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.

Objective:

The research analyzed evaluation data to assess medical student satisfaction with the learning experience when required PubMed training is offered entirely online.

Methods:

A retrospective study analyzed skills assessment scores and student feedback forms from 455 first-year medical students who completed PubMed training either through classroom sessions or an online tutorial. The class of 2006 (n = 99) attended traditional librarian-led sessions in a computer classroom. The classes of 2007 (n = 120), 2008 (n = 121), and 2009 (n = 115) completed the training entirely online through a self-paced tutorial. PubMed skills assessment scores and student feedback about the training were compared for all groups.

Results:

As evidenced by open-ended comments about the training, students who took the online tutorial were equally or more satisfied with the learning experience than students who attended classroom sessions, with the classes of 2008 and 2009 reporting greater satisfaction (P<0.001) than the other 2 groups. The mean score on the PubMed skills assessment (91%) was the same for all groups of students.

Conclusions:

Student satisfaction improved and PubMed assessment scores did not change when instruction was offered online to first-year medical students. Comments from the students who received online training suggest that the increased control and individual engagement with the web-based content led to their satisfaction with the online tutorial.

Highlights

  • First-year medical students at Mount Sinai School of Medicine responded positively to an online PubMed tutorial and skills assessment created by librarians.
  • Students who took the online tutorial passed the PubMed skills assessment at the same high rate as students who attended in-class training led by librarians.
  • Feedback suggests that students preferred the individual control of the web-based content and the ease with which the online training fit into their crowded schedules.

Implications

  • Interactive online training encourages students to direct their own learning experience and can lead to greater student satisfaction.
  • Medical students of the Millennial generation may prefer flexible, self-paced assignments that can be completed at times and locations convenient to them.
  • Medical librarians can create online tutorials to successfully engage and instruct the next generation of medical students.

Background:

Student peer assessment (SPA) has been used intermittently in medical education for more than four decades, particularly in connection with skills training. SPA generally has not been rigorously tested, so medical educators have limited evidence about SPA effectiveness.

Methods:

Experimental design: Seventy-one first-year medical students were stratified by previous test scores into problem-based learning tutorial groups, and then these assigned groups were randomized further into intervention and control groups. All students received evidence-based medicine (EBM) training. Only the intervention group members received SPA training, practice with assessment rubrics, and then application of anonymous SPA to assignments submitted by other members of the intervention group.

Results:

Students in the intervention group had higher mean scores on the formative test with a potential maximum score of 49 points than did students in the control group, 45.7 and 43.5, respectively (P = 0.06).

Conclusions:

SPA training and the application of these skills by the intervention group resulted in higher scores on formative tests compared to those in the control group, a difference approaching statistical significance. The extra effort expended by librarians, other personnel, and medical students must be factored into the decision to use SPA in any specific educational context.

Implications:

SPA has not been rigorously tested, particularly in medical education. Future, similarly rigorous studies could further validate use of SPA so that librarians can optimally make use of limited contact time for information skills training in medical school curricula.  相似文献

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.

Objectives:

The research evaluated participant satisfaction with the content and format of the “Web 2.0 101: Introduction to Second Generation Web Tools” course and measured the impact of the course on participants'' self-evaluated knowledge of Web 2.0 tools.

Methods:

The “Web 2.0 101” online course was based loosely on the Learning 2.0 model. Content was provided through a course blog and covered a wide range of Web 2.0 tools. All Medical Library Association members were invited to participate. Participants were asked to complete a post-course survey. Respondents who completed the entire course or who completed part of the course self-evaluated their knowledge of nine social software tools and concepts prior to and after the course using a Likert scale. Additional qualitative information about course strengths and weaknesses was also gathered.

Results:

Respondents'' self-ratings showed a significant change in perceived knowledge for each tool, using a matched pair Wilcoxon signed rank analysis (P<0.0001 for each tool/concept). Overall satisfaction with the course appeared high. Hands-on exercises were the most frequently identified strength of the course; the length and time-consuming nature of the course were considered weaknesses by some.

Conclusion:

Learning 2.0-style courses, though demanding time and self-motivation from participants, can increase knowledge of Web 2.0 tools.

Highlights

  • Course participants'' knowledge of Web 2.0 tools increased significantly.
  • Medical Library Association members liked the online course format, particularly the hands-on exercises and self-pacing.
  • There was no significant difference in course completion rate or course satisfaction among participants from academic, hospital, or other library settings.
  • Few survey respondents pointed specifically to workplace technology blocking as a reason for non-completion, though this underestimates the effect of such blocking on hospital and corporate library staff.

Implications

  • MLA members appreciate having online continuing education (CE) courses. New short, online CE courses were developed based on the findings of this survey.
  • Hands-on exercises may improve learning and increase motivation.
  • Time and self-motivation are necessary for completing online courses.

Objectives:

The research identified the publication types and ages most frequently cited in the infectious diseases literature and the most commonly cited journals.

Methods:

From 2008–2010, 5,056 articles in 5 infectious diseases journals cited 166,650 items. Two random samples were drawn: one (n = 1,060) from the total set of citations and one (n = 1,060) from the citations to journal articles. For each sample citation, publication type and date, age of cited item, and inclusion of uniform resource locator (URL) were collected. For each item in the cited journal articles sample, journal title, publication date, and age of the cited article were collected. Bradford zones were used for further analysis.

Results:

Journal articles (91%, n = 963) made up the bulk of cited items, followed by miscellaneous items (4.6%, n = 49). Dates of publication for cited items ranged from 1933–2010 (mean = 2001, mode = 2007). Over half (50.2%, n = 483) of cited journal articles were published within the previous 5 years. The journal article citations included 358 unique journal titles.

Discussion:

The citations to current and older publications in a range of disciplines, heavy citation of journals, and citation of miscellaneous and government documents revealed the depth and breadth of resources needed for the study of infectious diseases.

Highlights

  • Literature on infectious diseases is multidisciplinary, encompassing medical specialties, public health, and the medical sciences.
  • Infectious disease publications cite journal articles more than 90% of the time. Cited journal articles greatly range in age at citation: more than a quarter were over 10 years old.
  • Infectious disease citation patterns resemble clinical medicine citation patterns more than public health citation patterns.

Implications

  • Infectious disease professionals need access to general medicine titles as well as infectious disease, immunology, virology, microbiology, and public health literature.
  • Librarians serving infectious disease researchers and practitioners should provide access to older materials, especially journal back files, to support the cyclical needs of their patrons.

Objective:

This paper describes the Lamar Soutter Library''s process and costs associated with digitizing 300 doctoral dissertations for a newly implemented institutional repository at the University of Massachusetts Medical School.

Methodology:

Project tasks included identifying metadata elements, obtaining and tracking permissions, converting the dissertations to an electronic format, and coordinating workflow between library departments. Each dissertation was scanned, reviewed for quality control, enhanced with a table of contents, processed through an optical character recognition function, and added to the institutional repository.

Results:

Three hundred and twenty dissertations were digitized and added to the repository for a cost of $23,562, or $0.28 per page. Seventy-four percent of the authors who were contacted (n = 282) granted permission to digitize their dissertations. Processing time per title was 170 minutes, for a total processing time of 906 hours. In the first 17 months, full-text dissertations in the collection were downloaded 17,555 times.

Conclusion:

Locally digitizing dissertations or other scholarly works for inclusion in institutional repositories can be cost effective, especially if small, defined projects are chosen. A successful project serves as an excellent recruitment strategy for the institutional repository and helps libraries build new relationships. Challenges include workflow, cost, policy development, and copyright permissions.

Highlights

  • The Lamar Soutter Library partnered with the University of Massachusetts Medical School Graduate School of Biomedical Sciences to digitize doctoral dissertations for inclusion in a newly created institutional repository.
  • Seventy-four percent of dissertation authors (209/282) gave permission for the digitization. The cost to process the entire dissertation collection in-house was $23,562, only $1,062 more than the estimate to outsource.
  • Digitizing the dissertation collection increased access: the print collection was used 723 times in the past 5 years, while the electronic collection was used 17,555 times in 17 months.

Implications

  • Digitizing student works is an effective way to begin populating an institutional repository.
  • In-house digitization projects can be cost-competitive with outsourced alternatives.
  • A repository can be a catalyst for developing relationships in the institution by providing the library with a new avenue for outreach.
  • Skills and experience gained from a small project can be applied to larger-scale projects.

Objectives:

Through interviews with the National Library of Medicine''s MedlinePlus Go Local collaborators, an evaluation team sought to identify process characteristics that are critical for long-term sustainability of Go Local projects and to describe the impact that Go Local projects have on sponsoring institutions.

Methods:

Go Local project coordinators (n = 44) at 31 sponsor institutions participated in semi-structured interviews about their experiences developing and maintaining Go Local sites. Interviews were summarized, checked for accuracy by the participating librarians, and analyzed using a general inductive methodology.

Results:

Institutional factors that support Go Local projects were identified through the interviews, as well as strategies for staffing and partnerships with external organizations. Positive outcomes for sponsoring institutions also were identified.

Conclusions:

The findings may influence the National Library of Medicine team''s decisions about improvements to its Go Local system and the support it provides to sponsoring institutions. The findings may benefit current sponsoring institutions as well as those considering or planning a Go Local project.

Highlights

  • Many project coordinators said they underestimated the level of work their National Library of Medicine (NLM) MedlinePlus Go Local projects would require, but most expressed dedication to the project and optimism about project sustainability.
  • An institutional record of community service or outreach and a director who was supportive of the project were important factors in the progress and sustainability of Go Local projects.
  • Go Local projects brought recognition to some sponsoring institutions from their parent institutions or their communities and provided opportunities to establish better relations with other libraries and institutions.
  • Go Local projects ran more smoothly when a person, even a temporary hire, with dedicated time for the project was in charge during the initial building phase. Volunteer assistance has been difficult to motivate and sustain.

Implications

  • NLM''s Go Local proposal guidelines accurately identify the factors that institutions should pay close attention to when planning a Go Local project.
  • NLM should emphasize continuity plans to address project coordinator turnover.
  • NLM should develop a more formal orientation plan for new project coordinators to assist program continuity at the sponsoring institutions.

Objective:

This paper presents the methods and results of a study designed to produce the third edition of the “Basic List of Veterinary Medical Serials,” which was established by the Veterinary Medical Libraries Section in 1976 and last updated in 1986.

Methods:

A set of 238 titles were evaluated using a decision matrix in order to systematically assign points for both objective and subjective criteria and determine an overall score for each journal. Criteria included: coverage in four major indexes, scholarly impact rank as tracked in two sources, identification as a recommended journal in preparing for specialty board examinations, and a veterinary librarian survey rating.

Results:

Of the 238 titles considered, a minimum scoring threshold determined the 123 (52%) journals that constituted the final list. The 36 subject categories represented on the list include general and specialty disciplines in veterinary medicine. A ranked list of journals and a list by subject category were produced.

Conclusion:

Serials appearing on the third edition of the “Basic List of Veterinary Medical Serials” met expanded objective measures of quality and impact as well as subjective perceptions of value by both librarians and veterinary practitioners.

Highlights

  • The 123 journals on the “Basic List of Veterinary Medical Serials” include 117 journals with a decision matrix score of 15 points or higher, with an additional 6 journals included for more complete subject representation.
  • Subject categories with the greatest number of journals are internal medicine, food animal medicine, and research.
  • Updates for the third edition of the “Basic List” include 59 new titles and 13 new subject categories.

Implications

  • The third edition of the “Basic List” provides a useful collection development and assessment tool for veterinary libraries, as well as general libraries with a need to develop a core collection of veterinary resources.
  • The decision matrix approach, using standard quantitative and focused qualitative measures, provides a useful methodology for creating core lists in other disciplines.

Purpose:

The authors conducted a survey examining (1) the current state of evidence-based medicine (EBM) curricula in US and Canadian medical schools and corresponding learning objectives, (2) medical educators'' and librarians'' participation in EBM training, and (3) barriers to EBM training.

Methods:

A survey instrument with thirty-four closed and open-ended questions was sent to curricular deans at US and Canadian medical schools. The survey sought information on enrollment and class size; EBM learning objectives, curricular activities, and assessment approaches by year of training; EBM faculty; EBM tools; barriers to implementing EBM curricula and possible ways to overcome them; and innovative approaches to EBM education. Both qualitative and quantitative methods were used for data analysis. Measurable learning objectives were categorized using Bloom''s taxonomy.

Results:

One hundred fifteen medical schools (77.2%) responded. Over half (53%) of the 900 reported learning objectives were measurable. Knowledge application was the predominant category from Bloom''s categories. Most schools integrated EBM into other curricular activities; activities and formal assessment decreased significantly with advanced training. EBM faculty consisted primarily of clinicians, followed by basic scientists and librarians. Various EBM tools were used, with PubMed and the Cochrane database most frequently cited. Lack of time in curricula was rated the most significant barrier. National agreement on required EBM competencies was an extremely helpful factor. Few schools shared innovative approaches.

Conclusions:

Schools need help in overcoming barriers related to EBM curriculum development, implementation, and assessment.

Implications:

Findings can provide a starting point for discussion to develop a standardized competency framework.  相似文献

Objective:

The objective of this study was to analyze bibliometric data from ISI, National Institutes of Health (NIH)–funding data, and faculty size information for Association of American Medical Colleges (AAMC) member schools during 1997 to 2007 to assess research productivity and impact.

Methods:

This study gathered and synthesized 10 metrics for almost all AAMC medical schools (n = 123): (1) total number of published articles per medical school, (2) total number of citations to published articles per medical school, (3) average number of citations per article, (4) institutional impact indices, (5) institutional percentages of articles with zero citations, (6) annual average number of faculty per medical school, (7) total amount of NIH funding per medical school, (8) average amount of NIH grant money awarded per faculty member, (9) average number of articles per faculty member, and (10) average number of citations per faculty member. Using principal components analysis, the author calculated the relationships between measures, if they existed.

Results:

Principal components analysis revealed 3 major clusters of variables that accounted for 91% of the total variance: (1) institutional research productivity, (2) research influence or impact, and (3) individual faculty research productivity. Depending on the variables in each cluster, medical school research may be appropriately evaluated in a more nuanced way. Significant correlations exist between extracted factors, indicating an interrelatedness of all variables. Total NIH funding may relate more strongly to the quality of the research than the quantity of the research. The elimination of medical schools with outliers in 1 or more indicators (n = 20) altered the analysis considerably.

Conclusions:

Though popular, ordinal rankings cannot adequately describe the multidimensional nature of a medical school''s research productivity and impact. This study provides statistics that can be used in conjunction with other sound methodologies to provide a more authentic view of a medical school''s research. The large variance of the collected data suggests that refining bibliometric data by discipline, peer groups, or journal information may provide a more precise assessment.

Highlights

  • Principal components analysis discovered three clusters of variables: (1) institutional research productivity, (2) research influence or impact, and (3) individual faculty research productivity.
  • The associations between size-independent measures (e.g., average number of citations/article) were more significant than associations between size-independent bibliometric measures and size-dependent (e.g., number of faculty) bibliometric measures and vice versa, except in the case of total National Institutes of Health (NIH) funding.
  • The factor coefficients, or loadings, for total NIH funding may associate more with the quality of research rather than the quantity of research.
  • The removal of twenty outliers, fourteen highly productive or influential medical schools and six medical schools with relatively low research profiles, changed the results of the analysis significantly.
  • This study''s broad institutional bibliometric data sets cannot be extrapolated to specific departments at the studied medical schools.

Implications

  • Librarians, administrators, and faculty should use several methodologies in tandem with bibliometric data when evaluating institutions'' research impact and productivity.
  • Health sciences librarians should not make use of university rankings materials lacking strong methodological foundations.
  • This study''s bibliometric data may provide a starting point or point of comparison for future assessments.

Objective:

The research studied the status of hospital librarians and library services to better inform the Medical Library Association''s advocacy activities.

Methods:

The Vital Pathways Survey Subcommittee of the Task Force on Vital Pathways for Hospital Librarians distributed a web-based survey to hospital librarians and academic health sciences library directors. The survey results were compared to data collected in a 1989 survey of hospital libraries by the American Hospital Association in order to identify any trends in hospital libraries, roles of librarians, and library services. A web-based hospital library report form based on the survey questions was also developed to more quickly identify changes in the status of hospital libraries on an ongoing basis.

Results:

The greatest change in library services between 1989 and 2005/06 was in the area of access to information, with 40% more of the respondents providing access to commercial online services, 100% more providing access to Internet resources, and 28% more providing training in database searching and use of information resources. Twenty-nine percent (n = 587) of the 2005/06 respondents reported a decrease in staff over the last 5 years.

Conclusions:

Survey data support reported trends of consolidation of hospitals and hospital libraries and additions of new services. These services have likely required librarians to acquire new skills. It is hoped that future surveys will be undertaken to continue to study these trends.

Highlights

  • Data support reported trends in the decrease in the number of hospitals and hospital libraries.
  • About 44.0% of hospitals had some level of onsite library service in 1989, compared with between 33.5% and 29.1% of hospitals in 2005/06.
  • More electronic services and resources, such as Internet access and online materials, are being offered by hospital libraries, in addition to more traditional services
  • Library staffing appears to be more unstable today than in 1989, with more libraries reporting a decrease in the number of staff.

Implications

  • Hospital libraries continue to change in response to changes in the health care environment as health care administrators respond to financial pressures, library staff are downsized, degreed librarian positions are eliminated, and reporting structures change.
  • MLA must continue to track the status of hospital librarians and libraries in light of the changing environment with surveys and other means, in partnership with others such as the National Network of Libraries of Medicine.

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 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.
