Evaluation of differences in percentage of international normalized ratios in range between pharmacist-led and physician-led anticoagulation management services.

Background: The safety and efficacy of warfarin depend on maintaining the international normalized ratio (INR) in an established range.

Objective: The purpose was to determine whether a coordinated pharmacist-led approach improved percentage of INRs in therapeutic range in comparison to a physician-led anticoagulation management service (AMS).

Methods: A retrospective chart review was conducted for patients at a multisite primary care organization.
