Community-Based Pharmacist Anticoagulation Clinic Outcomes Compared with Physician Management

Area of Science:

• Pharmacology
• Clinical Pharmacy
• Internal Medicine

Background:

• Warfarin is a critical anticoagulant for specific conditions like mechanical mitral valve replacement and antiphospholipid syndrome.
• Pharmacist-led management of anticoagulation therapy is increasingly recognized in clinical settings.
• Collaborative Practice Agreements (CPAs) enable pharmacists to provide comprehensive anticoagulation services.

Observation:

• A quasi-experimental study compared warfarin management by community-based pharmacists under a CPA versus traditional physician management.
• Time in Therapeutic Range (TTR) was assessed retrospectively and prospectively.
• Patient satisfaction surveys were administered to evaluate experiences with both management models.

Findings:

• Pharmacist management achieved a Time in Therapeutic Range (TTR) of 60.7%, statistically equivalent to physician management at 59.4% (p=0.829).
• Patient satisfaction data indicated a slight preference for management by pharmacists over physicians.
• The study included 37 patients, with 26 in the pharmacist group and 11 in the physician group.

Implications:

• Community-based pharmacists can achieve comparable warfarin control to physicians, suggesting expanded roles in anticoagulation management.
• Pharmacist-led anticoagulation clinics offer a patient-centered approach with equivalent clinical outcomes.
• Integrating pharmacists into anticoagulation care models can enhance accessibility and patient satisfaction.
