The ethical cornerstone of human research is undergoing a digital transformation

In short: Since 1964, the Declaration of Helsinki has been the global gold standard for medical ethics. But as artificial intelligence and massive biobanks reshape science, the world’s most recognized ethical principle is facing an acute challenge from the era of big data.

First adopted by the World Medical Association in 1964, the Declaration of Helsinki (DoH) serves as a fundamental ethical norm for research involving humans. While not a legally binding instrument under international law, its authority stems from its widespread codification into national and regional regulations. The principle dictates that protecting a volunteer's well-being is more vital than scientific or communal gains, with moral duties superseding even regional legislation when a greater level of safety is possible.

The document is currently undergoing a significant revision process, a journey that began in April 202 and seeks to address the drastic changes in the scientific environment over the last decade. A primary focus of these amendments is the rise of data-driven research. With the rapid development of artificial intelligence and the use of real-world data from clinical practice, researchers are increasingly relying on secondary uses of information. This has created a pressing need to clarify the link between the DoH and the Declaration of Taipei, which governs health databases and biobanks.

Newer ethical frameworks are moving toward 'broad informed consent' and 'dynamic consent.' Unlike traditional methods, broad consent allows for the multipurpose use of data, while dynamic consent utilizes advanced information technology to allow participants to manage their rights—such as the right to know or not to know incidental findings—and the ability to withdraw their data from specific subsets. Planned revisions also seek to advance open science by incentivising the exchange of individual participant data (IPD) and guaranteeing that all subjects can access the most effective proven treatments after a trial concludes.
