We expect to share additional study results later this year.” The study demonstrated that the percentage of patients with hospitalizations was significantly reduced 180 days after GeneSight testing: 39% relative reduction in psychiatric-related hospitalizations. 29% relative reduction in hospitalizations for any reason. Significant reduction in hospitalizations for patients who were switched from a medication with a significant gene-drug interaction to a medication with no or moderate gene-drug interactions. The study found that, among patients who took the GeneSight test, there was a decrease in the proportion of patients who were prescribed medications with significant gene-drug interactions after taking the test: The percentage of patients who were prescribed medications in the significant gene-drug interaction category was reduced from 26.1% to 15.9% The percentage of patients who were prescribed medications with no gene-drug interactions increased from 27.5% to 47%. “These data suggest that healthcare providers are using the GeneSight test to make medication decisions in the real-world,” said Holly Johnson, Ph.D, director of medical affairs at Myriad Genetics. “These results are consistent with multiple, prospective studies demonstrating the utility of pharmacogenomic-guided treatment for improving response and remission rates in major depressive disorder.” About the Poster Title: “Impact of Combinatorial Pharmacogenomic Testing on Hospitalization Rates in a Real-World Dataset of Patients with Major Depressive Disorder” Authors: Andria L. Del Tredici, PhD; Priya Maheshwari, MS, RPh; Alexander Gutin, PhD; Devika Chawla, PhD; Katie Johansen Taber, PhD; Holly L. Johnson, PhD; Andrew A. Nierenberg, MD Presenter: Priya Maheshwari, MS, RPh, senior medical information liaison at Myriad Genetics Conference: American Association of Psychiatric Pharmacists (AAPP) conference in Orlando, FL; presented on Monday, April 8, 2024 About the Study The study analyzed a data set generated by linking more than a half million de-identified patients who received the GeneSight test to administrative insurance claims from a nationwide data warehouse in the United States. Nearly 21,000 depressed patients met inclusion criteria to be in the study. The study authors then evaluated this data set with regard to medications prescribed before and after GeneSight testing, as well as hospitalization rates before and after GeneSight testing. Future analysis of the data will include investigating the impact of post-PGx medication selection on total cost of care for depression.
