Background and Purpose-Physician prescribing patterns change slowly despite published randomized trials and consensus guidelines. We measure the effect of Management of Atherothrombosis With Clopidogrel in High-Risk Patients (MATCH) trial on discharge prescribing patterns for patients with stroke and those with transient ischemic attack in the Get With The Guidelines (GWTG)-Stroke Program. Methods-We analyzed discharge prescribing patterns of antithrombotic medications for patients admitted with ischemic stroke or transient ischemic attack at hospitals participating in GWTG-Stroke between October 2002 to January 2006. Clinical information by quarter was analyzed in relation to publication of the MATCH study. Frequency of discharge prescription of aspirin+clopidogrel post-MATCH publication was compared with the pre-MATCH period after adjusting for patient and hospital characteristics and clustering by hospital. Results-A total of 107 872 patients at 632 sites were eligible to receive antithrombotic therapy at discharge. Use of aspirin+clopidogrel therapy declined from 22.4% to 15.4% of patients after the publication of MATCH (adjusted OR 0.62, 95% CI 0.56 to 0.70, P<0.0001). Analysis by quarter revealed a rapid and sustained decrease in use of aspirin+clopidogrel therapy for the remainder of the study period. Conclusions-A rapid and sustained reduction in the frequency of aspirin+clopidogrel use in ischemic stroke and transient ischemic attack was observed after publication of the MATCH trial in the absence of MATCH-specific GWTG-Stroke initiatives and preceding an American Heart Association guideline update.
