Completed Research

Inform Medication Quality Measure Development and Implementation

Validation of an Insulin Adherence/Persistence Methodology

  • Partners: Multi-stakeholder Roundtable
  • Description: Given the known complexity of measuring adherence/persistence to injectable treatments and the lack of a quality measure that assesses adherence/persistence to insulin, PQA convened a multi-stakeholder roundtable to identify potential methodologies that PQA further validated for consideration within a quality performance measure.

Demonstrate the Effectiveness of PQA’s Measures

The Impact of PQA Adherence Measures on Health Outcomes

  • Partners: University of Arizona, Merck & Co.
  • Description: PQA medication adherence measures for hypertension (Renin Angiotensin System (RAS) antagonists), cholesterol (statins), and diabetes medications (excluding insulin) are used to evaluate health plan performance in the Medicare Five-Star Quality Rating System. Limited evidence exists regarding the impact of medication adherence on economic outcomes. Researchers at PQA, the University of Arizona, and Merck & Co. investigated the relationship between PQA’s three adherence metrics on healthcare utilization and expenditures.

Promote Best Practices in Medication Use Quality

Impact of the Appointment-based Model on Health Outcomes

  • Partners: Humana, Publix, and Winn-Dixie
  • Description: The ABM is a pharmacy operations model that utilizes medication synchronization and an appointment with the pharmacist for a medication review. ABMs reduce the number of trips to a pharmacy, improve medication adherence and patient satisfaction. PQA conducted a study to investigate the impact of the ABM of medication synchronization on medical outcomes (e.g., adherence, associated cost) of patients with targeted chronic diseases (e.g., diabetes).

Improving Adult Immunization Rates & EQuIPP

  • Partners: Rite Aid, Humana, Pharmacy Quality Solutions, CECity
  • Description: Adult vaccination coverage rates remain well below Healthy People 2020 targets. Improving vaccination rates requires successful information exchange and care coordination between the multiple critical players: the physician, the pharmacist, and the patient. This study investigated whether a pharmacist-led intervention could improve vaccination rates for pneumonia and influenza among individuals enrolled in Medicare Advantage Prescription Drug plans with Humana, Inc.

Immunization Services Model for Adult Rate Improvement

  • Partners: Scientific Technologies Corporation, Voiceport, Kinney Drugs, Price Chopper, Tops Market
  • Description: This study investigated the impact of telephonic immunization prompts during regular automated outbound communiqués on vaccination rate improvement among adult patients across community pharmacies in the Northeastern US.
