Thirty-Day Readmission Risk Scores for the Model at Admission
| Risk Factor | β-Coefficient | Pointsa |
|---|---|---|
| Any admissions in previous 6 mo | .53 | 1 |
| Any ED visits in previous 6 mo | .71 | 2 |
| No. CCC categories | ||
| 1 | Reference | 0 |

Points calculated by multiplying β-coefficients by 2.5 and rounding to the nearest integer; this allowed 1 or more variables to have a point value of 1, generating a more continuous distribution of risk scores, and differentiated between levels of the categorical variable. Points added to compute a readmission risk score.
