Abstract
BACKGROUND Patients in intensive care units are exposed to many factors that can negatively affect the quality of their sleep. OBJECTIVE To describe the latest findings regarding sleep quality improvement in intensive care unit patients. METHODS An integrative literature review was conducted in the CINAHL, PubMed, Cochrane Library, and MEDLINE databases in April and May 2023. The following keywords were used: intensive care units, promotion, sleep quality, and sleep. The Critical Appraisal Skills Programme tool was used to assess the quality of individual studies. RESULTS Of 159 articles identified, 10 were included in the final analysis. The findings were grouped into 4 thematic categories: consequences of poor sleep quality, factors affecting sleep quality, pharmacologic ways to improve sleep quality, and nonpharmacologic ways to improve sleep quality. DISCUSSION Various pharmacologic and nonpharmacologic treatments are used in clinical settings. Nonpharmacologic interventions include sleep masks, earplugs, reductions in alarm volume, and reductions in nighttime interventions. Relaxation techniques include aromatherapy, music therapy, and acupressure. CONCLUSIONS The most effective way to improve sleep for intensive care unit patients is to use a combination of pharmacologic and nonpharmacologic interventions. Among the latter, the use of earplugs and sleep masks is simplest.

Abstract
Circadian rhythms in humans are biological rhythms that regulate various physiological processes within a 24-hour time frame. Critical illness can disrupt the circadian rhythm, as can environmental and clinical factors, including altered light exposure, organ replacement therapies, disrupted sleep-wake cycles, noise, continuous enteral feeding, immobility, and therapeutic interventions. Nonpharmacological interventions, controlling the ICU environment, and pharmacological treatments are among the treatment strategies for circadian disruption. Nutrition establishes biological rhythms in metabolically active peripheral tissues and organs through appropriate synchronization with endocrine signals. Therefore, adhering to a feeding schedule based on the biological clock, a concept known as "chrononutrition," appears to be vitally important for regulating peripheral clocks. Chrononutritional approaches, such as intermittent enteral feeding that includes overnight fasting and consideration of macronutrient composition in enteral solutions, could potentially restore circadian health by resetting peripheral clocks. However, due to the lack of evidence, further studies on the effect of chrononutrition on clinical outcomes in critical illness are needed. The purpose of this review was to discuss the role of chrononutrition in regulating biological rhythms in critical illness, and its impact on clinical outcomes.

Analysis of the factors influencing of sleep quality in intensive care unit awake patients based on a structural equation model: A cross-sectional study. J Clin Nurs 2024. [PMID: 38797951 DOI: 10.1111/jocn.17311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 05/13/2024] [Accepted: 05/21/2024] [Indexed: 05/29/2024]
Abstract
OBJECTIVE The objective of this study was to construct and validate a structural equation model (SEM) to identify factors associated with sleep quality in awake patients in the intensive care unit (ICU) and to assist in the development of clinical intervention strategies. RESEARCH METHODS/SETTING In this cross-sectional study, 200 awake patients who were cared for in the ICU of a tertiary hospital in China were surveyed via several self-report questionnaires and wearable actigraphy sleep monitoring devices. Based on the collected data, structural equation modelling analysis was performed using SPSS and AMOS statistical analysis software. The study is reported using the STROBE checklist. RESULTS The fit indices of the SEM were acceptable: χ2/df = 1.676 (p < .001) and RMSEA = .058 (p < 0.080). Anxiety/depression had a direct negative effect on the sleep quality of awake patients cared for in the ICU (β = -.440, p < .001). In addition, disease-freeness progress had an indirect negative effect on the sleep quality of awake patients cared for in the ICU (β = -.142, p < .001). Analgesics had an indirect negative effect on the sleep quality of awake patients cared for in the ICU through pain and sedatives (β = -.082, p < .001). Sedation had a direct positive effect on the sleep quality of conscious patients cared for in the ICU (β = .493; p < .001). CONCLUSION The results of the SEM showed that the sleep quality of awake patients cared for in the ICU is mainly affected by psychological and disease-related factors, especially anxiety, depression and pain, so we can improve the sleep quality of patients through psychological intervention and drug intervention.

Abstract
INTRODUCTION Sleep deprivation is rampant within the military population, and insufficient sleep can lead to physical and mental health problems impacting soldier's readiness and deployability. Past research has shown the importance of leadership's role in subordinates' sleep health. Understanding the values, beliefs, and quality of military leader sleep is essential to the development of effective interventions to optimize occupational performance and overall sleep health. Therefore, the purpose of this study was to examine the military leaders' values, beliefs, and sleep quality and the impact on occupational performance. The authors aimed to (1) identify military leaders' sleep quality and beliefs; (2) explore the relationship between military leaders' sleep quality, beliefs and attitudes about sleep, and impact on occupational performance; and (3) examine the value leaders place on sleep for themselves and subordinates in relation to occupational performance. MATERIALS AND METHODS This observational, mixed-methods study design recruited a convenience sample of 109 Army active duty medical service members currently serving in a leadership role. Participants completed an electronic survey to include general demographic information and three self-report measures: the Pittsburgh Quality of Sleep Index, the Dysfunctional Beliefs about Sleep, and the Functional Outcomes of Sleep Questionnaire. Eleven participants completed the semi-structured qualitative interview focusing on sleep values and the impacts on performance. Univariate and multivariate regressions were performed for statistical analysis of the quantitative survey data, whereas thematic analysis was used to analyze the qualitative interview data. This study was approved by the U.S. Army Medical Center of Excellence Institutional Review Board. RESULTS Multivariate regression analysis demonstrated small-to-medium effect sizes (R2 = 0.355-0.559) for relationships between sleep quality, sleep beliefs, functional performance, and demographic variables. More specifically, military grade, position, use of alcohol, time in service, and gender were all found to contribute significantly to scores on the Pittsburgh Sleep Quality Index, the Dysfunctional Beliefs About Sleep Scale-16, and the Functional Outcomes of Sleep Questionnaire-10 (P < .05). Qualitative data resulted in three primary themes: (1) Poor sleep degrades performance, (2) sleep is a top priority, and (3) leaders have a responsibility for subordinates' sleep health. CONCLUSIONS This sample of military leaders was found to perceive themselves as poor-quality sleepers despite demonstrating more functional attitudes and beliefs about sleep and reporting normal-to-mild impairments in daily functioning as a result of daytime sleepiness. Furthermore, findings suggest that leaders' sleep quality and beliefs stand to be further improved, whereas their sleep values need to be consistently demonstrated to subordinates. With a clearer understanding of military leaders' values, beliefs, and sleep quality, future research could focus on implementing and developing holistically based and individualized sleep interventions intended to optimize performance and sleep health.

Abstract
Ubiquitous environmental exposures increase cardiovascular disease risk via diverse mechanisms. This review examines personal strategies to minimize this risk. With regard to fine particulate air pollution exposure, evidence exists to recommend the use of portable air cleaners and avoidance of outdoor activity during periods of poor air quality. Other evidence may support physical activity, dietary modification, omega-3 fatty acid supplementation, and indoor and in-vehicle air conditioning as viable strategies to minimize adverse health effects. There is currently insufficient data to recommend specific personal approaches to reduce the adverse cardiovascular effects of noise pollution. Public health advisories for periods of extreme heat or cold should be observed, with limited evidence supporting a warm ambient home temperature and physical activity as strategies to limit the cardiovascular harms of temperature extremes. Perfluoroalkyl and polyfluoroalkyl substance exposure can be reduced by avoiding contact with perfluoroalkyl and polyfluoroalkyl substance-containing materials; blood or plasma donation and cholestyramine may reduce total body stores of perfluoroalkyl and polyfluoroalkyl substances. However, the cardiovascular impact of these interventions has not been examined. Limited utilization of pesticides and safe handling during use should be encouraged. Finally, vasculotoxic metal exposure can be decreased by using portable air cleaners, home water filtration, and awareness of potential contaminants in ground spices. Chelation therapy reduces physiological stores of vasculotoxic metals and may be effective for the secondary prevention of cardiovascular disease.

Abstract
In intensive care units, environmental factors like loud noises and bright lights can cause fear, anxiety, changes in vital signs, and sleep disturbances. The aim of this study was to find out how using earplugs and eye masks during the night affected sleep quality, anxiety, fear, and vital signs of patients in an intensive care unit. A total of 70 patients, 35 in the intervention and 35 in the control group, were included in this randomised controlled study. While the patients in the intervention group were provided with earplugs and eye masks for 3 nights in addition to their routine care, only routine care was given to the patients in the control group. The 'Introductory Information Form', 'Visual Analogue Scale-Fear (VAS-F)', 'Visual Analogue Scale-Anxiety (VAS-A)', 'Vital Signs Monitoring Form', and 'Richards-Campbell Sleep Questionnaire' were used for data collection. It was found that the mean scores of VAS-F, VAS-A, heart rate, diastolic and systolic blood pressure of the intervention group decreased significantly after the intervention, while their sleep quality increased significantly. In this study, it was found that using earplugs and eye masks for patients in an intensive care unit during the night was effective in improving patients' sleep quality and reducing fear, anxiety, and problems in vital signs.

Abstract
This study was conducted to determine the effects of the use of ergonomic sleep mask on sleep quality and comfort in intensive care patients. This randomised controlled experimental study was completed with 128 surgical intensive care patients (control = 64, experimental = 64). During the second night of their stay in the unit, ergonomic sleep masks were given to the patients in the experimental group, and earplugs and eye masks were given to the patients in the control group. A Patient information form, Visual analogue scale for discomfort, and the Richard-Campbell sleep questionnaire were used to collect data. While 51.6% of the patients were female, the mean age of the patients was 63.87 ± 14.94 years. The highest rates of patients had undergone cardiovascular surgery (28.9%) and general anaesthesia (57.8%). It was determined that the sleep quality of the patients in the experimental group was statistically and clinically significantly higher after the intervention (50.86 ± 21.46 vs 37.64 ± 14.97, t = -5.355, Cohen's d = 0.450, p < 0.001). Likewise, the patients who used ergonomic sleep masks had a statistically significantly lower mean VAS for Discomfort score, and their comfort level was higher (p < 0.001), but the difference was not clinically significant (Cohen's d = 0.208). The results of this study showed that the use of ergonomic sleep masks in surgical intensive care patients had a more positive effect on both the sleep quality and comfort levels of patients compared with earplugs and eye masks. The use of an ergonomic sleep mask is recommended in the early period to facilitate sleep and rest in surgical intensive care patients.

Abstract
AIMS To determine the effectiveness of non-pharmacological interventions on sleep outcomes among patients with coronary artery disease and recognize pertinent characteristics that potentially affect the effectiveness of such interventions. METHODS AND RESULTS Relevant studies conducted before 27 April 2022 were identified through four core electronic databases using terms related to coronary artery disease, sleep outcomes, and randomized controlled trials. Two authors independently conducted study selection, data extraction, and risk-of-bias assessment. Meta-analysis, sub-group analysis, publication bias analysis, and sensitivity analysis were conducted using R version 4.2.2. Of the 4755 retrieved articles, 42 studies were selected for systematic review and 30 studies were included in the meta-analysis. The findings of this study revealed that non-pharmacological interventions significantly improved self-reported sleep quality (standardized mean difference = -0.85, 95% confidence interval -1.08, -0.63), but had no effects on objectively measured sleep efficiency and duration. Regarding the types of interventions involved, environmental control was the most effective in improving self-reported sleep quality, followed by relaxation, self-care behaviour management, and relaxation and cognitive/psychological complex interventions. Through subgroup analysis, we did not find any covariates that were significantly related to self-reported sleep quality. CONCLUSION Non-pharmacological interventions have been shown to play beneficial roles in improving self-reported sleep quality among patients with coronary artery disease. Additional studies are required to elucidate the effect of non-pharmacological interventions on objectively measured sleep outcomes and to characterize their optimal frequencies and durations.

Abstract
BACKGROUND Delirium, which is frequently encountered in intensive care patients, can be prevented with multicomponent nursing interventions, and thus the negative consequences can be reduced. AIM To examine the effect of using eye masks and earplugs in preventing delirium in intensive care units (ICUs). STUDY DESIGN A randomized, controlled, single-blind intervention study. This study was conducted in the medical and surgical ICUs of a tertiary hospital, and nurses were given pre-study training on delirium risks, diagnosis, prevention, and management. Data were collected using the patient information form, the Nursing Delirium Screening Scale, the Richard-Campbell Sleep Scale, and the daily follow-up form. Various environmental modifications were made in the ICUs for all patients, and evidence-based nonpharmacological nursing interventions were applied to the patients in both groups during the day and night shifts for 3 days. In addition, the patients in the intervention group were provided with eye masks and earplugs for three nights. RESULTS The study included a total of 60 patients (30 in the intervention group and 30 in the control group). There was a statistically significant difference in the development of delirium between the intervention and control groups (night of the 2nd day, p = .019; day of the 3rd day p < .001; night of the 3rd day p ≤ .001). The average total sleep quality score of the intervention group was found to be significantly higher than the control group (p ≤ .001 for three nights). Staying in the internal medicine ICU affected (odds ratio [OR], 11.84; 95% confidence interval [CI], 3.00-46.66; p = .017) more on the development of delirium than in coronary ICU, being in the age group of 65 and over, having a hearing impairment, coming to ICU from the operating room, and education level had an effect. CONCLUSIONS The earplugs and eye masks used by the intensive care patients overnight were found to be effective in increasing sleep quality and preventing delirium. RELEVANCE TO CLINICAL PRACTICE The use of eye masks and earplugs is recommended for ICUs in preventing delirium.

Abstract
Background: Sleep and circadian disruption (SCD) is common and severe in the ICU. On the basis of rigorous evidence in non-ICU populations and emerging evidence in ICU populations, SCD is likely to have a profound negative impact on patient outcomes. Thus, it is urgent that we establish research priorities to advance understanding of ICU SCD. Methods: We convened a multidisciplinary group with relevant expertise to participate in an American Thoracic Society Workshop. Workshop objectives included identifying ICU SCD subtopics of interest, key knowledge gaps, and research priorities. Members attended remote sessions from March to November 2021. Recorded presentations were prepared and viewed by members before Workshop sessions. Workshop discussion focused on key gaps and related research priorities. The priorities listed herein were selected on the basis of rank as established by a series of anonymous surveys. Results: We identified the following research priorities: establish an ICU SCD definition, further develop rigorous and feasible ICU SCD measures, test associations between ICU SCD domains and outcomes, promote the inclusion of mechanistic and patient-centered outcomes within large clinical studies, leverage implementation science strategies to maximize intervention fidelity and sustainability, and collaborate among investigators to harmonize methods and promote multisite investigation. Conclusions: ICU SCD is a complex and compelling potential target for improving ICU outcomes. Given the influence on all other research priorities, further development of rigorous, feasible ICU SCD measurement is a key next step in advancing the field.

Abstract
Sleep deficiency is a common problem in the hospital setting. Contributing factors include preexisting medical conditions, illness severity, the hospital environment, and treatment-related effects. Hospitalized patients are particularly vulnerable to the negative health effects of sleep deficiency that impact multiple organ systems. Objective sleep measurement is difficult to achieve in the hospital setting, posing a barrier to linking improvements in hospital outcomes with sleep promotion protocols. Key next steps in hospital sleep promotion include improvement in sleep measurement techniques and harmonization of study protocols and outcomes to strengthen existing evidence and facilitate data interpretation across studies.

Abstract
Sleep is disturbed in critically ill patients and is a frequently overlooked complication. The aim of our study is to evaluate the impact of sound levels in our surgical ICU on our patients’ sleep on the first night of admission. The study was performed in a tertiary care university hospital, in a 12-bed surgical ICU. Over a 6-week period, a total of 148 adult, non-intubated and non-sedated patients completed the study. During this six-week period, sound levels were continuously measured using a type II sound level meter. Sleep quality was evaluated using the Richards–Campbell Sleep Questionnaire (RCSQ), which was completed both by patients and nurses on the first morning after admission. A non-significant correlation was found between night sound levels and sleep quality in the overall sample (r = −1.83, 95% CI; −4.54 to 0.88, p = 0.19). After multivariable analysis, a correlation was found between higher sound levels at night and lower RCSQ evaluations (r = −3.92, 95% CI; −7.57 to −0.27, p = 0.04). We found a significant correlation between lower sound levels at night and a better quality of sleep in our patients; for each 1 dBA increase in LAFeq sound levels at night, patients scored 3.92 points lower on the sleep questionnaire.

Abstract
Sleep is an essential need for patients admitted to coronary care units. The present clinical trial aimed to determine the effect of using eye masks and earplugs on the sleep quality of patients with coronary heart disease (CHD). A total of 68 eligible patients with CHD were randomly allocated into four groups of 17 (control, eye masks, earplugs, and eye masks with earplugs). All three interventions were performed during the night from 10:00 p.m. to 7:00 a.m. the next day. The outcomes were the quality of sleep, measured by the Verran and Snyder-Halpern (VSH) Sleep Scale, and the urinary levels of nocturnal melatonin and cortisol, measured by urine samples taken during the night (from 10:00 p.m. to 7:00 a.m.). The study outcomes were measured on the third and fourth days. Sleep disturbance was statistically significantly lower in patients with earplugs (visual analogue scale mean difference [MD]: 74.31 mm, SE: 11.34, p = 0.001). Sleep effectiveness was statistically significantly higher in patients with eye mask (MD: 36.88 mm, SE: 8.75, p = 0.001). The need for sleep supplementation was statistically significantly lower in patients with eye masks (MD: 39.79 mm, SE: 7.23, p = 0.001). There was a significant difference in melatonin levels between eye masks and the control group (p = 0.03). For urinary cortisol levels, there were significant differences between eye masks and the control group (p = 0.007), earplugs and the control group (p = 0.001), and eye masks with earplugs and the control group (p = 0.006). The mean scores for comfort, effectiveness, and ease of use were highest for the group that used eye masks (2.88, 2.94, and 3.18, respectively). As a result, all three interventions improved the sleep quality of patients. However, the interventions had different effects on the three dimensions of the VSH Sleep Scale, as well as the urinary levels of cortisol and melatonin.
