Respecting autonomy over time: policy and empirical evidence on re-consent in longitudinal biomedical research
2015-05-07T10:18:31Z (GMT) by
Re-consent in research, the asking for a new consent if there is a change in protocol or to confirm the expectations of participants in case of change, is an under-explored issue. There is little clarity as to what changes should trigger reconsent and what impact a re-consent exercise has on participants and the research project. This article examines applicable policy statements and literature for the prevailing arguments for and against re-consent in relation to longitudinal cohort studies, tissue banks and biobanks. Examples of re-consent exercises are presented, triggers and non-triggers for re-consent discussed and the conflicting attitudes of commentators, participants and researchers highlighted. We acknowledge current practice and argue for a greater emphasis on ‘responsive autonomy,’ that goes beyond a one-time consent and encourages greater communication between the parties involved. A balance is needed between respecting participants’ wishes on how they want their data and samples used and enabling effective research to proceed.
