SAN MATEO, Calif.–(BUSINESS WIRE)–Primary care physicians (PCPs) need to become more active participants in treating the Top 10 medical conditions with significant practice variations. “Nationally, PCPs are solely involved in treating less than 25% of medical condition episodes with the most practice variations,” stated Dr. Douglas G. Cave, President of Cave Consulting Group (CCGroup). “And these medical conditions – such as low back pain, degenerative joint disease, headaches, sleep apnea, cataracts, and heartburn – drive well over 50% of all potential patient cost and quality improvements.”
