WELL, AT LEAST YOU’D BE LESS LIKELY TO CATCH SOMETHING: Going to the Emergency Room Without Leaving the Living Room. “When Mrs. Vitale falls or seems lethargic or short of breath, her aides no longer call 911. They dial the House Calls service at Northwell Health, the system that includes Long Island Jewish Medical Center and that dispatches what it calls community paramedics. They often arrive in an S.U.V. instead of an ambulance. And with 40 hours of training in addition to the usual paramedic curriculum, they can treat most of Mrs. Vitale’s problems on the spot instead of bustling her away.”
