Use method of blockchain-based hospital information system

The invention relates to a use method of a blockchain-based hospital information system. The present invention provides a hospital information system. In the case of a medical oncology, the service modules of the hospital information system includes a pain screening module, an analgesic prescription control module, a follow-up tracking information input module, a subsequence hospital departure follow-up tracking module and a query statistics module; the information system sequentially loads and executes the codes of the above modules according to the calling logic of a configuration file; executable codes corresponding to the modules in a code area are sequentially read; and the calling relations of the executable codes corresponding to the modules are determined according to the order ofblocks in a chain, the codes of the corresponding modules are executed, and the hospital information system is updated. The hospital information system of the present invention sequentially calls andaccesses the service modul
