Broad Consent
Broad consent is a form of permission that allows a person's identifiable data or biological samples to be stored and reused for a range of future research purposes, rather than seeking fresh consent for each individual study. It is designed mainly for research contexts, and its meaning and requirements differ between the United States and the European Union. Because it authorizes uses that are not fully specified at the time consent is given, it operates under conditions intended to keep those future uses within recognized ethical boundaries.
Broad consent is a distinct, alternative consent mechanism for the storage, maintenance, and secondary research use of identifiable private information or identifiable biospecimens. Under the U.S. revised Common Rule, broad consent is an optional pathway introduced for such research use that permits researchers to reuse identifiable data and biospecimens without obtaining study-specific informed consent for each subsequent use; it is not equivalent to, and does not replace, standard informed consent, and it applies only within the scope of that regulatory framework. In the EU context, the concept is discussed in relation to consent under the GDPR, where Recital 33 acknowledges that data subjects may consent to certain areas of scientific research when in keeping with recognized ethical standards, subject to the GDPR's broader consent conditions. Implementations vary: some frameworks describe a one-time approval covering pseudonymized health data and samples for varied future research. Practitioners should note that broad consent is a legal-basis and ethics construct specific to research reuse, that U.S. and EU regimes treat it under different instruments and are not interchangeable, and that interpretation of when it may be relied upon continues to evolve. This entry does not address specific IRB or ethics-committee approval requirements, and application to particular circumstances requires professional judgment against the current authoritative text in the relevant jurisdiction.
Why it matters
Broad consent addresses a practical tension in research: study-specific informed consent, obtained afresh for each new use, is often impractical when identifiable data or biospecimens are stored for reuse across many future studies whose details are not yet known. By authorizing a defined range of future research purposes at a single point in time, broad consent allows biobanks, registries, and research infrastructures to reuse material without returning to each participant for every subsequent project. For compliance and research-governance professionals, understanding this mechanism is essential to structuring lawful, ethically sound reuse programs.
The stakes are heightened because broad consent is not a universal construct. In the United States, it is an optional pathway introduced under the revised Common Rule specifically for the storage, maintenance, and secondary research use of identifiable private information or identifiable biospecimens. In the European Union, the concept is discussed in relation to consent under the GDPR, where Recital 33 recognizes that data subjects may consent to certain areas of scientific research when in keeping with recognized ethical standards. These are different instruments under different legal regimes, and they are not interchangeable. Treating a U.S. Common Rule broad consent as satisfying GDPR conditions, or vice versa, risks a compliance gap.
Because broad consent authorizes uses that are not fully specified when consent is given, its legitimacy depends on staying within recognized ethical boundaries and the conditions set by the applicable framework. Interpretation of when broad consent may properly be relied upon continues to evolve, and enforcement or ethics-review practice may diverge from a plain reading of the text. Organizations relying on it should verify their approach against the current authoritative source in the relevant jurisdiction and confirm that the specific reuses they contemplate fall within what the consent and the governing regime actually permit.
