While the past two decades have seen a shift towards evidence-based obstetrics and midwifery, the process through which a culture of evidence-based practice develops and is sustained within particular fields of clinical practice has not been well documented, particularly in LMICs (low- and middle-income countries). Forming part of a broader qualitative study of evidence-based policy making, this paper describes the development of a culture of evidence-based practice amongst maternal health policy makers and senior academic obstetricians in South Africa.
A qualitative case-study approach was used. 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.
The concept of evidence-based medicine became embedded in South African academic obstetrics at a very early stage in relation to the development of the concept internationally. The diffusion of this concept into local academic obstetrics was facilitated by contact and exchange between local academic obstetricians, opinion leaders in international research and structures promoting evidence-based practice. Furthermore the growing acceptance of the concept was stimulated locally through the use of existing professional networks and meetings to share ideas and the contribution of local researchers to building the evidence base for obstetrics both locally and internationally. As a testimony to the extent of the diffusion of evidence-based medicine, South Africa has strongly evidence-based policies for maternal health.
This case study shows that the combined efforts of local and international researchers can create a culture of evidence-based medicine within one country. It also shows that doing so required time and perseverance from international researchers combined with a readiness by local researchers to receive and actively promote the practice.
尽管过去二十年见证了向循证妇产科和助产实践的转变,但在特定临床实践领域中发展和维持循证实践文化的过程并未得到很好的记录,尤其是在中低收入国家(LMICs)。本文是对循证政策制定的更广泛定性研究的一部分,描述了南非孕产妇健康政策制定者和资深产科医生中循证实践文化的发展。
采用定性案例研究方法。这包括文献综述、政策文件审查、关键事件时间表以及对 15 名参与这些政策制定过程的政策制定者和学术临床医生的访谈的收集和分析,采用目的抽样方法进行抽样。数据进行了主题分析。
循证医学的概念在国际上发展的早期阶段就已经在南非学术产科中得到了深入的研究。通过当地学术产科医生、国际研究意见领袖以及促进循证实践的结构之间的联系和交流,将这一概念传播到当地学术产科。此外,通过利用现有的专业网络和会议来分享想法,以及当地研究人员为建立当地和国际产科的循证基础做出贡献,该概念在当地的接受程度不断提高。作为循证医学传播程度的证明,南非制定了非常循证的孕产妇健康政策。
本案例研究表明,当地和国际研究人员的共同努力可以在一个国家内创造循证医学文化。它还表明,要做到这一点,国际研究人员需要时间和毅力,同时还需要当地研究人员愿意接受并积极推广这一实践。
