“…In Mexico, 20% of accredited curriculums offer single EBM courses as required, accounting for 0.08% of the total academic credits. These findings align with the limitations observed at the global level 38. Students also learn during informal interactions with their teachers and through organisational culture; however, academic instructional offerings ensure that the educational objectives of the medical school are met 39.…”

ObjectivesTo assess the teaching of evidence-based medicine (EBM) in medical curriculums. As a secondary objective, we assessed the representativeness of science courses related to EBM.Design and settingSystematic review. Accredited curriculums by the Mexican Council for the Accreditation of Medical Education.Main outcome measuresWe provided a descriptive analysis of the required or elective EBM courses and EBM-related courses, academic credits and teaching period. EBM-related courses included research methodology, epidemiology, biostatistics, clinical research, public health, clinical epidemiology, scientific dissemination and health informatics to explore scientific education and training offered by medical schools. Additionally, we examined the curriculum’s structure, location, type of institution, total programme duration and academic credits. Data collection occurred from December 2020 to February 2021.ResultsWe identified 171 registered curriculums, of which we assessed 60 unique programmes (50% public) in our analysis. We identified 16 EBM single courses on the fifth and sixth semesters, of which 12 (20%) were mandatory and 4 were electives (6.7%). The allocated academic credits for EBM courses are minimal, without difference between public or private institutions, representing 0.08% of the total curriculum. Public health, epidemiology, research methodology and biostatistics courses are offered with greater frequency (55% or less) and curricular value (0.6% or less). In some cases, they are taught as combined courses. Clinical research, health informatics and clinical epidemiology are taught less than EBM, while scientific dissemination is nil.ConclusionIn Mexico, EBM teaching is limited to only one of five curriculums with minimal curricular value. A comprehensive curricular review is necessary across programmes to incorporate EBM as a first step to improve medical education and, consequently, public health. We call to action through an online, collaborative platform with several applications to optimise teaching of EBM.Review protocol registrationThe systematic review protocol is excluded from the International Prospective Register of Systematic Reviews since this platform only accepts systematic reviews with health-related outcomes.

“…It is worth highlighting that the reporting of SRs of RCTs and RCTs in The New York Times and The Times , respectively, may be seen as an indicator of good quality journalism. It should also be noted that the USA and the UK are the countries that produce the most Cochrane SRs [ 50 ] and that newspapers tend to report more on domestically produced science [ 23 ]. On the other hand, the over-representation of animal/laboratory studies in the business newspapers, which is mainly down to The Wall Street Journal , is expected as preclinical microbiome research (representing 30.4% of microbiome studies in PubMed) is the first step towards developing microbiome therapies, and that is where most companies’ initial efforts begin.…”

The microbiome is a matter of interest for science, consumers and business. Our objective is to quantify that interest in academic journals and newspapers, both quantitatively and by study design. We calculated the number of articles on the microbiome from the total number of biomedicine articles featured in both PubMed and Spanish science news agency SINC, from 2008 to 2018. We used the Factiva database to identify news stories on microbiome papers in three general newspapers (The New York Times, The Times and El País) and three business newspapers (The Wall Street Journal, the Financial Times and Expansión), from 2007 to 2019. Then, we compared news stories with microbiome papers in PubMed, while also analyzing the frequencies of five study design types, both in the newspapers and in the papers themselves. Microbiome papers represented 0.8% of biomedicine papers in PubMed from 2008 to 2018 (increasing from 0.4% to 1.4%), while microbiome news published by SINC represented 1.6% of total biomedical news stories during the same period (increasing from 0.2% to 2.2%). The number of news stories on microbiome papers correlated with the number of microbiome papers (0.91, p < 0.001) featured in general newspapers, but not in business ones. News stories on microbiome papers represented 78.9% and 42.7% of all microbiome articles in general and business newspapers, respectively. Both media outlet types tended to over-report observational studies in humans while under-reporting environmental studies, while the representation of systematic reviews of randomized controlled trials, randomized controlled trials and animal/laboratory studies was similar when comparing newspapers and PubMed. The microbiome is receiving increasing attention in academic journals and newspapers. News stories on the microbiome in general and business newspapers are mostly based on research findings and are more interested in observational studies in humans and less in environmental studies compared to PubMed.

“…In addition, countries that belong to the Commonwealth have been separated (cf. Encyclopaedia Britannica, 2021), due to their stronger commitment to evidence-based medicine (Groneberg et al, 2019).…”

“…While marking seventh with 4.8%, its portions grew steadily year over year, taking the second rank in 2015 with over 1000 items and 18% of overall share. Groneberg et al have shown that strong commitments towards evidence-based medicine can be associated with the Commonwealth (Groneberg et al, 2019). Similarly, the analysis of document types shows that such countries, especially the U.K., Canada, Australia or New Zealand, produce higher rates of systematic reviews and its PRISMA-based counterpart than other leading science nations (Figs.…”

The question of how citation impact relates to academic quality accompanies every decade in bibliometric research. Although experts have employed more complex conceptions of research quality for responsible evaluation, detailed analyses of how impact relates to dimensions such as methodological rigor are lacking. But the increasing number of formal guidelines for biomedical research offer not only the potential to understand the social dynamics of standardization, but also their relations to scientific rewards. By using data from Web of Science and PubMed, this study focuses on systematic reviews from biomedicine and compares this genre with those systematic reviews that applied the PRISMA reporting standard. Besides providing an overview about growth and location, it was found that the latter, more standardized type of systematic review accumulates more citations. It is argued that instead of reinforcing the traditional conception that higher impact represents higher quality, highly prolific authors could be more inclined to develop and apply new standards than more average researchers. In addition, research evaluation would benefit from a more nuanced conception of scientific output which respects the intellectual role of various document types.
