There's a bit of that popping up in the west coast too. Some people actually really like it, supposedly like a return to "how it used to be" with your doc making home visits and seeing you in the hospital instead of just having the hospital docs do it, i think most of them are available by phone basically around the clock for their patients too.
From the primary care doc's perspective, i asked my PCP abt it actually recently - He said doing outpatient medicine has basically been ruined and it is god-awful. He told me he has like a 3" stack of paperwork that he works on every day and it never goes away and that's seperate from his online messaging requirements. Its really hard to have an independent practice nowadays so he regretfully works for a huge group and they have all kinds of metrics and goals he's supposed to meet for patient volume. Insurance companies and mega-corp hospital groups have driven this. You know a Kaiser doc is supposed to spend 11 mins per patient? But if they sit down, the patient will perceive the visit as being longer (true story). My doc said the majority of his day is paperwork, not actually spending time w his pts.
I suspect the concierge model is going to become more popular. I also think its like a blowback to all the BS requirements and metrics from insurance companies and hospital corporations. From my understanding patients are less and less satisfied and the primary care docs are generally super burned out. My doc is my age (40s) and told me he wishes he had done just abt any other career. Fucking sad
So the concierge doc says fuck insurance companies and 11 minute visits. I'll manage 300-500 patients (a standard practice is more like 2-2,500 patients) and just take cash payment.
