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.

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:

Evidence-based practice (EBP) provides nurses with a method to use critically appraised and scientifically proven evidence for delivering quality health care to a specific population. The objective of this study was to explore nurses'' awareness of, knowledge of, and attitude toward EBP and factors likely to encourage or create barriers to adoption. In addition, information sources used by nurses and their literature searching skills were also investigated.

Method:

A total of 2,100 copies of the questionnaire were distributed to registered nurses in 2 public hospitals in Singapore, and 1,486 completed forms were returned, resulting in a response rate of 70.8%.

Results:

More than 64% of the nurses expressed a positive attitude toward EBP. However, they pointed out that due to heavy workload, they cannot keep up to date with new evidence. Regarding self-efficacy of EBP-related abilities, the nurses perceived themselves to possess moderate levels of skills. The nurses also felt that EBP training, time availability, and mentoring by nurses with EBP experience would encourage them to implement EBP. The top three barriers to adopting EBP were lack of time, inability to understand statistical terms, and inadequate understanding of the jargon used in research articles. For literature searching, nurses were using basic search features and less than one-quarter of them were familiar with Boolean and proximity operators.

Conclusion:

Although nurses showed a positive attitude toward EBP, certain barriers were hindering their smooth adoption. It is, therefore, desirable that hospital management in Southeast Asia, particularly in Singapore, develop a comprehensive strategy for building EBP competencies through proper training. Moreover, hospital libraries should also play an active role in developing adequate information literacy skills among the nurses.

Highlights

  • Nurses in Singapore, as in other countries, support the idea of evidence-based practice (EBP) but have limited skills in the area of literature searching and understanding evidence, which limits their use of evidence-based practice.
  • Only a small number of nurses were able to pick an appropriate search strategy for a given topic, indicating a lack of basic literature searching skills.
  • Sufficient literature searching knowledge is essential to retrieve current, relevant, and accurate evidence. However, a majority of nurses do not know how to properly use Boolean and proximity operators, indexing, truncation, or limits.

Implications

  • Librarians need to be part of providing ongoing training for clinical nurses in searching the evidence, especially in hospitals promoting EBP or seeking Magnet status.
  • Training is needed for clinical nurses to be able to achieve the use of EBP, and librarians can support this goal by teaching the search strategies portion of an EBP skills course.
  • This study''s instrument could be used by librarians as a needs assessment tool to measure their own clinical nurses'' information literacy skills, if justification is needed locally.

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.

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:

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.

Objectives:

The Medical Library Association (MLA)/National Library of Medicine (NLM) Joint Electronic Personal Health Record Task Force examined the current state of personal health records (PHRs).

Methods:

A working definition of PHRs was formulated, and a database was built with fields for specified PHR characteristics. PHRs were identified and listed. Each task force member was assigned a portion of the list for data gathering. Findings were recorded in the database.

Results:

Of the 117 PHRs identified, 91 were viable. Almost half were standalone products. A number used national standards for nomenclature and/or record structure. Less than half were mobile device enabled. Some were publicly available, and others were offered only to enrollees of particular health plans or employees at particular institutions. A few were targeted to special health conditions.

Conclusions:

The PHR field is very dynamic. While most PHR products have some common elements, their features can vary. PHRs can link their users with librarians and information resources. MLA and NLM have taken an active role in making this connection and in encouraging librarians to assume this assistance role with PHRs.

Highlights

  • A variety of personal health records (PHRs) exist with some tied to medical health records and others offered as standalone products.
  • Librarians can be connected to PHR users through inclusion of an assistance statement in PHRs.
  • PHRs offer librarians another means of providing consumers with quality health information.

Implications

  • PHR user support is a new role for medical librarians.
  • Medical librarians need to be proactive in their communities to educate consumers about PHRs.
  • Given the dynamic nature of this market, medical librarians should make a concerted effort to stay abreast of trends in this area.

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.

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.

Objectives:

Standards for evaluating evidence-based medicine (EBM) point-of-care (POC) summaries of research are lacking. The authors developed a “Critical Appraisal for Summaries of Evidence” (CASE) worksheet to help assess the evidence in these tools. The authors then evaluated the reliability of the worksheet.

Methods:

The CASE worksheet was developed with 10 questions covering specificity, authorship, reviewers, methods, grading, clarity, citations, currency, bias, and relevancy. Two reviewers independently assessed a random selection of 384 EBM POC summaries using the worksheet. The responses of the raters were then compared using a kappa score.

Results:

The kappa statistic demonstrated an overall moderate agreement (κ = 0.44) between the reviewers using the CASE worksheet for the 384 summaries. The 3 categories of evaluation questions in which the reviewers disagreed most often were citations (κ =  0), bias (κ = 0.11), and currency (κ = −0.18).

Conclusions:

The CASE worksheet provided an effective checklist for critically analyzing a treatment summary. While the reviewers agreed on worksheet responses for most questions, variation occurred in how the raters navigated the tool and interpreted some of the questions. Further validation of the form by other groups of users should be investigated.

Highlights

  • Few critical appraisal tools have been evaluated with inter-rater reliability testing.
  • The ways that users of evidence-based medicine (EBM) point-of-care (POC) tools interpret how to appraise an evidence summary—particularly when defining the grading of evidence, currency, and bias—may vary even when a standard evaluation sheet is used.
  • The Critical Appraisal for Summaries of Evidence (CASE) worksheet had a moderate level of inter-rater reliability, similar to previous evaluative studies of critical appraisals tools.

Implications

  • Medical librarians can develop tools useful for librarians, students, and clinicians to guide them in appraising clinical evidence summaries.
  • The CASE worksheet can be a valuable tool to consider the quality of individual evidence summaries and to see patterns of overall quality in EBM POC tools.

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.

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.

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.

Objective:

This research measures the effectiveness of the practice of correction and republication of invalidated articles in the biomedical literature by analyzing the rate of citation of the flawed and corrected versions of scholarly articles over time. If the practice of correction and republication is effective, then the incidence of citation of flawed versions should diminish over time and increased incidence of citation of the republication should be observed.

Methods:

This is a bibliometric study using citation analysis and statistical analysis of pairs of flawed and corrected articles in MEDLINE and Web of Science.

Results:

The difference between citation levels of flawed originals and corrected republications does not approach statistical significance until eight to twelve years post-republication. Results showed substantial variability among bibliographic sources in their provision of authoritative bibliographic information.

Conclusions:

Correction and republication is a marginally effective biblioremediative practice. The data suggest that inappropriate citation behavior may be partly attributable to author ignorance.

Highlights

  • The citation of flawed articles occurs at a rate nearly equal to that of corrected versions.
  • The practice of correction and republication is only marginally effective and does not prevent the continued citation of flawed articles post-correction, with the analysis finding only a slight reduction in the citation of flawed articles after publication of the corrected version.
  • Neither MEDLINE nor Web of Science consistently alert users when dealing with corrected and republished literature.

Implications

  • The practice of correction and republication would be more effective if prominent sources of bibliographic information were more consistent in providing users with information about the status of corrected and republished articles and the existence of post-publication modifications to the literature.
  • It is incumbent upon the scientific community to raise the profile of post-publication changes to the literature to prevent the wasteful and potentially tragic consequences of scientists and medical professionals applying flawed information. Failure to do so will surely result in a reduction of public trust in the reliability of the scientific literature and its users.
