30-day readmission
readmission
In total, 128 patients (20.8%) in the intervention group and 119 (20.2%) in the control group were readmitted within 30 days after discharge from index admission. No difference in the risk of readmissions was found between the groups in the adjusted analysis (RR: 1.00; 95% CI: 0.80, 1.26; The sub-group analysis showed a statistically significant difference between the intervention and control groups when looking at the sodium and potassium levels. Patients with abnormal sodium and potassium levels in the intervention group had a lower risk of readmission than patients with abnormal sodium and potassium levels in the control group (RR: 0.60, 95% CI: 0.37, 0.98, and RR: 0.59, 95% CI: 0.35, 1.00, respectively).
