Sleep is a biological necessity, and adequate sleep is important for neurocognitive health and well-being. Family members of intensive care patients may lack adequate sleep either due to the intensive care unit (ICU) environment (lack of opportunities for sleep) or due to stress and anxiety (i.e., insomnia). Moreover, difficulty sleeping may persist after ICU discharge. In addition to reviewing the key literature, we propose a model for family education and engagement to optimize sleep for family members and patients in the ICU. This model may aid in family member engagement with clinicians and may ultimately alleviate symptoms of difficulty sleeping and post-intensive care syndrome in caregivers after the ICU.
