The invention discloses a
drug use
correlation analysis early warning method, and the method comprises the steps: firstly building a
drug use
correlation analysis early warning interaction platform which is used for constructing a plurality of databases, evaluating
drug prediction consumption, selecting a dispensable
pharmacy, and encrypting transmission information; and obtaining a callable drug
database in a logistics range through a union set fusion strategy, and generating a predicted consumption threshold through a drug predicted consumption strategy. And when the
medicine consumption exceeds the threshold value, selecting the dispensable drugstores according to the drugstore
selection strategy. The method comprises the following steps of: receiving a key pair, transmitting coordination information containing the key pair by means of a
key distribution strategy, encrypting data by a public key, decrypting the data by a
pharmacy by using a private key, comparing a hash value, distributing if the data are consistent, and feeding back and starting a
retransmission checking mechanism if the data are different. The inventory risk is effectively reduced, the ability to deal with clinical demand fluctuation is improved, and the safety and timely supply of clinical medication are guaranteed.
