Re: Margaret McCartney: If screening is worth doing, it’s worth doing well

Chris Mimnagh writes that AF screening has detected people with AF.

This is to be expected. Screening finds things. But this does not prove whether or not the screening results in interventions or actions capable of more benefit than harm, or merely larger lead times, or whether the opportunity cost is rational, or whether this is a cost effective intervention overall.

The involvement of industry and charities supported by industry in facilitating screening for AF while it is not recommended by the UK NSC should be a red flag.
