“…Oncology was the most frequently mentioned clinical specialty [32, 34, 35, 38, 41, 43, 45, 48] and clinical trials were the most common type of research discussed [32, 34, 35, 37, 38, 41, 43-46, 48]. The term ‘researcher’ was not clearly defined, with some studies combining the views of recruiting doctors and nurses, principal investigators and trial managers [34], others looking solely at the perspectives of research assistants or associates [33, 38, 48], and others exploring the experience of research nurses [35, 44, 47] or scientists [40]. Similarly, the studies focused on a range of clinicians, including pharmacists [36], doctors [31, 32, 37, 41, 43, 44], midwives [39], nurses [46] and the whole multi-disciplinary team [45].…”
