Study Notes

Overview of Delirium

Delirium is an abrupt, transient change in mental state and consciousness marked by disorganized thinking, disorientation, and perceptual disturbances.
It often presents with symptoms like restlessness, agitation, and emotional lability.

Causes and Risk Factors

Delirium generally indicates a reversible but life-threatening condition.
Risk factors include advanced age, chronic illnesses, new or exacerbated health issues, substance use, and environmental changes, particularly hospitalization.
Common precipitating conditions: infections, metabolic imbalances, trauma, nutritional deficiencies, CNS diseases, and exposure to toxins.

Pathophysiology

Delirium is associated with increased cerebral oxidative stress and impaired neurotransmitter function.
Sympathetic nervous system activation disrupts cholinergic transmission, diminishing cerebral function and arousal mechanisms.

Prevalence and Demographics

Higher incidence observed in older adults, especially those with dementia.
Delirium occurs in approximately 50% of postoperative patients and 82% of ICU patients.

Clinical Manifestations

Symptoms vary, including reduced awareness, impaired thinking, fluctuating activity levels, and behavior.
Patients may experience "sundowning," where confusion worsens in the evening.
Psychomotor activity can be hyperactive, hypoactive, or mixed throughout the day.

Diagnosis

Diagnosis begins with a physical exam and detailed medical history, often utilizing the CAM test to differentiate between delirium and other impairments.
Additional assessments may include drug and alcohol screening, neurologic exams, and laboratory tests for infections or metabolic imbalances.

Treatment Approaches

Pharmacologic Therapy

Antipsychotics are prescribed for underlying psychotic symptoms.
Mood stabilizers like lithium are used for mania or mood swings, while nonpharmacologic therapy may involve stopping certain medications causing delirium.

Nonpharmacologic Therapy

Emphasizes management of risk factors: addressing immobility, dehydration, sleep deprivation, and sensory impairments.
Physical interventions may include oxygen therapy, IV fluids, and proper nutrition to enhance cognitive function.
Environmental modifications ensure patient comfort to minimize confusion, focusing on stimulation control and safety.
Cognitive strategies involve orienting patients to time, place, and identity, offering reassurance to help resolve delirium.

Prevention

Focuses on identifying and mitigating risk factors, enhancing early detection, and applying holistic management strategies.
Proper medical oversight for individuals with predisposing conditions can lower delirium risk.

Family Involvement and Education

Educate patients and families on the risks and symptoms of delirium to enhance awareness.
Assist in creating a tailored action plan addressing potential hyperglycemic or hypoglycemic episodes.

Evaluation Criteria

Ensure the patient sustains no injuries during hospitalization.
Confirm patients are oriented to time, place, date, and person, or have returned to their baseline cognitive state.
Monitor for absence of delirium symptoms possibly resulting from hospitalization or poorly managed chronic conditions.
Assess patient communication for clarity and logical transitions during interactions.
Verify patient capability to perform Activities of Daily Living (ADLs) or return to baseline functioning.

Ongoing Risk Consideration

Recognize that even after cognitive status improves, patients still remain at risk for future episodes of delirium.
