This randomized controlled trial will evaluate whether the use of pharmacogenetic testing through a Medication Therapy Management (MTM) program has a beneficial impact on drug therapy problems. More specifically, cytochrome DNA testing, which provides information with regards to participant specific metabolism of medications, will be used in the evaluation of participant medication regimens. The overall aim of the project is to evaluate if the addition of genetic CYP testing to a standardized MTM Program provides increased clinical value. To answer this question, the investigators will look at the drug therapy problems (DTPs) identified by the genetic test compared to those DTPs discovered without the test.
All study participants will receive a Comprehensive Medication Review (CMR). One third will have standard MTM conducted. Another third of the participants will be randomized to MTM plus drug interaction risk analysis via YouScript software. The remaining third will be randomized to MTM along with drug interaction risk analysis via YouScript software and genetic testing. The software will identify polypharmacy patients who may benefit from pharmacogenetic testing based on their current medication regimen. Results of the testing will be mailed to both the participant and their provider. Participants who undergo testing will also receive a follow-up phone call. All participants, including those who receive MTM alone, will receive a contact 3 months later to assess quality of life.

NONE
Enrollment
341
Genetic testing for 2D6, 2C9, 2C19, 3A4, 3A5 polymorphisms
By assessing a patient's medication list along with the frequencies of variant phenotypes in the population, YouScript is able to identify whether a patient might be at risk for an adverse drug event and suggest when testing might be appropriate.
