Olympic Physicians has been recognized for our involvement and leadership in Quality Improvement. We have partnered with the Washington State Department of Health and Qualis Health to develop and maintain a program that helps our diabetic patients improve the lives they lead. This program includes a computer registry that allows us to follow up with our patients and give feedback to our providers about the care they are giving compared to their piers. Olympic Physicians was chosen by our partners because of our success and was published in the attached article on Quality Improvement.
