The evidence base for improving reproductive health continues to grow. However, concerns remain that the translation of this evidence into appropriate policies is partial and slow. Little is known about the factors affecting the use of evidence by policy makers and clinicians, particularly in developing countries. The objective of this study was to examine the factors that might affect the translation of randomised controlled trial (RCT) findings into policies and practice in developing countries.
The recent publication of an important RCT on the use of magnesium sulphate to treat pre-eclampsia provided an opportunity to explore how research findings might be translated into policy. A range of research methods, including a survey, group interview and observations with RCT collaborators and a survey of WHO drug information officers, regulatory officials and obstetricians in 12 countries, were undertaken to identify barriers and facilitators to knowledge translation.
It proved difficult to obtain reliable data regarding the availability and use of commonly used drugs in many countries. The perceived barriers to implementing RCT findings regarding the use of magnesium sulphate for pre-eclampsia include drug licensing and availability; inadequate and poorly implemented clinical guidelines; and lack of political support for policy change. However, there were significant regional and national differences in the importance of specific barriers.
The policy changes needed to ensure widespread availability and use of magnesium sulphate are variable and complex. Difficulties in obtaining information on availability and use are combined with the wide range of barriers across settings, including a lack of support from policy makers. This makes it difficult to envisage any single intervention strategy that might be used to promote the uptake of research findings on magnesium sulphate into policy across the study settings. The publication of important trials may therefore not have the impacts on health care that researchers hope for.
改善生殖健康的证据基础在不断扩大。然而,人们仍然担心这些证据转化为适当政策的过程并不全面且进展缓慢。对于影响政策制定者和临床医生使用证据的因素,尤其是在发展中国家,人们了解甚少。本研究的目的是探讨可能影响将随机对照试验(RCT)结果转化为发展中国家政策和实践的因素。
最近发表的一项关于使用硫酸镁治疗先兆子痫的重要随机对照试验提供了一个机会,来探索研究结果如何转化为政策。采用了一系列研究方法,包括对随机对照试验合作者进行调查、小组访谈和观察,以及对12个国家的世界卫生组织药物信息官员、监管官员和产科医生进行调查,以确定知识转化的障碍和促进因素。
事实证明,在许多国家很难获得关于常用药物的可得性和使用情况的可靠数据。在将关于使用硫酸镁治疗先兆子痫的随机对照试验结果付诸实施方面,人们认为存在的障碍包括药物许可和可得性;临床指南不完善且执行不力;以及缺乏对政策变革的政治支持。然而,具体障碍的重要性在地区和国家之间存在显著差异。
确保硫酸镁广泛可得和使用所需的政策变化是多样且复杂的。获取可得性和使用信息的困难,再加上不同环境中存在的各种障碍,包括政策制定者缺乏支持,这使得很难设想任何单一的干预策略可用于促进在所有研究环境中将关于硫酸镁的研究结果纳入政策。因此,重要试验的发表可能不会产生研究人员所期望的对医疗保健的影响。
