Promoting sleep by nursing interventions in health care settings: a systematic review

Evaluating the effect of preoperative interventions on sleep health in the perioperative period: a systematic review

Surgery and general anaesthesia have deleterious effects on sleep and disrupted perioperative sleep health is a risk factor for poor surgical outcomes. The objective of this systematic review was to summarise preoperative interventions that report sleep outcomes. Studies that delivered an intervention initiated >24 h prior to surgery among an adult sample without a diagnosed sleep disorder were included. Studies were excluded if they were preclinical or were not published in English. MEDLINE, MEDLINE ePubs Ahead of Print and In-process Citations, Embase, Cochrane Central Register of Controlled Trials, APA PsycINFO, CINAHL, and the Web of Science were searched on February 2, 2023. This review was reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses and was registered with the International Prospective Register of Systematic Reviews (identifier: CRD42021260578). Risk of bias was assessed using the Cochrane Risk-of Bias 2 tool for randomised trials and the Risk Of Bias In Non-randomised Studies - of Interventions for non-randomised trials. Certainty of findings were assessed using the Grading of Recommendations, Assessment, Development and Evaluation framework. The searching yielded 10,938 total citations, and after screening resulted in 28 randomised and 19 non-randomised trials (47 total) with 4937 participants. Sleep was a primary outcome in 16 trials; a sleep outcome was significantly improved relative to comparator in 23 trials. This review demonstrates that preoperative sleep is modifiable via a variety of interventions, including pharmacological, non-pharmacological, and nursing interventions delivered preoperatively or perioperatively. Our results should be considered with caution due to an overall intermediate to high risk of bias in the included trials, and low to very low certainty of evidence. This review supports the modifiability of sleep health among surgical patients and provides the groundwork for preoperative sleep optimisation research.

Insomnia in the Veteran Population: A Sleep Health and Wellness Intervention

The purpose of this evidence-based project (EBP) was to determine if an evidence-based sleep health and wellness intervention improved sleep in veterans self-reporting a history of insomnia. Insomnia can negatively affect an individual's physical and psychological well-being, as well as increase health-care costs and decrease the overall quality of life. The intervention utilized a combination of insomnia treatments, delivered to two American Legion veteran participant groups: an Alabama American Legion Retreat and individuals at an American Legion Post site. The holistic-focused modalities used in this intervention included Cognitive Behavioral Therapy for Insomnia (CBT-I) techniques, sleep hygiene principles, and Complementary and Alternative Medicine (CAM) methods. The measurement tool, the Insomnia Severity Index (ISI), indicated statistically significant changes in the severity of participants' self-reported insomnia. Based upon the research evidence and results of the pre- and post-test ISI, a more permanent, ongoing sleep health and wellness intervention is feasible and would have numerous beneficial effects for the veteran's management of insomnia symptoms. Future efforts include implementing sleep hygiene, CAM interventions, and holistic nursing-supported education interventions at other sites and venues within the Alabama American Legion, as well as maintaining long-term community partnerships with veteran groups such as the Alabama American Legion.

The Effectiveness of a Multi-Sensory Sleep-Promotion Program on Sleep Quality among Hospitalized Older Adults of Thailand: A Quasi-Experimental Study

BACKGROUND/OBJECTIVE

Older adults suffer from sleep disturbances, especially during hospitalization, affecting their health condition, recovery, and in-hospital mortality. Therefore, we aimed to explore the effectiveness of a multi-sensory sleep-promotion program on sleep quality among hospitalized Thai older adults.

METHODS

In a quasi-experimental study, the 52 eligible older adults in a private medical ward were equally assigned into two groups. The experimental group received a sleep quality assessment after the first night of admission, the 60-minute multi-sensory sleep-promotion program for three nights, and an outcome evaluation on the last night after the intervention. In contrast, the control group received routine care for the same period. Sleep quality was measured by the Verran and Snyder-Halpern Sleep Scale (Thai version). In addition, independent and paired samples t-tests compared the sleep quality between and within the two groups.

RESULTS

The older adults in the experimental group had better sleep quality than those who did not (p < .001). Those who participated in the multi-sensory sleep-promotion program markedly improved their sleep quality over five days (p < .001).

CONCLUSION

A multi-sensory sleep-promotion program can promote the sleep quality of older adults. The five alternative methods to promote sleep are effective without the deleterious effects of hypnotics and sedatives often experienced among older adults. Therefore, nurses and other healthcare professionals can implement this program as standard practice. In addition, they may adjust it to fit the acuity level and care dependencies of older adults in other cultures to promote sleep quality.

Development of a multi-component intervention to promote sleep in older persons with dementia transitioning from hospital to home

BACKGROUND

Hospitalised older persons with dementia are commonly discharged with intensified sleep disturbances. These disturbances can impede the recovery process. Nurses are well-positioned to assist persons with dementia and their family caregivers in managing sleep disturbances during the transition from hospital to home.

OBJECTIVES

To describe the development of a multi-component intervention to promote sleep.

METHODS

We applied three stages of the intervention mapping method to develop a non-pharmacological, multi-component sleep intervention. The first stage involved a review of the literature to generate an understanding of the determinants of sleep disturbances experienced by persons with dementia in hospital and home settings. The second stage consisted of a literature review to identify therapies for managing commonly reported determinants of sleep disturbances. The third stage entailed delineation of the intervention components.

RESULTS

The most common determinants of sleep disturbances experienced by persons with dementia in hospital and home settings were: physiological changes associated with ageing, sleep environments non-conducive to sleep, limited exposure to light and engagement in physical activity, stress and sleep-related beliefs and behaviours. Therapies found effective included: light therapy, physical activity therapy, sleep hygiene, and stimulus control therapy. These therapies were integrated into a multi-component sleep intervention to be provided using the teach-back technique, during and following hospitalisation.

DISCUSSION

Consistent with the principles of patient engagement, the multi-component sleep intervention will be evaluated for its acceptability and feasibility.

IMPLICATIONS FOR PRACTICE

The intervention has potentials to improve sleep during the transition from hospital to home.

Effects of nursing interventions to improve inpatients' sleep in intensive and non-intensive care units: Findings from an umbrella review

AIM

This review aimed to synthesise the available reviews on the effects of nursing interventions on sleep quality among patients hospitalised in intensive care and non-intensive care units.

BACKGROUND

Poor sleep quality is a common fact in hospitalised patients. Nurses can contribute to the improvement of patients' sleep quality and duration.

DESIGN

A review of intervention reviews was carried out and reported following the PRISMA guidelines and checklist.

METHODS

We systematically searched for reviews published from January 2009 to December 2019 in PubMed, CINAHL Plus, Scopus, Institute for Scientific Information Web of Science, Joanna Briggs Database of Systematic Reviews and Cochrane Central Register of Controlled Trials databases. Searches were repeated at 24 November 2020 to include the most recent evidence. A narrative synthesis of the results was conducted.

RESULTS

Nine reviews (representing 109 original papers) met the selection criteria and were included for critical appraisal. Overall, nursing interventions and sleep quality were poorly defined. We grouped the interventions into 3 categories (environmental, barrier and internal interventions) to provide a more comprehensive overview and examine effects of nursing interventions on inpatients sleep quality. Inconsistent results were obtained and low quality of the original articles was reported, making it difficult to establish absolute conclusions.

CONCLUSION

The impact of environmental changes on patients' sleep was positive but inconclusive, while use of earplugs and eye masks, music and acupuncture generally showed positive results with moderate quality of evidence, and no harmful effects were reported.

Reducing Delirium in Hospitalized Adults Through a Structured Sleep Promotion Program

BACKGROUND

Delirium affects approximately 1 in 4 patients during their hospitalization and is associated with numerous complications. Sleep deprivation is a significant risk factor for developing delirium and is a patient dissatisfier.

PROBLEM

An internal assessment revealed that up to 25% of all patients on medical-surgical units had a diagnosis of delirium while in the hospital.

APPROACH

An evidence-based practice project was implemented to reduce the development of delirium through sleep promotion on 2 inpatient units. A dedicated time was selected, and key strategies were identified to promote sleep with minimal interruptions.

OUTCOMES

Delirium decreased by 33% and 45% on the 2 units over 1 year. Overall, patient satisfaction for quietness at night survey responses also increased (P = .0005; CI, 0.05 to 0.67) with ongoing sustainment.

CONCLUSIONS

Implementation of a dedicated period to sleep was associated with a reduction in delirium and increased patient satisfaction for quietness at night.

Optimizing hospital-to-home transitions for older persons in rural communities: a participatory, multimethod study protocol

BACKGROUND

Transitional care involves time-limited interventions focusing on the continuity of care from hospital to home, to optimize patient functioning and management. Providing interventions, as part of transitional care, that optimize the functioning of older people with dementia is critical due to the small window of opportunity in which they can return to their baseline levels of functioning. Yet prior research on transitional care has not included interventions focused on functioning and did not target older people with dementia in rural communities, limiting the applicability of transitional care to this population. Accordingly, the goal of this study is to align hospital-to-home transitional care with the function-related needs of older people with dementia and their family-caregivers in rural communities.

METHODS

In this multimethod study, two phases of activities are planned in rural Ontario and Nova Scotia. In phase I, a purposive sample of 15-20 people with dementia and 15-20 family-caregivers in each province will rate the acceptability of six evidence-based interventions and participate in semi-structured interviews to explore the interventions' acceptability and, where relevant, how to improve their acceptability. Acceptable interventions will be further examined in phase II, in which a purposive sample of healthcare providers, stratified by employment location (hospital vs. homecare) and role (clinician vs. decision-maker), will (1) rate the acceptability of the interventions and (2) participate in semi-structured focus group discussions on the facilitators and barriers to delivering the interventions, and suggestions to enable their incorporation into rural transitional care. Two to three focus groups per stratum (8-10 healthcare providers per focus group) will be held for a total of 8-12 focus groups per province. Data analysis will involve qualitative content analysis of interview and focus group discussions and descriptive statistics of intervention acceptability ratings.

DISCUSSION

Findings will (1) include a set of acceptable interventions for rural transitional care that promote older patients' functioning and family-caregivers' ability to support patients' functioning, (2) identify resources needed to incorporate the interventions into rural transitional care, and (3) provide high-quality evidence to inform new transitional care practices and policies and guide future research.

Sleep Health Promotion Interventions and Their Effectiveness: An Umbrella Review

Sleep is receiving increasing attention in public health. The aim of this umbrella review is to determine what non-pharmacological sleep health interventions have been evaluated among healthy populations, by examining target groups, settings, and effectiveness in improving sleep quality and duration. Comprehensive searches were conducted in five electronic databases (January 1975–February 2019), yielding 6505 records. Thirty-five articles were selected meeting the following eligibility criteria: (1) systematic reviews or meta-analyses of (2) sleep health interventions in (3) primarily healthy populations. Two reviewers independently screened for inclusion, extracted the data, and assessed the review quality. This umbrella review was registered with PROSPERO (CRD42019126291). Eleven intervention types were defined, and their effectiveness discussed. Substantial evidence demonstrated the effectiveness of later school start times, behavior change methods, and mind–body exercise. Other intervention types, including sleep education or relaxation techniques, demonstrated some promising impacts on sleep, but with less consistent evidence. Results were limited by high heterogeneity between studies, mixed results, and variable review quality. Nevertheless, this umbrella review is a first step towards understanding the current state of sleep health promotion and gives an overview of interventions across the lifespan.

The efficacy of nursing interventions on sleep quality in hospitalized patients: A systematic review of randomized controlled trials

OBJECTIVE

To determine the effect of interventions that could be performed by nurses to improve the sleep quality of hospitalized patients in acute and semi-acute units.

DESIGN

A systematic review of randomized controlled trials and narrative synthesis.

DATA SOURCES

Seven electronic databases (PubMed, CINAHL Plus, Scopus, ISI WoS, CENTRAL, PsycInfo, and Embase) were accessed on 20 May 2019 with a temporal limit of 10 years prior.

REVIEW METHODS

Original research studies of interventions that could be delivered by nurses to improve sleep quality during hospitalization in acute and semi-acute units were included. Study selection, data extraction, and risk of bias assessment were performed by two independent reviewers.

RESULTS

Seventeen studies met the inclusion criteria and were included in this review. The interventions carried out in the trials were classified into four categories of measurement: environmental, physical, behavioural, and combined. Fourteen studies obtained statistically significant improvements; two showed a blend of significant and non-significant improvements; and one reported non-significant results. However, only four trials of the seventeen were judged as having a low risk of bias.

CONCLUSIONS

Overall evidence about interventions that could be performed by nurses to improve perceived sleep quality in hospitalized patients was found to be positive, and no negative effects were reported. However, higher quality research using both subjective and objective measures is needed, in order to strengthen the evidence.

Relationships between nursing diagnoses and the level of dependence in activities of daily living of elderly residents

OBJECTIVE

To identify and validate nursing diagnoses of elderly residents, and determine their relationship with the level of dependence in activities of daily living.

METHODS

One hundred thirty-five older adults were assessed using medical history and physical examination. Twelve validated gerontological instruments were administered to assess delirium, nutritional status, risk for falls, risk for pressure injury, dementia, cognitive losses, depression, and level of dependence in daily living and instrumental activities of daily living. Nursing diagnoses were identified and validated by experienced, doctorally-prepared nurses. The association between the presence of a nursing diagnosis and the level of dependence was assessed by a test for trend in proportions. The Kruskal-Wallis hypothesis test was used to investigate the association between the number of nursing diagnoses and the level of dependence of the elderly.

RESULTS

Most older adults were at risk for malnutrition, at high risk for falls, cognitively impaired, totally dependent for daily living and activities of daily living. In addition, they had very mild dementia and most did not have risk for pressure injuries. Depression was noted among those with dementia, but was absent in those without dementia. A total of 52 nursing diagnoses were validated. Of these, 11 were associated with the level of dependence in daily living.

CONCLUSION

These results can be reproduced in other skilled nursing facilities for older adults, and these may allow the planning of interventions to alleviate etiologies and signs/symptoms of nursing diagnoses, rather than simply directing care toward a general category of dependence. Therefore, guaranteeing individualized nursing care to meet the specific needs of each resident.

Sleep Deprivation from the Perspective of a Patient Hospitalized in the Intensive Care Unit-Qualitative Study

(1) Introduction: Sleep architecture of Intensive Care Unit (ICU) patients is altered, with over 60% of them reporting sleep disorders or even sleep deprivation during their stay. The aim of the study was to describe the experiences related to sleep and nighttime rest of patients hospitalized in the ICU. (2) Method: the study used a qualitative project based on phenomenology as a research method. A semi-structured interview was used as the method to achieve the goal. The patients’ answers were recorded and transcribed. The data were coded and cross-processed. (3) Results: twenty-three patients were surveyed, fifteen men and eight women. The average age was 49.7 years. The average time of hospitalization was 34.3 days. During the ICU stay, patients required mechanical ventilation through the tracheostomy tube. Five themes were identified from the interview as factors disturbing sleep: fear, noise, light, medical staff, and at home best. (4) Conclusions: chronic anxiety appears to contribute to sleep disturbances in the ICUs, psychological support, and individualized approach to the hospitalized patient seem necessary. By raising the awareness of the essence of sleep among medical staff, environmental factors can be reduced as disturbing sleep. Based on the participants’ comments, it is possible that repeated actions could also increase the patients’ sense of security.

Comparative effectiveness and safety of pharmacological and non-pharmacological interventions for insomnia: an overview of reviews

BACKGROUND

This review aimed to assess the existing evidence regarding the clinical effectiveness and safety of pharmacological and non-pharmacological interventions in adults with insomnia and identify where research or policy development is needed.

METHODS

MEDLINE, Embase, PsycINFO, The Cochrane Library, and PubMed were searched from inception until June 14, 2017, along with relevant gray literature sites. Two reviewers independently screened titles/abstracts and full-text articles, and a single reviewer with an independent verifier completed charting, data abstraction, and quality appraisal.

RESULTS

A total of 64 systematic reviews (35 with meta-analysis) were included after screening 5024 titles and abstracts and 525 full-text articles. Eight of the included reviews were rated as high quality using the Assessment of Multiple Systematic Reviews 2 (AMSTAR2) tool, and over half of the included articles (n = 40) were rated as low or critically low quality. Consistent evidence of effectiveness across multiple outcomes based on more than one high- or moderate quality review with meta-analysis was found for zolpidem, suvorexant, doxepin, melatonin, and cognitive behavioral therapy (CBT), and evidence of effectiveness across multiple outcomes based on one high-quality review with meta-analysis was found for temazepam, triazolam, zopiclone, trazodone, and behavioral interventions. These interventions were mostly evaluated in the short term (< 16 weeks), and there was very little harms data available for the pharmacological interventions making it difficult to evaluate their risk-benefit ratio.

CONCLUSIONS

Assuming non-pharmacological interventions are preferable from a safety perspective CBT can be considered an effective first-line therapy for adults with insomnia followed by other behavioral interventions. Short courses of pharmacological interventions can be supplements to CBT or behavioral therapy; however, no evidence regarding the appropriate duration of pharmacological therapy is available from these reviews.

Safety of implementing a sleep protocol in hospitalized patients

BACKGROUND

Although good sleep during hospitalization may promote positive outcomes, some patients and clinicians may have concerns about nursing interventions designed to reduce night-time sleep disturbances.

METHODS

A randomized prospective trial of an intervention to promote sleep was conducted with stable, post-operative oncology patients. Eligible patients were randomized to receive usual nursing care overnight or sleep-promoting interventions.

RESULTS

All thirty-seven surgeons in the organization agreed to let their qualified patients participate. One hundred and forty-four patients met the study criteria. Of those, 117 (81%) consented to participate, while 27 (19%) declined. The primary reason for non-enrollment was wanting to be checked on throughout the night (n = 21, 78%). There were no adverse events during the study period. Patients' perceptions of pain and nausea control among the two groups were equivalent.

CONCLUSION

An intervention to decrease sleep disturbances can be safely executed in a post-operative population while maintaining adequate symptom management.

Outcomes of Patient- and Family-Centered Care Interventions in the ICU: A Systematic Review and Meta-Analysis

OBJECTIVE

To determine whether patient- and family-centered care interventions in the ICU improve outcomes.

DATA SOURCES

We searched MEDLINE, EMBASE, PsycINFO, CINAHL, and the Cochrane Library databases from inception until December 1, 2016.

STUDY SELECTION

We included articles involving patient- and family-centered care interventions and quantitative, patient- and family-important outcomes in adult ICUs.

DATA EXTRACTION

We extracted the author, year of publication, study design, population, setting, primary domain investigated, intervention, and outcomes.

DATA SYNTHESIS

There were 46 studies (35 observational pre/post, 11 randomized) included in the analysis. Seventy-eight percent of studies (n = 36) reported one or more positive outcome measures, whereas 22% of studies (n = 10) reported no significant changes in outcome measures. Random-effects meta-analysis of the highest quality randomized studies showed no significant difference in mortality (n = 5 studies; odds ratio = 1.07; 95% CI, 0.95-1.21; p = 0.27; I = 0%), but there was a mean decrease in ICU length of stay by 1.21 days (n = 3 studies; 95% CI, -2.25 to -0.16; p = 0.02; I = 26%). Improvements in ICU costs, family satisfaction, patient experience, medical goal achievement, and patient and family mental health outcomes were also observed with intervention; however, reported outcomes were heterogeneous precluding formal meta-analysis.

CONCLUSIONS

Patient- and family-centered care-focused interventions resulted in decreased ICU length of stay but not mortality. A wide range of interventions were also associated with improvements in many patient- and family-important outcomes. Additional high-quality interventional studies are needed to further evaluate the effectiveness of patient- and family-centered care in the intensive care setting.

Non-pharmacological interventions to promote the sleep of patients after cardiac surgery: a systematic review

OBJECTIVE:

to analyze evidence available in the literature concerning non-pharmacological interventions that are effective to treat altered sleep patterns among patients who underwent cardiac surgery.

METHOD:

systematic review conducted in the National Library of Medicine-National Institutes of Health, Cochrane Central Register of Controlled Trials, Latin American and Caribbean Health Sciences Literature, Scopus, Embase, Cumulative Index to Nursing and Allied Health Literature and PsycINFO databases, and also grey literature.

RESULTS:

ten controlled, randomized clinical trials were included in this review. Non-pharmacological interventions were grouped into three main categories, namely: relaxation techniques, devices or equipment to minimize sleep interruptions and/or induce sleep, and educational strategies. Significant improvement was found in the scores assessing sleep quality among studies testing interventions such as earplugs, sleeping masks, muscle relaxation, posture and relaxation training, white noise, and educational strategies. In regard to the studies' methodological quality, high quality studies as established by Jadad scoring were not found.

CONCLUSION:

significant improvement was found among the scores assessing sleep in the studies testing interventions such as earplugs, sleeping masks, muscle relaxation, posture and relaxation training, white noise and music, and educational strategies.

The reliability of the German version of the Richards Campbell Sleep Questionnaire

BACKGROUND

The assessment of sleep quality in critically ill patients is a relevant factor of high-quality care. Despite the fact that sleep disturbances and insufficient sleep management contain an increased risk of severe morbidity for these patients, a translated and applicable instrument to evaluate sleep is not available for German-speaking intensive care settings.

AIM

This study aimed to translate the Richards Campbell Sleep Questionnaire (RCSQ), a simple and validated instrument eligible for measuring sleep quality in critically ill patients, and subsequently to evaluate the internal consistency of the German version of the RCSQ. Furthermore, it also aimed to inquire into the perception of sleep in a sample of critically ill patients.

METHODS

The RCSQ was translated following established methodological standards. Data were collected cross-sectionally in a sample of 51 patients at 3 intensive care units at a university hospital in Germany.

RESULTS

The German version of the RCSQ showed an overall internal consistency (Cronbach's alpha) of 0·88. The mean of the RSCQ in the sample was 47·00 (SD ± 27·57). Depth of sleep was rated the lowest and falling asleep again the highest of the RCSQ sleep items.

CONCLUSION

The study demonstrated very good internal consistency of the German version of the RCSQ, allowing for its application in practice and research in German-speaking countries. Quality of sleep perception was generally low in this sample, emphasizing the need for enhanced care concepts regarding the sleep management of critically ill patients. Relevance to clinical practice Assessment of self-perception of sleep is crucial in order to plan an individually tailored care process.

Knowledge and attitudes of primary care nurses about the management of patients with insomnia

OBJECTIVE

To describe the knowledge, attitudes, and performance of primary care nurses in the management of patients with insomnia.

METHODS

Descriptive study. An online questionnaire was sent to all primary care nurses of the Majorca Primary Care Department between June-July 2014.

MEASUREMENTS

sociodemographic variables, professional characteristics, tuition, usual clinical practice in the management of patients with insomnia.

RESULTS

138 nurses answered the questionnaire (47%). Most of them were women (92.8%), 50.42 years old (DE=8.9). The majority considered insomnia an important health problem. Only 11% had received some formative activity on insomnia in the last 5 years. Nearly half declares to ask patients about consequences of insomnia in their jobs and about habits that alter their sleep quality. 79.7% considered the possible adverse effects of insomnia drugs and take into consideration the age of patient (80.4%). The usual treatments were sleep hygiene (76%), phytotherapy (44.9%) and 22.4% cognitive behavioral therapy (CBT). This therapy is considered effective and applicable by nurses (63.7%) and doctors (58%). Those nurses who attended courses in the last 5 years apply CBT more frequently.

CONCLUSIONS

Nurses conduct a correct anamnesis and evaluation of patients with insomnia. However some therapies of known effectiveness, such as CBT, are still scarcely applied.

Exploring the Lived Experience of Difficult Sleep and Good Sleep Among Psychiatric Inpatients

The purpose of this qualitative study was to explore psychiatric inpatients' reflections on their experiences with sleep throughout their lives. Fourteen patients in an acute care behavioral health unit agreed to participate in this study. Participants met individually with a researcher to reflect on times in their lives when they experienced good sleep; times when they had difficulty sleeping; and times when difficult sleep was resolved. The major findings of the study indicated that feeling alone with life problems triggered difficult sleep; while feelings of belonging and purpose were associated with good sleep.

An integrative review of sleep for nutrition professionals

Sleep is an essential lifestyle factor that contributes to overall health. The inverse relation between sleep duration and weight status has revealed the importance of sleep in nutritional health. This integrative review builds foundational knowledge with regard to sleep vis-à-vis nutrition by summarizing the importance and process of sleep, current sleep recommendations and trends, as well as lifestyle contributors to poor sleep. Additionally, it details the association between sleep and obesity and potential mechanisms for this association. Furthermore, guidance is offered regarding the incorporation of sleep considerations in nutrition counseling, communication, and research. Like many other lifestyle factors that contribute to nutritional health, sleep needs to be considered when examining weight management and health promotion.

Relationship between nighttime vital sign assessments and acute care transfers in the rehabilitation inpatient

PURPOSE

To investigate the role of nighttime vital sign assessment in predicting acute care transfers (ACT) from inpatient rehabilitation.

DESIGN

Retrospective chart review.

METHODS

Fifty patients unexpectedly discharged to acute care underwent chart review to determine details of each ACT.

FINDINGS

Seven of 50 ACT possessed new vital sign abnormalities at the 11 pm vital sign assessment the night before ACT. None of these seven underwent ACT during the night shift the abnormalities were detected. Two of 50 ACT were transferred between 11 pm and 6:59 am; both demonstrating normal vital sign at the 11 pm assessment. During study period, an estimated 5,607 11 pm vital sign assessments were performed.

CONCLUSIONS

Nighttime vital sign assessments do not seem to be a good screening tool for clinical instability in the rehabilitation hospital.

CLINICAL RELEVANCE

Eliminating sleep disturbance is important to the rehabilitation inpatient as inadequate sleep hinders physical performance. Tailoring vital sign monitoring to fit patents' clinical presentation may benefit this population.

Effect of lavender aromatherapy on vital signs and perceived quality of sleep in the intermediate care unit: a pilot study

BACKGROUND

Sleep deprivation in hospitalized patients is common and can have serious detrimental effects on recovery from illness. Lavender aromatherapy has improved sleep in a variety of clinical settings, but the effect has not been tested in the intermediate care unit.

OBJECTIVES

To determine the effect of inhalation of 100% lavender oil on patients' vital signs and perceived quality of sleep in an intermediate care unit.

METHODS

A randomized controlled pilot study was conducted in 50 patients. Control patients received usual care. The treatment group had 3 mL of 100% pure lavender oil in a glass jar in place at the bedside from 10 pm until 6 am. Vital signs were recorded at intervals throughout the night. At 6 am all patients completed the Richard Campbell Sleep Questionnaire to assess quality of sleep.

RESULTS

Blood pressure was significantly lower between midnight and 4 am in the treatment group than in the control group (P = .03) According to the overall mean change score in blood pressure between the baseline and 6 am measurements, the treatment group had a decrease in blood pressure and the control group had an increase; however, the difference between the 2 groups was not significant (P = .12). Mean overall sleep score was higher in the intervention group (48.25) than in the control group (40.10), but the difference was not significant.

CONCLUSION

Lavender aromatherapy may be an effective way to improve sleep in an intermediate care unit.

Evaluating adult patients' sleep: an integrative literature review in critical care

BACKGROUND

Patients in a critical care unit sleep quite poorly even when they appear to be sleeping. Sleep is light and fragmented. Acute lack of sleep causes patients suffering in the form of fatigue, irritability, disorientation and hallucinations. It may also affect their recovery and immune defence. To promote sleep, nurses must be able to evaluate patients' sleep reliably.

AIM AND OBJECTIVES

Our aim was to form a comprehensive overview of the sleep evaluation methods in critical care. Our objectives were to determine the content and the quality of the methods as reported by the researchers. This overview hopefully improves the use of the sleep evaluation methods as part of sleep promoting nursing interventions and practices.

METHOD

The literature search was performed from the Ovid MEDLINE, CINAHL, an 'All EBM Reviews', and PsycINFO databases. The search terms sleep, evaluating sleep and critical care were used. An integrative review method was used to analyse the data.

RESULTS

According to the 52 articles of this review, there is a wide variety of methods to evaluate patients' sleep in critical care by observation, by asking for patient's own perception and by objective measures. Most instruments evaluate only total sleep time or the quality of sleep in general. The validity and reliability of the instruments has been insufficiently reported. Some questionnaires for patients' perception have been tested and used in several studies.

CONCLUSION

Sleep evaluation instruments do not cover all dimensions of sleep since they mostly measure total sleep time or estimate the overall quality of sleep. The quality of the sleep evaluation instruments varies from scientifically tested tools to untested instruments. This review will allow nurses to recognise the strengths and limitations of sleep evaluation instruments when selecting one to be used in critical care. Valid information about patients' sleep enables nurses to facilitate it.

Postoperative Respiratory Muscle Dysfunction

Postoperative pulmonary complications are responsible for significant increases in hospital cost as well as patient morbidity and mortality; respiratory muscle dysfunction represents a contributing factor. Upper airway dilator muscles functionally resist the upper airway collapsing forces created by the respiratory pump muscles. Standard perioperative medications (anesthetics, sedatives, opioids, and neuromuscular blocking agents), interventions (patient positioning, mechanical ventilation, and surgical trauma), and diseases (lung hyperinflation, obesity, and obstructive sleep apnea) have differential effects on the respiratory muscle subgroups. These effects on the upper airway dilators and respiratory pump muscles impair their coordination and function and can result in respiratory failure. Perioperative management strategies can help decrease the incidence of postoperative respiratory muscle dysfunction. Such strategies include minimally invasive procedures rather than open surgery, early and optimal mobilizing of respiratory muscles while on mechanical ventilation, judicious use of respiratory depressant anesthetics and neuromuscular blocking agents, and noninvasive ventilation when possible.

Promoting sleep for hospitalized patients with advanced cancer with relaxation therapy: experience of a randomized study

AIMS AND OBJECTIVES

Sleep disorders are frequent in patients with advanced cancer receiving palliative care. The objective of this study was to demonstrate whether relaxation therapy can improve their satisfaction with sleep.

BACKGROUND

Few studies have investigated the effectiveness of relaxation in patients hospitalized with an advanced chronic disease.

DESIGN

Prospective randomized study with an immediate intervention group (IIG; relaxation days 3-6) and a delayed intervention group (DIG; relaxation days 6-9).

METHODS

The main measure was the overall satisfaction of sleep measured on a Numerical Rating Scale of Satisfaction of Sleep (NRSSS) between 0 and 10.

RESULTS

Totally 18 (IIG: 9; DIG: 9) patients were included in this study (mean age 66 ± 10.7). The NRSSS improved in both the groups (almost statistically significant) between the day of inclusion and day 2. Because of the dropout of the patients during the last days of the study, we analyzed the improvement in sleep satisfaction only between day 2 and 5. The NRSSS D5 for the immediate and delayed groups were 4.0 ± 23 and 3.8 ± 2.3, respectively. There was no significant improvement in both the groups.

CONCLUSION

The results demonstrated the difficulty to include patients with advanced cancer in a randomized study with a DIG. We were not able to demonstrate the effectiveness of relaxation therapy on sleep satisfaction.

RELEVANCE TO CLINICAL PRACTICE

Techniques that can be easily used to improve sleep in patients with an advanced cancer should be developed and used already early in the disease.

A randomized controlled trial of the effects of listening to non-commercial music on quality of nocturnal sleep and relaxation indices in patients in medical intensive care unit

AIM

The purpose was to examine the effects of non-commercial music on quality of sleep and relaxation indices, including heart rate, mean arterial pressure, and respiratory rate in patients in intensive care units.

BACKGROUND

There is currently insufficient scientific knowledge for the effects of music on quality of sleep in critically ill patients.

DESIGN

A randomized controlled trial.

METHODS

Between January-December 2010, 28 patients aged 39-78 years were randomly assigned to music and control groups. Participants in the music groups listened to non-commercial music for 45 minutes at nocturnal sleep time. In the control group, participants slept with no music. Participants were assessed using vital signs monitors, standardized questionnaire, and polysomnography. Polysomnography sleep was recorded for the first 2 hours of the nocturnal sleep. General estimating equation was applied to analyse data.

FINDINGS

Participants in the music group had shorter stage N2 sleep and longer stage N3 sleep in the first 2 hours of the nocturnal sleep and improved self-reported sleep quality, compared with those in the control group. The music group patients also had significantly lower heart rates than those in the control group. The intensive care units patients experienced fragmented sleep with a high frequency of awakenings and severe reduction in random eye movement sleep during the first 2 hours of the nocturnal sleep.

CONCLUSION

The findings provided evidence for nurses to use soothing music as a research-based nursing intervention for intensive care unit patients' sleep improvement.
