Are we talking primary care visits? Who doesn’t schedule them? Are there any countries where you can just walk into a doctor office and they magically have your tests and records just ready in-hand? Of course not, you make appointments. Same with operations and other medical procedures.

In my province in Canada we have digital records. While there are some hiccups as a couple of systems merge to one I can see a doctor in the emergency room and then go see my GP the next morning and both the emergency room staff and my GP have access to all of my tests and records.

There are still issues with long waits but in my experience if you have a long wait its because your issue is not extremely urgent and while waiting sucks its better than needing the care urgently.
