Beliefs about bioidentical hormone therapy: a cross-sectional survey of pharmacists
1Faculty of Pharmacy and Pharmaceutical Sciences, 3-171 Edmonton Clinic Health Academy (ECHA), University of Alberta, Edmonton, AB, Canada.
Objective:
The aim of this study was to assess pharmacists' beliefs about bioidentical hormone therapy (BHT) and to identify factors influencing these beliefs.
Study Design:
This was a cross-sectional survey of pharmacists. An email invitation to participate in the online survey was sent to a random sample of 2000 pharmacists in Alberta. The survey was accessible for a six-week period from May to July, 2011. A 54-item questionnaire was used to capture knowledge and beliefs about, and confidence in BHT. Summary statistics and multivariate regression were used for analyses.
Results:
Overall, 401 pharmacists completed the survey (response rate 20%). Respondents were mainly female (64%), above 30 years of age (81%) and in practice for more than 10 years (63%). Only 35% of respondents correctly classified BHT as including both compounding and commercial products. In regards to beliefs, 68% of respondents agreed that BHT is as effective as non-bioidentical hormones for vasomotor symptoms, while 60% agreed BHT had equal risk. Beliefs on estriol, progesterone, and saliva testing however, were more diverse with many "do not know" responses (40%). In multivariate analysis, pharmacists who worked in pharmacies that compounded BHT were more likely to believe in BHT safety (p<0.001), and have greater confidence with BHT (p<0.001).
Conclusions:
Results from this survey indicated that pharmacists had varying beliefs on BHT. In addition, beliefs on the safety of BHT were associated with pharmacists' practice, specifically working in a pharmacy that compounds BHT. This study helps identify areas for targeted education.

Species differences: Variations in enzyme systems across species can cause disparities in drug metabolism. For instance, humans may metabolize certain drugs faster than rodents, altering therapeutic effects.
Strain differences: Genetic variations within a species can result in differing enzyme activity, impacting drug response and toxicity. For example, some mouse strains may...
