Clinical Risk-Weighted Evaluation of ICU Mortality Prediction Models on MIMIC-IV

2026-07-29

Abstract excerpt

<title>Abstract</title> <p>In ICU mortality prediction, a False Negative (FN) error—a missed death—carries a graver clinical consequence than a False Positive (FP) false alarm. However, models are routinely evaluated using the F1 score, which penalises FN and FP equally. We propose the Clinical Risk-Weighted Score (CRWS), a twoparameter generalisation of the F-β score that decouples FN and FP penalty weights for...
