区块链技术在分级诊疗中的应用研究

The establishment of hierarchical diagnosis and treatment(HDT) platform based on data sharing is an effective measure to solve the equalization of basic medical services, optimize the allocation of medical resources, and reduce the cost of medical services. It is also an effective way to alleviate the problem of expensive and difficult medical treatment. There are many problems in the traditional HDT scheme of centralized deployment, such as unclear responsibilities and rights, difficult supervision, data leakage, mutual trust of institutions, difficult traceability, etc .To solve these problems, a new hierarchical diagnosis and treatment scheme based on blockchain is proposed. The role and application mode of blockchain technology in the construction of HDT system is explicated in my paper. The integration of blockchain and HDT system can perfectly realize the sharing of medical resources, the interconnection of medical and health information and the full cycle supervision of data in the region by taking advantage of the advantages of the decentralization of blockchain, the non tamperability of data, the traceability of data, the guarantee of data privacy and the full credibility of data.
