背景：关于临床医生使用草药和膳食补充剂（HDS）的情况，他们个人使用HDS的情况如何随时间和培训而变化，以及他们个人使用HDS的变化如何影响他们对HDS的信心或与患者的沟通，我们知之甚少。方法：我们在2005年冬春进行了一项前瞻性队列研究，对临床医生进行了HDS在线课程前后的研究。结果：569名临床医生在基线和课程结束后完成了调查，25%为男性，平均年龄为42岁；88%的患者在课程前后使用HDS。平均服用补品的次数从基线时的6.2次略微下降到课程结束后的5.8次（P < 0.01）。基线时最常用的补充剂是：复合维生素（65%）、钙（42%）、B族维生素（34%）、维生素C（34%）、绿茶（27%）、鱼油（27%）和维生素E（25%）。疗程结束后鱼油的使用率增加到30% （P = 0.01）。传统上用于治疗感冒的补充剂的使用减少了：维生素C（34%至27%）、锌（13%至10%）和紫锥菊（7%至5%，三者均P < 0.05）。个人HDS使用的改变与信心或与患者沟通的显著变化无关。结论：许多临床医生亲自使用HDS；使用随季节而变化，在很小程度上与专业教育有关。HDS的专业使用是动态的和季节性的。需要进一步的研究来了解个人使用对HDS基线使用率较低人群的专业态度和行为的影响。
BACKGROUND: Little is known about clinicians' use of herbs and dietary supplements (HDS), how their personal HDS use changes with time and training, and how changes in their personal use affect their confidence or communication with patients about HDS.METHODS: We conducted a prospective cohort study of clinicians before and after an on-line curriculum about HDS in winter-spring, 2005.RESULTS: Of the 569 clinicians who completed surveys both at baseline and after the course, 25% were male and the average age was 42 years old; 88% used HDS before and after the course. The average number of supplements used fell slightly from 6.2 at baseline to 5.8 after the course (P < 0.01). The most commonly used supplements at baseline were: multivitamins (65%), calcium (42%), B vitamins (34%), vitamin C (34%), green tea (27%), fish oil (27%) and vitamin E (25%). Use of fish oil increased to 30% after the course (P = 0.01). Use of supplements traditionally used to treat colds decreased: vitamin C (34% to 27%), zinc (13% to 10%), and echinacea (7% to 5%, P < 0.05 for all three). Changes in personal HDS use were not associated with significant changes in confidence or communication with patients.CONCLUSION: Many clinicians use HDS personally; use changes seasonally and to a small extent with professional education. Professional use of HDS is dynamic and seasonal. Additional research is needed to understand the impact of personal use on professional attitudes and behavior in populations with lower baseline uses of HDS.
