Delirium: diagnosis, prevention and management [CG103]

Measuring the use of this guidance

Recommendation: 1.1.1

When people first present to hospital or long-term care, assess them for the following risk factors. If any of these risk factors is present, the person is at risk of delirium. • Age 65 years or older. • Cognitive impairment (past or present) and/or dementia. If cognitive impairment is suspected, confirm it using a standardised and validated cognitive impairment measure. • Current hip fracture. • Severe illness (a clinical condition that is deteriorating or is at risk of deterioration)

Recommendation: 1.2.1

At presentation, assess people at risk for recent (within hours or days) changes or fluctuations in behaviour. These may be reported by the person at risk, or a carer or relative. Be particularly vigilant for behaviour indicating hypoactive delirium (marked*). These behaviour changes may affect: • Cognitive function: for example, worsened concentration*, slow responses*, confusion. • Perception: for example, visual or auditory hallucinations. • Physical function: for example, reduced mobility*, reduced movement*, restlessness, agitation, changes in appetite*, sleep disturbance. • Social behaviour: for example, lack of cooperation with reasonable requests, withdrawal*, or alterations in communication, mood and/or attitude. If any of these behaviour changes are present, a healthcare professional who is trained and competent in diagnosing delirium should carry out a clinical assessment to confirm the diagnosis.

What was measured: Proportion of patients aged over 65 who were admitted to hospital for a non-elective reason and who had an assessment for the presence or absence of delirium or a documented diagnosis of delirium.
