Objective:

The research sought to establish a rubric for evaluating evidence-based medicine (EBM) point-of-care tools in a health sciences library.

Methods:

The authors searched the literature for EBM tool evaluations and found that most previous reviews were designed to evaluate the ability of an EBM tool to answer a clinical question. The researchers'' goal was to develop and complete rubrics for assessing these tools based on criteria for a general evaluation of tools (reviewing content, search options, quality control, and grading) and criteria for an evaluation of clinical summaries (searching tools for treatments of common diagnoses and evaluating summaries for quality control).

Results:

Differences between EBM tools'' options, content coverage, and usability were minimal. However, the products'' methods for locating and grading evidence varied widely in transparency and process.

Conclusions:

As EBM tools are constantly updating and evolving, evaluation of these tools needs to be conducted frequently. Standards for evaluating EBM tools need to be established, with one method being the use of objective rubrics. In addition, EBM tools need to provide more information about authorship, reviewers, methods for evidence collection, and grading system employed.

Highlights

  • Eleven of the fourteen previous evidence-based medicine (EBM) tool evaluations were based on clinicians evaluating tools based on their perception of the products'' ability to answer a clinical question.
  • EBM tools'' evidence summaries are not updated as often as products claim.
  • Although many EBM tools claim to be evidence based, only 74% of the 70 evaluated treatment summaries included graded evidence.

Implications

  • To offer the best tools for users, medical libraries should evaluate EBM resources regularly, including the quality of the evidence provided.
  • Medical librarians have a role to play in evaluating the quality of EBM products and can develop assessment tools to aid in this evaluation.

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

Objectives:

This study examined the information-seeking behaviors of basic science researchers to inform the development of customized library services.

Methods:

A qualitative study using semi-structured interviews was conducted on a sample of basic science researchers employed at a university medical school.

Results:

The basic science researchers used a variety of information resources ranging from popular Internet search engines to highly technical databases. They generally relied on basic keyword searching, using the simplest interface of a database or search engine. They were highly collegial, interacting primarily with coworkers in their laboratories and colleagues employed at other institutions. They made little use of traditional library services and instead performed many traditional library functions internally.

Conclusions:

Although the basic science researchers expressed a positive attitude toward the library, they did not view its resources or services as integral to their work. To maximize their use by researchers, library resources must be accessible via departmental websites. Use of library services may be increased by cultivating relationships with key departmental administrative personnel. Despite their self-sufficiency, subjects expressed a desire for centralized information about ongoing research on campus and shared resources, suggesting a role for the library in creating and managing an institutional repository.

Highlights

  • Basic science researchers rely on a small network of individuals in their institution and at other institutions to satisfy their information needs.
  • Basic science researchers tend to ignore institutional boundaries when searching for information and do not necessarily view the library as the primary source of scholarly information.
  • Basic science researchers use the interlibrary loan service regularly but otherwise rarely use traditional library services such as mediated literature searching and instruction.

Implications

  • The library must establish a presence in researchers'' work environments, rather than expect them to seek out library resources and services.
  • The increased emphasis by funding agencies on clinical translational science may impact the information needs of basic science researchers in the future.
  • Libraries have an opportunity to capitalize on their positive reputation and basic scientists'' desire for more centralized information to create new information resources and services such as institutional repositories.

Objective:

The research identified the skills, if any, that health preprofessional students wished to develop after receiving feedback on skill gaps as well as any strategies they intended to use to address these gaps.

Methods:

A qualitative approach was used to elicit students'' reflections on building health information literacy skills. First, the students took the Research Readiness Self-Assessment instrument, which measured their health information literacy, and then they received individually tailored feedback about their scores and skill gaps. Second, students completed a post-assessment survey asking how they intended to close identified gaps in their skills on these. Three trained coders analyzed qualitative comments by 181 students and grouped them into themes relating to “what skills to improve” and “how to improve them.”

Results:

Students intended to develop library skills (64% of respondents), Internet skills (63%), and information evaluation skills (63%). Most students reported that they would use library staff members'' assistance (55%), but even more respondents (82%) planned to learn the skills by practicing on their own. Getting help from librarians was a much more popular learning strategy than getting assistance from peers (20%) or professors (17%).

Conclusions:

The study highlighted the importance of providing health preprofessional students with resources to improve skills on their own, remote access to library staff members, and instruction on the complexity of building health literacy skills, while also building relationships among students, librarians, and faculty.

Highlights

  • After receiving feedback on skill gaps, most preprofessional health students intend to develop their information literacy skills.
  • Some students report that a trip to the library is a barrier to using library resources.
  • Students see the need to build their information evaluation skills, knowledge of citations and plagiarism, and library skills, which they differentiate from Internet skills.
  • Students are more likely to identify librarians as sources for assistance in finding information than faculty or peers after receiving individual feedback explaining the role of libraries and library staff members.

Implications

  • Students'' health information competencies can be built through assessment and feedback that reveals skill gaps, highlights misconceptions, and offers ideas on how to improve.
  • Access to professionally designed self-study resources is needed for students who intend to develop health information competencies on their own.

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.

Objectives:

This study sought to ascertain the publication rate of abstracts presented at the annual meetings of the Medical Library Association (MLA) for the years of 2002 and 2003. The secondary objectives were to examine possible reasons for non-publication and factors influencing publication.

Methods:

A total of 442 abstracts from both meeting years, consisting of presented papers and posters, were examined. The 2 methods used to obtain a publication rate were literature searches and an online questionnaire sent to first authors. The questionnaire also asked abstract authors about reasons for non-publication and other factors that might have influenced their decisions about whether or not to submit the project for publication.

Results:

The overall publication rate from the survey was 26.5%, and the publication rate found via literature searching was 27.6%. The most common reason given for non-publication was time restrictions. Also notable was the large proportion of abstracts written by librarians working at universities and those having 25 or more years in the library profession.

Discussion:

Publication rates for abstracts presented at the Medical Library Association meetings for the years studied rank at the low end in comparison with other medical professional associations. Further research into factors affecting publication may reveal ways to increase this rate.

Highlights

  • Publication rates from posters and presentations at the Medical Library Association''s 2002 and 2003 annual meetings were estimated at less than 28.0% using data from an author survey and literature search. In contrast, a Cochrane systematic review of 79 similar biomedical research studies found a mean publication rate of 44.5%.
  • Respondents listed time restrictions as their primary reason for not submitting their presentations for publication.

Implications

  • Compared to biomedical conferences, relatively little of the information presented at Medical Library Association annual meetings is available as peer-reviewed evidence in the published literature.
  • Each profession has different norms for the nature and style of information in presentations at meetings. The further presenters get from basic research, the more difficult it may be for them to conceptualize a presentation as a formal paper. Diverse publication rates between professions are likely to remain.
  • Additional study could be aimed at further clarifying the reasons for non-publication and possible means to ameliorate them.

Background:

To encourage evidence-based practice, an Annals of Internal Medicine editorial called for a new professional on clinical teams: an informationist trained in science or medicine as well as information science.

Objectives:

The study explored the effects of informationists on information behaviors of clinical research teams, specifically, frequency of seeking information for clinical or research decisions, range of resources consulted, perceptions about access to information, confidence in adequacy of literature searches, and effects on decision making and practice. It also explored perceptions about training and experience needed for successful informationists.

Methods:

Exploratory focus groups and key interviews were followed by baseline and follow-up surveys conducted with researchers and clinicians receiving the service. Survey data were analyzed with Pearson''s chi-square or Fisher''s exact test.

Results:

Comparing 2006 to 2004 survey responses, the researchers found that study participants reported: seeking answers to questions more frequently, spending more time seeking or using information, believing time was less of an obstacle to finding or using information, using more information resources, and feeling greater satisfaction with their ability to find answers. Participants'' opinions on informationists'' qualifications evolved to include both subject knowledge and information searching expertise.

Conclusion:

Over time, clinical research teams with informationists demonstrated changes in their information behaviors, and they valued an informationist''s subject matter expertise more.

Highlights

  • Informationist involvement in traditional team activities—going on rounds and searching and critically evaluating the literature—increased over time.
  • As the relationship between a clinical team and informationist developed, activities expanded to include projects such as development of wikis, databases, and websites.
  • Clinical teams came to view subject knowledge as key to an informationist''s preparation; however, their expertise as information scientists was valued most highly.
  • “Initiative,” approaching research staff in their workplace, was the one personal trait focus group participants agreed on as most desirable for an informationist.
  • When first introduced to the concept, researchers cited customization of services to team needs as a major benefit.

Implications

  • To assure a successful informationist program, libraries must be prepared to commit time and money.
  • Whether informationists or not, librarians should be prepared to support users'' increased need for genetics and molecular biology information.

Objectives:

The research objectives were to (1) describe the current and future roles of hospital librarians and the challenges they face and (2) find evidence supporting the hypothesis that librarians are essential to hospitals in achieving the organizations'' mission-critical goals.

Method:

The authors used results from a previous research study that identified the five organizational mission-critical goals important to hospital administrators and then searched the literature and solicited examples from hospital librarians to describe the librarian''s role in helping hospitals achieve these goals.

Results:

The literature supports the hypothesis that hospital librarians play important roles in the success of the hospital. Librarians support quality clinical care, efficient and effective hospital operations, continuing education for staff, research and innovation, and patient, family, and community health information needs.

Conclusion:

Hospital librarians fulfill many mission-critical roles in today''s hospital, providing the right information at the right time in a variety of ways to enhance hospital and medical staff effectiveness, optimize patient care, improve patient outcomes, and increase patient and family satisfaction with the hospital and its services. Because hospital librarians and their services provide an excellent return on investment for the hospital and help the hospital keep its competitive edge, hospital staff should have access to the services of a professional librarian.

Highlights

  • A review of the literature supports the hypothesis that services of the professional librarian result in:
    • enhanced staff effectiveness,
    • optimized patient care,
    • improved patient outcomes, and
    • increased patient and family satisfaction with the hospital and its services.

Implications

  • Because hospital librarians and their services provide an excellent return on investment for the hospital and help the hospital keep its competitive edge, hospital staff should have access to the services of a professional librarian.

Objectives:

The research determined (1) the information sources that family physicians (FPs) most commonly use to update their general medical knowledge and to make specific clinical decisions, and (2) the information sources FPs found to be most physically accessible, intellectually accessible (easy to understand), reliable (trustworthy), and relevant to their needs.

Methods:

A cross-sectional postal survey of 792 FPs and locum tenens, in full-time or part-time medical practice, currently practicing or on leave of absence in the Canadian province of Saskatchewan was conducted during the period of January to April 2008.

Results:

Of 666 eligible physicians, 331 completed and returned surveys, resulting in a response rate of 49.7% (331/666). Medical textbooks and colleagues in the main patient care setting were the top 2 sources for the purpose of making specific clinical decisions. Medical textbooks were most frequently considered by FPs to be reliable (trustworthy), and colleagues in the main patient care setting were most physically accessible (easy to access).

Conclusions:

When making specific clinical decisions, FPs were most likely to use information from sources that they considered to be reliable and generally physically accessible, suggesting that FPs can best be supported by facilitating easy and convenient access to high-quality information.

Highlights

  • Medical textbooks were the most popular information source for family physicians'' (FPs'') clinical decision-making purposes, and medical journals were the most popular information source for the purpose of updating FPs'' general medical knowledge.
  • FPs considered medical textbooks to be the most reliable (trustworthy) source, colleagues the most physically accessible, and continuing medical education the most relevant and intellectually accessible.
  • The lowest ranked information sources across all four attributes were personal digital assistants, mental health professionals, pharmaceutical sales representatives, and other decision aids.

Implications

  • The most popular information sources for clinical decision-making purposes among FPs were sources characterized as reliable and generally physically accessible.
  • This study suggests the need for further research into interventions that target information access barriers in FPs'' practice settings and the promotion of reliable evidence for FPs'' clinical decision-making purposes.

Purpose:

A systematic literature review was conducted to synthesize what is known about informationists, highlight program models, and suggest areas for future research.

Methods:

Articles retrieved through database searching were reviewed for relevance. Informationist case reports were identified and coded according to an attributes checklist. Data from other retained publications were synthesized under broad themes. The few research studies found were reviewed for level of evidence.

Results:

Of 113 papers reviewed, the study identified 7 classic and 8 emerging informationist programs. Two major models are apparent, clinical and research, with priorities differing according to program maturity. The literature synthesis also brought together current thinking about informationist qualifications; practice roles; setting characteristics; education and training; organizational, programmatic, and service provider success factors; and challenges and barriers. Program outcomes to date are reported, and future research topics suggested. Specific findings will assist informationist program planners.

Conclusions:

While the informationist concept remains in the early adopter stage, it appears that domain knowledge, continuous learning, and embedding (working in context) are essential to success. The need for librarians to transition to greater specialization and libraries to emphasize customized service was underscored. A research agenda focused on information management, dissemination, behaviors, and economics is proposed.

Highlights

  • After years of emphasizing the generalist librarian, health sciences librarians must become more specialized, paralleling the health care environment in which they work.
  • An embedded informationist is more likely to achieve credibility, acceptance, and sustainability than an impersonal information service provided at a distance.
  • Subject expertise is essential for the informationist.
  • Model informationist programs with the greatest stability are library funded.
  • Because informationist programs are inherently targeted to small groups, multisite studies are necessary to achieve robust evaluation.

Implications

  • A library starting an informationist program should review existing models, identify local needs, set program objectives, and then select the most appropriate approaches for its users.
  • Programmatic emphasis should be placed on both technical and service excellence.
  • Organizational commitment is needed for knowledge integration into practice and for the informationists'' lifelong learning.

Objectives:

The research sought to determine if first-year medical students consulted and cited resources specifically highlighted during library instructional sessions.

Methods:

Students attended a library resources instructional session. Resources that pertained to the students'' assignment were demonstrated and discussed. The students created a report including citations from relevant literature. The citations were analyzed and categorized as: a resource discussed at the instructional session, a resource found on the course LibGuide, a library resource, course material, or some other resource. All citations were subcategorized as print or electronic.

Results:

Three years (2008–2011) of data analyzing 2,983 citations showed that 49.55% of all citations were from resources discussed during library instructional sessions; 21.86% came from resources with links on the course LibGuide; 77.51% were from library resources; and 90.68% came from electronic resources.

Conclusion:

Students cited resources specifically highlighted during library instructional sessions for their assignments. The percentage of all citations coming from resources highlighted during the instructional sessions or found on the course LibGuide indicates that library instruction had an impact on the students'' work.

Highlights

  • Review of the literature shows that instruction about library resources accompanied by clear guidelines on scholarly research methods and resources provided by course instructors have the biggest impact on the quality of cited materials in student bibliographies.
  • Graduate medical students cited library resources more frequently than nonlibrary resources for their assigned coursework.
  • Graduate medical students cited materials and resources specifically highlighted during library instructional sessions for their assigned coursework.

Implications

  • Instruction about library resources tailored to medical students'' assignments impacts the resources that the students consult and cite for their assignments.
  • Using the information gathered from citation analysis to modify teaching plans can impact the effectiveness of library instructional sessions.

Objective:

The research tested the accuracy of the VIVO Harvester software in identifying publications authored by faculty members affiliated with a National Institutes of Health Clinical and Translational Sciences Award (CTSA) site.

Methods:

Health sciences librarians created “gold standard” lists of references for the years 2001 to 2011 from PubMed for twenty-five randomly selected investigators from one CTSA site. These gold standard lists were compared to the same twenty-five investigators'' reference lists produced by VIVO Harvester. The authors subjected the discrepancies between the lists to sensitivity and specificity analyses.

Results:

The VIVO Harvester correctly identified only about 65% of the total eligible PubMed references for the years 2001–2011 for the CTSA-affiliated investigators. The identified references produced by VIVO Harvester were precise yet incomplete. The sensitivity rate was 0.65, and the specificity rate was 1.00.

Conclusion:

While the references produced by VIVO Harvester could be confirmed in PubMed, the VIVO Harvester retrieved only two-thirds of the required references from PubMed. National Institutes of Health CTSA sites will need to supplement VIVO Harvester–produced references with the expert searching skills of health sciences librarians.

Implications:

Health sciences librarians with searching skills need to alert their CTSA sites about these deficiencies and offer their skills to advance their sites'' missions.  相似文献

Objectives:

The study updates Schloman''s 1997 study, “Mapping the Literature of Health Education.” The authors identify an updated list of core health education journals and determine the coverage of these journals by electronic indexes.

Methods:

Citations from four source journals for the years 2006 to 2008 were analyzed using the established methodology of the “Mapping the Literature of Allied Health Project.” The cited journals were divided into three zones of productivity by using Bradford''s Law of Scattering.

Results:

There were 19,907 citations in 602 source articles. Journal articles were the most commonly cited format type. Of the 1,896 journal titles cited, 20 (1.1%) made up the core journals. Together, the fields of medicine, health education, and psychology accounted for 85.0% of the journals in the core. Self-citation was found to be a common practice in the source journals. Scopus had the broadest journal coverage of the indexes examined.

Conclusions:

The results of this study provide a new picture of the health education literature: The volume has grown significantly, cites older materials, and relies less on sexual health journals and more on psychology journals.

Highlights

  • Three of the four health education journals in this study showed a statistically significant increase in the number of journal articles published since 1993.
  • The majority of core journals in the field are from medicine (35.0%), health education (30.0%), and psychology (20.0%), with the largest change in core journal make-up being an increase in psychology journals.
  • Scopus provided the most thorough coverage of the cited journals, followed by MEDLINE, Social Sciences Citation Index, and CINAHL Plus with Full Text.

Implications

  • Reference librarians should instruct users on more sophisticated ways to manage the growing volume of the health education literature.
  • Collection development librarians may need to purchase and retain older materials to support health education research.
  • Librarians should purchase and direct patrons to a variety of databases to completely cover the literature of medicine, health education, and psychology.

Objective:

This paper examines the development and evaluation of an automatic summarization system in the domain of molecular genetics. The system is a potential component of an advanced biomedical information management application called Semantic MEDLINE and could assist librarians in developing secondary databases of genetic information extracted from the primary literature.

Methods:

An existing summarization system was modified for identifying biomedical text relevant to the genetic etiology of disease. The summarization system was evaluated on the task of identifying data describing genes associated with bladder cancer in MEDLINE citations. A gold standard was produced using records from Genetics Home Reference and Online Mendelian Inheritance in Man. Genes in text found by the system were compared to the gold standard. Recall, precision, and F-measure were calculated.

Results:

The system achieved recall of 46%, and precision of 88% (F-measure = 0.61) by taking Gene References into Function (GeneRIFs) into account.

Conclusion:

The new summarization schema for genetic etiology has potential as a component in Semantic MEDLINE to support the work of data curators.

Highlights

  • Semantic MEDLINE streamlines information retrieval by succinctly expressing the meaning of sometimes complicated text and summarizing output according to a user''s needs.
  • Semantic MEDLINE identifies genes noted in biomedical text as associated with a disease process.
  • Semantic MEDLINE can potentially simplify secondary database curation.

Implications

  • Library information retrieval services can potentially benefit from automated applications such as Semantic MEDLINE.
  • Use of such automated applications can facilitate the library''s work in interdepartmental collaborative endeavors, thus reinforcing the library''s core value in its parent institution.
