Still too noisy - An audit of sleep quality in trauma and orthopaedic patients

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.

Evaluation of Sleep Quality and Its Relationship With Pain, Mood, and Physical Function After Orthopaedic Trauma Surgery: A Prospective Cohort Study

INTRODUCTION

Sleep disturbances are associated with pain and mental health. We prospectively compared a cohort of patients with orthopaedic trauma with a control group to establish the prevalence and duration of sleep disturbance and associations between sleep disturbance and pain, mood scores, and functional outcome scores.

METHODS

Subjects were patients with orthopaedic trauma undergoing in-patient surgical procedures and healthy control subjects from the community. Questionnaires completed by all subjects included the VAS numerical pain rating scale, the abbreviated profile of mood states, Patient-Reported Outcomes Measurement Information System Physical Function, and Patient-Reported Outcomes Measurement Information System Sleep Disturbance. Control subjects completed the surveys once, and subjects with trauma completed them at 2, 6, and 24 weeks postoperatively.

RESULTS

Healthy control subjects (28.6 ± 13.2) were significantly younger than patients with trauma (41.8 ± 18.9) ( P < 0.001). Compared with control subjects, at 2-week follow-up visit, patients with trauma had worse sleep ( P < 0.001) and worse mood ( P = 0.006). Across the study period, patients with trauma showed improvements in physical function ( P < 0.001) and pain (at rest [ P = 0.02], during activity [ P = 0.02], and at night [ P = 0.002]). In patients with trauma, better sleep disturbance scores were associated with better mood and less pain for all pain metrics ( P < 0.001).

DISCUSSION

Patients with orthopaedic trauma have worse sleep disturbance scores at 2 weeks postoperatively compared with normal control subjects; this difference attenuated at 6 weeks. Sleep disturbance was found to markedly correlate with pain and mood, with worse sleep quality associated with higher pain and worse mood. Improvement in sleep quality across 24 weeks postoperatively was associated with improvement in mood scores.

CONCLUSION

Patients should be counseled about the likely development of sleep disturbance and the possible association with worse emotional/mental health with worse sleep. Physicians should consider incorporating a multidisciplinary approach to the management of these select patients.

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.
