Abstract

BACKGROUND

There are few publications on search strategies to identify diagnostic test accuracy (DTA) studies in lilacs.

OBJECTIVE

To translate and customise medline search strategies for use in lilacs and assess their retrieval of studies in Cochrane DTA systematic reviews.

METHOD

We developed a six-step process to translate and customise medline search strategies for use in lilacs (iAHx interface). We identified medline search strategies of published Cochrane DTA reviews, translated/customised them for use in lilacs, ran searches in lilacs and compared the retrieval results of our translated search strategy versus the one used in the published reviews.

RESULTS

Our lilacs search strategies translated/customised from the medline strategies retrieved studies in 70 Cochrane DTA reviews. Only 29 of these reviews stated that they had searched the lilacs database and 21 published their lilacs search strategies. Few had used the lilacs database search tools, none exploded the subject headings, and 86% used only English terms.

CONCLUSION

Translating and tailoring a medline search strategy for the lilacs database resulted in the retrieval of DTA studies that would have been missed otherwise.

摘要

背景

在 lilacs 数据库中，很少有关于检索诊断测试准确性（DTA）研究的搜索策略的出版物。

目的

翻译和定制用于 lilacs 数据库的 medline 搜索策略，并评估其在 Cochrane DTA 系统评价中检索研究的效果。

方法

我们开发了一个六步流程，用于将 medline 搜索策略翻译成适用于 lilacs 数据库的搜索策略（iAHx 界面）。我们确定了已发表的 Cochrane DTA 综述中的 medline 搜索策略，将其翻译成适用于 lilacs 数据库的搜索策略，在 lilacs 数据库中进行检索，并比较我们翻译的搜索策略与发表的综述中使用的搜索策略的检索结果。

结果

我们从 medline 策略翻译/定制的 lilacs 搜索策略检索到了 70 篇 Cochrane DTA 综述中的研究。这些综述中只有 29 篇表示他们已经检索了 lilacs 数据库，其中 21 篇发表了他们的 lilacs 搜索策略。很少有研究使用了 lilacs 数据库的搜索工具，没有对主题词进行扩展，并且 86%的研究仅使用了英文术语。
