BACKGROUND Sustainability of evidence-based interventions (EBI) remains a challenge for public health community-based institutions. The conceptual definition of sustainment is not universally agreed upon by researchers and practitioners, and strategies utilized to facilitate sustainment of EBI are not consistently reported in published literature. Given these limitations in the field, a systematic review was conducted to summarize the existing evidence supporting discrete sustainment strategies for public health EBIs and facilitating and hindering factors of sustainment. METHODS We searched PsychINFO, Embase, ProQuest, PubMed, and Google Scholar. The initial search was run in March 2017 and an update was done in March 2019. Study eligibility criteria included (a) public health evidence-based interventions, (b) conducted in the community or community-based settings, and (c) reported outcomes related to EBI sustainment. Details characterizing the study setting, design, target population, and type of EBI sustained were extracted. RESULTS A total of 26 articles published from 2004 to 2019 were eligible for data extraction. Overall, the importance of sustainability was acknowledged across all of the studies. However, only seven studies presented a conceptual definition of sustainment explicitly within the text. Six of the included studies reported specific sustainment strategies that were used to facilitate the sustainment of EBI. Only three of the studies reported their activities related to sustainment by referencing a sustainment framework. Multiple facilitators (i.e., adaptation/alignment, funding) and barriers (i.e., limited funding, limited resources) were identified as influencing EBI sustainment. The majority (n = 20) of the studies were conducted in high-income countries. Studies from low-income countries were mostly naturalistic. All of the studies from low-income countries reported lack of funding as a hindrance to sustainment. IMPLICATION FOR DISSEMINATION AND IMPLEMENTATION RESEARCH Literature focused on sustainment of public health EBIs should present an explicit definition of the concept. Better reporting of the framework utilized, steps followed, and adaptations made to sustain the intervention might contribute to standardizing and developing the concept. Moreover, encouraging longitudinal dissemination and implementation (D&I) research especially in low-income countries might help strengthen D&I research capacity in public health settings.

循证干预可持续性策略：系统回顾。

背景技术基于证据的干预措施（EBI）的可持续性仍然是基于公共卫生社区机构的挑战。研究人员和从业人员并未普遍同意维持的概念性定义，而用于促进EBI维持的策略在出版的文献中也未得到一致的报道。鉴于该领域的这些局限性，我们进行了系统的综述，总结了现有证据，这些证据支持公共卫生EBI的离散维持策略以及促进和阻碍维持的因素。方法我们搜索了PsychINFO，Embase，ProQuest，PubMed和Google Scholar。初步搜索于2017年3月进行，更新于2019年3月完成。研究的资格标准包括（a）基于公共卫生证据的干预措施，（b）在社区或社区环境中进行，并且（c）报告与EBI维持有关的结果。提取了表征研究环境，设计，目标人群和持续EBI类型的详细信息。结果从2004年到2019年，共有26篇文章符合数据提取条件。总体而言，所有研究都承认可持续性的重要性。但是，只有七项研究在文本中明确提出了可持续性的概念定义。纳入的研究中有六项报告了用于促进EBI维持的特定维持策略。只有三项研究通过参考可持续性框架报告了其与可持续性有关的活动。多个推动者（即适应/调整，资金）和障碍（即资金有限，有限的资源）被认为是影响EBI持续性的因素。大多数研究（n = 20）是在高收入国家进行的。来自低收入国家的研究大多是自然主义的。来自低收入国家的所有研究均报告说，缺乏资金是维持可持续发展的障碍。传播和实施研究的意义着重于维持公共卫生EBI的文献应提出对该概念的明确定义。更好地报告所利用的框架，遵循的步骤以及为维持干预措施而进行的调整，可能有助于该概念的标准化和发展。此外，特别是在低收入国家，鼓励纵向传播和实施（D＆I）研究可能有助于增强公共卫生环境中D＆I研究的能力。
