Introduction: HD unit is a noisy environment for patients, and noise can affect anxiety levels and sleep quality. Methods: The aim of the study is to determine noise level, the relationship between noise levels, and sleep quality and anxiety in patients in HD unit. A descriptive and observational study design was used. Three Benetech GM1351 manual sound-level meters were used to measure noise. A patient information form, the State Anxiety Inventory, and the modified Post-Sleep Inventory were used for data collection. Results:The noise range detected in the HD unit ranges from 48.40 to 72 dB (A). Our findings show that patients in the HD unit are exposed to high noise levels and the noise significantly negatively impacts quality of sleep and anxiety level of the patients. Conclusions: It is important to be aware that HD patients are constantly exposed to high levels of noise and to plan nursing interventions to reduce this noise level.

“…Noise levels in ICUs have been reported to exceed average values 34 . Demir and Öztunç investigated the effect of noise on nocturnal sleep and vital signs in intensive care patients and reported a mean noise level of 52.04 ± 5.75 dB, while Terzi et al reported a mean level of 71 dB and Garrido Galindo et al a mean level of 64.00 ± 3.62 dB(A) (maximum 76.04 ± 5.73 dB, minimum 54.84 ± 2.61 dB), all above average values 10,35,36 . The WHO has reported a maximum tolerable level of 50 to 55 dB(A) 7,10 .…”

Background Intensive care is a noisy environment for patients and one that affects pain, anxiety levels, and sleep quality. Aims and objectives To determine the relationship between noise levels and pain, anxiety, and sleep levels in patients in intensive care units. Design A descriptive and observational study design was used. Methods This study was conducted between June and December 2018 in a public hospital and included 111 patients admitted to surgical critical care for at least 24 hours. Three Benetech Gm1351 manual sound level metres were used to measure noise. A Patient Information Form, a pain Visual Analog Scale (VAS), the Spielberger State‐Trait Anxiety Inventory, and the Richards Campbell Sleep Questionnaire (RCSQ) were used for data collection. Results The mean age of the patients was 57.29 years. The mean noise level detected in the intensive care unit was 66.52 dB (dB). Patients' mean pain VAS score was 3.79 ± 1.72, the mean State Anxiety Inventory score was 39.74 ± 2.98, and the mean total RCSQ score was 25.10 ± 13.17. Our findings show that patients in the intensive care unit are exposed to high noise levels and that, while this has no effect on pain, it significantly impacts anxiety and quality of sleep. Conclusions Noise levels in intensive care units significantly exceed recommended thresholds, and this adversely affects patients' anxiety levels and sleep quality. It is important for suitably restful conditions to be provided for patients, to be aware of the potential for anxiety, and for these factors to be borne in mind when planning nursing interventions. Relevance to clinical practice Further studies on the effects of noise levels on pain, anxiety, and sleep levels in patients admitted to intensive care units are needed.

Aim:The aim of this study was to evaluate the quality of sleep in critically ill patients in the Intensive Care Unit (ICU). Method and Material:This study investigated the night-time sleep of 135 patients admitted to the general ICU of the General Hospital of Athens G. Gennimatas between January 2021 and December 2023. Data were collected using the Richards Campbell Sleep Questionnaire (RCSQ). Sensory stimuli, including noise, light, nursing activities, and invasive procedures, were reduced during the night to improve patients sleep. Measures to reduce light included implementing special lighting during nursing tasks and using bedside lamps during care. Noise reduction strategies involved closing doors, minimizing monitor alarms, and discouraging staff from speaking near patient beds. Grouping patient care activities was also promoted to limit sleep disturbances. Results:Patients in the intervention group showed improved sleep quality compared to the control group, with a significant overall RCSQ score (p<0.05). Gender and age did not significantly affect sleep quality. However, hospital stay duration differed between groups, with the control group experiencing shorter stays. A negative correlation was observed between the duration of hospitalization and sleep quality, with longer stays linked to lower RCSQ scores. Additionally, extended mechanical ventilation was associated with poorer sleep quality. Conclusion: Patients in the ICU often exhibit abnormal levels of alertness, poor quality of daytime sleep, disrupted nighttime sleep, and sleep patterns that lack both slow-wave and rapid eye movement (REM) sleep. Gaining a deeper understanding of the role circadian rhythms play in managing critical illness could pave the way for future chronotherapeutic strategies, enhancing clinical outcomes and promoting recovery for patients.
