Informed consent · Biobanks

Biobank consent is broken in one specific way, and the two proposed fixes contradict each other

Short answer

Broad consent deepened at the point of decision and dynamic consent maintained over time are competing answers to biobank reuse, resting on different accounts of what consent protects.

What happened

Two normative proposals address the same failure. Steinsbekk and colleagues argue broad consent is the right instrument for biobanks provided it is also deep — that protection of participants, not administrative convenience, is the test a consent model must pass. Kaye and colleagues argue for Dynamic Consent: interactive platforms that maintain communication with participants over time as research programmes change, rather than resolving everything at enrolment.

Why it matters

The disagreement is not procedural. Deep broad consent treats consent as an informed authorisation that can be made well once; dynamic consent treats it as a relationship that has to be maintained. Which failure mode you consider worse — an uninformed authorisation, or a participant who has lost track of what they joined — determines which fix looks right, and no amount of implementation detail settles it.

Evidence

Study type
Competing normative proposals in biobank research ethics
Sample
Conceptual arguments; neither proposal is accompanied by an empirical trial here
Journal
BMC Medical Ethics · peer reviewed
Replication
The disagreement is live in the literature and is not resolvable by replication, since the dispute is about what consent is for
Limitations
Neither paper measures participant understanding, recruitment or withdrawal under its model. Broad-consent definitions vary across jurisdictions, which makes empirical comparison harder still.

Primary study

Conflicting evidence

Asks the same question and reaches a different answer.

Before

Specific consent was the intuitive default, tied to a defined study whose aims the participant could be told at enrolment — which biobank reuse makes impossible in principle.

Now

Two developed alternatives exist and pull in opposite directions. Both are normative proposals rather than trials: neither has been shown to produce better-informed participants, and dynamic consent has not been shown to raise recruitment.
