Extended Follow-Up In The Cogent Study: A Randomized Study Of In-Person Versus Telephone Disclosure Of Cancer Genetic Test Results.

1504Background: Alternative delivery models are needed in the era of Precision Medicine given a shortage of genetic providers and increasing utilization of genetic testing. Telephone disclosure (TD) of genetic test results, including multi-gene panel testing, is non-inferior to usual care in-person disclosure (IPD) for short-term distress but failed non-inferiority for knowledge. Longitudinal data including health behaviors are needed. Methods: 970 patients undergoing clinical genetic testing at 5 centers were randomly assigned to usual care IPD (n = 497) or TD (n = 473) of results in the COGENT Study (NCT01736345). Participants completed surveys after pre-test counseling, post-disclosure and at 6 and 12 months. We used non-inferiority tests for primary analyses and T-tests and logistic regressions for secondary analyses. Results: TD was not worse than IPD for anxiety both post-disclosure and at 6 months, but did not reach the non-inferiority threshold for knowledge at either time point. In secondary anal...
