Delirium Defined

A transient global disorder of cognition; usually reversible cause of cerebral dysfunction; hallmarks are acute onset, decreased attention span, and waxing/waning confusion. High M&M medical emergency Early dx and tx outcomes Syndrome, not disease

In the elderly: Can lead to loss of independence 1-year mortality of 35 to 40% Accounts for > 49% of all hospital days Increases hospital costs by $2500/pt. $6.9 billion in Medicare Additl costs incurred: institutionalization, rehabilitation, home health care, informal caregiving 30-40% delirium cases preventable or iatrogenic

3 types delirium, based on arousal status Hyperactive: EtOH w/d, intoxication phencyclidine (PCP), amphetamine, lysergic acid diethylamide (LSD) Hypoactive: hepatic encephalopathy, hypercapnia Mixed: daytime sedation, nocturnal agitation & behavioral problems

Not elucidated; result of structural or physiologic insults Reversible impairment of cerebral oxidative metabolism & multiple NT abnormalities, i.e., ACh, DA, GABA, others Inflammatory mechanisms: IL-1, IL-6 in infection, inflammation, toxic insult, head trauma, ischemia Psychosocial stress & sleep deprivation Structural: lesions, disruption of BBB allows neurotoxins, inflammatory cytokines Hypoglycemia, hyperthermia, metabolic/electrolyte abnormalities, malnutrition Polypharmacy

14-56% of hospitalized elderly 10-22% of elderly on admission, 10-26% mortality 10-30% after admission, 22-76% mortality 40% ICU pts., 70-80% of elderly ICU pts. 5-10% post general surgery; 42% post orthopedic Up to 83% near death Up to 60% NCF patients More common in elderly Can present with existing dementiahx from family, staff, and chart review pertinent Sex and race indiscriminate

Clinical dx Detailed hx from family, caregivers, staff, records Acute or subacute deterioration in behavior, cognition, function Visual hallucinations, persecutory, or grandiose delusions May be homicidal or suicidal MMSE, CAM, Mini Cog, GDS Depression common Agitation, psychosis, abnormal behavior Develops within hours

Disturbance of sleep/wake cycle Daytime drowsiness Disorientation, illusions, hallucinations, altered consciousness Memory deficit, language disturbance Dysphagia, dysarthria, tremor, asterixis Hypervigilance or hypoactivity Fluctuating course, days to weeks, usually reversible Prodrome: hours to days; sleep disturbance, vivid dreams, frequent calls for assistance, anxiety

DSM-IV-TR diagnostic criteria Disturbance of consciousness (i.e., reduced clarity of awareness of the environment) occurs, with reduced ability to focus, sustain, or shift attention Change in cognition (e.g., memory deficit, disorientation, language disturbance, perceptual disturbance) occurs that is not better accounted for by a preexisting, established, or evolving dementia The disturbance develops over a short period (usually hours to days) and tends to fluctuate during the course of the day Evidence from the history, physical exam, or lab findings is present that indicates the disturbance is caused by a direct physiologic consequence of a general medical condition, an intoxicating substance, medication use, or more than one cause

Nearly any medical illness, intoxication, or medication; often multifactorial DSM-IV-TR classification General medical condition Substance intoxication Substance withdrawal Multiple etiologies Not otherwise specified (NOS)

Infectious CNS infections (meningitis) Encephalitis HIV-related brain infections Septicemia Pneumonia Urinary tract infections

Assessment: Altered mental status confusion & memory loss, possibly 2 to hypoxia, Abilify, UTI, or steroid-induced psychosis Pulmonary infiltrates, pneumonitis vs. pneumonia vs. recurrence of TB; most likely pneumonitis 2 to chemo UTI H/o breast CA HTN Hyperlipidemia Anxiety and depression Plan: Given Risperdal last night, mental status returned to normal overnight Pt. has contd O2 tx; breathing is improved F/u pulmonary, oncology, PCP 1-2 weeks Continue home Rx. Empiric Rocephin & Zosyn d to Cipro 250 mg po bid x 3 days. Prednisone taper for pneumonitis

Metabolic Fluid and electrolyte abnormalities, acid-base disturbances, hypoxia Hypoglycemia Hepatic or renal failure Vitamin deficiency, esp. thiamine & cyanocobalamin Thyroid/parathyroid endocrinopathies

Hypoperfusion states Shock CHF Cardiac arrhythmias Anemias

Structural changes Closed head injury or cerebral hemorrhage Cerebrovascular accidents Cerebral infarcts Subarachnoid hemorrhage Hypertensive encephalopathy Primary or metastatic brain tumors Brain abscess

Toxic Causes Substance intoxication: EtOH, heroin, MJ, PCP, LSD Substance withdrawal: EtOH, opiods, benzos Medication-induced: anticholinergics (Benadryl, TCAs) Narcotics (meperidine) Sedative hypnotics (benzos) H-2 blockers (cimetidine) Corticosteroids Centrally acting HTNsives (methyldopa, reserpine) Anti-Parkinson rx (levodopa)

Assessment: Altered mental status confusion & memory loss, possibly 2 to hypoxia, Abilify, or steroid-induced psychosis Pulmonary infiltrates, pneumonitis vs. pneumonia vs. recurrence of TB; most likely pneumonitis 2 to chemo UTI H/o breast CA HTN Hyperlipidemia Anxiety and depression Plan: Given Risperdal last night, mental status returned to normal overnight Pt. has contd O2 tx; breathing is improved F/u pulmonary, oncology, PCP 1-2 weeks Continue home Rx. Empiric Rocephin & Zosyn d to Cipro 250 mg po bid x 3 days. Prednisone taper for pneumonitis

Sensory deprivation, sleep deprivation, fecal impaction, urinary retention, change of environment Perioperative Meds at therapeutic doses Risk factors: physical restraints, malnutrition, bladder catheter, any iatrogenic event, Rx 3, dementia, dysmorphic mood, hopelessness

Medical Care Fluid & nutrition

Environmental

Manage electrolytes, volume resuscitation Multivitamins, esp. thiamine if suspicion of EtOH intoxication or w/d Reorientation (calendar, clock, photos) Stable, quiet, well-lit reassurance Vision & hearing correction Avoid physical restraints! Use sitters if necessary.

D/C any contributory, offending agents Reassessment Psychiatric Consult Consult other specialists as appropriate

Pharmacologic Tx Neuroleptics, MOC for psychotic symptoms; newer drugs have less extrapyramidal symptoms, neuroleptic malignant syndrome, tardive dyskinesia Haloperidol: high-potency; one of most effective; less sedating than phenothiazine Risperidone: improves negative symptoms of psychoses

Short-acting sedatives Reserved for seizures, w/d from EtOH, sedative hypnotics, ingestion of hallucinogen, cocaine, PCP, amphetamines Benzodiazepines preferred over neuroleptics CNS depressants Lorazepam: short-acting, IM or IV, no active metabolites

Vitamins Thiamine

Alcoholism, Wernickes, malnutrition

Cyanocobalamin (vit B12)Pernicious anemia, gastrectomy, distal ileum disease

Follow-up Recovery in elderly may be 6 weeks F/u with PCP, psychiatry, social workers, others involved in care

Early intervention: M/M, hospital stay, $$$ Monitor nutrition & hydration Minimize polypharmacy Substance abuse counseling Practice good sleep hygiene Correct visual & hearing defects Provide calm environment Social stimulation Physical exercise Educate pt. and family regarding disease etiology/course, risk factors, reorientation

Poor nutrient intake Decreased function and mobility Pressure ulcers from immobility Aspiration pneumonia Injury from falls and behavior Long-term impairment

Delirious by DSM-IV-TR criteria?A.

42 y/o AA Dean of Medicine of prominent university, POD #0 inpatient, s/p LTKA, rips out his IV and throws his lunch tray across the room. He violently insists that the food in this country club is awful, and wants his money back or else hes leaving! His nurse calls you into the room urgently to apprise you of the recent event. When you arrive, the patient is sitting up in bed, calmly observing the nurse reinsert his IV, and is inquiring about the IV rate of flow settings. 76 y/o widower, 2 days s/p emergent ligation of esophageal varices. Hospital stay has been benign until one hour ago when patient began rambling incoherently. During exam, he is generally uncooperative, but you are able to hold his attention long enough to ascertain the presence of nystagmus. 81 y/o W is in the step-down unit for seven days after leaving the ICU. On days 3-5, she was relatively sociable with the nurses, despite being bed bound. She slept most of day 6 and spent most of night 6 unnecessarily calling out to the nurses for help. Today, she is again quietly napping the day away but is arousable. All of the above A and B only Discussion: Which criteria are met? What are the red flags? On a CAM assessment, is the 1 and 2 and 3 or 4 criteria for delirium met? What actions might you consider taking?
