Why the study?
To evaluate how ICU illness severity scoring systems perform across settings and over time, and to determine when recalibration is sufficient versus when new models are needed.

Review
Key result
Regular recalibration with periodic rebuilding is generally required for most ICU illness severity scores and prediction models to maintain performance over time and across settings.

ICU scores need local performance checks before use; leaves open optimal recalibration thresholds versus new model development.
Regular recalibration with periodic rebuilding is required for ICU illness severity scores to maintain performance over time and across settings.
Barlow et al. (2026) conducted a review in Intensive care unit illness severity. ICU illness severity scoring systems was evaluated. Regular recalibration with periodic rebuilding is generally required for most ICU illness severity scores and prediction models to maintain performance over time and across settings.
