BACKGROUND: The Statin Use in Persons with Diabetes (SUPD) measure, developed and endorsed by the Pharmacy Quality Alliance and National Quality Forum, has been adopted by the Centers for Medicare & Medicaid Services as part of the star rating measure set. It was added as a display measure in 2015 and, as of 2019, has become a star measure. Clinical pharmacy specialists (CPS) embedded in the patient-centered medical home (PCMH) are well positioned to review and recommend statin therapy for patients with diabetes in order to improve patient care and health plan performance.OBJECTIVE: To improve rates of statin prescribing and performance on the SUPD measure in the Denver Health Medical Plan (DHMP) population with diabetes by creating a CPS-led intervention to initiate statin prescriptions in eligible patients.
