[Association rules analysis of Fufang Kushen injection in combination with modern medications in treating lung cancer: real-world study based on hospital information].

The present study was aimed to analyze the association rules of Fufang Kushen injection in combination with other modern medications in treating lung cancer based on the electrical medical records in real world clinical situations extracted from hospital information system in Institute of Basic Medical Sciences, China Academy of Chinese Medical Sciences, and provide reference for improving rationality of clinical drug use and exploring the prescription rules as well as subsequent in-depth analysis. The electrical medical records of the hospitalized patients using Fufang Kushen injection for lung cancer were extracted to analyze the frequency distribution characteristics in combined application with western medicine, and Apriori algorithm was used to analyze the specific association rules in combined drug use. A total of 49 597 patients were included in the study. The commonly combined modern medications included 5-HT receptor blockers, antibiotics, chemotherapy drugs, antitumor immune regulating drugs, glucocorticoid drugs and analgesics, which was usually applied in combination with traditional Chinese medications such as those for removing blood stasis, spleen and stomach nourishing drugs, Qi-regulating agent, heat-clearing and detoxifying prescriptions, laxative and Qi invigorating agent in clinical treatment. The results revealed that the distribution characteristics in combined application and association combinations of Fufang Kushen injection had specific rules, consistent with the clinical orientation of this drug in treatment of lung cancer. Such results may provide reference for reasonable application of Fufang Kushen injection in clinical treatment.
