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.

Objective:
A discourse analysis was conducted of peer-written blogs about the chronic illness endometriosis to understand how bloggers present information sources and make cases for and against the authority of those sources.Methods:
Eleven blogs that were authored by endometriosis patients and focused exclusively or primarily on the authors'' experiences with endometriosis were selected. After selecting segments in which the bloggers invoked forms of knowledge and sources of evidence, the text was discursively analyzed to reveal how bloggers establish and dispute the authority of the sources they invoke.Results:
When discussing and refuting authority, the bloggers invoked many sources of evidence, including experiential, peer-provided, biomedical, and intuitive ones. Additionally, they made and disputed claims of cognitive authority via two interpretive repertoires: a concern about the role and interests of the pharmaceutical industry and an understanding of endometriosis as extremely idiosyncratic. Affective authority of information sources was also identified, which presented as social context, situational similarity, or aesthetic or spiritual factors.Conclusions:
Endometriosis patients may find informational value in blogs, especially for affective support and epistemic experience. Traditional notions of authority might need to be revised for the online environment. Guidelines for evaluating the authority of consumer health information, informed by established readers'' advisory practices, are suggested.Highlights
- Endometriosis patients who blog about the illness may determine authority of information sources through both cognitive and affective methods.
Implications
- Because patients with chronic illnesses might have different authority criteria than medical librarians do, it could be useful to carefully incorporate electronic patient discussion forums, medical blogs written by laypeople, and other nontraditionally authoritative resources into consumer health information selection policies. Standard biomedical resources are certainly important to recommend to consumers, but they do not convey the complete picture of a chronic illness and its related experience.
- Patients with chronic illnesses and caregivers can benefit from sources such as blogs and online discussion lists that provide social and emotional support as well as accounts of “lived experience.”
- An understanding of the patient''s potential epistemological community can make the librarian''s recommendations more appropriate for the individual user.

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.

Objectives:
The purposes of this study were: to determine the number of articles requested by library users that could be retrieved from the library''s collection using the library catalog and link resolver, in other words, the availability rate; and to identify the nature and frequency of problems encountered in this process, so that the problems could be addressed and access to full-text articles could be improved.Methods:
A sample of 414 requested articles was identified via link resolver log files. Library staff attempted to retrieve these articles using the library catalog and link resolver and documented access problems.Results:
Staff were able to retrieve electronic full text for 310 articles using the catalog. An additional 21 articles were available in print, for an overall availability rate of nearly 80%. Only 68% (280) of articles could be retrieved electronically via the link resolver. The biggest barriers to access in both instances were lack of holdings and incomplete coverage. The most common problem encountered when retrieving articles via the link resolver was incomplete or inaccurate metadata.Conclusion:
An availability study is a useful tool for measuring the quality of electronic access provided by a library and identifying and quantifying barriers to access.Highlights
- Lack of holdings, including access to recent articles restricted by embargoes, was the most common barrier to locating full text, accounting for over 90% of all identified problems.
- Availability rates for electronic articles varied by year of publication and by the database in which the OpenURL request originated.
- Link resolver error rates varied widely based on the source of the request and frequently resulted from incomplete or inaccurate metadata.
Implications
- An availability study is an inexpensive, practical tool for assessing the quality of electronic access to journal articles.
- The results of an availability study can help libraries identify barriers to access and thereby allocate limited resources to areas that will provide the most benefit to users.
- Link resolvers might be more accurate if the quality of metadata in OpenURLs was improved and the behavior of full-text targets was standardized.
- Collection and acquisition problems: The library may not subscribe to the desired journal, or the article and/or journal may be unavailable for some other reason.
- Cataloging and holdings problems: The journal may be cataloged or indexed incorrectly, or the library''s holdings data may be wrong.
- Technical problems: Problems may occur with the journal provider''s site or the library''s proxy server.
- gather actual user requests (or simulate them)
- try to fill those requests using the same tools and methods a user would use
- record what happens
- analyze the results

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:
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.

Objectives:
The purpose of this study was to identify (1) core journals in the literature of physical therapy, (2) currency of references cited in that literature, and (3) online databases providing the highest coverage rate of core journals.Method:
Data for each cited reference in each article of four source journals for three years were recorded, including type of literature, year of publication, and journal title. The journal titles were ranked in descending order according to the frequency of citations and divided into three zones using Bradford''s Law of Scattering. Four databases were analyzed for coverage rates of articles published in the Zone 1 and Zone 2 journals in 2007.Results:
Journal articles were the most frequently cited type of literature, with sixteen journals supplying one-third of the cited journal references. Physical Therapy was the most commonly cited title. There were more cited articles published from 2000 to 2007 than in any previous full decade. Of the databases analyzed, CINAHL provided the highest coverage rate for Zone 1 2007 publications.Conclusions:
Results were similar to a previous study, except for changes in the order of Zone 1 journals. Results can help physical therapists and librarians determine important journals in this discipline.Highlights
- More cited references were published in the last eight years studied than in any previous full decade.
- Physical Therapy, Archives of Physical Medicine and Rehabilitation (APMR), and Spine were the most frequently cited titles. Previous studies found APMR to be the most cited journal.
- CINAHL provided the highest coverage rate for the most commonly cited titles, with MEDLINE and EMBASE providing the best coverage for the next group of titles.
Implications
- Health sciences librarians and clinicians can use these results to identify important journals for developing collections and determining the need for access to back issues of journals.
- Multiple databases are needed for comprehensive coverage of the physical therapy discipline

Objectives:
The 170-year history of the library of the Royal Society of Medicine in Budapest illustrates both that political and cultural context matter and that “medical” libraries, if they survive, in due course become primarily “medical history” libraries.Methods:
Two of the authors are on the staff of the Semmelweis Medical History Library; the third is a US scholar who makes frequent use of the library. Together, they avail themselves of archival and published materials—and personal experience with the collection—to establish the context that produced the original library, trace its evolution, and describe its present-day incarnation.Results:
A tale of transformation emerges that reflects how collections are likely to change. The authors present events and individuals in the life of the Royal Society''s library and paint a picture of the value of today''s Semmelweis Medical History Library. Unique treasures in the collection are described.Conclusion:
The story told here is of how a particular nineteenth-century library became a twenty-first–century institution. The authors establish its peculiarly Hungarian context and potential value to librarians and historians from outside Hungary. The overall message is that general medical libraries everywhere are perforce likely to become medical historical libraries over time.Highlights
- Context matters. The historical background of a library helps determine its functions and its future; shifts in modes of publishing affect and monetary concerns shape the development and preservation of an historical collection.
- Libraries evolve. Medical libraries undergo a normal and profoundly useful transformation over time into repositories of medical history.
- Books alone do not a library make: Libraries can and should be settings for continuing education, cultural affirmation, and assistance to scholars by preserving and making available for use a variety of sometimes rare archival and published materials.
Implications
- Knowing the political and cultural background of a library is essential to understanding its history as well as its present-day status.
- Preserving and expanding historical collections demands vigilance and creative management, especially under difficult fiscal and political circumstances. The loyal and diligent work of Hungarians and others who helped build and preserve this library can serve as a model for other threatened collections.
- Sharing the story of a relatively unknown library''s development brings its general assets and unique resources to the attention of a wider audience of librarians and scholars. Few outside Hungary have previously had any way of knowing about the Semmelweis Medical History Library''s rich holdings.

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.

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:
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.

Objectives:
This research studied hospital administrators'' and hospital-based health care providers'' (collectively, the target group) perceived value of consumer health information resources and of librarians'' roles in promoting health information literacy in their institutions.Methods:
A web-based needs survey was developed and administered to hospital administrators and health care providers. Multiple health information literacy curricula were developed. One was pilot-tested by nine hospital libraries in the United States and Canada. Quantitative and qualitative methods were used to evaluate the curriculum and its impact on the target group.Results:
A majority of survey respondents believed that providing consumer health information resources was critically important to fulfilling their institutions'' missions and that their hospitals could improve health information literacy by increasing awareness of its impact on patient care and by training staff to become more knowledgeable about health literacy barriers. The study showed that a librarian-taught health information literacy curriculum did raise awareness about the issue among the target group and increased both the use of National Library of Medicine consumer health resources and referrals to librarians for health information literacy support.Conclusions:
It is hoped that many hospital administrators and health care providers will take the health information literacy curricula and recognize that librarians can educate about the topic and that providers will use related consumer health services and resources.Highlights
- Health care providers responded positively to a health information literacy curriculum offered by librarians and to related resources and services, namely MedlinePlus and the information referral system known as Information Rx.
- Participation in a curriculum increased health care providers'' knowledge of health information literacy, awareness of available consumer health information, and referral of patients to the library for additional assistance.
- Librarian involvement in health information literacy increased the profession''s visibility and perceived value.
Implications
- Consumer health information services and resources offered by librarians can improve the health information literacy skills of health care providers and their patients.
- Training by librarians can increase knowledge of the importance of health information literacy and usage of MedlinePlus and Information Rxs.
- Hospital-based administrators and health care providers can be champions in support of health information literacy and consumer health information services offered by libraries.

Objective:
A survey was conducted of health sciences libraries to obtain information about newer buildings, additions, remodeling, and renovations.Method:
An online survey was developed, and announcements of survey availability posted to three major email discussion lists: Medical Library Association (MLA), Association of Academic Health Sciences Libraries (AAHSL), and MEDLIB-L. Previous discussions of library building projects on email discussion lists, a literature review, personal communications, and the author''s consulting experiences identified additional projects.Results:
Seventy-eight health sciences library building projects at seventy-three institutions are reported. Twenty-two are newer facilities built within the last ten years; two are space expansions; forty-five are renovation projects; and nine are combinations of new and renovated space. Six institutions report multiple or ongoing renovation projects during the last ten years.Conclusions:
The survey results confirm a continuing migration from print-based to digitally based collections and reveal trends in library space design. Some health sciences libraries report loss of space as they move toward creating space for “community” building. Libraries are becoming more proactive in using or retooling space for concentration, collaboration, contemplation, communication, and socialization. All are moving toward a clearer operational vision of the library as the institution''s information nexus and not merely as a physical location with print collections.Highlights
- Seventy-eight health sciences library building projects at seventy-three institutions were reported as completed in the last ten years.
- Five health sciences library projects illustrate the diversity of projects reported.
- Eleven trends in health sciences library buildings are identified.
- Numerous challenges are briefly discussed.
Implications
- Changing services and usage patterns demand innovative ways to use library space.
- Libraries are making more proactive efforts to retool library physical space.
- Migration from print to digital collections is continuing at an accelerated pace.
- More library space is now dedicated for “community” building.
