To determine if librarian collaboration was associated with improved database search quality, search reproducibility, and systematic review reporting in otolaryngology systematic reviews and meta-analyses.
In this retrospective cross-sectional study, PubMed was queried for systematic reviews and meta-analyses published in otolaryngology journals in 2010, 2015, and 2021. Two researchers independently extracted data. Two librarians independently rated search strategy reproducibility and quality for each article. The main outcomes include association of librarian involvement with study reporting quality, search quality, and publication metrics in otolaryngology systematic reviews and meta-analyses. Categorical data were compared with Chi-Squared tests or Fisher's Exact tests. Continuous variables were compared via Mann Whitney U Tests for two groups, and Kruskal-Wallis Tests for three or more groups.
Of 559 articles retrieved, 505 were analyzed. More studies indicated librarian involvement in 2021 (n=72, 20.7%) compared to 2015 (n=14, 10.4%) and 2010 (n=2, 9.0%) (p=0.04). 2021 studies showed improvements in properly using a reporting tool (p<0.001), number of databases queried (p<0.001), describing date of database searches (p<0.001), and including a flow diagram (p<0.001). Librarian involvement was associated with using reporting tools (p<0.001), increased number of databases queried (p<0.001), describing date of database search (p=0.002), mentioning search peer reviewer (p=0.02), and reproducibility of search strategies (p<0.001). For search strategy quality, librarian involvement was associated with greater use of "Boolean & proximity operators" (p=0.004), "subject headings" (p<0.001), "text word searching" (p<0.001), and "spelling/syntax/line numbers" (p<0.001). Studies with librarian involvement were associated with publication in journals with higher impact factors for 2015 (p=0.003) and 2021 (p<0.001).
Librarian involvement was associated with improved reporting quality and search strategy quality. Our study supports the inclusion of librarians in review teams, and journal editing and peer reviewing teams.
确定图书馆员的合作是否与改善耳鼻喉科系统评价和荟萃分析中的数据库搜索质量、搜索可重复性和系统评价报告有关。
在这项回顾性的横断面研究中，我们在耳鼻喉科期刊上检索了 2010 年、2015 年和 2021 年发表的系统评价和荟萃分析。两名研究人员独立提取数据。两名图书馆员独立评估了每篇文章的搜索策略可重复性和质量。主要结果包括图书馆员参与与耳鼻喉科系统评价和荟萃分析中的研究报告质量、搜索质量和发表指标的关联。分类数据采用卡方检验或 Fisher 精确检验进行比较。对于两组连续变量采用 Mann-Whitney U 检验进行比较，对于三组或更多组连续变量采用 Kruskal-Wallis 检验进行比较。
在检索到的 559 篇文章中，有 505 篇进行了分析。与 2015 年（n=14，10.4%）和 2010 年（n=2，9.0%）相比，2021 年的研究（n=72，20.7%）中表示有图书馆员参与的研究更多（p=0.04）。2021 年的研究在正确使用报告工具（p<0.001）、查询数据库的数量（p<0.001）、描述数据库搜索日期（p<0.001）和包括流程图（p<0.001）方面均有改进。图书馆员的参与与使用报告工具（p<0.001）、查询数据库的数量增加（p<0.001）、描述数据库搜索日期（p=0.002）、提及搜索同行评审员（p=0.02）和搜索策略的可重复性（p<0.001）有关。在搜索策略质量方面，图书馆员的参与与更广泛地使用“布尔运算符和邻近运算符”（p=0.004）、“主题词”（p<0.001）、“文本词搜索”（p<0.001）和“拼写/语法/行号”（p<0.001）有关。有图书馆员参与的研究与 2015 年（p=0.003）和 2021 年（p<0.001）发表在影响因子较高的期刊上有关。
图书馆员的参与与改善报告质量和搜索策略质量有关。我们的研究支持在审查团队、期刊编辑和同行评审团队中纳入图书馆员。
