In Florida, a large medical system saw an order for thermometers taken away. And officials at a system in Massachusetts were unable to determine where its order of masks went. “Are they stockpiling this stuff? Are they distributing it? We don’t know,” one official said. “And are we going to ever get any of it back if we need supplies? It would be nice to know these things.” PeaceHealth, a 10-hospital system in Washington, Oregon and Alaska, had a shipment of testing supplies seized recently. “It’s incredibly frustrating,” said Richard DeCarlo, the system’s chief operating officer.
