Translation and cross-cultural adaptation of Persian version of Evidence Based Medicine Questionnaire (EBMQ) in postgraduate medical students in Iran.

BACKGROUND: Evidence Based Medicine Questionnaire (EBMQ) was developed to assess the knowledge, practice and barriers towards the implementation of Evidence-Based Medicine (EBM). This study aimed to translate, cross-culturally adapt and psychometrically validate the Persian version of EBMQ. METHODS: This was an analytical cross sectional study. The EBMQ underwent translation and cross-cultural adaptation following best practices. Face validity was assessed by a panel of five experts. The content validity index (CVI) and content validity ratio (CVR) were evaluated by 15 experts who were familiar with EBM. The tool's internal consistency and test-retest reliability over a 2-week period were evaluated using Cronbach's α and intra-class correlation (ICC), respectively. To assess construct validity, the questionnaire was completed by 400 medical students. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used for construct validity assessment. All analyses were carried out using IBM SPSS v.24 and AMOS v.24. A significance level of 5% was considered. RESULTS: The CVR for 40 items was higher than 0.62, and their CVI score was 1.0, indicating good content validity. The scale demonstrated acceptable internal consistency and test-retest reliability (n = 30) with an ICC of 0.909 (95% CI: 0.866 to 0.941), and an overall alpha coefficient of 0.957. The structural validity was established through exploratory factor analysis (Bartlett's test p<0.001; the Kaiser-Meyer-Olkin index = 0.862), and it was further confirmed by confirmatory factor analysis. A three-factor solution with 40 items, explaining 51.610% of the variance, exhibited the best fit indices Chi-square statistics/df = 4.23; RMSEA = 0.08; CFI = 0.95; NFI = 0.93; TLI = 0.92). CONCLUSION: The Persian version of the EBMQ was a reliable and valid tool that could be utilized to assess the knowledge, practice and barriers of EBM for physicians in Persian language countries.

Mapping Global Research in Emergency Medicine; a Bibliometric Analysis of Documents Indexed in the Web of Science Database.

Introduction: Emergency medicine is a relatively new and rapidly growing specialty, and its research monitoring is important for future policies. This study aimed to analyze the published literature related to emergency medicine, to create a documented research perspective for this field. Methods: This research is a bibliometric study that analyzes the research outputs of the subject area of emergency medicine indexed in the Web of Science database from the beginning to 2023. VOSviewer software was used to visualize and predict the trends in research on the topic. Results: The findings showed that the University of California, The Journal of Neurotrauma and Brain Injury, Elsevier, and the USA were the most prolific units in the cycle of scientific productions in the field of emergency medicine. Results showed that most scientific productions in this field fall into 6 clusters: psychological impressions, injuries caused by traumatic events and the effects of traumas on children, pathophysiology and nervous system issues and related diseases, complications of traumatic events and injuries, biomechanics and complications caused by sports injuries, and consciousness. Conclusion: In addition to interventions and clinical complications, research in the field of emergency medicine has also focused on psychological structures. So, based on various measurement indicators, the subjects of this field have been the focus of researchers' attention.

Challenges of the Presence and Absence of Clinical Librarians in the Use of Evidence-Based Medicine in Clinical Departments.

Due to the rapid growth of information technology and medical information resources, medical personnel need to search and retrieve valid and updated information. However, with limited time to access these resources, there is a need for clinical librarians to connect medical staff to evidence-based medicine (EBM). The present study was conducted to identify the challenges in the absence and the benefits of the presence of clinical librarians in the application of EBM in clinical departments. Ten clinical physicians working at Children's Medical Center Hospital in Tehran, Iran were interviewed for this qualitative study. Most of the hospital-based physicians did not make any systematic use of EBM and seven were not familiar with the term "clinical librarian." In their opinion, the clinical librarians' activities included training the clinical and research teams, providing them with the required information, and providing an EBM-oriented approach to morning report and educational rounds. Therefore, the services delivered by clinical librarians in various hospital departments might positively influence the hospital-based physicians' information-seeking behavior.

Scientometric Study of Research in Information Retrieval in Medical Sciences.

Background: Mapping scientific trends is one of the most important missions of scientometric research for effective research. The main goal of this paper was to visualize and draw the intellectual and cognitive structures of information retrieval (IR) in the medical sciences using science mapping. Methods: In this cross-sectional scientometric study, we recruited all documents indexed in the Web of Science database with the topic of storing and retrieval of information in medical sciences. To analyze the results, 3 software, SciMAT-v1.1.04, VOSviewer-v1.6.14, CitNetExplorer_v1.0.0, were used. Results: Our results showed that most scientific productions in this field fall into 2 categories: (1) effective methods of organizing information and (2) application and operation of the IR system in the process of intelligent questioning and answering, and analyzing information behaviors of physicians and health professionals. The results showed that the similarity index increased over time from 0.43 to 0.71. Analysis of the findings showed that similarity measures, expert systems, concepts, experience, answers, and multimodel IR clusters were considered as mature and completely centralized clusters in the first quarter of the strategic chart. Conclusion: Because of the dramatic approximation of the vocabulary used by researchers and a relative slowdown in the growth rate of the subject's domain in the last decade, it seems necessary to pay attention to the expansion of the fields of IR and the application of its concepts in medical information sciences. Also, it can be recommended that designers of IR systems and techniques in medical information sciences pay more attention to human factors attentively to develop new technologies and tools.

Designing a model of professional ethics excellence for clinical librarians.

OBJECTIVE: Developing and promoting professional ethics principles for clinical librarians can help the health care system balance the interests of all stakeholders, including clinical librarians, health care professionals, and patients. Therefore, the goal of this study was to design a model of professional ethics excellence for clinical librarians. METHODS: The authors conducted a descriptive applied study using literature review and the delphi method. The delphi panel included eleven experts in medical librarianship, library and information sciences, or information sciences and knowledge studies. RESULTS: After the delphi rounds, five concepts and forty-six components were identified and confirmed to provide a model of professional ethics excellence for clinical librarians. The highest-rated concept was excellence in communication. The highest-rated component was mastery in developing search strategies in information resources and databases. CONCLUSIONS: Identifying and applying principles of professional ethics among clinical librarians can enhance the professionalization of clinical librarians and result in better information services for physicians. Furthermore, incorporating these principles into the curriculum for health sciences library and information sciences students or into workshops for active clinical librarians can further formalize the profession and practice of evidence-based medicine.
