The Effects of Background Noise for Adult Patients' Sleep Quality in Intensive Care Unit.
Study Details
Study Description
Brief Summary
Poor sleep quality is one of the most common problems among adult patients in the intensive care unit (ICU). The causes of sleep disturbance are complicated. Poor sleep quality can lead to negative consequences for patients' physical and mental health. Non-pharmacological interventions, such as background noise, have been recommended to increase the threshold level of sound during nighttime and achieve masking effects to improve subjective sleep quality. This study is a randomized controlled trial that compared two parallel patient groups.The hypothesis of this study is that background noise can improve sleep quality in adult ICU patients compared with conventional treatment group.

Detailed Description
Poor sleep quality is one of the most common problems among adult patients in the intensive care unit (ICU). Statistics indicate that over 50% of ICU patients report sleep abnormalities, such as sleep fragmentation, arousals, frequent awakenings, and poor sleep quality. The causes of sleep disturbance are complicated, with evidence suggesting that environmental factors such as noise, from alarms and machines that are active around the clock in the ICU, play a significant role. Poor sleep quality can lead to negative consequences for patients' physical and mental health.
Sleep promotion interventions, including both pharmacological and non-pharmacological approaches, have been proposed. However, the side effects of pharmacological intervention may also lead to poor outcomes. Therefore, non-pharmacological interventions, such as background noise, have been recommended to increase the threshold level of sound during nighttime and achieve masking effects to improve subjective sleep quality.
This study was conducted in randomized controlled trial that compared two parallel patient groups. Patients were included by convenience sampling in a medical center in Taiwan. The Verran and Snyder-Halpern Sleep Scale (VSHSS) was used to assess subjective sleep quality. The main purpose of this study was to investigate the effect of background noise intervention in sleep quality in adult intensive care unit patients.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: background noise group Background noise at bedtime. |
Other: background noise
Using sound machine for 3 days at bedtime for 7 hours(11p.m.- 6a.m.) in a decibel of 40-50.
|
| No Intervention: conventional treatment group Treatment as usual. |
Outcome Measures
Primary Outcome Measures
- The Verran and Snyder-Halpern Sleep Scale scores changed from baseline to 1st days, 3rd days and 5th days. [Baseline, 1st days, 3rd days and 5th days.]
Sleep quality is accessed by using Verran and Snyder-Halpern(VSH) Sleep Scale, a subjective sleep scale contains three dimensions: sleep disturbance, sleep effectiveness and sleep supplementation with totally 15 items. Scores were measured by using visual analogue scale which is a 100mm horizontal lines. The maxium score is 100 and the minimum score is 0. Totally score of VSHSS range from 0 to 1500. The lower of the score, the poorer of the sleep quality.
