Management of Drowsiness in CKD Patients on Hemodialysis

Optimize Dialysis Prescription

• The American Society of Nephrology recommends increasing dialysis frequency to at least three times weekly, as twice-weekly dialysis is only appropriate for patients with substantial residual kidney function, which is unlikely in advanced CKD 1
• Extended or more frequent hemodialysis (4-6 times weekly) may further improve uremic symptoms and quality of life, though evidence certainty is low 1
• Achieve and maintain target dry weight through adequate ultrafiltration, as volume overload contributes to cardiovascular symptoms and overall symptom burden, according to the National Kidney Foundation 2, 4

Systematic Assessment of Drowsiness and Contributing Factors

• Use validated screening tools, such as the Edmonton Symptom Assessment System-revised: Renal (ESAS-r:R), to quantify drowsiness severity and identify concurrent symptoms, as recommended by the American Academy of Sleep Medicine 1
• The Pittsburgh Sleep Quality Index (PSQI) with scores ≥5 indicates poor sleep quality, which affects 65-83% of dialysis patients and contributes to daytime drowsiness, according to the American Academy of Sleep Medicine 1

Pharmacologic Management

• The American College of Physicians recommends gabapentin 100-300 mg administered after each dialysis session as the preferred pharmacologic agent for neurologic and sleep-related symptoms in dialysis patients, with proven efficacy and favorable safety profile 1, 3

Non-Pharmacologic Interventions

• Cognitive behavioral therapy (CBT) has proven efficacy in reducing depression and may improve sleep quality, thereby reducing daytime drowsiness, according to the American Psychological Association 1
• Aerobic exercise decreases depressive symptoms and may improve sleep quality (moderate certainty evidence), as recommended by the American Heart Association 1

Medication Timing Considerations

• Administer cardiovascular medications at night to avoid intradialytic hypotension, which can cause post-dialysis fatigue and drowsiness, according to the American Heart Association 4

Monitoring and Follow-Up

• Reassess drowsiness severity at each dialysis visit using standardized tools, as recommended by the American Society of Nephrology 1
• Evaluate medication efficacy and adverse effects, especially cognitive changes and falls, according to the American Geriatrics Society 1, 3

Red Flags Requiring Urgent Escalation

• Escalate care urgently if drowsiness is accompanied by altered mental status or confusion, seizure activity, severe electrolyte abnormalities, volume overload refractory to current dialysis prescription, or progressive nutritional deterioration, as recommended by the American College of Emergency Physicians 1, 3
