The invention discloses a
tumor patient regional collaborative follow-up visit method and
system based on hierarchical diagnosis and treatment, and belongs to the technical field of
medical health information processing, and the method comprises the steps: obtaining the original clinical data of a
tumor patient, and extracting an encrypted local gradient vector and a mechanism identifier; inputting the encrypted local gradient vector into a federated aggregation
server, and outputting a global risk
feature vector; according to the global risk
feature vector and the real-time regional resource parameters, calling a target grading evaluation model, and outputting a diagnosis and treatment hierarchy identifier; calling a target
referral path optimizer according to the diagnosis and
treatment level identifier and the real-time
medical institution service capability data, and outputting a minimum-cost
referral path; based on the minimum-cost
referral path and the diagnosis and
treatment level identifier, generating a referral scheduling instruction and issuing the referral scheduling instruction; and acquiring execution feedback data after the referral scheduling instruction is executed, inputting the execution feedback data into the federal aggregation
server, and updating the encrypted local gradient
vector generation parameters and the model weight parameters. The medical
resource utilization efficiency is improved.
