The COVID-19 BreastScreen Department - beyond the pandemic.

The first wave of the COVID-19 pandemic in Australia forced a temporary closure of BreastScreen Australia services. Now reopened, the BreastScreen experience has been redefined for both staff and clients and the journey to the 'new BreastScreen normal' is continually evolving in response to the ongoing threat of COVID-19 and government directives on health policy. Many changes mirror those undertaken in the wider community and emphasise wellness to attend, hygiene and social distancing.

COVID-19 impact on undergraduate teaching: Medical radiation science teaching team experience.

The COVID-19 crisis has caused a number of significant challenges to the higher education sector.

The masked educator-innovative simulation in an Australian undergraduate Medical Sonography and Medical Imaging program.

Introduction: Clinical learning experiences for sonography and medical imaging students can sometimes involve the practice of technical procedures with less of a focus on developing communication skills with patients. Whilst patient-based simulation scenarios have been widely reported in other health education programmes, there is a paucity of research in sonography and medical imaging. The aim of this study was to explore the effectiveness of Mask-Ed™ (KRS Simulation) in the learning and teaching of clinical communication skills to undergraduate medical sonography and medical imaging students.
