Can Fam Physician. 1990 Mar;36:465-70.
General practitioners write the vast majority of the 190 million prescriptions issued annually in Canada. The author reviewed the English language literature to determine the general characteristics of that prescribing, the appropriateness of prescribing, and factors that influence prescribing. On average, GPs write one prescription for every two office visits. Each prescription is for 1.2 to 1.4 items. Most of any GP's prescriptions are for a group of fewer than 30 different medications. Factors that influence prescribing include generic prescribing and knowledge of drug contents, provincial drug programs, physician and patient characteristics, type of practice, source of information about drugs, and rapidity of adoption of new drugs. The author offers suggestions for improving prescribing.
全科医生开具了加拿大每年开出的 1.9 亿张处方中的绝大多数。作者查阅了英文文献，以确定这些处方的一般特征、开具处方的适当性以及影响处方的因素。平均而言，每位全科医生每次就诊开一张处方。每张处方开 1.2 到 1.4 种药物。任何全科医生处方中，大多数药物属于不到 30 种不同药物的一组。影响处方的因素包括通用处方和对药物成分、省级药物计划、医生和患者特征、实践类型、药物信息来源以及新药采用速度的了解。作者提出了改进处方的建议。
