    Economic evidence for the prevention and treatment of atopic eczema: a protocol for a systematic review

    Get PDF
    Background: Eczema, synonymous with atopic eczema or atopic dermatitis, is a chronic skin disease that has a similar impact on health-related quality of life as other chronic diseases. The proposed research aims to provide a comprehensive systematic assessment of the economic evidence base available to inform economic modelling and decision making on interventions to prevent and treat eczema at any stage of the life course. Whilst the Global Resource of Eczema Trials (GREAT) database collects together the effectiveness evidence for eczema there is currently no such systematic resource on the economics of eczema. It is important to gain an overview of the current state of the art of economic methods in the field of eczema in order to strengthen the economic evidence base further. Methods/design: The proposed study is a systematic review of the economic evidence surrounding interventions for the prevention and treatment of eczema. Relevant search terms will be used to search MEDLINE, EMBASE, Database of Abstracts of Reviews of Effects, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, NHS Economic Evaluation Database, Health Technology Assessment, Cumulative Index to Nursing and Allied Health Literature, Econ Lit, Scopus, Cost-Effectiveness Analysis Registry and Web of Science in order to identify relevant evidence. To be eligible for inclusion studies will be primary empirical studies evaluating the cost, utility or full economic evaluation of interventions for preventing or treating eczema. Two reviewers will independently assess studies for eligibility and perform data abstraction. Evidence tables will be produced presenting details of study characteristics, costing methods, outcome methods and quality assessment. The methodological quality of studies will be assessed using accepted checklists. Discussion: The systematic review is being undertaken to identify the type of economic evidence available, summarise the results of the available economic evidence and critically appraise the quality of economic evidence currently available to inform future economic modelling and resource allocation decisions about interventions to prevent or treat eczema. We aim to use the review to offer guidance about how to gather economic evidence in studies of eczema and/or what further research is necessary in order to inform this

    Why prospective registration of systematic reviews makes sense

    Prospective registration of systematic reviews promotes transparency, helps reduce potential for bias and serves to avoid unintended duplication of reviews. Registration offers advantages to many stakeholders in return for modest additional effort from the researchers registering their reviews

    The natural course of pain and disability following primary lumbar discectomy: protocol for a systematic review and meta-analysis

    Get PDF
    Introduction Knowledge about the natural clinical course is needed to improve understanding of recovery postsurgery as outcome is poor for some patients. Knowledge of the natural clinical course of symptoms and disability will inform optimal timing and the nature of rehabilitation intervention. The objective of this study is to provide first evidence synthesis investigating the natural clinical course of disability and pain in patients aged >16 years post primary lumbar discectomy. Methods and analysis A systematic review and data synthesis will be conducted. Prospective cohorts that include a well-defined inception cohort (point of surgery) of adult participants who have undergone primary lumbar discectomy/microdiscectomy will be included. Outcomes will include measurements reported on 1 or more outcomes of disability and pain, with a baseline presurgery measurement. Following development of the search strategy, 2 reviewers will independently search information sources, assess identified studies for inclusion, extract data and assess risk of bias. A third reviewer will mediate on any disagreement at each stage. The search will employ sensitive topic-based strategies designed for each database from inception to 31 January 2016. There will be no language or geographical restrictions. Risk of bias will be assessed using a modified QUality In Prognostic Studies (QUIPS) tool . Data will be extracted for time points where follow-up was at least 80%. Means and 95% CIs will be plotted over time for pain and disability. All results will be reported in the context of study quality. Ethics and dissemination This review will provide the first rigorous summary of the course of pain and disability across all published prospective cohorts. The findings will inform our understanding of when to offer and how to optimise rehabilitation following surgery. Results will be published in an open access journal. The study raises no ethical issues

    Mindfulness-based stress reduction as supportive therapy in cancer care: systematic review

    Get PDF
    Aim: This paper reports a systematic review and critical appraisal of the evidence on the effectiveness of Mindfulness-Based Stress Reduction for cancer supportive care. Background: The experience of cancer can have a negative impact on both psychological and physical health and on quality of life. Mindfulness-Based Stress Reduction is a therapy package that has been used with patients with a variety of conditions. In order to draw conclusions on its effectiveness for cancer patients, the evidence requires systematic assessment. Methods: A comprehensive search of major biomedical and specialist complementary medicine databases was conducted. Additionally, efforts were made to identify unpublished and ongoing research. Relevant research was categorized by study type and appraised according to study design. Clinical commentaries were obtained for each study and included in the review. Results: Three randomized controlled clinical trials and seven uncontrolled clinical trials were found. A lack of relevant qualitative research studies was identified. Studies report positive results, including improvements in mood, sleep quality and reductions in stress. A dose-response effect has been observed between practice of Mindfulness-Based Stress Reduction and improved outcome. A number of methodological limitations were identified. Modifications to the traditional Mindfulness-Based Stress Reduction programme make comparison between studies difficult and a lack of controlled studies precludes any firm conclusion on efficacy. Conclusion: Mindfulness-Based Stress Reduction has potential as a clinically valuable self-administered intervention for cancer patients. Further research into its efficacy, feasibility and safety for cancer patients in the nursing context is recommended

    The state of the art in non-pharmacological interventions for developmental stuttering. Part 1: a systematic review of effectiveness

    Get PDF
    Background The growing range of available treatment options for people who stutter presents a challenge for clinicians, service managers and commissioners, who need to have access to the best available treatment evidence to guide them in providing the most appropriate interventions. While a number of reviews of interventions for specific populations or a specific type of intervention have been carried out, a broad-based systematic review across all forms of intervention for adults and children was needed to provide evidence to underpin future guidelines, inform the implementation of effective treatments and identify future research priorities. Aims To identify and synthesize the published research evidence on the clinical effectiveness of the broad range of non-pharmacological interventions for the management of developmental stuttering. Methods & Procedures A systematic review of the literature reporting interventions for developmental stuttering was carried out between August 2013 and April 2014. Searches were not limited by language or location, but were restricted by date to studies published from 1990 onwards. Methods for the identification of relevant studies included electronic database searching, reference list checking, citation searching and hand searching of key journals. Appraisal of study quality was performed using a tool based on established criteria for considering risk of bias. Due to heterogeneity in intervention content and outcomes, a narrative synthesis was completed. Main Contribution The review included all available types of intervention and found that most may be of benefit to at least some people who stutter. There was evidence, however, of considerable individual variation in response to these interventions. The review indicated that effects could be maintained following all types of interventions (although this was weakest with regard to feedback and technology interventions). Conclusions This review highlights a need for greater consensus with regard to the key outcomes used to evaluate stuttering interventions, and also a need for enhanced understanding of the process whereby interventions effect change. Further analysis of the variation in effectiveness for different individuals or groups is needed in order to identify who may benefit most from which intervention

    Ophthalmic artery Doppler for prediction of pre‐eclampsia: systematic review and meta‐analysis

    Objective To determine the accuracy of ophthalmic artery Doppler in pregnancy for the prediction of pre‐eclampsia (PE). Methods MEDLINE, EMBASE, CINAHL and The Cochrane Library were searched for relevant citations without language restrictions. Two reviewers independently selected studies that evaluated the accuracy of ophthalmic artery Doppler to predict the development of PE and extracted data to construct 2 × 2 tables. Individual patient data were obtained from the authors if available. A bivariate random‐effects model was used for the quantitative synthesis of data. Logistic regression analysis was employed to generate receiver–operating characteristics (ROC) curves and obtain optimal cut‐offs for each investigated parameter, and a bivariate analysis was employed using predetermined cut‐offs to obtain sensitivity and specificity values and generate summary ROC curves. Results A total of 87 citations matched the search criteria of which three studies, involving 1119 pregnancies, were included in the analysis. All included studies had clear description of the index and reference tests, avoidance of verification bias and adequate follow‐up. Individual patient data were obtained for all three included studies. First diastolic peak velocity of ophthalmic artery Doppler at a cut‐off of 23.3 cm/s showed modest sensitivity (61.0%; 95% CI, 44.2–76.1%) and specificity (73.2%; 95% CI, 66.9–78.7%) for the prediction of early‐onset PE (area under the ROC curve (AUC), 0.68; 95% CI, 0.61–0.76). The first diastolic peak velocity had a much lower sensitivity (39.0%; 95% CI, 20.6–61.0%), a similar specificity (73.2%; 95% CI, 66.9–78.7%) and a lower AUC (0.58; CI, 0.52–0.65) for the prediction of late‐onset PE. The pulsatility index of the ophthalmic artery did not show a clinically useful sensitivity or specificity at any cut‐off for early‐ or late‐onset PE. Peak ratio above 0.65 showed a similar diagnostic accuracy to that of the first diastolic peak velocity with an AUC of 0.67 (95% CI, 0.58–0.77) for early‐onset PE and 0.57 (95% CI, 0.51–0.63) for late‐onset disease. Conclusions Ophthalmic artery Doppler is a simple, accurate and objective technique with a standalone predictive value for the development of early‐onset PE equivalent to that of uterine artery Doppler evaluation. The relationship between ophthalmic Doppler indices and PE cannot be a consequence of trophoblast invasion and may be related to maternal hemodynamic adaptation to pregnancy. The findings of this review justify efforts to elucidate the effectiveness and underlying mechanism whereby two seemingly unrelated maternal vessels can be used for the prediction of a disease considered a ‘placental disorder’

    BACKGROUND: A recent study by Page et al. (PLoS Med. 2016;13(5):e1002028) claimed that increasing numbers of reviews are being published and many are poorly-conducted and reported. The aim of the present study was to assess how well reporting standards of systematic reviews produced in a Health Technology Assessment (HTA) context compare with reporting in Cochrane and other 'non-Cochrane' systematic reviews from the same years (2004 and 2014), as reported by Page et al. (PLoS Med. 2016;13(5):e1002028). METHODS: All relevant UK HTA programme systematic reviews published in 2004 and 2014 were identified. After piloting of the form, two reviewers each extracted relevant data on conduct and reporting from these reviews. These data were compared with data for Cochrane and "non-Cochrane" systematic reviews, as published by Page et al. (PLoS Med. 2016;13(5):e1002028). All data were tabulated and summarized. RESULTS: There were 30 UK HTA programme systematic reviews and 300 other systematic reviews, including Cochrane reviews (n = 45). The percentage of HTA reviews with required elements of conduct and reporting was frequently very similar to Cochrane and much higher than all other systematic reviews, e.g. availability of protocols (90, 98 and 16% respectively); the specification of study design criteria (100, 100, 79%); the reporting of outcomes (100, 100, 78%), quality assessment (100, 100, 70%); the searching of trial registries for unpublished data (70, 62, 19%); reporting of reasons for excluding studies (91, 91 and 70%) and reporting of authors' conflicts of interests (100, 100, 87%). HTA reviews only compared less favourably with Cochrane and other reviews in assessments of publication bias. CONCLUSIONS: UK HTA systematic reviews are often produced within a specific policy-making context. This context has implications for timelines, tools and resources. However, UK HTA systematic reviews still tend to present standards of conduct and reporting equivalent to "gold standard" Cochrane reviews and superior to systematic reviews more generally

    The meaning of play for children and young people withphysical disabilities: A systematic thematic synthesis

    Get PDF
    Children and young people with physical disabilities are often reported to play less than their typically developing peers. Few studies explore the meaning of play from the child's perspective; this study carried out a thematic synthesis of the findings of qualitative studies about the meaning of play following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines. Methods: A search of CINAHL, AHMED, PsycINFO, MEDLINE, EMBASE, and ERIC was undertaken between September 2015 and March 2016. Qualitative studies exploring the meaning of play from the perspective of 0‐ to 18‐year‐olds with physical disabilities impacting function were included. Quality appraisal and thematic synthesis were undertaken in order to develop analytical themes. Results: Thirteen studies met the inclusion criteria in part addressing the meaning of play for children and young people with physical disabilities. Synthesis of the findings identified 5 analytical themes: Play can feel both positive and negative; play can draw attention towards or awayfrom my disability; play is a social interaction; I participate differently to my peers, and needing help feels normal. Conclusions: The themes highlight the potential for play experiences of individuals with physical disabilities being overlooked by parents and professionals; further research is needed to explore play experience from these individual's perspective
