ObjectiveSleep disruption occurs frequently in hospitalised patients. Given the potential of music intervention as a non-pharmacological measure to improve sleep quality, we aimed to assess and quantify current literature on the effect of recorded music interventions on sleep quality and quantity in the adult critical care and surgical populations.DesignSystematic review and meta-analysis.Data sourcesEmbase, MEDLINE Ovid, Cochrane Central, Web of Science and Google Scholar.Eligibility criteria for studiesRandomised controlled trials assessing the effect of music on sleep quality in critically ill and surgical patients.MethodsThe electronic databases were systematically searched from 1 January 1981 to 27 January 2020. Data were screened, extracted and appraised by two independent reviewers. Primary outcomes were sleep quality and quantity, assessed with validated tools. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed.

“…Wang et al investigated morbidity and symptom prevalence in the elderly and found that elderly individuals mostly experience sleep problems (37.7%) 6 . Many studies have reported that individuals aged 65 and over frequently experience sleep problems 6‐11 .

With the decline in birth rate and improving living standards all over the world, life expectancy, and thus the elderly population, is gradually increasing. 1,2 As of 2019, the population aged 60 and over in the world is 962 million, and this figure is expected to increase rapidly and reach 1.4 billion in 2030 and 2.1 billion in 2050. 3 Because of the global ageing of the world population and the increase in the elderly population, age-related physiological changes, and related problems arise. With ageing, chronic diseases (Hypertension, Chronic Obstructive Pulmonary Disease, Dementia) problems such as fatigue, imbalance, osteoporosis, urinary retention, and disorientation become more common in elderly individuals.In addition, one of the most common problems seen independent of diseases is sleep disorders. 4,5 Wang et al investigated morbidity and symptom prevalence in the elderly and found that elderly individuals mostly experience sleep problems (37.7%). 6 Many studies have reported that individuals aged 65 and over frequently experience sleep problems. [6][7][8][9][10][11] It has been determined that elderly individuals generally experience problems such as falling asleep, waking up frequently at night, sleeping too much during the day, insomnia, and waking up early. 12,13 It has been reported that 20%-50% of adult individuals and 57% of home-dwelling elderly people in Western countries suffer from sleep problems and this rate is higher in elderly people living in nursing homes. [10][11][12][13][14][15] The prevalence of urinary incontinence increases with ageing and it is another important geriatric condition that causes problems during sleep by increasing the frequency of urination at night. The fact that urinary incontinence is a social problem that is generally not mentioned by the elderly leads to under-diagnosis and urinary
“…We assessed the degree of patient' subjectively experienced sleep problems and did not examine objective criteria of sleep quality or diagnoses of insomnia based on semi-structured interviews. Subjective and objective measurement methods can differ substantially [48,49]. The sample of cancer patients who were all receiving treatment in a rehabilitation clinic is not totally representative of cancer patients in general.…”
Objective
The objectives of this study were to examine sleep problems in cancer patients, to test the psychometric properties of the Insomnia Sleep Index (ISI) in comparison with the sleep item of the Patient Health Questionnaire-9 (PHQ-9), and to analyze disrupting factors which might cause the sleep problems.
Methods
A sample of 1026 mixed-site cancer patients in treatment at a German oncological rehabilitation clinic was examined.
Results
The reliability of the ISI was very good (Cronbach’s alpha = 0.92), and the results of the confirmatory factor analysis were acceptable. Females reported worse sleep quality (ISI mean: 13.7 ± 6.6) than males (10.7 ± 6.4). Sleep problems as measured with the PHQ-9 sleep item were markedly higher than those in the general population (effect size d = 1.15).
Patients reported that, of the factors that disrupted their sleep, psychological factors (brooding, worries) were more relevant than symptom factors (pain, nocturnal urination, or restless legs).
Conclusions
The ISI is effective in detecting sleep problems in cancer patients. Normative studies with the ISI would be helpful for assessing ISI mean scores. Sex differences should be taken into account when groups of patients are compared. The sleep item of the PHQ-9 can be used in epidemiological studies.
