20th Medical Group announcement Published Feb. 18, 2014 By 20th Medical Group 20th Medical Group SHAW AIR FORCE BASE, S.C. -- Access to Care (Primary Care Appointments) will be limited Feb. 25-28. The 20th Medical Group Primary Care Teams will be undergoing Patient-Centered Medical Home training. Training will enhance the delivery of health care services, increase continuity of care and improve patient satisfaction. If you are a patient assigned to our Family Health Clinic or have children assigned to the Pediatric Clinic, there will be challenges booking appointments beyond 24-HR ACUTE care, care is that which is considered "Urgent" but not an "Emergency," during this brief time period. Thank you for your patience and understanding as we consistently strive to improve our health care services at Shaw Air Force Base.
