Delirium subtype identification and the validation of the Delirium Rating Scale—Revised‐98 (Dutch version) in hospitalized elderly patients

Abstract

The results show that the Dutch version of the DRS-R-98 is a valid and reliable measure of delirium severity and distinguishes patients with delirium from patients with dementia and comparison patients. Furthermore, the DRS-R-98 is able to exclude hypoactive delirium.

A longitudinal study of motor subtypes in delirium: Relationship with other phenomenology, etiology, medication exposure and prognosis

“…In contrast, all cognitive and thought process abnormalities, and key diagnostic features were comparable across clinical subtypes. Therefore, our study using detailed assessment of a range of cognitive domains on the DRS-R98 and CTD, concurs with previous cross-sectional studies in elderly medical and consultation-liaison populations that found comparable cognitive and EEG abnormalities across motor subtypes of delirium [15,[35][36][37]. Overall, phenomenological studies suggest that cognitive and contextual items (i.e.…”

Serum S100B in elderly patients with and without delirium

“…(For subtyping, the delirium symptom interview was used, resulting in three different subtypes: hyperactive, hypoactive, and mixed (Liptzin and Levkoff, 1992). The Delirium Rating Scale-Revised-98 (DRS-R-98) was used to monitor the severity of delirium (Trzepacz et al, 1988;de Rooij et al, 2006).…”

Effect of melatonin on incidence of delirium among patients with hip fracture: a multicentre, double-blind randomized controlled trial

“…55,56 A trajectory of scores (i.e., to show a pattern of results over several days) would be most informative but proved infeasible because of the relatively short episodes of delirium. Therefore, we instead decided to use the total amount of haloperidol prescribed.…”
