Evolution of informed consent in research: From the Hippocratic Oath to the tailored consent

Abstract

Background: Informed consent (IC) is essential in defending the autonomy of potential participants in clinical research. Despite the advances in research ethics, particularly in IC, the different guidelines and codes have not been fully implemented. Several studies have presented consent deficiencies that have resulted in unethical practices or poor understanding of the IC.

Main body: This article reviews the evolution of IC, from its philosophical origins and initial use in the Ottoman Empire (16th century) to its use in clinical research today. It also presents the vision of the European project i-CONSENT (Grant Agreement number: 741856), whose main purpose is to improve the understanding of ICs in research and identifies the key components of a new paradigm to develop patient-centred ICs.

Conclusions: In many cases, the IC has served to protect the investigator or sponsor from complaints. Different ethical guidelines have sought to make the IC a more useful tool, with little success. Today's IC is mainly a bureaucratic and legal process that fails to consider the patient's point of view. In this context, the Guidelines for Tailoring the Informed Consent Process in Clinical Studies provide alternatives to the current IC process, focusing on the patient's opinions and making them part of the process, thereby improving clinical research quality.
