Sustainable low-field cardiovascular magnetic resonance in changing healthcare systems.

Cardiovascular disease continues to be a major burden facing healthcare systems worldwide. In the developed world, cardiovascular magnetic resonance (CMR) is a well-established non-invasive imaging modality in the diagnosis of cardiovascular disease. However, there is significant global inequality in availability and access to CMR due to its high cost, technical demands as well as existing disparities in healthcare and technical infrastructures across high-income and low-income countries. Recent renewed interest in low-field CMR has been spurred by the clinical need to provide sustainable imaging technology capable of yielding diagnosticquality images whilst also being tailored to the local populations and healthcare ecosystems. This review aims to evaluate the technical, practical and cost considerations of low field CMR whilst also exploring the key barriers to implementing sustainable MRI in both the developing and developed world.

Recorded infection control messages delay inter-professional communication but are not associated with COVID-19 prevalence or mortality: insights from a national switchboard analysis.

Appropriate dissemination of information to the general public is a key component of the pandemic response. In 2018, recorded infection control advice messages were affixed to 30% of England's automated hospital switchboards during the seasonal influenza and norovirus outbreaks. As the majority of messages were mandatory for all callers, healthcare professionals using the hospital switchboard - including during time-critical emergencies - had their enquiries significantly delayed by these measures. Importantly, published analyses did not demonstrate an association between these messages and patient outcomes. As of May 2020, 85% of NHS trusts made use of infection control messages; on average, these delayed healthcare professionals by 59.4 seconds per call, but had no clear association with patient outcomes from COVID-19. An ongoing national switchboard quality improvement project seeks to establish a gold standard whereby healthcare professionals with urgent enquiries can press 'X' to skip past infection control messages and have their calls triaged immediately.
