The main challenges in international health are to scale up effective health interventions in low- and middle-income countries in order to reach a higher proportion of the population. This can be achieved through better insight into how health systems are structured. Social network analysis can provide an appropriate and innovative paradigm for the health systems researcher, allow new analyses of the structure of health systems, and facilitate understanding of the role of stakeholders within a health system. The social network analysis methodology adapted to health systems research and described in detail by the authors comprises three main stages: (i) describing the set of actors and members of the network; (ii) characterizing the relationships between actors; and (iii) analysing the structure of the systems. Evidence generated through social network analysis could help policy makers to understand how health systems react over time and to better adjust health programmes and innovations to the capacities of health systems in low- and middle-income countries to achieve universal coverage.
国际卫生的主要挑战是在中低收入国家扩大有效的卫生干预措施，以便覆盖更多的人口。这可以通过更好地了解卫生系统的结构来实现。社会网络分析可以为卫生系统研究人员提供一个合适和创新的范例，允许对卫生系统的结构进行新的分析，并有助于理解利益相关者在卫生系统中的作用。作者详细描述的适应卫生系统研究的社会网络分析方法包括三个主要阶段：(i)描述参与者和网络成员的集合；(ii)描述参与者之间的关系；(iii)分析系统的结构。通过社会网络分析产生的证据可以帮助决策者了解卫生系统如何随着时间的推移做出反应，并更好地调整卫生方案和创新，以适应中低收入国家卫生系统的能力，实现全民覆盖。
