CONTEXT The increasing use of Internet-based learning in health professions education may be informed by a timely, comprehensive synthesis of evidence of effectiveness. OBJECTIVES To summarize the effect of Internet-based instruction for health professions learners compared with no intervention and with non-Internet interventions. DATA SOURCES(More)
UNLABELLED Validity and reliability relate to the interpretation of scores from psychometric instruments (eg, symptom scales, questionnaires, education tests, and observer ratings) used in clinical practice, research, education, and administration. Emerging paradigms replace prior distinctions of face, content, and criterion validity with the unitary(More)
CONTEXT Methodological shortcomings in medical education research are often attributed to insufficient funding, yet an association between funding and study quality has not been established. OBJECTIVES To develop and evaluate an instrument for measuring the quality of education research studies and to assess the relationship between funding and study(More)
Beneficial effects with statin use are increasingly reported in a variety of patient groups. There is in vitro and clinical evidence for its antiinflammatory and immunomodulatory therapeutic roles. We aimed to assess the association between statin administration and mortality in bacteraemic patients. A retrospective cohort analysis. A 300-bed acute general(More)
During ischemic stroke, neurons at risk are exposed to pathologically high levels of intracellular calcium (Ca++), initiating a fatal biochemical cascade. To protect these neurons, we have developed openers of large-conductance, Ca++-activated (maxi-K or BK) potassium channels, thereby augmenting an endogenous mechanism for regulating Ca++ entry and(More)
CONTEXT The opposing forces of increased training expectations and reduced training resources have greatly impacted health professions education. Virtual patients (VPs), which take the form of interactive computer-based clinical scenarios, may help to reconcile this paradox. METHODS We summarise research on VPs, highlight the spectrum of potential(More)
CONTEXT Although technology-enhanced simulation has widespread appeal, its effectiveness remains uncertain. A comprehensive synthesis of evidence may inform the use of simulation in health professions education. OBJECTIVE To summarize the outcomes of technology-enhanced simulation training for health professions learners in comparison with no(More)
PURPOSE A recent systematic review (2008) described the effectiveness of Internet-based learning (IBL) in health professions education. A comprehensive synthesis of research investigating how to improve IBL is needed. This systematic review sought to provide such a synthesis. METHOD The authors searched MEDLINE, CINAHL, EMBASE, Web of Science, Scopus,(More)
PURPOSE Mentoring is vital to professional development in the field of medicine, influencing career choice and faculty retention; thus, the authors reviewed mentoring programs for physicians and aimed to identify key components that contribute to these programs' success. METHOD The authors searched the MEDLINE, EMBASE, and Scopus databases for articles(More)
CONTEXT Authors have questioned the degree to which medical education research informs practice and advances the science of medical education. OBJECTIVE This study aims to propose a framework for classifying the purposes of education research and to quantify the frequencies of purposes among medical education experiments. METHODS We looked at articles(More)
