## About Dataset

The GHW Heart Failure Readmission Prediction Dataset is real-world General Hospital Wards (GHWs) data. It is based on 30-days and 60-days hospital readmission prediction for heart failure patients. This dataset includes patient demographics, hospitalization history, vital signs, laboratory tests, and heart failure-specific features.
