OBJECTIVE To determine the effectiveness of mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT) on psychological and physical outcomes for people with vascular disease. DESIGN Systematic review and meta-analysis of randomised controlled trials. DATA SOURCES AMED, CINAHL, EMBASE, British Nursing Index, Medline, Web of Science, PsycINFO, Cochrane Database of Systematic Reviews, Central, Social Sciences Citation Index, Social Policy and Practice, and HMIC from inception to January 2013. REVIEW METHODS Articles were screened for inclusion independently by two reviewers. Data extraction and quality appraisal were performed by one reviewer and checked by a second with discrepancies resolved by discussion with a third if necessary. Random-effects meta-analyses were performed. RESULTS Nine articles (from eight original randomised controlled trials) met eligibility criteria and were included in the final review. In total, 578 participants were enrolled across the trials, with participants presenting with prehypertension/hypertension (n=3 trials), type 1 or 2 diabetes (n=2), heart disease (n=2) and stroke (n=1). Meta-analyses, using standardised mean differences, showed evidence of reductions in stress (-0.36; 95% CI -0.67 to -0.09; p=0.01), depression (-0.35; 95% CI -0.53 to -0.16; p=0.003) and anxiety (-0.50; 95% CI -0.70 to -0.29; p<0.001). Effects on physical outcomes (blood pressure, albuminuria, stress hormones) were mixed. CONCLUSION Whilst populations with vascular disease appear to derive a range of psychological benefits from MBSR/MBCT intervention, the effects on physical parameters of disease are not yet established. More robust studies, with longer term follow-up, are required to ascertain full effectiveness of such intervention.

The need to improve the nutrition of the elderly living in long term care has long been recognised, but how this can best be achieved, and whether (and which) intervention is successful in reducing morbidity is less well understood. The aim of this systematic review was to determine the effectiveness of mealtime interventions for the elderly living in residential care. Mealtime interventions were considered as those that aimed to change/improve the mealtime routine, practice, experience or environment. Following comprehensive searches, review and appraisal, 37 articles were included. Inadequate reporting in over half of the articles limited data quality appraisal. Mealtime interventions were categorised into five types: changes to food service, food improvement, dining environment alteration, staff training and feeding assistance. Meta-analysis found inconsistent evidence of effects on body weight of changes to food service (0.5 kg; 95% CI: -1.1 to 2.2; p=0.51), food improvement interventions (0.4 kg; 95% CI: -0.8 to 1.7; p=0.50) or alterations to dining environment (1.5 kg; 95% CI: -0.7 to 2.8; p=0.23). Findings from observational studies within these intervention types were mixed, but generally positive. Observational studies also found positive effects on food/caloric intake across all intervention types, though meta-analyses of randomised studies showed little evidence of any effects on food/caloric intake in food improvement studies (-5 kcal; 95% CI: -36 to 26; p=0.74). There was some evidence of an effect on daily energy intakes within dining environment studies (181 kcal/day, 95% CI: -5 to 367, p=0.06). The need to improve the nutrition of the elderly living in residential long term care is well recognised. This review found some evidence that simple intervention around various aspects of mealtime practices and the mealtime environment can result in favourable nutritional outcomes. Further large scale pragmatic trials, however, are still required to establish full efficacy of such interventions.

OBJECTIVE Elderly residents with dementia commonly exhibit increased agitation at mealtimes. This interferes with eating and can be distressing for both the individual and fellow residents. This review examines the effectiveness of mealtime interventions aimed at improving behavioral symptoms in elderly people living with dementia in residential care. DESIGN Systematic review. DATA SOURCES Medline, PsycINFO, Embase, HMIC, AMED (OvidSP); CDSR, CENTRAL, DARE (Cochrane Library, Wiley); CINAHL (EBSCOhost); British Nursing Index (NHS Evidence); ASSIA (ProQuest); Social Science Citation Index (Web of Knowledge); EThOS (British Library); Social Care Online and OpenGrey from inception to November 2012. Forward and backward citation chases, hand searches of other review articles identified in the search, and key journals. TYPES OF STUDY All comparative studies were included. Articles were screened for inclusion independently by 2 reviewers. Data extraction and quality appraisal were performed by one reviewer and checked by a second with discrepancies resolved by discussion with a third if necessary. Data were not suitable for meta-analysis so narrative synthesis was carried out. RESULTS A total of 6118 articles were identified in the original search. Eleven articles were finally included. Mealtime interventions were categorized into 4 types: music, changes to food service, dining environment alteration, and group conversation. Study quality was poor, making it difficult to reach firm conclusions. Although all studies showed a trend in favor of the intervention, only 6 reported a statistically significant improvement in behavioral symptoms. Four studies suggest cumulative or lingering effects of music on agitated and aggressive behaviors. CONCLUSION There is some evidence to suggest that mealtime interventions improve behavioral symptoms in elderly people with dementia living in residential care, although weak study designs limit the generalizability of the findings. Well designed, controlled trials are needed to further understand the utility of mealtime interventions in this setting.

OBJECTIVE Depression is more common among individuals with chronic physical illness than in the general population. New treatments for severe and chronic inflammatory conditions which inhibit tumour necrosis factor alpha (TNF-α), a pro-inflammatory cytokine, may be able to shed some light on the role of inflammatory mediators in depression. This systematic review and meta-analysis of randomised controlled trials determined the effects of TNF-α inhibitor therapy on depression and anxiety in people with chronic physical illness. METHODS Seven databases were searched from inception to January 2014: AMED, Central, Cochrane Database of Systematic Reviews, CINAHL, Embase, MEDLINE, and PsycINFO. Articles were screened for inclusion independently by two reviewers. Data extraction and appraisal were conducted by one reviewer and checked by a second. Random-effects meta-analyses were performed. RESULTS Six randomised controlled trials (reported in seven articles) met eligibility criteria and were included in the final review. In total 2540 participants were enrolled across the trials, with participants presenting with rheumatoid arthritis (n=3 trials), psoriasis (n=2) or ankylosing spondylitis (n=1). Meta-analyses, using standardised mean differences, showed evidence of small reductions in depression (-0.24; 95% CI -0.33 to -0.14; p<0.001), and anxiety (-0.17; 95% CI -0.31 to -0.02; p=0.02). CONCLUSION TNF-α inhibitor therapy reduces depression in people with chronic disease though the effects are small. Whilst this is consistent with inflammation contributing to the development of depression, further studies investigating a more detailed timeline of changes in depression, inflammatory biomarkers and disease activity status are required.

ABSTRACT Attention Restoration Theory (ART) suggests the ability to concentrate may be restored by exposure to natural environments. Although widely cited, it is unclear as to the quantity of empirical evidence that supports this. A systematic review regarding the impact of exposure to natural environments on attention was conducted. Seven electronic databases were searched. Studies were included if (1) they were natural experiments, randomized investigations, or recorded “before and after” measurements; (2) compared natural and nonnatural/other settings; and (3) used objective measures of attention. Screening of articles for inclusion, data extraction, and quality appraisal were performed by one reviewer and checked by another. Where possible, random effects meta-analysis was used to pool effect sizes. Thirty-one studies were included. Meta-analyses provided some support for ART, with significant positive effects of exposure to natural environments for three measures (Digit Span Forward, Digit Span Backward, and Trail Making Test B). The remaining 10 meta-analyses did not show marked beneficial effects. Meta-analysis was limited by small numbers of investigations, small samples, heterogeneity in reporting of study quality indicators, and heterogeneity of outcomes. This review highlights the diversity of evidence around ART in terms of populations, study design, and outcomes. There is uncertainty regarding which aspects of attention may be affected by exposure to natural environments.

Childhood psychiatric disorders are associated with a wide range of adverse outcomes including poor academic attainment. For some children these difficulties are recognised through school Special Educational Need procedures (SEN) but many others may remain unidentified and/or unsupported. In Britain, government data suggests disproportionate representation of children with a SEN among children permanently excluded from school. This review asks whether school-aged children with impairing psychopathology were more likely to be excluded from school than those without. Databases covering education, social sciences, psychology and medicine were searched, experts were contacted and bibliographies of key papers were hand-searched. Studies were included if the population covered school-aged children, and if validated diagnostic measures had been used to assess psychopathology. Children with impairing psychopathology had greater odds of exclusion compared to the rest of the school-age population: odds ratios range from 1.13 (95% CI: 0.55–2.33) to 45.6 (95% CI: 3.8–21.3). These findings however need to be considered in light of the paucity of the literature and methodological weaknesses discussed.

BackgroundThe use of non-drug, non-health-service interventions has been proposed as a cost-effective alternative to help those with long-term conditions manage their illness and improve their health and well-being. Interventions typically involve accessing activities run by the third sector or community agencies and may also be described as non-medical referral, community referral or social prescribing. To be effective, patients need to be “transferred” from the primary care setting into the community and to maintain their participation in activities. However, it is not currently known how and why these approaches enable which people under what circumstances to reach community services that may benefit their health and well-being.MethodsDatabase searches and extensive searching of grey sources will be carried out in an attempt to find evidence associated with referral and retention in social prescribing. After initial scoping searches, two main phases of searching will be conducted: (a) will focus on the identification of programme theories to illustrate how approaches to social prescribing work for different people and in different contexts and (b) will consist of targeted searches to locate evidence to refine these candidate theories into configurations of the contexts in which populations and the main mechanisms outcomes are achieved. Inclusion criteria will initially be broad in order to develop a clear picture of the ways in which social prescriptions might operate but may iteratively become more focused in response to initially identified evidence, for example, in terms of the population group.An expert advisory group consisting of professionals working in a range of organisations involved in social prescribing will be convened to check the approaches in the review and provide real-life experience of social prescribing. Findings from the review will be disseminated to commissioners, published in a peer-reviewed journal and used to help refine an intervention model for an outdoor nature-based group intervention.DiscussionThis realist review will explore why mechanisms of social prescribing work, for what groups of people and their impact on enrolment, attendance and adherence to programmes. The use of realist approaches to detail the social prescribing process is novel and will offer insights into effective transfer of patients.Systematic review registrationPROSPERO CRD42016039491

Development and testing of a medline search filter for identifying patient and public involvement in health research

Morwenna Rogers; Alison Bethel; Kate Boddy

Abstract Background Research involving the public as partners often proves difficult to locate due to the variations in terms used to describe public involvement, and inability of medical databases to index this concept effectively. Objective To design a search filter to identify literature where patient and public involvement (PPI) was used in health research. Methods A reference standard of 172 PPI papers was formed. The references were divided into a development set and a test set. Search terms were identified from common words, phrases and synonyms in the development set. These terms were combined as a search strategy for medline via OvidSP, which was then tested for sensitivity against the test set. The resultant search filter was then assessed for sensitivity, specificity and precision using a previously published systematic review. Results The search filter was found to be highly sensitive 98.5% in initial testing. When tested against results generated by a ‘real‐life’ systematic review, the filter had a specificity of 81%. However, sensitivity dropped to 58%. Adjustments to the population group of terms increased the sensitivity to 73%. Conclusion The PPI filter designed for medline via OvidSP could aid information specialists and researchers trying to find literature specific to PPI.

Whole-system approaches to improving the health and wellbeing of healthcare workers: A systematic review

Sarah Brand; Jo Thompson-Coon; Lora E. Fleming; Lauren Carroll; Alison Bethel; Katrina Wyatt

Background Healthcare professionals throughout the developed world report higher levels of sickness absence, dissatisfaction, distress, and “burnout” at work than staff in other sectors. There is a growing call for the ‘triple aim’ of healthcare delivery (improving patient experience and outcomes and reducing costs; to include a fourth aim: improving healthcare staff experience of healthcare delivery. A systematic review commissioned by the United Kingdom’s (UK) Department of Health reviewed a large number of international healthy workplace interventions and recommended five whole-system changes to improve healthcare staff health and wellbeing: identification and response to local need, engagement of staff at all levels, and the involvement, visible leadership from, and up-skilling of, management and board-level staff. Objectives This systematic review aims to identify whole-system healthy workplace interventions in healthcare settings that incorporate (combinations of) these recommendations and determine whether they improve staff health and wellbeing. Methods A comprehensive and systematic search of medical, education, exercise science, and social science databases was undertaken. Studies were included if they reported the results of interventions that included all healthcare staff within a healthcare setting (e.g. whole hospital; whole unit, e.g. ward) in collective activities to improve physical or mental health or promote healthy behaviours. Results Eleven studies were identified which incorporated at least one of the whole-system recommendations. Interventions that incorporated recommendations to address local need and engage the whole workforce fell in to four broad types: 1) pre-determined (one-size-fits-all) and no choice of activities (two studies); or 2) pre-determined and some choice of activities (one study); 3) A wide choice of a range of activities and some adaptation to local needs (five studies); or, 3) a participatory approach to creating programmes responsive and adaptive to local staff needs that have extensive choice of activities to participate in (three studies). Only five of the interventions included substantial involvement and engagement of leadership and efforts aimed at up-skilling the leadership of staff to support staff health and wellbeing. Incorporation of more of the recommendations did not appear to be related to effectiveness. The heterogeneity of study designs, populations and outcomes excluded a meta-analysis. All studies were deemed by their authors to be at least partly effective. Two studies reported statistically significant improvement in objectively measured physical health (BMI) and eight in subjective mental health. Six studies reported statistically significant positive changes in subjectively assessed health behaviours. Conclusions This systematic review identified 11 studies which incorporate at least one of the Boorman recommendations and provides evidence that whole-system healthy workplace interventions can improve health and wellbeing and promote healthier behaviours in healthcare staff.

BackgroundThis paper provides guidance about how to plan, prepare, conduct, report, amend or update a systematic search. It aims to contribute to a new version of the Collaboration for Environmental Evidence (CEE) Guidelines for Systematic Reviews in Environmental Management, and the methods we describe are likely to be broadly applicable across a wider range of topics. In evidence synthesis, searches are expected to be repeatable, fit for purpose, with minimum biases, and to collate a maximum number of relevant articles. Failing to include relevant information in an evidence synthesis may lead to inaccurate or skewed conclusions and/or changes in conclusions as soon as the omitted information is added.MethodThe paper takes into account similar documents produced by the Cochrane Collaboration and the Campbell Collaboration, including necessary adjustments for environmental policy and management, and the current version of the CEE Guidelines (version 4.2, 2013). Where possible this guidance is based on evidence from research, and in its absence on expert opinion and experience.ResultsHere we aim to provide guidance on the optimal search structure as the basis on which any evidence synthesis should be built.ConclusionIt is aimed at all those who intend to conduct systematic evidence synthesis, including reviews and Ph.D. thesis.
