Public health and service delivery programmes, interventions and policies are typically developed and implemented for the primary purpose of effecting change rather than generating knowledge. Nonetheless, evaluations of these programmes may produce valuable learning that helps determine effectiveness and costs as well as informing design and implementation of future programmes. Such studies might be termed ‘opportunistic evaluations’, since they are responsive to emergent opportunities rather than being studies of interventions that are initiated or designed by researchers. However, current ethical guidance (...) and registration procedures make little allowance for scenarios where researchers have played no role in the development or implementation of a programme, but nevertheless plan to conduct a prospective evaluation. We explore the limitations of the guidance and procedures with respect to opportunistic evaluations, providing a number of examples. We propose that one key missing distinction in current guidance is moral responsibility: researchers can only be held accountable for those aspects of a study over which they have control. We argue that requiring researchers to justify an intervention, programme or policy that would occur regardless of their involvement prevents or hinders research in the public interest without providing any further protections to research participants. We recommend that trial consent and ethics procedures allow for a clear separation of responsibilities for the intervention and the evaluation. (shrink)

In a recent issue of Journal of Medical Ethics, we discussed the ethical review of evaluations of interventions that would occur whether or not the evaluation was taking place. We concluded that standard research ethics frameworks including the Ottawa Statement, which requires justification for all aspects of an intervention and its roll-out, were a poor guide in this area. We proposed that a consideration of researcher responsibility, based on the consequences of the research taking place, would be a more appropriate (...) way delineate the scope of research ethics review. Weijer and Taljaard present a counterargument to our proposal, which we address in this reply. They claim that a focus on researcher responsibility will weaken the protection of research participants and link it to ‘unethical research’ and a ‘government experimenting on its own people’. However, the moral responsibility of researchers is defined in terms of the consequences of the research on human welfare and harm, not in opposition to it. Weijer and Taljaard argue that researchers must justify what they are studying whether or not they have any control over it and that governments must justify their programmes, including by demonstrating equipoise, to a research ethics committee if they implement them in a randomised way. We strongly disagree that this is a defensible way to define the scope of research ethics review and argue that this provides no further protections to research participants beyond what we propose, but places a potential barrier to learning from government programmes.
