The aim of this project was to evaluate the perceptions, knowledge and attitudes regarding generic medicines.
A cross-sectional study, with self administered questionnaires, was conducted to survey consumers visiting pharmacies in four regions of Auckland (North Shore, Waitakere, Central Auckland and South Auckland). Through stratified random sampling, approximately 10% of pharmacies from each region were selected, which turn out to be 30 pharmacies. Every alternate customer coming to the pharmacy, who was eligible to participate in the study, was asked by the researchers to complete the questionnaire.
A total of 441 questionnaires were included in the analysis. Different response rates were obtained in different regions of Auckland. Of all respondents, 51.6% had previous knowledge of generic medicines. Pharmacists were the main source of information regarding generic medicines followed by doctors and media. A higher level of education had a direct relationship with having correct knowledge of generics (P = .002). Attitude of participants toward the use of generic medicines was determined by their knowledge of generics, whether it was recommended by a pharmacist and their type of illness. Participants were more prepared to change to a generic for a minor illness (79%) than for a major illness (58.7%). Those who had better knowledge were more likely than those with poor knowledge to say they would to use a generic in major illness (P = .001) as well as minor illness (P < .0001). Previous positive experiences with generics also determined consumers' willingness to use generics.
Many consumers have misconceptions regarding generic medicines. Having knowledge about generics and the advice by doctors and pharmacists are key indicators to improve the quality use of generic medicines.
本项目旨在评估对仿制药的认知、知识和态度。
采用横断面研究,通过自填式问卷对奥克兰四个地区(北岸、怀塔克雷、奥克兰市中心和奥克兰南部)光顾药店的消费者进行调查。通过分层随机抽样,从每个地区选取约10%的药店,共30家药店。研究人员要求每一位符合参与研究条件、进入药店的交替顾客填写问卷。
共有441份问卷纳入分析。奥克兰不同地区的回复率不同。在所有受访者中,51.6%曾了解过仿制药。药剂师是关于仿制药信息的主要来源,其次是医生和媒体。较高的教育水平与对仿制药有正确认知直接相关(P = 0.002)。参与者对使用仿制药的态度取决于他们对仿制药的了解、是否由药剂师推荐以及他们的疾病类型。与重病(58.7%)相比,参与者更愿意在轻症时改用仿制药(79%)。知识掌握较好的人比知识掌握较差的人更有可能表示他们愿意在重病(P = 0.001)和轻症(P < 0.0001)时使用仿制药。之前使用仿制药的积极体验也决定了消费者使用仿制药的意愿。
许多消费者对仿制药存在误解。了解仿制药以及医生和药剂师的建议是提高仿制药合理使用的关键指标。
