Sleep disruption is common in adult intensive care unit (ICU) patients and is often worsened by environmental noise and nighttime care activities. Poor sleep may negatively affect recovery and well-being.
This single-center, three-arm randomized controlled trial will evaluate the short-term effects of two non-pharmacological interventions-(1) pink-brown noise masking and (2) a quiet time intervention-on objective sleep parameters in adult ICU patients, compared with standard care.
Sleep outcomes will be measured using actigraphy-based wearable monitoring, including total sleep time, sleep efficiency, sleep onset latency, wake after sleep onset, and number of awakenings. Results are expected to support evidence-based nursing approaches to improve sleep in ICU patients.
Adults aged 18 years and older
Patients admitted to the adult intensive care unit
Expected ICU stay of at least one night
Ability to tolerate non-invasive sleep-related interventions (earplugs, eye mask, or acoustic masking)
Severe hearing impairment preventing use of acoustic interventions
Severe cognitive impairment or coma preventing sleep assessment
Use of continuous deep sedation
Diagnosed sleep disorders requiring pharmacological treatment
