Attributes for a discrete-choice experiment on preferences of patients for oncology pharmacy consultations.

PURPOSE: To ensure the safe use of oral anticancer drugs, oncology pharmacy consultations (OPCs) have been established in France. They are conditioned by the needs, expectations, and involvement of the patients in their care. Thus, it is essential to elicit their preferences. The discrete-choice experiment (DCE) is a method recommended by the ISPOR for such a task. The "selection and validation of attributes and their values" step is fundamental in this process. In this context, the aim of this study was to present our research approach to identify and validate the attributes that characterize an OPC and their values. METHODS: Due to the lack of relevant published data in the literature, the focus-group method was used in accordance with good research practices for the application of conjoint-analysis of the ISPOR. The two-round Delphi method was used to validate the attributes and their values identified by the focus-group method. RESULTS: The focus-group method enabled identification of nine attributes. Thirty-seven healthcare professionals at a national level, including 30 pharmacists and seven physicians, were selected to take part in the Delphi procedure. Seven attributes (frequency, planification, operation mode, duration, content, written support, and report) and their values were thus validated. CONCLUSION: Based on these results, the next step will be to elicit patient preferences for OPCs and to then shed light on the issues of pharmaceutical support for patients by comparing their preferences with those of informal caregivers and, in particular, those of the healthcare professionals involved in their care.

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.
