Clinicians have good moral and professional reasons to contribute to pragmatic clinical trials (PCTs). We argue that clinicians have a defeasible duty to participate in this research that takes place in usual care settings and does not involve substantive deviation from their ordinary care practices. However, a variety of countervailing reasons may excuse clinicians from this duty in particular cases. Yet because there is a moral default in favor of participating, clinicians who wish to opt out of this research must (...) justify their refusal. Reasons to refuse include that the trial is badly designed in some way, that the trial activities will violate the clinician’s conscience, or that the trial will impose excessive burdens on the clinician.

When may a physician enroll a patient in clinical research? An adequate answer to this question requires clarification of trust-based obligations of the state and the physician-researcher respectively to the patient-subject. The state relies on the voluntarism of patient-subjects to advance the public interest in science. Accordingly, it is obligated to protect the agent-neutral interests of patient-subjects through promulgating standards that secure these interests. Component analysis is the only comprehensive and systematic specification of regulatory standards for benefit-harm evaluation by research (...) ethics committees (RECs). Clinical equipoise, a standard in component analysis, ensures the treatment arms of a randomised control trial are consistent with competent medical care. It thus serves to protect agent-neutral welfare interests of the patient-subject. But REC review occurs prior to enrolment, highlighting the independent responsibility of the physician-researcher to protect the agent-relative welfare interests of the patient-subject. In a novel interpretation of the duty of care, we argue for a “clinical judgment principle” which requires the physician-researcher to exercise judgment in the interests of the patient-subject taking into account evidence on treatments and the patient-subject‘s circumstances.
