Genetic Counseling Clinical Trial
Official title:
Randomized Clinical Trial of the Sequence of Genetic Counseling and Testing to Optimize Efficiency, Patient Empowerment and Engagement, and Medical Adherence for Diverse Genetic Testing Indications
Although pre-test genetic counseling is widely recommended and has come to dominate genetic counseling practice, tailored results-focused genetic counseling could both increase genetic counseling efficiency and improve genetic counseling outcomes for the growing number of patients seeking genetic testing for recommended genome-guided medical management. This study will test that hypothesis in adults referred for cardiovascular genetic counseling and testing at the Johns Hopkins Center for Inherited Heart Diseases. This study is a three-arm randomized clinical trial to evaluate two complementary approaches to shifting the primary genetic counseling session to post-test for 510 adults with two broad cardiovascular genetic counseling indications: diagnostic panel testing and family-specific variant testing. The investigators will compare usual care (pre-test genetic counseling appointment, results returned by phone / electronic health record) with online video-based pre-test tailored genetic education with an optional (efficiency arm) or required (flipped arm) phone call with a genetic counselor followed by a post-test genetic counseling appointment. The investigators hypothesize that post-test genetic counseling will: 1) increase efficiency, 2) promote patient empowerment and adherence, and 3) have similar genetic test-associated psychosocial impact.
This is a three-arm randomized clinical trial with a parallel-group design comparing usual care (pre-test genetic counseling, test results by phone/electronic health record (EHR)) to two approaches to post-test results-focused genetic counseling involving a pre-test educational video with an optional [efficiency arm] or required [flipped arm] phone call with a genetic counselor followed by a post-test genetic counseling appointment. Consented participants will be randomly allocated to the three study arms stratified by genetic testing indication (cardiovascular panel, family-specific variant). Questionnaires will be administered at 4 timepoints: 2 weeks before pre-test education/counseling (Q1), immediately after pre-test education/counseling and test ordered or declined (Q2), 2-weeks post-disclosure (Q3), and 6-months post-disclosure (Q4) (Aims 1-3). Data will be extracted from each participant's electronic health record (EHR) to record potential clinical covariates (Aims 1-3), validate self-reported adherence to medical recommendations (Aim 3), and obtain metrics to measure genetic counseling efficiency (Aim 4). ;
