Personalized Pharmacotherapy Using Pharmacogenetics in Veterans

What this study is about

This study is an observational clinical trial aimed at to evaluate the use of pharmacogenetic testing (PGx) for mental health treatment in members and Veterans of the CAF and RCMP patient population as well as the attitudes of both St. Joseph's OSI Clinic Psychiatrists and patients towards PGx. Both OSI Clinic Psychiatrists participants and patient participants will be administered a brief demographic survey in addition to a survey examining their views on, and current knowledge of PGx. Patient participants will have an opportunity to opt-in to or opt-out of receiving PGx. For patient participants who opt-in to PGx (PGx-guided treatment group), a report summarizing the PGx results will be sent to each patient participants' respective OSI Clinic Psychiatrist, alongside a questionnaire that captures the OSI Clinic Psychiatrist participant's treatment planning and changes to treatment planning. Where applicable, past treatment data from patient participants acquired at the St. Joseph's OSI Clinic will be used to identify the number of prior medication changes. Patient participants who opt-out of PGx but continue to receive pharmacologic care at the St. Joseph's OSI Clinic will act as a standard care comparator treatment group. Patient participant's outcomes including PTSD, depression and anxiety severity, and medication-related side effects, will be assessed until the patient participant is discharged from the OSI Clinic or after 24 weeks, whichever comes first. All patient participants, regardless of their study treatment group, will have their symptomatology collected via standard care data collection protocol (Client Reported Outcomes Monitoring Information System (CROMIS) and electronic medical records (EMR)); a self-report assessing the presence of side effects will be completed via Lawson REDCap. OSI Clinic Psychiatrist participants and patient participants will be asked to complete a virtual exit interview at the end of their participation.
