Academic researchers and clinical academics were based in universities and specialist research institutes generic floxin 200 mg visa infection 8 weeks after miscarriage, in NHS hospital and community trusts and in specialist treatment and rehabilitation centres serving the NHS safe floxin 400mg antibiotics for sinus infection symptoms. As well as leading their own research and managing under- and postgraduate teaching programmes or large clinical caseloads, many had additional roles and responsibilities. Within their own organisations these included managing research strategy, building research capacity and capability, providing clinical and student supervision, and positions as heads of service and professional leads. Externally they included providing strategic leadership via active membership of networks such as the British Academy of Childhood Disability; the European Academy of Childhood Disability; NHS clinical governance networks and independent clinical advisory bodies; and organisations such as Disability Matters. A few had been members of guidance development groups for NICE.

Of those recruited who had a therapy background, all were members of their national professional body. Within these organisations, some were members of specialist sections providing professional direction and guidance to their members, such as the Specialist Section Children, Young People and Families of the RCOT and the Association of Paediatric Chartered Physiotherapists within the CSP. Of those who were members of the RCSLT, some were voluntary specialist advisors in their field of expertise and/or members of local Clinical Excellence Networks that meet regularly to share and develop common interests and expertise. In the same way, some of the paediatricians recruited held voluntary roles within the Royal College of Paediatrics and Child Health, such as on the Specialist Advisory Committee for Neurodisability. The largest group, from the North of England, was made up of nine people from the north-east and three from the north-west. Representatives from RCOT, CSP and RCSLT worked countrywide, as did two of the private practitioners. Practitioner focus groups: sample Forty-four therapists took part in one of six focus groups. Over half of these were physiotherapists, the smallest therapy profession represented among those interviewed individually. Most worked for the NHS in the community, predominantly in the north of England. Overall, the therapies they represented, and the organisation, type of setting and locations in which they were based, are reported in Table 6.

The practitioners had wide-ranging experience within physiotherapy, occupational therapy and speech and language therapy. The mean number of years that practitioners had been qualified was 14. Over 60% reported some previous experience of research, although this varied: investigator, involvement in delivering a programme under evaluation, research within undergraduate/postgraduate studies, service audit and/or membership of research discussion forums. These characteristics of the sample are reported in Table 7. BOX 2 Diagnostic groups represented in practitioner focus groups l Acquired brain injury. Parent focus groups: sample In total, four focus groups were conducted with 26 parents. Of these parents, 20 were mothers, five were fathers and one was a grandfather (Table 8).
