Timing and Duration of Sleep in Hospitalized Children: An Observational Study

Sleep disturbances in hospitalized children: a wake-up call

Although sleep is essential for (recovery of) health, it is adversely affected by hospitalization, due to disease discomfort, environmental noise, and care routines, causing reduced sleep and increased disturbances. This study evaluates factors affecting sleep quality and quantity in hospitalized children and compares inpatient sleep with sleep at home. Using an observational, prospective study design, we assessed sleep in hospitalized children aged 1-12 years, admitted to a tertiary center, and compared this with home 6-8 weeks after discharge. We measured total sleep time (TST), sleep onset latency (SOL), wake after sleep onset (WASO), sleep efficiency, awakenings, and subjective sleep quality, using actigraphy, sleep diaries, and PROMIS questionnaires. We explored an array of sleep-disturbing factors. Regression analyses identified key determinants affecting sleep patterns, while mixed linear models compared sleep in hospital to sleep at home. Out of 621 eligible patients, 467 were invited, and 272 (58%) consented to participate. Key determinants of sleep included pain, number of previous admissions, (underlying) chronic illness, and environment-, staff-, and disease-related factors. Parents reported lower perceived sleep quality in the hospital compared to at home, 97-min (SE 9) lower TST, 100-min (5) longer WASO, more difficulties with falling asleep, lower sleep satisfaction, and more awakenings. Actigraphy outcomes revealed shorter TST (20 min (6)), but better sleep efficiency and fewer awakenings in the hospital. Conclusion: Sleep in hospital was compromised in comparison to sleep at home, primarily due to disturbances related to treatment, environment, and staff. These findings underscore the necessity and potential of relative simple interventions to improve sleep quality and minimize sleep disturbances in hospitalized children.

Prevalence and Correlates of Sleep Disorders Among Pediatric Inpatients in a Tertiary Pediatric Hospital

Background It is possible to define sleep disorders as any disturbance in sleep timing, quality, or quantity that results in daytime distress and impairment in functioning that, in turn, affects the baseline functional status of an individual. Our study aimed to describe how sleep disorders might affect pediatric inpatients at King Abdulaziz University Hospital (KAUH) as well as estimate their prevalence (2021-2022). We assessed the sleep habits using questionnaires and analyzed and combined these data to create rankings to compare the different issues affecting sleep habits in pediatric patients. Methodology Two scoring systems were used in this study, namely (a) the Children's Sleep Habits Questionnaire (CSHQ) and (b) the Pediatric Sleep Questionnaire. Analyses of the data were conducted using SPSS version 23 (IBM Corp., Armonk, NY, USA) and GraphPad Prism version 8 (GraphPad Software, Inc., San Diego, CA, USA). Results The prevalence of sleep disorders and their correlations were evaluated among 98 pediatric inpatients at KAUH, Saudi Arabia, between 2021 and 2022. The average duration of hospital stay was 11.97 ± 11.0 days (N = 78), and the average number of previous admissions was 2.85 ± 3.7 (N = 93). Conclusions According to the sleep behavior domain of the CSHQ, most children woke up sweating, screaming, and inconsolable during the night. Furthermore, bedtime resistance and sleep anxiety were the most prevalent sleep disturbances observed in the study population.

Interventions Associated With Increased Nighttime Room Entries in General Medical Patients

BACKGROUND AND OBJECTIVES

Sleep is vital to recovery from illness, yet it is frequently interrupted in the hospital setting. Existing literature relying on survey data identifies vitals, medications, and pulse oximetry as major disruptors to sleep. This study was designed to assess the degree to which these candidate sleep disruptors are associated with objective room entries.

METHODS

Room entry sensors were placed on doors to 18 rooms on acute medical-surgical units at a tertiary academic center. The number of entries into rooms between 10 Pm and 6 Am were logged on patients admitted to hospital medicine services from March 2021 through February 2022. Medical records were reviewed to extract orders for vital sign frequency, medication timing, continuous pulse oximetry, and intravenous fluid use overnight. Negative binomial regression was used to evaluate associations.

RESULTS

Room entry data were collected for 112 admissions and 192 patient-nights. There was an average of 7.8 room entries per patient-night. After adjustments for the other variables and for patients represented in multiple nights, vitals ordered every 4 hours were associated with a 1.3-fold increase in room entries (95% confidence interval 1.0-1.5; P = .013), as were medications scheduled during overnight hours (1.3; 95% confidence interval 1.0-1.5; P = .016). There was no association between room entries and continuous pulse oximetry use. After adjustment, there was also no association with administration of intravenous fluids.

CONCLUSIONS

Vitals ordered every 4 hours and medications scheduled during sleep hours are independently associated with increased room entries and may be reasonable initial targets for quality improvement interventions designed to minimize nighttime disruptions.

Sleep in hospitalized pediatric and adult patients - A systematic review and meta-analysis

Background

Sleep is essential for recovery from illness. As a result, researchers have shown a growing interest in the sleep of hospitalized patients. Although many studies have been conducted over the past years, an up to date systematic review of the results is missing.

Objective

The objective of this systematic review was to assess sleep quality and quantity of hospitalized patients and sleep disturbing factors.

Methods

A systematic literature search was conducted within four scientific databases. The search focused on synonyms of 'sleep' and 'hospitalization'. Papers written in English or Dutch from inception to April 25th,2022 were included for hospitalized patients >1 year of age. Papers exclusively reporting about patients receiving palliative, obstetric or psychiatric care were excluded, as well as patients in rehabilitation and intensive care settings, and long-term hospitalized geriatric patients. This review was performed in accordance with the PRISMA guidelines.

Results

Out of 542 full text studies assessed for eligibility, 203 were included, describing sleep quality and/or quantity of 17,964 patients. The median sample size of the studies was 51 patients (IQR 67, range 6-1472). An exploratory meta-analysis of the Total Sleep Time showed an average of 7.2 h (95%-CI 4.3, 10.2) in hospitalized children, 5.7 h (95%-CI 4.8, 6.7) in adults and 5.8 h (95%-CI 5.3, 6.4) in older patients (>60y). In addition, a meta-analysis of the Wake After Sleep Onset (WASO) showed a combined high average of 1.8 h (95%-CI 0.7, 2.9). Overall sleep quality was poor, also due to nocturnal awakenings. The most frequently cited external factors for poor sleep were noise and number of patients in the room. Among the variety of internal/disease-related factors, pain and anxiety were most frequently mentioned to be associated with poor sleep.

Conclusion

Of all studies, 76% reported poor sleep quality and insufficient sleep duration in hospitalized patients. Children sleep on average 0.7-3.8 h less in the hospital than recommended. Hospitalized adults sleep 1.3-3.2 h less than recommended for healthy people. This underscores the need for interventions to improve sleep during hospitalization to support recovery.

Effect of illuminated musical mobile on sleep quality of children hospitalized in pediatric emergency departments

PURPOSE

The aim of this study is to evaluate the effect of an illuminated musical mobile on the sleep quality of children hospitalized in a pediatric emergency department.

DESIGN AND METHODS

In this randomized controlled study, 124 children presenting to a pediatric emergency department who met the inclusion criteria were included in the study. Patients were randomized into two equal groups. In the intervention group, an illuminated musical mobile was used to help facilitate sleep. In the control group, routine sleep routines were continued. Groups were compared according to sleep quality as evaluated by mothers' observations. Evaluation was performed twice (before intervention - 1st day of hospitalization and on the intervention day - 2nd day of hospitalization).

RESULTS

Average age of children was 1.86 ± 0.78 years. On the intervention day, nighttime sleep duration was longer in the intervention group (p < .0001). Also, the frequency of spontaneous awakening (p < .0001), time to fall asleep after spontaneous awakening (p < .0001) and sleep time problems (p < .0001) were less in the intervention group. CONCLUSıONS: An illuminated musical mobile was used for the first time in the pediatric emergency department and was found to be effective in improving the sleep quality of hospitalized children aged between 1 and 3 years.

PRACTICE IMPLICATIONS

During hospitalization, children's sleep quality can be increased by using methods and objects suitable for the child's developmental level.

A systematic review and proposed conceptual model of sleep disturbances during pediatric hospitalizations

STUDY OBJECTIVES

The current review aims to examine factors that influence pediatric inpatient sleep and determine the effectiveness of sleep promotion interventions among hospitalized children.

METHODS

A systematic literature search was conducted across PubMed, PsycINFO, CINAHL, Cochrane Central, Web of Science, Embase, and Scopus databases. Studies included children with a mean age between 1 and 18 years old that either described factors affecting the sleep of children who are hospitalized on a non-intensive care unit or reported on sleep-related intervention outcomes. We conducted separate narrative reviews for each of the two aims and then synthesized findings from quantitative and qualitative studies across both aims.

RESULTS

Forty-five articles were included for review. Despite most sleep disturbances being attributed to environmental disruptions (e.g. noise, staff interruptions), most interventions targeted the child level using relaxation techniques. Although the majority of interventions were small pilot studies, preliminary findings appear to positively impact sleep duration. The Pediatric Inpatient Sleep Model was proposed to illustrate connections between sleep disturbances, factors influencing sleep, and existing intervention components.

CONCLUSIONS

Replication studies are needed, including larger-scale sleep promotion interventions among hospitalized children. Given the identification of environmental factors as the main cause of night wakings, environmental modifications are crucial. Additional research examining contributors to intraindividual variability in disrupted sleep patterns during hospitalizations as well as the consequences of these disturbances is warranted.

"Help Me Sleep": A Quality Initiative to Reduce Overnight Vital Signs

BACKGROUND AND OBJECTIVES

Sleep is an essential part of the recovery process, yet inpatient sleep quality is poor. Patients and families report that vital signs are the most bothersome overnight disruption. Obtaining vital signs every 4 hours (Q4H) is not evidence-based and is frequently ordered indiscriminately. We aimed to decrease the percentage of patient nights with vital sign checks between 12 am and 6 am in a low-risk population from 98% to 70% within 12 months to minimize overnight sleep disruptions and improve inpatient sleep.

METHODS

We conducted a quality improvement project on 3 pediatric hospital medicine teams at a large free-standing children's hospital. Our multidisciplinary team defined low-risk patients as those admitted for hyperbilirubinemia and failure to thrive. Interventions were focused around education, electronic health record decision support, and patient safety. The outcome measure was the percentage of patient nights without a vital sign measurement between 12 am and 6 am and was analyzed by using statistical process control charts. Our process measure was the use of an appropriate vital sign order. Balancing measures included adverse patient events, specifically code blues outside the ICU and emergent transfers.

RESULTS

From March 2020 to April 2021, our pediatric hospital medicine (PHM) services admitted 449 low-risk patients for a total of 1550 inpatient nights. The percentage of patient nights with overnight vital signs decreased from 98% to 38%. There were no code blues or emergent transfers.

CONCLUSION

Our improvement interventions reduced the frequency of overnight vital sign monitoring in 2 low-risk groups without any adverse events.

Sleep disturbance and psychological distress among hospitalized children in India: Parental perceptions on pediatric inpatient experiences

PURPOSE

Investigate parental perceptions of children's sleep disturbance and psychological distress associated with an inpatient stay in a low-resource hospital setting.

DESIGN AND METHODS

Demographic and validated survey instruments were adapted for administration to parents of children in the medical wards of a tertiary hospital in India. Parents proficient in English, Hindi, Tamil, or Telugu with a child age 4-12 years admitted for at least 48 h were eligible to participate. All respondents completed the Factors Affecting Sleep Disturbance Scale, Sleep Duration Questionnaire, Sleep Disturbance Scale, and Kessler Psychological Distress Scale. Data analysis entailed descriptive statistics, correlations, and multivariate regressions to analyze relationships across responses on demographics, sleep disturbance, and psychological distress.

RESULTS

Among 105 parents with hospitalized children, most had children 4-6 years old (54%), including 65% boys and 35% girls. Parents reported that their children slept overnight in the hospital for a mean of 8.3 ± 1.6 h. Children 4-6 year old (relative risk ratio [RRR] = 0.63, p = .004), dyspnea (RRR = 8.73, p = .04), previous hospitalization (RRR = 9.17, p = .03), nighttime procedures (RRR = 2.97, p = .03, and missing home (RRR = 6.78, p < .001) were the factors affecting sleep. Factors affecting psychological distress was nighttime medication administration (RRR = 4.92, p = .01). Sleep disturbances correlated with psychological distress (r = 0.56; p < .01).

CONCLUSION

Sleep disturbance and associated psychological distress in hospitalized children were widely reported by parents queried in this low-resource hospital setting.

PRACTICAL IMPLICATIONS

Nurses can lead efforts in ameliorating sleep in hospitalized children, including partnering with stakeholders on measures to reduce sleep disruption. Child-centered interventions may improve sleep hygiene and decrease psychological distress among children.

Prevalence of Sleep Disturbances in Pediatric Cancer Patients and Their Diagnosis and Management

Sleep disturbances represent an understudied yet common source of distress among pediatric cancer patients and survivors, with deleterious effects on quality of life. Sleep issues stem from multiple risk factors, yet individual contributors are difficult to isolate, consequently impeding the identification of targets for intervention. In many pediatric cancer patients, disrupted sleep and its negative impact on quality of life continue into adulthood and may affect various functional domains. This literature review highlights the types and prevalence of sleep disturbances in pediatric cancer patients during active treatment and through survivorship. Potential etiological and risk factors for disturbed sleep are summarized, including the effects of cancer and its treatment, psychosocial and family factors, as well as individual-patient aspects, such as genetics, mood and coping skills. While existing assessment and management strategies are reviewed, the literature is incomplete, and significant gaps emerge in our understanding of sleep disturbances in pediatric cancer patients and survivors. The review concludes with recommendations of areas where further research is needed. The aims of this review include increasing clinicians' awareness of sleep disturbances as a significant source of poor quality of life in pediatric cancer patients and survivors and directing researchers to gaps in our understanding of sleep disturbances in pediatric cancer patients and survivors.

Sleep in hospitalized children and adolescents: A scoping review

Hospitalized children and adolescents are at risk of short sleep and subsequent adverse health effects, but little is known about actual sleep duration, the factors that cause sleep disturbances in an inpatient pediatric setting, and what has been done to promote sleep in this population. The aim of this review was to systematically identify, categorize, and synthesize the literature on sleep in children and adolescents in an inpatient setting. We searched five electronic databases (PubMed, CENTRAL, CINAHL, PsycINFO, and Scopus) and of the 3770 references identified, 28 were eligible for inclusion. From studies reporting age-specific sleep durations, we found that four out of nineteen fell within the National Sleep Foundations recommendations for age-specific sleep durations. Reported causes of sleep disturbances were primarily related to modifiable, external factors, e.g., nursing care activities and noise from equipment and other patients. Sleep-promoting interventions seemed acceptable to patients, parents, and healthcare professionals. However, the literature in this area is heterogeneous regarding methodology, reporting, and population characteristics. Our findings underline the importance of prioritizing and optimizing sleep in hospitalized pediatric patients and highlight the need for standardization in the planning and reporting of studies within this field.

Objective Sleep Characteristics and Factors Associated With Sleep Duration and Waking During Pediatric Hospitalization

IMPORTANCE

Children's sleep may be affected by hospitalization, yet few objective determinations of sleep patterns are reported for children in intensive care or general medicine units. There is limited research on relationships between sleep in hospital and child (eg, age, pain), treatment (eg, medications, nurse presence), or environmental (eg, noise, light, type of unit) factors.

OBJECTIVE

To determine sleep quantity and patterns in hospitalized children and determine factors associated with sleep quantity and nighttime waking for children in hospital.

DESIGN, SETTING, AND PARTICIPANTS

This was a prospective cross-sectional study of children admitted to a general pediatric unit or a pediatric intensive care unit at a pediatric quaternary teaching hospital in Toronto, Ontario, Canada, from October 2007 to July 2008. Participants included children aged 1 to 18 years who were expected to stay in hospital for at least 2 nights. Demographic data, information about the hospital stay and illness, and usual sleep habits were collected. Children wore an actigraph for 1 to 3 consecutive days and nights and completed a sleep diary. Sound and light meters were placed at the bedside. Data analyses took place in April 2009.

MAIN OUTCOMES AND MEASURES

The primary outcome was the mean number of minutes of child nighttime sleep from 7:30 pm to 7:29 am. Sleep variables were averaged over days and nights recorded (mean [SD] days and nights of wear, 2.54 [0.71]) and examined for associations with sleep quantity and patterns, as well as hazard of waking in the night.

RESULTS

Of 124 eligible children approached for inclusion, 69 children consented (35 [51%] female; 20 [29%] aged 1-3 years, 10 [14%] aged 4-7 years, 17 [24%] aged 8-12 years, and 22 [32%] aged 13-18 years; 58 [84%] in the general pediatric unit). Children aged 1 to 3, 4 to 7, 8 to 12, and 13 to 18 years obtained a mean (SD) of 444 (132), 475 (86), 436 (114), and 384 (83) minutes of nighttime sleep, respectively; mean (SD) number of night awakenings was 14 (3), 18 (3), 14 (8), and 12 (6), respectively. Children on general pediatric units slept 258 minutes more per night than children sleeping in the pediatric intensive care unit (95% CI, 165.16-350.56 minutes; P < .001), children admitted for planned surgery slept 123 minutes more than children admitted for exacerbations of chronic illness (95% CI, 49.23-196.01 minutes; P < .01), and children sleeping in rooms with other patients slept 141 minutes fewer than children in private rooms (95% CI, -253.51 to -28.35 minutes; P = .01). Sound events greater than 80 dB were significantly associated with increased risk of instantaneous waking (hazard ratio [HR], 1.35; 95% CI, 1.02-1.80; P = .04), as were light events greater than 150 lux (HR, 1.17; 95% CI, 1.01-1.36; P = .03), receiving a medication that promoted sleep (HR, 1.04; 95% CI, 1.00-1.08; P = .03), and having a nurse in the room for most or all of the night (HR, 1.08; 95% CI, 1.03-1.13; P = .003). Sleeping on the general pediatrics unit was significantly associated with decreased risk of instantaneous waking (HR, 0.81; 95% CI, 0.77-0.85; P < .001), as was being admitted for planned surgery (HR, 0.95; 95% CI, 0.91-0.99; P = .04), receiving a medication that promoted wakefulness (HR, 0.96; 95% CI, 0.93-0.995; P = .02), and sharing a room with another patient (HR, 0.78; 95% CI, 0.72-0.84; P < .001).

CONCLUSIONS AND RELEVANCE

In this cross-sectional study of hospitalized children, children experienced considerable nighttime waking and sleep restriction to levels below national clinical recommendations at a time when they most needed the benefits of sleep. Given light and noise were the greatest contributors to nighttime waking in hospital, clinicians, administrators and hospital design experts should work together for solutions.
