Investigating the impact of screen-sharing visual aids during genomic results disclosure via telehealth in diverse families in the TeleKidSeq pilot study.

Purpose: Telehealth genetic counseling is comparable to in-person visits in terms of satisfaction, knowledge, and psychological outcomes, but using visual aids can be challenging on telehealth platforms. This pilot study assessed if the "screen-sharing" feature via Zoom to display visual aids during results disclosure session positively impacted parental experience and comprehension of their child's genomic results especially in underrepresented groups and those with limited English proficiency.

Methods: In the TeleKidSeq pilot study, 409 children with suspected genetic conditions underwent genome sequencing. Families were randomized to receive genomic results via televisits with (ScrS) or without (NScrS) screen-sharing of visual aids. Spanish- or English-speaking parents/legal guardians completed surveys at three timepoints to assess perceived and objective understanding, perceived confidence, and telehealth experience. Regression models evaluated the effect of screen-sharing over time.

Results: Overall, understanding and telehealth experience ratings were high, with no significant differences between the ScrS (N = 192) and NScrS (N = 200) arms with regard to perceived (p = 0.32) or objective (0.94) understanding, confidence (p = 0.14) over time, or telehealth experience (p = 0.10). When stratifying by sociodemographic characteristics and type of device used during results disclosure, we observed subtle differences in the effect of screen-sharing within some sub-groups.

Conclusion: While screen-sharing had no significant impact on overall outcomes, we identified modest effects of screen-sharing within population groups that highlight the need for tailored communication strategies to ensure diverse, multilingual communities derive equitable benefit from telehealth-based genomic results disclosure. Future research is needed to determine whether certain types of visual aids best enhance genomic results disclosure in larger, more robust studies designed to detect smaller effects and subgroup differences.
