  • erratum to what value is the Cinahl database when searching for systematic reviews of qualitative studies
    Systematic Reviews, 2015
    Co-Authors: Kath Wright, Su Golder, Kate Lewislight
    Abstract:

    Erratum After publication of [1] it came to the authors’ attention that three percentage (%) symbols were missed upon publication of their manuscript. The incorrect statement present in the Abstract and Results is “The median number of unique studies was 9.09; while the range had a lowest value of 5.0 to the highest value of 33.0”. The correct statement is “The median % of unique studies was 9.09%; while the range had a lowest value of 5.0% to the highest value of 33.0%”. This has been updated in the original article.

  • what value is the Cinahl database when searching for systematic reviews of qualitative studies
    Systematic Reviews, 2015
    Co-Authors: Kath Wright, Su Golder, Kate Lewislight
    Abstract:

    The Cumulative Index to Nursing and Allied Health Literature (Cinahl) is generally thought to be a good source to search when conducting a review of qualitative evidence. Case studies have suggested that using Cinahl could be essential for reviews of qualitative studies covering topics in the nursing field, but it is unclear whether this can be extended more generally to reviews of qualitative studies in other topic areas. We carried out a retrospective analysis of a sample of systematic reviews of qualitative studies to investigate Cinahl’s potential contribution to identifying the evidence. In particular, we planned to identify the percentage of included studies available in Cinahl and the percentage of the included studies unique to the Cinahl database. After screening 58 qualitative systematic reviews identified from the Database of Abstracts of Reviews of Effects (DARE), we created a sample set of 43 reviews covering a range of topics including patient experience of both illnesses and interventions. For all 43 reviews (21 %) in our sample, we found that some of the included studies were available in Cinahl. For nine of these reviews, all the studies that had been included in the final synthesis were available in the Cinahl database, so it could have been possible to identify all the included studies using just this one database, while for an additional 21 reviews (49 %), 80 % or more of the included studies were available in Cinahl. Consequently, for a total of 30 reviews, or 70 % of our sample, 80 % or more of the studies could be identified using Cinahl alone. 11 reviews, where we were able to recheck all the databases used by the original review authors, had included a study that was uniquely identified from the Cinahl database. The median % of unique studies was 9.09 %; while the range had a lowest value of 5.0 % to the highest value of 33.0 %. Assuming a rigorous search strategy was used and the records sought were accurately indexed, we could expect Cinahl to be a good source of primary studies for qualitative evidence syntheses. While we found some indication that Cinahl had the potential to provide unique studies for systematic reviews, we could only fully test this on a limited number of reviews, so we are less confident about this finding.

  • finding knowledge translation articles in Cinahl
    Studies in health technology and informatics, 2010
    Co-Authors: Cynthia Lokker, Nancy L Wilczynski, Brian R Haynes, Ann K Mckibbon, Donna Ciliska, Maureen Dobbins, David A Davis, Sharon E Straus
    Abstract:

    BACKGROUND The process of moving research into practice has a number of names including knowledge translation (KT). Researchers and decision makers need to be able to readily access the literature on KT for the field to grow and to evaluate the existing evidence. METHODS To develop and validate search filters for finding KT articles in the database Cumulative Index to Nursing and Allied Health (Cinahl). A gold standard database was constructed by hand searching and classifying articles from 12 journals as KT Content, KT Applications and KT Theory. MAIN OUTCOME MEASURES Sensitivity, specificity, precision, and accuracy of the search filters. RESULTS Optimized search filters had fairly low sensitivity and specificity for KT Content (58.4% and 64.9% respectively), while sensitivity and specificity increased for retrieving KT Application (67.5% and 70.2%) and KT Theory articles (70.4% and 77.8%). CONCLUSION Search filter performance was suboptimal marking the broad base of disciplines and vocabularies used by KT researchers. Such diversity makes retrieval of KT studies in Cinahl difficult.

  • cumulative index to nursing and allied health literature search strategies for identifying methodologically sound causation and prognosis studies
    Applied Nursing Research, 2008
    Co-Authors: Cindy Walkerdilks, Nancy L Wilczynski, Brian R Haynes
    Abstract:

    We developed search strategies for detecting sound articles on causation and prognosis in Cumulative Index to Nursing and Allied Health Literature (Cinahl) in the year 2000. An analytic survey was conducted, comparing hand searches of 75 journals with retrievals from Cinahl for 5,020 search terms and 11,784 combinations for causation and 9,946 combinations for prognosis. For detecting sound causation studies, a three-term strategy maximized sensitivity at 97.0% with a specificity of 52.3%. For detecting sound prognosis studies, a three-term strategy maximized sensitivity at 92.2% with a specificity of 50.0%. These search filters will enhance the searching efforts of clinicians and researchers.

  • search strategies for identifying qualitative studies in Cinahl
    Qualitative Health Research, 2007
    Co-Authors: Nancy L Wilczynski, Susan Marks, Brian R Haynes
    Abstract:

    Nurses, allied health professionals, clinicians, and researchers increasingly use online access to evidence in the course of patient care or when conducting reviews on a particular topic. Qualitative research has an important role in evidence-based health care. Online searching for qualitative studies can be difficult, however, resulting in the need to develop search filters. The objective of this study was to develop optimal search strategies to retrieve qualitative studies in Cinahl for the 2000 publishing year. The authors conducted an analytic survey comparing hand searches of journals with retrievals from Cinahl for candidate search terms and combinations. Combinations of search terms reached peak sensitivities of 98.9% and peak specificities of 99.5%. Combining search terms optimized both sensitivity and specificity at 94.2%. Empirically derived search strategies combining indexing terms and textwords can achieve high sensitivity and high specificity for retrieving qualitative studies from Cinahl.

  • optimal Cinahl search strategies for identifying therapy studies and review articles
    Journal of Nursing Scholarship, 2006
    Co-Authors: Sharon Wong, Nancy L Wilczynski, Brian R Haynes
    Abstract:

    Purpose: To design optimal search strategies for locating sound therapy studies and review articles in Cinahl in the year 2000. Design and Methods: An analytic survey was conducted, comparing hand searches of 75 journals with retrievals from Cinahl for 5,020 candidate search terms and 17,900 combinations for therapy and 5,977 combinations for review articles. All articles were rated with purpose and quality indicators. Candidate search strategies were used in Cinahl, and the retrievals were compared with results of the hand searches. The proposed search strategies were treated as “diagnostic tests” for sound studies and the manual review of the literature was treated as the “gold standard.” Operating characteristics of the search strategies were calculated. Findings: Of the 1,383 articles about treatment, 506 (36.6%) met basic criteria for scientific merit and 127 (17.9%) of the 711 articles classified as a review met the criteria for systematic reviews. For locating sound treatment studies, a three-term strategy maximized sensitivity at 99.4% but with compromised specificity at 58.3%, and a two-term strategy maximized specificity at 98.5% but with compromised sensitivity at 52.0%. For detecting systematic reviews, a three-term strategy maximized sensitivity at 91.3% while keeping specificity high at 95.4%, and a single-term strategy maximized specificity at 99.6% but with compromised sensitivity at 42.5%. Three-term search strategies optimizing sensitivity and specificity achieved these values over 91% for detecting sound treatment studies and over 76% for detecting systematic reviews. Conclusions: Search strategies combining indexing terms and text words can achieve high sensitivity and specificity for retrieving sound treatment studies and review articles in Cinahl.
