BACKGROUND Integrated care is an increasingly important principle for organising healthcare. Integrated care models show promise in reducing resource wastage and service fragmentation whilst improving the accessibility, patient-centredness and quality of care for patients. Those needing reliable access to the growing research evidence base for integrated care can be frustrated by search challenges reflective of the topic's complexity. The aim of this study is to report the empirical development and validation of two search filters for rapid and effective retrieval of integrated care evidence in PubMed. One filter is optimised for recall and the other for precision. METHODS An Expert Advisory Group comprising international integrated care experts guided the study. A gold standard test set of citations was formed from screening Handbook Integrated Care chapter references for relevance. This set was divided into a Term Identification Set (20%) for determining candidate terms using frequency analysis; a Filter Development Set (40%) for testing performance of term combinations; and a Filter Validation Set (40%) reserved for confirming final filter performance. In developing the high recall filter, recall was steadily increased while maintaining precision at ≥50%. Similarly, the high precision filter sought to maximise precision while keeping recall ≥50%. For each term combination tested, an approximation of precision was obtained by reviewing the first 100 citations retrieved in Medline for relevance. RESULTS The gold standard set comprised 534 citations. The search filter optimised for recall ('Broad Integrated Care Search') achieved 86.0-88.3% recall with corresponding low precision (47-53%). The search filter optimised for precise searching ('Narrow Integrated Care Search') demonstrated precision of 73-95% with recall reduced to between 55.9 and 59.8%. These filters are now available as one-click URL hyperlinks in the website of International Foundation for Integrated Care. CONCLUSIONS The Broad and Narrow Integrated Care Search filters provide potential users, such as policy makers and researchers, seamless, reliable and ongoing access to integrated care evidence for decision making. These filters were developed according to a rigorous and transparent methodology designed to circumvent the challenges of information retrieval posed by this complex, multifaceted topic.

综合护理搜索:开发和验证PubMed搜索过滤器,以检索综合护理研究证据。

背景技术综合护理是组织医疗保健的越来越重要的原则。综合护理模型显示出有望减少资源浪费和服务分散化,同时改善患者的可及性,以患者为中心和护理质量。那些需要可靠地获取不断增长的综合护理研究证据库的人可能会因反映该主题复杂性的搜索挑战而沮丧。这项研究的目的是报告两个搜索过滤器的经验发展和验证,以快速有效地检索PubMed中的综合护理证据。一种过滤器针对召回进行了优化,另一种针对精度进行了优化。方法由国际综合护理专家组成的专家咨询小组对研究进行了指导。通过筛选《手册》中的“相关内容”,形成了金标准的引文测试集。将该集合分为术语识别集(20%),以便使用频率分析确定候选术语。过滤器开发套件(占40%),用于测试术语组合的效果;并保留了一个过滤器验证集(40%)以确认最终的过滤器性能。在开发高召回率滤波器时,召回率稳步提高,同时保持≥50%的精度。同样,高精度过滤器试图在保持召回率≥50%的同时最大化精度。对于每个测试的术语组合,通过查看Medline中相关的前100个引文,可以得出精确度的近似值。结果黄金标准集包含534个引用。针对召回进行了优化的搜索过滤器(“ 广泛综合护理搜索()的召回率达到86.0-88.3%,相应的准确性较低(47-53%)。针对精确搜索(“ Narrow Integrated Care Search”)进行了优化的搜索过滤器显示出73-95%的精度,召回率降至55.9至59.8%之间。现在,这些过滤器可以作为一键式URL超链接在国际综合护理基金会的网站上使用。结论广泛和狭窄的综合护理搜索过滤器为潜在的用户(例如决策者和研究人员)提供了无缝,可靠和持续的综合护理证据,以供决策使用。这些过滤器是根据严格而透明的方法开发的,旨在避免由这个复杂,多面的主题带来的信息检索挑战。3%的召回率和相应的低精度(47-53%)。针对精确搜索(“ Narrow Integrated Care Search”)进行优化的搜索过滤器显示出73-95%的精度,召回率降至55.9至59.8%之间。现在,这些过滤器可以作为一键式URL超链接在国际综合护理基金会的网站上使用。结论广泛和狭窄的综合护理搜索过滤器为潜在的用户(例如决策者和研究人员)提供了无缝,可靠和持续的综合护理证据,以供决策使用。这些过滤器是根据严格而透明的方法开发的,旨在避免由这个复杂,多面的主题带来的信息检索挑战。3%的召回率和相应的低精度(47-53%)。针对精确搜索(“ Narrow Integrated Care Search”)进行了优化的搜索过滤器显示出73-95%的精度,召回率降至55.9至59.8%之间。现在,这些过滤器可以作为一键式URL超链接在国际综合护理基金会的网站上使用。结论广泛和狭窄的综合护理搜索过滤器为潜在的用户(例如决策者和研究人员)提供了无缝,可靠和持续的综合护理证据,以供决策使用。这些过滤器是根据严格而透明的方法开发的,旨在避免由这个复杂,多面的主题带来的信息检索挑战。Narrow Integrated Care Search')的准确度为73-95%,召回率降至55.9至59.8%之间。现在,这些过滤器可以作为一键式URL超链接在国际综合护理基金会的网站上使用。结论广泛和狭窄的综合护理搜索过滤器为潜在的用户(例如决策者和研究人员)提供了无缝,可靠和持续的综合护理证据,以供决策使用。这些过滤器是根据严格而透明的方法开发的,旨在避免由这个复杂,多面的主题带来的信息检索挑战。Narrow Integrated Care Search')的准确度为73-95%,召回率降至55.9至59.8%之间。现在,这些过滤器可以作为一键式URL超链接在国际综合护理基金会的网站上使用。结论广泛和狭窄的综合护理搜索过滤器为潜在的用户(例如决策者和研究人员)提供了无缝,可靠和持续的综合护理证据,以供决策使用。这些过滤器是根据严格而透明的方法开发的,旨在避免由这个复杂,多面的主题带来的信息检索挑战。现在,这些过滤器可以作为一键式URL超链接在国际综合护理基金会的网站上使用。结论广泛和狭窄的综合护理搜索过滤器为潜在的用户(例如决策者和研究人员)提供了无缝,可靠和持续的综合护理证据,以供决策使用。这些过滤器是根据严格而透明的方法开发的,旨在避免由这个复杂,多面的主题带来的信息检索挑战。现在,这些过滤器可以作为一键式URL超链接在国际综合护理基金会的网站上使用。结论广泛和狭窄的综合护理搜索过滤器为潜在的用户(例如决策者和研究人员)提供了无缝,可靠和持续的综合护理证据,以供决策使用。这些过滤器是根据严格而透明的方法开发的,旨在避免由这个复杂,多面的主题带来的信息检索挑战。
