Randomized Controlled Trial Multicenter Study Clinical TrialDo anticoagulation management services improve care? Implications of the Managing Anticoagulation Services Trial.
An Anticoagulation Clinic Service (ACS) has been proposed as one strategy for improving warfarin treatment for patients with atrial fibrillation. In the Managing Anticoagulation Services Trial (MAST), ACSs meeting specifications for high quality care were established in six managed care organizations (MCOs) which had the patients and resources to support this initiative. The trial followed 1165 patients age >or=65 years who had atrial fibrillation as the primary reason for anticoagulation and were enrolled in a participating MCO. ⋯ In both practice clusters, patients had subtherapeutic INR values (1.5 to 1.99) about one fourth of the time. Providing an ACS in a managed care setting did not appear to improve anticoagulation care over the usual care provided at the sites in this trial but could be a reasonable consideration in a practice setting where time in target range is less than 50%. A higher rate of utilization and a more aggressive stance toward subtherapeutic INR values could potentially enhance the effectiveness of an ACS.
