1. Delirium in the older person
Delirium is a sudden, fluctuating change in mental state, which disturbs thinking and attention, and results in changed behaviour.
If delirium is not recognized, it can lead to permanent disability or death.
This information is for anyone who supports an elder who develops a delirium – family members and health care professionals alike.
Island Health has produced two educational DVDs:
- Delirium in the Older Person: A Medical Emergency
A teaching DVD for health care staff
Delirium in the Older Person: Family Guide
A useful resource to help families recognize delirium and quickly seek medical attention
A Medical Emergency
Delirium is a change in mental state which comes on suddenly, fluctuates over 24 hours, alters consciousness, disturbs thinking and attention and results in changed behaviour. Symptoms include problems with attention, thinking, memory, psychomotor changes and disruption of the sleep-wake cycle (Lipowski, 1989; Ignatavicious, 1999; Bater, 2006; DSM-5, 2013).
Delirium is considered a “medical emergency”
Delirium affects older persons in all areas of health care. All staff must be skillful in recognizing and responding to it.
The statistics are shocking. Despite the fact that Delirium is treatable,
In Acute Care:
50% of older persons may develop delirium in hospital
40-50% of older persons develop delirium after hip surgery
70% of person 65+ admitted to intensive care (National Guidelines, 2014)
In Residential Care:
- 22-89% of residents with dementia experience delirium (National Guidelines, 2014)
2. Delirium in the Older Person: A Family Guide
Winner of a 2007 Gold Questar International Award for Video Communication.
This DVD is for families affected by delirium, to help them learn more about what it is and how to cope with it.
The 27-minute video follows the experience of two families when a loved one develops delirium. It includes information and advice from health care professionals and medical experts. A family's ability to recognize delirium can be of life-saving importance. Getting prompt assessment and treatment for the underlying cause can mean the difference between returning to normal life or being confined to increasing levels of care, or even death.
