On New Year's Eve this year, Donghua Software received a notice of undertaking the information system of Vulcan Mountain Hospital. The workload of 2 to 3 months was completed in 9 days. The information management system of Vulcan Mountain Hospital was delivered as scheduled on February 3. Guo Haozhe, senior vice president of Donghua Software, said that it is worth noting that there is a lack of data comparison between patients with the same symptoms between hospitals, and horizontal information sharing has not been achieved. In terms of patient treatment, information sharing also has serious shortcomings, and information sharing must be temporarily established system. To this end, Donghua Software has established a health file and health data sharing platform based on blockchain technology. By using blockchain technology, one party can report and multiple parties can respond quickly, so as to gain time for epidemic prevention and control.
