innesota hospital leaders are warning in a full-page newspaper ad that they are “overwhelmed” amid a COVID-19 surge and are urging the public to take action. “Our emergency departments are overfilled, and we have patients in every bed in our hospitals,” write the leaders of nine hospital systems in the state, including the Mayo Clinic and North Memorial Health. The hospitals warn that because their capacity is strained, care for non-coronavirus medical events, like heart attacks, is also threatened.
