目的：了解影响居民自我药疗行为的主要外部影响因素，从而有针对性地促进居民合理用药。方法：采用问卷调查法对武汉市城区居民的自我药疗行为进行分层随机抽样调查。结果与结论：药品品牌是居民自我药疗过程中购药的首要影响因素（67．71％），药品说明书（84．57％）是用药过程的首要影响因素，而在获取药品信息方面对居民影响最大的还是医师和药师（54．00％）；医疗保险与购药金额和种类的关联性没有统计学意义（P〉0．05），与购药量、选择药品时考虑“医保”药品的关联性有统计学意义（P〈0．05）；城区差别与购药金额的关联性没有统计学意义（P〉0．05），与购药量、购药种类的关联性有统计学意义（P〈0．05）。应通过加强对药店、药品说明书和媒体广告的管理，加快城市社区建设，促进居民合理用药。
