As a patient, post-2020 I find even basics like appointment scheduling to be hard. (I'm also an MD, which makes all of this easier for me, and yet it's still a morass of scheduling hell, too many phone calls, too many logins/reauthentications, etc.)
Even things like my yearly checkups which technically doesn’t need an MD, have gone poorly. One of the NPs strongly wanted me on statins of slightly elevated cholesterol meanwhile the MD that I eventually took a second opinion from, suggested that for my age and physical condition, I most definitely don’t need to be on them.
I actually ended up finding a new PCP in the next state over. It's a 10hr drive one way to see them, but when adding up the time, travel costs and other expenses, it's still cheaper than most of the concierge health services in my area.
Same with mental health care. Tried to find a therapist, literally everyone booked out 18 months, many just said no, not taking new patients.
But at least we don't have death panels amirite?
(I was also younger, so had fewer things to talk to my doctors about...)
Anecdotally, though, it seemed like a lot of healthcare providers at the time moved to having better online appointment systems and remote visits, which made scheduling a lot easier for me. Probably a heavily YMMV situation though.
