Assessment of the implementation of pharmacist prescribing: Challenges and pathways for ambulatory practice.

Background: Prescribing by pharmacists is an increasingly common practice worldwide. In Brazil regulation of this practice began in 2013, and the practice remains unexplored as a research topic.

Objective: We aimed to explore and gain insights into pharmacist prescribing practices in Brazil and assessing pharmacist's perceptions of their training and preparedness to prescribe medications.

Methods: A cross-sectional survey was conducted between October 2022 and March 2023 via convenience sampling. Data were collected using an online questionnaire covering sociodemographic issues, academic training, prescribing practices, and perceptions regarding the provision of pharmacist prescribing in ambulatory care. Exploratory descriptive analysis and Poisson regression were performed to estimate the associations between pharmacist characteristics and their practices in prescribing medicines.

Results: Among the 305 valid responses, 58.7% of the outpatient pharmacists stated that they had not prescribed any medication in the previous three years. Over-the-counter medication prescriptions were most common (42.0%). Only 4.6% of respondents had prescribed prescription-only medicines provided through collaborative agreement, with 2.6% reporting that they had adjusted doses, and 2.3% played a role in prescription renewal. Pharmacists living in Northeast regions tended to be more active prescribers (PR = 1.42; 95%CI 1.03-2.18), whereas those in primary healthcare (PR = 0.61; 95%CI 0.39-0.96) and self-declared Black pharmacists (PR = 0.30; 95%CI 0.10-0.97) prescribed less. Respondents strongly believed in the pharmacist's role as a prescriber, although they remained ambivalent regarding their responsibility for patient outcomes. Progress barriers include infrastructure gaps and strained relationships with physicians.

Conclusions: This study suggests that pharmacists in Brazil predominantly prescribe over-the-counter medications, and variations in setting, region, and race can influence prescribing by pharmacist in ambulatory care.
