Purpose: Pharmacogenomic testing for medications is an emerging science providing new ways of optimizing personalized medicine and provide better pharmaceutical care. There are a wide variety of medications that have specific genotype and phenotypes that can give medical providers assistance in medication selection. Medications that are metabolized by the cytochrome P450 system are often the target of genetic reporting. Oftentimes, this includes mental health and opioid medications. Commercial testing is available for these classes of medications. Testing for these classes can help prevent adverse events and save patients money by choosing optimum therapy at the start of treatment.
Methods: Patients receiving pharmacogenomic testing have failed on previous medications or have other intolerances or allergies to medications. Patients may also be on multiple medications that are at high risk of experiencing medication interactions. Patients electing to receive genetic testing undergo a buccal swab in the family medicine office. This testing is then submitted to the genetic company and once completed, results are available via patient portal. Results typically take between 1 to 2 weeks. After that time, the patient is seen in clinic with provider and pharmacist to review results and to determine the best choice of therapy based on these results. Medical providers in the clinic include D.O, M.D., CNP and first year medical residents.
Results: No additional revenue is brought into the clinic with genetic testing. Having the pharmacist available to review results with the patients allows for the provider to have more time to see other higher complexity patients that result in higher billing codes (99213-99215). The ambulatory pharmacist serves as the interpreter and recommends therapy to the provider. This improves patient’s quality of life and results in decreased side effects from medications. Using pharmacogenetic testing allows for the patient to receive better therapy personalized for them and results in better use of their copay allotment.
Conclusion: The use of pharmacogenomic testing presents as a novel way for pharmacist to assist in medication selection. Not only does the use of this testing help to make better medication decisions but also to help direct counseling on medication therapy. Pharmacogenomic testing resulted in better control of symptoms and better outcomes reported by patients. The role of a pharmacist in this capacity allows for better use of billable provider time.
