The reporting of the search methods used in systematic reviews has implications for how systematic reviews are critically appraised, their reproducibility and how easily they may be updated. The objective of this paper was to identify validated or evaluated search reporting instruments used in reporting systematic review searches and to compare reported and recommended searching practices.
This cohort study was a systematic review. The search strategy to identify instruments addressing the reporting of search strategies was developed first in the Library & Information Science Abstracts (LISAs) database and then adapted for MEDLINE and five additional databases. Additional instruments were identified through experts. Current reporting practice data were analyzed from a cohort of 297 recent systematic reviews.
Of the 11 instruments examined, 7 cited supporting evidence but only 4 were validated. Eighteen different reporting items were identified but only one item, "databases used," appeared in all instruments. There was a trend toward including more items in more recent instruments (r=0.41). Current search reporting practices ranged from a high of 98.7% for databases used to a low of 11.4% for qualifications of the searcher.
There is no clear consensus regarding optimum reporting of systematic review search methods and commonly recommended items show suboptimal reporting.
系统评价中所采用检索方法的报告，对于系统评价如何进行严格评估、其可重复性以及更新的难易程度均有影响。本文的目的是识别用于报告系统评价检索的经过验证或评估的检索报告工具，并比较报告的检索实践与推荐的检索实践。
这项队列研究是一项系统评价。用于识别涉及检索策略报告的工具的检索策略，首先在图书馆与信息科学文摘（LISAs）数据库中制定，然后适用于MEDLINE和另外五个数据库。通过专家识别出其他工具。从297项近期系统评价的队列中分析当前的报告实践数据。
在所审查的11种工具中，7种引用了支持证据，但只有4种经过验证。识别出18个不同的报告项目，但所有工具中仅出现一个项目“所使用的数据库”。在更新的工具中存在纳入更多项目的趋势（r = 0.41）。当前的检索报告实践范围从“所使用的数据库”的98.7%的高报告率到“检索者资质”的11.4%的低报告率。
关于系统评价检索方法的最佳报告尚无明确共识，且通常推荐的项目显示报告欠佳。
