I remember as a small child in the late 60’s/early 70’s we had a family doctor that would regularly stop by the house for check ups, allergy shots and wellness checks. We rarely went to his office unless it was a new illness or non life threatening emergency.
I miss those days, I also think the doctor enjoyed my grandma’s company and baked goods (but thats a different discussion)
I did not have that experience here, but when I was in Italy, they did have doctors come to people’s homes. I can only remember a couple of times since I was so young.
