Medical tents for vaccinations are set outside the Children's Hospital Los Angeles Friday, Dec. 18, 2020. Increasingly desperate California hospitals are being "crushed" by soaring coronavirus infections, with one Los Angeles emergency doctor predicting, that rationing of care is imminent. The most populous state recorded more than 41,000 new confirmed cases and 300 deaths, both among the highest single-day totals during the pandemic. In the last week, California has reported more than a quarter-million cases and 1,500 deaths. (AP Photo/Damian Dovarganes)

FILE - This Friday, Sept. 30, 2011, file photo shows the emergency room entrance at the Henry Mayo Newhall Memorial Hospital in Santa Clarita, Calif. In hard-hit Los Angeles County, Nerissa Black, a nurse at Henry Mayo Newhall Hospital, estimated she's been averaging less than 10 minutes of care per patient every hour. That includes not just bedside care, but donning gear, writing up charts, reviewing lab results and conferring with doctors, she said. "And the patients who are coming in are more sick now than they've ever been, because a lot of people are waiting before they get care. So when they do come in, they're really, really sick," Black said Sunday, Dec. 20, 2020. (AP Photo/Jason Redmond, File)
