Follow Through With Disclosure
48 Participants

PRIMARY outcome

Timeframe: From the initiation of bioinformatics analysis to disclosure of confirmed actionable genetic finding (approximately 6 months).

Population: Implementation costs included the effort and resources needed to screen the existing genetic data for 7,603 FHS and JHS participants for actionable genetic findings.

We will determine the costs and associated time demands of implementing gRoR using a microcosting approach in which study staff track the amount of time they spend and the resources they use for each step of the protocol. Ranges are based on 50% to 200% of point estimates given variability in wages and prices of services.

OTHER_PRE_SPECIFIED outcome

Timeframe: 6 months Post-Disclosure Survey (6-9 months after disclosure of confirmed results)

Population: Participants with confirmed and disclosed actionable genetic findings who completed the 6 month follow up survey. Only living participants identified with actionable genetic results that were confirmed and disclosed to their health care provider were asked to complete surveys.

The survey assessed the disclosure-specific impact of information on distress and positive emotions using an adapted 12-item version of the FaCTOR, a validated instrument developed for genomic sequencing that is sensitive to responses to high- and low-risk genetic risk results. Subscales assess negative emotions (range: 3 to 15), positive feelings (reverse-scored, range: 4 to 20), uncertainty (range: 3 to 15), and privacy concerns (range: 2 to 10), with higher scores on each subscale indicating more negative experiences.

Serious Adverse Events were defined as instances where patients received major interventions (e.g., prophylactic surgery, placement of a pacemaker) based on an erroneous finding. Other adverse events were defined as instances where information had been misstated and corrected (e.g., reporting of a carrier status for a recessive condition as risk for a dominant condition).
