San Antonio Express News, Feb. 8, 2007 SAN ANTONIO - For sick employees at Morningside Ministries, the question isn't whether the doctor is in, but if the doctor is on.Workers at the four elder-care residences in San Antonio and Boerne can meet with virtual in-house doctors for everything from flu to high blood pressure. They sit on exam tables facing a monitor on which they can see the doctor. On the other end, the doctor in Galveston can meet face to face with the patient while getting close-up images of skin, ears and throat.   Morningside Ministries, with a $150,000 grant from the AT&T Foundation, now has all its locations wired to serve employees, many of them caregivers without insurance. The grant covers the cost of the equipment, a high-speed connection, a registered nurse who travels between sites, a licensed vocational nurse at each location and a doctor affiliated with the University of Texas Medical Branch at Galveston.
