The invention specifically discloses a medication safety assessment method and
system for hypertensive patients, and the method comprises the following steps: extracting one-complaint five-history, medication records, inspection indexes and
outcome data of the hypertensive patients from an electronic health
record system (EHR), carrying out the preprocessing, extracting key entities, and carrying out the
verification of the key entities; constructing a comprehensive
data set of'co-
disease-medication-examination-symptom 'of the patient, identifying a co-
disease combination strongest associated with hypertension, and mining specific adverse reaction signals under the co-
disease combination;
key factors causing adverse reactions or unreasonable medication are attributed through a multi-factor
conditional logic regression or
decision tree model; and based on
common disease combination and multi-factor
logistic regression analysis of one complaint and five histories, performing
pairing t inspection on laboratory indexes, and generating a medication safety report of the hypertension
common disease patient. By adopting the technical scheme, through multi-dimensional
data analysis, specific influence factors causing
adverse drug reaction or unreasonable
drug use are attributed, and accurate
drug use safety guidance is provided for clinicians.
