The reason the delivery of office visits hasn't changed since the 1950's is because the supply is constrained by huge barriers to entry, the demand keeps increasing, and the legal exposure and regulatory burden on the transaction keeps increasing.

There is simply no incentive to do it "better".

Group visits have a very limited usefulness.

There are fads in every discipline. The writer is probably not in healthcare. Other businesses' fads always look more viable than your own.

One of the things that seems new (to me, at least) is the increasing use of "nurse practitioners" to handle some of the cases in our doctor's office. This is a way to increase the supply of medical care, though it doesn't necessarily go down well with some of the patients I've talked to.
