Medical Home

What’s up at Olympic Physicians?

Turns out, a lot. At Olympic Physicians, we've rolled out a new way of caring for patients called "medical home." We're putting patients at the center of a doctor-led team of health professionals who deliver better health care, for lower cost.

The goals of the medical home model are better health and health care for patients, and lower health care costs. Olympic Physicians was selected to partner with the State of Washington to develop and test the medical home program in the State of Washington. As one of very few clinics selected we have had the opportunity to learn from experts well known in the field of health care quality improvement.

Olympic Physicians made a significant commitment and investment to the medical home model, hiring new clinical staff. Patients get better care from their primary care team, which ultimately means they make fewer visits to the emergency room and hospital, the places that usually take the biggest bite out of the health care dollar.

A Closer Relationship With Patients

The heart of the medical home is health care managed and coordinated by personal providers — the quarterbacks, as it were — and their teams, which can include nurses, physician assistants, advanced nurse practitioners, and medical assistants.

Your personal provider and their team members are more actively involved in the patient's care than before. For instance, a medical assistant might periodically call patients with chronic diseases, such as diabetes, to check blood sugars, discuss foot care, or ask about eye exams. We have developed office wide protocols that remind providers, medical assistants when you may be due for certain tests or appointments. We want to help you improve your health. We understand that what happens in your life after you leave the office makes a difference in your health.

Olympic Physicians has an emphasis on preventive care and keeping patients healthy. In the medical home, part of that prevention strategy plays out like this: Whenever patients schedule an office visit, a member of the medical team goes through their records and flags needed tests or other preventive care measures. The team member may call you to schedule these additional tests or your provider may talk to you at your scheduled appointment. A patient who comes in with a bad cold might be surprised when her doctor says she's due for a pap smear.

Another key component to medical home at Olympic Physicians is electronic medical records that give everyone involved in a patient's care, including the patient, instant access to critical information such as test results, prescriptions, and medical history for a patient. Olympic Physicians offers patient's complimentary access to their electronic medical records. You can securely message the receptionist for an appointment or the medical assistant to get your medication refilled. To find out more, ask any staff member at your next visit.

We look forward to working together with you and your family to help you live a healthier life.
