Data were collected from the EICU of a tertiary hospital in South Korea between October 2025 and March 2026. A total of 48 patients were included, with 24 each in the experimental and control groups. The 2-day intervention comprised delirium prevention, sleep promotion, and intervention adherence management. Delirium was assessed using the Korean Nursing Delirium Screening Scale, sleep quality using the Korean version of the Richards-Campbell Sleep Questionnaire, and total sleep time was measured using a wearable device. Data were analyzed using generalized estimating equations, analysis of covariance (ANCOVA), and two-way repeated-measures ANCOVA using SPSS version 26.0 program.Results: Delirium scores were significantly lower in the experimental group than in the control group, with significant group (\u03c72 = 5.21, p = .022), time (\u03c72 = 12.86, p = .005), and group-by-time interaction effects (\u03c72 = 10.76, p = .013). Adjusted post-test sleep quality was significantly higher in the experimental group than in the control group (F = 16.15, p &lt; .001, partial \u03b72 = .26). Total sleep time showed significant main effects of group and time, whereas the group-by-time interaction was not significant (F = 2.61, p = .113, partial \u03b72 = .05).Conclusion: The intervention helped prevent increases in delirium scores and improved sleep quality among EICU patients. This intervention may provide a feasible nursing strategy for critical care settings without the need for specialized equipment.<\/jats:p>","DOI":"10.7586\/jkbns.26.034","type":"journal-article","created":{"date-parts":[[2026,8,27]],"date-time":"2026-08-27T00:53:26Z","timestamp":1787792006000},"page":"401-412","update-policy":"https:\/\/doi.org\/10.7586\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects
