Ethical Issues of Informed Consent: Mothers' Experiences Enrolling Their Children in Bone Marrow Transplantation Research

Twelve mothers whose children had undergone bone marrow transplantation were interviewed about their experiences giving informed consent. They were asked to describe how they were introduced to bone marrow transplantation as a course of action to treat their gravely ill children, what their understanding of the protocol was, and the process by which they gave their consent. Their stories reveal complex ethical issues that may surface in the course of informed consent for research involving children. Findings suggest that mothers perceive life-and-death circumstances when a child is offered bone marrow transplantation, altering the voluntary nature of the research enterprise. The emotional trauma of the diagnosis decreases a mother's ability to absorb and understand vital information, and the emergent nature of the children's condition and the urgency to begin treatment further compromise informed consent by constricting the time and resources mothers may need to make a decision. Once a protocol is underway, mothers often experience regrets and self-recriminations about their decision to consent. Recommendations are offered that expand upon the current cognitive/rational approach to informed consent and take into account emotional experiences and the importance of building relationships to ensure informed consent over the life of a clinical trial.
