Introduction
A confusional state. (from the Latin de-lira 'off the path')
Also see hypoactive delirium.
Etiology
D - drugs*, dehydration
E - electrolyte imbalances*, environment, endocrine*
L - liver disease (encephalopathy), lungs (hypoxia)
I - infection*, immune dysfunction, intracranial lesions, immobility
R - retention, restraint
I - ischemia*, intoxication, intestinal obstruction
U - uremia
M - myocardial disease*, metabolic abnormalities
- Drugs & toxins: (see drugs commonly producing delirium)
- Endocrine:
- Electrolytes:
- Infection:
- especially urinary tract infection* & pneumonia
- Ischemia:
- Retention (urinary retention or fecal impactation {constipation})
- Restraints & other tethers: IV lines, catheters, ECG leads
- Cardiovascular disease:
- Metabolic abnormalities:
- consider withdrawal syndromes
- uncontrolled pain, cancer pain[90][96]
- sensory deprivation: hearing impairment, visual impairment[3]
- sleep deprivation[3]
- surgery
* no association between asymptomatic bacteriuria & delirium[81]

drugs commonly producing delirium
Epidemiology
- 20-50% of hospitalized elderly patients
- most common contributor to excess length of hospitalization[5]
- 75-90% of hospitalized patients with dementia[6]
- common in the intensive care unit[23]
- 3/4 of patients admitted to the ICU with respiratory failure, cardiogenic shock, or septic shock experience delirium during their hospital stay[24]
- often unrecognized
- fluctuating symptoms
- often attributed to dementia or psychiatric disorder
- baseline assessment facilitates recognition
- may persist for months without correction of underlying cause
Pathology
- relative cholinergic deficiency & dopaminergic excess
- glucocorticoids may play a role
- cognitive impairment, dehydration, hypoxia, infection, immobility, pain, poor nutrition, medication overuse,visual impairment, hearing impairment, & sleep deprivation contribute[18]
Clinical manifestations
- rapid onset* (develops over hours to days)[6]
- fluctuating with nocturnal exacerbation*
- 'sundowning'
- alteration in the sleep-wake cycle
- inattention* (distinguishing feature of delirium)
- impaired concentration
- reduced level of consciousness# (inappropriately falls asleep)
- impaired cognition#
- disorganized thinking
- learning & memory impairment (recent & remote)
- perceptual disturbances
- hallucinations, visual > auditory
- psychosis & agitation
- impaired orientation
- disorders of affect
- personality changes
- often incoherent speech; dysarthria may contribute
- unpredictable psychomotor activity
- asterixis, coarse tremor or myoclonus
- underlying disease or drug toxicity
- autonomic dysfunction
- tachycardia or bradycardia
- hypertension or hypotension
- flushing or pallor
- impairment of pupillary function
- abnormal control of sweating
- delirium may persist more that 6 months[3][7][8][9]
- confusion assessment method (CAM) is the best beside measure[16]
- reciting months of the year backward has better sensitivity than confusion assessment method[36]
- 3D-CAM based is a 3 minute version of CAM[37]
* essential for diagnosis
# either confirms diagnosis[3]
Laboratory
- screening tests
- chemistries:
- hematology:
- complete blood count (CBC) & differential
- coagulation studies, PT, PTT
- arterial blood gas (ABG)
- serum CRP or ESR
- urinalysis & urine toxicology screen
- blood alcohol
- toxicology for ingested drugs
- therapeutic drug monitoring as indicated
- HIV testing
- additional testing as indicated
Diagnostic procedures
- electrocardiogram (EKG)
- electroencephalogram
- generally, slowing or low-voltage activity
- generalized EEG slowing in patients with altered mental status[73]
- triphasic waves may suggest hepatic disease
- periodic lateralizing epileptiform discharges suggest CNS infection
- 24 EEG monitor for non-convulsive status epilepticus
- fluctuating mental status of unknown origin[3]
- repeated episodes of staring, lethargy. nonresponsiveness
- fluctuating mental status of unknown origin[3]
- generally, slowing or low-voltage activity
- see Clinical manifestations: (above) for confusion assessment method (CAM)
Radiology
- chest X-ray
- neuroimaging as indicated, CT neuroimaging, MRI neuroimaging
- diagnostic yield of head CT in delirium (emergency department or inpatient) is 13%
- presence of focal neurologic deficit increases yield to 19%
- yield higher in neurological ICUs (40%)
- reserve for patients with falls associated with head injury or focal neurologic signs[3]
- diagnostic yield of head CT in delirium (emergency department or inpatient) is 13%
Complications
- increased length of hospital stay[10]
- increased mortality[11][17][40][95] (RR=1.71-2.19)
- increased time spent on the ventilator, leading to increased incidence of ventilator associated pneumonia
- increased rate of subsequent institutionalization (HR=2.41)[17]
- delirium accelerates cognitive decline in patients with Alzheimer's disease
- increased rate of cognitive decline for up to 5 years[34]
- this seems in contrast to estimates of cognitive impairment due to postoperative delirium (see below)
- it also seems a second episode of delirium would likely nullify any 5 year estimate based on a single episode
- increased rate of cognitive decline for up to 5 years[34]
- 10-fold increased risk of cognitive impairment at hospital discharge (HR=12.5)[17]
- increased risk of dementia (HR=12.5)[95]
- prolonged cognitive impairment after postoperative delirium[20] (6-12 months)
- in ICU patients, a longer duration of delirium (5 days) independently predicts worse cognition at 3, 6 & 12 months, regardless of patient age or comorbidities [24, 40]
- delirium is an independent risk factor for long-term cognitive decline in surgical & nonsurgical patients[76]
- functional decline[5][54]
- decline in activities of daily living[56]
- increased mortality in ICU patients (RR=2.19)[40]
- independent predictor of poor long-term outcomes, including cognitive decline & functional decline, institutionalization, & death in the elderly
- cognitive decline & functional decline correlates with duration of delirium & persists at 6 months after hospital discharge[5][76]
- disease interaction(s) of delirium with pyuria & bacteriuria
- disease interaction(s) of delirium with urinary incontinence
- disease interaction(s) of delirium with Alzheimer's disease
Differential diagnosis
- dementia
- psychosis (see psychosis & agitation in the elderly)
- transient global amnesia
- aphasia
- visual hallucinations due to structural lesions in the occipital lobes or cerebral peduncles
- depression vs hypoactive delirium[5]
- sudden onset suggests cerebrovascular disease or seizure
- non-convulsive status epilepticus[63]
- suspect if fluctuating mental status of unknown origin[3]
- non-convulsive status epilepticus[63]
- encephalopathy
- also see dementia vs delirium vs depression
Management
general
- urgent evaluation & management indicated []
- general in hospital guidelines (NICE)[5]
- identify patients at risk for delirium
- establish a multidisciplinary team to prevent & manage delirium
- prevention is key[5]
- multicomponent nonpharmacological interventions are effective in reducing incidence of delirium & preventing falls in the elderly[42][92]
- once delirium occurs, multidisciplinary team of no benefit over standard care[5]
- avoid moving the patient between different rooms & wards
- ensure environment
- maintain hydration & avoid constipation
- vigilance for urinary retention
- avoid unnecessary use of urinary catheter
- antibiotics do not improve symptoms of delirium in elderly with pyuria or bacteriuria without systemic signs of infection or genitourinary symptoms[98]
- prevent & treat hypoxia & infections
- encourage mobility with appropriate assistance & supervision
- early exercise & mobility shortens duration of delirium, shortens hospital stay & improves physical function & 1 years survival (GRS9)[5]
- assess & manage pain & sensory impairment
- optimize pain control
- vision assistance (eyeglasses)
- hearing assistance (hearing aids)[3]
- review medications to determine whether any may increase risk of delirium
- promote & maintain nutrition & sleep hypgiene (allow uninterrupted sleep)
- frequent reorientation[3]
- correction of underlying precipitating factor(s)
- discontinue offending medications
- remove unnecessary catheters
- correct medication withdrawal syndromes (see Etiology:)
- may need to rule out non-convulsive status epilepticus[3]
- antidotes
- Narcan 0.1 mg/kg or 0.4-2.0 mg or more IV/IM/SC/ET
- consider flumazenil
- consider IV/IM thiamine if history of alcoholism, malnutrition, or chronic GI disorder associated with malabsorption, especially with nystagmus (ophthalmoplegia), & ataxia
- withdrawal of non-essential medications
- restraints may actually precipitate delirium
- supportive care
- close observation until delirium clears
- individualized management of delirium precipitants & supportive strategies result in shorter duration of distressing delirium symptoms in palliative care patients than when risperidone or haloperidol is administered[64]
Pharmacology
- pharmacologic agents
- indications:
- agitation not responding to non-pharmacologic measures
- hypoactive delirium
- no drug is FDA-approved for prevention or treatment of delirium[3]
- evidence does not support use of antipsychotics for prevention or treatment of delirium[65][66][72]
- antipsychotic use is not associated with change in delirium duration, severity, or hospital or ICU length of stay, high heterogeneity among 19 studies[82]
- use low dose high potency antipsychotic[5] (not useful)[65][66][72]
- avoid using in patients with Parkinson's disease or Lewy body dementia[35]
- may worsen cognition
- may result in neuroleptic malignant syndrome
- NEJM Knowledge+ suggests high potency antipsychotic treatment of choice in patients who fail nonpharmacololgic intervemtions[91]
- avoid using in patients with Parkinson's disease or Lewy body dementia[35]
- antipsychotics, conventional (not useful)[65][66][72]
- Haldol* 0.5-5 mg IV/IM/PO every 30-60 min
- Haldol increases the duration of delirium in the ICU, albeit less so than lorazepam[5][27]
- Haldol plus rivastigmine increases mortality in the ICU[32]
- prophylactic haloperidol does not improve survival in ICU patients at 28 days[68]
- neither haloperidol nor ziprasidone shortens duration of delirium in ICU patients[69]
- only combination of haloperidol + lorazepam better than placebo[70]
- better than haloperidol alone, rivastigmine, olanzapine, or dexmedetomidine
- haloperidol 1.0-3.8 mg QD for 3-11 days associated with very-small dose-dependent improvement in survival of critically-ill patients with delirium (RR=0.91-0.95 at 28 days, 0.96-0.98 at 90 days)[80]
- haloperidol no better than placebo for treatment of delirium in ICU patients[87]
- drug of choice in hospitalized elderly[5][21]
- atypical antipsychotics: (not useful)[65][66][72]
- may help control behavior when safety is a concern (MKSAP19)[3]
- limited evidence of true efficacy in treating delirium[33]
- use in controlling behavior rather than treating delirium[91]
- respiridone, quetiapine, olanzapine
- quetiapine preferred agent for patients with Parkinson's disease or Lewy body dementia[5][35]
- may be as effective as haloperidol[33]
- respiridone may be useful in surgical ICU[75]
- neither haloperidol nor ziprasidone shortens duration of delirium in ICU patients[69]
- all antipsychotics (atypical or conventional) associated with increased risk of mortality when used to treat psychosis, agitation & difficult behavior in the elderly
- compared with placebo, neither haloperidol nor ziprasidone decreases time that ICU patients remain alive without delirium or coma[14][69]
- neither haloperidol nor ziprasidone has significant effects on cognition, function, quality-of-life, or psychological outcomes in critically ill patients with delirium[101]
- benzodiazepines
- benzodiazepines should not be used to treat delirium in the absence of alcohol withdrawal, benzodiazepine withdrawal or seizures[3]
- lorazepam (Ativan) 0.5-1 mg every 1-2 hours IV/IM/PO
- benzodiazpines increase the duration of delirium in the ICU[5][27]
- coadministration of benzodiazepine with antipsychotic (haloperidol) may benefit elderly at end-of-life or with terminal cancer[3]
- opiates increase the duration of delirium inthe ICU[5][27]
- dexmedetomidine for up to 1 week may shorten duration of delirium & mechanical ventilation time in ICU patients[43]
- ramelteon 8 mg QHS
- reduces risk of delirium in hospitalized elderly (3% vs 32%) (small study 67 patients)[48]
- useful for prevention in medical ICU[75]
- may be useful for treatment of delirium (smaller study 10 patients)[49]
- discontinuation of previously used statin associated with increased risk of delirium[59]
- routine use of anticonvulsants for the prevention &/or treatment of delirium among older adults cannot be recommended[77]
- indications:
Prognosis
- delirium is an independent predictor of poor long-term outcomes, including cognitive decline, functional decline, institutionalization, & death
- often leads to poor outcomes
- persistent cognitive changes in > 20%[6]
- accelerates cognitive decline in patients with Alzheimer's disease[31]
- little is known about the relationship between delirium & cognitive trajectories in the elderly[31]
- increased risk of
- prolonged hospitalization
- loss of cognitive & functional abilities
- mortality (25-40% within 30 days)[6]
- increased risk persists for 1-2 months following in-hospital delirium
- delirium in the emergency department predicts high 6 month mortality[15]
- dementia worsens prognosis
- delirium is a marker of critical illness & increased vulnerability, not a cause of increased mortality[39]
- cognitive impairment during periods of delirium does not necessarily indicate dementia
- often leads to poor outcomes
- patient education after delirium clears
- avoidance of precipitating factors
- disease-specific information
Prevention
- prevention is key
- more difficult to treat delirium than to prevent it
- see prevention of delirium[97]
- target risk factors[5]
- cognitive impairment
- sleep deprivation
- immobility
- visual impairment (eyeglasses)
- orientation: calendar, clock, name of facility visible
- dehydration
- postoperative: keep hematocrit >= 30%
- maintaining blood hemoglobin > 10 g/dL unlikely to affect risk of delirium[55]
- dexmedetomidine may prevent postoperative delirium[61] but may not be beneficial after extubation
Guidelines
- guidelines for optimizing delirium care within an age-friendly health system with Hospital Elder Life Program (HELP) core interventions & the 4Ms[94]
Notes
in ICU patients,
- a longer duration of delirium (5 days) independently predicts worse cognition at 3 & 12 months,regardless of patient age or comorbidities
- at 12 months,
- 34% of patients with global cognition scores similar to scores seen in patients with moderate traumatic brain injury
- 24% with scores similar to those seen in mild Alzheimer's disease[24]
- at 12 months,
- a flexible family visitation policy, vs standard restricted visiting hours, does not significantly reduce the incidence of delirium[71]
