Before coronavirus, I was seeing a nurse every month for a routine check-up - blood, blood pressure, weight, an ECG if my doctor decided it was called for, etc. This was one of the conditions for me getting away from secondary care in 2016, and I was fine with it. I only saw my GP for a review every six months or so or if I had a concern I needed to talk with him about.
I tend to schedule my dentist and hygeinist on the same day once every six months - I'm on a DD, so I pay for 2 appointments annually for both - and I get a letter from my optician every 2 years to remind me I need to book an appointment to see them. My hypnotherapist is as and when, but it's monthly Zoom right now.
The last time I was at a medical facility was...mid-March, I think? My local surgery has been closed for general visits since April, and I wouldn't even consider going into a hospital because I'm terrified of them. My dental practice is supposed to reopen at the end of the month but I won't be going in there.
