While the ultimate goal of this project is to show an improvement in patient outcomes, this pilot study will be used to evaluate the feasibility of introducing the pharmacogenomic algorithm to a new setting that does not routinely use the algorithm. Secondary outcome data will be collected to generate meaningful estimates of the magnitude of potential treatment effects. The trial is designed to occur within the Franciscan Skemp Healthcare System in La Crosse, Wisconsin and Arcadia, Wisconsin over the course of 12 months. A novel method of delivering the genetic testing results to the physician will be utilized and evaluated. This novel method is a system which will deliver results faster and give more guidance for the selection of medication.

Algorithm provided to physician to assist with medication decisions.
Genetic test results was put through algorithm and provided to physician for guidance prescribing medication.
No Intervention: No Algorithm
Algorithm was not provided until after the eight weeks of study.
Antidepressant medications are among the most widely prescribed medications. However, only 35% to 45% of depressed patients have a complete remission of their illness when initially treated with these medications. Consequently, the Mayo Clinic psychiatric pharmacogenomic team has developed a pharmacogenomic algorithm that has been designed to improve the effectiveness and safety of antidepressant medications by providing guidance in medication selection and appropriate dosing. This algorithm has been incorporated into a new genotyping interpretative report. This report is now available from AssureRx. The pharmacogenomic algorithm is based on genotyping both copies of four informative genes. These four genes are: 1) the Cytochrome P450 2D6 gene; 2) the Cytochrome P450 2C19 gene; 3) the Serotonin Transporter gene (SLC6A4); and 4) the Serotonin 2A receptor gene (5HTR2A). Though this algorithm is not yet part of the universal standard of care, Mayo clinicians have found it helpful in guiding treatment decisions at Mayo Clinic Rochester.
