Use of epidemiology in clinical medical publications, 1983-1999: a citation analysis

Epidemiologists respond to the information needs of health professionals. Although medical professionals are routine users of epidemiologic information, use within medical specialties varies remarkably. To explore the variation in use of epidemiologic information across clinical medical specialties, the authors examined the scientific literature by analyzing patterns of citation of specific journal articles to and by the American Journal of Epidemiology (AJE). A total of 178,396 journal citations to and 126,478 citations by AJE were made from 1983 through 1999; citations were classified according to the subject category of the referencing or referenced journal. Clinical medical journals accounted for 50.6% of all citations combined (both referenced to and referenced by AJE); general/internal medicine (17.9%), cancer (10.4%), and cardiovascular (4.9%) journals had the highest number of citations. Few citations to and by AJE were found in publications specializing in dermatology, gastroenterology, orthopedics, allergy, anesthesiology, surgery, rheumatology, and other areas. Trend patterns of citations between clinical and epidemiologic literature indicated that citations to the fields of cardiovascular disease and cancer are increasing, whereas citations regarding pediatrics have remained stable. This analysis suggests an increasing interchange of information between epidemiologists and clinicians specializing in certain fields, uncovering potential research opportunities for epidemiologists.

Development of the Cochrane Collaboration's CENTRAL Register of controlled clinical trials

The Cochrane Collaboration has established a centralized database of controlled trials and other studies of health care interventions (called CENTRAL) that serves as the best available resource for all those preparing and maintaining systematic reviews or otherwise searching for trials. CENTRAL is available on The Cochrane Library. This article describes the history and methods of CENTRAL's development and the results of an analysis of the current composition of CENTRAL. As of September 2000, CENTRAL contained almost 300,000 citations to reports of trials, contributed mainly by Cochrane Groups and Centers around the world. Development of CENTRAL has been an ambitious, scholarly undertaking and has resulted in a valuable resource: CENTRAL includes citations to controlled trials that may not be indexed in MEDLINE, EMBASE, or other bibliographic databases; citations published internationally in many languages; and citations that are available only in conference proceedings or other hard-to-access sources.     

Role of the International Radiation Protection Association

Global concerns over energy supply and climate change have given rise to an increase in uranium prospecting, mining and extraction. The changing world economy is spreading the use of advanced nuclear and radiation-related technologies to many parts of the world, giving rise to global initiatives on nuclear energy and operation of nuclear fuel cycle facilities. The emerging global nuclear safety regime promotes and encourages high standards of radiation safety worldwide. These developments call for increasing capacity and capabilities in radiation protection expertise and continue to present both challenges and opportunities to the International Radiation Protection Association (IRPA), an association of 46 societies representing 58 countries with an individual membership of approximately 17,000. IRPA's objectives include: (1) assisting the development of competent radiation protection programs; (2) fostering the exchange of scientific and technical information through its international and regional congresses; (3) promoting the scientific and professional recognition of the radiation protection expert; and (4) supporting continuing education programs at each IRPA congress. IRPA has adopted a Code of Ethics and Guiding Principles for the Conduct of Stakeholder Engagement. Recently work began to develop guidance for maintaining and improving current levels of radiation protection and transferring this culture to future radiation protection professionals. These IRPA projects are developed through the Associate Society Forum discussions that are held at each IRPA international and regional congress. Finally, IRPA maintains a close working relationship with various international organizations and is also represented on the Inter-Agency Committee on Radiation Safety.     

Vaccine hesitancy educational tools for healthcare providers and trainees: A scoping review

In the era of vaccine hesitancy, highlighted by the current SARS-CoV2 pandemic, there is an acute need to develop an approach to reduce and address apprehension towards vaccinations. We sought to map and present an overview of existing educational interventions for healthcare providers (HCPs) on strategies to engage in effective vaccine discussion. We applied the Joanna Briggs Institute methodology framework in this scoping review. We searched five relevant databases (MEDLINE, CINAHL, EMBASE, PsycInfo, and SCOPUS) and grey literature through the Google search engine using keywords and subject headings that were systematically identified. We identified 3384 citations in peer-reviewed literature and 41 citations in grey literature. After screening for our inclusion criteria, we included 28 citations from peer reviewed literature and 16 citations from grey literature for analysis. We identified a total of 41 unique education interventions. Interventions were available from multiple disciplines, training levels, clinical settings, and diseases/vaccines. Interventions predominantly centered around two foci: knowledge sharing and communication training. Most interventions identified from peer-reviewed literature were facilitated and were applied with multiple modes of delivery. Interventions from grey literature were more topical and generally self-directed. We identified several gaps in knowledge. Firstly, accessibility and generalizability of interventions was limited. Secondly, distribution of interventions did not adequately address nursing and pharmacy disciplines, and did not cover the breadth of medical specialties for whom vaccine discussions apply. Thirdly, no interventions addressed self monitoring and the clinicians’ recognition and management of emotions during difficult conversations. There is a need to address this gap and provide available, credible and comprehensive educational interventions that will support our healthcare providers in effective communication with vaccine hesitant patients.

An analysis of American Journal of Epidemiology citations with special reference to statistics and social science

In an effort to inform the ongoing discussion about the purpose, purview, theoretical orientation, and viability of epidemiology, this paper considers the contemporary epistemological foundations of the discipline by analyzing article citations. Two principal questions are the following: 1) What research do American Journal of Epidemiology (AJE) authors rely on to support, inform, and frame their investigations? and 2) to what extent do such authors use social scientific and statistical citations? The data used appear to be superior to those used in previous efforts because they contain complete citations for all articles published, along with complete within-article citations, for all AJE articles published from January 1981 to December 2002. The most frequent AJE citations are statistically oriented works. About 9% of citations are to AJE articles, 15% are to a larger set of eight epidemiologic journals, 15% are to a select set of eight medical journals, 3% are to (bio)statistics journals, and just 0.2% are to social science journals. Trend analysis reveals little change during the 22-year study period. The principal implication is that AJE authors are overlooking a vast literature that could inform their understanding of how exposures emerge and are maintained.

Colciencias and disdain for Colombian scientists: from the Stone Age to the impact factor

Writing has dramatically evolved in the world; however, qualification of scientific production in Colombia has not, including the improper use of decree 1444/93 and 1279/02. The last of these decrees authorized Colciencias, the Colombian government institute created to support scientific research in Colombia, to establish rules for its implementation. Colciencias decided to evaluate scientific papers produced in Colombia based on the non-scientific method of the "impact factor", and considered that citations in MEDLINE/PubMed and PsylNFO were second line publications thus violating Colombian law. This affects not only the progress of scientific research in Colombia but also researchers' income and puts Colombia's scientific journals and publications at great disadvantage. Scientific papers indexed in qualified databases such as MEDLINE/PubMed must be judged according to law in order to prevent further injuries to the developing Colombian scientific production.     

Media coverage of women's health issues: is there a bias in the reporting of an association between hormone replacement therapy and breast cancer?

Media coverage of scientific research plays a major role in shaping public opinion and influencing medical practice. When an association is controversial, such as with hormone replacement therapy (HRT) and breast cancer, it is important that a balanced picture of the scientific literature be reported. The objective of this study was to assess whether scientific publications that do and do not support an HRT/breast cancer association were cited in the media in proportions similar to those with which they appear in the scientific literature. Scientific publications reporting on the HRT/breast cancer association published from January 1, 1995, to June 30, 2000, were identified through a systematic Medline search. Media reports from newspapers, magazines, television, and radio that reported on HRT and breast cancer were retrieved from an online database. Investigators independently recorded characteristics of the scientific publications and media reports. A total of 32 scientific publications were identified: 20 (62.5%) concluded there was an increased risk of breast cancer associated with HRT (positive publications), and 12 (37.5%) concluded there was no evidence for an association (null publications). Nearly half (47%) of the scientific publications were not cited by the media. There were 203 media citations of scientific publications: 82% were of positive publications and 18% were of null publications, representing a significant excess of citations of positive publications (p < 0.01). Media coverage of this controversial issue is based on a limited sample of the scientific publications. Moreover, the excess of media citations for positive scientific publications suggests a bias against null scientific publications.     

Citation analysis and impact factor trends of 5 core journals in occupational medicine, 1985-2006

Longitudinal analysis of citation data provides useful historical information on research and publishing trends in our field. A citation-based analysis was performed on 5 core journals published between 1985 and 2006. Detailed historical information on citation rates, cited half-lives, immediacy indices, and impact-factor scores were extracted from the Thomson Scientific Journal Citation Reports via a custom order, and systematically analyzed. Occupational medicine journals have attracted an increasing number of citations in recent years, with this figure rising from just over 5,000 per year in 1985 to almost 17,000 per year by 2006. Impact factors have also increased between 108% and 186% per journal, with an average rise of approximately 158% during the time period examined. Overall, this study suggests that occupational medicine is now attracting increasing attention in the scientific literature, as evidenced by rising citation counts and impact factors.

Controversies at international organizations over asbestos industry influence.

International scientific organizations have been subject to repeated efforts by Canadian government officials and representatives of the asbestos industry to issue reports that would be favorable to the industry on questions of asbestos use and public health implications. In recent years these efforts have been met with international opposition from scientists, governments, unions, and environmental groups, and a pattern of improprieties, often involving the same individuals and tactics, has emerged. This has been a serious threat to scientific objectivity at the most respected international scientific bodies in the world. The manipulation of these international organizations takes on unprecedented significance in this age of the World Trade Organization.
