Views and experiences of participants and healthcare professionals to recruitment, randomisation and other features of the IIH Intervention Trial

To identify ways to facilitate the achievement of the recruitment target of the IIH host trial:

(1) for patients eligible to participate in the IIH Intervention trial, to explore their views and experiences of: recruitment approach, randomisation, barriers and facilitators to participation, and acceptability of treatment allocations;

(2) for healthcare professionals (HCP), to explore their views and experiences of recruitment, randomisation, including perceived barriers and facilitators, equipoise, appropriateness and acceptability of treatment allocations, and perceptions of trial processes.
