Eighty anxious and eighty depressed patients were assigned randomly to receiving one of three versions of an information leaflet about their medication, or to receiving no leaflet at all. Mean medication errors were reduced from 15 to 4% by provision of suitably constructed leaflets. The results show the practical importance of informing patients about their medication and of paying attention to the difficulty level of any leaflets issued.
80名焦虑患者和80名抑郁患者被随机分配，分别接受三种关于其药物治疗的信息手册版本之一，或者根本不接受任何手册。通过提供精心编写的手册，平均用药错误率从15%降至4%。结果表明，告知患者其药物治疗情况以及关注所发放手册的难易程度具有实际重要性。
