Which item is not a moral requirement of clinical trials?

• A. Informed voluntary consent
• B. Independent panel review before start
• C. Risk minimized and acceptable balance
• D. Documented patient satisfaction

Answer: (D)

The main idea is that ethical protections in clinical trials center on respecting participants, providing oversight, and balancing risks and benefits. Informed voluntary consent ensures autonomy: participants must understand what they’re agreeing to and agree freely without coercion. Independent panel review (ethics oversight) provides an independent check on the study’s ethics and safety before it starts. Risk minimized and the risk–benefit balance must be acceptable, so the study design seeks to reduce harm and ensure potential benefits justify any risks.

Documented patient satisfaction, while valuable for improving care and study design, is not a fundamental moral safeguard. It does not address consent, independent oversight, or risk–benefit protections. It may reflect quality of experience, but ethical requirements focus on protecting participants and ensuring sound scientific and ethical conduct.
