Patient-centered medical homes (PCMH) have gained popularity in recent years, yet questions remain about their effectiveness. The PCMH approach revolves around a team of medical and health professionals who, working together, treat an individual, led by a primary-care physician who orchestrates the entire effort. In a new study, researchers at the University of Iowa evaluated a similar model being tested with military veterans and conclude that maintaining a direct, regular channel of communication between the patient and the primary doctor is critical to success.
