Intensive care unit interventions to promote sleep and circadian biology in reducing incident delirium: a scoping review. Thorax 2024; 79:988-997. [PMID: 38350730 DOI: 10.1136/thorax-2023-220036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Accepted: 01/26/2024] [Indexed: 02/15/2024]
Abstract
RATIONALE/OBJECTIVES Despite plausible pathophysiological mechanisms, research is needed to confirm the relationship between sleep, circadian rhythm and delirium in patients admitted to the intensive care unit (ICU). The objective of this review is to summarise existing studies promoting, in whole or in part, the normalisation of sleep and circadian biology and their impact on the incidence, prevalence, duration and/or severity of delirium in ICU. METHODS A sensitive search of electronic databases and conference proceedings was completed in March 2023. Inclusion criteria were English-language studies of any design that evaluated in-ICU non-pharmacological, pharmacological or mixed intervention strategies for promoting sleep or circadian biology and their association with delirium, as assessed at least daily. Data were extracted and independently verified. RESULTS Of 7886 citations, we included 50 articles. Commonly evaluated interventions include care bundles (n=20), regulation or administration of light therapy (n=5), eye masks and/or earplugs (n=5), one nursing care-focused intervention and pharmacological intervention (eg, melatonin and ramelteon; n=19). The association between these interventions and incident delirium or severity of delirium was mixed. As multiple interventions were incorporated in included studies of care bundles and given that there was variable reporting of compliance with individual elements, identifying which components might have an impact on delirium is challenging. CONCLUSIONS This scoping review summarises the existing literature as it relates to ICU sleep and circadian disruption (SCD) and delirium in ICU. Further studies are needed to better understand the role of ICU SCD promotion interventions in delirium mitigation.

Zhou H, Qiu Y. Retrospective Study on the Value of Intensive Care Unit Noise Reduction Management in Elderly Patients with Chronic Renal Failure in the Uremic Phase. Noise Health 2024; 26:376-382. [PMID: 39345080 DOI: 10.4103/nah.nah_70_24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2024] [Accepted: 05/07/2024] [Indexed: 10/01/2024] Open
Abstract
OBJECTIVE This study aimed to investigate the value of noise reduction management in the intensive care unit (ICU) in elderly patients with chronic renal failure (CRF) in the uremic phase. METHODS A retrospective study was conducted, including 150 elderly patients with CRF in the uremic phase, who were treated in the ICU ward at the First Affiliated Hospital of Soochow University between January 2021 and August 2023. Among them, 73 were in the control group (routine ICU management), and 77 were in the observation group (routine ICU management + ICU noise reduction management). Anxiety, depression, sleep treatment, quality of life, blood pressure, heart rate (HR), and cortisol (COR) levels were compared between the two groups at baseline and 10 days after admission to the ICU. RESULTS There was no statistical significance in the comparison of baseline data between the two groups of patients (P > 0.05). At 10 days, the sleep quality of patients in the observation group was higher than that in the control group (P < 0.05). Anxiety levels, as well as blood pressure, HR, and COR levels, were significantly lower (P < 0.05), whereas the quality of life was higher in the observation group than in the control group (P< 0.05). CONCLUSION ICU noise reduction management can effectively improve the sleep quality and quality of life of elderly patients with CRF in the uremic phase.

Sleep in the intensive and intermediate care units: Exploring related factors of delirium, benzodiazepine use and mortality. Intensive Crit Care Nurs 2024; 81:103603. [PMID: 38171236 DOI: 10.1016/j.iccn.2023.103603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 11/25/2023] [Accepted: 12/09/2023] [Indexed: 01/05/2024]
Abstract
AIM OF THE STUDY The primary purpose was to examine sleep difficulties and delirium in the Intensive and Intermediate Care Unit. Secondarily, factors impacting night-time sleep duration and quality, mortality, and the impact of benzodiazepine use on sleep outcomes were investigated. MATERIALS AND METHODS This retrospective study encompassed data from 323 intensive and intermediate care unit admissions collected in the Netherlands, spanning from November 2018 to May 2020. Sleep quality was measured using the Richards-Campbell Sleep Questionnaire. Night-time sleep duration was nurse-reported. We investigated associations of these sleep outcomes with age, sex, length-of-stay, natural daylight, disease severity, mechanical ventilation, benzodiazepine use, and delirium using Generalized Estimating Equations models. Associations with one-year post-discharge mortality were analyzed using Cox regression. RESULTS Night-time sleep duration was short (median 4.5 hours) and sleep quality poor (mean score 4.9/10). Benzodiazepine use was common (24 % of included nights) and was negatively associated with night-time sleep duration and quality (B = -0.558 and -0.533, p <.001). Delirium and overnight transfers were negatively associated with sleep quality (B = -0.716 and -1.831, p <.05). The day-to-night sleep ratio was higher in the three days before delirium onset than in non-delirious individuals (p <.05). Age, disease severity and female sex were associated with increased one-year mortality. Sleep quality was negatively, but not-significantly, associated with mortality (p =.070). CONCLUSIONS Night-time sleep in the critical care environment has a short duration and poor quality. Benzodiazepine use was not associated with improved sleep. Sleep patterns change ahead of delirium onset. IMPLICATIONS FOR CLINICAL PRACTICE Consistent sleep monitoring should be part of routine nursing practice, using a validated instrument like the Richards-Campbell Sleep Questionnaire. Given the lack of proven efficacy of benzodiazepines in promoting sleep in critical care settings, it is vital to develop more effective sleep treatments that include non-benzodiazepine medication and sleep hygiene strategies.

Abstract
PURPOSE Caregivers must cope with a poor sleep environment when caring for someone admitted to the hospital. The aim was to study the environmental factors associated with a sleep disruption pattern in caregivers during hospitalization and to test their association with caregivers' insomnia symptoms. DESIGN This was a cross-sectional study. METHODS One hundred twenty-three caregivers completed the study. The effect of environmental stimuli on sleep disruption was measured on a scale from 1 to 10 (1 = no disruption, 10 = significant disruption). Type of room (single vs shared), insomnia symptoms, anxiety and depression, and patients' dependence (Barthel Index) were assessed as well. Caregiver and patient characteristics as well as identified hospital disruptors were compared with Student t test, χ2 test, and Fisher exact test according to the caregivers' type of room. A linear regression model using main caregiver and patient sociodemographic variables, questionnaires, and the sum of all hospital disruptors determined the factors associated with caregivers' insomnia symptoms. RESULTS Of the caregivers and their care recipients, 51.2% shared a room with 1 to 2 other patients. Higher self-reported levels of sleep disruption due to environmental stimuli were found in shared rooms when compared with single rooms (eg, nursing care, noise, and light) (P < .05). Hospital sleep disruptors (adjusted regression coefficient, 0.15; 95% confidence interval, 0.06-0.24) and caregiver anxiety (adjusted regression coefficient, 0.57; 95% confidence interval, 0.33-0.81) were predictors for insomnia (P < .01). However, caregivers' type of room was not associated with insomnia severity symptoms (P > .05). CONCLUSIONS Interventions are urgent to implement, such as relieving caregivers from patient needs during the night, providing them with single rooms, and conducting multiple nursing tasks in 1 visit to minimize night hospital noise.

Abstract
Critical illness and stays in the Intensive Care Unit (ICU) have significant impact on sleep. Poor sleep is common in this setting, can persist beyond acute critical illness, and is associated with increased morbidity and mortality. In the past 5 years, intensive care clinical practice guidelines have directed more focus on sleep and circadian disruption, spurring new initiatives to study and improve sleep complications in the critically ill. The global SARS-COV-2 (COVID-19) pandemic and dramatic spikes in patients requiring ICU level care also brought augmented levels of sleep disruption, the understanding of which continues to evolve. This review aims to summarize existing literature on sleep and critical illness and briefly discuss future directions in the field.

Abstract
During acute hospitalization, many caregivers decide to stay at the care recipient's bedside over the course of several days or months, coping with a stressful situation and a poor sleeping environment. Our objective was to characterize caregiver sleep-wake cycles during care recipient hospital admission and test the association between sleep location (home versus hospital) and caregiver sleep. Eighty-six informal caregivers (78.8% female; age 55.47 ± 12.43 years) were recruited. For seven consecutive days, caregivers wore actigraphy devices and filled a sleep diary indicating whether they had slept at the hospital or at home. Caregiver insomnia symptoms, anxiety, and depression along with patient dependence were also assessed. Nighttime total sleep time, wake after sleep onset, sleep efficiency, sleep latency, and fragmentation index were described. Mixed-model analyses were used to evaluate the effect of the overnight location (home versus hospital) on caregiver sleep quality. In total, 38.4% of caregivers exhibited poor objective sleep efficiencies (< 80%), and 43% of caregivers reported having moderate to severe insomnia symptoms. Caregivers mostly slept at the hospital (n = 53), but some slept at home (n = 14) or between both locations (n = 19). Mixed-model analyses using actigraphy showed that caregivers had significantly better sleep quality when resting at home regarding wake after sleep onset, fragmentation index, and sleep efficiency (p < .05). Caregivers experienced poor sleep quality during care recipients' hospitalization, specifically when sleeping at the hospital versus sleeping at home. Healthcare workers should ensure caregivers' well-being and strongly encourage caregivers to rest at home whenever possible.

Abstract
Caregivers experience high levels of emotional stress and must cope with several clinical and hospital-related environmental factors that seriously impact their night’s rest. The purpose of this study was to establish the prevalence of insomnia symptoms in a sample of caregivers of adult hospitalized patients and to examine the relationships between insomnia symptoms and patient and caregiver-associated factors. A total of 152 caregivers were enrolled from the two main hospitals in Granada, Spain. Sociodemographic, economic, and care-related data were collected. Insomnia symptoms, burden, anxiety and depression, social support, and resilience were assessed. Information on patients’ hospital admission, dependence, and neuropsychiatric symptoms was also obtained. Most caregivers were middle-aged women caring for their spouses. Self-reported insomnia prevalence was set at 45.4%. Comparison analyses between caregivers suffering from insomnia symptoms and non-insomniacs showed significantly higher burden, anxiety and depression and patients’ neuropsychiatric symptoms (p < 0.05) and lower resilience and social support in the former (p < 0.01). A regression analysis showed that anxiety (ORa = 1.15; p < 0.05) and higher caregiver education level (ORa = 5.50; p < 0.05) were factors significantly associated with insomnia symptoms. Patients’ neuropsychiatric symptoms showed a trend toward statistical significance as well (ORa = 1.09; p = 0.06). There is an acute need to address, prevent and treat insomnia problems in caregivers.

Abstract
PURPOSE OF REVIEW Sleep is particularly important for critically ill patients. Here, we review the latest evidence on how sleep and circadian disruption in the intensive care unit (ICU) affects physiology and clinical outcomes, as well as the most recent advances in sleep and circadian rhythm promoting interventions including therapeutics. RECENT FINDINGS On a molecular level, clock genes dysrhythmia and altered immunity are clearly linked, particularly in sepsis. Melatonin may also be associated with insulin sensitivity in ICU patients. Clinically, changes in sleep architecture are associated with delirium, and sleep-promoting interventions in the form of multifaceted care bundles may reduce its incidence. Regarding medications, one recent randomized controlled trial (RCT) on melatonin showed no difference in sleep quality or incidence of delirium. SUMMARY Further investigation is needed to establish the clinical relevance of sleep and circadian disruption in the ICU. For interventions, standardized protocols of sleep promotion bundles require validation by larger multicenter trials. Administratively, such protocols should be individualized to both organizational and independent patient needs. Incorporating pharmacotherapy such as melatonin and nocturnal dexmedetomidine requires further evaluation in large RCTs.
