As an Health care professional I'm part of a team who run Pacemaker clinics. We clearly know we have patients who are living abroad.
We have a responsibility to ensure they are safe, however if we are aware they live overseas, we now have to inform, our admin team who action some form of notification as they have no GP.
Not sure of the process but it is getting notified.
Not that long ago a chap had his ICD ( internal Cardiac Defibrillator) go off.
He couldn't get anyone to check it, he was living most of the year aboard , so he decided to fly back to the UK to see us, on a 10 hour flight.
Normally you need to present yourself at a Hospital ASAP , this is serious stuff, he was lucky he made it back, safe.
When he arrived he stayed with his Son, and used that address.
We did feel sorry for the Aircrew, if it had gone off again? Outcome might have been good.
