| Annotation | The aim of this study was to provide an overview of prevalence, symptoms, risk factors and prognosis of delirium in primary care and institutionalised long-term care. The method used was a systematic PubMed search and literature review. Study results showed that the prevalence of delirium in the population among older adults aged 65 years and above is 1-2%. Prevalence rises with age: 10% among a `general' population aged 85 years and above. Prevalence rises up to 22% in populations with higher percentages of people with dementia. In long-term care, prevalence ranges between 1.4% and 70%, depending on diagnostic criteria and on the prevalence of dementia. There is a significant increase of the risk of delirium with age and cognitive decline in all groups. Concerning prognosis, most studies agree that older people who previously experienced delirium have a higher risk of dementia and a higher mortality rate. Population and long-term care studies show the same tendency. The study concludes that delirium in a non-selected population aged 65 years and above is uncommon. However prevalence rises very quickly in selected older groups. Primary care doctors should be aware of a relatively high risk of delirium among older people in long-term care, those older than 85 years and those with dementia. (JL) |
