- Abstract
- PURPOSE: Shared decision-making manages genomic uncertainty by integrating molecular and clinical uncertainties with patient values to craft a person-centered management plan. Laboratories seek genomic report consistency, agnostic to clinical context. Molecular reports often mask laboratory-managed uncertainties from clinical decision-making. Better integration of these uncertainty management strategies requires a nuanced understanding of patients' perceptions and reactions to test uncertainties. We explored patients' tolerance of variant uncertainty in three parameters: 1. Relative causal significance, 2. Risk Accuracy, and 3. Classification validity. METHOD: Deliberative forum were undertaken with 18 patients with predictive testing experience. Uncertainty deliberations were elicited for each parameter. A thematic framework was first developed and mapped to whether they justified tolerance for more or less parameter-specific uncertainty. RESULTS: Six identified themes mapped to clinical and personal domains. These domains generated apposing forces when calibrating uncertainty. Personal themes justified tolerance of higher uncertainty, and clinical themes lower uncertainty. Decision-making in uncertainty focused on reducing management regret. Open communication increased tolerance of Classification Validity and Risk Accuracy Uncertainty. Using these data, we have developed a nascent clinical algorithm integrating molecular uncertainty with clinical context through a targeted communication framework. CONCLUSION: Maximizing test utility necessitates context-specific recalibration of uncertainty management and communication.
