Management of Sleep Disturbances in Elderly Patients with Renal Impairment

Immediate Safety Concerns

The American Geriatrics Society recommends extreme caution with benzodiazepines in elderly patients, and this patient's lorazepam should be tapered and discontinued due to the high fall risk 1, 2
Multiple medications in this regimen, including carvedilol, chlorthalidone, duloxetine, and hydralazine, disrupt sleep, contributing to sleep disturbances 1, 4

Cognitive behavioral therapy for insomnia (CBT-I) should be initiated immediately as the most effective treatment with sustained benefits, according to the American Geriatrics Society 1, 2
Sleep hygiene education, including regular morning or afternoon exercise, daytime bright light exposure, and avoiding heavy meals near bedtime, is essential for improving sleep quality 5

The American Geriatrics Society recommends tapering and discontinuing lorazepam using a slow reduction schedule to avoid withdrawal seizures 2, 3
The patient's gabapentin dose should be reduced based on calculated creatinine clearance, with close monitoring for continued sedation, confusion, and ataxia, as recommended by the American Geriatrics Society 1, 4

The patient should be screened for obstructive sleep apnea (OSA) and restless legs syndrome (RLS), as these conditions can contribute to sleep disturbances, according to the European Urology guidelines 5, 6
The combination of depression, anxiety, OCD, and insomnia suggests comorbid psychiatric illness, and untreated insomnia is a risk factor for recurrent depression, as noted by the American Geriatrics Society 1, 4

The patient should be monitored vigilantly for respiratory depression, confusion or delirium, falls and fractures, next-day cognitive impairment, and worsening dementia symptoms during any medication changes, as recommended by the American Geriatrics Society 1, 2
Sleep efficiency and latency should be assessed, with <80% efficiency and >30 minutes latency associated with increased mortality risk in older adults, according to the American Geriatrics Society 1

The American Geriatrics Society recommends never starting with pharmacotherapy instead of CBT-I in elderly patients with multiple comorbidities and renal impairment 2
The patient's sedative medications should be reduced by at least 50% due to renal impairment, and benzodiazepines should never be abruptly discontinued due to seizure risk, as recommended by the American Geriatrics Society 2, 3
