CINAHL is not listed as one of the minimum databases for systematic review (SR) of interventions in the Methodological Expectations of the Cochrane Intervention Review.
To determine additional studies uniquely identified from the CINAHL search in SR of health services interventions (HSI).
We searched PubMed from inception to October 1, 2022 to identify SRs of HSI that determined clinical or humanistic outcomes of HSI and used CINAHL. Out of 5655 Systematic reviews identified, we randomly selected 374 SRs and extracted all primary studies included. We then explored the bibliographic databases in which the journals of those studies were indexed. The outcome of interest was the number of studies uniquely available in CINHAL. We also performed a subgroup analysis based on the type of HSI. We performed descriptive statistics to report the study outcomes using Excel (Microsoft 365).
A total of 7550 primary studies were identified from the 374 Systematic reviews that met the inclusion criteria. Of these studies, 7380 were journal publications that have been indexed in MEDLINE/PubMed (75.1%), Scopus (74.5%), Sciences Citation Index, SCI (54.7%), Embase (48.1%), and CINAHL (34.9%). Only 83 out of 7380 (1.1%) studies were published in journals that were uniquely indexed in CINAHL. The percentage of studies that were only available in other databases was 9.7% (Scopus), 4.3% (MEDLINE/PubMed), 1.6% (SCI), and 0.3% (Embase). The number of studies that were unique to CINAHL in specific types of HSI were: 24/1570 (1.5%) for community health services, 20/1520 (1.3%) for preventive health services, 45/3624 (1.2%) for patient care, 8/1173 (0.7%) for mental health services, and 18/2804 (0.6%) for rehabilitation.
The gain of CINAHL to identify unique primary studies for SR of HSI appears minimal. The impact of missing studies uniquely available in CINAHL on SR summary or magnitude of effect estimates from meta-analysis requires further investigation.
在《Cochrane干预性综述的方法学期望》中，CINAHL未被列为干预性系统综述（SR）的最低要求数据库之一。
确定在卫生服务干预（HSI）的系统综述中通过检索CINAHL唯一识别出的其他研究。
我们检索了从创刊至2022年10月1日的PubMed，以识别确定HSI临床或人文结局并使用了CINAHL的HSI系统综述。在识别出的5655篇系统综述中，我们随机选择了374篇系统综述，并提取了其中纳入的所有原始研究。然后，我们探索了这些研究所在期刊被索引的书目数据库。感兴趣的结果是CINHAL中唯一可获取的研究数量。我们还根据HSI的类型进行了亚组分析。我们使用Excel（Microsoft 365）进行描述性统计以报告研究结果。
从374篇符合纳入标准的系统综述中总共识别出7550项原始研究。在这些研究中，7380项是已在MEDLINE/PubMed（75.1%）、Scopus（74.5%）、科学引文索引（SCI，54.7%）、Embase（48.1%）和CINAHL（34.9%）中被索引的期刊出版物。在7380项研究中，只有83项（1.1%）发表在仅在CINAHL中被索引的期刊上。仅在其他数据库中可获取的研究百分比分别为：Scopus为9.7%、MEDLINE/PubMed为4.3%、SCI为1.6%、Embase为0.3%。特定类型HSI中CINAHL独有的研究数量分别为：社区卫生服务24/1570（1.5%）、预防保健服务20/1520（1.3%）、患者护理45/3624（1.2%）、心理健康服务8/1173（0.7%）、康复18/2804（0.6%）。
CINAHL在为HSI的系统综述识别独特原始研究方面的收获似乎微乎其微。CINAHL中唯一可获取的缺失研究对系统综述总结或荟萃分析效应估计大小的影响需要进一步研究。
