Table 5. Calibration across seven different ICU types.
ICU Type | Actual Deaths | Predicted Deaths | SMR | Actual Readmits | Predicted Readmits | A:P Ratio |
Cardiac Medical | 425 | 430.1 | 0.99 | 1,214 | 1,195.0 | 1.02 |
Cardiovascular or Cardiothoracic Surgery | 209 | 193.9 | 1.08 | 613 | 599.0 | 1.02 |
Medical | 226 | 222.7 | 1.01 | 550 | 491.7 | 1.12 |
Mixed Medical-Surgical | 1,023 | 1,117.0 | 0.92 | 2,762 | 2,883.2 | 0.96 |
Neurological | 108 | 81.8 | 1.32 | 250 | 248.3 | 1.01 |

Trauma a | 3 | 1.78 | – | 15 | 10.7 | – |
Too few patients to reliably calculate.
SMR = standardized mortality ratio; A:P = actual to predicted.
