Physician-Investigator, Research Coordinator, and Patient Perspectives on Dual-Role Consent in Oncology: A Qualitative Study

IMPORTANCE Classic statements of research ethics generally advise against dual-role consent in which physician-investigators seek consent for research participation from patients with whom they have preexisting treatment relationships. Yet dual-role consent is common in clinical oncology research, as studies are often conducted in close relationship with clinical care. OBJECTIVE To explore key stakeholders' perspectives on dual-role consent in clinical oncology trials. DESIGN, SETTING, AND PARTICIPANTS This qualitative study with 43 participants was conducted at a National Cancer Institute-designated comprehensive cancer center from 2018 to 2022. Semistructured qualitative interviews of physician-investigators, research coordinators, and patients were performed. Respondents were recruited from 3 populations: (1) physician-investigators engaged in clinical oncology research; (2) research coordinators engaged in clinical oncology research; and (3) patients, with and without prior clinical trial experience, who had received a new cancer diagnosis at least 2 months prior to enrollment in this study. MAIN OUTCOMES AND MEASURES Interviews were audio recorded and professionally transcribed. A thematic analysis approach was used to develop a codebook that included both theory-driven, a priori codes and emergent, inductive codes. Two authors double-coded all transcripts and met regularly to compare coding, discuss discrepancies, refine the codebook, and draft memos describing relevant themes and their frequency. RESULTS Among the 43 respondents, 28 (65.1%) were female; 9 (20.9%) were African American, 8 (18.6%) were Asian, 6 (14.0%) were Hispanic, and 21 (48.8%) were White; 15 were physician investigators (6 [40.0%] with 6-10 years of experience, 4 [26.7%] with at least 20 years of experience), 13 were research coordinators (5 [38.5%] with 0-5 years of experience, 5 [38.5%] with 6-10 years of experience), and 15 were patients (9 [60.0%] aged 46-64 years). Four main themes were found: interviewees (1) perceived greater potential for role synergy than for role conflict; (2) reported dual-role consent as having mixed effects on the consent process, increasing prospective participants' understanding and likelihood of agreement while also challenging voluntariness; (3) preferred a team-based approach to the consent process in which physician-investigators and research coordinators share responsibility for communicating with prospective participants and safeguarding voluntariness; and (4) offered strategies for managing tensions in dual-role consent. CONCLUSIONS AND RELEVANCE This qualitative study found that concerns about dual-role consent in clinical oncology, while valid, may be outweighed by corresponding advantages, particularly if appropriate mitigation strategies are in place. These findings support a team-based approach to informed consent, in which physician-investigators and research coordinators promote both the understanding and voluntariness of prospective participants.
