Monitoring, medication adjustment, and education

Salem Health's anticoagulation clinics are outpatient clinics that provide monitoring, medication adjustment, and education for people on anticoagulation medications.

Although we are located at Salem Hospital and West Valley Hospital, we collaborate with patients of providers across the state of Oregon — not just Salem Health Hospitals and Clinics.

Using our proven process, we’ll lead you through beginning anti-coagulation; managing your medication before, during and after procedures; and routine supervision of your blood levels and medication doses.

At Salem Health, we take care of our patients every step of the way to help you better understand what is wrong and how we’re going to help you toward improved cardiovascular health. Through expert patient education and treatment, we help patients and their loved ones learn more about their care. Our team is centered on your care.

To become a patient of our clinics, you need a referral from a medical provider (MD, DO, FNP, ANP, NP or PA) licensed in Oregon. We may be able to accept referrals from naturopathic doctors, depending on your insurance. Talk to your doctor to see if our clinics can help you!

Medicare and most insurance plans cover the cost of visits to an anticoagulation clinic. Contact your insurance provider to find out about your coverage and any copays or coinsurance fees.

Your first appointment

Your first visit to the anti-coagulation clinic will take 40 to 60 minutes. It also may be in a group setting with other new patients. Please bring your updated medication list to this appointment.

Your other appointments will take 15 to 30 minutes.

During your appointments, we will:

  • Help you get started as a new patient, providing in-depth education.
  • Understand your health history, current medications and diet.
  • Assist you in understanding anti-coagulation therapy and your individual treatment plan.
  • Provide nutrition and lifestyle recommendations.
  • Perform International Normalized Ratio (INR) lab monitoring, via point-of-care (“finger-stick”) or blood draw, and adjust your medication as needed, based on the results.
  • Discuss changes in diet, acute illnesses, and medications that could impact your therapy.
  • Manage anti-coagulation prescription refills to your preferred pharmacy.
  • Coordinate anti-coagulation therapy before and after surgeries and procedures.
  • Provide after-hours care with an on-call nurse available in the evenings, on weekends and holidays.
