The core prevailing logics were spelled out time and time again – in CCG strategy documents; in STPs and the workshops organised to prepare these plans; in NHSE statements and documents; and in our many interviews with actors at all levels and parts of the health service discount fluoxetine 10mg fast delivery define women's health issues. These competing logics coexisted as layers of statute and reform were laid on top of each other purchase 10 mg fluoxetine overnight delivery women's health clinic gawler, pulling system actors in different directions. It was within this context that clinical leadership was being exercised or neglected.

It has been noted that embedded actors often cleave to an institutional form because it has a taken-for-granted status that engenders a deep-seated belief in the necessity of the extant system. A database of 3100 individual members of governing boards was constructed by tracking board papers and CCG websites. The questionnaires (see Appendix 3) were posted to this total population using their individual names and addresses. One postal reminder was then sent to those who had not responded and in that reminder letter an online version of the questionnaire was offered. We calculated that a response of 340 would be required for 95% confidence intervals of reasonable width. For the first survey in 2014, there were 385 responses in total (12. For the second survey in 2016, there were 380 responses (12. The 18-month interval between the two surveys was designed to allow tracking of unfolding events and the maturation of the CCGs; thus, a longitudinal element was enabled. We analysed key features of the non-responding CCGs, but there was no discernible pattern. They were distributed geographically and we could find no particular characteristic common features among the non-respondents that would distinguish them from those who did respond. In case of bias towards high-achieving CCGs, we compared our respondent CCGs with the profile of the 2016 NHSE ratings of CCGs. The very close match suggests that respondents from struggling CCGs were just as willing to respond to the survey as those from high-performing CCGs. The main in-depth case studies Following the pilot case study phase and the first national survey, the focus of research work shifted to the six main case studies. The selection of these core cases was informed, as planned, by the results from the first national survey and was also shaped by our knowledge of activity across potential case sites. We wanted geographical coverage so we ensured that the cases included CCGs in London, the Midlands and the North, and we also ensured coverage of urban and rural settings. Of special importance was our knowledge of the degree of service redesign activity occurring in these settings. A random selection of cases might easily have resulted in six CCGs characterised by relatively little activity. In order for us to be able to tease out the elemental processes of clinical engagement and leadership in service redesign, it was important to ensure that some of the cases had strong prima facie indications that they would be able to TABLE 1 The comparative distribution of survey respondents and the NHSE ratings profile 2015–16 NHSE ratings profile 2015–16 (%) CCGs sampled Inadequate Requires improvement Good Outstanding All NHSE CCGs 12 44 39 5 Our CCG sample 12 41 41 6 14 NIHR Journals Library www. Within each CCG we selected for detailed study one, or in some cases two, specific service innovations in particular areas. Within these cases there were also many research choices to be made. We used both purposeful sampling and theoretical sampling to access the most appropriate informants. First, we selected informants whom we expected would have the most relevant knowledge of the background issues affecting the CCG as a whole. This cluster was broadly common across the cases (accountable officer, CCG chairperson, clinical leads, and so on).
