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.)
Although access got much worse in 2020, my impression is things are back to about what they were in 2019, which is still bad. My memory is that scheduling first became a serious issue when many doctors took early retirement to avoid dealing with the effects of the ACA. If you ignore the COVID bump, how would you describe the changes in accessibility from about 2014 until now?
(I was also younger, so had fewer things to talk to my doctors about...)
