To improve the genetic algorithm and innovate the recommendation model,mine the core prescriptions and recommend the effective prescriptions based on the electronic medical records data of type 2 diabetes mellitus(T2DM).
Based on the real-world electronic medical records data,the database of effective prescriptions of T2DM patients and original prescriptions of different syndromes was constructed. The genetic algorithm was improved and the construction of fitness function was optimized,so the extracted core effective prescriptions can evolve towards the collection of effective prescriptions. Based on the similarity relationship between the core effective prescriptions and the collection of original prescriptions,the recommendation model was innovated,and the prescription recommendation was mined by traversing the collection of original prescriptions of different syndromes.
A total of 17 712 prescriptions with effective diagnosis and treatment standards were used,and 37 kinds of traditional Chinese medicines were extracted. Finally,26 prescriptions with “recommendation value≥85%” were excavated,and the maximal recommendation value was 97.26%.
In this study,the improved genetic algorithm has improved the ability of feature extraction and global search for prescription sets of traditional Chinese medicine,and proposed a new recommendation model for clinical prescriptions decision-making,thus improving the utilization rate of electronic medical records data.
