MALTA — A new $17.5 million medical facility at Northway Exit 12 is part of a growing trend in the way health care is offered to local communities. Malta Med Emergent Care, a collaboration between Saratoga and Albany Medical Center hospitals, offers emergency-room type treatment for a variety of illnesses, from strokes and heart attacks to abdominal pain, flu, fever and allergies. Last October, Schenectady-based Ellis Hospital opened a similar, $18 million facility near Exit 9 called the Medical Center of Clifton Park. "Our goal is to provide the care people need close to home," Ellis spokesman Matt Van Pelt said.
