Prevalence of cognitive impairment in the hospitalized elderly.
Surveys of older populations reveal rates of senile dementia varying from 5.2% to 25%. The specialist branch of psychiatry dealing with the elderly advocates that services for these patients and their carers should predominantly be based outside hospital.

In the acute hospital 112 patients with an average age of 74.7 years were examined and 22.3% of these had significant cognitive impairment.
These patients were predominantly sited on medical wards.
On acute medical wards 31% of older patients had significant impairment compared to only 7.3% on the surgical wards.
