Management of Delirium in Non-ICU Settings

Introduction to Delirium Management

The Society of Critical Care Medicine recommends against routine antipsychotic use, including haloperidol, for delirium treatment due to lack of benefit for delirium duration, mechanical ventilation time, ICU length of stay, or mortality, with high-quality evidence supporting this recommendation 1, 2, 3
The American Society of Critical Care Medicine explicitly states that antipsychotics should be reserved exclusively for patients with significant distress from hallucinations or delusions with fearfulness, agitation posing physical harm to themselves or others, and should be used for short-term periods only until distressing symptoms resolve 1, 2

Implement multicomponent interventions immediately before considering any medication, including early mobilization, sleep optimization, cognitive stimulation, and sensory optimization, as recommended by the Society of Critical Care Medicine 2, 3
Early mobilization is the single most effective intervention, getting patients out of bed and walking as soon as medically safe 3
Sleep optimization involves controlling light and noise, clustering care activities, and minimizing nighttime stimuli to protect sleep-wake cycles 3
Cognitive stimulation uses familiar objects, reorients frequently with calendars/clocks, and encourages family presence 3
Sensory optimization ensures glasses and hearing aids are in place and provides adequate daytime lighting 3

Antipsychotics should be used with caution and only when necessary, with atypical antipsychotics preferred over haloperidol due to lower rates of extrapyramidal side effects and potential to reduce delirium duration 2, 5
Risperidone is an effective alternative, with dosing at 0.5-4 mg daily, but should be avoided in patients with baseline QT prolongation, history of torsades de pointes, or concurrent QT-prolonging medications 4, 5
Benzodiazepines, rivastigmine, and diphenhydramine should be avoided due to worsening delirium, increased mortality, and anticholinergic burden 3, 4, 5

Discontinue antipsychotics as soon as acute distressing symptoms resolve to avoid unnecessary morbidity and financial cost 1, 2
Never use antipsychotics prophylactically to prevent delirium, as there is no evidence supporting this practice and it exposes patients to unnecessary harm 3, 4
Monitor patients on antipsychotics for oversedation, QT prolongation, extrapyramidal symptoms, and respiratory depression 5
