We conducted a Web-based survey of approximately 40,000 Internet users on the purchase of over-the-counter (OTC) medications online in March 2009. The valid response rate was 97.8% and the number of responses was 39,208. The number of people who had purchased OTC medications online was 4,653 (11.9%), prescription medicines 792 (2.0%), and medical contact lenses 1,993 (5.1%). As a result of the multiple logistic regression analysis, independent variables with odds ratios (ORs) >1.5 were experience of purchasing prescription-only medicine online (OR=4.997, 95%CI=4.288-5.824), regular supplement use (OR=2.384, 95%CI=2.233-2.548), experience of purchasing colored contact lenses online (OR=2.206, 95%CI=1.632-2.983), no time to visit drugstores (OR=2.092, 95%CI=1.928-2.270), usage of Web sites of uncertain reliability (OR=1.992, 95%CI=1.857-2.137), and experience of purchasing therapeutic contact lenses online (OR=1.796, 95%CI=1.597-2.020). As some people have purchased prescription-only medicine or medical devices and had problems with drug information sources, the development of awareness of medical and pharmaceutical supplies and health and medical information literacy are key priorities to ensure safe OTC medication sales systems.
2009年3月，我们对约40000名互联网用户进行了一项关于在线购买非处方药（OTC）的网络调查。有效回复率为97.8%，回复数量为39208份。曾在线购买非处方药的人数为4653人（11.9%），购买处方药的有792人（2.0%），购买医用隐形眼镜的有1993人（5.1%）。多因素逻辑回归分析结果显示，比值比（OR）>1.5的自变量包括在线购买过仅凭处方销售药品的经历（OR=4.997，95%置信区间=4.288-5.824）、经常使用补充剂（OR=2.384，95%置信区间=2.233-2.548）、在线购买彩色隐形眼镜的经历（OR=2.206，95%置信区间=1.632-2.983）、没有时间去药店（OR=2.092，95%置信区间=1.928-2.270）、使用可靠性不确定的网站（OR=1.992，95%置信区间=1.857-2.137）以及在线购买治疗性隐形眼镜的经历（OR=1.796，95%置信区间=1.597-2.020）。由于一些人在购买仅凭处方销售的药品或医疗设备时遇到了药品信息来源方面的问题，提高对医疗用品和健康及医学信息素养的认识是确保非处方药安全销售系统的关键优先事项。
