Shortly before Obamacare I went to the same variety of specialist in that closer city. I called on a Monday and was in to see him on Thursday morning. Now, the three closest clinics to me have no doctors at all between them, just nurse practitioners and physician assistants. If your condition isn't on their short script you get an appointment in six months with a different nurse, or directions to the emergency room. I'm not claiming this is the general experience, but my experience has vastly enshittified.
The specialist nurse that took me six months to see? He ordered a test and scheduled me to come back and discuss it with him in another six months. Maybe I'll get another five minutes of his time then.
Basically, if you want really good healthcare, you need to live in or near a very large city. (Albuquerque is not a very large city.)
Another thing that's probably changed in the US is larger healthcare companies taking over doctors' practices and enshittifying them to increase profits. Doctors are happy to sell because they're getting close to retirement, and/or tired of dealing with all the administrative hassle on top of actually being a doctor and caring for patients. I've read about this type of thing greatly affecting veterinary care in the US too.
As another commenter said, there’s been an exodus of specialists from rural areas. This is a global phenomenon, not limited to the US.
They are then finding out that for profit businesses have no interest in re-hiring all the workers they had before the pandemic, because they didn't lose as much business as they saved money in salary, so everyone is just running a skeleton crew that they overwork.
Meanwhile the data I find for emergency room visits are that there's barely been any increase in percentage of the population that visited an emergency room since 1997.
Companies are spending less on services and letting us just suffer because we don't have better options and YET AGAIN dumb Americans for some reason blame the government for completely independent companies making self serving choices?!
