Evaluating a Pharmacist-Led Intervention on Cardiovascular- and Diabetes-Related Quality Measures in a Primary Care-Based Accountable Care Organization

Abstract

Background:

The Centers for Medicare and Medicaid Services (CMS) publishes quality measures to gauge performance in Accountable Care Organizations (ACOs). ACO-27 (Diabetes Mellitus: Hemoglobin A1c Poor Control) and ACO-41 (Diabetes: Eye Exam), are 2 components for the Diabetes Composite measure. ACO-42 focuses on Statin Therapy for the Prevention and Treatment of Cardiovascular (CV) Disease. There are limited studies regarding the pharmacist role in CV and Diabetes Management in the ACO primary care setting.

Objective:

To evaluate the impact of pharmacist-led interventions on CV- and diabetes-related CMS quality measures within a primary care-based ACO.

Methods:

This retrospective pre-post intervention study included 3 primary care-based ACO offices. Patients who met eligibility criteria for CMS quality measures ACO-27, -41 and -42 were included. Pharmacist interventions occurred in December 2018. The study co-primary outcomes were the percentage of patient meeting ACO-27/-41 (composite diabetes-related) and -42 (statin-related) CMS quality measures in the pre-intervention compared to the post-intervention phases.

Results:

Of 105 patients meeting study inclusion criteria, 77.1% were on statin therapy prior to intervention. After pharmacist intervention, the prevalence of patients on statin therapy increased to 80.0% (p = 0.083). All patients had a HbA1c less than 9% pre-intervention. Sixty-one (58.1%) patients had a documented dilated eye exam prior to intervention. Post-intervention, the prevalence of exams increased to 73.3% (p < 0.0005).

Conclusions:

Pharmacists can assist primary care providers in the ACO setting meet CV- and diabetes-related CMS quality measures, demonstrating the value of the pharmacist in value-based health care settings.
