文摘目的评价实施临床路径(clinical pathway,CP)的急性ST段抬高心肌梗死(ST elevated myocardial infarction,STEMI)患者的用药情况及合理性。方法收集和整理安徽省淮南市朝阳医院2018年1月1日至2019年12月31日实施CP的STEMI患者相关资料,采用药物利用评价(drug use review,DUR)和药物利用评估法(drug use evaluation,DUE),对STEMI临床路径患者的药物利用指数、评价指标和诊断、治疗药物监测及临床诊疗效果进行综合分析。结果76例患者所用主要治疗药物共38种,其中5种药物利用指数(drug utilization index,DUI)>1,20种药物DUI<1,13种药物DUI=1。用药强度居前列的药物为阿司匹林肠溶片、硫酸氢氯吡格雷片、阿托伐他汀钙片、替格瑞洛片、泮托拉唑肠溶片、单硝酸异山梨酯片和盐酸曲美他嗪片。76例患者入院后均首次接受了心肌损伤标志、肝功能、肾功能、血常规及血脂水平等指标的监测;治疗期间再次接受心肌损伤标志、肝功能、肾功能、血常规和血脂水平的监测及异常再监测的比例分别为100.00%、40.78%、22.36%、9.21%和3.94%。药品不良反应(adverse drug reaction,ADR)共发生9例次。经过治疗后,76例(100.00%)患者临床症状明显好转。结论联合应用DUR和DUE可全面评估实施CP的STEMI患者的用药情况,及时发现不合理用药情况,促进临床药物合理使用。
