Development and internal validation of an ICU mortality prediction model for patients with concurrent sepsis and heart failure: a retrospective cohort study based on eICU-CRD.

This study developed and internally validated a predictive nomogram based on eight routine clinical variables for ICU mortality in patients coded for both sepsis and heart failure.

The model demonstrated acceptable discrimination and calibration.

However, given the broad, code-based case definition and the lack of heart failure-specific variables, this tool should be reframed as an internally validated ICU mortality prediction model for this high-risk population, rather than as a cardiology-specific or clinically actionable nomogram.
