RESUMO
OBJECTIVE: Hypothetically, content in MEDLINE records is consistent across multiple platforms. Though platforms have different interfaces and requirements for query syntax, results should be similar when the syntax is controlled for across the platforms. The authors investigated how search result counts varied when searching records among five MEDLINE platforms. METHODS: We created 29 sets of search queries targeting various metadata fields and operators. Within search sets, we adapted 5 distinct, compatible queries to search 5 MEDLINE platforms (PubMed, ProQuest, EBSCOhost, Web of Science, and Ovid), totaling 145 final queries. The 5 queries were designed to be logically and semantically equivalent and were modified only to match platform syntax requirements. We analyzed the result counts and compared PubMed's MEDLINE result counts to result counts from the other platforms. We identified outliers by measuring the result count deviations using modified z-scores centered around PubMed's MEDLINE results. RESULTS: Web of Science and ProQuest searches were the most likely to deviate from the equivalent PubMed searches. EBSCOhost and Ovid were less likely to deviate from PubMed searches. Ovid's results were the most consistent with PubMed's but appeared to apply an indexing algorithm that resulted in lower retrieval sets among equivalent searches in PubMed. Web of Science exhibited problems with exploding or not exploding Medical Subject Headings (MeSH) terms. CONCLUSION: Platform enhancements among interfaces affect record retrieval and challenge the expectation that MEDLINE platforms should, by default, be treated as MEDLINE. Substantial inconsistencies in search result counts, as demonstrated here, should raise concerns about the impact of platform-specific influences on search results.

OBJECTIVE: This study investigated responsibilities, skill sets, degrees, and certifications required of health care navigators in order to identify areas of potential overlap with health sciences librarianship. METHOD: The authors conducted a content analysis of health care navigator position announcements and developed and assigned forty-eight category terms to represent the sample's responsibilities and skill sets. RESULTS: Coordination of patient care and a bachelor's degree were the most common responsibility and degree requirements, respectively. Results also suggest that managing and providing health information resources is an area of overlap between health care navigators and health sciences librarians, and that librarians are well suited to serve on navigation teams. CONCLUSION: Such overlap may provide an avenue for collaboration between navigators and health sciences librarians.

This study analyzed the overlap between roles and activities that health care navigators perform and competencies identified by the Medical Library Association's (MLA's) educational policy statement.Roles and activities that health care navigators perform were gleaned from published literature. Once common roles and activities that health care navigators perform were identified, MLA competencies were mapped against those roles and activities to identify areas of overlap. The greatest extent of correspondence occurred in patient empowerment and support. Further research is warranted to determine the extent to which health sciences librarians might assume responsibility for roles and activities that health care navigators perform

OBJECTIVE: The purpose of this study was to investigate the association of selected characteristics of local health departments (LHDs) in Kentucky with the receipt of information by external stakeholders, specifically physicians and pharmacists, during the initial H1N1 outbreak of 2009. METHODS: This study utilized a cross-sectional survey to gather characteristic information from local health departments. In addition, cross sectional surveys of physicians and pharmacists were used to determine information receipt. All 54 LHDs in Kentucky were surveyed; however, only those physicians belonging to the Kentucky Family Physician Association or the Kentucky Ambulatory Network were surveyed. Also, pharmacists included in this survey were members of the Kentucky Pharmacist Association. Descriptive data analyses, including chi-square test of independence, were conducted, and generalized estimating equations were used to calculate odds ratios to depict associations related to information exchange in this study. RESULTS: Response rates for the study were as follows: LHDs 65% (35/54), physicians 18.5% (96/518), and pharmacists 21.1% (211/1000). Of the 35 participating LHDs the most common characteristic identified was the presence of a public information officer (PIO) and a pandemic influenza plan, 76% and 64%, respectively. Despite these factors, 72% of external stakeholders did not receive any information regarding H1N1 from the LHD. Generalized estimating equations also indicated that stakeholders in jurisdictions lacking a PIO had 6 (95% confidence interval, 1.3-26.95) greater odds of not receiving information from the LHD. External stakeholders in jurisdictions without a pandemic influenza plan had 3.38 (95% confidence interval, 0.80-1.17) increased odds of not receiving information but this association was not statistically significant. CONCLUSION: Observations from this study indicate a need to improve information exchange between LHDs and their external stakeholders, specifically physicians and pharmacists. Present results suggest the designation of a PIO may positively influence communication between LHDs and other health care providers, particularly physicians.

This study compared the results of data collected from a longitudinal query analysis of the MEDLINE database hosted on multiple platforms that include PubMed, EBSCOHost, Ovid, ProQuest, and Web of Science. The goal was to identify variations among the search results on the platforms after controlling for search query syntax. We devised twenty-nine cases of search queries comprised of five semantically equivalent queries per case to search against the five MEDLINE database platforms. We ran our queries monthly for a year and collected search result count data to observe changes. We found that search results varied considerably depending on MEDLINE platform. Reasons for variations were due to trends in scholarly publication such as publishing individual papers online first versus complete issues. Some other reasons were metadata differences in bibliographic records; differences in the levels of specificity of search fields provided by the platforms and large fluctuations in monthly search results based on the same query. Database integrity and currency issues were observed as each platform updated its MEDLINE data throughout the year. Specific biomedical bibliographic databases are used to inform clinical decision-making, create systematic reviews, and construct knowledge bases for clinical decision support systems. They serve as essential information retrieval and discovery tools to help identify and collect research data and are used in a broad range of fields and as the basis of multiple research designs. This study should help clinicians, researchers, librarians, informationists, and others understand how these platforms differ and inform future work in their standardization.

There is knowledge in the pages of Appalachia's hills. This journal is positioned to find and publish those translations. It grows from a need to provide an outlet for scholarship about Appalachia's health so that knowledge, and occasionally wisdom, is shared with those who care about and are committed to improving the region's health.
RESUMO
CONTEXT: Public Health Services and Systems Research (PHSSR) is concerned with evaluating the organization, financing, and delivery of public health services and their impact on public health. The strength of the current PHSSR evidence is somewhat dependent on the methods used to examine the field. Methods used in PHSSR articles, reports, and other documents were reviewed to assess their methodologic strengths and challenges in light of PHSSR goals. EVIDENCE ACQUISITION: A total of 364 documents from the PHSSR library met the inclusion criteria as empirical and based in the U.S. After additional exclusions, 327 of these were analyzed. EVIDENCE SYNTHESIS: A detailed codebook was used to classify articles in terms of (1) study design; (2) sampling; (3) instrumentation; (4) data collection; (5) data analysis; and (6) study validity. Inter-coder reliability was assessed for the codebook; once it was found reliable, the available empirical documents were coded. CONCLUSIONS: Although there has been a dramatic increase in the amount of published PHSSR recently, methods used remain primarily cross-sectional and descriptive. Moreover, although appropriate for exploratory and foundational work in a new field, these approaches are limiting progress toward some PHSSR goals. Recommendations are given to advance and strengthen the methods used in PHSSR to better meet the goals and challenges facing the field.

CONTEXT: Public health services and systems research (PHSSR) is the field of study charged with evaluating the public health system. PHSSR currently lacks a clear identity integrating the many theories, approaches, and disciplines contributing to the field. EVIDENCE ACQUISITION: Experts in PHSSR were consulted to identify 11 key published PHSSR studies. With these articles as a starting point, a newly developed citation data collection system was used to collect a sample of 2986 documents connected to the key articles through citation linkages. Data were collected in October 2009. EVIDENCE SYNTHESIS: Citation network methods and latent position cluster modeling were used to examine the network of documents. A subset of 108 documents comprising the backbone of the network was identified through main-path analysis. Four unique clusters were identified within the main path. The core cluster consisted of older articles focused on local health department activities, partnerships, and effectiveness. The three non-core clusters focused on public health law, behavioral interventions, and national performance standards. Although all non-core clusters cited the core, there was little crosstalk among the non-core clusters, a pattern consistent with multidisciplinary fields. CONCLUSIONS: PHSSR appears to be a multidisciplinary field with research happening in silos across different research areas. Developing transdisciplinary research connections across PHSSR is necessary to meet national PHSSR goals.
