Background With increasing popularity of marijuana, consumers are likely turning to the internet for information regarding medical marijuana. Accuracy of medical marijuana claims is a significant concern because consumers change their medication management based on information from a single website. Objective The purpose of this study was to evaluate the accuracy and quality of medical marijuana claims on popular websites. Methods : Commonly used websites containing claims regarding medical marijuana were selected by utilizing three online marketing tools that rank websites based on number of views, number of visitors, and visitor engagement. Once the top ten most popular websites were selected, medical claims regarding marijuana were reviewed for accuracy and quality using evidence-based tools. Results Seventy-six percent of claims made by websites were inaccurate and were based on low-quality evidence. Of the medical marijuana claims reviewed, 10% of websites made appropriate cause and effect conclusions. Furthermore, approximately 3% of the medical marijuana claims were written by a healthcare professional. Conclusion The findings show there is misleading and inaccurate information readily available to consumers online.

‘Evidence-based approaches to psychiatry’ describes the application of evidence-based medicine (EBM) to psychiatric practice. The chapter covers the key processes in EBM, including the formulation of a clinically relevant question, the systematic search for high-quality evidence and the meta-analytic synthesis of data. It demonstrates how evidence-based approaches to psychiatry have led to important developments showing quantitative effects of different treatments through advanced meta-analysis of data from randomized trials. This has underpinned the development of clinical guidelines that have the aim of improving the reliability and quality of treatments that patients receive. The chapter also describes how meta-analyses should be critically reviewed, as well as their problems and limitations. Not all relevant questions in psychiatric research are susceptible to the quantitative approach offered by EBM, and the chapter also outlines how qualitative methodologies can play a key role in answering important questions related, for example, to the patient experience.

Esta investigación examina la relación entre el tiempo de uso de Internet y el rendimiento académico cuantitativo y cualitativo de 127 estudiantes de nivel universitario, confrontado con la información aportada por 15 docentes del mismo nivel; toda la población estudiada emplea Internet, y emplearlo como herramienta de estudio contribuye positivamente al rendimiento académico, puesto que el estudiante debe seleccionar, analizar y comprender la información encontrada, lo que se corrobora al aplicar el coeficiente de Pearson y obtener un valor de 0.80. Sin embargo, los deberes desarrollados por los estudiantes con información obtenida de Internet presentan una realidad diferente: el 66.67% de los trabajos se califican entre bueno y regular, lo que evidencia la falta de aporte a la calidad de los mismos: en su mayoría los docentes comentan que son copias textuales de los documentos consultados o contienen información errada, haciéndose necesario el aporte adicional con un enfoque innovador a los procesos de consulta, que lleven al análisis crítico y constructivo para que  estas tareas sean procesos productivos de desarrollo de conocimiento.AbstractThis research examines the relationship between Internet usage time and the quantitative and qualitative achievement of 127 students at the university level, confronted with the information provided by 15 teachers at the same level; entire study population uses the Internet. It`s use as a study tool contributes positively to academic performance, since the student must select, analyze and understand the information found, which is corroborated by applying the Pearson Coefficient and get a value of 0.80. However, the duties developed by students with information obtained from the Internet presents a different reality: 66.67% of jobs are rated between good and fair, which shows the lack of contribution to the quality of them: mostly the teachers report that are verbatim copies of documents consulted or contain inaccurate information, making necessary the additional contribution with an innovative consultation processes, leading to critical and constructive analysis for these tasks are productive processes of knowledge development approach.

SummaryThe internet provides access to what is often a bewildering array of medical knowledge on mental health, some (but not all) of which is evidence based. As well as information for clinicians, there has been a dramatic increase in the variety and quality of information available for patients and carers. In this article we discuss the advantages and limitations of the types of information available, with suggested sites and strategies for assessing their relative merits.

The internet has become a popular resource to learn about health and to investigate one's own health condition. However, given the large amount of inaccurate information online, people can easily become misinformed. Individuals have always obtained information from outside the formal health care system, so how has the internet changed people's engagement with health information? This review explores how individuals interact with health misinformation online, whether it be through search, user-generated content, or mobile apps. We discuss whether personal access to information is helping or hindering health outcomes and how the perceived trustworthiness of the institutions communicating health has changed over time. To conclude, we propose several constructive strategies for improving the online information ecosystem. Misinformation concerning health has particularly severe consequences with regard to people's quality of life and even their risk of mortality; therefore, understanding it within today's modern context is an extremely important task.

Bronchiectasis is an increasingly common disease with a significant impact on quality of life and morbidity of affected patients. It is also a very heterogeneous disease with numerous different underlying etiologies and presentations. Most treatments for bronchiectasis are based on low-quality evidence; consequently, no treatments have been approved by the US Food and Drug Administration or the European Medicines Agency for the treatment of bronchiectasis. The last several years have seen numerous clinical trials in which the investigational agent, thought to hold great promise, did not demonstrate a clinically or statistically significant benefit. This commentary will review the likely reasons for these disappointing results and a potential approach that may have a greater likelihood of defining evidence-based treatment for bronchiectasis.

Abstract Objective To investigate whether alignment of strength of recommendations with quality of evidence differs in consensus based versus evidence based guidelines. Design Empirical analysis. Data source Guidelines developed by the American College of Cardiology and the American Heart Association (ACC/AHA) and the American Society of Clinical Oncology (ASCO) up to 27 March 2021. Study selection Recommendations were clearly categorised as consensus or evidence based, were separated from the remainder of the text, and included both the quality of evidence and the strength of the recommendations. Data extraction Paired authors independently extracted the recommendation characteristics, including type of recommendation (consensus or evidence based), grading system used for developing recommendations, strength of the recommendation, and quality of evidence. The study team also calculated the number of discordant recommendations (strong recommendations with low quality evidence) and inappropriate discordant recommendations (those that did not meet grading of recommendations assessment, development, and evaluation criteria of appropriateness). Results The study included 12 ACC/AHA guidelines that generated 1434 recommendations and 69 ASCO guidelines that generated 1094 recommendations. Of the 504 ACC/AHA recommendations based on low quality evidence, 200 (40%) proved to be consensus based versus 304 (60%) evidence based; of the 404 ASCO recommendations based on low quality evidence, 292 (72%) were consensus based versus 112 (28%) that were evidence based. In both ACC/AHA and ASCO guidelines, the consensus approach yielded more discordant recommendations (ACC/AHA: odds ratio 2.1, 95% confidence interval 1.5 to 3.1; ASCO: 2.9, 1.1 to 7.8) and inappropriate discordant recommendations (ACC/AHA: 2.6, 1.7 to 3.7; ASCO: 5.1, 1.6 to 16.0) than the evidence based approach. Conclusion Consensus based guidelines produce more recommendations violating the evidence based medicine principles than evidence based guidelines. Ensuring appropriate alignment of quality of evidence with the strength of recommendations is key to the development of “trustworthy” guidelines.

The evidence movement has attended more to improving the supply of evidence than to increasing demand, so even as rigorous evidence production has increased, the use of evidence remains all too rare. A growing body of research indicates that the quality of relationships between researchers, policy-makers, and intermediaries plays a central role in whether rigorous evidence informs decisions in policy and practice. Creating structures to support such relationships remains a major challenge. Yet even when high-quality evidence is used, the intended benefits may not ensue because of broader challenges in society at large. Consequently, we should temper our expectations for the benefits of evidence-based policymaking, but not give up the effort.

Abstract This special section presents the psychometric properties of fidelity scales used in a national mental health services project in Norway to improve the quality of care of people with psychoses. Across Norway, 39 clinical units in six health trusts participated. The project provided education, implementation support and fidelity assessments. The papers in the section address the psychometrics of fidelity measurement for the specific evidence-based practices: illness management and recovery, family psychoeducation, physical healthcare and antipsychotic medication management. Another paper analyzes the psychometrics of a scale measuring individualization and quality improvement that may be used in conjunction with fidelity scales for specific evidence-based practices. The first paper in the section presents the development and field of fidelity scales, and the two final papers with comments add some additional perspectives and discuss fidelity scales in a wider context. The psychometrics of the five scales were good to excellent. Fidelity assessment is a necessary and effective strategy for quality improvement.

Violence prevention is of the utmost concern in some schools.  For various reasons, rural schools face a number of challenges that may prevent them from implementing strong, evidence-based violence prevention initiatives.  Given that the Internet houses a plethora of cost-free resources on threat assessment and violence prevention in schools, rural educators may consult the internet for information.  However, because little is known about the composition and quality of such resources, it is important that they are properly evaluated.  As such, the purpose of the present study was to compare existing, free, online school-based threat assessment resources to an evidence-based threat assessment framework to determine how well online resources communicate evidence-based principles.  Using component analysis, a total of 11 online resources were evaluated.  Overall, the findings from this investigation revealed that the evaluated online threat assessment resources were not as comprehensive as evidence-based guidelines.              Keywords: online, prevention, schools, threat assessment, violence
