Abstract |
Objectives Through quantitative analysis of the main computerized national immunization registry in Korea in operation since 2000, this study was performed to propose methods of improving the national immunization registry.
Methods Data for the analysis was collected from the computerized national immunization registry system from 1 Jan. 2001 to 31 Dec. 2006. Among the data collected, we sampled immunization data of children from the ages of 0-12 years (as of 31 Dec. 2006). Then we selected only data registered by public health centers.
Results The number of registrations gathered by the computerized program for immunization registry was 4,762,685, which represents 63.0% of the total population from resident registration (as of 31 Dec. 2006). The analysis of this data revealed a 12.11% rate of error for personal information such as age, sex, address and a 1.19% rate of incompleteness for vaccination related information. Furthermore, in 26.3% of the cases, the entry into the immunization registry of the vaccination occurred on the same day the vaccinations occurred, and 23.7% of the time, within 1~7 days of the vaccinations. Consequently 50% of immunization data was registered into the immunization registry within 1 week of the vaccinations.
Conclusion There first needs to be considerable improvement in data gathering and data entry if the national immunization registry program is to be succeed. Participation by private medical providers who represent 60% of vaccination services is necessary and the role of public health centers should be changed to improve the program. In addition, the central government needs to invest in the private sector's participation in the registry and the education of the public and its view of the vaccination registry. The only public health center had to take part in immunization registry till now because there are limited resources. Now, the authorities must try to increase utility of registered data and improve quality of vaccination services if only there are accumulated data. |
