Sleep quality and sleep-disturbing factors of geriatric inpatients

Sleep trajectory of hospitalized medically ill older adults: do sleep medications make a difference?

STUDY OBJECTIVES

Sleep disturbances are prevalent during acute hospitalization in medically ill older patients, with undesirable outcomes. Sleep medication use is common, but its effectiveness is questionable. This study explored the trajectory of sleep parameters from home to hospital and assessed the impact of sleep medication use, considering covariates such as physical symptom burden.

METHODS

A prospective multicenter study was conducted in four Israeli hospitals. Cognitively intact older patients (n = 683), with an admission interview and at least one follow-up, were recruited. Total sleep time (TST), sleep efficiency (SE), sleep quality (SQ), number of awakenings (NOAs), sleep medication use, sleep medication burden (quantity and dosage), and physical symptom burden were recorded daily. Personal and illness-related covariates were included in a repeated measures mixed models design.

RESULTS

Participants (male: 54%, aged 77.31 ± 6.60) showed shorter TST (329.73 ± 111.94 vs. 377.03 ± 101.06 min), lower SE (71.49 ± 19.28% vs. 76.14 ± 15.53%), and higher probability for lower SQ, in the hospital compared to home. Sleep medication use was not correlated with any sleep parameters; sleep medication burden was associated with NOA. Physical symptom burden showed significant main effects on SE, SQ, and NOA, and a significant interaction was found with time points on TST, such that higher burden was more strongly associated with shorter TST at first in-hospital follow-up than at admission, with no differences between all subsequent in-hospital time points.

CONCLUSIONS

Sleep declined during acute hospitalization compared to the home, with sleep medications showing minimal effect. Managing symptom burden should be prioritized when addressing sleep disturbances in older patients during hospitalization.

Restless legs syndrome and ferritin levels in older adults with dementia: a cross-sectional study

In cases of dementia or major neurocognitive disorder, restless legs syndrome has not been extensively studied because the diagnosis relies on clinical assessments and self-reports from patients.

Objective

The aim of this study was to investigate the association between Willis-Ekbom disease/restless legs syndrome and iron-deficiency anemia in older adults with dementia.

Methods

A cross-sectional study was conducted with 70 older adults diagnosed with dementia and restless legs syndrome at a psychogeriatric clinic in the state of São Paulo, Brazil. The participants answered data collection instruments addressing sociodemographic characteristics, restless legs syndrome, neuropsychiatric symptoms, sleep quality, daytime sleepiness, and cognitive function. Creatinine, ferritin, red blood cells, hemoglobin, and hematocrit were determined by blood exams (the latter of which was collected from the patient records).

Results

The sample was composed predominantly of individuals with mixed dementia (i.e., Alzheimer's disease+vascular dementia). Women accounted for 55.7% of the sample, with a mean age of 77.80±9.36 years. The prevalence of restless legs syndrome among the participants was found to be 15.7%. Individuals with this syndrome had greater frequencies of neuropsychiatric symptoms, poor sleep quality, higher BMI, and lower ferritin levels (p<0.05).

Conclusion

The prevalence of restless legs syndrome among older adults with dementia was 15.7%, and individuals with this syndrome had ferritin deficiency.

Sleep hygiene education in older adults: effectiveness and association with comprehensive geriatric assessment

OBJECTIVES

This study aimed to evaluate the results of sleep hygiene education via a comprehensive geriatric assessment.

METHOD

A cross-sectional research was conducted on insomnia outpatients at a tertiary hospital, and all participants received sleep hygiene education as well as a comprehensive geriatric assessment. Sleep parameters were assessed before and four weeks after education.

RESULTS

The study included 141 participants. A significant improvement was obtained in all four scales' scores before and after education (PSQI score 11 [8-13] vs. 5 [3-9], p < .001; SHI score 12 [8-16] vs. 4 [1-8], p < .001; ESS score 6 [3-8] vs. 2 [0-6], p < .001; Jenkins SS score 15 [10-19] vs. 7 [5-11], p < .001). Female gender ratios, as well as the presence and risk of malnutrition, differed between groups with and without the PSQI score improvement. In the regression analyses, female gender and the presence of malnutrition or malnutrition risk were evaluated as possible factors affecting the PSQI responses (respectively, OR: 3.48, CI 95%: 1.21-10.00, p = .020; OR: 0.29, CI 95%: 0.09-0.949, p = .041).

CONCLUSION

Sleep hygiene education and interdisciplinary interventions are crucial in the management of sleep disorders in older adults.

Clinical characteristics of older patients with suspected or diagnosed dementia during hospitalization

AIM

In Japan, an additional system for patients with suspected or diagnosed dementia during hospitalization for physical illness began in 2016. We examined the clinical characteristics of older patients with suspected or diagnosed dementia during hospitalization.

METHODS

The study participants consisted of 569 patients. Current age, sex, comorbidities, causative disease for admission, body mass index (BMI), blood tests, environment before admission, prescription history before admission and rate of delirium were examined. Simple regression analysis for high-frequency diseases was carried out with the respective risk factors as independent variables. Multiple regression analysis was then carried out.

RESULTS

Infection had the highest frequency in the causative diseases for admission. A total of 48% of patients had delirium during hospitalization. The delirium group had the highest frequency of being at home. In the infection group, BMI and serum albumin were lower in the non-infection group (BMI 19.0 ± 3.7 vs 20.4 ± 4.1; P < 0.001, albumin 2.1 ± 0.7 vs 3.3 ± 0.6 g/dL; P < 0.001 respectively). White blood cell count and C-reactive protein were higher than in the non-infection group, respectively (white blood cell count 11181.4 ± 6533.3 vs 8765.8 ± 111 424.3/μL; P = 0.007, C-reactive protein 8.6 ± 8.6 vs 3.0 ± 5.2 mg/dL; P < 0.001 respectively). Using independent factors associated with infection, multiple regression analysis was performed. BMI (P = 0.013), serum albumin (P < 0.001) and nursing home care before admission (P < 0.001) had significant correlations.

CONCLUSIONS

Assessment of delirium and the environment before admission of older patients with suspected or diagnosed dementia when hospitalized are necessary. Furthermore, evaluation of nutrition might also contribute to reducing deterioration due to physical illness. Geriatr Gerontol Int 2024; 24: 641-645.

Orthopaedic patients' experiences of their sleep during hospitalisation and suggestions for improvements

PURPOSE

To describe orthopaedic patients' perspectives on their sleep quality and their suggestions for improvement initiatives to achieve better sleep quality during hospitalisation.

METHODS

In a qualitative design, 265 (50%) of 533 patients from a questionnaire survey responded to two free-text questions. Data were analysed based on a phenomenological-hermeneutic approach inspired by Paul Ricoeur's theory of narrative and interpretation.

RESULTS

Three themes emerged: 1) Sleeping environment and preferences tailored to the individual patient, 2) The link between orthopaedic surgery care and sleeping, and 3) Noise challenged a good night's sleep. Good sleep was related to nurses' professional behaviour and the physical environment, such as quality beds and sleeping aids. Single and shared rooms, room lighting, and fresh air all influenced sleep quality. Unfamiliar and uncomfortable sleeping positions posed a challenge for orthopaedic patients but aids such as pillows, and duvets could provide more comfort at night. Offset circadian rhythms could affect sleep quality, as could nausea and vomiting. Pain and lack of pain relief were associated with poor sleep quality. Noise from both nurses and other patients affected sleep quality. Therefore, unnecessary care activities should be kept to a minimum, and a "night noise level" was suggested.

CONCLUSION

Patients' sleep disturbance following orthopaedic surgery needs to be addressed by both nurses and hospital management. Patients' involvement is essential to create a sleep environment tailored to individual needs and to provide strategies patients use at home for addressing sleeping problems.

The relationship between sleep status and activity of daily living: based on China Hainan centenarians cohort study

OBJECTIVE

This study, based on the China Hainan Centenarians Cohort Study (CHCCS), aims to comprehensively describe the characteristic of daytime, night and total sleep duration, sleep quality and different sleep mode of Hainan centenarians and their associations with activity of daily living (ADL) functions.

METHOD

The baseline data of CHCCS was used. ADL function was evaluated the Bathel index, sleep quality was evaluated by Pittsburgh sleep quality index (PSQI), sleep status including daytime, night and total sleep duration as well as sleep quality and sleep mode. Multivariate logistic regression model was used to explore the association between sleep status and ADL disability and ADL moderate & severe disability.

RESULTS

A total of 994 centenarians were included in this study with the age range 100-116 years old. Compared with the centenarians who sleep 6-9 h at night and < 2 h in the daytime, the adjusted OR between sleep > 9 h at night and sleep ≥ 2 h in the daytime and ADL disability was 2.93 (95% CI: 1.02-8.44), and adjusted OR of ADL moderate & severe disability was 2.75 (95% CI: 1.56-4.83). Compared with centenarians who sleep for 7-9 h and have good sleep quality, centenarians who sleep for > 9 h and have poor sleep quality have an increased risk of ADL moderate & severe disability (OR = 3.72, 95% CI: 1.54-9.00).

CONCLUSION

Relation between sleep duration and ADL disability was more significant compared with sleep quality in Hainan centenarians. Poor sleep quality can aggravate the relationship between sleep duration and ADL moderate & severe disability.

The sleep patterns and their associations with mental health among nursing home residents: a latent profile approach

BACKGROUND

Nursing home residents commonly experience poor sleep conditions. However, few studies have explored the potential sleep patterns among nursing home residents. This study aimed to identify the sleep patterns in nursing home residents, compare residents' characteristics across sleep patterns, and examine the relationships between sleep patterns and residents' mental health (i.e., depressive and anxiety symptoms).

METHODS

This cross-sectional study was conducted in 27 nursing homes in Jinan, China, from March to June 2018. In total, 353 participants were recruited via convenience sampling, and of which, 326 completed the survey. A latent profile analysis was performed to identify sleep patterns based on the seven dimensions of the Pittsburgh Sleep Quality Index. Bivariate analyses were conducted to compare residents' characteristics among the sleep patterns. Mixed-effects logistic regression analyses were adopted to investigate the relationships between sleep patterns and residents' mental health.

RESULTS

Three sleep patterns were identified, including 'good sleepers', 'poor sleepers without hypnotic use', and 'poor sleepers with hypnotic use'. Residents' gender, education, pain, instrumental activities of daily living, and number of chronic conditions were significantly differentiated across the sleep patterns. Compared with 'good sleepers', 'poor sleepers without hypnotic use' were significantly associated with more depressive symptoms (OR = 3.73, 95% CI = 2.09, 6.65, p < 0.001), but not with anxiety symptoms (OR = 2.04, 95% CI = 0.97, 4.29, p = 0.062); whereas 'poor sleepers with hypnotic use' had significantly more depressive (OR = 5.24, 95% CI = 2.54, 10.79, p < 0.001) and anxiety symptoms (OR = 5.02, 95% CI = 2.13, 11.83, p < 0.001).

CONCLUSIONS

This study reveals three distinct sleep patterns in nursing home residents and their significant associations with residents' mental health. These findings can inform future research to develop appropriate and tailored intervention strategies for improving sleep and promoting mental health for nursing home residents.

Sleep quality among inpatients of Spanish public hospitals

Sleep is a complex process and is needed both in health and illness. Deprivation of sleep is known to have multiple negative physiological effects on people's bodies and minds. Despite the awareness of these harmful effects, previous studies have shown that sleep is poor among hospitalised patients. We utilized an observational design with 343 patients recruited from medical and surgical units in 12 hospitals located in nine Spanish regions. Sociodemographic and clinical characteristics of patients were collected. Sleep quality at admission and during hospitalisation was measured by the Pittsburgh Sleep Quality Index. Sleep quantity was self-reported by patients in hours and minutes. Mean PSQI score before and during hospitalisation were respectively 8.62 ± 4.49 and 11.31 ± 4.04. Also, inpatients slept about an hour less during their hospital stay. Lower educational level, sedative medication intake, and multi-morbidity was shown to be associated with poorer sleep quality during hospitalisation. A higher level of habitual physical activity has shown to correlate positively with sleep quality in hospital. Our study showed poor sleep quality and quantity of inpatients and a drastic deterioration of sleep in hospital versus at home. These results may be helpful in drawing attention to patients' sleep in hospitals and encouraging interventions to improve sleep.

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.

Neuropathic Pain in Hand Osteoarthritis: A Cross-Sectional Study

Symptomatic hand osteoarthritis (OA) is a severely debilitating condition. Neuropathic pain (NP) has been shown to be a factor affecting pain severity, hand function, psychological wellbeing, body schema, and the number of pain medications in people with OA of other joints. The aim of this study was to assess the prevalence of NP in symptomatic hand OA and assess its association with pain, hand function, measures of psychological wellbeing, sleep, body schema disturbances, and number of pain medications. Participants with symptomatic hand OA diagnosed through the American College of Rheumatology criteria, were recruited and completed a series of online questionnaires. These included the Douleur Neuropathique 4 interview (DN4-interview), Short Form Brief Pain Inventory (SF-BPI), Neglect-like Symptoms questionnaire, Functional Index of Hand Osteoarthritis (FIHOA), Centre for Epidemiologic Studies Depression Scale (CES-D), Pain Catastrophising Scale (PCS), and the Pittsburgh Sleep Quality Index (PSQI). Logistic regression with age, body mass index, and sex as covariates were utilised to assess differences between participants with and without NP as identified through the DN4-interview. Correlation analysis assessed the relationship between pain intensity, body schema alterations, and number of pain medications. A total of 121 participants were included in the present study. Forty-two percent of participants presented with NP. Participants with NP reported higher levels of worst pain (OR: 10.2 95% CI: 2.2 to 48.5; p = 0.007). Worst pain intensity correlated with the number of pain medications (rho = 0.2; p = 0.04), and neglect-like symptoms (rho = 0.4; p < 0.0001). No difference between phenotypes was shown for catastrophising, function, depression, neglect-like symptoms, pain interference, or sleep. A large proportion of people with symptomatic hand OA present with NP. This phenotype is characterised by greater levels of pain intensity. Pain intensity is associated with number of pain relief medications and body schema alteration. Psychological factors, hand function, and sleep do not appear to be affected by the presence of NP.

Insomnia and falls in older adults: are they linked to executive dysfunction?

BACKGROUND

Insomnia increases the incidence of falls and impairs executive function. Moreover, falls are associated with executive function impairment. The relationship between falls and executive function in patients with insomnia is not clear. The aim of this study was to evaluate relationship between falls and executive function in individuals with insomnia and a control group.

METHODS

This study involved 122 patients (47 insomnia, 75 controls). The Mini-Mental State Examination, Quick Mild Cognitive Impairment Screen, Trail Making Test A, clock-drawing test, and digit span test were used to measure executive function. Semantic and working memory dual task was also performed. Fall history was recorded and the Falls Efficacy Scale - International administered.

RESULTS

The median age of the patients was 71 years (range: 65-89 years), and 60.7% were women. The insomnia group scored lower on the three-word recall than the control group (P = 0.005), but there was no difference between the groups on cognitive tests. Fall history and fear of falling were more frequent in the insomnia group (P = 0.003, P < 0.001). Semantic and working memory dual tasks were correlated with clock-drawing test only in the insomnia group (r = -0.316, P = 0.031; r = -0.319, P = 0.029). Depression (odds ratio (OR) = 9.65, P = 0.001) and Trail Making Test A (OR = 1.025, P = 0.07) were independently associated with insomnia. Four-metre walking speed (OR = 2.342, P = 0.025), insomnia (OR = 3.453; P = 0.028), and the semantic memory dual task (OR = 1.589; P = 0.025) were also independently associated with falls.

CONCLUSION

Our study showed that dual tasking and executive function are related to falls in patients with insomnia. Managing insomnia and assessment of executive dysfunction may have beneficial effects on preventing falls.
