A pharmacist's guide to mitigating sleep dysfunction and promoting good sleep in the intensive care unit.

Abstract

Purpose: To review causes, risk factors, and consequences of sleep disruption in critically ill patients; evaluate the role of nonpharmacological and pharmacological therapies for management of sleep in the intensive care unit (ICU); and discuss the role of pharmacists in implementation of sleep bundles.

Summary: Critically ill patients often have disrupted sleep and circadian rhythm alterations that cause anxiety, stress, and traumatic memories. This can be caused by factors such as critical illness, environmental factors, mechanical ventilation, and medications. Methods to evaluate sleep, including polysomnography and questionnaires, have limitations that should be considered. Multicomponent sleep bundles with a focus on nonpharmacological therapy aiming to reduce nocturnal noise, light, and unnecessary patient care may improve sleep disorders in critically ill patients. While pharmacological agents are often used to facilitate sleep in critically ill patients, evidence supporting their use is often of low quality, which limits use to patients who have sleep disruption refractory to nonpharmacological therapy. Dedicated interprofessional teams are needed for implementation of sleep bundles in the ICU. Extensive pharmacotherapeutic training and participation in daily patient care rounds make pharmacists vital members of the team who can help with all components of the bundle. This narrative review discusses evidence for elements of the multicomponent sleep bundle and provides guidance on how pharmacists can help with implementation of nonpharmacological therapies and management of neuroactive medications to facilitate sleep.

Conclusion: Sleep bundles are necessary for patients in the ICU, and dedicated interprofessional teams that include pharmacists are vital for successful creation and implementation.
