Brief summary: The COVID-19 pandemic has disrupted traditional clinical teaching, depriving medical students of valuable clinical engagement with patients who required an aerosol-generating procedure (AGP) in the emergency department (ED). Because of the infection control restrictions, medical students are not allowed to enter resuscitation room where AGPs takes place, even in the aftermath of the pandemic.

The Microsoft HoloLens 2 is an augmented reality (AR) head-mounted device (HMD) which enables a single clinical teacher to facilitate real-time distant immersive learning by medical students on critically ill ED patients while insulating them from infection risks. Our team has successfully developed an AR HMD prototype based on HoloLens for clinical teaching and conducted 10 pilot teaching sessions. Overall, the audio-visual quality of the video-laryngoscope image captured by the HoloLens were rated satisfactorily by the students. Cybersickness symptoms such as dizziness, nausea, and eye strain were infrequent among the viewers.

The investigators conduct a pilot randomised controlled trial (RCT) which aims to evaluate the feasibility of conducting a full-scale RCT. The investigators collect data of the impact of AR learning and bedside learning on student knowledge gain, cognitive load, motivation and adverse effects. The investigators invite 33 Year 5 or 6 medical students to participate in this study during the Emergency Medicine Specialty Clerkship rotation at the Accident and Emergency Department (A\&E) of Queen Mary Hospital (QMH). Consented medical students are randomly assigned in clusters based on their existing student group assignment (around 10 students per each small group) in a 1:1 to two arms: AR clinical learning arm and the control arm (bedside clinical learning).

Randomisation is performed by a research assistant not directly involved in the study using sequentially numbered opaque, sealed envelopes. Given the first-person perspective through the HoloLens, it is not possible to blind the medical students.

To standardise the teaching content of all study sessions, all such sessions are delivered by the principal investigator (PI) of this study during the study period and the pre-reading materials are the same for both groups. The PI will demonstrate endotracheal intubation using video laryngoscope and other AGPs on a manikin in the resuscitation room.
