Rivastigmine in the Management of Delirium (confuriv)
A Randomized, Double-blind, Placebo-controlled Study of an Acetylcholinesterase Inhibitor in the Management of Delirium in Hospitalized Patients Aged 75 Years and Over
The aim of this study is to evaluate the efficacy of an anticholinesterase treatment in patients aged 75 and over, hospitalized with delirium.
Study type : Interventional Study design: randomized, double-blind, placebo-controlled study during one month and a 11-month follow-up

Detailed Description
Delirium affects up to 50% of hospitalized patients aged 75 and over. Delirium increases risk of comorbid illness, hospital length of stay, institutionalization, and death. Patients with diagnosed or undiagnosed cognitive impairment are at risk to develop delirium. In a prospective study, half of elderly patients with delirium seen in the emergency department had cognitive impairment.
Hypothesis: cholinesterase inhibitors reduce duration and severity of delirium
Main objective:
- to assess the efficacy of cholinesterase inhibitors in patients aged 75 and over hospitalized with delirium
Secondary objectives:
- to describe at one year the percentage of these patients who have a diagnosis of Alzheimer's disease and associated disorders
- to assess the sensitivity to cholinesterase inhibitors in the sub-group of patients with a diagnosis of dementia at one year Design and methods Multicenter, randomized, controlled study with two parallel arms: a rivastigmine group and a placebo group. The study includes a treatment period of one month and a follow-up of 11 months.
Evaluation of the delirium severity will be conducted with DRS-R98 severity each day during the hospitalization.
At day 14, according to DRS-R98 severity score, interruption of treatment or upward dose titration At day 30, last treatment (active or placebo) administration and evaluation with CAM, DRS-R98 severity, MMSE and DSM IV dementia criteria. In case of dementia diagnosis, investigator (MD) will identify the etiologic diagnosis.
At month 3 and 12, evaluation with CAM, DRS-R98 severity, MMSE and DSM IV dementia criteria, number of consultation and hospitalization. In case of dementia diagnosis, , investigator (MD) will identify the etiologic diagnosis.

One transdermal patch of placebo per day from randomization to day 14 Before day 14: end of treatment if DRS R-98 severity < 10 during 2 consecutive days, At day 14 if DRS R-98 severity ≥ 10: One transdermal patch of placebo per day from day 14 to day 30 if DRS R-98 severity < 10, the placebo treatment will be stopped
