Over the weekend, staff at MidMichigan Health-Alma tried to find critical care beds for patients in need. They didn’t find any in Michigan. Nor Toledo. Nor Fort Wayne. “This is real and it’s really serious,” said Marita Hattem-Schiffman, president of MidMichigan Health’s central region. The facilities she oversees include the hospitals in Alma and Clare and the emergency department in Mt. Pleasant.
