目的：本研究的目的是量化的唯一有用的收益从累积索引护理和相关健康文献（CINAHL）数据库的国家卫生和临床卓越研究所（NICE）的临床指南。次要目的是研究该收益率与不同临床问题类型之间的关系。据推测，从CINAHL的独特有用的产量是低的，因此，这个数据库可以被降级到选择性的，而不是常规searching.Study设计和设置：回顾性样本的15 NICE指南发表于2005年和2009年之间。临床综述问题类型，参考文献数量和参考文献来源的信息被提取。结果：只有0.33%（95%置信区间：0.01-0.64%）的参考文献每指南是唯一的CINAHL。护理或专职医疗（AH）相关问题中CINAHL特有参考文献的可能性几乎是非护理或AH相关问题的三倍（14.89% vs. 5.11%），并且发现这种关系具有显著性（P < 0.05）。问题类型和独特的CINAHL产量之间没有显着的关系被发现为drug-related questions.Conclusions：CINAHL独特的参考文献的比例非常低，这强烈表明，这个数据库可以安全地降级到选择性的，而不是常规的搜索。护理和AH相关问题将受益于CINAHL的选择性搜索。(C)2013 Elsevier Inc.

Objectives: This study aims to quantify the unique useful yield from the Cumulative Index to Nursing and Allied Health Literature (CINAHL) database to National Institute for Health and Clinical Excellence (NICE) clinical guidelines. A secondary objective is to investigate the relationship between this yield and different clinical question types. It is hypothesized that the unique useful yield from CINAHL is low, and this database can therefore be relegated to selective rather than routine searching.Study Design and Setting: A retrospective sample of 15 NICE guidelines published between 2005 and 2009 was taken. Information on clinical review question type, number of references, and reference source was extracted.Results: Only 0.33% (95% confidence interval: 0.01-0.64%) of references per guideline were unique to CINAHL. Nursing- or allied health (AH)-related questions were nearly three times as likely to have references unique to CINAHL as non-nursing- or AH-related questions (14.89% vs. 5.11%), and this relationship was found to be significant (P < 0.05). No significant relationship was found between question type and unique CINAHL yield for drug-related questions.Conclusions: The very low proportion of references unique to CINAHL strongly suggests that this database can be safely relegated to selective rather than routine searching. Nursing- and AH-related questions would benefit from selective searching of CINAHL. (C) 2013 Elsevier Inc. All rights reserved.
