years. During last three years, public attitude to NHI was ranked high relative to other public policies made by the government. However, this increased preference toward NHI also accompanied with high utilization rates and sky-high health care expenditure of Taiwan. Therefore, National Health Insurance Bureau (NHIB) began to implement another cost containment strategy called Global Budgeting (GB). Since the GB only applies to dental services, many policy makers and clinical practitioners wonder whether this system will works. The major purpose of the study is to investigate the impact of GB in use and cost containment of dental services. Results of the study can be used as a preliminary findings for NHIB and policy maker to change or to improve this GB system.
Data used in this study are extracted from dental claim data from April 1998 to September 1998 collected by NHIB, Taipei office. 3,923,902samples were included in data analysis. Analysis of Variance (ANOVA) was applied to assess the impact GB on utilization and expenditure of dental services. Results of this study indicate that:
1. Utilization and expenses dental services did not reduce even after the implementation of the GB system.
2. Averaged cost of per visit was also increased after the implementation of the GB system.
3. Items or methods of treating dental patients had changed slightly.
These results suggest that current GB system may not be as good a system as it is expected. A major revision is necessary if these results keep progressing.
