Few empirical studies of research utilisation have been conducted in low and middle income countries. This paper explores how research information, in particular findings from randomised controlled trials and systematic reviews, informed policy making and clinical guideline development for the use of magnesium sulphate in the treatment of eclampsia and pre-eclampsia in South Africa.
A qualitative case-study approach was used to examine the policy process. This included a literature review, a policy document review, a timeline of key events and the collection and analysis of 15 interviews with policy makers and academic clinicians involved in these policy processes and sampled using a purposive approach. The data was analysed thematically and explored theoretically through the literature on agenda setting and the policy making process.
Prior to 1994 there was no national maternal care policy in South Africa. Consequently each tertiary level institution developed its own care guidelines and these recommended a range of approaches to the management of pre-eclampsia and eclampsia. The subsequent emergence of new national policies for maternal care, including for the treatment of pre-eclampsia and eclampsia, was informed by evidence from randomised controlled trials and systematic reviews. This outcome was influenced by a number of factors. The change to a democratic government in the mid 1990s, and the health reforms that followed, created opportunities for maternal health care policy development. The new government was open to academic involvement in policy making and recruited academics from local networks into key policy making positions in the National Department of Health. The local academic obstetric network, which placed high value on evidence-based practice, brought these values into the policy process and was also linked strongly to international evidence based medicine networks. Within this context of openness to policy development, local researchers acted as policy entrepreneurs, bringing attention to priority health issues, and to the use of research evidence in addressing these. This resulted in the new national maternity care guidelines being informed by evidence from randomised controlled trials and recommending explicitly the use of magnesium sulphate for the management of eclampsia.
Networks of researchers were important not only in using research information to shape policy but also in placing issues on the policy agenda. A policy context which created a window of opportunity for new research-informed policy development was also crucial.
在低收入和中等收入国家,针对研究成果应用的实证研究较少。本文探讨了研究信息,特别是随机对照试验和系统评价的结果,如何为南非硫酸镁治疗子痫和先兆子痫的政策制定及临床指南制定提供信息。
采用定性案例研究方法来审视政策过程。这包括文献综述、政策文件审查、关键事件时间线以及对参与这些政策过程的政策制定者和学术临床医生进行15次访谈的收集与分析,访谈采用目的抽样法。数据进行了主题分析,并通过议程设置和政策制定过程的文献进行了理论探讨。
1994年之前,南非没有国家孕产妇护理政策。因此,每个三级医疗机构都制定了自己的护理指南,这些指南推荐了一系列先兆子痫和子痫的管理方法。随后新的国家孕产妇护理政策的出现,包括先兆子痫和子痫的治疗政策,受到了随机对照试验和系统评价证据的影响。这一结果受到多种因素的影响。20世纪90年代中期向民主政府的转变以及随后的卫生改革,为孕产妇保健政策的制定创造了机会。新政府对学术界参与政策制定持开放态度,并从当地网络招募学者担任国家卫生部关键政策制定职位。当地学术产科网络高度重视循证实践,将这些价值观带入政策过程,并且还与国际循证医学网络紧密相连。在这种对政策发展持开放态度的背景下,当地研究人员充当了政策企业家,提请关注优先健康问题以及在解决这些问题时使用研究证据。这导致新的国家孕产妇护理指南以随机对照试验的证据为依据,并明确推荐使用硫酸镁治疗子痫。
研究人员网络不仅在利用研究信息塑造政策方面很重要,而且在将问题列入政策议程方面也很重要。为新研究导向的政策发展创造机会之窗的政策背景也至关重要。
