摘　　要：目的:建立较为科学、合理的处方抽样调查方法。方法:收集2008年4月～2009年2月本院门诊处方资料,采用分层等比例及非等比例抽样调查法(各取200例),与分层全查法(10725例)的数据进行比较,并以处方评价指标中的针剂使用率计算样本量。结果与结论:分层等比例抽样与全查的调查值比较差别无统计学意义(P>0.05);以总体概率最低值估算最小样本量的调查值接近总体水平,故此法可作为医疗机构开展处方评价工作中抽样调查的基本方法。OBJECTIVE： To establish a scientific and rational sampling survey method for prescription evaluation. METHODS： Out-patient prescriptions were collected from Apr. 2008 to Feb. 2009 in order to compare data calculated by stratified proportional sampling and stratified non-proportional sampling （n=200） with data calculated by stratified all sampling （n= 10 725）. The signifi- cantly sample volume was calculated according to utilization ratio of injection as evaluation index. RESULTS ＆ CONCLUSIONS： No statistic difference was noted between stratified proportional sampling and stratified all sampling （P〉0.05）. Minimum total probability are used to predict minimum sample volume which is close to overall level. Above method can be used as basic method for sample survey in regular prescription evaluation.
