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.
