health insurance solvency ratio, should I care?

I was checking the new listings on comparis and found a database of insurance financial results.

For example: Sanitas basic and supplemental health insurance |

Should I care provided that I’m not opting for any supplemental health insurance?

There are some smaller insurances available in Zurich. I wonder what should I consider before changing the provider. Is basic health insurance covered no matter what from the patient point of view, even if the health insurance goes under water?

There is an “Insolvenzfonds” for basic health insurance, which should cover services if a (basic) health insurance goes bankrupt.…-aufsicht.html

The cases I know of the failed companies were taken over by larger ones which continued to offer the policies on the same terms and prices.

Sometimes the policyholders even got a cash payout after the financials were finalised.
