Interviews with clinical staff
RECRUITMENT
We will aim to interview two to three staff considered ‘key informants’ in each study centre (e.g. research nurses/midwives, sickle nurse specialists, sickle haematologists and sickle obstetricians) to inform the definitive trial. Interviews will be conducted once the site recruitment phase has been completed (or if not possible, towards the end of the recruitment phase) to enable participants to have had adequate experience to reflect on the trial. Telephone interviews will be conducted; the duration of interviews will be approximately 30–45 min.Topic guides will be devised for the three sets of qualitative interviews. Consistent with inductive qualitative research, relevant topics that arise during interviews will be added to the topic guide.
