Increased self-reported pharmacist prescribing during the COVID-19 pandemic: Using the Theoretical Domains Framework to identify barriers and facilitators to prescribing

BACKGROUND: Community pharmacists are positioned to improve access to medications through their ever-expanding role as prescribers, with this role becoming more pronounced during the COVID-19 pandemic. OBJECTIVES: Our research aimed to determine the extent of self-reported pharmacist prescribing pre-COVID-19 and during the COVID-19 pandemic, to identify barriers and facilitators to pharmacist prescribing, and to explore the relationship between these factors and self-reported prescribing activity. METHODS: A questionnaire based on the Theoretical Domains Framework (TDFv2) assessing self-reported prescribing was electronically distributed to all direct patient care pharmacists in NS (N = 1338) in July 2020. Wilcoxon signed-rank tests were used to examine temporal differences in self-reported prescribing activity. TDFv2 responses were descriptively reported as positive (agree/strongly agree), neutral (uncertain), and negative (strongly disagree/disagree) based on the 5-point Likert scale assessing barriers and facilitators to prescribing from March 2020 onward (i.e., ‘during’ COVID-19). Simple logistic regression was used to measure the relationship between TDFv2 domain responses and self-reported prescribing activity. RESULTS: A total of 190 pharmacists (14.2%) completed the survey. Over 98% of respondents reported prescribing at least once per month in any of the approved prescribing categories, with renewals being the most common activity reported. Since the pandemic, activity in several categories of prescribing significantly increased, including diagnosis supported by protocol (29.0% vs. 58.9%, p < 0.01), minor and common ailments (25.3% vs 34.7%, p = 0.03), preventative medicine (22.1% vs. 33.2%, p < 0.01). Amongst the TDFv2 domains, Beliefs about Consequences domain had the largest influence on prescribing activity (OR = 3.13, 95% CI 1.41–6.97, p < 0.01), with Social Influences (OR = 2.85, 95% CI 1.42–5.70, p < 0.01) being the next most influential. CONCLUSION: Self-reported prescribing by direct patient care community pharmacists in Nova Scotia increased during the COVID-19 pandemic, particularly for government-funded services. Key barriers to address, and facilitators to support pharmacist prescribing were identified and can be used to inform future interventions.
