The Effect of Pink Noise and the Quiet Night Intervention on Sleep Parameters in Intensive Care Unit Patients: A Single-Center Randomized Controlled Trial

Condition(s) studied

Investigational drug(s) / intervention(s)

Acoustic Noise Masking Intervention: Environmental acoustic noise masking applied before and during nighttime sleep to reduce ambient ICU noise and support sleep continuity.

Quiet Night Intervention: A quiet night protocol including environmental noise and light reduction supported by earplugs and an eye mask.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Sleep Efficiency — Single night (23:00-06:00)
  Sleep efficiency will be measured using a single wrist-worn actigraphy device (smartwatch) during nighttime sleep (23:00-06:00).
