Informed Consent in Biomedical Research: Scopes and Challenges

Medical science is evolving constantly and this evolution cannot happen without biomedical research involving human participant. Owing to a tumultuous history, importance of ethical research cannot be over emphasized in today's world and the concept of informed consent becomes the guardian of ethics, not only to improve the bonding between the participant and researcher aiding a wholehearted involvement but also ensuring safety for the participants from research related injury/loss. Subject information sheet (SIF) and Informed consent form (ICF) are the fundamental elements of informed consent document. Process of obtaining them from illiterate and vulnerable populations involves the legally authorized representative (LAR) and impartial witness. Audiovisual recording becomes important in case of clinical trials. Process of obtaining informed consent becomes challenging for vulnerable populations as well as during pandemic situations. A comprehensive informed consent is essential for a credible and ethical research.
