The invention provides an interpretable postoperative analgesia formula intelligent recommendation method based on a
decision tree, and the method comprises the following steps: S1, according to hospital postoperative analgesia case data, determining
patient characteristics and analgesia drugs, the
patient characteristics comprising continuous variables and discrete variables, the analgesia drugs being the continuous variables, and preprocessing the case data; s2, performing feature construction and
feature selection on the patient features, and taking the selected patient features and
analgesic drugs as data sources; s3, taking the preprocessed
medical record data as a training sample of a
decision tree algorithm, and performing analgesia formula
model learning to obtain a learned model; and S4, inputting
test case data into the learned model for prediction to obtain a final
analgesic formula. Through application of the
artificial intelligence technology in the field of postoperative analgesia, medical and industrial crossing is promoted, intelligent recommendation of analgesia formula decisions is achieved, and therefore the
workload of doctors in the process of formulating analgesia formulas is greatly reduced.
