SAN FRANCISCO — Leveraging pharmacogenetics for selecting treatments may benefit patients with treatment-resistant schizophrenia and other psychotic disorders, according to a retrospective chart review  presented at the American Psychiatric Association Annual Meeting, held May 18-22, 2019, in San Francisco, California.

Researchers compared outcomes in individuals admitted to inpatient psychiatric units who were given genetic testing with those who were not. Pharmacogenetics can be used to improve treatment adherence which may be affected by drug side effects. The participants’ clinical features were reviewed, as were their metabolic parameters, choice of medications, length of stay, care after hospitalization, and rate of readmission. Study outcomes included  clinician adherence to recommendations for pharmacogenetics testing, patient compliance to the recommended treatment, and rate of readmission, indicative of treatment success.
