The number needed to teach: A framework for health professions education.

What Is The Educational Challenge?: Health professions education is continually limited by financial resources with increasing demands for accountability. Judicious resource allocation across competing demands rests on frameworks for analyzing and comparing costs and outcomes.

What Are The Proposed Solutions?: We suggest health professions educators use the number needed to teach (NNTe) for reporting and communicating such analyses for teaching and learning.

Pre- and apnoeic high-flow oxygenation for rapid sequence intubation in the emergency department (the Pre-AeRATE trial): A multicentre randomised controlled trial.

Introduction: Evidence regarding the efficacy of high-flow nasal cannula (HFNC) oxygenation for preoxygenation and apnoeic oxygenation is conflicting. Our objective is to evaluate whether HFNC oxygenation for preoxygenation and apnoeic oxygenation maintains higher oxygen saturation (SpO) during rapid sequence intubation (RSI) in ED patients compared to usual care.

Methods: This was a multicentre, open-label, randomised controlled trial in adult ED patients requiring RSI.

Cross-sectional study of perceptions of qualities of a good medical teacher among medical students from first to final year.

Introduction: Defining the characteristics of a good medical teacher has implications for faculty selection and development. Perceptions of characteristics may differ with cultural context and level of training, as medical students progress from didactic preclinical training based on cognitivist learning theory to more complex integration of theory and practice in specific contexts in clinical training based on constructivist learning theory.

Methods: We modified a validated questionnaire with permission from the original authors at Melaka Manipal Medical College, Melaka, Malaysia.

Pre- and Apnoeic high flow oxygenation for RApid sequence intubation in The Emergency department (Pre-AeRATE): study protocol for a multicentre, randomised controlled trial.

Background: Maintaining adequate oxygenation during rapid sequence intubation (RSI) is imperative to prevent peri-intubation adverse events that can lead to increased duration of hospital and intensive care unit stay, or a prolonged vegetative state requiring long-term institutionalisation. Despite employing current best practices during RSI, desaturation during intubation still occurs. High-flow nasal cannula (HFNC) oxygenation may potentially improve oxygenation during pre- and apnoeic oxygenation to allow a longer safe apnoeic time for RSI.
