Reports of regulatory and evidentiary gaps have raised concerns about the marketing and use of natural health products (NHPs). The majority of NHPs offered for sale are purchased at a community pharmacy and pharmacists are "front-line" health professionals involved in the marketing and provision of NHPs. To date, the involvement of pharmacists in pharmacy care involving NHPs and the degree to which concerns over the safety, efficacy, marketing and regulation of NHPs are addressed in pharmacy care in Canada have not been studied.
Using Qualtrics, a web-based data collection and analysis software, and a study instrument made up of fifteen (15) open-ended, closed and rating scale questions, we surveyed the attitudes and practices of 403 community pharmacists in the Canadian province of Alberta regarding NHPs offered for sale in community pharmacies.
The majority of pharmacists surveyed (276; 68%) recommend NHPs to clients sometimes to very often. Vitamin D, calcium, multivitamins, prenatal vitamins, probiotics and fish oil and omega-3 fatty acids were the most frequently recommended NHPs. The most common indications for which NHPs are recommended include bone and musculoskeletal disorders, maintenance of general health, gastrointestinal disorders and pregnancy. Review articles published in the Pharmacist's Letter and Canadian Pharmacists Journal were the primary basis for recommending NHPs. The majority of pharmacists surveyed (339; 84%) recommend the use of NHPs concurrently with conventional drugs, while a significant number and proportion (125; 31%) recommend alternative use. Pharmacists in the study overwhelmingly reported providing counselling on NHPs to clients based on information obtained mainly from the Natural Medicines Comprehensive Database.
The study findings indicate a high prevalence of pharmacy care relating to NHPs among study participants. Although pharmacists' practices around NHPs are consistent with the existing licensing framework, we found some involvement in problematic practices that necessitate further research and potential policy scrutiny. The study also uncovered patterns of recommendations, including sources relied on in recommending NHPs and in providing counselling to patients, that raise concerns about the quality and credibility of NHP-related care provided to pharmacy patrons.
关于监管和证据差距的报告引发了对天然健康产品(NHPs)营销和使用的担忧。大多数待售的天然健康产品是在社区药房购买的,药剂师是参与天然健康产品营销和供应的“一线”健康专业人员。迄今为止,加拿大药剂师在涉及天然健康产品的药房护理中的参与情况,以及在药房护理中对天然健康产品的安全性、有效性、营销和监管的关注程度尚未得到研究。
我们使用基于网络的数据收集和分析软件Qualtrics以及由15个开放式、封闭式和评分量表问题组成的研究工具,对加拿大艾伯塔省的403名社区药剂师关于社区药房待售天然健康产品的态度和做法进行了调查。
大多数接受调查的药剂师(276人;68%)有时至经常向客户推荐天然健康产品。维生素D、钙、多种维生素、产前维生素、益生菌以及鱼油和ω-3脂肪酸是最常被推荐的天然健康产品。推荐天然健康产品的最常见适应症包括骨骼和肌肉骨骼疾病、维持整体健康、胃肠道疾病和怀孕。发表在《药剂师通讯》和《加拿大药剂师杂志》上的综述文章是推荐天然健康产品的主要依据。大多数接受调查的药剂师(339人;84%)推荐同时使用天然健康产品和传统药物,而相当数量和比例(125人;31%)推荐交替使用。参与研究的药剂师绝大多数报告称,主要根据从《天然药物综合数据库》获得的信息为客户提供有关天然健康产品的咨询。
研究结果表明,研究参与者中与天然健康产品相关的药房护理普遍存在。尽管药剂师围绕天然健康产品的做法与现有的许可框架一致,但我们发现他们参与了一些有问题的做法,这需要进一步研究和潜在的政策审查。该研究还揭示了推荐模式,包括推荐天然健康产品和为患者提供咨询时所依赖的来源,这引发了对向药房顾客提供的与天然健康产品相关护理的质量和可信度的担忧。
