Pharmacogenetic Testing in Primary Care

This study has been completed.

The purpose of this study is to further integrate pharmacogenetic (PGx) testing into clinical practice by educating physicians about pharmacogenetics and offering testing to their patients. Pharmacogenetic testing may help physicians choose the best drug and dosage for their patients which can reduce side effects, increase effectiveness, and improve patient adherence.

Two clinics will be involved. One clinic will have a pharmacist on-site as a resource to physicians and to advise what patients may benefit from PGx testing; the other clinic will have a pharmacist on call.

Patient and physician perspectives about PGx testing and their utilization will be examined via surveys.

The investigators hypothesize that with education about PGx testing, more physicians will utilize testing.
