Incidence of emergency calls and out-of-hospital cardiac arrest deaths during the COVID-19 pandemic: findings from a cross-sectional study in a UK ambulance service.

There was a rise in incidence of OHCA and OHCA deaths during the same period; however, these changes appear transient. Further research is required to understand patient behaviour towards seeking help during the pandemic and the long-term consequences of not doing so.
