To illustrate and to discuss some ethical challenges encountered during pharmacoepidemiological research in a developing country (Colombia), as well as the decisions made to solve them.
The authors in Bogotá describe three recent studies. The first one collected data from clinical records to evaluate the prescriptions patterns in recently graduated physicians. The second used an interrupted time series design, with a set of observations prior and after a combined intervention, to assess whether it improved the quality of intravenous antibiotic prescribing practices in a university-based hospital. The third evaluated pharmacists' advice in childhood acute respiratory infection and acute diarrhea through a community survey, followed by focus groups and in-depth interviews of key informers.
The ethical issues raised by these studies include the need for obtaining informed consent from participants (physicians in Study 1 and drug sellers in Study 3), deciding when to intervene in case of gross prescription mistakes detected during the collection of data as part of the time series assessment (Study 2), the use of simulated clients to collect data in the community survey, and the use of study resources to buy, in some cases, useless medications (Study 3).
Although ethical challenges in pharmacoepidemiology in non-industrialized countries like Colombia may be different from those in developed nations, ethical principles that guide research remain the same. The processes to safeguard these principles in Colombia for virtually all research are also universal in nature, and include the ethical review committee, subject privacy, informed consent, and disclosure of funding sources.
阐述并讨论在一个发展中国家(哥伦比亚)进行药物流行病学研究时遇到的一些伦理挑战,以及为解决这些挑战所做出的决策。
波哥大的作者描述了三项近期研究。第一项研究从临床记录中收集数据,以评估刚毕业医生的处方模式。第二项研究采用中断时间序列设计,在联合干预前后进行一系列观察,以评估其是否改善了一家大学医院静脉用抗生素处方行为的质量。第三项研究通过社区调查、焦点小组以及对关键信息提供者的深入访谈,评估药剂师对儿童急性呼吸道感染和急性腹泻的建议。
这些研究引发的伦理问题包括需要获得参与者(研究1中的医生和研究3中的药品销售商)的知情同意,在作为时间序列评估一部分的数据收集过程中发现严重处方错误时决定何时进行干预(研究2),在社区调查中使用模拟客户收集数据,以及在某些情况下使用研究资源购买无用药物(研究3)。
尽管在像哥伦比亚这样的非工业化国家,药物流行病学中的伦理挑战可能与发达国家不同,但指导研究的伦理原则是相同的。在哥伦比亚,几乎所有研究中保障这些原则的程序本质上也是通用的,包括伦理审查委员会、受试者隐私、知情同意以及资金来源披露。
