1Department of Child Health, University of Queensland, Mater Children's Hospital, South Brisbane, Australia.
Insights
Most parents misunderstand clinical trial risks and informed consent procedures. Many do not realize trials assess safety and underestimate risks, impacting informed consent understanding.
Area of Science:
- Pediatric clinical trials
- Bioethics
- Patient informed consent
Background:
- Informed consent is crucial for ethical clinical research.
- Parental understanding of clinical trial protocols is essential for valid consent.
- Previous research indicates gaps in public comprehension of research ethics.
Purpose of the Study:
- To assess parental perceptions and attitudes towards informed consent in pediatric clinical trials.
- To identify specific areas of misunderstanding regarding the informed consent process.
- To evaluate parental awareness of risks, benefits, and rights in clinical research.
Main Methods:
- Qualitative study involving 64 parents post-clinical trial participation.
- Questionnaire-based interviews to gather perceptions and attitudes.
- Analysis of responses concerning trial objectives, risk perception, and consent procedures.
Main Results:
- A small minority of parents understood that drug trials assess both efficacy and safety.
- Most parents perceived hospital-conducted drug trials as low-risk.
- A significant minority found strict informed consent procedures unnecessary, deferring to physician advice.
- Few parents recognized consent forms protect their rights or knew of their right to withdraw.
Conclusions:
- Significant attitudinal barriers hinder parental comprehension of informed consent in pediatric clinical trials.
- There is a need for improved patient education regarding clinical trial processes and ethical considerations.
- Enhancing parental understanding is vital for ensuring truly informed consent and protecting participant rights.
Abstract:
We interviewed 64 parents by questionnaire after completion of a clinical trial involving their children for their perceptions and attitudes about informed consent. The results show that only a small minority realised that drug trials are designed to assess not only efficacy but safety as well. More worrisome was the majority of parents who felt that drug trials conducted by hospitals are of no or low risks. Moreover, a significant minority offered the view that the strict informed consent procedures we followed were unnecessary because they would do what the doctor advised. Even more worrisome was the small percentage of parents who realised that a signed consent form was primarily meant to protect their rights, and only one-third of the parents knew of their right to withdraw their child unconditionally from the trial at any time. These findings suggest that there may be significant attitudinal barriers to parental understanding of the informed consent process.
