Concerns for the community services; between initiatives coming from highly future viability of some bringing operational emerging from GP committed and services are not fully clinical leadership into practice grouping and ambitious strategic addressed implementation of the larger-scale STPs leaders ACO Such benefits provide the core of a set of values that clinicians in both commissioning and providing roles have used to spread awareness of and commitment to new models of service provision. When this happens, it is also more likely to be influential within the operational delivery arenas. More generally, a convincing moral ethos can itself serve as a mechanism for binding together the inter-related leadership work that needs to take place within each of the three arenas we have identified. A second key feature of effective leadership for service innovation was a recognition, by those involved, that there are likely to be successive rounds of defining the nature of the new services and the skills involved. This defining work often involves rethinking the interfaces between previously overdefined and separate services that have become established under a contract-driven and somewhat adversarial model of commissioning. It also requires an interplay over time between the arenas of operational commissioning and operational delivery, as the requirements and performance potential of new service models become clearer. This sort of progressive defining and refining of service models, with clinical input on both the commissioning and provider side, is more likely to occur effectively under pilot arrangements, where competitive, market-driven aspects of commissioning are put in abeyance for a period or where system-driven co-production is emphasised (as in case F). More generally, our cases suggest that achieving effective clinical input requires commissioners to find ways of providing reassurance that they understand 80 NIHR Journals Library www. Issues of continued viability of particular provider organisations may need to be faced, but this is more likely to be done effectively if commissioners join providers in thinking through what a viable future might look like for them. A closely related factor that supported the development of clinical leadership across the three arenas was the presence of established formal and/or informal clinical networks. Innovation in primary care in case C built on established relationships between many practices and active locality structures. Innovation in the alliances in case A1 built on established relations between acute providers. Even in the less developed cases, such as case E1, achievements have built on existing relationships. Finally, Table 8 suggests a number of reasons why achieving coherence in clinical leadership across the three arenas may be difficult. Elaborate and far-reaching service redesigns over a wide geography can preoccupy clinical leaders when creating plans in strategic and operational commissioning arenas (points 1 and 2 in Figure 24). This sometimes detracts from the development of operational detail. It may also deflect effort away from building normative networks among front-line provider staff (cases E1 and F). Additionally, committed normative networks may emerge within providers, particularly among GPs who have been inspired by the aspirations of CCGs, but perhaps found that the realities of opportunities for influence have not lived up to their expectations. Such situations can lead to confusion and something of a vacuum at the operational commissioning level (point 2, see Figure 24), as delivery leaders recruit different NHS strategic initiatives to serve their purposes (case D). Notably, in case D, innovations in primary care were driven not by GPs as commissioners using the CCG as the lever, but rather by GPs as providers using GP federations as the vehicle for change. There were service innovations built around telephone triage, new workforce designs, self-care, targeted work with the frail elderly using specialist teams of GPs with special interest, pharmacists and specialist nurses. Some of the major clinical innovators involved in these initiatives were of the view that the CCGs were simply not delivering and the service and the patient simply could not wait for them. Thus, they said, the provider side needed to get on with the redesign and present it to the commissioners as a new offer. Although these initiatives were undoubtedly examples of clinically led service redesign, they were often stymied by the lack of a receptive and sufficiently resourced operational commissioning forum to consider them. Conclusions This chapter has analysed the role of clinical leadership in our eight cases in terms of three arenas, concerned with strategic commissioning, operational commissioning and operational service delivery. We have also made a distinction between the leadership work of instigating service redesign and that of implementing new models or concepts of service delivery.

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.
