目的:探讨减少医院门诊处方药品用法用量不适宜的方法。方法:通过在HIS系统中增加药品合理用药数据如一次剂量、一次剂量单位、使用频率,来控制合理用药,分析控制前后平均每月门诊处方药品超剂量占比和超剂量药品品规数。结果:与控制前相比,控制后平均每月门诊处方药品超剂量占比明显降低(P=0.001),超剂量药品品规数减少(P=0.000)。结论:在医生开立处方时提示医生合理用药数据,可显著减少门诊不合适处方数量。

OBJECTIVE To investigate a method to reduce inappropriate drug usage in hospital outpatient prescriptions.METHODS The rational uses of drugs were added in HIS system, including single dose, unit, frequency, to control rational medication, analyze overdose prescription percentage and kinds and strengths of overdose drugs per average month before and after control.RESULTS Compared with those before control, percentage of drug overdose and kinds and strengths of overdose drugs were reduced (P=0.001, P=0.000, respectively) after control.CONCLUSION After the control, rate of inappropriate prescriptions is lowered.
