[Analysis about characteristics of drug used in clinical for ischemic stroke patients based on hospital electronic medical database].

There are many different kinds of drugs which can treat ischemic stroke. This study aims to analyze the clinical treatment of ischemic stroke using Chinese and western medicines and their combination scheme. Data abstracted from 15 national 3a grad hospitals' hospital information system (HIS) databases were collected, then were used frequencies to find the common used drug and type, and were used association rules to anylizs the common combined medication scheme of Chinese and western medicines. It was found that the Shuxuetong (9 015 cases, 22.66%), Danhong (7 369 cases,18.53%) and Xueshuaitong (5 302 cases,13.33%) injections were the most frequently used drugs, and blood-activating and stasis-dissolving prescription (30 384 cases, 76.39%), resuscitative prescription (6 850 cases,17.22%) and tonic prescription (5 997 cases,15.08%) were the most commonly used types of Chinese medicine. The oral dose of aspirin (20 924 cases, 52.60%), Guangxi pp injection (10 771 cases, 27.08%) and insulin injection (10 599 cases, 26.65%) were frequently used. And the types of antiplatelet agents (23 049 cases, 57.95%), vasodilator (19 608 cases, 59.29%) and antihypertensive drug (15 475 cases, 39.90%) were commonly used. The drug combination of aspirin, twenty five pearl pill, Danhong and Xueshuaitong injection were the most frequently used group and its confidence coefficient is 97.5%. The type combination of blood-activating and stasis-dissolving prescription, thrombolytic drug, insulin and vasodilator was the most commonly used group and its confidence coefficient is 97.424%. This study concludes that the drug combination of aspirin, twenty five pearl pill, Danhong and Xueshuaitong injection and the type combination of blood-activating and stasis-dissolving prescription, thrombolytic drug, insulin and vasodilator were commonly used in clinical.
