Abstract
BACKGROUND High-quality sleep is important for optimal patient recovery. Sleep deprivation during hospitalization may lead to poor patient outcomes. OBJECTIVE To examine whether implementation of a sleep promotion bundle in the intensive care unit affects rates of delirium and agitation, restraint use, and length of stay. METHODS An evidence-based sleep promotion bundle was developed and implemented in 2 intensive care units in a 1025-bed level I trauma teaching hospital. Deidentified data from the electronic health record were obtained for patients hospitalized before and during the intervention. Data included scores on the Confusion Assessment Method for the Intensive Care Unit, Richmond Agitation-Sedation Scale, and Glasgow Coma Scale; restraint use; and hospital and intensive care unit length of stay. RESULTS A total of 137 patients during the preintervention period and 149 patients during the intervention period were hospitalized in the intensive care units and met inclusion criteria. A 9-percentage-point decrease in the incidence of delirium from before to during the intervention was found, although it was not statistically significant (P = .07). Significant reductions were found in both intensive care unit (P = .04) and hospital (P = .03) length of stay. A significant decrease was found in Richmond Agitation-Sedation Scale high scores for patients requiring mechanical ventilation (P = .03). No significant differences were found in Richmond Agitation-Sedation Scale low scores, Glasgow Coma Scale scores, or restraint use. CONCLUSIONS Critical care nurses are in an optimal position to implement evidence-based sleep promotion measures. Further research on sleep promotion bundles is needed.

Intensive care unit interventions to promote sleep and circadian biology in reducing incident delirium: a scoping review. Thorax 2024:thorax-2023-220036.

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.

Abstract
Background: The Society of Critical Care Medicine Clinical Practice Guidelines for Management of Pain, Agitation, Delirium, Immobility, and Sleep recommend protocolized non-pharmacologic sleep improvement. Pharmacologic interventions are frequently initiated to promote sleep but the evidence supporting these strategies remains controversial. Purpose: To systematically search and synthesize evidence evaluating pharmacologic sleep promotion modalities in critically ill adults. Methods: A rapid systematic review protocol was used to search Medline, Cochrane Library, and Embase for reports published through October 2022. We included randomized controlled trials (RCTs) and before-and-after cohort studies evaluating pharmacologic modalities intended to improve sleep in adult intensive care unit (ICU) patients. Sleep-related endpoints were the primary outcome of interest. Study and patient characteristics and relevant safety and non-sleep outcome data were also collected. The Cochrane Collaboration Risk of Bias or Risk of Bias in Non-Randomized Studies of Interventions were used to assess the risk of bias for all included studies. Results: Sixteen studies (75% RCTs) enrolling 2573 patients were included; 1207 patients were allocated to the pharmacologic sleep intervention. Most studies utilized dexmedetomidine (7/16; total n = 505 patients) or a melatonin agonist (6/16; total n = 592 patients). Only half of the studies incorporated a sleep promotion protocol as standard of care. Most (11/16, 68.8%) studies demonstrated a significant improvement in ≥1 sleep endpoint (n = 5 dexmedetomidine, n = 3 melatonin agonists, n = 2 propofol/benzodiazepines). Risk of bias was generally low for RCTs and moderate-severe for cohort studies. Conclusions: Dexmedetomidine and melatonin agonists are the most studied pharmacologic sleep promotion modalities, but current evidence does not support their routine administration in the ICU to improve sleep. Future RCTs evaluating pharmacologic modalities for ICU sleep should consider patients' baseline and ICU risks for disrupted sleep, incorporate a non-pharmacologic sleep improvement protocol, and evaluate the effect of these medication interventions on circadian rhythm, physiologic sleep, patient-perceived sleep quality, and delirium.

Abstract
STUDY OBJECTIVES Sleep is crucial for healing but often impaired in the pediatric intensive care unit due to environmental disruptions. Caregivers and bedside nursing staff are often most aware of these factors and the impact on patient sleep, but studies have not yet compared their perceptions. METHODS Caregivers and bedside nursing staff of pediatric patients staying a second night in the pediatric intensive care unit were asked to complete a survey regarding environmental factors (ie, temperature, light, sound, nursing staff room entries), sleep quality, and sleep quantity (ie, sleep duration, number of naps) of the pediatric patient. Caregivers were asked similar questions about their child's sleep at home. RESULTS The caregivers and nursing staff of 31 pediatric patients participated in this pilot study. There was no significant difference between caregiver and nursing staff ratings of sleep quality, sleep duration, number of naps, room temperature, sound, or light (P > .05 for all). Nursing staff did report significantly more room entries than caregivers (P = .01). Compared to sleep at home, caregivers reported sleep in the hospital to be of lower quality (P = .009) with more frequent room entries (P = .01). CONCLUSIONS Caregivers rate their child's sleep in the pediatric intensive care unit as lower quality than sleep at home. Caregivers and bedside nursing staff largely agree about pediatric patient sleep quality and quantity as well as environmental factors. This agreement may facilitate further research and interventions at improving sleep in the pediatric intensive care unit. CITATION Witte MA, Lloyd RM, McGree M, Kawai Y.

Abstract
The odds ratio product (ORP) is a continuous metric of sleep depth that ranges from 0 (very deep sleep) to 2. 5 (full wakefulness). Its advantage over the conventional method recommended by AASM is that it discloses different levels of stage wake (sleep propensity) and different sleep depths within the same sleep stage. As such, it can be used to identify differences in sleep depth between subjects, and in the same subjects under different circumstances, when differences are not discernible by conventional staging. It also identifies different sleep depths within stage rapid-eye-movement sleep, with possible implications to disorders during this stage. Epoch-by-epoch ORP can be displayed graphically across the night or as average values in conventional sleep stages. In addition, ORP can be reported as % of recording time in specific ORP ranges (e.g., deciles of the total ORP range) where it produces distinct distribution patterns (ORP-architecture) that have been associated with different clinical disorders and outcomes. These patterns offer unique research opportunities to identify different mechanisms and potential therapy for various sleep complaints and disorders. In this review I will discuss how ORP is measured, its validation, differences from delta power, and the various phenotypes, and their postulated mechanisms, identified by ORP architecture and the opportunities for research to advance management of sleep-disordered breathing, insomnia and idiopathic hypersomnia.

Abstract
Background Delirium is common in critically ill patients and associated with longer hospital stays, increased morbidity and higher healthcare costs. Non-pharmacological interventions have been advocated for delirium management, however there is little evidence evaluating feasibility and acceptability of physical interventions administered in the evening. The aim of this study was to conduct a feasibility trial of evening mobilisation to prevent and treat delirium in patients admitted to intensive care. Methods In this mixed-methods, randomised controlled feasibility trial we recruited participants from intensive care units at two university hospitals in the United Kingdom. Eligible participants who were able to respond to verbal stimulus (Richmond agitation and sedation scale ≥3) and expected to stay in intensive care for at least 24 h were randomly assigned (1:1) to receive usual care or usual care plus evening mobilisation. The evening mobilisation was delivered between 19:00 and 21:00, for up to seven consecutive evenings or ICU discharge, whichever was sooner. All outcome assessments were completed by a team member blinded to randomisation and group allocation. Primary objective was to assess feasibility and acceptability of evening mobilisation. Primary feasibility outcomes were recruitment, consent and retention rates, and intervention fidelity. Intervention acceptability was evaluated through semi-structured interviews of participants and staff. Secondary outcomes included prevalence in incidence and duration of delirium, measured using the Confusion Assessment Method for ICU. This trial is registered at ClinicalTrials.gov, NCT05401461. Findings Between July 16th, 2022, and October 31st, 2022, 58 eligible patients (29 usual care; 29 usual care plus evening mobilisation) were enrolled. We demonstrated the feasibility and acceptability of both the trial design and evening mobilisation intervention. Consent and retention rates over three months were 88% (58/66) and 90% (52/58) respectively, with qualitative analysis demonstrating good acceptability reported by both participants and staff. Secondary outcomes for the evening intervention group compared with the control group were: delirium incidence 5/26 (19%; 95% CI: 6-39%) vs 8/28 (29%; 95% CI: 13-49%) and mean delirium duration 2 days (SD 0.7) vs 4.25 days (SD 2.0). Interpretation Results of this trial will inform the development of a definitive full-scale randomised controlled trial investigating the effects of evening mobilisation to treat delirium and improve health-related outcomes.

Abstract
Intensive care units (ICUs) may disrupt sleep. Quantitative ICU studies of concurrent and continuous sound and light levels and timings remain sparse in part due to the lack of ICU equipment that monitors sound and light. Here, we describe sound and light levels across three adult ICUs in a large urban United States tertiary care hospital using a novel sensor. The novel sound and light sensor is composed of a Gravity Sound Level Meter for sound level measurements and an Adafruit TSL2561 digital luminosity sensor for light levels. Sound and light levels were continuously monitored in the room of 136 patients (mean age = 67.0 (8.7) years, 44.9% female) enrolled in the Investigation of Sleep in the Intensive Care Unit study (ICU-SLEEP; Clinicaltrials.gov: #NCT03355053), at the Massachusetts General Hospital. The hours of available sound and light data ranged from 24.0 to 72.2 hours. Average sound and light levels oscillated throughout the day and night. On average, the loudest hour was 17:00 and the quietest hour was 02:00. Average light levels were brightest at 09:00 and dimmest at 04:00. For all participants, average nightly sound levels exceeded the WHO guideline of < 35 decibels. Similarly, mean nightly light levels varied across participants (minimum: 1.00 lux, maximum: 577.05 lux). Sound and light events were more frequent between 08:00 and 20:00 than between 20:00 and 08:00 and were largely similar on weekdays and weekend days. Peaks in distinct alarm frequencies (Alarm 1) occurred at 01:00, 06:00, and at 20:00. Alarms at other frequencies (Alarm 2) were relatively consistent throughout the day and night, with a small peak at 20:00. In conclusion, we present a sound and light data collection method and results from a cohort of critically ill patients, demonstrating excess sound and light levels across multiple ICUs in a large tertiary care hospital in the United States.

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
INTRODUCTION Delirium is common in critically ill patients and is associated with longer hospital stays, increased mortality and higher healthcare costs. A number of risk factors have been identified for the development of delirium in intensive care, two of which are sleep disturbance and immobilisation. Non-pharmacological interventions for the management of intensive care unit (ICU) delirium have been advocated, including sleep protocols and early mobilisation. However, there is a little published evidence evaluating the feasibility and acceptability of evening mobilisation. METHODS AND ANALYSIS Mobilisation in the EveNing to TreAt deLirium (MENTAL) is a two-centre, mixed-methods feasibility randomised controlled trial (RCT). Sixty patients will be recruited from ICUs at two acute NHS trusts and randomised on a 1:1 basis to receive additional evening mobilisation, delivered between 19:00 and 21:00, or standard care. The underpinning hypothesis is that the physical exertion associated with evening mobilisation will promote better sleep, subsequently having the potential to reduce delirium incidence. The primary objective is to assess the feasibility and acceptability of a future, multicentre RCT. The primary outcome measures, which will determine feasibility, are recruitment and retention rates, and intervention fidelity. Acceptability of the intervention will be evaluated through semi-structured interviews of participants and staff.

EUROPEAN JOURNAL OF CARDIO-THORACIC SURGERY : OFFICIAL JOURNAL OF THE EUROPEAN ASSOCIATION FOR CARDIO-THORACIC SURGERY 2022; 63:6965024. [PMID: 36579859 DOI: 10.1093/ejcts/ezac573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Revised: 12/08/2022] [Accepted: 12/28/2022] [Indexed: 12/30/2022]
Abstract
OBJECTIVES Postoperative delirium is a common severe complication in patients in the intensive care unit after cardiac surgery. We developed a two-stage prediction model and quantified the risk of developing postoperative delirium to assist in early prevention before and after surgery. METHODS We conducted a prospective cohort study and consecutively recruited adult patients after cardiac surgery. The Confusion Assessment Method for patients in the intensive care unit was used to diagnose delirium 5 days postoperatively. The stage I model was constructed using patient demographics, health conditions and laboratory results obtained preoperatively, whereas the stage II model was built on both pre- and postoperative predictors. The model was validated internally using the bootstrap method and externally using data from an external cohort. RESULTS The two-stage model was developed with 654 patients and was externally validated with 214 patients undergoing cardiac surgery. The stage I model contained 6 predictors, whereas the stage II model included 10 predictors. The stage I model had an area under the receiver operating characteristic curve of 0.76 (95% confidence interval: 0.68-0.81), and the stage II model's area under the receiver operating characteristic curve increased to 0.85 [95% confidence interval (CI): 0.81-0.89]. The external validation resulted in an area under the curve of 0.76 (95% CI: 0.67-0.86) for the stage I model and 0.78 (95% CI: 0.69-0.86) for the stage II model. CONCLUSIONS The two-stage model assisted medical staff in identifying patients at high risk for postoperative delirium before and 24 h after cardiac surgery. This model showed good discriminative power and predictive accuracy and can be easily accessed in clinical settings. TRIAL REGISTRATION The study was registered with the US National Institutes of Health ClinicalTrials.gov (NCT03704324; registered 11 October 2018).

The potential link between obstructive sleep apnea and postoperative neurocognitive disorders: current knowledge and possible mechanisms. Can J Anaesth 2022; 69:1272-1287. [PMID: 35982354 PMCID: PMC9924301 DOI: 10.1007/s12630-022-02302-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Revised: 04/08/2022] [Accepted: 04/08/2022] [Indexed: 01/12/2023] Open
Abstract
PURPOSE This narrative review examines the current evidence on whether obstructive sleep apnea (OSA) is associated with postoperative delirium (POD) and postoperative cognitive dysfunction (POCD). The mechanisms that could predispose OSA patients to these disorders are also explored. SOURCE Relevant literature was identified by searching for pertinent terms in Medline®, Pubmed, ScopusTM, and Google scholar databases. Case reports, abstracts, review articles, original research articles, and meta-analyses were reviewed. The bibliographies of retrieved sources were also searched to identify relevant papers. PRINCIPAL FINDINGS Seven studies have investigated the association between OSA and POD, with mixed results. No studies have examined the potential link between OSA and POCD. If these relationships exist, they could be mediated by several mechanisms, including increased neuroinflammation, blood-brain barrier breakdown, cerebrovascular disease, Alzheimer's disease neuropathology, disrupted cerebral autoregulation, sleep disruption, sympathovagal imbalance, and/or disrupted brain bioenergetics. CONCLUSION There is very limited evidence that OSA plays a role in postoperative neurocognitive disorders because few studies have been conducted in the perioperative setting. Additional perioperative prospective observational cohort studies and randomized controlled trials of sleep apnea treatment are needed. These investigations should also assess potential underlying mechanisms that could predispose patients with OSA to postoperative neurocognitive disorders. This review highlights the need for more research to improve postoperative neurocognitive outcomes for patients with OSA.

Effects of nonpharmacological interventions on sleep improvement and delirium prevention in critically ill patients: A systematic review and meta-analysis. Aust Crit Care 2022:S1036-7314(22)00062-5. [PMID: 35718628 DOI: 10.1016/j.aucc.2022.04.006] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Revised: 04/01/2022] [Accepted: 04/01/2022] [Indexed: 11/15/2022] Open
Abstract
OBJECTIVE Sleep disturbance and delirium are common problems experienced by critically ill patients in the intensive care unit (ICU). These interrelated issues increase the length of stay in the ICU but might also negatively affect long-term health outcomes. The objective of this study was to identify the nonpharmacological interventions provided to improve sleep or prevent delirium in ICU patients or both and integrate their effect sizes. REVIEW METHODS This study was a registered systematic review and meta-analysis. We searched MEDLINE, CINAHL, EMBASE, Web of Science, and Cochrane Library from their inception until December 2021. We included randomised controlled trials and nonrandomised controlled trials-(RCT) that provided nonpharmacological interventions and reported sleep or delirium as outcome variables. Studies not published in English or whose full text was not available were excluded. The quality of the evidence was assessed with version 2 of the Cochrane risk-of-bias tool for RCTs and the Risk Of Bias In Non-randomised Studies of Interventions (ROBINS-I). RESULTS The systematic review included 118 studies, and the meta-analysis included 100 studies. Overall nonpharmacological interventions had significant effects on subjective sleep quality (standardised mean difference = 0.30, 95% confidence interval [CI] = 0.05 to 0.56), delirium incidence (odds ratio = 0.62, 95% CI = 0.53 to 0.73), and delirium duration (standardised mean difference = -0.68, 95% CI = -0.93 to -0.43). In individual interventions, aromatherapy, music, and massage effectively improved sleep. Exercise, family participation, information giving, cognitive stimulation, bright light therapy, architectural intervention, and bundles/protocols effectively reduced delirium. Light/noise blocking was the only intervention that ensured both sleep improvement and delirium prevention. CONCLUSIONS Our results suggest nonpharmacological interventions improve sleep and prevent delirium in ICU patients. We recommend that ICU nurses use nonpharmacological interventions that promote person-environment compatibility in their clinical practice. The results of our review can guide nurses in adopting interventions related to sleep and delirium. PROSPERO REFERENCE NUMBER CRD42021230815.

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
OBJECTIVE To transform an inpatient orthopaedic unit into an age-friendly unit for geriatric fracture center (GFC) patients. DESIGN Pragmatic dissemination study of a continuous quality improvement intervention with episodic data review. SETTING Large quaternary care university hospital with no on-site geriatrics program and no dedicated geriatric inpatient unit. PARTICIPANTS Individuals 60 years of age and older with fragility fracture of the native proximal femur hospitalized from July 2017 to June 2020. INTERVENTION A hospital medicine-orthopaedics comanagement model for a GFC was developed using processes, tools, and education provided by the American Geriatrics Society's AGS CoCare: Ortho program to support the age-friendly 4Ms principles: mentation, mobility, medications, and what matters. Delirium reduction strategies included minimizing sleep interruption through changes in blood draw times, order sets for pain management, and nursing education. Mobility specialists were incorporated to improve early mobilization on the orthopaedic unit. MAIN OUTCOME MEASUREMENTS Frequency of weight-bearing on postoperative day 1 and frequency of delirium among GFC patients on the orthopaedic unit were compared with those among concurrent GFC patients on other units. RESULTS Frequency of delirium was 26% among patients on the orthopaedic unit versus 35% among those on other units (P = 0.055). Frequency of weight-bearing on post-operative day 1 was 84% among patients on the orthopaedic unit versus 72% among those on other units (P = 0.003). CONCLUSIONS AGS CoCare: Ortho is an effective dissemination program for establishing a hospital medicine-orthopaedics comanagement program and making an orthopaedic unit age-friendly in a hospital without onsite geriatricians or a dedicated geriatrics unit. LEVEL OF EVIDENCE Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Objective To evaluate the effect of intensive care unit (ICU) visit on the incidence of delirium, delirium subtype, and anxiety level in ICU patients. Methods Trained psychiatrists and nurses evaluated ICU patients for delirium, delirium subtypes, and anxiety. Propensity score matching (PSM) was used to retrospectively analyze the data. Then, we compared the differences in the incidence of delirium, delirium subtypes, and anxiety level before and after the ICU visit ban. Logistic regression was conducted to identify the risk factors for delirium subtypes and high anxiety levels. Results After PSM, there was no statistically significant difference in the incidence of delirium between the non-visiting and restrictive visiting groups (non-visiting 27.4% versus restrictive visiting 30.9%, p = 0.162). The proportion of hyperactive and mixed subtypes was higher in the non-visiting than in the restrictive visiting group (non-visiting 35.3 and 30.1% versus restrictive visiting 27.7 and 20.1%, p = 0.002). The anxiety level was higher in the non-visiting than in the restrictive visiting group (state-trait anxiety inventory score: non-visiting 53.46 ± 4.58 versus restrictive visiting 52.22 ± 6.50, p = 0.009). Patients who stayed in the ICU during the visit ban were more likely to have hyperactive (p = 0.005) and mixed subtype (p = 0.001) than those who did not. Moreover, patients who stayed in the ICU during the visit ban were more likely to experience high anxiety levels than those who did not (p < 0.001). Conclusion Prohibition of ICU visits during COVID-19 pandemic did not affect the incidence of delirium during COVID-19 but could change the delirium subtype and raise anxiety level. Moreover, visiting prohibition was a risk factor for non-hypoactive delirium subtype and high anxiety levels. Therefore, ICU visits are important in dealing with delirium subtypes and anxiety in ICU patients.

Abstract
BACKGROUND Despite data supporting the reduction of interactions with patients during nighttime, bed bathing is sometimes performed within this period in sedated patients unable to manage their own hygiene care. OBJECTIVES To compare patient physiologic variables and adverse effect incidence between night and day bed baths. METHODS This was a single-center prospective observational study in a 12-bed intensive care unit during 2 months. Night period was defined to run from 10 pm to 6 am. Night bed baths were provided to sedated ventilated patients whatever their sedation, if their Richmond Agitation Sedation Scale score was -2 or deeper. Bed bath-induced changes in physiological variables, treatments, and related unscheduled events were registered during both night and day bed baths. RESULTS Twenty-one patients (aged 62.9 [52.5-73.2] years, 14 male patients) were included. We registered 97 night bed baths and 95 day bed baths. Heart rate increased only after day bed baths (85 beats/min [bpm] [69-97 bpm] vs 88 bpm [73-98 bpm], P = .02). Increase in Richmond Agitation Sedation Scale score occurred, respectively, during 13 (13.4%) and 8 (8.4%) night and day bed baths, without significant differences. Body temperature significantly decreased during both night and day bed baths (respectively, 37°C [36.6°C-37.4°C] vs 36.6°C [36.2°C-37.2°C], P < .0001; and 36.9°C [36.5°C-37.2°C] vs 36.7°C [36.2°C-37.2°C], P = .0006). Overall, unscheduled events, whether physiologic changes, pain, or calling a physician in rescue occurred in 97 procedures (50.5%), irrespective of their timing (night vs day, respectively 53% [54.6%] vs 44% [46.3%], P = .31). DISCUSSION Although unscheduled events occurred in half of bed baths, differences evidenced between nighttime and daytime bed baths were scarce. The appropriateness of nighttime bed bathing remains questionable.

Abstract
BACKGROUND Environmental factors such as loud sounds and bright lights in intensive care units can cause sleep disorders and delirium. AIM The present study aims to investigate the effects of the overnight use of earplugs and eye masks by intensive care patients on their sleep quality and the degree of delirium. STUDY DESIGN This randomized controlled experimental study was conducted on the patients admitted to a coronary intensive care unit. METHODS The patients in the experimental group used earplugs and eye masks during the night, while those in the control group received only routine care. Data were collected using an information form, the Richards-Campbell sleep questionnaire (RCSQ), and the intensive care delirium screening checklist (ICDSC). RESULTS The study included a total of 84 patients, 42 in the experimental group and 42 in the control group. The baseline average score of the patients in the experiment group on the RCSQ was 40.11 ± 16.55, with a Time 1 average score of 64.09 ± 14.07 and a Time 2 average score of 72.07 ± 11.75; their baseline average score on the ICDSC was 0.47 ± 0.50, with a Time 1 average score of 0.33 ± 065 and a Time 2 average score of 0.19 ± 039. The baseline average score of the patients in the control group on the RCSQ was 44.07 ± 7.30, with a Time 1 average score of 46.97 ± 9.22 and a Time 2 average score of 47.04 ± 11.53; the baseline average score of the control group on the ICDSC was 0.42 ± 0.50, with a Time 1 average score of 0.50 ± 0.70 and a Time 2 average score of 0.57 ± 0.66. A statistically significant difference was found between the Time 1 and Time 2 average scores of the experimental and control groups on the RCSQ and between the Time 2 average scores of the experimental and control groups on the ICDSC (U = 198.00, P < .001; U = 70.000, P < .001; U = 614.000, P = ·004 respectively). CONCLUSIONS The earplugs and eye masks used by the intensive care patients overnight were associated with an increase in sleep quality and a decrease in the degree of delirium. RELEVANCE TO CLINICAL PRACTICE The use of earplugs and eye masks is recommended for intensive care units in supporting sleep quality and preventing delirium.

Abstract
BACKGROUND Evidence suggests that poor sleep increases risk of delirium. Because delirium is associated with poor outcomes, institutions have developed protocols to improve sleep in critically ill patients. OBJECTIVE To assess the impact of implementing a multicomponent sleep protocol. METHODS In this prospective, preimplementation and postimplementation evaluation, adult patients admitted to the medical intensive care unit (ICU) over 42 days were included. Outcomes evaluated included median delirium-free days, median Richards-Campbell Sleep Questionnaire (RCSQ) score, median optimal sleep nights, duration of mechanical ventilation (MV), ICU and hospital length of stay (LOS), and in-hospital mortality. RESULTS The preimplementation group included 78 patients and postimplementation group, 84 patients. There was no difference in median delirium-free days (1 day [interquartile range, IQR, = 0-2.5] vs 1 day [IQR = 0-2]; P = 0.48), median RCSQ score (59.4 [IQR = 43.2-71.6] vs 61.2 [IQR = 49.9-75.5]; P = 0.20), median optimal sleep nights (1 night [IQR = 0-2] vs 1 night [IQR = 0-2]; P = 0.95), and in-hospital mortality (16.7% vs 17.9%, P = 1.00). Duration of MV (8 days [IQR = 4-10] vs 4 days [IQR = 2-7]; P = 0.03) and hospital LOS (13 days [IQR = 7-22.3] vs 8 days [IQR = 6-17]; P = 0.05) were shorter in the postimplementation group, but both were similar between groups after adjusting for age and severity of illness. CONCLUSIONS AND RELEVANCE This report demonstrates that implementation of a multicomponent sleep protocol in everyday ICU care is feasible, but limitations exist when evaluating impact on measurable outcomes. Additional evaluations are needed to identify the most meaningful interventions and best practices for quantifying impact on patient outcomes.

Abstract
BACKGROUND Sleep disruptions in the intensive care unit (ICU) may lead to complications such as delirium. There is limited evidence addressing how sleep aid use before and during ICU admission affects outcomes. OBJECTIVE The purpose of this study is to evaluate the impact of prior-to-admission sleep aid prescribing practices in the ICU on delirium and sleep outcomes. METHODS A retrospective review was conducted of adult patients admitted to any ICU from January to June 2018 receiving a sleep aid prior to admission. Patients were categorized based on sleep aid continuation, discontinuation, or alteration during the ICU admission. The primary end point was the incidence of delirium. Secondary end points included the incidence of sleep-wake cycle disturbances, delirium scores, and ICU length of stay. RESULTS A total of 291 patients were included with 109 in the continued group, 121 in the discontinued group, and 61 in the altered group. There was a similar incidence of delirium at 24 hours (P = 0.71), 48 hours (P = 0.60), 72 hours (P = 0.25), and 5 days (P = 0.48) after ICU admission. There was also no statistical difference in sleep-wake cycle disturbances or delirium scores at any time point. ICU length of stay was similar between the groups. CONCLUSION AND RELEVANCE The incidence of delirium and sleep-wake cycle disturbances was not affected by differences in prior-to-admission sleep aid prescribing patterns during ICU admission.

Fazlollah A, Babatabar Darzi H, Heidaranlu E, Moradian ST. The effect of foot reflexology massage on delirium and sleep quality following cardiac surgery: A randomized clinical trial. Complement Ther Med 2021; 60:102738. [PMID: 34029674 DOI: 10.1016/j.ctim.2021.102738] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 05/08/2021] [Accepted: 05/11/2021] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Delirium is the most common neurologic disorder after cardiac surgery and affects both short and long-term outcomes. This study was conducted to evaluate the effect of foot reflexology massage on the incidence of delirium and sleep quality in patients undergoing cardiac surgery. METHODS In this randomized clinical trial, 60 patients who were candidates for CABG surgery were randomly assigned into two equal groups (n = 30); intervention and control groups. In the intervention group, foot reflexology massage was done on each foot for 15 min, for two consecutive days. Delirium observation screening scale, the Richard Campbell sleep questionnaire (RSCQ), and pain intensity using VAS were compared. RESULTS in the second postoperative day, delirium was observed in 8 (26.7 %) and 7 (23.3 %) of patients in the intervention and control groups, respectively (p > 0.05). The measured odds ratio for the effect of massage on delirium is 0.83 (95 %CI 0.71-2.69, p = 0.76). The difference in RSCQ scores was not significant between groups of intervention and control (68.32 ± 10.41 VS. 62.80 ± 11.86, P = 0.06). The pain intensity was lower in the intervention group (P < 0.001). CONCLUSION Foot reflexology was not effective in reducing delirium and improving the sleep quality, but the pain intensity was decreased. It seems that the precise pathology and predicting model of delirium should be identified, and appropriate interventions should be planned accordingly.

Nurs Crit Care 2021; 27:519-527. [PMID: 33946128 DOI: 10.1111/nicc.12638] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 04/08/2021] [Accepted: 04/10/2021] [Indexed: 12/22/2022]
Abstract
BACKGROUND Delirium is a common complication in patients in Intensive Care Units (ICU). Interventions such as mobilization are effective in the prevention and treatment of delirium, although this is usually completed during the daytime. AIM The aim of this study was to assess the feasibility of mobilization in the evening to prevent and treat ICU patients from delirium by an additional mobility team over 2 weeks. METHODS The design was a pilot, multi-centre, randomized, controlled trial in four mixed ICUs over a period of 2 weeks. The mobility team consisted of trained nurses and physiotherapists. Patients in the intervention group were mobilized onto the edge of the bed or more between 21.00 and 23.00. Patients in the control group received usual care. The primary outcome parameter was the feasibility of the study, measured as recruitment rate, delivery rate, and safety. Secondary outcomes were duration and incidence of delirium, mortality, duration of mechanical ventilation (MV), and hospital length of stay for 28 days follow-up, and power calculation for a full trial. RESULTS Out of 185 patients present in the ICUs, 28.6% (n = 53) were eligible and could be recruited, of which 24.9% (n = 46, Intervention = 26, Control = 20) were included in the final analysis. In the intervention group, mobilization could be delivered in 75% (n = 54) of 72 possible occasions; mobilization-related safety events appeared in 16.7% (n = 9) without serious consequences. Secondary parameters were similar, with less delirium in the intervention group albeit not significant. With an association of Cramer's V = 0.237, a complete study reaching statistical significance would require at least 140 patients, last 6 weeks, and cost >30 000 €. CONCLUSIONS In a mixed ICU population, mobilization in the evening was feasible in one-quarter of patients with a low rate of safety events. Future trials seem to be feasible and worth conducting.

Abstract
Sleep in intensive care is hampered due to many factors; the clinical environment itself exacerbates sleep disturbance. Research suggests that interventions aimed at improving sleep quality have produced positive effects in reducing incidences and duration of delirium. Sleep disturbance is well documented among intensive care patients; however, its prognostic impact is not fully understood. Delirium, disproportionally prevalent among intensive care patients, has significant prognostic factors related to patient outcomes, in which sleep disturbance often is present. The relationship between sleep disturbance and delirium is complex, sharing commonalities in relation to neurobiological and neurohormonal alterations, which may contribute to a bidirectional relationship.

Abstract
Background Sleep disorders, the serious challenges faced by the intensive care unit (ICU) patients are important issues that need urgent attention. Despite some efforts to reduce sleep disorders with common risk-factor controlling, unidentified risk factors remain. Objectives This study aimed to develop and validate a risk prediction model for sleep disorders in ICU adults. Methods Data were retrieved from the MIMIC-III database. Matching analysis was used to match the patients with and without sleep disorders. A nomogram was developed based on the logistic regression, which was used to identify risk factors for sleep disorders. The calibration and discrimination of the nomogram were evaluated with the 1000 bootstrap resampling and receiver operating characteristic curve (ROC). Besides, the decision curve analysis (DCA) was applied to evaluate the clinical utility of the prediction model. Results 2,082 patients were included in the analysis, 80% of whom (n = 1,666) and the remaining 20% (n = 416) were divided into the training and validation sets. After the multivariate analysis, hemoglobin, diastolic blood pressure, respiratory rate, cardiovascular disease, and delirium were the independent risk predictors for sleep disorders. The nomogram showed high sensitivity and specificity of 75.6% and 72.9% in the ROC. The threshold probability of the net benefit was between 55% and 90% in the DCA. Conclusion The model showed high performance in predicting sleep disorders in ICU adults, the good clinical utility of which may be a useful tool for providing clinical decision support to improve sleep quality in the ICU.

The Effect of a Quality Improvement Intervention on Sleep and Delirium in Critically Ill Patients in a Surgical ICU. Chest 2021; 160:899-908. [PMID: 33773988 DOI: 10.1016/j.chest.2021.03.030] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Revised: 03/08/2021] [Accepted: 03/13/2021] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Delirium is a deleterious condition affecting up to 60% of patients in the surgical ICU (SICU). Few SICU-focused delirium interventions have been implemented, including those addressing sleep-wake disruption, a modifiable delirium risk factor common in critically ill patients. RESEARCH QUESTION What is the effect on delirium and sleep quality of a multicomponent nonpharmacologic intervention aimed at improving sleep-wake disruption in patients in the SICU setting? STUDY DESIGN AND METHODS Using a staggered pre-post design, we implemented a quality improvement intervention in two SICUs (general surgery or trauma and cardiovascular) in an academic medical center. After a preintervention (baseline) period, a multicomponent unit-wide nighttime (ie, efforts to minimize unnecessary sound and light, provision of earplugs and eye masks) and daytime (ie, raising blinds, promotion of physical activity) intervention bundle was implemented. A daily checklist was used to prompt staff to complete intervention bundle elements. Delirium was evaluated twice daily using the Confusion Assessment Method for the Intensive Care Unit. Patient sleep quality ratings were evaluated daily using the Richards-Campbell Sleep Questionnaire (RCSQ). RESULTS Six hundred forty-six SICU admissions (332 baseline, 314 intervention) were analyzed. Median age was 61 years (interquartile range, 49-70 years); 35% of the cohort were women and 83% were White. During the intervention period, patients experienced fewer days of delirium (proportion ± SD of ICU days, 15 ± 27%) as compared with the preintervention period (20 ± 31%; P = .022), with an adjusted pre-post decrease of 4.9% (95% CI, 0.5%-9.2%; P = .03). Overall RCSQ-perceived sleep quality ratings did not change, but the RCSQ noise subscore increased (9.5% [95% CI, 1.1%-17.5%; P = .02). INTERPRETATION Our multicomponent intervention was associated with a significant reduction in the proportion of days patients experienced delirium, reinforcing the feasibility and effectiveness of a nonpharmacologic sleep-wake bundle to reduce delirium in critically ill patients in the SICU.

Abstract
Introduction It has been repeatedly shown that sleep of intensive care unit (ICU) patients is fragmented and its architecture is impaired. As sleep disorders have numerous negative effects on the organism, there have been efforts to implement sleep-promoting strategies into practice. When comparing the effectiveness of such measures, sleep quality assessment itself is a considerable problem. Objective The study aimed to assess the quality and quantity of night sleep in ICU patients simultaneously with actigraphy (ACT) and the Richards-Campbell Sleep Questionnaire (RCSQ). The secondary goals were to test the performance and effectiveness of the above methods and to verify correlations between selected RCSQ items and actigraph parameters. Methods A single-center prospective observational study (20 patients staying in a Interdisciplinary Intensive Care Unit). The quality of sleep was assessed using a Czech version of the RCSQ and ACT. The obtained data were analyzed and their dependence or correlations were verified by selected statistical tests. Results The mean RCSQ score was 47.6 (SD 24.4). The worst results were found for sleep latency (44.4; SD 31.2); the best results were for sleep quality (50.2; SD 29.4). The mean sleep effciency measured with ACT reached 86.6% (SD 9.2); the mean number of awakenings per night was 17.1 (SD 8.5). The RCSQ total parameter with a cutoff of 50 (RCSQ total = 50 good sleep / RCSQ total < 50 poor sleep) was shown to be suitable for discrimination of subjectively perceived sleep quality in ICU patients. However, the study failed to show statistically significant relations between subjectively perceived sleep quality (RCSQ) and ACT measurements. Conclusion The RCSQ appears to be a suitable instrument for assessing night sleep quality in ICU patients. On the other hand, the study showed a very low level of agreement between subjective sleep quality assessment and objective ACT measurements. The main drawback of ACT is low reliability of obtained data. Further research is needed to determine its role in sleep quality assessment in the ICU setting.

Abstract
Sleep is fundamental for everyday functioning, yet it is often negatively impacted in critically ill patients by the intensive care setting. With a focus on the neurological intensive care unit (NeuroICU), this narrative review summarizes methods of measuring sleep and addresses common causes of sleep disturbance in the hospital including environmental, pharmacological, and patient-related factors. The effects of sleep deprivation on the cardiovascular, pulmonary, immune, endocrine, and neuropsychological systems are discussed, with a focus on short-term deprivation in critically ill populations. Where evidence is lacking in the literature, long-term sleep deprivation studies and the effects of sleep deprivation in healthy individuals are also referenced. Lastly, strategies for the promotion of sleep in the NeuroICU are presented.

Abstract
OBJECTIVES Sleep disturbances and delirium are frequently observed complications after surgical aortic valve replacement (SAVR) and transcutaneous aortic valve implantation (TAVI), especially in octogenarian patients. However, a knowledge gap exists on patient experiences of sleep and delirium. In particular, patients' long-term sleep and delirium experiences are unknown. This article explores and describes how octogenarian patients suffering from delirium after aortic valve replacement experience their sleep and delirium situation. DESIGN An explorative and descriptive design with a longitudinal qualitative approach was applied. Qualitative content analysis following the recommended steps of Graneheim and Lundman was performed. SETTING Patients were included at a tertiary university hospital with 1400 beds. Delirium and insomnia screening was performed at baseline and five postoperative days after aortic valve treatment. For qualitative data, 10 patients were interviewed 6-12 months after treatment with focus on delirium. Five of these patients were reinterviewed 4 years after treatment, with focus on their sleep situation. PARTICIPANTS Inclusion criteria; age 80+, treated with SAVR or TAVI and had experienced delirium after treatment. RESULTS For the initial interview, we included five men and five women, four following TAVI and six following SAVR, mean age 83. One overarching theme revealed from the content analyses; Hours in bed represented emotional chaos. Whereas three subthemes described the patients' experiences with sleep and delirium, a cascade of distressful experiences disturbing sleep, the struggle between sleep and activity and elements influencing sleep. Four years after the treatment, sleep disturbances persisted, and patients still remembered strongly the delirium incidences. CONCLUSIONS For octogenarian patients, sleep disturbances and delirium are long-term burdens and need a greater attention in order to improve patient care.

Abstract
WHAT IS KNOWN AND OBJECTIVE Delirium has been associated with increased mortality and prolonged hospital length of stay among critical care patients. Furthermore, treatment of delirium remains variable amongst clinicians due to limited evidence. The objective of this study was to determine the local incidence of delirium and to characterize the effectiveness and safety of pharmacological therapy used to treat delirium. METHODS A retrospective chart review evaluated patients diagnosed with delirium (Intensive Care Delirium Screening Checklist score ≥4) and requiring mechanical ventilation for ≥48 hours from January 2016 to June 2017. The primary outcomes included comparison of resolution, the time to first resolution and recurrence of delirium in patients prescribed pharmacological and/or pre-emptive therapy versus those who did not. Secondary outcomes included incidence of adverse effects of drug therapy and delirium attributable adverse events. RESULTS AND DISCUSSION The incidence of delirium during our defined study period was 49%. Of the 178 patients included in the study, 136 (76%) received drug therapy for delirium. Agents used for treatment of delirium included dexmedetomidine (n = 90 [66%]), haloperidol (n = 77 [57%]), and quetiapine (n = 74 [54%]). Resolution of delirium occurred in 94 (52%) of patients and the difference was statistically significant favoring patients who did not receive pharmacological therapy. There was no difference in the median time to resolution of delirium (3 days) for patients who received pharmacological and/or pre-emptive therapy versus those who did not. Bradycardia and hypotension were the most frequently documented medication-related adverse events. Self-removal of an invasive line/catheter, was reported in 36 (26%) patients despite receiving pharmacological treatment. WHAT IS NEW AND CONCLUSION Despite unclear evidence that pharmacological interventions help with delirium management, the majority of our patients received such interventions. To improve patient outcomes, we should shift focus towards non-pharmacological interventions for delirium.

Abstract
OBJECTIVES To determine whether total daily 6-sulfatoxymelatonin excretion and diurnal variation of melatonin secretion was maintained during the early phase of PICU admission through examination of the melatonin urinary metabolite, 6-sulfatoxymelatonin. DESIGN Exploratory prospective, observational study. SETTING Twelve-bed medical-surgical PICU of a Children's Hospital. PATIENTS Fifty children 3 months to 18 years old enrolled within 24 hours of PICU admission with access for urinary sampling. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Urine samples were collected at 4-hour intervals for 24 hours and stored at -80C. 6-sulfatoxymelatonin was determined in duplicate by direct enzyme-linked immunosorbent assay. Patients were heterogeneous for diagnosis, had a mean age of 8.1 years (SD = 6.1 yr), and median (interquartile range) Pediatric Risk of Mortality III of 10 (4-13). Mean (SD) total daily 6-sulfatoxymelatonin production was 30.0 µg (25.6 µg) for the first 24 hours, which did not differ significantly from the means on days 2 (p = 0.56) or 3 (p = 0.29), and was similar to literature controls. Mean 6-sulfatoxymelatonin production for the population fit a periodic function well, with a reliable amplitude of 326 ng/hr and peak excretion from 04:00 to 08:00 (F = 4.4, p = 0.01), even when 6-sulfatoxymelatonin was corrected for body weight (F = 3.4, p = 0.03) and when sedation was included in the model (F = 3.95, p = 0.004). There was no significant correlation between lighting and 6-sulfatoxymelatonin excretion at any time period (R values: 0.11-0.25, p = 0.10-0.94). Mean 6-sulfatoxymelatonin excretion did not fit the model for a periodic function well for the subpopulations studied (sepsis [n = 18, F = 1.1, p = 0.32], respiratory failure requiring deep sedation [n = 10, F = 0.4, p = 0.66], and neurologic injury [n = 7, F = 0.6, p = 0.55]). CONCLUSIONS Total daily and diurnal variation of 6-sulfatoxymelatonin excretion is heterogeneously maintained early in pediatric critical illness. However, this may not hold true for specific diagnostic categories.

Abstract
OBJECTIVE Evidence-based guidelines recommend promoting sleep in the Intensive Care Unit (ICU), yet many patients experience poor sleep quality. We sought to engage allied health staff and patient families to determine barriers to sleep promotion, to measure sleep quality for ICU patients, and to evaluate the improvement in sleep quality after implementation of nursing morning report protocol and a doorway poster. DESIGN The study followed an interrupted time-series framework of quality improvement. Qualitative diagnostics included focus groups and interviews with patients, families, and allied health care workers, analyzed by qualitative descriptive analysis. Quantitative diagnostics included direct observation of nurses and patients overnight. Analysis of primary outcome data used statistical process control methodology. PATIENTS Patients included were >18 years old, admitted overnight to a Canadian tertiary academic ICU, with a Richards Agitation Sedation Scale (RASS) ≥-2. INTERVENTIONS Sleep quality was measured using the Richards Campbell Sleep Questionnaire (RCSQ). Two interventions were developed: sleep quality in morning nursing report, and a doorway poster. MAIN RESULTS A total of 2332 patient nights across 7 consecutive months were included for analysis. Baseline sleep in the ICU was poor (mean RCSQ 53.7/100). Root cause-analysis identified the most prominent sleep barriers as nurse stigma associated with less active management of patients and lack of physician engagement. No significant improvement occurred over the sleep quality improvement initiative (mean RCSQ 59.5/100). Sleep quality was better among non-delirious patients compared with delirious patients (mean RCSQ 62.7 vs 53.3). CONCLUSION The intervention of a nursing morning report protocol and sleep posters did not improve the quality of ICU patient sleep in this study. Structured interviews revealed potential sleep barriers to be addressed such as nursing stigma and inappropriate awakenings. Nursing stigma has not been previously linked to sleep quality.

Abstract
Delirium is a syndrome characterized by acute brain failure resulting in neurocognitive disturbances affecting attention, awareness, and cognition. It is highly prevalent among critically ill patients and is associated with increased morbidity and mortality. A core domain of delirium is represented by behavioral disturbances in sleep-wake cycle probably related to circadian rhythm disruption. The relationship between sleep, circadian rhythm and intensive care unit (ICU)-acquired delirium is complex and likely bidirectional. In this review, we explore the proposed pathophysiological mechanisms of sleep disruption and circadian dysrhythmia as possible contributing factors in transitioning to delirium in the ICU and highlight some of the most relevant caveats for understanding the relationship between these complex phenomena. Specifically, we will (1) review the physiological consequences of poor sleep quality and efficiency; (2) explore how the neural substrate underlying the circadian clock functions may be disrupted in delirium; (3) discuss the role of sedative drugs as contributors to delirium and chrono-disruption; and, (4) describe the association between abnormal sleep-pathological wakefulness, circadian dysrhythmia, delirium and critical illness. Opportunities to improve sleep and readjust circadian rhythmicity to realign the circadian clock may exist as therapeutic targets in both the prevention and treatment of delirium in the ICU. Further research is required to better define these conditions and understand the underlying physiologic relationship to develop effective prevention and therapeutic strategies.

Abstract
Delirium is a multifactorial syndrome and is described as an acute brain dysfunction seen commonly in post-cardiac surgery patients. The prevalence of post-operative Delirium (POD) ranges from 11.4% to 55%, depending on the diagnostic tool and type of study. Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) and the Intensive Care Delirium Screening Checklist (ICDSC) are the two most used and recommended tools by the Society of Intensive Care Medicine. Annual delirium-related healthcare costs in the United States (US) range from 6.6 to 20.4 billion USD in ICU patients. However, delirium in cardiac ICU (CICU) is underdiagnosed and warrants vigorous workup. The risk factors for delirium in CICU can be classified as modifiable, non-modifiable, and cardiac surgical causes. After cardiac procedures, delirium is associated with increased mortality, increased length of hospital stay, loss of functional independence, increased hospital costs, and an independent predictor of death 10 years postoperatively. Non-pharmacological measures such as avoiding delirium-risk medications, early physical rehabilitation, occupational therapy, and sleep improvement strategies have shown significant benefits in decreasing delirium. Pharmacological options are limited for use in CICU, and a need for future studies in this topic is in demand.

Abstract
Purpose of Review Poor sleep and delirium are common in older patients but recognition and management are challenging, particularly in the intensive care unit (ICU) setting. The purpose of this review is to highlight current research on these conditions, their inter-relationship, modes of measurement, and current approaches to management. Recent Findings Sleep deprivation and delirium are closely linked, with shared clinical characteristics, risk factors, and neurochemical abnormalities. Acetylcholine and dopamine are important neurochemicals in the regulation of sleep and wakefulness and their dysregulation has been implicated in development of delirium. In the hospital setting, poor sleep and delirium are associated with adverse outcomes; non-pharmacological interventions are recommended, but tend to be resource intensive and hindered by a lack of reliable sleep measurement tools. Delirium is easier to identify, with validated tools available in both ICU and non-ICU settings; however, an optimal treatment approach remains unclear. Antipsychotics are used widely to prevent and treat delirium, although the efficacy data are equivocal. Bundled non-pharmacologic approaches represent a promising framework for prevention and management. Summary Poor sleep and delirium are common problems in older patients. While these phenomena appear linked, a causal relationship is not clearly established. At present, there are no established sleep-focused guidelines for preventing or treating delirium. Novel interventions are needed that address poor sleep and delirium, particularly in older adults.

Abstract
Objective To conduct a national survey of intensive care professionals to identify the practices for promoting sleep in adult intensive care units in Brazil and describe the professionals’ perceptions of the importance of sleep for patients. Methods An electronic questionnaire was distributed by the clinical research cooperation network of the Associação de Medicina Intensiva Brasileira and by the Brazilian Research in Intensive Care Network to physicians and nurses registered with the association. The questionnaire evaluated the profile of the respondents, the profile of their intensive care units, whether protocols for promoting sleep were present, the pharmacological and nonpharmacological measures typically employed in the unit, and the professionals’ perceptions regarding sleep in critically ill patients. Results A total of 118 questionnaires were evaluated. The Southeast region of the country was the most represented (50 questionnaires, 42.4%). The majority of units had a clinical-surgical profile (93 questionnaires; 78.8%), and 26 had a continuous visitation policy (22.0%). Only 18 intensive care units (15.3%) reported having protocols for promoting sleep. The most cited measure for sleep promotion was reducing light during the night (95 questionnaires; 80.5%), which was more often performed in private intensive care units. Almost all of the responders (99%) believed that poor-quality sleep has a negative impact on patient recovery. Conclusion The responses to this Brazilian survey revealed that few intensive care units had a program for promoting sleep, although almost all participants recognized the importance of sleep in patient recovery.

Abstract
Background Delirium is a common condition in critically ill patients, affecting nearly half of all patients admitted to an intensive care unit (ICU). Family caregivers of critically ill patients can be partners in the early recognition, prevention and management of delirium provided they are aware of the signs/symptoms and appropriate non-pharmacological strategies that might be taken. Valid, reliable instruments that assess family caregiver knowledge are essential so that nurses can prepare family caregivers to be effective partners. The purpose of the current study was to (a) adapt an existing caregiver delirium knowledge questionnaire (CDKQ) for use by nurses to measure a family caregiver’s delirium knowledge in the ICU; and (b) examine the psychometric properties and structure of the adapted Caregiver ICU Delirium Knowledge Questionnaire (CIDKQ). Methods In this cross-sectional study, a multidisciplinary team developed the 21-item CIDKQ (possible score range: 0–21) and administered it to 158 family caregivers of critically ill patients. Descriptive statistics were examined for all variables. The CIDKQ was analyzed for face validity, content validity, reliability and internal consistency. Results The mean CIDKQ score was 14.1 (SD: 3.5, range = 2 to 21). Path analysis revealed that a family caregiver’s delirium knowledge in the actions and symptoms dimensions had a direct effect on knowledge of delirium risk factors. The CIDKQ was found to have face validity and reliability (Cronbach’s α = 0.79). Conclusions The findings indicated good validity and reliability of the CIDKQ as a measure of ICU delirium knowledge in family caregivers of critically ill patients.

Abstract
Study Objectives Following extubation in the intensive care unit (ICU), upper airway (UA) edema and respiratory depressants may promote UA dysfunction. We tested the hypothesis that opioids increase the risk of sleep apnea early after extubation. Methods Fifty-six ICU patients underwent polysomnography the night after extubation. Airflow limitation during wakefulness was identified using bedside spirometry. Correlation and ordinal regression analyses were used to quantify the effects of preextubation opioid dose on postextubation apnea-hypopnea index (AHI) and severity of sleep apnea and whether or not inspiratory airway obstruction (ratio of maximum expiratory and inspiratory airflows at 50% of vital capacity [MEF50/MIF50] ≥ 1) during wakefulness predicts airway obstruction during sleep. Data were adjusted for age, gender, body mass index, as well as a generalized propensity score balanced for APACHE II, score for preoperative prediction of obstructive sleep apnea, duration of mechanical ventilation, chronic obstructive pulmonary disease, and a procedural severity score for morbidity. Results Sleep apnea (AHI ≥ 5) was present in 40 (71%) of the 56 patients. Morphine equivalent dose given 24 hours prior extubation predicted obstructive respiratory events during sleep (r = 0.35, p = .01) and sleep apnea (odds ratio [OR] 1.17; 95% confidence interval [CI] 1.02-1.34). Signs of inspiratory UA obstruction (MEF50/MIF50 ≥ 1) assessed by bedside spirometry were strongly associated with sleep apnea (OR 5.93; 95% CI 1.16-30.33). Conclusions High opioid dose given 24 hours prior to extubation increases the likelihood of postextubation sleep apnea in the ICU, particularly in patients with anatomical vulnerability following extubation.

Abstract
Delirium is a serious complication of acute illness. Little is known, however, regarding the neurobiology of delirium, largely due to challenges in studying the complex inpatient population. Neuroimaging is one noninvasive method that can be used to study structural and functional brain abnormalities associated with delirium. The purpose of this integrative literature review was to examine the content and quality of current structural neuroimaging evidence in delirium. After meeting inclusion criteria, 11 articles were included in the review. Commonly noted structural abnormalities were impaired white matter integrity, brain atrophy, ischemic lesions, edema, and inflammation. Findings demonstrated widespread alterations in several brain structures. Limitations of the studies in this review included small sample sizes, inappropriate or questionable delirium measurements, and failure to consider confounding variables. This review provides insight into possible structural changes responsible for the signs and symptoms seen in patients with delirium, but more high-quality studies are needed.

Abstract
AIMS AND OBJECTIVES To create a framework for future research through application and critique of the Life Course Health Development Model to the phenomenon of paediatric delirium. BACKGROUND Delirium in the paediatric intensive care unit is associated with increased duration of mechanical ventilation, length of stay and mortality. Nurses are uniquely positioned at the bedside to identify, prevent and treat delirium. An understanding of the potential long-term consequences of paediatric delirium is necessary to provide impetus for nursing research and practice change. The Life Course Health Development Model is a valuable tool when considering the multiple mechanisms and processes through which the experience of delirium could affect a child's life trajectory. DESIGN Critical review of the literature through application and critique of the Life Course Health Development Model in the context of paediatric delirium. Gaps in the current understanding of paediatric delirium, as well as future directions for research and practice, are discussed. METHODS The seven core principles of the model are considered in the context of paediatric delirium. Each of the principles has the potential to further understanding of paediatric delirium and identify areas for future inquiry. This discussion leads to a critique of the ability of the model to lead future research and practice change. CONCLUSIONS The Life Course Health Development Model depicts a process in which the acute and severe stress of critical illness leads to maladaptive neurologic changes that contribute to the development of delirium and impair a child's life trajectory. RELEVANCE TO CLINICAL PRACTICE By emphasising the potential lifelong consequences for critically ill children who experience delirium, this application of the Life Course Health Development Model will stimulate discussion, research and practice change among paediatric clinicians and researchers.

Abstract
STUDY OBJECTIVES Delirium is a postoperative complication accompanied by disturbances in attention, cognition, arousal, and psychomotor activity. Wrist actigraphy has been advocated to study inactivity and inferred sleep patterns during delirium. We hypothesized that altered patterns of motor activity or immobility, reflective of disordered sleep and wakefulness patterns, would serve as predictive markers of hypoactive postoperative delirium. METHODS Eighty-four elderly surgical patients were classified into three groups based on the timing of hypoactive delirium following surgery: intact with no delirium throughout postoperative days (POD) 0-5 (n = 51), delirium during POD 0-1 (n = 24), and delirium during POD 2-5 (n = 13). Delirium was detected on daily Confusion Assessment Method evaluations and chart review. Actigraphy measures were calculated from accelerometry signals acquired on the first postoperative day (POD 0, 16:00-23:00) and night (POD 0, 23:00-POD 1, 06:00). RESULTS Actigraphy metrics showed substantial interpatient variability. Among the three patient groups, only those without delirium showed greater movement during the day compared to night and also fewer minutes of night immobility (P = .03 and P = .02, Wilcoxon rank-sum tests). These patients were poorly discriminated from those with delirium during either POD 0-1 or POD 2-5, using differences in day and night activity (C-statistic, 95% confidence interval [CI]: 0.66 [0.53-0.79] and C-statistic, 95% CI: 0.71 [0.55-0.87], respectively). Inclusion of low-frequency signals improved performance of immobility measures without affecting those based on activity. Cognitively intact patients during POD 0-5 were distinguished from those with delirium during POD 0-1, based on differences in the number of day and night immobile minutes (C-statistic 0.65, 95% CI: [0.53-0.78]). Actigraphy metrics with the strongest association to delirium incidence were not reliably correlated with an increased risk during POD 0-5, when accounting for patient age, sex, intensive care unit admission, and Charlson Comorbidity Index (adjusted odds ratio of 1.7, 95% CI: [1.0-3.0], P = .09, likelihood ratio test). CONCLUSIONS Early postoperative wrist actigraphy metrics that serve as markers of sleep and wakefulness offer limited capacity as sole predictors or markers of hypoactive delirium.

Abstract
With growing recognition of pediatric delirium in pediatric critical illness there has also been increased investigation into improving recognition and determining potential risk factors. Disturbed sleep has been assumed to be one of the key risk factors leading to delirium and is commonplace in the pediatric critical care setting as the nature of intensive care requires frequent and invasive monitoring and interventions. However, this relationship between sleep and delirium in pediatric critical illness has not been definitively established and may, instead, reflect significant overlap in risk factors and consequences of underlying neurologic dysfunction. We aim to review the existing tools for evaluation of sleep and delirium in the pediatric critical care setting and review findings from recent investigations with application of these measures in the pediatric intensive care unit.

Abstract
Sleep is markedly altered in intensive care unit (ICU) patients and may alter respiratory performance. Our objective was to assess the impact of sleep alterations on weaning duration.We conducted a prospective physiological study at a French teaching hospital. ICU patients intubated for at least 24 h and difficult to wean were included. Complete polysomnography (PSG) was performed after the first spontaneous breathing trial failure. Presence of atypical sleep, duration of sleep stages, particularly rapid eye movement (REM) sleep, and electroencephalogram (EEG) reactivity at eyes opening were assessed by a neurologist.20 out of 45 patients studied (44%) had atypical sleep that could not be classified according to the standard criteria. Duration of weaning between PSG and extubation was significantly longer in patients with atypical sleep (median (interquartile range) 5 (2–8) versus 2 (1–2) days; p=0.001) and in those with no REM sleep compared with the others. Using multivariate logistic regression analysis, atypical sleep remained independently associated with prolonged weaning (>48 h after PSG). Altered EEG reactivity at eyes opening was a good predictor of atypical sleep.Our results suggest for the first time that brain dysfunction may have an influence on the ability to breathe spontaneously.
