Effectiveness and implementation of lower-intensity weight management interventions delivered by the non-specialist workforce in postnatal women: a mixed-methods systematic review.

Lower-intensity interventions delivered in primary and community care contacts could provide more equitable and scalable weight management support for postnatal women. This mixed-methods systematic review aimed to explore the effectiveness, implementation, and experiences of lower-intensity weight management support delivered by the non-specialist workforce. We included quantitative and qualitative studies of any design that evaluated a lower-intensity weight management intervention delivered by non-specialist workforce in women up to 5 years post-natal, and where intervention effectiveness (weight-related and/or behavioural outcomes), implementation and/or acceptability were reported. PRISMA guidelines were followed, and the review was prospectively registered on PROSPERO (CRD42022371828). Nine electronic databases were searched to identify literature published between database inception to January 2023. This was supplemented with grey literature searches and citation chaining for all included studies and related reviews (completed June 2023). Screening, data extraction and risk of bias assessments were performed in duplicate. Risk of bias was assessed using the Joanna Briggs Institute appraisal tools. Narrative methods were used to synthesise outcomes. Seven unique studies described in 11 reports were included from the Netherlands (n = 2), and the United Kingdom, Germany, Taiwan, Finland, and the United States (n = 1 each). All studies reported weight-related outcomes; four reported diet; four reported physical activity; four reported intervention implementation and process outcomes; and two reported intervention acceptability and experiences. The longest follow-up was 13-months postnatal. Interventions had mixed effects on weight-related outcomes: three studies reported greater weight reduction and/or lower postnatal weight retention in the intervention group, whereas four found no difference or mixed effects. Most studies reporting physical activity or diet outcomes showed no intervention effect, or mixed effects. Interventions were generally perceived as acceptable by women and care providers, although providers had concerns about translation into routine practice. The main limitations of the review were the limited volume of evidence available, and significant heterogeneity in interventions and outcome reporting which limited meaningful comparisons across studies. There is a need for more intervention studies, including process evaluations, with longer follow-up in the postnatal period to understand the role of primary and community care in supporting women's weight management. Public Health Wales was the primary funder of this review.

Views of Service Users, Their Family or Carers, and Health Care Professionals on Telerehabilitation for People With Neurological Conditions in Ghana: Qualitative Study.

BACKGROUND: Up to 50% of people in low- and middle-income countries do not receive the rehabilitation they require. Telerehabilitation has the potential to improve access to neurorehabilitation services especially in low- and middle-income countries. Although there are reports of the barriers and facilitators to telerehabilitation in such settings, almost all are anecdotal. Furthermore, family or carers have a significant influence on the adoption and success of telerehabilitation, but their views have not been reported. OBJECTIVE: This study aimed to investigate the views of service users, their family or carers, and health care professionals (HCPs) on telerehabilitation for people with neurological conditions in Ghana. METHODS: Two focus groups were held at Komfo Anokye Hospital in Kumasi, Ghana: one in person for service users (n=11) and their family or carers (n=9), conducted in the Ghanaian language of Twi, and one hybrid for HCPs (n=18) conducted in English. The mean (SD) age of the service users was 59.8 (8.6) years; 5 users had a stroke and 6 had Parkinson disease. The HCP group consisted of 7 speech and language therapists, 3 physiotherapists, 3 occupational therapists, 3 medical staff, 1 nurse, and 1 industry representative. Focus groups were semi-structured and explored previous experiences of telerehabilitation, perceived benefits and challenges, and solutions to overcome these challenges. Focus groups were audio transcribed, and the service user transcript was translated into English. The resulting transcripts were analyzed using thematic analysis. RESULTS: Overall, participants were positive about the role of telerehabilitation but recommended hybrid delivery, with in-person rehabilitation in the early stages and telerehabilitation in the later stages. In relation to telerehabilitation in Ghana, there were 3 main themes: benefits, challenges or barriers, and implementation. Benefits included the convenience and lower cost for service users, the higher dose of therapy possible, and increased access for people in remote areas. However, challenges included lack of a stable internet connection, cost of phones and data packages, and low levels of literacy. Implementation issues included cultural relevance, information governance, and the platform used to deliver telerehabilitation, with most participants being familiar with WhatsApp. CONCLUSIONS: Telerehabilitation has the potential to be a useful method of delivering rehabilitation to people with neurological conditions in Ghana, especially in a hybrid rehabilitation model with telerehabilitation augmenting in-person sessions. However, many people were unaware of telerehabilitation, and challenges such as a reliable internet connection, cultural relevance, and costs need to be addressed. Clinical trials of low-cost telerehabilitation interventions contextualized to the specific user group are required.

Strategies used for childhood chronic functional constipation: the SUCCESS evidence synthesis.

Background: Up to 30% of children have constipation at some stage in their life. Although often short-lived, in one-third of children it progresses to chronic functional constipation, potentially with overflow incontinence. Optimal management strategies remain unclear. Objective: To determine the most effective interventions, and combinations and sequences of interventions, for childhood chronic functional constipation, and understand how they can best be implemented. Methods: Key stakeholders, comprising two parents of children with chronic functional constipation, two adults who experienced childhood chronic functional constipation and four health professional/continence experts, contributed throughout the research. We conducted pragmatic mixed-method reviews. For all reviews, included studies focused on any interventions/strategies, delivered in any setting, to improve any outcomes in children (0-18 years) with a clinical diagnosis of chronic functional constipation (excluding studies of diagnosis/assessment) included. Dual reviewers applied inclusion criteria and assessed risk of bias. One reviewer extracted data, checked by a second reviewer. Scoping review: We systematically searched electronic databases (including Medical Literature Analysis and Retrieval System Online, Excerpta Medica Database, Cumulative Index to Nursing and Allied Health Literature) (January 2011 to March 2020) and grey literature, including studies (any design) reporting any intervention/strategy. Data were coded, tabulated and mapped. Research quality was not evaluated. Systematic reviews of the evidence of effectiveness: For each different intervention, we included existing systematic reviews judged to be low risk of bias (using the Risk of Bias Assessment Tool for Systematic Reviews), updating any meta-analyses with new randomised controlled trials. Where there was no existing low risk of bias systematic reviews, we included randomised controlled trials and other primary studies. The risk of bias was judged using design-specific tools. Evidence was synthesised narratively, and a process of considered judgement was used to judge certainty in the evidence as high, moderate, low, very low or insufficient evidence. Economic synthesis: Included studies (any design, English-language) detailed intervention-related costs. Studies were categorised as cost-consequence, cost-effectiveness, cost-utility or cost-benefit, and reporting quality evaluated using the consensus health economic criteria checklist. Systematic review of implementation factors: Included studies reported data relating to implementation barriers or facilitators. Using a best-fit framework synthesis approach, factors were synthesised around the consolidated framework for implementation research domains. Results: Stakeholders prioritised outcomes, developed a model which informed evidence synthesis and identified evidence gaps. Scoping review: 651 studies, including 190 randomised controlled trials and 236 primary studies, conservatively reported 48 interventions/intervention combinations. Effectiveness systematic reviews: studies explored service delivery models (n = 15); interventions delivered by families/carers (n = 32), wider children's workforce (n = 21), continence teams (n = 31) and specialist consultant-led teams (n = 42); complementary therapies (n = 15); and psychosocial interventions (n = 4). One intervention (probiotics) had moderate-quality evidence; all others had low to very-low-quality evidence. Thirty-one studies reported evidence relating to cost or resource use; data were insufficient to support generalisable conclusions. One hundred and six studies described implementation barriers and facilitators. Conclusions: Management of childhood chronic functional constipation is complex. The available evidence remains limited, with small, poorly conducted and reported studies. Many evidence gaps were identified. Treatment recommendations within current clinical guidelines remain largely unchanged, but there is a need for research to move away from considering effectiveness of single interventions. Clinical care and future studies must consider the individual characteristics of children. Study registration: This study is registered as PROSPERO CRD42019159008.

Between 5% and 30% of children experience constipation at some stage. In one-third of these children, this progresses to chronic functional constipation. Chronic functional constipation affects more children with additional needs. We aimed to find and bring together published information about treatments for chronic functional constipation, to help establish best treatments and treatment combinations. We did not cover assessment or diagnosis of chronic functional constipation. This project was guided by a 'stakeholder group', including parents of children with constipation, people who experienced constipation as children, and healthcare professionals/continence experts. We carried out a 'scoping review' and a series of 'systematic reviews'. Our 'scoping review' provides an overall picture of research about treatments, with 651 studies describing 48 treatments. This helps identify important evidence gaps. 'Systematic reviews' are robust methods of bringing together and interpreting research evidence. Our stakeholder group decided to structure our systematic reviews to reflect who delivered the interventions. We brought together evidence about how well treatments worked when delivered by families/carers (32 studies), the wider children's workforce (e.g. general practitioner, health visitor) (21 studies), continence teams (31 studies) or specialist consultant-led teams (42 studies). We also considered complementary therapies (15 studies) and behavioural strategies (4 studies). Care is affected by what is done and how it is done. We brought together evidence about different models of delivering care (15 studies), barriers and facilitators to implementation of treatments (106 studies) and costs (31 studies). Quality of evidence was mainly low to very low. Despite numerous studies, there was often insufficient information to support generalisable conclusions. Our findings generally agreed with current clinical guidelines. Management of childhood chronic functional constipation should be child-centred, multifaceted and adapted according to the individual child, their needs, the situation in which they live and the health-care setting in which they are looked after. Research is needed to address our identified evidence gaps.

Socioeconomic inequalities in vaccine uptake: A global umbrella review.

This global umbrella review aimed to synthesise evidence of socioeconomic inequalities in the uptake of routine vaccinations and identify the mechanisms that may contribute to the association. To our knowledge, no attempt has been made to synthesise the global body of systematic reviews across a variety of vaccines, geographical locations, and measures of SES. The inclusion criteria were as follows: studies assessing vaccination uptake according to education, income, occupation/employment, and/or area-level deprivation; any country or universally recommended routine vaccination (according to the WHO); qualitative or quantitative reviews, published 2011-present. The searches were performed in eight databases. The screening process followed PRISMA-E guidelines, each stage was performed by one reviewer, and a 10% sample checked by a second for consistency. Included reviews underwent data extraction, quality appraisal (AMSTAR-2), and narrative synthesis according to country-context. After deduplication, 9,163 reports underwent title and abstract screening, leaving 119 full texts to be assessed for eligibility. Overall, 26 studies were included in the umbrella review. Evidence for lower uptake amongst disadvantaged SES individuals was found in all 26 reviews. However, 17 reviews showed mixed results, as inverse associations were also identified (lower uptake for advantaged SES, and/or higher uptake for disadvantaged SES). Those that explored high-income countries had a greater prevalence of mixed findings than those focusing on low/middle-income countries. The two most frequently cited mechanisms were vaccination knowledge, and confidence in vaccination or vaccination providers. These mechanisms were often understood by review authors as varying by level of education. We find socioeconomic differences in routine vaccination uptake, but the association did not always follow a gradient. Whilst education may be associated with uptake globally, our study indicates that its role varies by country-context. A limitation is the overlap of some primary studies across the included systematic reviews.

A meta-ethnography of how children and young people with chronic non-cancer pain and their families experience and understand their condition, pain services, and treatments.

BACKGROUND: Chronic non-cancer pain in childhood is widespread, affecting 20% to 35% of children and young people worldwide. For a sizeable number of children, chronic non-cancer pain has considerable negative impacts on their lives and quality of life, and leads to increased use of healthcare services and medication. In many countries, there are few services for managing children's chronic non-cancer pain, with many services being inadequate. Fourteen Cochrane Reviews assessing the effects of pharmacological, psychological, psychosocial, dietary or physical activity interventions for managing children's chronic non-cancer pain identified a lack of high-quality evidence to inform pain management. To design and deliver services and interventions that meet the needs of patients and their families, we need to understand how children with chronic non-cancer pain and their families experience pain, their views of services and treatments for chronic pain, and which outcomes are important to them. OBJECTIVES: 1. To synthesise qualitative studies that examine the experiences and perceptions of children with chronic non-cancer pain and their families regarding chronic non-cancer pain, treatments and services to inform the design and delivery of health and social care services, interventions and future research. 2. To explore whether our review findings help to explain the results of Cochrane Reviews of intervention effects of treatments for children's chronic non-cancer pain. 3. To determine if programme theories and outcomes of interventions match children and their families' views of desired treatments and outcomes. 4. To use our findings to inform the selection and design of patient-reported outcome measures for use in chronic non-cancer pain studies and interventions and care provision to children and their families. The review questions are: 1. How do children with chronic non-cancer pain and their families conceptualise chronic pain? 2. How do children with chronic non-cancer pain and their families live with chronic pain? 3. What do children with chronic non-cancer pain and their families think of how health and social care services respond to and manage their child's chronic pain? 4. What do children with chronic non-cancer pain and their families conceptualise as 'good' chronic pain management and what do they want to achieve from chronic pain management interventions and services? SEARCH METHODS: Review strategy: we comprehensively searched 12 bibliographic databases including MEDLINE, CINAHL, PsycInfo and grey literature sources, and conducted supplementary searches in 2020. We updated the database searches in September 2022. SELECTION CRITERIA: To identify published and unpublished qualitative research with children aged 3 months to 18 years with chronic non-cancer pain and their families focusing on their perceptions, experiences and views of chronic pain, services and treatments. The final inclusion criteria were agreed with a patient and public involvement group of children and young people with chronic non-cancer pain and their families. DATA COLLECTION AND ANALYSIS: We conducted a qualitative evidence synthesis using meta-ethnography, a seven-phase, systematic, interpretive, inductive methodology that takes into account the contexts and meanings of the original studies. We assessed the richness of eligible studies and purposively sampled rich studies ensuring they addressed the review questions. Cochrane Qualitative Methods Implementation Group guidance guided sampling. We assessed the methodological limitations of studies using the Critical Appraisal Skills Programme tool. We extracted data on study aims, focus, characteristics and conceptual findings from study reports using NVivo software. We compared these study data to determine how the studies related to one another and grouped studies by pain conditions for synthesis. We used meta-ethnography to synthesise each group of studies separately before synthesising them all together. Analysis and interpretation of studies involved children with chronic non-cancer pain and their families and has resulted in theory to inform service design and delivery. Sampling, organising studies for synthesis, and analysis and interpretation involved our patient and public involvement group who contributed throughout the conduct of the review. We used the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach to assess our confidence in each review finding. We used a matrix approach to integrate our findings with existing Cochrane Reviews on treatment effectiveness for children's chronic non-cancer pain. MAIN RESULTS: We synthesised 43 studies sampled from 170 eligible studies reported in 182 publications. Included studies involved 633 participants. GRADE-CERQual assessments of findings were mostly high (n = 21, 58%) or moderate (n = 12, 33%) confidence with three (8%) low or very low confidence. Poorly managed, moderate or severe chronic non-cancer pain had profound adverse impacts on family dynamics and relationships; family members' emotions, well-being, autonomy and sense of self-identity; parenting strategies; friendships and socialising; children's education and future employment prospects; and parental employment. Most children and parents understood chronic non-cancer pain as having an underlying biological cause and wanted curative treatment. However, families had difficulties seeking and obtaining support from health services to manage their child's pain and its impacts. Children and parents felt that healthcare professionals did not always listen to their experiences and expertise, or believe the child's pain. Some families repeatedly visited health services seeking a diagnosis and cure. Over time, some children and families gave up hope of effective treatment. Outcomes measured within trials and Cochrane Reviews of intervention effects did not include some outcomes of importance to children and families, including impacts of pain on the whole family and absence of pain. Cochrane Reviews have mainly neglected a holistic biopsychosocial approach, which specifies the interrelatedness of biological, psychological and social aspects of illness, when selecting outcome measures and considering how chronic pain management interventions work. AUTHORS' CONCLUSIONS: We had high or moderate confidence in the evidence contributing to most review findings. Further research, especially into families' experiences of treatments and services, could strengthen the evidence for low or very low confidence findings. Future research should also explore families' experiences in low- to middle-income contexts; of pain treatments including opioid use in children, which remains controversial; and of social care services. We need development and testing of family-centred interventions and services acceptable to families. Future trials of children's chronic non-cancer pain interventions should include family-centred outcomes.

Interventions to tackle health inequalities in cardiovascular risks for socioeconomically disadvantaged populations: a rapid review.

INTRODUCTION: Cardiovascular disease (CVD) has shown significant health inequalities for people with low socioeconomic status associated with more risk factors. This review was to synthesize interventions that targeted CVD risks and outcomes among socioeconomically disadvantaged populations and to understand the impact associated with these interventions. SOURCES OF DATA: Cochrane CENTRAL, MEDLINE, Embase, PsycINFO and CINAHL were searched for records published in the last decade using a systematic search strategy, complemented by screening the reference lists and citation indexes. Nineteen studies were included and a narrative synthesis with the effect direction plot was undertaken in which studies, interventions, participants and outcomes were examined according to the intervention type focusing on behaviours, lifestyle, education, medication and monitoring. AREAS OF AGREEMENT: No universal definition of disadvantaged socioeconomic status was used with common factors relating to racial/ethnic minorities, low income and low or no health insurance. Mixed effects of interventions were reported on clinical outcomes including weight, body mass index, blood pressure, glycated haemoglobin and cholesterol. AREAS OF CONTROVERSY: Inconsistent effect was reported due to a large variety of settings, participants and intervention components although they are considered necessary to address the complex health needs of socioeconomically disadvantaged populations. GROWING POINTS: There is inadequate evidence to determine whether any of the intervention types are effective in optimising lipids management for socioeconomically disadvantaged populations. AREAS TIMELY FOR DEVELOPING RESEARCH: Research is needed with mixed evidence using real world evaluation and lived experience combined with health economic evaluation, on both mental and physical health outcomes.

Exploring the contribution of case study research to the evidence base for occupational therapy: a scoping review.

BACKGROUND: Case study research is generating interest to evaluate complex interventions. However, it is not clear how this is being utilized by occupational therapists or how feasible it is to contribute to the evidence base. This scoping review explores case study research within occupational therapy in terms of how it is defined, the methodological characteristics adopted, such as data collection and analysis, and the range of practice contexts in which it is applied. We consider the viability of case study research for contributing to our evidence base. METHODS: Opinion, text and empirical studies within an occupational therapy practice context were included. A three-step extensive search following Joanna Briggs Institute methodology was conducted in June 2020 and updated in July 2021 across ten databases, websites, peer-reviewed and grey literature from 2016 onwards. Study selection was completed by two independent reviewers. A data extraction table was developed and piloted and data charted to align with research questions. Data extraction was completed by one reviewer and a 10% sample cross checked by another. RESULTS: Eighty-eight studies were included in the review consisting of (n = 84) empirical case study and (n = 4) non-empirical papers. Case study research has been conducted globally, with a range of populations across different settings. The majority were conducted in a community setting (n = 48/84; 57%) with populations experiencing neurodevelopmental disorder (n = 32/84; 38%), stroke (n = 14/84;17%) and non-diagnosis specific (n = 13/84; 15%). Methodologies adopted quantitative (n = 42/84; 50%), mixed methods (n = 22/84; 26%) and qualitative designs (n = 20/84; 24%). However, identifying the methodology and 'case' was a challenge due to methodological inconsistencies. CONCLUSIONS: Case study research is useful when large-scale inquiry is not appropriate; for cases of complexity, early intervention efficacy, theory testing or when small participant numbers are available. It appears a viable methodology to contribute to the evidence base for occupation and health as it has been used to evaluate interventions across a breadth of occupational therapy practice contexts. Viability could be enhanced through consistent conduct and reporting to allow pooling of case data. A conceptual model and description of case study research in occupational therapy is proposed to support this. SYSTEMATIC REVIEW REGISTRATION: Open Science Framework 10.17605/OSF.IO/PCFJ6.

Experiences of Non-Pharmaceutical Primary Care Interventions for Common Mental Health Disorders in Socioeconomically Disadvantaged Groups: A Systematic Review of Qualitative Studies.

Common mental health disorders (CMDs) disproportionately affect people experiencing socioeconomic disadvantage. Non-pharmaceutical interventions, such as 'social prescribing' and new models of care and clinical practice, are becoming increasingly prevalent in primary care. However, little is known about how these interventions work and their impact on socioeconomic inequalities in health. Focusing on people experiencing socioeconomic disadvantage, this systematic review aims to: (1) explore the mechanisms by which non-pharmaceutical primary care interventions impact CMD-related health outcomes and inequalities; (2) identify the barriers to, and facilitators of, their implementation in primary care. This study is a systematic review of qualitative studies. Six bibliographic databases were searched (Medline, ASSIA, CINAHL, Embase, PsycInfo and Scopus) and additional grey literature sources were screened. The included studies were thematically analysed. Twenty-two studies were included, and three themes were identified: (1) agency; (2) social connections; (3) socioeconomic environment. The interventions were experienced as being positive for mental health when people felt a sense of agency and social connection. The barriers to effectiveness and engagement included socioeconomic deprivation and underfunding of community sector organisations. If non-pharmaceutical primary care interventions for CMDs are to avoid widening health inequalities, key socioeconomic barriers to their accessibility and implementation must be addressed.

Non-pharmaceutical primary care interventions to improve mental health in deprived populations: a systematic review.

BACKGROUND: Common mental health disorders are especially prevalent among people from socioeconomically disadvantaged backgrounds. Non-pharmaceutical primary care interventions, such as social prescribing and collaborative care, provide alternatives to pharmaceutical treatments for common mental health disorders, but little is known about the impact of these interventions for patients who are socioeconomically disadvantaged. AIM: To synthesise evidence for the effects of non-pharmaceutical primary care interventions on common mental health disorders and associated socioeconomic inequalities. DESIGN AND SETTING: Systematic review of quantitative primary studies published in English and undertaken in high-income countries. METHOD: Six bibliographic databases were searched and additional grey literature sources screened. Data were extracted onto a standardised proforma and quality assessed using the Effective Public Health Practice Project tool. Data were synthesised narratively and effect direction plots were produced for each outcome. RESULTS: Thirteen studies were included. Social-prescribing interventions were evaluated in 10 studies, collaborative care in two studies, and a new model of care in one study. Positive results (based on effect direction) were reported for the impact of the interventions on wellbeing in groups that were socioeconomically deprived. Inconsistent (mainly positive) results were reported for anxiety and depression. One study reported that people from the group with least deprivation, compared with the group with greatest deprivation, benefitted most from these interventions. Overall, study quality was weak. CONCLUSION: Targeting non-pharmaceutical primary care interventions at areas of socioeconomic deprivation may help to reduce inequalities in mental health outcomes. However, only tentative conclusions can be drawn from the evidence in this review and more-robust research is required.

Case study research: Building the occupational therapy evidence base one case at a time.

BACKGROUND: There is growing recognition in healthcare that evidence from randomised controlled trials may not be appropriate to answer the full spectrum of practice-based questions and a more pluralistic approach is needed. AIM: To consider the use of case study research in contributing to the occupational therapy evidence base. MATERIAL AND METHODS: A critical discussion of the current state of evidence-based practice in occupational therapy and exploration of a viable approach to case study research is used. RESULTS: Case study research can capture the context and complexity of occupational therapy practice. Cases can then be pooled to make a substantial contribution to the evidence base. CONCLUSIONS: Occupational therapists should consider the use of case study research to produce practice related, meaningful research. Journal editorial boards need to be mindful of the value of high-quality case study research when considering publication priorities in occupational therapy literature. SIGNIFICANCE: Highlights a changing landscape in the literature about how best to conduct research in health and social care, particularly for complex interventions and describes a pragmatic approach to case study research for occupational therapy.

A rapid priority setting exercise combining existing, emergent evidence with stakeholder knowledge identified broad topic uncertainties.

OBJECTIVES: The project aimed to rapidly identify priority topic uncertainties as a first step to identify future systematic review questions of pertinence to key international fecal incontinence (FI) stakeholders (patients, carers, health care professionals, policy makers and voluntary, community, or social enterprise representatives). The paper's aim is to share our methods, experience, and learning with other groups planning to deliver a rapid priority setting exercise. STUDY DESIGN AND SETTING: An evidence gap map incorporated three evidence streams: emerging evidence identified through horizon scanning; existing evidence identified through systematic searches of bibliographic databases; and FI stakeholder insights collected through an international survey. The evidence gap map was presented during an online workshop with stakeholders, where they shared their expertize to expand, refine, and rank topic uncertainties using ideation techniques, focus group discussions, consensus techniques, and online polling. RESULTS: The multistep methods used to deliver this priority setting exercise resulted in identification of broad priority topic uncertainties. The methods appear to have high acceptability and engagement with participants but await full evaluation. CONCLUSION: This project successfully followed robust methodology, building upon frameworks from published priority setting and evidence gap mapping projects while incorporating strong patient and public involvement components.

Oral nutritional interventions in frail older people who are malnourished or at risk of malnutrition: a systematic review.

BACKGROUND: Malnutrition worsens the health of frail older adults. Current treatments for malnutrition may include prescribed oral nutritional supplements, which are multinutrient products containing macronutrients and micronutrients. OBJECTIVE: To assess the effectiveness and cost-effectiveness of oral nutritional supplements (with or without other dietary interventions) in frail older people who are malnourished or at risk of malnutrition. DATA SOURCES: MEDLINE, EMBASE, Cochrane Library, Scopus, CINAHL (Cumulative Index to Nursing and Allied Health Literature) and grey literature were searched from inception to 13 September 2021. REVIEW METHODS: A systematic review and meta-analysis was conducted to evaluate the effectiveness and cost-effectiveness of oral nutritional supplements in frail older people (aged ≥ 65 years) who are malnourished or at risk of malnutrition (defined as undernutrition as per National Institute for Health and Care Excellence guidelines). Meta-analysis and network meta-analysis were undertaken, where feasible, along with a narrative synthesis. A cost-effectiveness review was reported narratively. A de novo model was developed using effectiveness evidence identified in the systematic review to estimate the cost-effectiveness of oral nutritional supplements. RESULTS: Eleven studies (n = 822 participants) were included in the effectiveness review, six of which were fully or partly funded by industry. Meta-analyses suggested positive effects of oral nutritional supplements compared with standard care for energy intake (kcal) (standardised mean difference 1.02, 95% confidence interval 0.15 to 1.88; very low quality evidence) and poor mobility (mean difference 0.03, p < 0.00001, 95% confidence interval 0.02 to 0.04; very low quality evidence) but no evidence of an effect for body weight (mean difference 1.31, 95% confidence interval -0.05 to 2.66; very low quality evidence) and body mass index (mean difference 0.54, 95% confidence interval -0.03 to 1.11; very low quality evidence). Pooled results for other outcomes were statistically non-significant. There was mixed narrative evidence regarding the effect of oral nutritional supplements on quality of life. Network meta-analysis could be conducted only for body weight and grip strength; there was evidence of an effect for oral nutritional supplements compared with standard care for body weight only. Study quality was mixed; the randomisation method was typically poorly reported. One economic evaluation, in a care home setting, was included. This was a well-conducted study showing that oral nutritional supplements could be cost-effective. Cost-effectiveness analysis suggested that oral nutritional supplements may only be cost-effective for people with lower body mass index (< 21 kg/m2) using cheaper oral nutritional supplements products that require minimal staff time to administer. LIMITATIONS: The review scope was narrow in focus as few primary studies used frailty measures (or our proxy criteria). This resulted in only 11 included studies. The small evidence base and varied quality of evidence meant that it was not possible to determine accurate estimates of the effectiveness or cost-effectiveness of oral nutritional supplements. Furthermore, only English-language publications were considered. CONCLUSIONS: Overall, the review found little evidence of oral nutritional supplements having significant effects on reducing malnutrition or its adverse outcomes in frail older adults. FUTURE WORK: Future research should focus on independent, high-quality, adequately powered studies to investigate oral nutritional supplements alongside other nutritional interventions, with longer-term follow-up and detailed analysis of determinants, intervention components and cost-effectiveness. STUDY REGISTRATION: This study is registered as PROSPERO CRD42020170906. FUNDING: This project was funded by the National Institute for Health and Care Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 26, No. 51. See the NIHR Journals Library website for further project information.

WHAT WAS THE QUESTION?: Malnutrition, in the form of undernutrition, is very common in frail older people. Dietary advice is recommended (e.g. adding nutrients to meals) for older adults who are malnourished, while powdered or liquid supplements (oral nutritional supplements) can be prescribed to those who are malnourished or at risk of becoming malnourished. In this study, we reviewed previous studies to see if oral nutritional supplements (as a form of dietary support) work at reducing malnutrition in frail older adults and whether or not they are value for money. WHAT DID WE DO?: We searched for studies up to September 2021 on frail older people who were at risk of malnutrition or were malnourished in care homes, hospitals or the community in any country. We included studies that measured malnutrition and the consequences of malnutrition, quality of life, survival, costs and hospitalisations. We assessed the difference in malnutrition between those receiving oral nutritional supplements and those receiving usual care or other dietary (or nutritional) interventions. We also looked at the value for money of oral nutritional supplements. WHAT DID WE FIND?: We found 12 studies (11 studies looking at whether the supplements worked and one study looking at value for money). Most of which were of low quality, and many were funded by industry. Studies often did not report on longer-term effects, or how older people felt about the supplements. There was no clear or strong evidence that oral nutritional supplements worked or were value for money in reducing malnutrition or its consequences (such as the ability to perform everyday tasks). WHAT DOES THIS MEAN?: There is weak evidence for oral nutritional supplements in frail older adults. Future high-quality studies should be independent, assess longer-term effects, and have better reporting on factors that influence the impacts of oral nutritional supplements.

Interventions for perceptual disorders following stroke.

BACKGROUND: Perception is the ability to understand information from our senses. It allows us to experience and meaningfully interact with our environment. A stroke may impair perception in up to 70% of stroke survivors, leading to distress, increased dependence on others, and poorer quality of life. Interventions to address perceptual disorders may include assessment and screening, rehabilitation, non-invasive brain stimulation, pharmacological and surgical approaches. OBJECTIVES: To assess the effectiveness of interventions aimed at perceptual disorders after stroke compared to no intervention or control (placebo, standard care, attention control), on measures of performance in activities of daily living.  SEARCH METHODS: We searched the trials registers of the Cochrane Stroke Group, CENTRAL, MEDLINE, Embase, and three other databases to August 2021. We also searched trials and research registers, reference lists of studies, handsearched journals, and contacted authors. SELECTION CRITERIA: We included randomised controlled trials (RCTs) of adult stroke survivors with perceptual disorders. We defined perception as the specific mental functions of recognising and interpreting sensory stimuli and included hearing, taste, touch, smell, somatosensation, and vision. Our definition of perception excluded visual field deficits, neglect/inattention, and pain. DATA COLLECTION AND ANALYSIS: One review author assessed titles, with two review authors independently screening abstracts and full-text articles for eligibility. One review author extracted, appraised, and entered data, which were checked by a second author. We assessed risk of bias (ROB) using the ROB-1 tool, and quality of evidence using GRADE.  A stakeholder group, comprising stroke survivors, carers, and healthcare professionals, was involved in this review update. MAIN RESULTS: We identified 18 eligible RCTs involving 541 participants. The trials addressed touch (three trials, 70 participants), somatosensory (seven trials, 196 participants) and visual perception disorders (seven trials, 225 participants), with one (50 participants) exploring mixed touch-somatosensory disorders. None addressed stroke-related hearing, taste, or smell perception disorders. All but one examined the effectiveness of rehabilitation interventions; the exception evaluated non-invasive brain stimulation. For our main comparison of active intervention versus no treatment or control, one trial reported our primary outcome of performance in activities of daily living (ADL):  Somatosensory disorders: one trial (24 participants) compared an intervention with a control intervention and reported an ADL measure.  Touch perception disorder: no trials measuring ADL compared an intervention with no treatment or with a control intervention.  Visual perception disorders: no trials measuring ADL compared an intervention with no treatment or control.  In addition, six trials reported ADL outcomes in a comparison of active intervention versus active intervention, relating to somatosensation (three trials), touch (one trial) and vision (two trials).   AUTHORS' CONCLUSIONS: Following a detailed, systematic search, we identified limited RCT evidence of the effectiveness of interventions for perceptual disorders following stroke. There is insufficient evidence to support or refute the suggestion that perceptual interventions are effective. More high-quality trials of interventions for perceptual disorders in stroke are needed. They should recruit sufficient participant numbers, include a 'usual care' comparison, and measure longer-term functional outcomes, at time points beyond the initial intervention period. People with impaired perception following a stroke should continue to receive neurorehabilitation according to clinical guidelines.

Effectiveness and cost-effectiveness of oral nutritional supplements in frail older people who are malnourished or at risk of malnutrition: a systematic review and meta-analysis.

BACKGROUND: Current management of malnutrition can include prescribed oral nutritional supplements (ONS); however, there is uncertainty whether these supplements are effective in people who are older (≥65 years) and frail. We assessed the effectiveness, cost-effectiveness, and adherence and acceptability of ONS in frail older people who are malnourished or at risk of malnutrition. METHODS: In this systematic review and meta-analysis, five bibliographic databases (MEDLINE, EMBASE, Cochrane Library, Scopus, and CINAHL) and grey literature sources were searched from inception to Sept 13, 2021, to identify studies assessing the effectiveness and cost-effectiveness of ONS (with or without other dietary interventions) in frail older people who are malnourished or at risk of malnutrition. Multiple reviewers independently did study screening, data extraction, and risk of bias assessment. Quality was assessed using version 1.0 of the Cochrane risk of bias tool for randomised controlled trials (RCTs), and the BMJ Drummond checklist was used to assess the quality of the included cost-effectiveness study. A meta-analysis was done for the effectiveness review; for the other reviews, a narrative synthesis approach was used. This systematic review and meta-analysis was registered on PROSPERO, CRD42020170906. FINDINGS: Of 8492 records retrieved and screened, we included 11 RCTs involving 822 participants, six of which were fully or partly funded by industry. For the majority of the outcomes for which meta-analyses were possible (11/12), Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) assessments suggested that the evidence was of very low certainty. Results suggested that ONS might have a slightly positive effect on energy (kcal) intake (standardised mean difference 1·02 [95% CI 0·15 to 1·88]; I2=87%; four studies), protein intake (standardised mean difference 1·67 [-0·03 to 3·37; I2=97%; four studies), and mobility (mean difference 0·03 [0·02 to 0·04]; I2=0%; four studies), compared with standard care. Narrative syntheses suggested that the effect of ONS on quality of life, compared with standard care, was mixed. In the identified studies, there was very little information related to active components, determinants, or acceptability of interventions. One economic evaluation, done in a care home setting, showed that ONS could be cost-effective. INTERPRETATION: We found little evidence of ONS reducing malnutrition or its associated adverse outcomes in older people who are frail. High-quality, non-industry-funded, adequately powered studies reporting on short-term and long-term health outcomes, determinants, and participant characteristics are needed.

Socioeconomic Inequalities and Vaccine Uptake: An Umbrella Review Protocol.

The effectiveness of immunization is widely accepted: it can successfully improve health outcomes by reducing the morbidity and mortality associated with vaccine-preventable diseases. In the era of pandemics, there is a pressing need to identify and understand the factors associated with vaccine uptake amongst different socioeconomic groups. The knowledge generated from research in this area can be used to inform effective interventions aimed at increasing uptake. This umbrella systematic review aims to determine whether there is an association between socioeconomic inequalities and rate of vaccine uptake globally. Specifically, the study aims to determine whether an individual's socioeconomic status, level of education, occupation, (un)-employment, or place of residence affects the uptake rate of routine vaccines. The following databases will be searched from 2011 to the present day: Medline (Ovid), Embase (Ovid), CINAHL (EBSCO), Cochrane CENTRAL, Science Citation Index (Web of Science), DARE, SCOPUS (Elsevier), and ASSIA (ProQuest). Systematic reviews will be either included or excluded based on a priori established eligibility criteria. The relevant data will then be extracted, quality appraised, and narratively synthesised. The synthesis will be guided by the theoretical framework developed for this review. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Equity extension (PRISMA-E) guidance will be followed. This protocol has been registered on PROSPERO, ID: CRD42022334223.

Rapid priority setting exercise on faecal incontinence for Cochrane Incontinence.

OBJECTIVE: This rapid priority setting exercise aimed to identify, expand, prioritise and explore stakeholder (patients, carers and healthcare practitioners) topic uncertainties on faecal incontinence (FI). DESIGN: An evidence gap map (EGM) was produced to give a visual overview of emerging trial evidence; existing systematic review-level evidence and FI stakeholder topic uncertainties derived from a survey. This EGM was used in a knowledge exchange workshop that promoted group discussions leading to the prioritisation and exploration of FI stakeholder identified topic uncertainties. RESULTS: Overall, a mismatch between the existing and emerging evidence and key FI stakeholder topic uncertainties was found. The prioritised topic uncertainties identified in the workshop were as follows: psychological support; lifestyle interventions; long-term effects of living with FI; education; constipation and the cultural impact of FI. When these six prioritised topic uncertainties were explored in more depth, the following themes were identified: education; impact and burden of living with FI; psychological support; healthcare service improvements and inconsistencies; the stigma of FI; treatments and management; culturally appropriate management and technology and its accessibility. CONCLUSIONS: Topic uncertainties identified were broad and wide ranging even after prioritisation. More research is required to unpick the themes emerging from the in-depth discussion and explore these further to achieve a consensus on deliverable research questions.

Perceptual Disorders After Stroke: A Scoping Review of Interventions.

Perceptual disorders relating to hearing, smell, somatosensation, taste, touch, and vision commonly impair stroke survivors' ability to interpret sensory information, impacting on their ability to interact with the world. We aimed to identify and summarize the existing evidence for perceptual disorder interventions poststroke and identify evidence gaps. We searched 13 electronic databases including MEDLINE and Embase and Grey literature and performed citation tracking. Two authors independently applied a priori-defined selection criteria; studies involving stroke survivors with perceptual impairments and interventions addressing those impairments were included. We extracted data on study design, population, perceptual disorders, interventions, and outcomes. Data were tabulated and synthesized narratively. Stroke survivors, carers, and clinicians were involved in agreeing definitions and organizing and interpreting data. From 91 869 records, 80 studies were identified (888 adults and 5 children); participant numbers were small (median, 3.5; range, 1-80), with a broad range of stroke types and time points. Primarily focused on vision (34/80, 42.5%) and somatosensation (28/80; 35.0%), included studies were often case reports (36/80; 45.0%) or randomized controlled trials (22/80; 27.5%). Rehabilitation approaches (78/93; 83.9%), primarily aimed to restore function, and were delivered by clinicians (30/78; 38.5%) or technology (28/78; 35.9%; including robotic interventions for somatosensory disorders). Pharmacological (6/93; 6.5%) and noninvasive brain stimulation (7/93; 7.5%) approaches were also evident. Intervention delivery was poorly reported, but most were delivered in hospital settings (56/93; 60.2%). Study outcomes failed to assess the transfer of training to daily life. Interventions for stroke-related perceptual disorders are underresearched, particularly for pediatric populations. Evidence gaps include interventions for disorders of hearing, taste, touch, and smell perception. Future studies must involve key stakeholders and report this fully. Optimization of intervention design, evaluation, and reporting is required, to support the development of effective, acceptable, and implementable interventions.
