Cut-off values of the RISE UP score and prognostic accuracy for mortality or ICU admission
| Cut-off value (%) | Patients (n%) * | Deaths or admissions to ICU (n%) † | Sensitivity (%, 95% CI) | Specificity (%, 95% CI) | PPV (%, 95% CI) | NPV (%, 95% CI) |
| <5 | 41 (6.6) | 3 (7.3) | 98.6 (96.1 to 99.7) | 9.5 (6.8 to 12.7) | 37.2 (36.4 to 38.1) | 92.7 (79.8 to 97.6) |
| <10 | 121 (19.5) | 6 (5.0) | 97.3 (94.1 to 99.0) | 28.6 (24.2 to 33.3) | 42.6 (41.0 to 44.2) | 95.0 (89.6 to 97.7) |
| >30 | 221 (35.6) | 145 (65.6) | 59.2 (52.7 to 65.4) | 79.8 (75.4 to 83.7) | 65.6 (60.3 to 70.5) | 75.0 (71.9 to 77.9) |
| >50 | 74 (11.9) | 46 (62.1) | 20.5 (15.4 to 26.4) | 93.0 (90.0 to 95.3) | 62.2 (51.4 to 71.8) | 67.5 (65.9 to 69.0) |
*The total number of patients described in this table is 621, because of missing the RISE UP scores in 21 patients.
†The percentages of deaths or ICU admissions are related to the amount of patients above or below that cut-off value.
ICU, intensive care unit; n, number of cases; NPV, negative predictive value; PPV, positive predictive value; RISE UP, Risk Stratification in the Emergency Department in Acutely ill Older Patients.
