Accuracy of the Delirium Observational Screening Scale (DOS) as a screening tool for delirium in patients with advanced cancer

Table 4 DRS scores in DOS positive patients

DOS score	N=	DRS-R-98 total score median	DRS-R-98 total score IQR
3-4^a	50	22.3	19.0–24.1
> 4-6^b	23	23.5	21.5–26.0
>6^c	20	26.0	21.8–27.4

Distribution of the DRS-R-98 scores in patients screened positive for delirium with the DOS. When comparing the absolute DOS score to the DRS-R-98 total score a linear association was found; B 0.677, 95% CI .229–1.126, P0.004
^a1st and 2nd quartile
^b3rd quartile
^c4th quartile
