Abstract:
Objective:To evaluate the application of the standard of "Delimitation and Classification of Keshan Disease Areas" (GB 17020-2010, Standard for short), learn about the applicability of its technical indicators and requirements, and provide a basis for revision of the Standard.Methods:In March 2022, provinces with severe epidemic areas of Keshan disease or new cases reported in recent years were selected, including Gansu Province, Inner Mongolia Autonomous Region, Shandong Province, Shaanxi Province, Yunnan Province, Shanxi Province, Liaoning Province, and Chongqing City. Multi-stage stratified sampling method and questionnaire survey were adopted to collect information on the application of Standard by relevant health institutions.Results:A total of 448 questionnaires were collected, including 445 valid. The survey results showed that 87.64% (390/445) of the respondents were aware of the Standard, and 64.72% (288/445) had received training on the Standard. Eighty-two point two per cent (365/445) of the respondents believed that the Standard was simple and easy to operate, 83.82% (373/445) believed that the determination of the diseased townships was scientific and reasonable, and could be effectively implemented, and 83.60% (372/445) believed that the determination of historical epidemic areas was applicable to the current situation of Keshan disease; 38.88% (173/445), 38.20% (170/445), and 37.98% (169/445) of the respondents believed that the classification indicators for classifying epidemic areas (severe, moderate, and mild epidemic areas) were not applicable to the current situation of the disease in the local or provinces with Keshan disease, respectively. Among the indicators for epidemic areas classification, 30.79% (137/445), 29.21% (130/445), and 28.54% (127/445) of the respondents thought that the annual prevalence, the annual number of new cases and the annual incidence were most suitable for classification of Keshan disease areas.Conclusions:The Standard has been applied well in practice. However, based on the current situation of Keshan disease, it is suggested to redefine the standard for the severity of the disease and the classification of historical epidemic areas.
