Scientific title
Study objectives1. The duration of delirium in people aged 65 or over on admission to an acute medical care of the elderly ward, or with onset at any time 3 weeks after admission, will be significantly less when treated with rivastigmine up to 3 mg daily compared to placebo, whether or not supplemented by risperidone 1 mg in divided doses daily
2. The proportion of older people who develop a delirium postoperatively following an orthopaedic procedure will be significantly less when treated with rivastigmine up to 3 mg daily compared to placebo, whether or not supplemented by risperidone 1 mg in divided doses daily
3. The percentage of patients who experience adverse events or complications on rivastigmine compared to placebo will be significantly less than those receiving treatment as usual
4. The percentage of patients who relapse after three delirium-free days after an episode of delirium will be significantly higher in those previously treated as usual than those treated with rivastigmine
5. These differences will remain significant irrespective of pre-admission cognitive function
