Interventions to improve inpatients' sleep quality in intensive care units and acute wards: a literature review

Relationship between inflammatory factors, lactic acid levels, acute skin failure, bad mood, and sleep quality

BACKGROUND

The central link between septic shock and acute skin failure (ASF) is the inflammatory response, which occurs throughout disease progression and can lead to systemic inflammatory response syndrome. Patients often experience bad moods, sleep disorders, and other health issues. Despite recognizing these factors, no studies have examined the correlation between inflammatory factors, lactic acid levels, ASF, mood disturbances, and sleep quality in critically ill patients. We hypothesize that higher levels of inflammatory factors and lactic acid are associated with more severe ASF and poorer mood and sleep quality, which may inform clinical treatment for septic shock and ASF.

AIM

To explore the relationship between inflammatory factors, lactic acid levels, the severity of ASF, bad mood, and sleep quality.

METHODS

The retrospective study included 150 patients with septic shock from the Second Hospital of Dalian Medical University, categorized into ASF (n = 35) or non-ASF groups (n = 115). We compared the peripheral blood inflammatory factors, including tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), interleukin-6 (IL-6), lactic acid levels, skin mottling score (SMS), modified early warning score (MEWS), self-rating depression scale (SDS), self-rating anxiety scale (SAS), and Pittsburgh sleep quality index (PSQI) scores. Pearson correlation analysis assessed relationships among these variables.

RESULTS

The ASF group had significantly higher levels of CRP (19.60 ± 4.10 vs 15.30 ± 2.96 mg/mL), IL-6 (298.65 ± 48.65 vs 268.66 ± 33.66 pg/L), procalcitonin, lactic acid (8.42 ± 2.32 vs 5.70 ± 1.27 mmol/L), SMS [0 (0, 1) vs 3 (2, 3)], MEWS (9.34 ± 1.92 vs 6.48 ± 1.96), SAS (61.63 ± 12.03 vs 53.71 ± 12.48), SDS (60.17 ± 12.64 vs 52.27 ± 12.64), and PSQI scores (14.23 ± 3.94 vs 8.69 ± 2.46) compared with the non-ASF group (all P < 0.001). Pearson correlation analysis revealed that IL-6, CRP, TNF-α, and lactic acid were positively correlated with SMS, MEWS, SAS, SDS, and PSQI scores (P < 0.05).

CONCLUSION

Peripheral blood levels of IL-6, CRP, TNF-α, and lactic acid correlate positively with SMS, MEWS, SAS, SDS, and PSQI in critically ill patients with ASF.

An opportunity to sleep well in hospital: development of a multi-level intervention to improve inpatient sleep (ASLEEP) using behaviour change theories

BACKGROUND

Sleep is substantial issue for hospital inpatients and can negatively affect healing and recovery. There is a good evidence-base for interventions which can improve sleep, however currently they are not being implemented into NHS practice. To address the evidence-practice gap, we have conducted early-phase development for an inpatient sleep intervention (ASLEEP); a multi-level intervention to improve inpatient sleep in UK hospital wards.

METHODS

We used an iterative development process incorporating Patient and Public Involvement and Engagement, ward staff surveys and stakeholder consultations (orthopaedic and acute medicine), and theoretical mapping using behaviour change theories. Development took place in four stages: identification of existing patient-level intervention components to improve sleep in hospital; identification of environmental barriers and facilitators to sleep in hospital; consultation with health professional stakeholders; and final theoretical mapping using the COM-B model and Theoretical Domains Framework, also considering who holds 'change power' for each change construct.

RESULTS

We identified 18 variables contributing to inpatient sleep, which are malleable to change universally across hospital wards. Central domains for change were identified as the ward environment context and resources; to reduce noise from equipment (material resources), and social influence; to modulate staff and patient noise awareness and behaviours (group norms). Change power mapping identified key stakeholders as patients, ward staff, procurement/estates, and NHS management.

CONCLUSIONS

Improving sleep in hospital requires a whole-systems approach which targets environmental factors, staff behaviour, and patient behaviour. We have provided recommendations for a multi-level intervention, highlighting core areas for change and essential stakeholders who must be involved to progress implementation. The next stage of development will involve operationalising recommendations and piloting, including evaluating mechanisms of change. It will be important to continue working with a broad range of stakeholders to bridge the evidence-practice gap and support sustainable practice adoption.

Sleep quality assessment of adults in care settings using non-wearable sleep trackers: Scoping review

AIMS

This review aimed to explore and map the literature on sleep quality assessments of adults in care settings using non-wearable sleep trackers.

BACKGROUND

Sleep-monitoring technology is advancing, and sleep quality assessments using non-wearable sleep trackers can provide objective evidence for quality care.

DESIGN

This was a scoping review.

DATA SOURCES

Four electronic databases (PubMed, CINAHL, PsycInfo and Embase) were searched on 23 September 2022.

REVIEW METHODS

This review followed the Joanna Briggs Institute's methodology and used the PRISMA-ScR checklist.

RESULTS

Thirty studies met our inclusion criteria. Sleep quality was assessed at home and in acute, non-acute and long-term care facilities. Physiological (heart rate and respiratory rate) and sleep parameters were assessed alone or in combination during patient care using non-wearable sleep trackers. Sleep parameters representing sleep quality varied across studies. Real-time monitoring with non-wearable sleep-tracking devices effectively shortened the length of hospital stay. However, studies investigating caregivers and nursing outcomes are lacking in the literature.

CONCLUSION

Sleep quality assessments using non-wearable sleep trackers may facilitate the provision of quality care in home-based and clinical care settings. Future studies should focus on caregivers and care outcomes that could contribute to evidence-based nursing practice for sleep care in adults.

Based -evidence, an intervention study to improve sleep quality in awake adult ICU patients: a prospective, single-blind, clustered controlled trial

BACKGROUND

Evidence-based guidelines advocate promoting sleep in intensive care unit (ICU) patients, yet many patients experience poor sleep quality. We sought to develop a collaborative evidence-based intervention with healthcare providers and assess whether evidence-based sleep interventions could improve sleep quality in awake adult ICU patients.

METHODS

We conducted a prospective, nonrandomized cluster control trial in two intensive care units (ICUs) at a tertiary general teaching hospital in China. Patients aged 18 years or older who stayed in the ICU for one night or more and were conscious were eligible for enrollment. We only blinded the patients, not the outcome assessors. On the basis of evidence-based practice and clinical reality, we developed intervention measures for the intervention group, which mainly included four aspects: reducing environmental noise in the ICU, adjusting nursing actions, modifying nighttime lighting, and other measures. The assessment tools used were wearable actigraphy sleep monitoring devices and the Richards-Campbell Sleep Questionnaire (RCSQ). The primary outcomes were patient sleep quality, including total sleep time, deep sleep time, light sleep time, rapid eye movement (REM) time, number of awakenings, overall sleep score, and patients' self-assessment of their sleep quality that night. The data collected were analyzed via SPSS and Mplus statistical software for between-group analysis, pre-post comparison, profile analysis, and calculation of the intervention effect size.

RESULTS

From September 1, 2023, to January 31, 2024, 713 patients underwent eligibility assessment, and ultimately 246 patients were included in the analysis, with 125 in the intervention group and 121 in the control group. Comparative analysis revealed no statistically significant differences in sleep quality between the two groups when the duration in the ICU = 1 night (P > 0.05), with a small intervention effect size. However, the intervention group had higher sleep quality scores (sleep monitoring wristband: 57.74 ± 22.55 > 57.72 ± 19.39; RCSQ questionnaire: 60.58 ± 22.14 > 57.61 ± 24.4) and total sleep time (440.42 ± 262.11 > 420.31 ± 236.89), a lower awakening frequency (3.98 ± 2.69 < 6.09 ± 4.66) and a lower awakening frequency (3.976 ± 2.693 < 6.09 ± 4.664) than did the control group. The sleep quality of patients who stayed in the ICU for > 1 night significantly improved in all the parameters except rapid eye movement time (min) according to the pre-post-test analyses (P < 0.05), with a medium to large intervention effect size and favorable intervention effects.

CONCLUSION

Evidence-based interventions significantly improve sleep quality in ICU patients hospitalized for more than one day. However, our results do not support the improvement of sleep quality in patients admitted to the ICU for one day.

Were there any missing mediators between visual impairment and anxiety symptoms? Results from Chinese Longitudinal Healthy Longevity Survey

Introduction

Visual impairment, encompassing low visual acuity and visual field loss, significantly impacts the older adult population worldwide, leading to increased disability and mortality risks. Recent studies suggest a strong association between visual impairment and anxiety, particularly among older adults. This study aims to explore the relationship between visual impairment and anxiety symptoms in older adult individuals in China, and to investigate potential mediating factors.

Methods

Data for this study were derived from the 2018 Chinese Longitudinal Healthy Longevity Survey (CLHLS), including 11,702 participants aged 65 and older. Visual impairment was assessed through self-reported visual function, while anxiety symptoms were measured using the 7-item Generalized Anxiety Disorder scale (GAD-7). Additional assessments included sleep quality and duration, exercise status, and dietary diversity. Logistic regression models and mediation analysis were employed to explore associations and mediating effects.

Results

The findings indicate that visual impairment is significantly associated with increased anxiety symptoms among the older adult (OR = 1.51, 95% CI: 1.32-1.72, p < 0.001). Mediation analysis revealed that sleep quality, dietary diversity score (DDS), and plant-based DDS significantly mediated the relationship between visual impairment and anxiety. In contrast, sleep duration, exercise, and animal-based DDS did not show significant mediating effects.

Conclusion

Visual impairment is a crucial predictor of anxiety symptoms in the older adult. Improving sleep quality and promoting a diverse plant-based diet may mitigate anxiety symptoms in this population. Interventions targeting these areas could enhance the mental health and quality of life of older adult individuals with visual impairment.

Effect of the Levels and Sources of Noise on the Sleep Quality of Conscious Patients in Emergency Intensive Care Unit

PURPOSE

This study aimed to assess the levels and sources of noise in the emergency intensive care unit (EICU) of an emergency department and investigate their effects on the sleep quality of conscious patients.

METHODS

A study was conducted on patients admitted to the EICU from December 2020 to December 2023. They were categorised according to their sleep quality with the Pittsburgh Sleep Quality Index. Environmental noise levels were measured using precision sound level metres and environmental noise automatic monitoring instruments. Data analysis was performed using SPSS version 25.0, and Chi-square test, Fisher's exact probability and t-tests were conducted when applicable. The significance threshold was set at P < 0.05. Regression analysis was carried out for indicators with significant differences.

RESULTS

A total of 200 patients were included in the study. Of them 96 in the ideal sleep group and 104 in the non-ideal sleep group. Patients with non-ideal sleep experienced significantly higher noise levels across various measures (P < 0.05). Additionally, patients with non-ideal sleep reported significantly higher occurrences of noise-related awakening, difficulty in falling asleep, nightmares or vivid dreams and sleepwalking episodes (P < 0.05). Significant differences in staff activities, including staff conversations, equipment noise exposure, cleaning activities, patient interventions and overhead pages, were observed between the groups (P < 0.05). Multivariate logistic regression analysis indicating that the average noise level, conversational speech, equipment alarms, ambient noise, peak noise levels, staff conversations, cleaning activities, patient interventions and overhead pages were significant contributors to poor sleep.

CONCLUSION

The study suggested that high noise levels and staff-related activities affected the sleep quality of conscious patients in the EICU. Targeted measures could improve the prognoses of patients.

Association of sleep fragmentation with general and abdominal obesity: a population-based longitudinal study

OBJECTIVE

To evaluate the causal relationship between sleep fragmentation (SF) parameters with general and abdominal obesity in free-living conditions.

METHODS

SF parameters were assessed by ActiGraph accelerometers for 7 consecutive days. Obesity was measured at baseline and 1-year follow-up with InBody S10 body composition analyzer.

RESULTS

At baseline, the mean age of the study population was 18.7 years old (SD = 0.9) and 139 (35.7%) were male. Each 1-unit increase of baseline sleep fragmentation index (SFI) was associated with 0.08 kg/m2-increase of body mass index (BMI) (95% CI: 0.03, 0.14), 0.20%-increase of percentage of body fat (PBF) (95% CI: 0.07, 0.32), 0.15 kg-increase of fat mass (FM) (95% CI: 0.03, 0.27), 0.15 cm-increase of waist circumference (WC) (95% CI: 0.03, 0.26) and 0.91 cm2-increase of visceral fat area (VFA) (95% CI: 0.36, 1.46) at the 1-year follow-up. In addition, each 1-unit increase of baseline SFI was associated with 15% increased risk of general obesity (OR = 1.15, 95% CI = 1.04-1.28; p = 0.006) and 7% increased risk of abdominal obesity (OR = 1.07, 95% CI = 1.01-1.13; p = 0.021) in the following year.

CONCLUSIONS

Fragmented sleep is independently associated with an increased risk of both general and abdominal obesity. The result highlights SF as a modifiable risk factor for the prevention and treatment of obesity.

Effect of Comprehensive Noise Reduction Management on the Postoperative Negative Emotion, Stress Response Hormone and Sleep Status of Burn Patients: Single-Centre Retrospective Analysis

OBJECTIVE

This study aimed to explore the effect of comprehensive noise reduction management on the postoperative recovery of burn patients.

METHODS

Data of 156 patients admitted to Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University from October 2022 to July 2023 were retrospectively analysed. The patients were divided into two groups according to the management method: group A (n = 76, standard care of burns) and group B (n = 80, standard care of burns+comprehensive noise reduction management). The stress response level, anxiety and depression level, sleep quality and satisfaction of the two groups were compared before and after the management.

RESULTS

Before the management, no statistically significant differences in cortisol (Cor), anxiety and depression scores and sleep quality were found between the two groups (P > 0.05). After the management, significant differences in Cor, anxiety scores, sleep quality and patient satisfaction were observed between the two groups (P < 0.001).

CONCLUSIONS

Comprehensive noise reduction management can reduce postoperative stress hormone levels, alleviate negative emotions, such as anxiety, and improve sleep quality and patient satisfaction.

Effects of Ward Noise Reduction Administration on Mental Health and Lung Function of Patients with Lung Cancer

OBJECTIVE

This study aimed to analyze the effects of ward noise reduction administration on the lung function and mental health of patients with lung cancer.

METHODS

A total of 195 patients who underwent lung cancer surgery in PLA Northern Theater Command Air Force Hospital from November 2020 to November 2022 were selected to be divided into a control group (routine nursing) and an observation group (routine nursing and ward noise reduction administration) in accordance with the medical record system. The general demographic data, noise level, lung function (forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and FEV1/FVC)), and complications of patients in the two groups were collected. Propensity score matching (PSM) was used to balance the baseline data of the two groups, and t-test and chi-square test were used to analyze the data.

RESULTS

After PSM was conducted, 50 patients were enrolled in each group. No statistical difference was found in the baseline data, preadministration noise levels, and FEV1, FVC, FEV1/FVC, state-anxiety inventory (S-AI), and trait anxiety inventory scale (T-AI) scores between the two groups (P > 0.05). After ward noise reduction was administered, the noise level in the observation group was lower than that in the control group (P < 0.05). The FEV1, FVC, and FEV1/FVC scores of the observation group were higher than those of the control group but were not statistically significant (P > 0.05). The S-AI and T-AI scores of the observation group were lower than those of the control group (P < 0.05). No differences were found in the complications between the two groups (P > 0.05).

CONCLUSION

Administering ward noise reduction in patients with lung cancer can alleviate their negative emotions, thus worthy of clinical adoption.

Non-pharmacological interventions to improve sleep quality and quantity for hospitalized adult patients-co-produced study with surgical patient partners: systematic review

BACKGROUND

Hospitalized patients experience sleep disruption with consequential physiological and psychological effects. Surgical patients are particularly at risk due to surgical stress and postoperative pain. This systematic review aimed to identify non-pharmacological interventions for improving sleep and exploring their effects on sleep-related and clinical outcomes.

METHODS

A systematic literature search was performed in accordance with PRISMA guidelines and was preregistered on the Open Science Framework (doi: 10.17605/OSF.IO/EA6BN) and last updated in November 2023. Studies that evaluated non-pharmacological interventions for hospitalized, adult patients were included. Thematic content analysis was performed to identify hypothesized mechanisms of action and modes of administration, in collaboration with a patient partner. Risk of bias assessment was performed using the Cochrane Risk Of Bias (ROB) or Risk Of Bias In Non-Randomized Studies - of Interventions (ROBINS-I) tools.

RESULTS

A total of 59 eligible studies and data from 14 035 patients were included; 28 (47.5%) were randomized trials and 26 included surgical patients (10 trials). Thirteen unique non-pharmacological interventions were identified, 17 sleep measures and 7 linked health-related outcomes. Thematic analysis revealed two major themes for improving sleep in hospital inpatients: enhancing the sleep environment and utilizing relaxation and mindfulness techniques. Two methods of administration, self-administered and carer-administered, were identified. Environmental interventions, such as physical aids, and relaxation interventions, including aromatherapy, showed benefits to sleep measures. There was a lack of standardized sleep measurement and an overall moderate to high risk of bias across all studies.

CONCLUSIONS

This systematic review has identified several sleep interventions that are likely to benefit adult surgical patients, but there remains a lack of high-quality evidence to support their routine implementation.

Longitudinal patterns of patient-reported sleep disturbances after surgery for lung cancer

PURPOSE

The purpose of this study was to identify longitudinal heterogeneous trajectories of sleep status, adjusted for the effect of pain over time, among patients who had surgery for lung cancer and to quantify how disturbed sleep in the hospital affects functional recovery after discharge.

METHODS

We included patients from a surgical cohort (CN-PRO-Lung 1). All patients reported symptoms using the MD Anderson Symptom Inventory-Lung Cancer (MDASI-LC) daily during postoperative hospitalization. Group-based dual trajectory modeling was used to investigate trajectories of disturbed sleep and pain during the first 7 days of postoperative hospitalization. Cox regression was used to compare the recovery of walking ability between the different sleep trajectories.

RESULTS

Among 421 patients, disturbed sleep trajectories comprised low (31%), moderate (52%), and high (17%) groups. The surgical approach and number of chest tubes were associated with pain, and the number of chest tubes was also associated with sleep disturbances (OR = 1.99; 95% CI: 1.08-3.67). Recovery of walking ability after discharge was significantly slower in the high (median days = 16; 95% CI: 5-NA) and moderate disturbed sleep trajectory groups (median days = 5; 95%CI: 4-6) than in the low group (median days = 3; 95% CI: 3-4).

CONCLUSION

Changes in disturbed sleep among patients with lung cancer followed three distinct trajectories over the first 7 days of hospitalization after surgery. Dual trajectory analyses highlighted the high concordance between specific trajectories of disturbed sleep and pain. Patients at high sleep disturbance and high levels of pain may benefit from appropriate interventions for both symptoms in combination with the patient's surgical approach and the number of chest tubes.

Evaluation on the Effect of Ward-Noise Reduction Management Combined with Monitoring-Training-Planning Management Mode in Hospitalized Patients with Heart Failure

BACKGROUND

Noise from medical institutions such as hospitals usually exceeds the level recommended by the World Health Organization. This study aimed to explore the application effect of ward-noise reduction management combined with monitoring-training-planning (MTP) management mode in hospitalized patients with heart failure.

MATERIALS AND METHODS

Among the 168 research objects, 55 patients with heart failure receiving ward-noise reduction management combined with MTP management mode from April 2022 to March 2023 were included in group A, 52 patients with heart failure who underwent MTP management mode from March 2021 to March 2022 were selected as group B, and 61 patients who underwent routine management measures from March 2020 to February 2021 served as the control group. The vital signs, Self-rating Anxiety Scale (SAS) scores, Self-rating Depression Scale (SDS) scores, physical function indices, sleep quality score, and satisfaction degree of patients in the three groups were compared before and after management.

RESULTS

After 1 month of management, group A had lower heart rate, diastolic blood pressure, systolic blood pressure, and respiratory rate compared to group B and the control group (P < 0.001). The SAS score, SDS score, and Pittsburgh Sleep Quality Index score after management in group A were lower than those in group B and the control group (P < 0.001). Group A had a higher 6-Minute Walk Distance than group B and the control group (P < 0.001). Group A had a higher satisfaction degree after management compared to group B (P < 0.01) and the control group (P < 0.001). Group A had lower noise level than group B and the control group (P < 0.001), and there was no significant difference in noise level between group B and the control group (P > 0.05).

CONCLUSION

Ward-noise reduction management combined with MTP management mode can reduce the noise level in the ward and improve the psychological state and sleep quality of patients with heart failure.

Different nursing interventions on sleep quality among critically ill patients: A systematic review and network meta-analysis

BACKGROUND

Critically ill patients in intensive care often struggle with disrupted sleep, a prevalent issue in this population. However, the question of which non-pharmacological intervention is most effective in enhancing sleep quality remains unanswered. This study was conducted to comprehensively evaluate and compare the efficacy of various non-pharmacological interventions aimed at improving sleep quality among critically ill individuals.

METHODS

We conducted a search of PubMed, Embase, and the Cochrane Library (Cochrane Central Register of Controlled Trials) without language restrictions to identify articles published until July 15, 2023. Randomized controlled trials (RCTs) that investigated various nursing interventions designed to improve sleep quality in critically ill patients were included in this network meta-analysis. All analyses were performed using R software (version 3.4.3) with the "gemtc" package.

RESULTS

A total of 2036 patients from 31 RCTs were included in the network meta-analysis, involving 11 different nursing interventions (routine care, relaxation combined with imagery (RI), nursel, music + earplugs + eye masks, music, eye masks, earplugs + eye masks, earplugs, aromatherapy, Warm footbath combined with acupoint exercise (WFA), Virtual reality meditation (VR)). Eye masks and earplugs + eye masks were associated with improved sleep quality compared to routine care intervention (P < .05).

CONCLUSIONS

In summary, eye masks and earplugs + eye masks stand out as the most effective interventions for enhancing sleep quality in critically ill patients. Therefore, critical care nurses should consider incorporating the use of eye masks alone or combining music with eye masks into the sleep care regimen for critically ill patients.

Hospital Environmental Disruptors and Caregiver Sleep During Hospitalization

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.

Application of Noise Control Combined with Relaxation Training in Patients with Skin Laser Cosmetology: A Single-center Retrospective Study

Objective

Noise pollution has been listed as one of the three major types of pollution, along with air and water pollution. Hospitals should pay attention to noise control, which is of great importance for the treatment and rehabilitation of patients. This study focuses on the application value of noise control and relaxation training.

Methods

This study retrospectively collected and analyzed the clinical data of 184 patients who underwent skin laser cosmetology in Ningbo Yinzhou No. 2 Hospital from January 2021 to December 2022. Twelve patients who did not meet the criteria were excluded, and the remaining 172 patients were divided based on the type of intervention into the control group (CG, n = 82) and the study group (SG, n = 90). The CG received relaxation training and routine noise management, while the SG received noise control combined with relaxation training. The intervention effect was discussed from the aspects of noise, psychology, and satisfaction.

Results

After the intervention, the SG had overtly lower noise levels and lower scores of anxiety and depression compared to the CG (all P < 0.001). Correlation analysis showed that noise levels were positively correlated with scores of anxiety and depression (r = 0.553, r = 0.592, P < 0.001). The two groups had no significant difference in total satisfaction (P > 0.05).

Conclusion

Noise poses a significant threat to the human body. Strengthening noise control in hospitals is beneficial for patients' recovery. Combining noise control with relaxation training is an intervention method worthy of clinical application. It can improve the hospitalization environment and reduce the noise levels to a great extent, thereby improving the psychological state of patients and enhancing the medical satisfaction.

The effectiveness of non-pharmacological sleep interventions for improving inpatient sleep in hospital: A systematic review and meta-analysis

BACKGROUND

Sleep disturbance is common in hospital. The hospital environment can have a negative impact on sleep quality, through factors such as noise, light, temperature, and nursing care disruptions. Poor sleep can lead to delays in recovery, wound healing, and increase risk of post-operative infection.

METHODS

We conducted a systematic review evaluating the effectiveness of non-pharmacological sleep interventions for improving inpatient sleep. The primary outcome was sleep quality, the secondary outcome was length of hospital stay, the harm outcome was adverse events. MEDLINE, Embase, CINAHL, PsycINFO and the Cochrane Library were searched from inception to 17^th February 2022. Meta-analysis was conducted using a fixed effects model, with narrative synthesis for studies with no useable data. Risk of bias was assessed with the Cochrane tool.

RESULTS

76 studies identified with 5375 people randomised comparing 85 interventions. Interventions focused on physical sleep aids (n = 26), relaxation (n = 25), manual therapy (n = 12), music (n = 9), psychological therapy (n = 5), light therapy (n = 3), sleep protocols (n = 2), milk and honey (n = 1), exercise (n = 1), and nursing care (n = 1). In meta-analysis, medium to large improvements in sleep quality were noted for sleep aids, relaxation, music, and manual therapies. Results were generally consistent in studies at lower risk of bias. Length of hospital stay and adverse events were reported for some studies, with benefit in some trials but this was not consistent across all interventions.

CONCLUSIONS

Physical sleep aids, relaxation, manual therapy and music interventions have a strong evidence base for improving inpatient sleep quality. Research is needed to evaluate how to optimise interventions into routine care.

Assessment of Self-Reported Factors Associated With Impaired Sleep in Hospitalized Adult Patients in Internal Medicine

Objectives

To evaluate the different personal, environmental, and social factors associated with the impaired sleep of patients who were admitted for treatment in the department of internal medicine in a tertiary care hospital in Azad Kashmir.

Material and methods

A single-center, exploratory, prospective study was conducted at Abbas Institute of Medical Sciences (AIMS), a public sector teaching hospital of Azad Jammu and Kashmir Medical College, Muzaffarabad, between November 2021 and January 2022. A standard Performa was used to collect and document the demographic information, the duration and quality of sleep at home and after admission to the hospital. The patients were asked to identify and report the most important factors contributing to disturbed sleep in the hospital. Statistical analysis was performed using SPSS version 23.0 (SPSS Inc., Chicago, IL, USA), continuous parametric variables were reported as mean ± standard deviation; nonparametric continuous variables were reported as median; and categorical variables were expressed as percentages. Exploratory factor analysis was performed and principal components were extracted.

Results

As reported by the patients, the main factors contributing to disturbed sleep were underlying medical conditions, noise, overcrowding and gathering of people, pain, fever, lighting, weather conditions, and medical interventions. Exploratory component factor analysis showed significant loading of overcrowding and lighting in the ward on components 1 and 2. Component 3 was loaded with underlying illness, noise, pain and fever, uncomfortable mattress, and treatment interventions by the medical staff.

Conclusions

There were many personal and environmental factors, which contributed towards impaired sleep in hospitalized patients. The underlying medical conditions, noise, overcrowding, lighting, pain and fever, are the most commonly reported factors by hospitalized patients.

Sleep improvement intervention and its effect on patients' sleep on the ward

AIM AND OBJECTIVE

The aim of the study was to investigate how the sleep improvement interventions developed for the wards were associated with patients' sleep. The objective was to promote patients' sleep.

BACKGROUND

The quality of sleep is vital for patients' health and recovery from illness. However, patients generally sleep poorly during hospitalisation. Sleep-disturbing factors are connected to the hospital environment, patients' physical illness, emotional state and the activities of the staff. Many sleep-disturbing factors can be influenced by appropriate nursing interventions.

DESIGN

A two-group intervention study including the development of nursing interventions aimed at supporting patients' sleep. One group received a sleep promotion intervention and the other received standard care. Both groups evaluated their sleep in the morning.

METHODS

A survey of participants' sleep evaluations was collected with the five-item Richards-Campbell Sleep Questionnaire. The data were analysed statistically. The STROBE checklist was used to report the study.

RESULTS

From the participants' perspective, sleep was better in the intervention group, even though statistically significantly only among men. The pain intensity correlated with sleep quality. The number of patients in the room or whether participants had had an operation had no effect on their sleep evaluations.

CONCLUSIONS

Interventions targeted at supporting and promoting the sleep quality of hospital inpatients may be effective. They should be developed in collaboration with patients and nurses. Several nursing interventions can be proposed to promote better sleep among patients; however, more research is needed to confirm the results. Sleep promotion should include both standardised protocols and individualised sleep support.

RELEVANCE TO CLINICAL PRACTICE

Investing in nursing interventions to promote patients' sleep is important. Patients' individual sleep-related needs should be part of their care plan. Training programmes that support nurses' knowledge and skills of patients' sleep promotion should be part of nursing education in healthcare organisations.

Family satisfaction in a neuro trauma ICU

OBJECTIVE

The purpose of this quality improvement initiative was to evaluate satisfaction of family members of patients in a neuro trauma ICU (NTICU).

METHODS

Adult patients (age 18+) admitted to the NTICU for at least 24 hours between June 2017 and November 2018 were identified. Near or at the time of discharge from the NTICU, the health unit coordinator or registered nurse identified the family member who was either the next-of-kin, surrogate decision-maker, or person who had been most frequently present at the patient's bedside. This person was provided a packet containing a letter of consent and the Critical Care Family Satisfaction Survey (CCFSS).

RESULTS

Surveys were completed by 78 family members, the majority of whom were the wife of the patient (n = 35, 44%), 60 years and older (n = 48, 60.8%). Fifty-seven percent of patients (n = 45) were in the ICU less than 3 days and 59% (n = 47) of medical events were injury-related. Total CCFSS scores ranged from 69 to 100 (median 95). The item with the largest number of dissatisfied responses was "Noise level in the critical care unit" (n = 4, 5.3% not satisfied). Open-ended question comments were primarily positive (n = 60, 66%), with 32% (n = 29) representing areas for improvement.

CONCLUSIONS

Results of this satisfaction survey have been disseminated to leadership and have been taken into consideration in the planning of a new hospital building currently being built, including ICU patient rooms that allow for more privacy and reduced noise, and more comfortable family rooms.

RELEVANCE TO CLINICAL PRACTICE

Family members are a very useful source of feedback for ICU care. Several concerns identified by family members in this study are likely to be relevant to other sites. These included: communication between health care providers and family about patient status, noise in the ICU, peaceful waiting areas for family, and slow transfers.
