Objective

The choice of bibliographic database during the systematic review search process has been an ongoing conversation among information specialists. With newer information sources, such as Google Scholar and clinical trials registries, we were interested in which databases were utilized by information specialists and systematic review researchers.

Method

We retrieved 144 systematic reviews and meta-analyses from 4 clinical endocrinology journals and extracted all information sources used during the search processes.

Results

Findings indicate that traditional bibliographic databases are most often used, followed by regional databases, clinical trials registries, and gray literature databases.

Conclusions

This study informs information specialists about additional resources that may be considered during the search process.  相似文献

Objectives

There is little research on pediatric hospitalists'' use of evidence-based resources. The aim of this study was to determine the electronic resources that pediatric hospitalists prefer.

Methods

Using a web-based survey, the authors determined hospitalists'' preferred electronic resources, as well as their attitudes toward lifelong learning, practice, and experience characteristics.

Results

One hundred sixteen hospitalists completed the survey. The most preferred resource for general information, patient handouts, and treatment was UpToDate. Online search engines were ranked second for general information and patient handouts.

Conclusions

Pediatric hospitalists tend to utilize less rigorous electronic resources such as UpToDate and Google. These results can set a platform for discussing the quality of resources that pediatric hospitalists use.  相似文献

Objective

The authors sought to determine whether unexpected gaps existed in Scopus''s author affiliation indexing of publications written by the University of Nebraska Medical Center or Nebraska Medicine (UNMC/NM) authors during 2014.

Methods

First, we compared Scopus affiliation identifier search results to PubMed affiliation keyword search results. Then, we searched Scopus using affiliation keywords (UNMC, etc.) and compared the results to PubMed affiliation keyword and Scopus affiliation identifier searches.

Results

We found that Scopus''s records for approximately 7% of UNMC/NM authors'' publications lacked appropriate UNMC/NM author affiliation identifiers, and many journals'' publishers were supplying incomplete author affiliation information to PubMed.

Conclusions

Institutions relying on Scopus to track their impact should determine whether Scopus''s affiliation identifiers will, in fact, identify all articles published by their authors and investigators.  相似文献

Objective:

The objective of this study was to validate an assessment instrument for MEDLINE search strategies at an academic medical center.

Method:

Two approaches were used to investigate if the search assessment tool could capture performance differences in search strategy construction. First, data from an evaluation of MEDLINE searches from a pediatric resident''s longitudinal assessment were investigated. Second, a cross-section of search strategies from residents in one incoming class was compared with strategies of residents graduating a year later. MEDLINE search strategies formulated by faculty who had been identified as having search expertise were used as a gold standard comparison. Participants were presented with a clinical scenario and asked to identify the search question and conduct a MEDLINE search. Two librarians rated the blinded search strategies.

Results:

Search strategy scores were significantly higher for residents who received training than the comparison group with no training. There was no significant difference in search strategy scores between senior residents who received training and faculty experts.

Conclusion:

The results provide evidence for the validity of the instrument to evaluate MEDLINE search strategies. This assessment tool can measure improvements in information-seeking skills and provide data to fulfill Accreditation Council for Graduate Medical Education competencies.

Highlights

  • The University of Michigan MEDLINE Search Assessment tool can be used to assess search skills in residency education.
  • Five elements were identified as critical elements in the development of an effective MEDLINE search strategy: inclusion of all search concepts, appropriate use of Medical Subject Headings, appropriate use of search limits, successful combination of all concepts, and search efficiency.

Implications

  • This validated assessment tool can serve as an effective means to measure improvements in residents'' information-seeking skills and provide data to fulfill Accreditation Council for Graduate Medical Education competencies.

Question

What to do when a major database ceases publication?

Setting

An urban, academic health sciences library with four campuses serves a university health sciences system, a college of medicine, and five other health sciences colleges.

Methods

Usage statistics of each e-book title in the resource were carefully analyzed. Purchase decisions were made based on the assessment of usage.

Results

Sustainable resources were acquired from other vendors, with perpetual access for library users.

Conclusion

This systematic process of finding alternative resources is an example of librarians'' persistence in acquiring perpetual electronic resources when a major resource is cancelled.  相似文献

Objective

The research attempted to develop search filters for biomedical literature databases that improve retrieval of studies of clinical relevance for the nursing and rehabilitation professions.

Methods

Diagnostic testing framework compared machine-culled and practitioner-nominated search terms with a hand-tagged clinical literature database.

Results

We were unable to: (1) develop filters for nursing, likely because of the overlapping and expanding scope of practice for nurses in comparison with medical professionals, or (2) develop filters for rehabilitation, because of its broad scope and the profession''s multifaceted understanding of “health and ability.”

Conclusions

We found limitations on search filter development for these health professions: nursing and rehabilitation.  相似文献

Objective

The purpose of this study was to investigate the relative effectiveness of three web-scale discovery (WSD) tools in answering health sciences search queries.

Methods

Simple keyword searches, based on topics from six health sciences disciplines, were run at multiple real-world implementations of EBSCO Discovery Service (EDS), Ex Libris''s Primo, and ProQuest''s Summon. Each WSD tool was evaluated in its ability to retrieve relevant results and in its coverage of MEDLINE content.

Results

All WSD tools returned between 50%–60% relevant results. Primo returned a higher number of duplicate results than the other 2 WSD products. Summon results were more relevant when search terms were automatically mapped to controlled vocabulary. EDS indexed the largest number of MEDLINE citations, followed closely by Summon. Additionally, keyword searches in all 3 WSD tools retrieved relevant material that was not found with precision (Medical Subject Headings) searches in MEDLINE.

Conclusions

None of the 3 WSD products studied was overwhelmingly more effective in returning relevant results. While difficult to place the figure of 50%–60% relevance in context, it implies a strong likelihood that the average user would be able to find satisfactory sources on the first page of search results using a rudimentary keyword search. The discovery of additional relevant material beyond that retrieved from MEDLINE indicates WSD tools'' value as a supplement to traditional resources for health sciences researchers.  相似文献

Objective

The authors explored the feasibility and possible benefit of tablet-based educational materials for patients in clinic waiting areas.

Methods

We distributed eight tablets preloaded with diagnosis-relevant information in two clinic waiting areas. Patients were surveyed about satisfaction, usability, and effects on learning. Technical issues were resolved.

Results

Thirty-seven of forty patients completed the survey. On average, the patients were satisfied in all categories.

Conclusions

Placing tablet-based educational materials in clinic waiting areas is relatively easy to implement. Patients using tablets reported satisfaction across three domains: usability, education, and satisfaction.  相似文献

Question:

Can information literacy (IL) be embedded into the curriculum and clinical environment to facilitate patient care and lifelong learning?

Setting:

The Australian School of Advanced Medicine (ASAM) provides competence-based programs incorporating patient-centred care and lifelong learning. ASAM librarians use outcomes-based educational theory to embed and assess IL into ASAM''s educational and clinical environments.

Methods:

A competence-based IL program was developed where learning outcomes were linked to current patients and assessed with checklists. Weekly case presentations included clinicians'' literature search strategies, results, and conclusions. Librarians provided support to clinicians'' literature searches and assessed their presentations using a checklist.

Main Results:

Outcome data showed clinicians'' searching skills improved over time; however, advanced MEDLINE searching remained challenging for some. Recommendations are provided.

Conclusion:

IL learning that takes place in context using measurable outcomes is more meaningful, is enduring, and likely contributes to patient care. Competence-based assessment drives learning in this environment.  相似文献

Objective

The purpose of this study was to compare effectiveness of different options for de-duplicating records retrieved from systematic review searches.

Methods

Using the records from a published systematic review, five de-duplication options were compared. The time taken to de-duplicate in each option and the number of false positives (were deleted but should not have been) and false negatives (should have been deleted but were not) were recorded.

Results

The time for each option varied. The number of positive and false duplicates returned from each option also varied greatly.

Conclusion

The authors recommend different de-duplication options based on the skill level of the searcher and the purpose of de-duplication efforts.  相似文献

Objective

The researchers assessed prevalence in the clinical case report literature of multiple reports independently reporting the same (or nearly the same) main finding.

Methods

Results from forty-five PubMed queries were examined for incidence and features of main findings (“nuggets”) shared in at least four case reports.

Results

The authors found that nuggets are surprisingly prevalent and large in the case report literature, the largest found so far was reported in seventeen articles. In most cases, the main findings of case reports were evident from examining titles alone.

Conclusions

Our curated examples should serve as gold standards for developing specific automated methods for finding nuggets. Nuggets potentially enable finding-based (instead of topic-based) information retrieval.  相似文献

Question:

What is the process of developing a clinical information tool to be embedded in the electronic health record of a very large and diverse academic medical center?

Setting:

The development took place at the University of Pittsburgh Health Sciences Library System.

Method:

The clinical information tool developed is a search box with subject tabs to provide quick access to designated full-text information resources. Each subject tab offers a federated search of a different pool of resources. Search results are organized “on the fly” into meaningful categories using clustering technology and are directly accessible from the results page.

Results:

After more than a year of discussion and planning, a clinical information tool was embedded in the academic medical center''s electronic health record.

Conclusion:

The library successfully developed a clinical information tool, called Clinical-e, for use at the point of care. Future development will refine the tool and evaluate its impact and effectiveness.  相似文献

Background:

Since 2005, International Committee of Medical Journal Editors (ICMJE) member journals have required that clinical trials be registered in publicly available trials registers before they are considered for publication.

Objectives:

The research explores whether it is adequate, when searching to inform systematic reviews, to search for relevant clinical trials using only public trials registers and to identify the optimal search approaches in trials registers.

Methods:

A search was conducted in ClinicalTrials.gov and the International Clinical Trials Registry Platform (ICTRP) for research studies that had been included in eight systematic reviews. Four search approaches (highly sensitive, sensitive, precise, and highly precise) were performed using the basic and advanced interfaces in both resources.

Results:

On average, 84% of studies were not listed in either resource. The largest number of included studies was retrieved in ClinicalTrials.gov and ICTRP when a sensitive search approach was used in the basic interface. The use of the advanced interface maintained or improved sensitivity in 16 of 19 strategies for Clinicaltrials.gov and 8 of 18 for ICTRP. No single search approach was sensitive enough to identify all studies included in the 6 reviews.

Conclusions:

Trials registers cannot yet be relied upon as the sole means to locate trials for systematic reviews. Trials registers lag behind the major bibliographic databases in terms of their search interfaces.

Implications:

For systematic reviews, trials registers and major bibliographic databases should be searched. Trials registers should be searched using sensitive approaches, and both the registers consulted in this study should be searched.Clinical trials registers such as ClinicalTrials.gov and portals to trials registers such as the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) are increasingly used to identify ongoing or completed clinical trials. These resources offer important information on the methods and progress of trials likely to be of interest to a range of users, including researchers, clinicians, and patients. The extent to which these resources can be relied upon as a sole source of trials for inclusion in systematic reviews, including Cochrane systematic reviews (CSRs), is the subject of the research study reported here. This study also investigates the most efficient ways that librarians, information professionals, and other searchers can search these resources. Search efficiency was investigated by evaluating the overlap and unique yield of searches in the two resources and by testing four search approaches. The tested search approaches ranged from the very precise (single specific condition search term combined with a single specific intervention search term) to the very sensitive (at least two interventions terms).  相似文献

Objective

The research investigated topic priorities for data literacy training for biomedical researchers and staff.

Methods

An electronic survey was used to assess researchers'' level of knowledge related to data literacy skills and the relevance of these skills to their work.

Results

Most respondents did not have any formal training in data literacy. Respondents considered most tasks highly relevant to their work but rated their expertise in tasks lower.

Conclusion

Among this group, researchers have diverse data literacy training needs. Librarians'' expertise makes them well suited to provide such training.  相似文献

Purpose

The research assessed a three-year continuing medical education–style program for medical students in a Midwestern academic medical library.

Methods

A mixed methods approach of a survey and two focus groups comparing attendees versus non-attendees assessed the program.

Results

Eleven students participated in the focus groups. Attendance was driven by topic interest and lunch. Barriers included lack of interest, scheduling, location, and convenience.

Conclusions

Although attendance was a challenge, students valued opportunities to learn new skills. This study showcases a reproducible method to engage students outside the curriculum.  相似文献

Objective:

The research assesses the information-seeking behaviors of health sciences faculty, including their use of online databases, journals, and social media.

Methodology:

A survey was designed and distributed via email to 754 health sciences faculty at a large urban research university with 6 health sciences colleges.

Results:

Twenty-six percent (198) of faculty responded. MEDLINE was the primary database utilized, with 78.5% respondents indicating they use the database at least once a week. Compared to MEDLINE, Google was utilized more often on a daily basis. Other databases showed much lower usage.

Conclusions:

Low use of online databases other than MEDLINE, link-out tools to online journals, and online social media and collaboration tools demonstrates a need for meaningful promotion of online resources and informatics literacy instruction for faculty.

Implications:

Library resources are plentiful and perhaps somewhat overwhelming. Librarians need to help faculty discover and utilize the resources and tools that libraries have to offer.  相似文献

Objectives

This study assessed the need to develop a public health informatics (PHI) introductory course and determine contents of such a course.

Methods

Community assessments employing focus group interviews and an online survey were utilized to determine course need and content.

Results

Results revealed a need to provide PHI training to graduate public health students and suggested broad course content requirements. Results indicated lack of awareness of libraries and librarians as sources of public health information.

Conclusions

A graduate PHI course was developed and delivered. Additionally, implementation of a subject guide increased the library''s profile.  相似文献

Purpose

The study evaluated medical students'' familiarity with information literacy and informatics during the health sciences library orientation.

Methods

A survey was fielded at the start of the 2013 school year.

Results

Seventy-two of 77 students (94%) completed the survey. Over one-half (57%) expected to use library research materials and services. About half (43%) expected to use library physical space. Students preferred accessing biomedical research on laptops and learning via online-asynchronous modes.

Conclusions

The library identified areas for service development and outreach to medical students and academic departments.  相似文献

Purpose

The study evaluates how providers give patient education materials and identifies improvements to comply with Meaningful Use (MU) requirements.

Methods

Thirty-eight patient-provider interactions in two health care outpatient clinics were observed.

Results

Providers do not uniformly know MU patient education requirements. Providers have individual preferences and find gaps in what is available. Accessing and documenting patient education varies among providers. Embedded electronic health record (EHR) materials, while available, have technical access barriers.

Conclusions

Providers'' EHR skills and knowledge levels contribute to non-standardized patient education delivery.  相似文献
