Cooperative Study of Hospital Frequency and Character of Transient Ischemic AttacksIII. Variations in Treatment

JAMA. 1977;238(2):142-146. doi:10.1001/jama.1977.03280020046022

Variations in therapy for patients with complaints suggesting transient ischemic attacks (TIAs) among six participating medical centers are described. Selected treatment, based on clinical interpretation of patient characteristics, varied widely among centers. Therefore, results cannot be attributed to specific treatment. Nevertheless, there was little difference between treatment categories and the likelihood of further TIAs. The mortality of the patients who had received anticoagulants was significantly higher (P <.001) than those patients receiving other treatment. Possible reasons for these differences are discussed.
