Blockchain provides highly secure and reliable data access environment. In blockchain, several data fragments are packed into one block and all blocks are connected to form the chain of blocks. In our prototype, each event of resident such as birth, moving, employment and so on, is assigned to data fragment and certain amount of data fragment, says 20 fragments are packed into block. We also developed the web application interface to avoid installing any applications in users’ PC or smartphone. Prototype development proved the possibility to use the blockchain technology to large amount of data management system with highly secure and reliable features.展开更多

MethodsThe questionnaire consisting of prevalence, awareness rate, management rate, behavior correct rate, control rate, and medicine obey was used to survey the chronic disease condition in 2009. A total of 809 736 residents were randomly selected from Shanghai and Guangdong, China. ResultsThe hypertension prevalence was 17.81%. From sex analysis, the female has higher rate than male in hypertension prevalence, understand rate, management rate, behavior correct rate, control rate, and medicine obey rate. From age analysis, the prevalence, understand rate, management rate, control rate, and medicine obey were increasing along with the age, but behavior correct rate was not in this condition. The diabetes prevalence was 6.92%. To compare with Shanghai and Guangzhou in 5 aspects, the prevalence of chronic diseases was alike. Except lower behavior correct rate in Shanghai, management rate, behavior correct rate, control rate, and medicine obey rate were higher in Shanghai. ConclusionThe government must take main principle in chronic disease control. Base construction of community health management and increase management level of chronic diseases should be enhanced and practitioner's knowledge of chronic disease management should also be enhanced.展开更多
