The control group received usual treatment andcare.Main outcome measures Primary outcome measure was agitation(scores on Cohen-Mansfield agitation inventory). Secondary outcomemeasures were aggression (scores on neuropsychiatric inventory-nursinghome version), pain (scores onmobilisation-observation-behaviour-intensity-dementia-2), activities ofdaily living, and cognition (mini-mental state examination).Results Agitation was significantly reduced in the intervention groupcompared with control group after eight weeks (repeated measuresanalysis of covariance adjusting for baseline score, P<0.001): theaverage reduction in scores for agitation was 17% (treatment effectestimate −7.0, 95% confidence interval −3.7 to −10.3). Treatment of painwas also significantly beneficial for the overall severity of neuropsychiatricsymptoms (−9.0, −5.5 to −12.6) and pain (−1.3, −0.8 to −1.7), but thegroups did not differ significantly for activities of daily living or cognition.

Delirium • Synonyms: acute confusional state, organic brain syndrome, encephalopathy, terminal agitation, terminal restlessness • Often mistaken for depression, anxiety, or dementiaTerminal Agitation:A symptom or sign: thrashing, agitation that may occur in the last daysor hours of life.May be caused by: • pain • anxiety • dyspnea • delirium

  • 29. General Assessment: Delirium• Hospice diagnosis, co-morbidities• Onset of mental status change• Oral intake, urine output, bowel movements• Recent medication history• Review of systems: fever, N/V, pain, dyspnea, cough, edema, dec ubiti• Alcohol or illicit drug use• Falls, safety• Emotional, spiritual distress
  • 30. Assessment: Paul• Metastatic non-small cell lung cancer• Severe Alzheimer’s disease• More restless, combative in last 3 days• Hand-fed small, pureed meals & thickened liquids but minimal in 3 days• Small amount dark urine, no BM in 1 week
  • 31. Assessment Tools: Delirium• Confusion Assessment Method (CAM) – 94-100% sensitive, 90-95% specific – 10-15 minutes by trained interviewer• SQiD (single question in delirium) – “Do you think Paul has been more confused lately?” – 80% sensitive and 71% specific in oncology patient
  • 32. Confusion Assessment MethodFeature 1: Acute Onset Obtained from a family member or nurse:and Fluctuating Course • Is there evidence of an acute change in mental status from the patient’s baseline? • Did the (abnormal) behavior fluctuate during the day, that is, tend to come and go, or increase and decrease in severity?Feature 2: Inattention • Did the patient have difficulty focusing attention, for example, being easily distractible, or having difficulty keeping track of what was being said?Feature 3: • Was the patient’s thinking disorganized or incoherent, suchDisorganized thinking as rambling or irrelevant conversation, unclear or illogical flow of ideas, or unpredictable switching from subject to subject?Feature 4: Altered • Overall, how would you rate this patient’s level ofLevel of consciousness consciousness? alert [normal]), vigilant [hyperalert], lethargic [drowsy, easily aroused], stupor [difficult to arouse], or coma [unarousable])The diagnosis of delirium by CAM requires the presence of features 1 and 2 and either 3 or 4.
  • 33. Diagnostic Approach to Delirium• Delirium is a clinical, bedside diagnosis• Careful, gentle approach to patient• Appearance, vital signs• Focused exam based on history• Consider rectal exam, catheter
  • 34. Paul’s assessment: Delirium• Lethargic, frail, elderly man lying in hospital bed; fidgeting of arms, legs; slow but persistent attempts to sit up or slide between side rails; quiet but anxious expression• CAM: all features present• Afebrile, BP 105/62, HR 95, RR 24• Positive findings: – MM dry; – Foley catheter w/cloudy, dark urine; – abd distended but soft, – quiet BS; rectal +stool; – decubitus stable w/o infection
  • 35. Next steps: managing deliriumweighing benefits & burdens• Lab tests• Treating underlying cause(s)• Treating agitation
  • 36. Paul’s follow up Goals of care: Peaceful death at home • DNH • no needlesticks Treated the treatable Treated the delirium • Disimpaction, daily bowel • Haloperidol 0.5-1mg SL qHS regimen and q8hrs prn • Treated UTI w/ liquid • Calmer environment antibiotics • Improved communication • Weaned lorazepam • Encouraged safe movementIn 2-3 days, Paul was back to baseline
