Parents and professionals strongly identify participation as one of the overarching objectives of therapy interventions purchase mentat 60caps on line. The notion of participation as an appropriate and meaningful outcome indicator for therapy interventions was questioned buy 60caps mentat with visa, particularly evaluations of a specific procedure or technique. There was agreement that, when properly implemented into a study design, participation may be an appropriate indicator in studies evaluating the impact of wider models of care. Some of these outcomes may be better conceived as intermediate outcomes. Quality of life, physical and emotional well-being, resilience and self-management were identified as potentially relevant higher-level outcomes. Typically, there is not a strong culture of research within therapy services. However, within the professions there is growing engagement with and interest in research. A broad-ranging agenda of research priorities was identified. A number of methodological and study design issues were identified as barriers to evaluation research. Research priorities concerning particular techniques, procedures or items of equipment generated a long list of potential studies. These appeared to be located in personal preferences and clinical experience, and none emerged as receiving strong and consistent support. There was universal consensus that evaluative research needs to use mixed methods, and patient experience as well as outcomes should be captured. Health economics and implementation science were consistently identified as needing to be core components of evaluation studies. This was despite extensive and creative efforts being made within the constraints of time and resources arising from the fact this was a commissioned study being delivered within a fixed 9-month timeline. Additional work is required to consult with children and young people, and we would suggest that the findings from this study would provide a useful and effective starting point for discussion and consultation. In addition, the study did not incorporate a patient and public involvement element, and nor did its design include sufficient representation from school/education staff. Final comments This study was commissioned by NIHR to inform strategic decision-making in terms of its response to the findings of a JLA research prioritisation exercise for children with neurodisability. Four of the top 10 priorities emerging from this exercise concerned therapy interventions. Within NIHR, it was the HTA programme that initiated this scoping study. The findings from this piece of work suggest that a much broader approach to tackling the significant evidence gaps related to therapy interventions for children with neurodisability would be appropriate, embracing, for example, the HSDR, Efficacy and Mechanism Evaluation and Programme Grants for Applied Research programmes, as well as the Medical Research Council-NIHR Methodology Research Programme.

Our sincere thanks go to them for their interest and involvement. We would also like to express our thanks to the individuals within parent-led support and advocacy organisations who brought together relevant parents on our behalf and co-ordinated arrangements for, and hosted, focus groups. We would also like to acknowledge the efforts made by many of our professional interviewees to participate in this scoping study, protecting time and fully and thoughtfully engaging with the topics we wanted to explore. Some of these individuals also facilitated contacts with other research participants or organised focus groups with therapy practitioners. We are very grateful for this commitment and support to the project. Finally, we would like to thank Teresa Frank, who ably provided administrative support to the project.

However, these methods are not precise, and measurement devices based on bioimpedance technology are increasingly used in dialysis centres. Current evidence on the role of bioimpedance devices for fluid management in people with CKD receiving dialysis is limited. Objectives: To evaluate the clinical effectiveness and cost-effectiveness of multiple-frequency bioimpedance devices versus standard clinical assessment for fluid management in people with CKD receiving dialysis. Data sources: We searched major electronic databases [e. MEDLINE, MEDLINE In-Process & Other Non-Indexed Citations, EMBASE, Science Citation Index and Cochrane Central Register of Controlled Trials (CENTRAL)] conference abstracts and ongoing studies. Searches were undertaken between June and October 2016. Review methods: Evidence was considered from randomised controlled trials (RCTs) comparing fluid management by multiple-frequency bioimpedance devices and standard clinical assessment in people receiving dialysis, and non-randomised studies evaluating the use of the devices for fluid management in people receiving dialysis. One reviewer extracted data and assessed the risk of bias of included studies. Standard meta-analyses techniques were used to combine results from included studies. A Markov model was developed to assess the cost-effectiveness of the interventions. Results: Five RCTs (with 904 adult participants) and eight non-randomised studies (with 4915 adult participants) assessing the use of the Body Composition Monitor [(BCM) Fresenius Medical Care, Bad Homburg vor der Höhe, Germany] were included. Both absolute overhydration and relative overhydration were significantly lower in patients evaluated using BCM measurements than for those evaluated using standard clinical methods [weighted mean difference –0.

The economic evaluation showed that, when dialysis costs were included in the model, the probability of bioimpedance monitoring being cost-effective ranged from 13% to 26% at a willingness-to-pay threshold of £20,000 per quality-adjusted life-year gained. With dialysis costs excluded, the corresponding probabilities of cost-effectiveness ranged from 61% to 67%. Limitations: Lack of evidence on clinically relevant outcomes, children receiving dialysis, and any multifrequency bioimpedance devices, other than the BCM. Conclusions: BCM used in addition to clinical assessment may lower overhydration and potentially improve intermediate outcomes, such as SBP, but effects on mortality have not been demonstrated. If dialysis costs are not considered, the incremental cost-effectiveness ratio falls below £20,000, with modest effects on mortality and/or hospitalisation rates. The current findings are not generalisable to paediatric populations nor across other multifrequency bioimpedance devices. Future work: Services that routinely use the BCM should report clinically relevant intermediate and long-term outcomes before and after introduction of the device to extend the current evidence base.
