Exploring librarians' practices when teaching advanced searching for knowledge synthesis: results from an online survey.

Objective: There is little research available regarding the instructional practices of librarians who support students completing knowledge synthesis projects. This study addresses this research gap by identifying the topics taught, approaches, and resources that academic health sciences librarians employ when teaching students how to conduct comprehensive searches for knowledge synthesis projects in group settings. Methods: This study applies an exploratory-descriptive design using online survey data collection. The final survey instrument included 31 open, closed, and frequency-style questions. Results: The survey received responses from 114 participants, 74 of whom met the target population. Some key results include shared motivations to teach in groups, including student learning and curriculum requirements, as well as popular types of instruction such as single session seminars, and teaching techniques, such as lectures and live demos. Conclusion: This research demonstrates the scope and coverage of librarian-led training in the knowledge synthesis research landscape. Although searching related topics such as Boolean logic were the most frequent, librarians report teaching throughout the review process like methods and reporting. Live demos and lectures were the most reported approaches to teaching, whereas gamification or student-driven learning were used rarely. Our results suggest that librarian's application of formal pedagogical approaches while teaching knowledge synthesis may be under-utilized, as most respondents did not report using any formal instructional framework.

Understanding the performance of geographic limits on Web of Science Core Collection databases, using the United Kingdom as an example.

Objective: To consider the approaches within Web of Science Core Collection (WoSCC) databases for limiting geographically. To compare the limits to an adaptation of NICE's UK MEDLINE filter for use on WoSCC databases. Methods: We tested and appraised the inbuilt functions and search field options that support identification by countries/regions and affiliations. We compared these with an adapted filter to identify healthcare research on or about the UK. We calculated the recall of the inbuilt limits and filter using 177 studies and investigated why records were missed. We also calculated the percentage reduction of the overall number-needed-to-screen (ONNS). Results: Inbuilt limits within WoSCC enable identification of research from specific countries/regions or affiliations if there is data in the address field. Refining by affiliations allows retrieval of research where affiliations are in the 200 or 500 most frequent for a set of results. An adaptation of the UK MEDLINE filter achieved an average of 97% recall. ONNS was significantly reduced using the filter. However, studies where the countries or regions are only mentioned within the full text or other non-searchable fields will be missed. Conclusion: Information specialists should consider how inbuilt geographic limits operate on WoSCC and whether these are suitable for their research. The adapted filter can sensitively limit to the UK and could be useful for systematic reviews due to its high recall and ability to significantly reduce ONNS. Geographic filters can be feasible to adapt for use on WoSCC databases (where similar search fields are used between platforms).

ChatGPT: Game-changer or wildcard for systematic searching?

In this editorial, Anthea Sutton and Veronica Parisi reflect on ChatGPT, how it may contribute to systematic searching, and provide their overview of some recent training they attended on ChatGPT, AI and systematic literature reviews.

Application of text mining to the development and validation of a geographic search filter to facilitate evidence retrieval in Ovid MEDLINE: An example from the United States.

BACKGROUND: Given the increasing volume of published research in bibliographic databases, efficient retrieval of evidence is crucial and represents an opportunity to integrate novel techniques such as text mining. OBJECTIVES: To develop and validate a geographic search filter for identifying research from the United States (US) in Ovid MEDLINE. METHODS: US and non-US citations were collected from bibliographies of evidence-based reviews. Citations were partitioned by US/non-US status and randomly divided to a training and testing set. Using text mining, common one- and two-word terms in title/abstract fields were identified, and frequencies compared between US/non-US citations. RESULTS: Common US-related terms included (as ratio of frequency in US/non-US citations) US populations and geographic terms [e.g., 'Americans' (15.5), 'Baltimore' (20.0)]. Common non-US terms were non-US geographic terms [e.g., 'Japan' (0.04), 'French' (0.05)]. A search filter was developed with 98.3% sensitivity and 82.7% specificity. DISCUSSION: This search filter will streamline the identification of evidence from the US. Periodic updates may be necessary to reflect changes in MEDLINE's controlled vocabulary. CONCLUSION: Text mining was instrumental to the development of this search filter. A novel technique generated a gold standard set comprising >20,000 citations. This method may be adapted to develop subsequent geographic search filters.

Development of a validated search filter for Ovid Embase for degenerative cervical myelopathy.

BACKGROUND: Degenerative cervical myelopathy (DCM) is a recently proposed umbrella term for symptomatic cervical spinal cord compression secondary to degeneration of the spine. Currently literature searching for DCM is challenged by the inconsistent uptake of the term 'DCM' with many overlapping keywords and numerous synonyms. OBJECTIVES: Here, we adapt our previous Ovid medline search filter for the Ovid embase database, to support comprehensive literature searching. Both embase and medline are recommended as a minimum for systematic reviews. METHODS: References contained within embase identified in our prior study formed a 'development gold standard' reference database (N = 220). The search filter was adapted for embase and checked against the reference database. The filter was then validated against the 'validation gold standard'. RESULTS: A direct translation was not possible, as medline indexing for DCM and the keywords search field were not available in embase. We also used the 'focus' function to improve precision. The resulting search filter has 100% sensitivity in testing. DISCUSSION AND CONCLUSION: We have developed a validated search filter capable of retrieving DCM references in embase with high sensitivity. In the absence of consistent terminology and indexing, this will support more efficient and robust evidence synthesis in the field.

Updated generic search filters for finding studies of adverse drug effects in Ovid medline and Embase may retrieve up to 90% of relevant studies.

BACKGROUND: The most current objectively derived search filters for adverse drug effects are 15 years old and other strategies have not been developed and tested empirically. OBJECTIVE: To develop and validate search filters to retrieve evidence on adverse drug effects from Ovid medline and Ovid Embase. METHODS: We identified systematic reviews of adverse drug effects in Epistemonikos. From these reviews, we collated their included studies which we then randomly divided into three tests and one validation set of records. We constructed a search strategy to maximise relative recall using word frequency analysis with test set one. This search strategy was then refined using test sets two and three and validated on the final set of records. RESULTS: Of 107 systematic reviews which met our inclusion criteria, 1948 unique included studies were available from medline and 1980 from Embase. Generic adverse drug effects searches in medline and Embase achieved 90% and 89% relative recall, respectively. When specific adverse effects terms were added recall was improved. CONCLUSION: We have derived and validated search filters that retrieve around 90% of records with adverse drug effects data in medline and Embase. The addition of specific adverse effects terms is required to achieve higher recall.

Integrating diversity, equity, and inclusion principles into instruction: Case studies from the University of Florida's Health Science Center Libraries.

Librarians at the University of Florida Health Science Center Libraries have begun to intentionally incorporate diversity, equity, and inclusion (DEI) principles into teaching during design, implementation, and evaluation. This article uses four case studies to provide an overview of the librarians' approaches to inclusive teaching (1) an annual workshop for Physical Therapy students on the intersection between DEI, health literacy, and patient education; (2) a librarian-taught one-credit course for public health students, which was revised to create a more inviting syllabus and integrate elements of universal design; (3) an annual project for first year medical students highlighting health disparities and community resources; and (4) piloting the application of critical librarianship principles in library standalone sessions on database searching and reference management. Suggestions are provided for other librarians who are interested in developing a culture of inclusive teaching in their own libraries.

Determining COVID-19's impact on an academic medical library's literature search service.

Objective: At many institutions, literature search services are an important aspect of health science librarianship. This exploratory study analyzes how the COVID-19 pandemic impacted the use of an academic hospital medical library's literature search service. Methods: To evaluate the pandemic's impact on literature searching at The University of Tennessee Medical Center's Preston Medical Library, data were analyzed for changes from the year before the pandemic (March 1, 2019 to February 29, 2020) to the first year during the pandemic (March 1st, 2020 to February 28, 2021). This was accomplished using LibWizard, a library feedback and assessment application, to review literature search data during the two periods. Variables of interest included total searches, purpose of searches, affiliation of the searcher, and searches with a pandemic-related research question. Results: A 36.6% drop in literature search service usage was reported from the pre-pandemic year to the during-pandemic year. There was a 55.3% decrease in searches intended for research, as well as significant decreases in the number of searches requested by all patron affiliations. After March 2020, 10% of all searches concerned a COVID-related topic. Conclusion: The overall decrease in literature search requests, decrease in research searches, decrease in searches among all patron affiliations, and increase in searches on a COVID-related topic suggest that healthcare worker and institutional priorities changed during the pandemic. The results revealed research interests during the first year of the pandemic, as well as an overall change in library service functionality.

Adapting to Changes in Publishing When Searching for Alternatives and Reporting on Animal Research: A Librarian's Perspective.

Since the inaugural issue of ATLA, many changes within publishing have occurred, impacting when, where, and how researchers conduct literature searches for non-animal alternatives. Such changes include increased rate of growth in scientific publications, greater number of databases and online resources available to search, opportunities for open and almost immediate dissemination of research outputs such as preprints and method protocols, and the development of reporting guidelines for animal research. Here we offer a librarian's perspective on these changes and advice on how to manage them to enable robust and diverse alternatives to be implemented in future research.

Finding and evaluating randomised controlled trials in nursing conducted by Spanish research teams: A scoping review.

BACKGROUND/OBJECTIVES: To identify and assess the main characteristics and the potential risk of bias of randomised controlled trials (RCTs) in nursing conducted by Spanish research teams. METHODS: Scoping review of an electronic search in three major databases (date of search: October 2021). For the eligible studies, both descriptive data, and data to assess the potential risk of bias, were collected and analysed. RESULTS: Of 3391 references retrieved, 199 were eligible. These RCTs were published in 122 journals, most of them in English (101, 82.1%) and were included in the Journal Citation Report (JCR) (107, 87.7%). Moreover, 32 (26.2%) of those included in the JCR were classified under nursing. Two thirds (81, 66.4%) of the journals followed the CONSORT guidelines. A total of 65 RCTs (33.7%) had a high overall risk of bias. DISCUSSION: Most of the identified RCTs were published in journals not specific to nursing and in English language. Also, shortcomings in RCT design and reporting were observed despite recommendations to adhere the CONSORT guidelines. CONCLUSION: Comprehensive identification of RCTs in nursing may require searching in journals other than nursing-related. RCTs from Spanish research teams are more likely to be published in international journals published in English. CONSORT should be strongly advised to encourage proper design and reporting of RCTs.

NHS librarians collaborate to develop a search bank peer reviewing and sharing COVID-19 searches: an evaluation.

BACKGROUND: Responding to the COVID-19 pandemic, Health Education England (HEE) mobilised a group of expert searchers from NHS libraries in England to develop a platform for librarians to share peer reviewed search strategies and results on the Knowledge for Healthcare website. OBJECTIVES: (1) To document the origins of the COVID-19 search bank, (2) evaluate attitudes of NHS librarians in England towards the search bank and (3) identify lessons learned and consider whether the initiative might be developed further. METHODS: Structured interviews with the peer reviewers (n = 10) were conducted, and a questionnaire survey of the NHS library community using the search bank was undertaken. RESULTS: The interviews confirmed the value of collaboration. Expert searchers worked in pairs to peer review submitted search strategies. The survey (85 responses) indicated that a majority had used the search bank, and approved of the project, with some differences of opinion on functionality and future developments. DISCUSSION: Collaborative working for the search bank probably saved time for individual NHS librarians. The quality of the searches submitted was variable as were librarians' approaches to presentation and development of search strategies. Peer review benefits from a buddy approach among expert searchers and agreement about feedback provided to contributors. CONCLUSION: Search strategies are the most useful element of a search bank. Peer review can be challenging and would benefit from a formal structure, but it is professionally rewarding.

Landscape of health sciences librarian-mediated search services.

BACKGROUND: Health librarians have traditionally provided mediated searches to support patient care, education and research. OBJECTIVES: This study aims to discover the types of search result formats used by health science libraries, determine current practice among health science libraries (types of requesters served, fees, deduplication, turnaround time and citation manager use) and uncover innovative methods for providing search results. METHODS: An online survey was distributed to the MEDLIB-L, ExpertSearching, MidContinental Chapter of the Medical Library Association and ICON listservs and through direct email to selected Association of Academic Health Sciences Libraries reference and education librarians. RESULTS: Librarians affiliated with 127 institutions from 11 countries (including the USS) and 36 USS states and territories responded. One hundred and forty-two of the total 150 analysed responses provided information on full-text access, and 81 of those 142 responses (57%) indicated that the institutions' link-resolver links were included in search results provided to the requester. The survey responses provide information on literature search services regarding turnaround time, use of a citation managers, fees and deduplication. CONCLUSION: With the developing landscape of citation managers and the tools offered, these data can be used as a benchmark for librarians who are considering evaluating or modifying their search service delivery.

Literature searching methods or guidance and their application to public health topics: A narrative review.

BACKGROUND: Information specialists conducting searches for systematic reviews need to consider key questions around which and how many sources to search. This is particularly important for public health topics where evidence may be found in diverse sources. OBJECTIVES: The objective of this review is to give an overview of recent studies on information retrieval guidance and methods that could be applied to public health evidence and used to guide future searches. METHODS: A literature search was performed in core databases and supplemented by browsing health information journals and citation searching. Results were sifted and reviewed. RESULTS: Seventy-two papers were found and grouped into themes covering sources and search techniques. Public health topics were poorly covered in this literature. DISCUSSION: Many researchers follow the recommendations to search multiple databases. The review topic influences decisions about sources. Additional sources covering grey literature eliminate bias but are time-consuming and difficult to search systematically. Public health searching is complex, often requiring searches in multidisciplinary sources and using additional methods. CONCLUSIONS: Search planning is advisable to enable decisions about which and how many sources to search. This could improve with more work on modelling search scenarios, particularly in public health topics, to examine where publications were found and guide future research.

Google is goodish: An information literacy course designed to teach users why Google may not always be the best place to search for evidence.

This article describes a course that was developed in response to health sector and local authority workers being reliant on Google and using it for their information needs regardless of whether it was the best place to search. The methodology for developing and structuring the course is explored, including details of the content included. The author concludes by asserting that teaching users about the effective use of Google is an important part of user education. D.I.

The NICE OECD countries' geographic search filters: Part 2-validation of the MEDLINE and Embase (Ovid) filters.

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.

The NICE OECD countries' geographic search filters: Part 1-methodology for developing the draft MEDLINE and Embase (Ovid) filters.

OBJECTIVE: There are no existing validated search filters for the group of 37 Organisation for Economic Co-operation and Development (OECD) countries. This study describes how information specialists from the United Kingdom's National Institute for Health and Care Excellence (NICE) developed and evaluated novel OECD countries' geographic search filters for MEDLINE and Embase (Ovid) to improve literature search effectiveness for evidence about OECD countries. METHODS: We created the draft filters using an alternative approach to standard filter construction. They are composed entirely of geographic subject headings and are designed to retain OECD country evidence by excluding non-OECD country evidence using the NOT Boolean operator. To evaluate the draft filters' effectiveness, we used MEDLINE and Embase literature searches for three NICE guidelines that retrieved >5,000 search results. A 10% sample of the excluded references was screened to check that OECD country evidence was not inadvertently excluded. RESULTS: The draft MEDLINE filter reduced results for each NICE guideline by 9.5% to 12.9%. In Embase, search results were reduced by 10.7% to 14%. Of the sample references, 7 of 910 (0.8%) were excluded inadvertently. These references were from a guideline about looked-after minors that concerns both OECD and non-OECD countries. CONCLUSION: The draft filters look promising-they reduced search result volumes while retaining most OECD country evidence from MEDLINE and Embase. However, we advise caution when using them in topics about both non-OECD and OECD countries. We have created final versions of the search filters and will validate them in a future study.

Overlaps of multiple database retrieval and citation tracking in dementia care research: a methodological study.

OBJECTIVE: We aimed to determine overlaps and optimal combination of multiple database retrieval and citation tracking for evidence synthesis, based on a previously conducted scoping review on facilitators and barriers to implementing nurse-led interventions in dementia care. METHODS: In our 2019 scoping review, we performed a comprehensive literature search in eight databases (CENTRAL, CINAHL, Embase, Emcare, MEDLINE, Ovid Nursing Database, PsycINFO, and Web of Science Core Collection) and used citation tracking. We retrospectively analyzed the coverage and overlap of 10,527 retrieved studies published between 2015 and 2019. To analyze database overlap, we used cross tables and multiple correspondence analysis (MCA). RESULTS: Of the retrieved studies, 6,944 were duplicates and 3,583 were unique references. Using our search strategies, considerable overlaps can be found in some databases, such as between MEDLINE and Web of Science Core Collection or between CINAHL, Emcare, and PsycINFO. Searching MEDLINE, CINAHL, and Web of Science Core Collection and using citation tracking were necessary to retrieve all included studies of our scoping review. CONCLUSIONS: Our results can contribute to enhancing future search practice related to database selection in dementia care research. However, due to limited generalizability, researchers and librarians should carefully choose databases based on the research question. More research on optimal database retrieval in dementia care research is required for the development of methodological standards.

Who is blocking access to PubMed? Educational 'Escape Room' for medical residents.

Teaching students how to conduct bibliographic searches in health sciences' databases is essential training. One of the challenges librarians face is how to motivate students during classroom learning. In this article, two hospital libraries, in Spain, used Escape rooms as a method of bringing creativity, teamwork, communication and critical thinking into bibliographic search instruction. Escape rooms are a series of puzzles that must be solved to exit the game. This article explores the methods used for integrating escape rooms into training programmes and evaluates the results. Escape Rooms are a useful tool that can be integrated into residents' training to support their instruction on bibliographic searches. This kind of learning stablishes competences like logical thinking and deductive approaching. These aspects aid participants to make their own decision and to develop social and intellectual skills.

Adoption of peer review of literature search strategies in knowledge synthesis from 2009 to 2018: An overview.

BACKGROUND: Knowledge synthesis (KS) reviews rely on good quality literature searches to capture a complete set of relevant studies, and peer review of the search strategy is one quality control mechanism that contributes to better quality reviews. Guidelines for peer review of electronic search strategies (PRESS) have been available since 2008. OBJECTIVES: This overview provides a snapshot of KS indexed in Scopus, published between 2009 and 2018, that reported peer review of the literature search strategy. METHODS: Articles were identified through citation chasing for PRESS guidance documents and supplementary keyword searches. The characteristics of individual articles and the journals that published them were documented, and descriptive statistics were compiled. RESULTS: 415 articles from 169 journals met inclusion criteria. Approximately half were published in 14 journal titles. Most reviews reported the involvement of an information professional, but PRESS reviewers were rarely acknowledged. An overwhelming majority of review teams were based in Canada. DISCUSSION: Reported use of PRESS was low during the period examined, but under-reporting may be a factor. Investigation of the barriers and facilitators of PRESS adoption is needed. CONCLUSION: Despite its value, adoption of PRESS appears low. Advocacy for, and education about, PRESS may be required.
