目的：为了评估已发表的搜索过滤器在寻找诊断测试的准确性study.Methods：诊断测试的准确性搜索过滤器的性能确定通过搜索MEDLINE，我们自己的文件，并要求未发表的过滤器从同事。我们将过滤器应用于幼儿尿路感染（UTI）诊断测试准确性研究的病例研究综述。纳入的在MEDLINE中有记录的研究形成了金标准。评估了过滤器在查找这些金标准记录方面的性能。结果：我们确定了23个可与MEDLINE一起使用的诊断测试准确性搜索过滤器。UTI的病例研究系统综述包括179项诊断测试准确性的研究，其中160项可在MEDLINE中获得。过滤器表现出广泛的灵敏度（范围：20.6%至86.9%）和精度（范围：1%至9.4%）。结论：我们的研究结果广泛支持在其他两项研究中报道的。测试的检索过滤器没有提供用于识别系统评价研究的灵敏度和精确度之间的充分权衡。然而，有一些方法可以根据对记录中使用的文本和索引的客观统计分析来探索搜索过滤器是否可行。
Objectives: To assess the performance of published search filters in finding diagnostic test accuracy studies.Methods: Diagnostic test accuracy search filters were identified by searching MEDLINE, our own files and by requesting unpublished filters from colleagues. We applied the filters to a case study review of diagnostic test accuracy studies for urinary tract infections (UTI) in young children. The included studies with records in MEDLINE formed the gold standard. The performance of the filters in finding those gold standard records was assessed.Results: We identified twenty-three diagnostic test accuracy search filters for use with MEDLINE. The case study systematic review of UTI included 179 studies of diagnostic test accuracy, of which 160 were available in MEDLINE. The filters showed a wide range of sensitivities (range: 20.6% to 86.9%) and precision (range: 1% to 9.4%).Conclusions: Our results broadly support those reported in two other studies. The search filters tested do not offer an adequate trade-off between sensitivity and precision to be used to identify studies for systematic reviews. However, there are methods available to explore whether search filters are viable based on an objective statistical analysis of the text and indexing used in records.
