Impact of pharmacist alternative therapy interventions in a pediatric Medicaid population

BACKGROUND: Ambulatory clinical pharmacists are viewed as the medication experts on the health care team and frequently assist with medication access concerns. However, medication access and insurance navigation are difficult because of wide variations in insurance formularies. Accountable care organizations (ACOs) incorporate pharmacists as members of their population health teams to assist with these efforts. These ACO pharmacists are uniquely positioned to assist pediatric ambulatory care pharmacists with medication access concerns. This collaboration has the potential to not only improve patient care but also provide cost savings. OBJECTIVE: To estimate cost savings to an ACO derived from alternative therapy interventions made by pharmacists embedded in pediatric ambulatory clinics, using resources created by ACO pharmacists, within a pediatric Medicaid population. The secondary objectives were to quantify the frequency of alternative therapy interventions provided by these pharmacists, evaluate the impact on medication access through the avoidance of prior authorizations (PAs), and assess the frequency and cost savings of alternative therapy interventions per treatment category. METHODS: This was a retrospective review of alternative therapy interventions provided by pediatric ambulatory care pharmacists within a health-system in central Ohio. Interventions were collected within an electronic health record from January 1, 2020, to December 31, 2020. Cost savings were calculated using average wholesale pricing, and PA avoidance was quantified. RESULTS: A total of 278 alternative therapy interventions were made with an estimated cost savings of $133,191.43. Primary care clinics (n = 181, 65%) had the most documented interventions. A total of 174 (63%) interventions resulted in the avoidance of a PA. The antiallergen (28%) treatment category had the most documented interventions. CONCLUSIONS: Alternative therapy interventions were provided by pediatric ambulatory care pharmacists in collaboration with pharmacists working for an ACO. The use of ACO prescribing resources can result in cost savings to an ACO and PA avoidance within a pediatric Medicaid population.
