Guidelines for risk reduction and management of delirium were published in March 2019 by the Scottish Intercollegiate Guidelines Network.[1]
Detecting Delirium
Use the 4 As Test (Arousal, Attention, Abbreviated Mental Test 4 [AMT4], Acute change) for identifying patients with probable delirium in emergency and acute hospital settings. This tool may also be used in community or other settings.
In the ICU setting, use the Confusion Assessment Method for the ICU (CAM-ICU) or the Intensive Care Delirium Screening Checklist (ICDSC) to identify patients with probable delirium.
Use CT brain scan in those patients presenting with delirium in the presence of the following:
New focal neurological signs
Reduced level of consciousness
A history of falls
Head injury
Anticoagulation therapy
Consider an electroencephalogram when there is suspicion of epileptic activity or non-convulsive status epilepticus.
Reducing Risk of Delirium
Consider all of the following as part of a package of care for patients at risk for delirium:
Ensuring patients have their glasses and hearing aids, if applicable
Promoting sleep hygiene
Early mobilization
Pain control
Prevention, early identification, and treatment of post-operative complications
Maintaining optimal hydration and nutrition
Regulation of bladder and bowel function
Provision of supplementary oxygen, if appropriate
Monitor depth of anesthesia in patients 60 years of age and older undergoing surgery that is expected to last more than 1 hr.
Treating Delirium
Consider acute, life-threatening causes of delirium. These may include low oxygen level, low blood pressure, low glucose level, and drug intoxication or withdrawal.
Identify and treat potential causes such as medications and acute illness. Multiple causes are common.
Optimize physiology, environment, and medications to promote brain recovery.
Detect and treat agitation or distress with non-pharmacologic means, if possible.
Communicate diagnosis to patients and caregivers and provide ongoing support.
Attempt to prevent delirium complications such as immobility, falls, pressure sores, dehydration, malnourishment, and isolation.
Monitor patient recovery and refer to a specialist if necessary.
