Key findings
• Charlson Comorbidity Index (CCI), red blood cell count (RBC), red cell distribution width (RDW), and age were the main factors influencing the 90-day readmission of patients with heart failure (HF). RBC and RDW were linearly correlated with the 90-day readmission of patients with HF, while CCI and age were nonlinearly correlated with the 90-day readmission of patients with HF.
What is known, and what is new?
• It is known that CCI, RBC, RDW, and age were the factors influencing the prognosis of patients with HF.
• This study revealed that RBC and RDW were linearly correlated with the 90-day readmission of patients with HF, while CCI and age were nonlinearly correlated with the 90-day readmission of patients with HF.
What is the implication, and what should change now?
• For patients with HF, clinicians should pay attention to patients’ CCI, RBC, RDW, and age.
