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

Sleep-enhancing nursing interventions in hospital wards: A systematic review

AIM

To identify sleep-promoting nursing interventions in hospitalized adults and older people.

BACKGROUND

Sleep is necessary for maintaining good physical and mental health, as well as a high quality of life. Hospitalization can significantly disrupt sleep patterns, which is an often-overlooked issue. Nurses are the main participants in promoting sleep in hospitalized patients.

METHODS

Systematic literature review based on the question: "What interventions can nurses implement to promote sleep in hospitalized adults and older people?". The research was conducted on April 4, 2023, in CINAHL Complete, MEDLINE, Cochrane, Scopus, and Web of Science, filtering the articles published in the last 10 years. For a study to be included, it must feature adult or older participants, an intervention that aims to enhance sleep, and the research should have been conducted within a hospital setting. We followed the PRISMA flow diagram and analyzed the quality of the articles according to the Joanna Briggs Institute criteria for quality assessment. The results were subjected to a narrative synthesis.

RESULTS OR FINDINGS

Of the 712 articles found, 13 were selected. The sample encompasses 1975 participants. These selected articles emphasize educational and communicative interventions, dietary and sensory interventions, symptomatic and environmental control, daily activity planning, sleep assessment and documentation, and individualized nursing care.

DISCUSSION

There is a need for a systematic approach incorporating physical, psychosocial, and relational dimensions within the care context.

CONCLUSION

It is necessary to raise the nurses' awareness of the factors that affect sleep experience and empower them to promote sleep in partnership with hospitalized patients.

IMPLICATIONS FOR NURSING AND HEALTH POLICY

Sleep interventions can be promoted by implementing hospital policies, including environmental modifications in the design and refurbishment of facilities and restricting nighttime patient transfers to reduce noise and disturbances. Encouraging research studies that explore the effectiveness of these interventions will further support the development of evidence-based policies aimed at improving sleep quality in hospitalized patients.

Improving sleep quality in maternity patients in a Singapore academic hospital: a best practice implementation project

INTRODUCTION

Prolonged sleep deprivation and poor sleep quality are common complaints among pregnant and postpartum women, and they have adverse effects on the physiological and psychological well-being of mothers antenatally and postnatally.

OBJECTIVES

The aim of this project was to improve antenatal and postnatal mothers' night-time sleep quality during hospitalization in an obstetric ward through multi-faceted interventions.

METHODS

This project followed the JBI Model of Evidence-based Healthcare and applied the seven phases of the JBI Evidence Implementation Framework to conduct context analysis, strategy implementation, and review of practice using evidence-based audit criteria. JBI's Practical Application of Clinical Evidence System and the Getting Research into Practice situational analysis tool were used to support data collection and identify barriers and strategies. Mothers' sleep quality was measured using an adapted St. Mary's Hospital Sleep Questionnaire.

RESULTS

Baseline audit results (0%) revealed that midwives and nurses were not implementing the multi-faceted interventions to promote sleep in mothers. The results in follow-up audit 1 and follow-up audit 2 achieved compliance of 63.3% ( p < 0.000), respectively. Overall, the mothers were fairly satisfied with their sleep quality, were able to sleep longer, and felt more alert when waking up in the morning.

CONCLUSIONS

There was an increase in compliance with best practices to improve mothers' sleep quality in the obstetric wards, although these results could be further improved. Mothers' perspectives of sleep promotion strategies should be explored in future projects to tailor the strategies to their needs. Sustainability plans include conducting follow-up audits and engaging ward nurses to continue implementing the multi-faceted interventions.

Redesigning the Hospital Environment to Improve Restfulness

Importance

Hospital wards are often not conducive to patient sleep, negatively affecting patient health and experience.

Objectives

To assess determinants of in-hospital restfulness and to design and test rest-promoting interventions on the wards in partnership with clinicians, staff, and patients.

Design, Setting, and Participants

This rapid-sequential mixed-methods quality improvement study was performed at a large urban academic hospital in St Louis, Missouri, from May 1, 2021, to December 31, 2022, with follow-up through hospitalization. Mixed-methods activities involved purposively selected hospitalized adults on the wards, nurses, hospitalists, and hospital staff. Interventions included all adult hospitalizations on the study wards.

Interventions

Sequential stacked bundles of multimodal rest-promoting interventions (general education, focused education on light or noise, safely reducing overnight monitoring or testing, and environmental personalization).

Main Outcomes and Measurements

Pre-post comparisons of perceived nighttime quietness (via surveys) and sleep opportunity (coprimary outcomes) as well as clinical interruptions overnight, environmental noise, and adoption and satisfaction.

Results

Nine patients (4 female) and 14 staff members (10 female; 3 nurse managers or administrators, 10 nurses, and 1 physician) were interviewed, 38 surveys were collected, and more than 100 hours of observation were performed. Interventions were evaluated for 671 patients (mean [SD] age, 60 [16] years; 336 [50%] female). Determinants of in-hospital rest included infrastructure, staff attitudes, priorities, culture, and patient experiences of anxiety, uncertainty, and loss of control. Informed by these determinants, codesign workshops yielded 39 potential interventions, from which 9 were selected for testing. Related interventions were organized into bundles, which were tested in sequential 2-week sprints. Perceived nighttime quietness improved nonsignificantly during the project (wards "always" quiet at night: 51% preintervention vs 86% postintervention; P = .09), with excessive noise events decreasing from 0.65 (95% CI, 0.53-0.77) to 0 per 100 patient-nights before the intervention (P = .02). Sleep opportunity improved significantly (mean, 4.94 [95% CI, 4.82-5.06] hours per patient-night before the intervention vs 5.10 [95% CI, 5.00-5.20] hours per patient-night after the intervention; P = .01).

Conclusions and Relevance

In this quality improvement study, a set of feasible, acceptable, and beneficial rest-promoting interventions were developed. After implementation of these interventions on the wards, a significant improvement in nighttime quietness and sleep opportunity was observed. These results demonstrate how human-centered design methods can generate practical and effective strategies for improving an important patient-related outcome and a core element of patient experience.

Sleep quality after autologous breast reconstruction

BACKGROUND

Sleep is a fundamental aspect of human health and well-being, but is often interrupted in a hospital setting. Especially after surgery, poor sleep quality can negatively affect postoperative recovery and quality of life. Therefore, the aim of this study was to gain insights into the quality of sleep in patients after autologous breast reconstruction and evaluate factors associated with the quality of sleep.

MATERIALS AND METHODS

In this single-center observational cohort study, participants completed a sleep diary, including the Pittsburgh sleep quality index (PSQI) and EQ-5D-5L quality of life questionnaire, before surgery, during hospital admission, and two weeks and three months postoperative. Additional variables such as pain and anesthesia duration were collected.

RESULTS

Twenty-nine patients were included. Before the surgery, 58% of them experienced poor quality of sleep, with a median PSQI score of 5.0. During hospital admission, 83% of the patients had poor quality of sleep, with a PSQI score of 6.0. The PSQI score two weeks postoperative increased to 7.0 and decreased three months postoperative to 5.0. Patients with pain scores >4 ("pain" group), had higher median PSQI scores than patients with pain scores ≤4 ("no pain" group) at all postoperative time points previously mentioned. No correlation was observed between anesthesia duration or quality of life.

CONCLUSION

Poor sleep quality was experienced by most women after autologous breast reconstruction, especially in those with higher postoperative pain scores. This knowledge offers an opportunity to improve the postoperative care for such patients.

Effectiveness of sound and darkness interventions for critically ill patients' sleep quality: A systematic review and component network meta-analysis

BACKGROUND

Noise and lighting are prime factors of poor sleep quality in critically ill patients, which impair recovery and increase the risk of delirium or complications.

AIM

To identify and rank the effectiveness of sound and darkness interventions on the sleep quality of critically ill patients.

STUDY DESIGN

This systematic review and component network meta-analysis was based on the Preferred Reporting Items for Systematic Reviews incorporating the Network Meta-Analyses (PRISMA-NMA) Statement. The Embase, MEDLINE, Cochrane CENTRAL, CINAHL, Airiti Library, and Google Scholar databases were searched from inception to August 10, 2021, for randomized controlled trials (RCTs) on sound and darkness interventions targeting critically ill patients' sleep quality. We applied standard and component NMA to determine the effects of interventions. The certainty of evidence was evaluated using the Cochrane risk-of-bias tool (V.2.0) and the online Confidence in Network Meta-Analysis (CINeMA) application.

RESULTS

Twenty-four RCTs with 1507 participants who used combined interventions constituting seven competing interventions were included in the standard NMA. The combination of earplugs, eye masks, and music; eye masks alone; earplugs combined with eye masks; and music alone had beneficial intervention effects. The combination of earplugs, eye masks, and music was the best intervention, and these components had no interaction effect. An eye mask had the best relative effect, followed by music, quiet time, and earplugs.

CONCLUSIONS

This study provides clinical evidence of the effectiveness of using eye masks, music, and earplugs to improve sleep quality in critically ill patients. We also recommend future research using bedtime music, nocturnal eye masks, and quiet time, which had the best relative effects on sleep quality.

RELEVANCE TO CLINICAL PRACTICE

This study provides recommendations for interventions that nurses can use to improve critically ill patients' sleep quality.

Hospitalized Patients' Sleep Quality Compared Between Multioccupancy Rooms and Single-Patient Rooms

OBJECTIVES

To evaluate patients' sleep quality in a former hospital with two-and four-bedded rooms compared to a new hospital that incorporated evidence-based design features, including exclusively single-patient rooms (SPRs).

BACKGROUND

Hospitalized patients often report poor sleep quality due to both patient-related factors and hospital environmental factors. It is unclear if staying in an SPR in a hospital designed as a healing environment is associated with better sleep quality.

METHODS

In a before-after study, sleep quality, duration, and efficiency over 72 hr were measured with a sleep diary, GENEActiv accelerometer, and the Richards-Campbell Sleep Questionnaire (RCSQ) with scores ranging from 0 to 100, with higher scores reflecting better sleep. Participants were either staying alone in the former hospital with two-and four-bedded rooms (Group 1), sharing a room with one to three fellow patients (Group 2), or staying alone in a newly designed hospital with 100% SPRs (Group 3).

RESULTS

We included 17 patients in Group 1, 32 patients in Group 2, and 56 patients in Group 3. Univariable linear mixed model analysis, controlling for night number, revealed that the RCSQ total score was lowest in Group 2 compared to the other two groups. In the multivariable analysis, the RCSQ score was also the lowest in Group 2, with a significant effect from covariate "use of night medication."

CONCLUSION

Self-reported sleep quality of hospitalized patients in a hospital with 100% SPRs designed as a healing environment was slightly better than that of patients staying in multioccupancy rooms with fellow patients.

Society of Anesthesia and Sleep Medicine Position Paper on Patient Sleep During Hospitalization

This article addresses the issue of patient sleep during hospitalization, which the Society of Anesthesia and Sleep Medicine believes merits wider consideration by health authorities than it has received to date. Adequate sleep is fundamental to health and well-being, and insufficiencies in its duration, quality, or timing have adverse effects that are acutely evident. These include cardiovascular dysfunction, impaired ventilatory function, cognitive impairment, increased pain perception, psychomotor disturbance (including increased fall risk), psychological disturbance (including anxiety and depression), metabolic dysfunction (including increased insulin resistance and catabolic propensity), and immune dysfunction and proinflammatory effects (increasing infection risk and pain generation). All these changes negatively impact health status and are counterproductive to recovery from illness and operation. Hospitalization challenges sleep in a variety of ways. These challenges include environmental factors such as noise, bright light, and overnight awakenings for observations, interventions, and transfers; physiological factors such as pain, dyspnea, bowel or urinary dysfunction, or discomfort from therapeutic devices; psychological factors such as stress and anxiety; care-related factors including medications or medication withdrawal; and preexisting sleep disorders that may not be recognized or adequately managed. Many of these challenges appear readily addressable. The key to doing so is to give sleep greater priority, with attention directed at ensuring that patients' sleep needs are recognized and met, both within the hospital and beyond. Requirements include staff education, creation of protocols to enhance the prospect of sleep needs being addressed, and improvement in hospital design to mitigate environmental disturbances. Hospitals and health care providers have a duty to provide, to the greatest extent possible, appropriate preconditions for healing. Accumulating evidence suggests that these preconditions include adequate patient sleep duration and quality. The Society of Anesthesia and Sleep Medicine calls for systematic changes in the approach of hospital leadership and staff to this issue. Measures required include incorporation of optimization of patient sleep into the objectives of perioperative and general patient care guidelines. These steps should be complemented by further research into the impact of hospitalization on sleep, the effects of poor sleep on health outcomes after hospitalization, and assessment of interventions to improve it.

Piloting I-SLEEP: a patient-centered education and empowerment intervention to improve patients' in-hospital sleep

Background

Sleep disturbances in hospitalized patients are linked to poor recovery. In preparation for a future randomized controlled trial, this pilot study evaluated the feasibility and acceptability of a multi-component intervention (I-SLEEP) that educates and empowers inpatients to advocate for fewer nighttime disruptions in order to improve sleep during periods of hospitalization.

Methods

Eligible inpatients received I-SLEEP, which included an educational video, brochure, sleep kit, and three questions patients can ask their team to reduce nighttime disruptions. Following I-SLEEP, inpatients were surveyed on the primary feasibility outcomes of satisfaction with and use of I-SLEEP components. Inpatients were also surveyed regarding empowerment and understanding of intervention materials. Patient charts were reviewed to collect data on nighttime (11 PM–7 AM) vital sign and blood draws disruptions.

Results

Ninety percent (n = 26/29) of patients were satisfied with the brochure and 87% (n = 27/31) with the video. Nearly all (95%, n = 36/37) patients felt empowered to ask their providers to minimize nighttime disruptions and 68% (n = 26/37) intended to alter sleep habits post-discharge. Forty-nine percent (n = 18/37) of patients asked an I-SLEEP question. Patients who asked an I-SLEEP question were significantly more likely to experience nights with fewer disruptions due to nighttime vitals (19% vs. 2.1%, p = 0.008).

Conclusion

This pilot study found that I-SLEEP was well-accepted and enabled hospitalized patients to advocate for less disrupted sleep. Educating patients to advocate for reducing nighttime disruptions may be a patient-centered, low-cost strategy to improve patients’ care and in-hospital experience. These results suggest that I-SLEEP is ready to be evaluated against routine care in a future randomized controlled trial.
