James Hoevelmann of Sullivan, Missouri, used to work in hospital construction. But these days, even though he suffers from severe chronic obstructive pulmonary disease, the retired carpenter, 74, doesn't want to go anywhere near a medical facility. And he doesn't need to, even though his COPD has been bad enough in the past to regularly land him in the emergency room and the intensive care unit. The reason: Hoevelmann now gets his care from Mercy Virtual Care Center some 50 miles away in Chesterfield.
