Patient Preferences for Pharmacy Services: A Systematic Review of Studies Based on Discrete Choice Experiments

Background and objective: In recent years, the mission of pharmacists has evolved and the model of the caregiver-patient relationship has been challenged by a new patient-centered approach. A challenge to providing personalized care is the assessment of patient preferences. We aimed to systematically identify published discrete choice experiments related to patient preferences for pharmacy services and to assess the quality of the selected articles.

Methods: A systematic review of the literature was conducted in two databases (PubMed and Embase, until March 2023) according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. The quality of the selected articles was assessed according to the International Society for Pharmacoeconomics and Outcomes Research conjoint analysis checklist.

Results: Among the 421 articles identified, 16 published studies were included and analyzed. They were mostly published in pharmaceutical (n = 6), economic (n = 4), and public health (n = 4) journals. Only two articles concerned the field of hospital pharmacy. Only five presented the specific pharmacy service studied: filling of prescriptions, management of symptoms, treatment delivery, and components of pharmacist counseling. Five articles focused on pharmacy services related to a specific disease. None fully fulfilled the International Society for Pharmacoeconomics and Outcomes Research checklist, only partially fulfilled.

Conclusions: According to the identified studies, cost, time, logistics (organizational criteria), and pharmacists' courtesy and skills were consistently cited as factors influencing patient preferences for pharmacy services. The disclosure of patient preferences is a complex and under-researched topic, especially in the field of pharmacy, but interest is growing. As the mission of pharmacists evolves to bring them closer to patients, the better understanding of patient preferences in pharmacy services will allow for better targeting and better integration of patient profiles in patient management.
