Abstract

Purpose: To describe the practice settings and prescribing practices of oncology pharmacists with additional prescribing authorization. Methods: A descriptive, cross-sectional survey of all oncology pharmacists in Alberta was conducted using a web-based questionnaire over four weeks between March and April 2016. Pharmacists were identified from the Cancer Services Pharmacy Directory and leadership staff in Alberta Health Services. Descriptive statistics were used to describe the practice setting, prescribing practices, motivators to apply for additional prescribing authorization, and the facilitators and barriers of prescribing. Logistic regression was used to explore factors associated with having additional prescribing authorization. Results: The overall response rate was 41% (71 of 175 pharmacists). Oncology pharmacists with additional prescribing authorization made up 38% of respondents. They primarily worked in urban, tertiary cancer centers, and practiced in ambulatory care. The top 3 clinical activities they participated in were medication reconciliation, medication counseling/education, and ambulatory patient assessment. Respondents thought additional prescribing authorization was most useful for ambulatory patient assessment and follow-up. Antiemetics were prescribed the most often. The median number of prescriptions written in an average week of clinical work was 5. Competence, self-confidence, and the potential impact on patient care/perceived impact on work environment were the strongest facilitators of prescribing. The strongest motivators to apply for additional prescribing authorization were relevancy to practice, the potential for increased efficiency, and advancing the profession. Conclusion: The current majority of oncology pharmacist prescribing in Alberta occurs in ambulatory care with a large focus on antiemetic prescribing. Pharmacists found additional prescribing authorization most useful for ambulatory patient assessment and follow-up.
