US hospitals are at historic capacity and require unprecedented rationing. As it continues, tens of thousands will die (that otherwise wouldn't have) : UnpopularFacts

Americans are being transported hundreds of miles from their homes because no nearby hospital has room for them. Some have even died waiting for medical attention.

In other words, US hospitals are being forced — in the middle of a public health emergency — to ration health care for their patients.

Surges in COVID-19 cases have stressed hospital systems, negatively affected health care and public health infrastructures, and degraded national critical functions. Resource limitations, such as available hospital space, staffing, and supplies led some facilities to adopt crisis standards of care, the most extreme operating condition for hospitals, in which the focus of medical decision-making shifted from achieving the best outcomes for individual patients to addressing the immediate care needs of larger groups of patients.

The negative binomial regression model used to calculate estimated deaths predicted that, if intensive care unit (ICU) bed use nationwide reached 75% capacity an estimated 12,000 additional excess deaths would occur nationally over the next 2 weeks. As hospitals exceed 100% ICU bed capacity, 80,000 excess deaths would be expected in the following 2 weeks. This analysis indicates the importance of controlling case growth and subsequent hospitalizations before severe strain.
