There were service innovations built around telephone triage antibiotics lower blood sugar discount minocin express, new workforce designs antibiotic for pneumonia purchase minocin 50 mg without prescription, self-care antibiotic 7 days to die buy minocin 50 mg with visa, 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. In addition, we examined the range of ways that these activities can take place across the three arenas. A number of key points are worth bringing out by way of conclusion to our comparison of the eight cases. First, the leadership work of crafting operational detail is bound up with the operational delivery arena – without leadership work within this arena, operational solidity is unlikely to emerge. However, this institutional work of defining operational detail requires interchange with the operational commissioning arena, so that the staff and other resources or delivery are appropriate and also so that there can be iterative refinement of the overall concept and its ethos.

CROSS-CASE FINDINGS AND COMPARISONS Second, and perhaps more surprising, the leadership work of envisaging and articulating new service concepts can begin in any of the three arenas and often involves individuals who can move adroitly between them. We saw new service concepts being taken up to the strategic arena by clinicians who were also engaged in committed work in operational arenas, as well as cases where clinicians working mainly in strategic arenas formulated big ideas and found formal and informal ways of shaping powerfully the activities of colleagues in the other two kinds of arena. Above all, our analysis brings out the key role played by operational commissioning arenas for steering service innovation. Arenas such as programme boards appear to offer a forum where clinical leaders in CCG commissioning roles and in provider roles come together to integrate the institutional work of creating new models of service delivery. In order to do this, they can be seen as bringing clinical expertise and experience to bear in reconciling a number of perspectives which are potentially in conflict with one another. These include: l thinking differently about what established clinical professions do, in the context of services designed to address the needs of members of the public in a holistic way; tackling identified public health challenges rather than providing a service as defined by established clinical specialisms l developing new or modified professional identities and skills sets; clinical leaders in commissioning and provider roles became engaged in practical debate about the skills and sense of priorities of particular clinical roles l preserving and enhancing the expertise base of established clinical workforces; in some of our cases, provider clinical leaders took up a key role of working out how the expertise they represented could continue to be useful and relevant in a new service delivery model l identifying where national-level funding schemes offer opportunities or incentives for investments in new models of service; in some cases, the work of making sense of, and capitalising fully on, a plethora of national initiatives and sources of funding demanded a great deal of attention l preserving the income streams of established clinical provider organisations; in a number of cases both commissioners and providers found themselves dealing with complexity around whether or not to continue to support an established provider or advocate it be replaced by something different that might serve public health needs better. Grappling with these tensions involves much more than mediating between a managerial and a clinical perspective, which is one established notion of the work of clinical leadership. Our analysis of the work of programme boards suggests that clinicians and non-clinicians on such boards find themselves mediating between a variety of different managerial perspectives (e. One of the key lessons from our cases is the function of programme boards in providing a kind of adaptive leadership forum where complex dilemmas can be tackled through a process of dialogue, guided by an ethos of commitment to public health. Solutions to such dilemmas need to be discovered rather than imposed. This role of programme boards is particularly significant given the fact that, as we will see in the next chapter, these kinds of arenas do not exist in some health-care systems abroad. Although the original conception of CCGs emphasised the importance of their governing bodies as the place where the clinical voice would direct commissioning strategy, our cases demonstrate that this depends on carefully constructed operational commissioning forums, such as programme boards. In order to achieve this, we saw commissioners in these operational commissioning arenas finding ways to set aside models of market-based commissioning and instead seeking collaboration with providers to establish pilot arrangements for new models of care. These attempts frequently seemed to rely on using non-recurrent funding. One constant leadership task addressed within strategic commissioning areas is the authorisation and vesting of resources in the other two arenas. In some cases, the work of making sense of, and capitalising fully on, a plethora of national initiatives and sources of funding demanded a great deal of attention. The findings make clear that the integration of clinical leadership across the three arenas can be an uneven and lengthy process.
