The evidence base developed by, and relevant to, primary health care (PHC) is rapidly increasing. With the wealth of literature available, searchers trying to find PHC-specific citations can feel overwhelmed.
Flinders Filters and the Primary Health Care Research & Information Service collaborated to develop a search filter enabling efficient and effective retrieval of relevant PHC literature.
Stage 1 involved developing a PHC Search Filter in the OvidSP Medline platform using a rigorous experimental methodology. The search filter was then translated for Web-based 'one-click searching' in PubMed during Stage 2. Stage 3 involved planning and implementing a mixed-methods evaluation.
The search filter sensitivity was 77.0% with a post hoc relevance assessment of 78.3%. Four months after its launch, a mixed-methods study evaluated the PHC Search Filter. With 90 respondents, analysis of data from the online survey demonstrated overarching benefits, a positive response to the tool and directions for further refinement of the PHC Search Filter.
Designing the PHC Search Filter followed an established method that ensures the tool offers a validated search strategy. Evaluation results suggest that the PHC Search Filter is a useful tool that is easy to navigate. Challenges for the Filter relate to access to full text articles, while challenges for the evaluation relate to the small sample size.
The PHC Search Filter reduces the burden associated with literature searching, increases the value of the results that are received and provides a useful resource to improve the likelihood of incorporating relevant evidence into policy and practice.
由初级卫生保健（PHC）产生并与之相关的证据基础正在迅速增加。面对大量可得的文献，试图查找特定于初级卫生保健的文献引用的检索者可能会感到不知所措。
弗林德斯筛选器（Flinders Filters）与初级卫生保健研究与信息服务中心合作开发一种检索筛选器，以高效且有效地检索相关的初级卫生保健文献。
第一阶段涉及在OvidSP Medline平台上使用严格的实验方法开发初级卫生保健检索筛选器。然后在第二阶段将该检索筛选器进行翻译，以便在PubMed中进行基于网络的“一键式检索”。第三阶段涉及规划和实施一项混合方法评估。
检索筛选器的敏感度为77.0%，事后相关性评估为78.3%。在其推出四个月后，一项混合方法研究对初级卫生保健检索筛选器进行了评估。90名受访者参与，对在线调查数据的分析表明了总体益处、对该工具的积极反馈以及初级卫生保健检索筛选器进一步完善的方向。
设计初级卫生保健检索筛选器遵循了既定方法，确保该工具提供经过验证的检索策略。评估结果表明，初级卫生保健检索筛选器是一个易于使用的有用工具。该筛选器面临的挑战与获取全文文章有关，而评估面临的挑战与样本量小有关。
初级卫生保健检索筛选器减轻了与文献检索相关的负担，提高了所获结果的价值，并提供了一个有用资源，以增加将相关证据纳入政策和实践的可能性。
