Study is from 2000-2013, their care has deteriorated significantly since then. I know because I've been a patient the whole time.

Their quality metrics have increased steadily over the last 10 years

There’s no best healthcare for everyone but that doesn’t change the fact that Kaiser is objectively one of the best.

I agree. The last 5 years especially.

Well then their protocols suck. I have many anecdotal data points about them fumbling in major ways when it matters (missed major pathologies, messed up surgeries, etc.).

If you have a choice of hospital networks, research carefully. Kaiser might be fine for many people's needs, it's not fine when it comes to intensive care.

Correct. There’s no uniform healthcare solution that works for everyone.

But it doesn’t change the fact their protocols are top notch as reflected by their quality metrics.

That’s the measure for one pathology, but in terms of a provider comparison, what’s the measure? It isn’t dollars versus life span or morbidity.

Why wouldn't I be serious? And everyone lives in and cares about California.

Plus, a quick Wikipedia glance shows they have a fair share of controversies, including major fines due to poor COVID protocol adherence.
