用药错误已成为严重的公共卫生问题，老年患者是用药错误发生率最高的群体。老年患者发生用药错误的风险因素包括罹患疾病种类多、用药品种多（包括高警示药品）、肝肾功能减退、认知障碍和独居等。老年患者用药错误的常见类型包括漏服药物、未按规定时间服药、用药方法错误、因遗忘而重复用药、超剂量用药和误服禁止同时服用的药物等。临床医师和药师应共同参与老年患者的用药管理，医师开具处方时应加强与患者的沟通，药师应加强对处方的审核，以提高老年患者的用药依从性。建议采用口头与书面相结合的形式耐心地对老年患者进行用药教育，借助电子设备提醒老年患者用药，对记忆力明显减退的老年患者应求助其家属参与用药管理。“,”Medication errors have become a serious public health problem. Elderly patients have the highest incidence of medication errors. The risk factors of medication errors in elderly patients include suffering from more co-existing diseases, multiple drug use (including high-alert drugs), liver and kidney dysfunction, cognitive impairment, and living alone. The common types of medication errors in elderly patients include drug omission, failure to take medicine according to the scheduled time, wrong medication method, repeated medication due to forgetting, over dose medication, mistakenly taking drugs prohibited to be taken at the same time, and etc. Clinicians and pharmacists should participate in the medication management in the elderly patients together. Clinicians should strengthen communication with patients when prescribing prescriptions and pharmacists should strengthen the prescription review, so as to improve their medication compliance. It is suggested that medication education in the elderly patients should be patiently carried out with oral and written forms, electronic equipment could be used to help remind elderly patients of medication, and the family members of elderly patients with memory impairment should be asked to participate in the medication management.
