I would recommend Kaiser coverage to anyone thinking about switching from one of those plans with big increases. Their doctors don't get extra money for performing extra procedures as is the case in a lot of plans, so there is more incentive to just do what's necessary.
Would that mean that they would send the patients back home unless they can provably identify some issue? (This has happened to me a few times (with the issue re-discovered at a later point), though I have never been with Kaiser.)
Some of the Kaiser doctors are more evidence-based than others. But none of them take home more money if, for example, they operate on your rather than not. That is still true in many plans, even high-end ones, though they're not going to tell you about it.
