Public health services and systems research (PHSSR) is the field of study charged with evaluating the public health system. PHSSR currently lacks a clear identity integrating the many theories, approaches, and disciplines contributing to the field.
Experts in PHSSR were consulted to identify 11 key published PHSSR studies. With these articles as a starting point, a newly developed citation data collection system was used to collect a sample of 2986 documents connected to the key articles through citation linkages. Data were collected in October 2009.
Citation network methods and latent position cluster modeling were used to examine the network of documents. A subset of 108 documents comprising the backbone of the network was identified through main-path analysis. Four unique clusters were identified within the main path. The core cluster consisted of older articles focused on local health department activities, partnerships, and effectiveness. The three non-core clusters focused on public health law, behavioral interventions, and national performance standards. Although all non-core clusters cited the core, there was little crosstalk among the non-core clusters, a pattern consistent with multidisciplinary fields.
PHSSR appears to be a multidisciplinary field with research happening in silos across different research areas. Developing transdisciplinary research connections across PHSSR is necessary to meet national PHSSR goals.
公共卫生服务与系统研究（PHSSR）是负责评估公共卫生系统的研究领域。PHSSR 目前缺乏一个明确的身份，无法将众多有助于该领域发展的理论、方法和学科整合在一起。
咨询 PHSSR 专家，确定了 11 项关键的已发表 PHSSR 研究。以此为起点，使用新开发的引文数据收集系统，通过引文链接收集了与关键文章相关的 2986 篇文献样本。数据于 2009 年 10 月收集。
使用引文网络方法和潜在位置聚类模型来研究文献网络。通过主路径分析，确定了网络的一个由 108 篇文献组成的子集，作为网络的主干。在主路径内识别出四个独特的聚类。核心聚类由关注地方卫生部门活动、伙伴关系和有效性的较旧文章组成。三个非核心聚类集中在公共卫生法、行为干预和国家绩效标准上。尽管所有非核心聚类都引用了核心聚类，但非核心聚类之间几乎没有交流，这种模式与多学科领域一致。
PHSSR 似乎是一个多学科领域，研究在不同研究领域的孤岛中进行。在 PHSSR 中发展跨学科研究联系对于实现国家 PHSSR 目标是必要的。
