Factor Associated with Readmission | Crude Odds Ratio | 95% Confidence Interval | Multivariable Adjusted* Odds Ratio | 95% Confidence Interval |
---|---|---|---|---|
Prior Coronary Intervention | 2.09 | 1.38, 3.16 | 2.05 | 1.34, 3.16 |
Prior Chronic Kidney Disease | 2.36 | 1.47, 3.79 | 1.89 | 1.15, 3.10 |
Minimum Serum Sodium** | 0.90 | 0.86, 0.95 | 0.91 | 0.86, 0.97 |
Current Smoking | 0.31 | 0.11, 0.87 | 0.25 | 0.09, 0.72 |
Low Health Literacy | 1.83 | 1.21, 2.75 | 1.75 | 1.14, 2.69 |
From the enhanced model adjusting for all factors associated with readmission with a p <0.1.
Each 1 mEg/L higher in minimum serum sodium (mEq/L) was associated with a 9% lower adjusted odds of 30-day readmission.
