Table 7.
Detection efficacy of RADAR (3–4 RADAR administrations)
| Number of daily CAM assessments | Time required (min) | Sensitivity | Specificity | Relative detection efficacy a) |
|---|---|---|---|---|
| 3 CAM + 1 HDS | 30 + 20 = 50 | 100% (23/23) | 95% (162/170) | 1 |
| 2 CAM + 1 HDS | 20 + 20 = 40 | 91% (21/23) | 98% (167/170) | 1.14 |
| 1 CAM + 1 HDS | 10 + 20 = 30 | 78% (18/23) | 98% (167/170) | 1.30 |
| RADAR | 4 * 7 sec. = 0.5 | 73% (8/11) | 67% (68/102) | 73 |
CAM: Confusion Assessment Method; HDS: Hierarchic Dementia Scale.
a)The relative detection efficacy compares the number of successfully detected cases per minute using various assessments to our gold standard of 3 CAM interviews and one HDS.
