ObjectiveTo realize the application status and development trend of oral anticoagulant drugs used in respiratory diseases in 72 hospitals in 6 cities from the year 2013 to 2017.MethodsFrom January 2013 to December 2017, we randomly selected the electronic information from 10 working days per quarter in 6 cities including Beijing, Guangzhou, Shanghai, Chengdu, Shenyang, and Zhengzhou, with 12 hospitals in each city, and summarized the information into the prescription database of the hospital prescription analysis project. Through the hospital information system, we screened out the information of outpatient prescriptions and inpatient medical records which used oral anticoagulants. The prescriptions with respiratory diseases related-diagnosis were selected as the research objects by manual screening. The application of oral anticoagulant drugs used in respiratory diseases was statistically analyzed by drug amount, prescription amount, prescribed daily dose (PDD), and defined daily dose (DDD).ResultsFrom 2013 to 2017, the number of warfarin sodium prescriptions was successively 4 769, 5 747, 7 549, 7 261, and 7 151, which had been always ranked the first in the five years, but decreased year by year since 2015. The proportion of warfarin sodium drug use amount decreased year by year from 32.52% in 2013 to 5.03% in 2017. The proportion of prescription and drug consumption sum of new oral anticoagulants increased year by year in the past five years. The PDD/DDD of warfarin sodium, dabigatran etexilate, rivaroxaban, and apixaban were 0.41, 0.73, 0.68, and 0.33, respectively. There were off lable use of new oral anticoagulants.ConclusionsWarfarin still dominates the proportion of oral anticoagulants prescribed in the 72 hospitals in the 6 cities in the five years. The clinicians have made a comprehensive judgment after fully considering the safety, effectiveness, and economy of drug use when formulating drug treatment programs.
