Introduction Intensive care nurses face several challenges to facilitating sleep in their critically ill patients. With its high noise levels, hectic around-the-clock activity and constant artificial lights, the intensive care environment does not foster sleep. Intensive care unit patients have significant alterations in their sleep architecture with frequent awakenings and lighter sleep; up to 50% of this sleep also occurs during the daytime. Sleep loss increases the risk of developing delirium (especially in elderly patients) and immune system impairment, which prolongs healing. The aim of this article was to develop an evidence-based bundle of nursing care activities that promote adult intensive care patients’ sleep. Methods A broad search was conducted in PubMed, CINAHL, Cochrane Library, and McMaster plus using search words and Medical Subject Headings terms, such as sleep, intensive care unit, intensive care, critical care nursing, sleep promotion, music, white noise, earplugs, pain relief, absence of pain, nonpharmacological intervention, and mechanical ventilation. Eight recommendations emerged from this review: reduce noise, use earplugs and eye masks, use music, promote a natural circadian rhythm, manage pain, use quiet time, cluster nursing care activities at night, and optimize ventilator modes. Conclusion Promoting sleep within this patient population needs to be a higher priority for intensive care nurses. Sleep should be a focus throughout the day and night, in order to sustain patients’ natural circadian rhythms. Novel research in this field could change the strength of these recommendations and add new recommendations to the bundle.
