Conformal selective prediction with cost aware deferral for safe clinical triage under distribution shift
This paper introduces a robust selective prediction framework for clinical triage, integrating calibrated probabilistic modeling, conformal prediction, and cost-aware deferral. Designed for safety-critical applications like early sepsis detection, it ensures reliable uncertainty quantification and prioritizes patient safety by deferring low-confidence cases to human experts, even under distribution shifts.
Key Executive Impact & ROI

Strategic Deferral for Enhanced Patient Outcomes
Discover how optimizing for clinical costs can lead to safer AI decisions, especially in high-stakes environments like early sepsis detection.
Prioritizing Patient Safety with Cost-Aware Deferral
The framework optimizes a single deferral threshold (τ*) by minimizing an explicit expected clinical cost on a held-out calibration set. This cost model reflects real-world clinical priorities, where the cost of a false negative (e.g., missed sepsis) far outweighs a false positive or a deferral. This approach ensures that the system aligns with safety-first objectives, making predictions only when sufficiently confident and deferring uncertain cases to clinicians.
Key Takeaway: By embedding clinical cost preferences directly into the deferral policy, the system ensures patient safety is prioritized, leading to more trustworthy and deployable AI in healthcare.
