Improving the Model for End‐Stage Liver Disease with sodium by incorporating kidney dysfunction types

Background and Aims We investigated the impact of the inclusion of kidney dysfunction type on the discrimination and calibration of the Model for End‐Stage Liver Disease with sodium (MELD‐Na‐KT) score. Approach and Results We included all adults listed for ≥90 days without exception points from January 1, 2008, through December 31, 2018. We defined kidney dysfunction types as follows: acute kidney disease (AKD; an increase of ≥0.3 mg/dL or ≥50% in serum creatinine in the last 7 days or fewer than 72 days of hemodialysis), chronic kidney disease (CKD; an estimated glomerular filtration rate
