Study Summary

This is a prospective, single-arm, feasibility pilot study of 20 participants (aged 60 years or older, with additional stroke risk factors and 'actionable' undertreated AF) recruited from a total of 4 retail and outpatient community pharmacies. Eligible participants will be enrolled in a 3-month active intervention of pharmacist-led OAC management. Participants will be passively followed for an additional 9 months to determine safety endpoints.

  4. AF and on sub-optimal or inappropriate OAC therapy

  5. Written informed consent

Exclusion

Exclusion Criteria:

  1. AF on optimal OAC therapy

  2. OAC required for other conditions (i.e. DVT/PE, PCI in prior year, left ventricularthrombus, etc.)

  3. Currently taking two antiplatelet agents

  4. Uncontrolled hypertension (defined as SBP ≥160 mmHg x 2 BP readings measured atscreening)

  5. End-stage renal disease (CrCl <15 ml/min or dialysis)

  6. Major surgery in prior month (defined as surgery requiring general anesthesia andovernight inpatient hospital stay)

  7. History of "major bleeding" in prior year (defined as overt bleeding at criticalsite including intracranial, intraspinal, intraocular, pericardial, GI bleed, bleedrequiring hospitalization, bleed resulting in ≥20 g/L drop in hemoglobin orrequiring transfusion of ≥2 units packed cells)

  8. Excess alcohol intake (≥8 alcoholic drinks/week)

  9. Inability to read or understand English or Spanish

  10. Participants considered unreliable by the Investigator or designated pharmacy teammember concerning the requirements of follow-up, or those with foreshortened lifeexpectancy precluding 3-month follow-up

  11. Severe cognitive impairment (≥5 errors on the Short Portable Mental StatusQuestionnaire)

  12. Pregnant women

Study Description

Oral anticoagulation therapy for stroke prevention in AF is safe and effective but under-utilized. Optimal delivery of existing therapies would prevent AF-related stroke. Therefore alternative strategies to increase adherence to current guidelines for OAC use for AF stroke prevention should be explored.

Accumulating data indicate that pharmacist-led or pharmacist-collaborative care in cardiovascular disease monitoring, risk factor control, and medication optimization leads to greater adherence to guideline-directed targets and improved outcomes.

In this prospective, single-arm, feasiblity pilot study the investigators intend to enroll 20 participants (aged 60 years or older, with additional stroke risk factors and 'actionable' undertreated AF) from a total of 4 retail and outpatient community pharmacies in Los Angeles. Eligible participants will be enrolled in a 3-month active intervention of pharmacist-led OAC management. Participants will be passively followed for an additional 9 months to determine safety endpoints.

The primary objective(s) will be to determine the prevalence of 'actionable' AF in the community and the proportion of patients receiving guideline concordant OAC therapy at 3 months. Secondary outcomes include: patient satisfaction with pharmacist services (at 3 months), pharmacists' perspective on study implementation (at 1 month and 3 months), OAC adherence (at 12 months), and healthcare utilization (at 12 months).

This research will generate new knowledge on an innovative, and potentially sustainable stroke prevention strategy to increase evidence-based use of OAC therapy in patients with AF.
