Patient priorities for a digital health platform to support Lynch syndrome surveillance and research engagement: A needs assessment survey.

e22556 Background: Lynch syndrome requires lifelong, multi-organ surveillance and ongoing family communication to enable cascade testing. Despite established surveillance guidelines, patients with Lynch syndrome often lack integrated, patient-centered tools to coordinate screening, prepare for clinical encounters, and engage in research. Precision Insight is a patient-led digital health community in development to support hereditary cancer families in these tasks. We surveyed Living with Lynch workshop alumni to prioritize platform features. Methods: A voluntary, de-identified online survey was emailed to 60 prior Living with Lynch Workshop participants. Respondents selected their top three tasks the platform should make easier and rated proposed features on a 1–5 scale. Survey items were informed by prior Living with Lynch workshops and patient advisory input. Descriptive statistics are reported. Results: Twenty-nine participants responded (48%). Most identified as a person with Lynch syndrome (25/29, 86%); 17/29 (59%) were cancer survivors and 8/29 (28%) previvors. Top priority tasks were screening planner + reminders (24/29, 83%), research/registry explainers and interest sign-up (20/29, 69%), moderated peer forums (17/29, 59%), private family coordination hub (15/29, 52%), and clinic-visit preparation tools (14/29, 48%). Highest-rated features were screening planner reminders (mean 4.52/5; 26/29 rated 4–5) and clinic-visit prep tools (mean 4.24/5; 23/29 rated 4–5), followed by micro-learning (mean 4.00/5; 22/29 rated 4–5) and peer forums (mean 4.07/5; 20/29 rated 4–5). Beta participation interest was high (mean 8.45/10; 22/29 [76%] rated ≥8). Conclusions: Workshop alumni prioritized tools supporting surveillance tracking, visit preparation, peer support, and research engagement. These findings inform Precision Insight’s initial build and demonstrate feasibility for patient-partnered beta testing; broader validation in more diverse Lynch syndrome populations is warranted.

Dashes indicate that a corresponding feature value rating was not collected for that specific task category in the survey.
