At recognition, obtain vital signs, oxygenation assessment, bedside glucose, focused neurologic examination, medication administration history, pain assessment, intake-output review, and examination for urinary retention or constipation. Escalate immediately for focal neurologic findings, depressed consciousness, severe hypoxemia, shock, or other evidence of acute organ dysfunction; delirium may reflect systemic illness, metabolic disturbance, pharmacologic effects, trauma, or iatrogenic/environmental precipitants.

Do not label all postoperative agitation as delirium. Establish whether the course is acute and fluctuating with impaired attention; compare with the preoperative cognitive baseline through family, caregivers, or prior records. Preexisting dementia and functional, visual, hearing, or frailty-related impairment increase vulnerability, but do not explain an abrupt change without evaluating a superimposed precipitant.

Patients older than 60 years have reported postoperative delirium incidence of approximately 10% to 20%, while incidence varies substantially across surgical populations and ascertainment methods.

Use preoperative cognitive assessment and medication reconciliation to establish baseline and reduce avoidable exposure to medications that can precipitate delirium. Benzodiazepines can themselves precipitate delirium, but chronic benzodiazepines should not be abruptly discontinued preoperatively because discontinuation has also been associated with increased postoperative delirium risk.

Implement a multicomponent postoperative bundle: frequent orientation and cognitive stimulation, access to glasses and hearing aids, family presence when feasible, sleep protection, fluid and nutrition management, adequate analgesia, early mobilization, and daily delirium screening. These measures target modifiable environmental, sensory, immobility, sleep, and physiologic contributors.

Build the differential around common precipitant domains: surgical stress and complications, systemic illness or organ dysfunction, metabolic abnormalities, pharmacologic effects, iatrogenic or environmental factors, trauma, and withdrawal states.

Review the anesthetic, perioperative medication administration record, and home medications for sedative-hypnotics, anxiolytics, anticonvulsants, muscle relaxants, anticholinergic drugs, opioids, and dopaminergic agents. Medication burden can precipitate delirium; conversely, benzodiazepine withdrawal is a clinically important exception when chronic therapy has been interrupted.

Match tests to clinical evidence of a precipitant. Evaluate respiratory compromise when oxygenation or ventilation is abnormal; investigate infection or organ dysfunction when fever, hemodynamic change, localizing symptoms, or laboratory abnormalities are present; and assess urinary or bowel retention when examination or output history suggests obstruction. For new focal deficits or atypical depressed consciousness, urgently evaluate for structural neurologic disease. PubMedPubMedDifferentiating Delirium Versus Dementia in Older Adults - NCBI

Immediately protect the patient and staff while preserving assessment capacity. Use verbal de-escalation, reorientation, familiar environmental cues, sensory aids, family involvement, and mobilization when safe. Family presence supports behavioral management and reorientation, while multicomponent interventions can reduce symptom severity and duration.

Do not prescribe haloperidol or an atypical antipsychotic routinely to prevent or resolve delirium.

Do not use benzodiazepines routinely to prevent or treat postoperative delirium in older or critically ill adults.

Postoperative delirium is associated with adverse longer-term outcomes. In adults older than 60 years, reported 30-day mortality was 7% to 10% among patients with postoperative delirium versus 1% among those without delirium; these observational data support explicit discharge communication and follow-up planning rather than assuming cognition will normalize at discharge. PubMedPubMedDifferentiating Delirium Versus Dementia in Older Adults - NCBI

Before discharge, communicate the delirium episode, baseline cognition, suspected precipitants, medication changes, residual cognitive or functional deficits, and needed caregiver supervision. Because delirium is associated with institutionalization, morbidity, prolonged hospitalization, and mortality, disposition should account for the patient's ability to mobilize, maintain intake, and safely manage medications after surgery.
