The clinical presentation of cognitive disorders and delirium is associated with a high level of distress in patients, family members, and health care personnel.[1,2] Delirium is associated with a high burden of symptom distress, particularly in relation to delusions, perceptual disturbances, and psychomotor agitation. Incontinence, falls, failure to maintain adequate hydration, a prolonged hospital stay, and death are more likely to occur in the patient with delirium.[3-9] Dysfunctional cognition in the delirious patient hinders communication between patient and family and between patient and health care personnel. As a result, reliable symptom assessment, counseling, and active patient participation in the therapeutic decision-making process are all compromised.[10] Psychomotor agitation and emotional lability in the delirious patient may be misinterpreted as a presentation of increased pain expression.[11] Consequently, conflict can arise among the patient, family, and staff concerning the level of analgesia needed. A potentially destructive triangle can develop when the patient’s family misinterprets agitation as increased pain and advocates for inappropriate escalation of opioid dosing.[12] A psychosocial intervention for family caregivers of patients with advanced cancer may be beneficial in providing knowledge of delirium and detection rates and in increasing family caregiver self-confidence in decision making.[13]
