Enhancing authenticity, diagnosticity and quivalence (AD-Equiv) in multicentre OSCE exams in health professionals education: protocol for a complex intervention study.

Introduction: Objective structured clinical exams (OSCEs) are a cornerstone of assessing the competence of trainee healthcare professionals, but have been criticised for (1) lacking authenticity, (2) variability in examiners' judgements which can challenge assessment equivalence and (3) for limited diagnosticity of trainees' focal strengths and weaknesses. In response, this study aims to investigate whether (1) sharing integrated-task OSCE stations across institutions can increase perceived authenticity, while (2) enhancing assessment equivalence by enabling comparison of the standard of examiners' judgements between institutions using a novel methodology (video-based score comparison and adjustment (VESCA)) and (3) exploring the potential to develop more diagnostic signals from data on students' performances.

Methods And Analysis: The study will use a complex intervention design, developing, implementing and sharing an integrated-task (research) OSCE across four UK medical schools.

Critical appraisal of interventional clinical trials assessing heated tobacco products: a systematic review.

Objective: To critically assess the methodological characteristics and quality of interventional clinical trials investigating the effects of heated tobacco products (HTPs).

Data Sources: Web of Science (Core collection and MEDLINE), Scopus, MedRxiv, ClinicalTrials.gov and ICTRP trial databases and transnational HTP manufacturer online publication libraries were searched for clinical trials on HTPs published between January 2010 and April 2022.
