arXiv:2606.17450v1 Announce Type: new Abstract: Traditional comorbidity scores (e.g., Charlson and Elixhauser) are widely used for risk adjustment and patient stratification, but they have two key limitations: (i) they are largely mortality-centric and do not align well with other clinical outcomes, and (ii) their linear, rule-based structure cannot capture nonlinear, outcome-specific risk relationships. We propose a Machine-Learned Comorbidity Index (MLCI) that maps diagnosis codes to a single scalar by maximizing the normalized Hilbert-Schmidt Independence Criterion (nHSIC) between the learn
The proliferation of advanced machine learning techniques and increased access to large medical datasets are enabling more sophisticated predictive models in healthcare.
This development represents a significant step towards more accurate, personalized, and outcome-aligned risk assessment in clinical settings, moving beyond traditional, less granular methods.
Clinical risk adjustment and patient stratification can become more precise and outcome-specific, potentially leading to more effective treatment paths and resource allocation.
