A prototype for evidence-based pharmaceutical opinions to promote physician-pharmacist communication around deprescribing

Abstract

Context: Interprofessional communication is an effective mechanism for reducing inappropriate prescriptions among older adults. Physicians' views about which elements are essential for pharmacists to include in an evidence-based pharmaceutical opinion for deprescribing remain unknown.

Objective: To develop a prototype for an evidence-based pharmaceutical opinion that promotes physician-pharmacist communication around deprescribing.

Methods: A standardized template for an evidence-based pharmaceutical opinion was developed with input from a convenience sample of 32 primary care physicians and 61 primary care pharmacists, recruited from conferences and community settings in Montreal, Canada. Participants were asked to comment on the need for clarifying treatment goals, including personalized patient data and biomarkers, highlighting evidence about drug harms, listing the credibility and source of the recommendations, providing therapeutic alternatives and formalizing official documentation of decision making. The content and format of the prototype underwent revision by community physicians and pharmacists until consensus was reached on a final recommended template.

Results: The majority of physicians (84%-97%) requested that the source of the deprescribing recommendations be cited, that alternative management options be provided and that the information be tailored to the patient. Sixteen percent of physicians expressed concern about the information in the opinions being too dense. Pharmacists also questioned the length of the opinion and asked that additional space be provided for the physician's response. A statement was added making the opinion a valid prescription upon receipt of a signature from physicians. Compared to a nonstandardized opinion, the majority of pharmacists believed the template was easier to use, more evidence based, more time efficient and more likely to lead to deprescribing.

Conclusion: Physicians and pharmacists endorsed a standardized template that promotes interprofessional communication for deprescribing (available at https://www.deprescribingnetwork.ca/pharmaceutical-opinions). The outcome of the D-Prescribe trial will determine the effectiveness of these evidence-based pharmaceutical opinions on deprescribing processes and outcomes. Can Pharm J (Ott) 2018;151:xx-xx.
