ABSTRACT
INTRODUCTION: Community pharmacies currently offer Medicare Part D consultation services, often at no-cost. Despite facilitating plan-switching behavior, identifying potential cost-savings, and increasing medication adherence, patient uptake of these services remains low. OBJECTIVES: To investigate patient preferences for specific service-offering attributes and marginal willingness-to-pay (mWTP) for an enhanced community pharmacy Medicare Part D consultation service. METHODS: A discrete choice experiment (DCE) guided by the SERVQUAL framework was developed and administered using a national online survey panel. Study participants were English-speaking adults (≥65 years) residing in the United States enrolled in a Medicare Part D or Medicare Advantage plan and had filled a prescription at a community pharmacy within the last 12 months. An orthogonal design resulted in 120 paired-choice tasks distributed equally across 10 survey blocks. Data were analyzed using mixed logit and latent class models. RESULTS: In total, 540 responses were collected, with the average age of respondents being 71 years. The majority of respondents were females (60%) and reported taking four or more prescription medication (51%). Service attribute levels with the highest utility were: 15-min intervention duration (0.392), discussion of services + a follow-up phone call (0.069), in-person at the pharmacy (0.328), provided by a pharmacist the patient knew (0.578), and no-cost (3.382). The attribute with the largest mWTP value was a service provided by a pharmacist the participant knew ($8.42). Latent class analysis revealed that patient preferences for service attributes significantly differed by gender and difficulty affording prescription medications. CONCLUSIONS: Quantifying patient preference using discrete choice methodology provides pharmacies with information needed to design service offerings that balance patient preference and sustainability. Pharmacies may consider providing interventions at no-cost to subsets of patients placing high importance on a service cost attribute. Further, patient preference for 15-min interventions may inform Medicare Part D service delivery and facilitate service sustainability.
