Abstract:
Purpose:: This study examined the effects of a multimodal intervention (earplugs, eye patches, and aromatherapy) on sleep quality and duration in intensive care unit(ICU)patients and the feasibility of the intervention to address sleep disturbances.
Methods:: This experimental study comprised a nonequivalent control group and non-synchronized design. The participants included 50 adult patients admitted to the ICU with an internal medicine diagnosis who did not receive postoperative care. The intervention was conducted on a random day from 10 pm to 5 am the following morning. Subjective sleep quality was measured using the Korean version of the Richards–Campbell Sleep Questionnaire, and objective sleep duration was recorded using a smartwatch (Galaxy Watch 5; Samsung Electronics). Data were collected from September 2023 to March 2024 and analyzed using a t-test, χ2 test, Fisher’s exact test, and analysis of covariance.
Results:: The multimodal intervention significantly improved the subjective andobjective measures of sleep quality. The experimental group had higher scores on sleep depth, falling asleep, sleeping without awakening, returning to sleep, and overall sleep quality. Objective measures revealed longer total sleep time, actual sleep time, light sleep, and deep sleep in the experimental group, with no differences in rapid eye movement sleep, sleep efficiency, or ratio of awakening.
Conclusion:: The multimodal sleep intervention effectively improved patients’ sleep quality and duration, demonstrating the feasibility of using multimodal interventions to improve sleep quality in clinical settings.
