ARCTICA is a prospective multi-site study that will evaluate a virtual Tele-POCUS educational intervention for non-conventional users of ultrasound assessing patients with dyspnea in geographically remote centres supported by tertiary centres in a cross-Canada Hub and Spoke model.

The ARCTICA project will:  (1) Accelerate virtual teaching of POCUS to geographically remote physicians, and
(2) Provide virtual ongoing live-imaging consultation expertise to Northern or remote communities for continuous quality maintenance. 


Meet the ARCTICA Team

Dr. Amer Johri
Dr. Johri is a clinician scientist within the Department of Medicine, Division of Cardiology at Queen’s University. He is the founder of the Cardiovascular Imaging Network at Queen’s (CINQ), a vital group of highly qualified personnel (HQP) and students; experts in advanced image processing, multi-centre clinical trial deployment, and knowledge-translation. He is highly involved in POCUS Training and Education, working to integrate ultrasound skills at the undergraduate medical student level over the last 5 years.  He has identified and reviewed key commonalities between various POCUS curricula described in published studies, as well as successful and unsuccessful training strategies to serve as a potential outline for initial training and maintaining competency in cardiac POCUS. Dr. Johri is a past Chair of the American Society of Echocardiography (ASE) Circulation and Vascular Ultrasound (CAVUS) Council, and developed the ASE POCUS course, has published guidelines for the use of POCUS in clinical settings, and is an author on the Atlas of Point-of-Care Ultrasound.
Dr. Steven Montague

Dr. Montague is a Clinician-Educator, and Assistant Professor within the Department of Medicine, Division of General Internal Medicine. He has a Bachelor’s of Science in Life Sciences, and a Master’s of Science in Neuroscience. He then graduated medical school at the University of Manitoba in 2013. Subsequently he completed both his core Internal Medicine residency and General Internal Medicine sub-specialty training at Queen’s University. He joined the Division of General Internal Medicine at Queen’s University in 2018. Dr. Montague’s inpatient clinical practice primarily involves clinical teaching units and general internal medicine consults. In the ambulatory setting his practice includes general internal medicine consults, and perioperative care. Dr. Montague’s academic interests include Point of Care Ultrasound (POCUS) and Medical Education. He is convinced that POCUS will soon become as much a part of the bedside assessment as the stethoscope, and is passionately teaching Internists about this powerful tool.

Dr. Salwa Nihal
MD (MBBS), MPhil, MSc

Dr. Salwa Nihal graduated and practiced as a medical doctor overseas but has adopted Kingston as her home.  Due to her experience in medical teaching and research, she has now taken steps to build a career in medical education and research. She did her Master’s degree in Human Physiology (2012) and completed a second Master’s degree in Anatomical Sciences at Queen’s University (2017). Dr. Nihal’s research interests lie in the development of online modules for Cardiac and Lung Point of Care Ultrasound (POCUS) for Medical Schools. She is the author of the first two chapters of E-learning POCUS modules for novel users currently housed on the ASE (American Society of Echocardiography) official website. She has successfully conducted a study for testing the POCUS modules with the medical students at Queen’s, funded by a SEAMO education grant. She is now the Manager, Transitional Institute of Medicine (TIME) in the Dept. of Medicine and continues to collaborate with CINQ on the ARCTICA project.
