Key result
AI using heart rate complexity and hemodynamics matches or outperforms SAPS-2 for predicting ICU mortality.
Why the study?
Commonly used ICU mortality prediction tools such as SAPS-2 rely heavily on comprehensive clinical data and blood samples, prompting the development of models using key hemodynamic parameters.
Does an AI model utilizing hemodynamic parameters improve mortality prediction compared to SAPS-2 in ICU patients?
Cohort (n=1,888)
Does an AI model utilizing hemodynamic parameters improve mortality prediction compared to SAPS-2 in ICU patients?
An AI model using basic clinical and hemodynamic parameters, including heart rate complexity, provides comparable or superior ICU mortality prediction compared to the SAPS-2 score without requiring extensive laboratory data.
May aid simpler ICU mortality prediction; hypothesis-generating and requires prospective validation before adoption.

Boussen et al. (2024) conducted a cohort in ICU patients (n=1,888). Artificial intelligence model vs. Simplified Acute Physiology Score II (SAPS-2) was evaluated on ICU mortality. An artificial intelligence model utilizing heart rate complexity and hemodynamic parameters predicted ICU mortality (overall rate 24.0%) with performance comparable or superior to SAPS-2.
