ADHERE Tree Model: Explanation and Clinical Context The ADHERE Tree Model is a validated bedside tool to estimate in-hospital mortality risk for patients admitted with acute decompensated heart failure (ADHF). It uses three key clinical variables readily available at hospital admission: Blood Urea Nitrogen (BUN), Systolic Blood Pressure (SBP), and Serum Creatinine. Based on these values, patients are stratified into low, intermediate, or high risk categories, with corresponding estimated in-hospital mortality rates. This simple decision-tree approach allows rapid bedside risk assessment and aids clinicians in identifying patients who may require more intensive monitoring or intervention.
