Not sure if you’re serious but just search the name Kaiser in any research search engine.

Their secret sauce is their ability to standardize protocols throughout their entire organization.

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.

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.

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

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.
