To compare the use of dietary supplements and nonprescription medications as reported on a written medical questionnaire with use reported during a structured interview.
We conducted a prospective study of 200 subjects randomly selected among patients undergoing a periodic health examination in two divisions of the Department of Internal Medicine at Mayo Clinic Rochester--100 patients from a national cohort of executives and 100 community patients.
Written information on self-reported use of supplements and nonprescription medications was obtained as part of a comprehensive medical questionnaire. Subjects were then interviewed and asked about the use of supplements and nonprescription medications. In addition, the reason for using supplements was elicited and recorded.
The prevalence of use of dietary supplements was 30.5% by written self-report in comparison with 61.0% reported during the structured interview. The results were consistent between executive and community patients. In response to questions about taking nonprescription medications, 24.5% of patients reported such use on the medical questionnaire in comparison with 42.5% when interviewed. The most common dietary supplements taken were multivitamins (41.5%), followed by vitamin E (24.0%) and vitamin C (23.0%). The most common nonprescription medications taken were aspirin (16.5%) and ibuprofen (13.0%). Most frequently, patients indicated that they were using supplements to promote health.
In this study, half the patients who took dietary supplements and almost half who took nonprescription medications did not report them to their healthcare provider on a written questionnaire, even though this information was requested. Patients should be specifically asked about use of dietary supplements and nonprescription medications, even if written information about such use is provided.
比较书面医学问卷所报告的膳食补充剂和非处方药的使用情况与结构化访谈中所报告的使用情况。
我们对罗切斯特梅奥诊所内科两个科室中接受定期健康检查的患者随机抽取的200名受试者进行了一项前瞻性研究——100名来自全国高管队列的患者和100名社区患者。
作为一份综合医学问卷的一部分，获取了关于自我报告的补充剂和非处方药使用情况的书面信息。然后对受试者进行访谈，询问他们补充剂和非处方药的使用情况。此外，还引出并记录了使用补充剂的原因。
通过书面自我报告，膳食补充剂的使用 prevalence 为30.5%，而在结构化访谈中报告的为61.0%。高管患者和社区患者的结果一致。在回答关于服用非处方药的问题时，24.5%的患者在医学问卷中报告了此类使用情况，而访谈时为42.5%。最常服用的膳食补充剂是多种维生素（41.5%），其次是维生素E（24.0%）和维生素C（23.0%）。最常服用的非处方药是阿司匹林（16.5%）和布洛芬（13.0%）。患者最常表示他们使用补充剂是为了促进健康。
在本研究中，尽管问卷要求提供相关信息，但服用膳食补充剂的患者中有一半以及服用非处方药的患者中近一半在书面问卷中未向其医疗服务提供者报告。即使已提供关于此类使用情况的书面信息，也应特别询问患者关于膳食补充剂和非处方药的使用情况。
