Path of Patient Readmitted: Path of Patient Readmitted:
  • If repaglinide is not administered to the patient, there is a 50% less chance of the patient being readmitted.
  • If the number of procedures (num_procedures) is below 1.5, there is a higher probability of patient readmission.
  • If the number of diagnoses (number_diagnoses) is 7.5 or lower, there is an increased likelihood of the patient being readmitted.
  • If the number of inpatient visits is more than 25%, there is a higher likelihood of the patient being readmitted.
  • If the number of inpatient visits exceeds 75%, there is a greater likelihood of the patient being readmitted.
  • For patients aged between 60-70, there is a 75% chance of them being readmitted.
Path of Not Readmitted: Path of Patient Not Readmitted:
  • If repaglinide is not administered to the patient, there is a 50% higher chance of the patient not being readmitted.
  • If the number of emergency cases (number_emergency) is 50% more, there is a greater likelihood of the patient not being readmitted.
  • If the number of outpatient visits exceeds 50%, there is a higher likelihood of the patient not being readmitted.
  • If the number of inpatient visits is less than 25%, there is a higher likelihood of the patient not being readmitted.
  • For patients aged between 30-40, there is a 75% lower chance of them not being readmitted.
  • For patients aged between 40-50, there is a 75% lower chance of them not being readmitted.
