In a minority of practices cheap 60 ml rogaine 2 amex prostate cancer and back pain, the PRISM lead GP changed between the three data collection points, because they retired or moved practice. We were unable to gather the views of community health staff after the tool was implemented, as most staff declined to attend a follow-up focus group because their roles had changed. Only one health services manager agreed to be interviewed at the end of the study. General practitioners taking part in the PRISMATIC trial volunteered for the study. In interviews, several identified themselves as interested in, or supportive of, research and wanted to contribute to knowledge generation by participating. They were therefore likely to be atypical of many GPs and their response to PRISM may not be that of other members of their profession. A summary of service user involvement can be found in Table 42.

SERVICE USER INVOLVEMENT TABLE 42 Summary of service user involvement in the PRISMATIC trial (continued) Type of involvement activity Role Process Comments Writing events To contribute service user Six meetings held (2012–15) Workshop sessions held at two perspective to all meetings to consider potential study discussions about Two service users were invited to outputs for service user audience communications and each meeting: at least one dissemination attended each meeting Discussions held about how to describe the PRISMATIC trial service user involvement in final report Service users contributed to all discussions as equal team members and agreed publications plan Publicity and Service users contributed to Service users reviewed and One service user contributed to dissemination publicity and dissemination contributed to seven PRISMATIC edition 6, writing about her materials about PRISMATIC newsletters, aimed at participating experience of being involved in GP practices and health services research managers One service user contributed to edition 7, explaining how risk prediction tools can help patients, especially those with early-stage chronic illness who can expect their condition to deteriorate Two newsletters contained articles by GP champions linked to the research team The SUCCESS group members advised on, and reviewed, the patient information pages of the PRISMATIC trial website Service users involved in Service users suggested production publicising PRISMATIC to patients and distribution of a poster about the PRISMATIC trial, for display in GP practices, to inform patients about the study One service user and one GP champion were interviewed by a TV crew about the study. The package was screened on the BBC Wales evening news Service users were co-authors on Service users co-authored conference all study outputs presentations Service users co-authored journal publication reporting baseline qualitative findings (Porter et al. As people changed, five individuals were involved over 5 years. All were diagnosed with chronic conditions and some also cared for family members. One of these individuals was actively involved throughout the whole period of the PRISMATIC trial. Poor health meant three other individuals had to give up their role. To reduce the burden on individuals, we recruited a reserve service user so there were potentially three to attend meetings and less need for anyone with family responsibilities or feeling unwell. Despite receiving briefings and project information, the reserve person reported that it was difficult to retain continuity when not regularly involved and there were long periods between meetings. When his health limited his ability to drive, the study team agreed not to recruit another person and resumed working with two service users. Halfway through the trial (December 2013), we held a meeting for service users and core research staff (BAE, MRK and HH) to review their experience and identify ways to enable them to sustain and increase their involvement. Study meetings At least one, often two, service users attended almost all RMG meetings (23/24). We recruited two different service users to the TSC; they attended three of five meetings. We also involved service users in task-related meetings such as writing days, meetings to undertake qualitative analysis and research development groups discussing further research linked to the topic of risk prediction. Research activities Throughout the period of the PRISMATIC trial, service users were involved in a range of research activities including: l RMG meetings – all aspects in an equal role with other RMG members l reviewing research information ¢ format of patient questionnaires ¢ patient letters and information sheets ¢ interview schedules ¢ abstracts and posters presented at conferences l qualitative data analysis l commenting on strategies to increase questionnaire response rates (prize draw) l deciding to have a patient page on the PRISMATIC trial website (RMG decision) l developing and reviewing the patient page of the PRISMATIC trial website (at SUCCESS group meetings) l commenting on consent issues relating to the use of anonymised data l publicity (British Broadcasting Corporation, newsletters); focus of British Broadcasting Corporation publicity was on one of the service users l TSC – two members l developing and piloting service user terms of reference (at SUCCESS group meetings and RMG) l informal dissemination about the PRISMATIC trial to patient networks l co-applicant on further research bids, including a systematic review of risk prediction models and developing an intervention to communicate risk scores with patients.

SERVICE USER INVOLVEMENT Reflections from one service user member of the PRISMATIC study I considered the PRISMATIC research to be advantageous to service users and I was pleased to be part of its development. I was able to pose questions and ask for explanations as part of the PRISMATIC team but felt there were some aspects of the research which could have taken a wider view. As a service user with chronic conditions I am aware of the problems with access to health services especially primary services, for example, GP surgeries. The research did not address the initial presentation at a GP surgery.
The search of available evidence did not identify any existing data showing a clear link between intervention-induced changes in PWV and final health outcomes in ESRD purchase 60 ml rogaine 2 with amex man health 99, but a large European observational study was identified. It highlighted the importance of simultaneously considering abdominal aortic calcification (AAC) when assessing the prognostic value of PWV. Based on a multivariate Cox regression, both variables were found to be significant predictors of mortality and non-fatal CV events, but the effect of PWV was ameliorated at higher levels of aortic calcification (incorporated as tertiles), as a result of a significant negative interaction. The relevant HRs from the published Cox regression are provided in Table 9. Based on these estimates, and assuming that the UK dialysis cohort is similarly distributed across aortic calcification tertiles, we estimated an average effect on all-cause mortality and non-fatal CV events of a unit change in PWV, accounting for the interaction. We then explored the impact of scaling this effect to the magnitude of the pooled mean reduction in PWV (1. We also explored the impact of applying it to the all-cause mortality rate in the model. These analyses should be treated with caution, as they rely on cross-sectional associative evidence from an observational study to inform possible effects of bioimpedance monitoring. It should be further noted that the pooled estimate for the effect of bioimpedance monitoring on PWV is non-significant and based on results from only two trials, showing inconsistent results (see Figure 7). However, the point estimate is applied in the base-case model and the uncertainty surrounding it is 40 NIHR Journals Library www. Furthermore, the negative interaction between increasing AAC tertiles and the effect of baseline PWV on mortality and CV event-related hospitalisation, suggests that the relative effect of reductions in PWV may be greater in lower-risk groups (with lower AAC scores). On the other hand, evidence for an interaction in the prognostic value of baseline measures of these two variables does not necessarily mean that the AAC score would modify the effect of an intervention-induced reduction in PWV. Therefore, this model could potentially over- or underestimate the likely effects of the estimated reduction in PWV on final health outcomes. Better evidence on the effects of intervention-induced reductions in PWV are required to inform this issue. As an alternative approach to indirectly estimate possible effects of bioimpedance-guided fluid management on mortality and CV event-related hospitalisation, we considered linking the estimated pooled reduction in SBP (2. Assuming a log-linear relationship between SBP reduction and the relative risk of events, these effects can be rescaled to the mean reduction in SBP across included BCM trials (2. These effects are substantially larger than the estimated effects using PWV above, and suggest a potentially larger effect on CV events than on all-cause mortality. However, it is uncertain if effects on SBP induced by blood pressure medication can be generalised to potential reductions in SBP induced by the management of fluid status, that is, some blood pressure medications are thought to have effects on CV events that are independent of their blood pressure-lowering effects. Nevertheless, the effect of bioimpedance-guided fluid management on SBP (bordering on significance), suggests a possible beneficial effect on both CV events and mortality. Therefore, we explored the impact of applying larger and differential relative effects on these outcomes in further scenario analyses.

ASSESSMENT OF COST-EFFECTIVENESS Finally, we also explored the impact of using associations between overhydration and all-cause mortality and hospitalisation rates to drive effects in the model. This analysis assumed that for everyone who is moved from the overhydrated (relative fluid overload > 15%) to the normally hydrated state, the increased risks associated with overhydration are completely reversed. This was an optimistic assumption, as, again, cross-sectional associations between baseline measures and final outcomes were used to drive the effects of bioimpedance-guided fluid management in the model. The increased risk associated with baseline overhydration may not be fully reversible for those that can be returned to normal hydration status (≤ 15%). A further problem with this approach is the lack of reporting in the RCTs on the effect of bioimpedance- guided fluid management on the proportion of patients with pre-dialysis ROH of > 15% at baseline and follow-up. Yet, the study did demonstrate a significant effect on PWV and mortality, leading the authors to speculate that the mechanism for effect may be as much a result of the avoidance of chronic underhydration as overhydration. We used these data to approximate percentage reductions in ROH of > 15% (absolute overhydration of > 2. This yielded plausible percentage reductions in ROH of > 15% from 28% to 38% with bioimpedance-guided management relative to control. These were applied in model scenarios utilising the change in ROH status to drive effects on all-cause mortality and all-cause hospitalisation. Further hypothesised benefits of bioimpedance-guided fluid management that were not incorporated in the main analyses included changes in quality of life (independent of effects on hospitalisation and CV events), maintenance of residual renal function and effects on dialysis requirements (number and duration of sessions).
