Informed consent in clinical research: policies and practices in Singapore

The policies and practices for obtaining informed consent from research subjects in clinical research play a vital role in determining a nation's success as a center for clinical research. The difficulty lies in the fact that while on the one hand, informed consent is a necessary pre-condition for ethical clinical research, a scrupulous observance of the guidelines for informed consent could, on the other hand, cripple medical research. Crippling of ethical medical research can be adverse to public interest, and consequently, unethical. Hence, a fine balance must be struck in the application of the guidelines for obtaining informed consent. This, in turn, would depend on the constitution and skill of research ethics committees who are appointed to consider and approve clinical research proposals. The discussion below addresses the above difficulty with recommendations that could further enhance Singapore's image as a regional clinical trial hub.
