The effects of music-based interventions on behavioural and psychological symptoms of people living with dementia: a systematic review and network meta-analysis protocol.

OBJECTIVES: People living with dementia often experience behavioural and psychological symptoms of dementia (BPSD), which severely affect their well-being during the course of the disease. Particularly for BPSD outcomes, there is a high demand for increasing the evidence-based knowledge of non-pharmacological approaches, such as music-based interventions. Although previous reviews emphasize the potential effects of music-based interventions in people with dementia, they cover a wide range of different interventions and outcomes. METHOD: Therefore, this systematic review (SR) and network meta-analysis (NMA) aims to not only investigate the efficacy of music-based interventions on BPSD, but also to compare the impact of different types of music-based interventions on outcomes. Preferred reporting items for SR and meta-analysis protocols (PRISMA-P) and the PRISMA NMA extension were followed. Several databases will be searched from inception to the date the search will be performed, for relevant randomized or non-randomized controlled trials comparing a music-based intervention with treatment as usual, active controls, or another music-based intervention. Multivariate pairwise meta-analyses will be conducted for each outcome. NMA based on a frequentist random-effects model will be used to estimate the comparative effects of each type of music-based intervention and related components across outcomes. Heterogeneity will be investigated by meta-regression models. CONCLUSION: Based on our knowledge, this may be the first SR and NMA study to compare the efficacy of different types of music-based interventions. In addition, combined with our multivariate analysis approach, it will allow us to identify potential effect modifiers in music-based intervention for treating BPSD.

Systematic review on music interventions during pregnancy in favor of the well-being of mothers and eventually their offspring.

OBJECTIVE: Mental health affects maternal well-being and indirectly affects the development of fetal brain structures and motor and cognitive skills of the offspring up to adulthood. This study aimed to identify specific characteristics of music interventions that improve validated maternal outcomes. DATA SOURCES: Randomized controlled trials and systematic reviews investigating music interventions during pregnancy were identified from the start of data sources up to December 2023 using MEDLINE, the Cochrane Central Register of Controlled Trials, or Web of Science. STUDY ELIGIBILITY CRITERIA: Using Covidence, 2 reviewers screened for randomized controlled trials with ≥3 music interventions during pregnancy and applied either the Perceived Stress Scale score, State-Trait Anxiety Inventory score, Edinburgh Postnatal Depression Scale score, or blood pressure as outcomes. METHODS: The Cochrane risk-of-bias tool 2, the checklist to assess Trustworthiness in RAndomised Clinical Trials, and the reversed Cohen d were applied. This review was registered in the International Prospective Register of Systematic Reviews (registration number: CRD42022299950). RESULTS: From 251 detected records, 14 randomized controlled trials and 2375 pregnancies were included. Music interventions varied from 3 to 84 active or passive sessions with either patient-selected or preselected music and a duration of 10 to 60 minutes per session. Thereby, 2 of 4 studies observed a significant decrease in the Perceived Stress Scale, 8 of 9 studies observed a significant decrease in the State-Trait Anxiety Inventory, and 3 of 4 studies observed a significant decrease in the Edinburgh Postnatal Depression Scale. Blood pressure was significantly reduced in 3 of 4 randomized controlled trials. The Cochrane risk-of-bias tool 2 was "high" in 5 of 14 studies or "with concerns" in 9 of 14 studies. Stratifying the Cohen d in 14 intervention arms suggested a big effect in 234 of 469 mothers on blood pressure and in 244 of 489 mothers on maternal anxiety and a medium effect in 284 of 529 mothers on maternal anxiety. Small or very small effects on blood pressure, the Edinburgh Postnatal Depression Scale, and the Perceived Stress Scale were observed in 35 of 70, 136 of 277, and 374 of 784 mothers-to-be, respectively. CONCLUSION: Our study found a general positive effect of music interventions on maternal stress resilience. This was independent of the music but was influenced by the frequency and empathy of the performances. How far music interventions may improve postnatal development and skills of the offspring should be increasingly evaluated with follow-ups to interrupt vicious epigenetic circles during global pandemics, violent conflicts, and natural catastrophes.

Experiences of participant and public involvement in an international randomized controlled trial for people living with dementia and their informal caregivers.

BACKGROUND: This study was initiated and co-designed by a Participant and Public Involvement (PPI) group attached to HOMESIDE, a randomized controlled trial that investigated music and reading interventions for people living with dementia and their family caregivers across five countries: Australia, Germany, Norway, Poland, and the UK. The aim was to capture experiences of PPI across the five countries, explore the benefits and challenges of PPI in dementia research, and identify contributions made to the study. METHODS: We surveyed PPI members and academic researchers who collaborated on the HOMESIDE study. The survey was co-designed through consultation with PPI members and academics, alongside a small scoping literature review. Survey questions covered four topics: (1) expectations for PPI, (2) perceived contributions of PPI to the research study, (3) benefits and challenges of PPI, and (4) recommendations for future PPI in dementia research. RESULTS: There were 23 responses, representing 50% of the PPI members (n = 16) and 29% of academics (n = 7). PPI was found to be beneficial to the research and individuals involved. Contributions to the research included supporting recruitment and publicity, advising on the design of participant-facing materials, guiding the design and delivery of the interventions, and identifying cultural differences affecting research delivery. PPI members benefited from building connections, sharing experiences and receiving support, learning about dementia and research, and gaining new unexpected experiences. Academics learned about the realities of living with dementia, which they felt informed and grounded their work. Several challenges were identified, including the need for clear expectations and objectives, inconsistency of PPI members across research stages, limitations of meeting online versus in-person, scheduling difficulties, and language barriers. CONCLUSIONS: This study identifies important considerations for implementing PPI within dementia studies and international healthcare research more broadly. Our findings guided the development of five recommendations: (1) involve PPI members as early as possible and throughout the research process; (2) create a space for constructive criticism and feedback; (3) have clear tasks, roles, and expectations for PPI members; (4) involve PPI members with a diverse range of experiences and backgrounds; and (5) embed infrastructure and planning to support PPI.

Participant and Public Involvement (PPI) brings the knowledge of those with lived experience into research to improve research relevance and delivery. Our international study, called HOMESIDE, explored the benefits of music and reading activities for people with dementia and their family caregivers across five countries: Australia, Germany, Norway, Poland, and the UK. The study's PPI members included people with dementia, family carers, and healthcare professionals, who met regularly with the research team throughout the 3-year study. The current article reports the findings of a co-designed survey about PPI within HOMESIDE. Initiated by the HOMESIDE PPI members, we carried out a survey of PPI members and academics who worked on the study to learn about the unique experiences, perspectives, and contributions of PPI across the international research team.Our findings show that PPI helped to publicize the study, improved recruitment of research participants, and informed delivery of the interventions. Another important outcome was learning from each other; PPI members learned about dementia research and academics learned about the realities of living with dementia. However, the survey also highlighted challenges, including managing expectations, scheduling difficulties, and language barriers.To support PPI in future dementia research, we highlight five recommendations: (1) involve PPI members as early as possible and throughout the research process; (2) create a space for constructive criticism and feedback; (3) have clear tasks, roles, and expectations for PPI members; (4) involve PPI members with a diverse range of experiences and backgrounds; and (5) embed infrastructure and planning to support PPI.

Scoping Review of Music Interventions Aimed at Improving Reading Skills in Children with Specific Learning Disorders in Reading.

An emerging body of research utilizes music in the treatment of children with specific learning disorders in reading. However, greater understanding of music interventions is necessary for efficient application of music to address children's specific reading needs. Therefore, this scoping review aimed to identify the key musical concepts used to improve reading skills. Intervention studies were identified through online searches of databases and hand searching of primary journals in music therapy, and 12 studies met the inclusion criteria. For the 12 studies, auditory processing, phonological processing, and temporal processing were the underlying mechanisms identified in the interventions. Most of the interventions presented rhythmic activities for the purpose of improving reading accuracy. The results of this study highlight the lack of specific descriptions for the musical elements used within music interventions targeting reading skills. In addition, due to the diversity of the terms used to describe the music interventions, it was difficult to compare the effectiveness of these interventions on reading accuracy, comprehension skills, and fluency. Therefore, future studies are needed to articulate clear rationales for how musical elements can be used in music interventions to treat specific reading disabilities in children.

Home-based family caregiver-delivered music and reading interventions for people living with dementia (HOMESIDE trial): an international randomised controlled trial.

Background: Music interventions provided by qualified therapists within residential aged care are effective at attenuating behavioural and psychological symptoms (BPSD) of people with dementia (PwD). The impact of music interventions on dementia symptom management when provided by family caregivers is unclear. Methods: We implemented a community-based, large, pragmatic, international, superiority, single-masked randomised controlled trial to evaluate if caregiver-delivered music was superior to usual care alone (UC) on reducing BPSD of PwD measured by the Neuropsychiatric Inventory-Questionnaire (NPI-Q). The study included an active control (reading). People with dementia (NPI-Q score ≥6) and their caregiver (dyads) from one of five countries were randomly allocated to caregiver-delivered music, reading, or UC with a 1:1:1 allocation stratified by site. Caregivers received three online protocolised music or reading training sessions delivered by therapists and were recommended to provide five 30-min reading or music activities per week (minimum twice weekly) over 90-days. The NPI-Q severity assessment of PwD was completed online by masked assessors at baseline, 90- (primary) and 180-days post-randomisation and analysed on an intention-to-treat basis using a likelihood-based longitudinal data analysis model. ACTRN12618001799246; ClinicalTrials.govNCT03907748. Findings: Between 27th November 2019 and 7th July 2022, we randomised 432 eligible of 805 screened dyads (music n = 143, reading n = 144, UC n = 145). There was no statistical or clinically important difference in the change from baseline BPSD between caregiver-delivered music (-0.15, 95% CI -1.41 to 1.10, p = 0.81) or reading (-1.12, 95% CI -2.38 to 0.14, p = 0.082) and UC alone at 90-days. No related adverse events occurred. Interpretation: Our findings suggested that music interventions and reading interventions delivered by trained caregivers in community contexts do not decrease enduring BPSD symptoms. Funding: Our funding was provided by National Health and Medical Research Council, Australia; The Research Council of Norway; Federal Ministry of Education and Research, Germany; National Centre for Research and Development, Poland; Alzheimer's Society, UK, as part of the Joint Programme for Neurodegenerative Diseases consortia scheme.

Clinical music interventions and music therapy in dermatology.

Music interventions in medicine have been shown to reduce anxiety and depression, decrease pain, and improve quality of life; however, a review of clinical music interventions in dermatology is lacking. Studies have shown that playing music for patients undergoing dermatologic procedures (Mohs surgery and anesthetic injections) can decrease pain and anxiety. Patients with pruritic conditions-such as psoriasis, neurodermatitis, atopic dermatitis, contact eczema, and situations requiring hemodialysis-have exhibited decreased levels of disease burden and pain when listening to preferred music, pre-chosen music, and live music. Studies suggest that listening to certain types of music may also alter serum cytokines, affecting the allergic wheal response. Additional research is necessary to determine the full potential and practical applications for clinical music interventions in dermatology. Future research should focus on targeting skin conditions that may benefit from the psychological, inflammatory, and immune effects of music.

The acceptability, adoption, and feasibility of a music application developed using participatory design for home-dwelling persons with dementia and their caregivers. The "Alight" app in the LIVE@Home.Path trial.

Background: Music interventions for persons with dementia can improve health and interaction with caregivers, yet the reach is often restricted to institutions. We describe the participatory design process of a prototype music application for patients affiliated with a gerontopsychiatric hospital and evaluate the acceptability, adoption, and feasibility of use for dyads of home-dwelling persons with dementia and their informal caregivers. Methods: The application "Alight" was developed following an iterative, expert-driven participatory design approach, which includes a requirement elicitation phase and two rounds of prototyping and testing in real-world settings. End users and stakeholders were involved in all steps, that is, workshops, interviews, field observation, ethnographic inquiries, and beta testing sessions with music therapists, patients, and caregivers in collaboration with a commercial music and technology company. The last prototyping and testing took place in the LIVE@Home.Path trial, a stepped-wedge multicomponent randomized controlled trial to improve resource utilization and caregiver burden in municipal dementia care during 2019-2021. Results: Mean age of the person with dementia in the LIVE@Home.Path trial was 82 years, 62% were female, and the majority had Alzheimer's dementia (44%) of mild severity (71%). Sixty-three dyads were offered Alight in the multicomponent intervention, of which 13% (n = 8) accepted use. The dyads accepting Alight did not differ in demographic and clinical characteristics compared to those not interested. The feasibility was high among those accepting Alight, 75% (n = 6) reported a positive impact on mood, 50% (n = 4) experienced a positive impact on activity, and 50% (n = 4) gooduser-friendliness. The adoption was high with daily use or use several times a week reported by 63% (n = 5). Obstacles emerged when updating the application in homes without wireless Wi-Fi, and some participants were unfamiliar with using touchscreens. Conclusion: The feasibility and adoption of the application were high and accepting dyads did not differ on demographic and clinical variables from those not reached. This suggests a high potential for utilization in dementia care. This study contributes methodologically to the field of participatory design and mHealth interventions by demonstrating a specific design approach that throughout the process successfully involved researchers, industry partners, health care practitioners, and end users.

Music Interventions and Delirium in Adults: A Systematic Literature Review and Meta-Analysis.

Delirium is a neuropsychiatric syndrome represented by an acute disturbance in attention, awareness and cognition, highly prevalent in older, and critically ill patients, and associated with poor outcomes. This review synthesized existing evidence on the effectiveness of music interventions on delirium in adults, and music interventions (MIs), psychometric assessments and outcome measures used. We searched MEDLINE, PsychINFO, SCOPUS, Clinical Trials and CENTRAL for quantitative designs comparing any MIs to standard care or another intervention. From 1150 studies 12 met the inclusion criteria, and 6 were included in the meta-analysis. Narrative synthesis showed that most studies focused on prevention, few assessed delirium severity, with the majority of studies reporting beneficial effects. The summary relative risk for incident delirium comparing music vs. no music in postsurgical and critically ill older patients was 0.52 (95% confidential interval (CI): 0.20−1.35, I2 = 79.1%, heterogeneity <0.0001) for the random effects model and 0.47 (95% CI: 0.34−0.66) using the fixed effects model. Music listening interventions were more commonly applied than music therapy delivered by credentialed music therapists, and delirium assessments methods were heterogeneous, including both standardized tools and systematic observations. Better designed studies are needed addressing effectiveness of MIs in specific patient subgroups, exploring the correlations between intervention-types/dosages and delirium symptoms.

A systematic review of music interventions for the cognitive and behavioural symptoms of mild cognitive impairment (non-dementia).

Music interventions may represent an effective approach to improving symptoms and delaying progression of MCI to dementia. This review identified nine studies (8 RCT's, 1 observational study) that explored the benefits of music interventions to those with MCI. Studies included five music-playing interventions (sample size (n) ranged from 35 to 201, age ranged from 62 to 94), one music listening intervention (n = 100, mean age = 77 (music intervention) mean age = 76 (dance intervention), one music with movement intervention (n = 16, age range 65-84 years) and two music reminiscence interventions (n = 68; 72, age range = 60-85 years). Only individuals with a clinical diagnosis of MCI were included, no individuals with a diagnosis of dementia were included. Studies were limited due to their sample size, failure to consider confounding variables (i.e. socialization), inconsistency with therapist led sessions, failure to match conditions across interventions, limited follow-up period post-intervention and the tendency to focus on depression exclusively as a measure of behavioural symptoms. Different types of music interventions have differential results on cognitive and behavioural symptoms. The different pattern of brain activation and cognitive abilities which support each type of music activity (e.g. listening vs playing music) may offer some explanation towards these differences. A standardised protocol is needed for each type of music intervention to address how music interventions are studied, taking these limitations into consideration.

Isn't There Room for Music in Chronic Pain Management?

Chronic pain with its comorbidities, such as depression, insomnia, and social deprivation, is a major cause of disability and health-economic burden. Insufficient response to pain medication and potentially serious adverse effects have led the majority of chronic pain patients to seek relief from non-pharmacological remedies. Along with this trend, pain research has paid increasing interest in critical evaluation of various complementary treatments. Music-based treatments have emerged as an efficacious and safe means to enhance the management of acute and chronic pain. We review the current position of music-based interventions in the treatment of chronic pain and present explanations for the analgesic effects of music through modulation of the primary nociception and discuss the contribution of the mesolimbic dopaminergic system to the affective component of pain perception. We propose ways to translate the novel theoretical understanding into clinical practice in different health care settings, primary health care in particular, and discuss the preconditions of successful implementation. We argue that music interventions provide low-cost, easily applicable complementary pain treatments not requiring heavy utilization of health care resources. Finally, we provide research and quality improvement frameworks and make suggestions to cover the gaps of existing evidence. PERSPECTIVE: This article addresses the current evidence for analgesic effects of music interventions, discusses its neurobiological basis and evaluates potential use of music in treating chronic pain patients in different health care settings. We also propose directions for future research to cover shortages in the currently published data.

Effects of music intervention on sleep quality of older adults: A systematic review and meta-analysis.

BACKGROUND: Music interventions have several benefits for sleep quality. However, the effects of music interventions on sleep quality in older adults are controversial. OBJECTIVE: To summarize and evaluate the efficacy of music interventions on sleep quality in older adults. METHODS: The Cochrane Library, Embase, PubMed, Web of Science and Chinese National Knowledge Infrastructure (CNKI) were systematically retrieved until June 2020, updated on March 13, 2021. Both experimental and quasi-experimental studies were included if they evaluated the efficacy of music interventions on sleep outcomes in older adults. The methodological quality was assessed by the Cochrane RoB 2.0 and ROBINS-I Tool. The random effects models and effect measure (MD) were adopted, and sensitivity analysis by omitting each study was conducted to explore the source of heterogeneity. RESULTS: A total of 489 participants from 9 studies met the inclusion criteria. 6 studies were included in meta-analysis and sensitivity analysis, and 3 studies were included in the qualitative analysis. Main concerns about risk of bias were lack of blinding participants and investigators, and confounding factors might exist in non-RCTs. The Post-hoc meta-analysis indicated that music interventions might have a positive effect on sleep quality [MD = -2.64, 95 % CI (-3.76, -1.53), p <  0.001; I2 = 75.0 %]. Only one study evaluated adverse events and reported zero discomfort. CONCLUSIONS: The results indicated that music interventions might be beneficial for improving sleep quality, especially in sleep latency, sleep duration, sleep efficiency and sleep of daytime dysfunction in elderly individuals.

Tactile Low Frequency Vibration in Dementia Management: A Scoping Review Protocol.

Dementia is a growing issue in modern society. Non-pharmacological interventions such as music are suggested as the primary methods for symptom management. Therapeutic potential may also be found in sound/mechanical low frequency vibrations (LFV) that share the core characteristics of music, but these are lesser understood. The aim of the proposed scoping review is to explore the responses of persons with dementia to LFV, e.g., vibroacoustic therapy or whole-body vibration. The scoping review will follow the Joanna Briggs Institute methodology guidelines. An extensive search in BMC, CINAHL, Cochrane Central Register of Controlled Trials, EMBASE, ERIC, MEDLINE (OvidSP), Pedro, ProQuest Central, PsycINFO, Scopus, Web of Science, and grey literature sources in Clinical Trials, Current Controlled Trials, Google Scholar, and manual search of relevant journals is planned to find all relevant research papers. The paper selection, full-text assessment, and data extraction will be performed by two independent reviewers. Participants' responses to the interventions and the experiment designs, including methodological challenges, will be analysed and compared. Results may highlight potential gaps in reporting and comparing sound and mechanical vibration approaches and promote better understanding of their potential for managing the symptoms of dementia. Furthermore, the possible relationships between LFV and music-based interventions may become clearer.

The effect of musical interventions in improving short-term pain outcomes following total knee replacement: a meta-analysis and systematic review.

BACKGROUND: A growing number of patients continue to receive total knee replacement (TKR) surgery. Nevertheless, such surgeries result in moderate to severe postoperative pain and difficulty in managing it. Musical interventions are regarded as a type of multimodal analgesia, achieving beneficial results in other clinical treatments. This study aims to evaluate the effect of musical interventions in improving short-term pain outcomes following TKR in order to determine a more reasonable and standard way of delivering musical intervention. METHODS: A systematic search was conducted to identify available and relevant randomized controlled trials (RCTs) regarding musical interventions compared against non-musical interventions in patients treated with TKR in Embase, MEDLINE, Cochrane Library, Web of Science, CNKI, and Wanfang Med Online up to 8 January 2020. The authors independently assessed study eligibility and risk of bias and collected the outcomes of interest to analyze. The statistical analysis was conducted using the Review Manager (RevMan) version 5.30 software. RESULTS: Eight RCTs comprised of 555 patients satisfied the inclusion criteria and were enrolled in the present study. The results showed no significant difference between the music and control groups in pain of the visual analog scale (VAS), during postoperative recovery room, back to the ward after surgery; anxiety degree of VAS; heart rate; respiratory rate; oxygen saturation; blood pressure, systolic blood pressure, and diastolic blood pressure. Nevertheless, significant differences were observed between the two groups in average increase in continuous passive motion (CPM) angles and LF/HF ratio (one kind index of heart rate variability). CONCLUSIONS: Musical interventions fail to demonstrate an obvious effect in improving short-term pain outcomes following TKR. A reasonable standardization of musical interventions, including musical type, outcome measures used, outcomes measured, duration, timing and headphones or players, may improve pain outcomes with certain advantages and should be further explored after TKR.

The impact of a community-based music intervention on the health and well-being of young people: A realist evaluation.

In recent years, music-based interventions have been utilised as a tool for improving public health, reducing inequalities and promoting well-being of young people. Although some researchers have begun to draw links between music-related interventions and positive health outcomes, there is little understanding as to how such effects are produced. Realist evaluations-understanding what works, for whom and under what circumstances-are a particularly apt means by which we can open this 'black box'. In this paper, we use a realist evaluation to assess a community-based music initiative designed and implemented to support the well-being of disadvantaged young people in Scotland. In order to gain perspectives on the range of contextual characteristics, mechanisms and outcomes, we collected quantitative and qualitative data in the form of pre- and post-questionnaires, as well as conducting interviews with beneficiaries and stakeholders. Our findings show that the intervention achieved a positive impact on the self-confidence, well-being and engagement of disadvantaged young people. This impact was achieved via an approach personally tailored to the individual needs of the young people; and an organisational environment characterised by trust, whereby young people felt safe to express themselves.

Effects of music interventions on stress-related outcomes: a systematic review and two meta-analyses.

Music interventions are used for stress reduction in a variety of settings because of the positive effects of music listening on both physiological arousal (e.g., heart rate, blood pressure, and hormonal levels) and psychological stress experiences (e.g., restlessness, anxiety, and nervousness). To summarize the growing body of empirical research, two multilevel meta-analyses of 104 RCTs, containing 327 effect sizes and 9,617 participants, were performed to assess the strength of the effects of music interventions on both physiological and psychological stress-related outcomes, and to test the potential moderators of the intervention effects. Results showed that music interventions had an overall significant effect on stress reduction in both physiological (d = .380) and psychological (d = .545) outcomes. Further, moderator analyses showed that the type of outcome assessment moderated the effects of music interventions on stress-related outcomes. Larger effects were found on heart rate (d = .456), compared to blood pressure (d = .343) and hormone levels (d = .349). Implications for stress-reducing music interventions are discussed.

Music Interventions for Anxiety in Pregnant Women: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Prenatal anxiety is extremely common and may result in adverse effects on both the mother and the baby. Music interventions have been used to reduce anxiety in various medical patients and in pregnant women during childbirth. This study aims to assess the clinical efficacy of music interventions in women during pregnancy rather than during labor. Seven databases were searched from inception to September 2019 without language restrictions. We included only randomized controlled trials that compared music intervention and control groups for anxiety reduction in pregnant women. We used the revised Cochrane risk-of-bias tool (RoB 2.0) for quality assessment. Finally, 11 studies with 1482 participants were included. The pooled meta-analysis results showed that music interventions significantly decreased anxiety levels (standardized mean difference (SMD), -0.42; 95% confidence interval (CI), -0.83 to -0.02; I2 = 91%). Moreover, subgroup analysis showed that listening to music at home had significant anxiolytic benefits (SMD, -0.28; 95% CI, -0.47 to -0.08; I2 = 0%). However, meta-regression revealed a nonsignificant trend for increase in the anxiety-reducing effects of music interventions with increasing maternal age. In conclusion, music interventions may be beneficial in reducing anxiety and may be applied in pregnant women.

Music Interventions for Dementia and Depression in ELderly care (MIDDEL): protocol and statistical analysis plan for a multinational cluster-randomised trial.

INTRODUCTION: In older adults, dementia and depression are associated with individual distress and high societal costs. Music interventions such as group music therapy (GMT) and recreational choir singing (RCS) have shown promising effects, but their comparative effectiveness across clinical subgroups is unknown. This trial aims to determine effectiveness of GMT, RCS and their combination for care home residents and to examine heterogeneity of treatment effects across subgroups. METHODS AND ANALYSIS: This large, pragmatic, multinational cluster-randomised controlled trial with a 2×2 factorial design will compare the effects of GMT, RCS, both or neither, for care home residents aged 65 years or older with dementia and depressive symptoms. We will randomise 100 care home units with ≥1000 residents in total across eight countries. Each intervention will be offered for 6 months (3 months 2 times/week followed by 3 months 1 time/week), with extension allowed if locally available. The primary outcome will be the change in the Montgomery-Åsberg Depression Rating Scale score at 6 months. Secondary outcomes will include depressive symptoms, cognitive functioning, neuropsychiatric symptoms, psychotropic drug use, caregiver burden, quality of life, mortality and costs over at least 12 months. The study has 90% power to detect main effects and is also powered to determine interaction effects with gender, severity and socioeconomic status. ETHICS AND DISSEMINATION: Ethical approval has been obtained for one country and will be obtained for all countries. Results will be presented at national and international conferences and published in scientific journals. TRIAL REGISTRATION NUMBERS: NCT03496675; Pre-results, ACTRN12618000156280.

A systematic review of the use of music interventions to improve outcomes for patients undergoing hip or knee surgery.

AIM: To examine the effectiveness of music as an adjunct treatment for pain, anxiety, and/or postoperative delirium, for patients undergoing hip or knee surgery. BACKGROUND: Patients undergoing hip or knee surgery are known to experience pain and anxiety before and after surgery and be prone to postoperative delirium. DESIGN: Quantitative systematic review. DATA SOURCES: CENTRAL, Embase, Ovid MEDLINE, CINAHL, and PsycINFO databases were systematically searched without time limits (to June 2018). REVIEW METHODS: A systematic search yielded 10 randomized controlled trials and quasi-experimental designs. Studies were appraised using the Cochrane Risk of Bias Tool. Data were extracted using the Effective Practice and Organization of Care data extraction tool. RESULTS: Mixed results were found for the effect of music on anxiety, pain, and postoperative delirium in patients undergoing hip or knee surgery. Six of 10 included studies provided evidence that music can improve anxiety, pain, or postoperative delirium outcomes for patients undergoing hip or knee surgery. Music effectively reduced anxiety in one of three studies. Three of seven studies reported benefits of music for reducing postoperative pain. Positive effects of music on postoperative delirium were reported in all three studies that evaluated this outcome. Within group improvements were observed in many of the studies. CONCLUSION: Music has the potential to improve outcomes of anxiety, pain, and postoperative delirium, for patients undergoing hip or knee surgery. The low number of studies found indicates results should be treated with caution. Further studies are required to provide strong evidence generalizable to a broader population.
