What this trial studies

This observational clinical trial evaluates the effectiveness of pharmacogenetic testing (PGx) to tailor mental health treatments for veterans and members of the Canadian Armed Forces and Royal Canadian Mounted Police. Participants, including both psychiatrists and patients, will complete surveys to assess their knowledge and attitudes towards PGx. Patients can choose to opt-in for PGx-guided treatment, which involves sharing genetic test results with their psychiatrists to inform treatment planning. The study aims to gather insights on the integration of PGx in clinical practice and its impact on treatment outcomes.

Why it matters

Potential benefit: If successful, this approach could lead to more effective and personalized treatment options for veterans suffering from PTSD.

How similar studies have gone: While pharmacogenetic testing is a growing field, this specific application in PTSD treatment for veterans is relatively novel and has not been extensively tested in similar studies.
