Our data point to cases where GPs exercised extensive influence over the strategic direction of the CCG as a whole and significant influence within specific service areas cheap levlen 0.15 mg line birth control quasense. In some of the cases this was because influential clinical figures took up roles as chairpersons or accountable officers and steered the CCG in a particular strategic direction discount 0.15mg levlen birth control reviews. The case studies which focused on reform of primary care, for example, illustrated how leading clinician managers occupying hybrid roles pursued the kinds of changes which reflected the visions set out in Liberating the NHS3 and those wanted by NHSE. The puzzle is why there were not more cases of this kind. The answer stems not only from the expected difficulties in carrying along the GP membership but, additionally, from the complex interplay of diverse institutions each with their power basis and each part of a wider web of services underpinned by payment mechanisms, which were found to be difficult to unravel. The scope for service redesign using the mechanism of these local commissioning groups was thus checked by numerous sources of inertia. Agents rooted in institutions can be expected to conform to the rules of those institutions; yet, as individual actors, they also have scope for the exercise of agency.

DISCUSSION the various institutions (organisational and professional), as indicated by Battilana,67 and also by the orientations and values of the individual actors. Regarding the influence of CCGs as institutions in a competitive institutional landscape, the picture is again mixed. We found examples where CCGs were marginal, peripheral players. The benefits being sought from clinical leadership The third question asked about the range of benefits being targeted through different kinds of clinical engagement and leadership. The most straightforward answer to this is that there was very evident commonality in the declared objectives of the would-be service redesigners. Integration of service was the big theme and care closer to home and away from secondary care was another. The findings suggest that the creation of CCGs did, to an extent, enable and prompt increased, and more potent, clinical leadership. As shown in the main body of the findings in this report, there were numerous examples of clinicians – along with managers – engaging seriously with service redesign and making a real difference to practice and to outcomes. However, this proved to be very irregular and uneven. Nor, after > 3 years of operation, did clinical leadership using the CCG platform, nor indeed CCGs themselves, live up, overall, to the level of expectation generated around the time of their inception. Part of the reason for this contingent and conditional performance was the degree of extraordinary turmoil in the wider context. This piece of institutional work had to compete with other, newer, initiatives. The research evidence, drawn from both the surveys and the case studies, revealed a number of weaknesses in the concept of GP-led commissioning groups. Insufficient numbers of GPs were willing to step forward to take up commissioning roles. In addition, with regard to those GPs in such roles, there was concern about the amount and quality of training and development. During the course of the study it was evident that GPs were showing more enthusiasm for leadership of the new provider bodies, such as the federations and the extended care delivery bodies. Hence, our work shows that clinical leadership seeks out spaces of influence almost regardless of the particular institutional arrangements.
