RESUMEN
OBJECTIVE: This study aimed to evaluate the impact of a pharmacist population health initiative on the ability to increase the percentage of patients with atherosclerotic cardiovascular disease (ASCVD) who are on an appropriate statin. SETTING: Ten primary care clinics in Southwest Washington. The average payer mix across the included clinics is 47% Medicare, 26% commercial, 22% Medicaid, 2% self-pay, and 3% other. Reimbursement-tied statin quality metrics are present in 14.1% of patients' insurance contracts. PRACTICE DESCRIPTION: The primary care pharmacy collaborative drug therapy agreement allows pharmacists to act as prescribers by permitting initiation, adjustment, and monitoring of medication therapy, with the authority historically stemming from referral by the patient's primary care provider to the pharmacist. PRACTICE INNOVATION: A novel, population health protocolized prescriptive authority (PPA) initiative was implemented, of which a key component was expanding pharmacists' prescriptive authority to prescribe statins for population health initiatives. Without referral, pharmacists screened, directly outreached to, and prescribed statins for patients with ASCVD who were not on a moderate- or high-intensity statin. Electronic health record (EHR) documentation was updated to better reflect the patient's history and increase metric accuracy. EVALUATION: A retrospective analysis of a population health initiative from October 1 to December 31, 2018. The initiative was evaluated on the combined success of initiating patients with ASCVD on moderate- or high-intensity statins and the acceptance rate of EHR corrections. RESULTS: The pharmacy team screened 510 patients. Appropriately dosed statins were initiated for 40.0% of patients, and the EHR was accurately updated in 91.9% of instances. These combined efforts demonstrate 50.5% overall success of pharmacist interventions. CONCLUSION: Expanding pharmacists' authority to PPA for statin medications in patients not meeting quality metrics increased the number of successful interventions. Pharmacists make a major contribution on improving population health metrics for statins.
