Explicitly being turned away? I have not seen those. The New York Times did an analysis of the overall death rate, however, and setting aside COVID deaths, it is up. It's not an unreasonable assumption to assume at least some of those are lack of medical care for whatever reason.
It's because people are afraid to go to hospital or call paramedics, they actually did a mini-campaign over here in the UK telling people it's still ok to call 999 (our 911) because they were so concerned about the deaths happening at home that could have been avoided.
the health system was never "overwhelmed" except for brief periods and in specific locales. My spouse is in healthcare, they have still not recovered their normal census. If anything there will be a huge spike in cancer deaths due to late diagnosis etc as people have stayed away.
I am saying people will die from cancer, because covid kept them out of the hospitals and clinics. Its better now, but back in march thru june many hospitals were laying off staff due to the cancellation of almost all routine procedures etc.

Is it possible there are other issues you're not aware of, and that the people who spend their lives studying and preparing for these situations are?
