Participant milestones

Participant milestones
Measure
PGx Only (Patients)
Patients received pharmacogenetic testing only. Participating pharmacist made recommendations for drug/dose changes based on PGx results. Data collected from both patients and pharmacists.
PGx + MTM (Patients)
Patients received pharmacogenetic testing along with medication therapy management (MTM). Two MTM sessions will be conducted: one at the time testing is ordered and the testing sample is collected, and one when results are returned to the patient. Pharmacists made recommendations for drug/dose changes based on medication action plan developed during MTM and the PGx results. Data collected from both patients and pharmacists. Medication Therapy Management: Community pharmacists will provide medication therapy management in combination with pharmacogenetic testing
PGx Only (Pharmacists)
Patients received pharmacogenetic testing only. Participating pharmacist made recommendations for drug/dose changes based on PGx results. Data collected from both patients and pharmacists.
PGx + MTM (Pharmacists)
Patients received pharmacogenetic testing plus medication therapy management (MTM). Participating pharmacist made recommendations for drug/dose changes based on PGx results and conducted MTM. Data collected from both patients and pharmacists.
