Background:Systematic reviews are comprehensive, robust, inclusive, transparent, and reproducible when bringing together the evidence to answer a research question. Various guidelines provide recommendations on the expertise required to conduct a systematic review, where and how to search for literature, and what should be reported in the published review. However, the finer details of the search results are not typically reported to allow the search methods or search efficiency to be evaluated.Case Presentation:This case study presents a search summary table, containing the details of which databases were searched, which supplementary search methods were used, and where the included articles were found. It was developed and published alongside a recent systematic review. This simple format can be used in future systematic reviews to improve search results reporting.Conclusions:Publishing a search summary table in all systematic reviews would add to the growing evidence base about information retrieval, which would help in determining which databases to search for which type of review (in terms of either topic or scope), what supplementary search methods are most effective, what type of literature is being included, and where it is found. It would also provide evidence for future searching and search methods research. 相似文献

Objective:There are concerns about nonscientific and/or unclear information on the coronavirus disease 2019 (COVID-19) that is available on the Internet. Furthermore, people''s ability to understand health information varies and depends on their skills in reading and interpreting information. This study aims to evaluate the readability and creditability of websites with COVID-19-related information.Methods:The search terms “coronavirus,” “COVID,” and “COVID-19” were input into Google. The websites of the first thirty results for each search term were evaluated in terms of their credibility and readability using the Health On the Net Foundation code of conduct (HONcode) and Flesch-Kincaid Grade Level (FKGL), Simple Measure of Gobbledygook (SMOG), Gunning Fog, and Flesch Reading Ease Score (FRE) scales, respectively.Results:The readability of COVID-19-related health information on websites was suitable for high school graduates or college students and, thus, was far above the recommended readability level. Most websites that were examined (87.2%) had not been officially certified by HONcode. There was no significant difference in the readability scores of websites with and without HONcode certification.Conclusion:These results suggest that organizations should improve the readability of their websites and provide information that more people can understand. This could lead to greater health literacy, less health anxiety, and the provision of better preventive information about the disease.Open in a separate windowSaeideh Valizadeh-Haghi 相似文献

Objective:Locating systematic reviews is essential for clinicians and researchers when creating or updating reviews and for decision-making in health care. This study aimed to develop a search filter for retrieving systematic reviews that improves upon the performance of the PubMed systematic review search filter.Methods:Search terms were identified from abstracts of reviews published in Cochrane Database of Systematic Reviews and the titles of articles indexed as systematic reviews in PubMed. Both the precision of the candidate terms and the number of systematic reviews retrieved from PubMed were evaluated after excluding the subset of articles retrieved by the PubMed systematic review filter. Terms that achieved a precision greater than 70% and relevant publication types indexed with MeSH terms were included in the filter search strategy.Results:The search strategy used in our filter added specific terms not included in PubMed''s systematic review filter and achieved a 61.3% increase in the number of retrieved articles that are potential systematic reviews. Moreover, it achieved an average precision that is likely greater than 80%.Conclusions:The developed search filter will enable users to identify more systematic reviews from PubMed than the PubMed systematic review filter with high precision. 相似文献

Objective:A growing volume of studies address methods for performing systematic reviews of qualitative studies. One such methodological aspect is the conceptual framework used to structure the review question and plan the search strategy for locating relevant studies. The purpose of this case study was to evaluate the retrieval potential of each element of conceptual frameworks in qualitative systematic reviews in the health sciences.Methods:The presence of elements from conceptual frameworks in publication titles, abstracts, and controlled vocabulary in CINAHL and PubMed was analyzed using a set of qualitative reviews and their included studies as a gold standard. Using a sample of 101 publications, we determined whether particular publications could be retrieved if a specific element from the conceptual framework was used in the search strategy.Results:We found that the relative recall of conceptual framework elements varied considerably, with higher recall for patient/population (99%) and research type (97%) and lower recall for intervention/phenomenon of interest (74%), outcome (79%), and context (61%).Conclusion:The use of patient/population and research type elements had high relative recall for qualitative studies. However, other elements should be used with great care due to lower relative recall. 相似文献

Objective:In regard to locating clinical trials for a systematic review, limited information is available about how librarians locate clinical trials in biomedical databases, including (1) how much information researchers provide librarians to assist with the development of a comprehensive search strategy, (2) which tools librarians turn to for information about study design methodology, and (3) librarians'' confidence levels in their knowledge of study design methodology. A survey was developed to explore these aspects of how a medical librarian locates clinical trials when facilitating systematic reviews for researchers.Methods:In this cross-sectional study, a 21-question survey was sent to medical librarians via several email listservs during April 2020. Respondents were limited to librarians who make the decisions on search terms for systematic reviews.Results:Responses (n=120) indicated that librarians were often asked to search for various types of clinical trials. However, there was not a consistent method for creating search strategies that locate diverse types of clinical trials. Multiple methods were used for search strategy development, with hedges being the most popular method. In general, these librarians considered themselves to be confident in locating trials. Different resources were used to inform study types, including textbooks, articles, library guides and websites.Discussion:Medical librarians indicated that while they felt confident in their searching skills, they did not have a definitive source of information about the various types of clinical trials, and their responses demonstrated a clear need and desire for more information on study design methodology. 相似文献

Objective:The decisions and processes that may compose a systematic search strategy have not been formally identified and categorized. This study aimed to (1) identify all decisions that could be made and processes that could be used in a systematic search strategy and (2) create a hierarchical framework of those decisions and processes.Methods:The literature was searched for documents or guides on conducting a literature search for a systematic review or other evidence synthesis. The decisions or processes for locating studies were extracted from eligible documents and categorized into a structured hierarchical framework. Feedback from experts was sought to revise the framework. The framework was revised iteratively and tested using recently published literature on systematic searching.Results:Guidance documents were identified from expert organizations and a search of the literature and Internet. Data were extracted from 74 eligible documents to form the initial framework. The framework was revised based on feedback from 9 search experts and further review and testing by the authors. The hierarchical framework consists of 119 decisions or processes sorted into 17 categories and arranged under 5 topics. These topics are “Skill of the searcher,” “Selecting information to identify,” “Searching the literature electronically,” “Other ways to identify studies,” and “Updating the systematic review.”Conclusions:The work identifies and classifies the decisions and processes used in systematic searching. Future work can now focus on assessing and prioritizing research on the best methods for successfully identifying all eligible studies for a systematic review. 相似文献

Objective:We previously developed draft MEDLINE and Embase (Ovid) geographic search filters for Organisation for Economic Co-operation and Development (OECD) countries to assess their feasibility for finding evidence about the countries. Here, we describe the validation of these search filters.Methods:We identified OECD country references from thirty National Institute for Health and Care Excellence (NICE) guidelines to generate gold standard sets for MEDLINE (n=2,065) and Embase (n=2,023). We validated the filters by calculating their recall against these sets. We then applied the filters to existing search strategies for three OECD-focused NICE guideline reviews (NG103 on flu vaccination, NG140 on abortion care, and NG146 on workplace health) to calculate the filters'' impact on the number needed to read (NNR) of the searches.Results:The filters both achieved 99.95% recall against the gold standard sets. Both filters achieved 100% recall for the three NICE guideline reviews. The MEDLINE filter reduced NNR from 256 to 232 for the NG103 review, from 38 to 27 for the NG140 review, and from 631 to 591 for the NG146 review. The Embase filter reduced NNR from 373 to 341 for the NG103 review, from 101 to 76 for the NG140 review, and from 989 to 925 for the NG146 review.Conclusion:The NICE OECD countries'' search filters are the first validated filters for the countries. They can save time for research topics about OECD countries by finding the majority of evidence about OECD countries while reducing search result volumes in comparison to no filter use. 相似文献

Abstract An evaluation of the Free Library of Philadelphia's (FLP) rowing collection by the checklist method is reported. A literature review demonstrates that the checklist method has been used for multiple purposes for over a century and a half, but no evaluations of library rowing collections by the checklist or any other method were identified. In this study, an ad hoc70-item list, compiled by a rowing expert, was checked against the FLP's OPAC from a remote location in Indiana. The FLP held 53% of the listed items and no fewer than 40% in any of six topical categories. A keyword search found that the FLP holds over 100 fiction and nonfiction rowing books. An analysis of those titles by publication date shows considerable depth in the FLP collection and a correspondence between its collecting patterns and broader trends in publishing and rowing. It is concluded that the FLP has an in-depth, high quality rowing collection. A number of problems encountered while searching the OPAC are discussed and questions for further research are proposed. 相似文献

We present an engaging and practical exercise in which graduate students grapple with metatheoretical perspectives often presented in their introduction to graduate studies or communication theory courses. To expand their understanding of and engagement with the major elements of the paradigms central to our field, students work in groups to apply and compare various metatheoretical assumptions to a specific research context. The goal of this activity is to strengthen students’ grasp and understanding of these perspectives specifically in the role they hold in guiding one's research study and design. We provide various examples and directions to aid instructors in the presentation of this exercise, as such topics are often challenging from a pedagogical standpoint.

ABSTRACT This article presents a case study in user-centered design that explores the needs and preferences of undergraduate users. An analysis of LibQual+ and other user surveys, interviews with public service staff, and a formal American with Disabilities Act accessibility review served as the basis for planning a redesign of the Brown University Library's Web site. Three testing phases were conducted: individual usability testing of the existing site and baseline data collection on Web use preferences; focus groups to respond to a functional prototype and search prototypes; and individual usability testing and interviews on revised functional prototypes. The delicate task of obtaining staff buy-in without letting their opinion drive the redesign was accomplished by keeping the project team small and nonrepresentational, submitting all conflicts to user testing, and promising an intranet that would meet the specialized needs of staff. A commitment to experimentation and a willingness to jettison design and functional elements which did not meet user approval kept the design process agile and flexible. Prototype testing of a variety of search options clearly demonstrated that the lack of integration in a library's information system makes it difficult to rationalize and optimize the user's search experience. Difficulties enlisting staff to edit existing Web content were solved by outsourcing content review and editing for Web-appropriate length and format. Except for this content review, the Web site redesign and usability testing were all conducted in-house with limited resources and a nine-month time-frame. The study's focus on user expectations and nomenclature largely confirmed the results of previous studies. 相似文献

Abstract This paper addresses some to the problems associated with the ability of elementary school children to successfully retrieve material in the school library media center using either the card or computer catalogues and presents some alternative methods of classification which may help to alleviate these problems. Primary objectives of the paper include inquiry into the need for an alternative method of classification for children, whether children of elementary school age have the ability to successfully use a system of classification, the extent to which the use of colors and/or symbols as search aides may facilitate children/s search efforts and the steps involved in the evolution of such an alternative classification system. Several case studies are examined and a detailed case study of The Common School Library in Amherst, Massachusetts is presented. Findings of this study indicate that children do have the ability to use a classification system which is designed in keeping with their developmental level and that the use of colors and/or symbols as supplementary search tools does facilitate children/s search efforts. The author also presents recommendations regarding the use of alternative systems of classification with other segments of the population who may have difficulty using standard means of library classification. 相似文献

Summary This presentation is a review of the changes in publishing methods that electronic publishing and distribution will involve. It presents a publisher's view of the methodology needed to exploit the potential that online and other electronic technologies offer. Included is a discussion on the role of the paper-based journal in an era of electronic publication, and the ambivalence of scholars and of learned societies toward electronic information. Additionally, the role of universities is examined, as they become partners of publishers in delivering published material to customers on the Internet: by hosting servers, by providing access to bandwidth, and by adding value through participation in the publishing process. 相似文献

Objectives: This module facilitates a process for students to interrogate how they relate to the public and to understand the profound implication of past policies on today’s communities, thereby engaging in productive race talk. Through five successive parts, students are better prepared for effective conversations about race and diversity by: (1) moving progressively toward understanding racial and ethnic identity formation; (2) exploring intersectionality (the oppression resulting from compounding effects of multiple identities) and relative power as it relates to broader socioeconomic, political, and environmental structures; and (3) the historicization of power, privilege, and oppression. 相似文献

BACKGROUND: Cochrane-style systematic reviews increasingly require the participation of librarians. Guidelines on the appropriate search strategy to use for systematic reviews have been proposed. However, research evidence supporting these recommendations is limited. OBJECTIVE: This study investigates the effectiveness of various systematic search methods used to uncover randomized controlled trials (RCTs) for systematic reviews. Effectiveness is defined as the proportion of relevant material uncovered for the systematic review using extended systematic review search methods. The following extended systematic search methods are evaluated: searching subject-specific or specialized databases (including trial registries), hand searching, scanning reference lists, and communicating personally. METHODS: Two systematic review projects were prospectively monitored regarding the method used to identify items as well as the type of items retrieved. The proportion of RCTs identified by each systematic search method was calculated. RESULTS: The extended systematic search methods uncovered 29.2% of all items retrieved for the systematic reviews. The search of specialized databases was the most effective method, followed by scanning of reference lists, communicating personally, and hand searching. Although the number of items identified through hand searching was small, these unique items would otherwise have been missed. CONCLUSIONS: Extended systematic search methods are effective tools for uncovering material for the systematic review. The quality of the items uncovered has yet to be assessed and will be key in evaluating the value of the systematic search methods. 相似文献
