This study focuses on identifying and promoting the most effective care for long COVID patients, ranging from accurate assessments in specialist clinics to the best advice and treatment in surgeries, as well as home monitoring methods that can show flare-ups of symptoms. Drawing from the experiences of current long COVID patients and NHS professionals, the research aims to establish a gold standard of care that can be shared across England and the rest of the UK. Analysis will be conducted in 10 long COVID clinics, at home and in doctors' surgeries, and the study will track referrals and evaluate different services through patient interviews to make sure they are efficient, accessible and cost-effective. Specialists in healthcare inequality will also ensure that views are sought and recorded from people who are not visiting clinics.
