Results
In total 16 patients, 13 nurses, six practice managers, and one GP were interviewed. Patients were aged from 19 to 74 years (mean 56 years, standard deviation 15 years), seven were male and nine were female, and all identified as White British. Patients are designated by region (A, B, and C), sex (M or F) and age in years, for example, Patient AF57.Nurses are designated by number and whether they were a clinical research network nurse (CRN nurse) or practice nurse (Nurse). As a result of a lack of availability of nurses at specific practices, two regions utilised research nurses (employed by their local CRN rather than practice nurses). Local CRN research nurses covered >1 practice and therefore 13 nurse participants were interviewed.In two regions, practices formed consortia under one management group, so seven interviews were undertaken in the practice manager (six interviews) or GP (one interview) category.Themes are listed under implementation, mechanisms of impact, and contextual factors.
