Anti-coagulation clinic


The goal of the Anticoagulation Management Service (AMS) is to provide a focused, coordinated approach to managing anticoagulation therapy to improve patient outcomes.

Responsibilities of the AMS pharmacists are:

  • To improve the efficacy and safety of warfarin therapy.
  • To help determine the appropriateness of anticoagulation therapy.
  • To manage the dosing and monitoring of warfarin anticoagulation.
  • To provide systematic monitoring of patients receiving warfarin therapy.
  • To provide comprehensive and ongoing anticoagulation education for patients and caregivers.
  • To communicate anticoagulation-related information to the patient's primary care provider.


Our outpatient clinic opened the doors in September of 1999 with 35 patients. Our operations have grown, and we now service over 1,500 patients. We are the Group Health preferred provider for anticoagulation in the Yakima Valley, and we accept all major insurance plans including Medicare and Medicaid.


Our clinic is staffed by pharmacists with advanced clinical training and specialty certification in anticoagulation management.
