Abstract

Abstract

Background: Treatment of major depression follows the guidelines from evidence-based medicine established algorithms; however, 50% of patients diagnosed with major depressive disorder do not respond to their first medication trial, and 70% may go through four treatment attempts before achieving remission.

Purpose: To demonstrate the value of pharmacogenomic testing as a treatment-guidance technology in patients with resistant depression and assess healthcare providers' motivation to adopt the technology.

Methods: A retrospective chart review of (N = 73) patients' treatment response measured by the pre-post PHQ-9 depression scale after pharmacogenomic guided medication intervention with descriptive statistics and paired t-test. The project also assessed providers' motivation to adopt and use pharmacogenomic testing by completing the providers' motivation scale (PMA) before and after viewing an educational session on the subject.

Results: A significant improvement in mood with a mean decrease of 10 points in the post PHQ-9 scores ( p = .000 < .001) in 53% of the subjects, and 33% had scores that ranked within remission. Most patients (60%) responded to 1.3 medications post pharmacogenomic treatment. The providers were motivated to learn new technology and gain knowledge derived from current information for patient care.

Conclusions: These are significant findings corresponding to the new evidence research in pharmacogenomics supporting the use of the technology as a therapeutic resource for treatment-resistant depression patients.
