PLENA Healthcare Consent Attestation
Informed consent the patient controls, that survives institutional handoff. Built for clinical trials, surgical procedures, genetic testing, reproductive-health decisions, advance directives, organ donation, and any healthcare decision where the question "did the patient understand, and did they consent" must be answerable years later.
Opening problem
The global clinical trials market alone runs roughly eighty billion US dollars annually. The broader informed-consent surface area — every elective procedure, every genetic test, every reproductive-health decision, every advance directive, every organ donation, every psychiatric admission — is far larger. In each case, the central question is the same: did the patient understand what was being asked, did they have the capacity to decide, did they consent freely, and is there a record that will hold up to scrutiny years later when memory fades, when institutions reorganize, when complications arise, or when the patient can no longer speak for themselves.
The existing infrastructure for this question is sponsor-controlled. Pharmaceutical sponsors and hospitals use systems like Medidata Rave, Veeva Vault, and Oracle Health Sciences eConsent — sophisticated platforms designed to satisfy regulators, oriented toward the institution's compliance posture rather than the patient's autonomy. These systems work for what they are built to do. They are not built to be patient-held. They are not built to survive the sponsor's bankruptcy, the hospital's closure, the transfer of care to a different institution in a different country, or the patient's loss of access to the platform that held their consent record.
PLENA Healthcare Consent Attestation is built for the patient's side of the consent transaction — the part that is structurally underserved. Not as a replacement for sponsor-controlled compliance systems, which serve a legitimate purpose, but as the layer those systems do not produce: a patient-held, multilingual, capacity-attested, refresh-disciplined record of what was understood, what was consented to, and what was refused, in a form the patient or their proxy can present to any future institution, regulator, or court.
Five cases PlenaProof covers
For each case, three actors share the work: the patient (or their proxy) makes the declarations, named witnesses (qualified attestor — clinician, ethics committee member, or designated witness depending on jurisdiction) attest, and PLENA seals the four-artifact bundle. Every artifact is an existing PLENA receipt format applied to a specific healthcare consent need — no new platform, no new identity layer.
Initial Informed Consent Attestation
Witnessed multilingual consent packet captured at the moment of signing, with capacity attestation from a qualified attestor. Particularly important for cognitively challenging studies (psychiatric, dementia, pediatric assent) where PLENA's existing Capacity Attestation methodology applies directly.
- Consent Declaration with Capacity Attestation. Sealed declaration recording the patient's consent, with a named clinician's or ethics-committee witness's attestation that the patient had capacity to decide.
- Sealed Comprehension Evidence Packet. Materials the patient received, language they were presented in, time spent, questions asked and answered.
- Initial Yearbook. First-year record of the consent decision and any follow-up.
- Multilingual Patient Handover Packet. Releasable by the patient to any subsequent provider, in host-country and patient-language formats.
Comprehension Verification Refresh
Periodic re-attestation that the participant still understands what they consented to and still consents. Critical for long studies, ongoing treatments, advance directives whose underlying decisions may need revisiting, and pediatric studies as participants age.
- Refresh Consent Declaration. Sealed periodic statement confirming continued comprehension and continued consent.
- Updated Comprehension Evidence. Any new information shared with the patient since the prior refresh.
- Annual Yearbook. Year-over-year continuity record.
- Multilingual Handover Packet. Releasable by the patient at any refresh point.
Adverse Event and Withdrawal Receipts
Patient-held documentation of any adverse events the patient experienced, complaints filed, decisions to withdraw, and the institutional response. Independent of sponsor-controlled safety reporting, which the patient does not control and may not be able to access in real time.
- Adverse Event Declaration. Sealed patient account of the event, in the patient's own words and language.
- Sealed Evidence Packet. Medical records the patient holds, photographs where appropriate, correspondence with sponsor or institution.
- Continuity Refresh. Periodic update on the unresolved status of the event.
- Multilingual Handover Packet to subsequent care providers. So the next clinician reads the patient's account, not just the sponsor's.
Surrogate and Proxy Authority Attestation
When consent comes from a guardian, parent, healthcare proxy, or surrogate, PLENA documents that authority's standing, the conditions under which it applies, and any limits the patient (when capable) placed on it. Critical for advance directives, end-of-life care, pediatric care, and care of incapacitated adults.
- Surrogate Authority Declaration. Sealed record of who the surrogate is and the scope of their authority.
- Sealed Evidence of the Underlying Authority Document. Power of attorney, advance directive, court order, or other legal basis.
- Refresh Yearbook. Confirms the authority still applies and surfaces any changes.
- Multilingual Handover Packet to receiving institution. Drafted to satisfy the receiving institution's intake.
End-of-Study and Long-Term Follow-Up Continuity
Receipts that follow the patient across institutional handoffs after a trial concludes, after a procedure is performed, or after a decision is implemented. Designed for the long tail of healthcare consent: the patient who needs to demonstrate, fifteen years later, that they consented to a specific procedure, or who needs to provide a successor institution with the consent history of a previous one.
- Continuity Declaration. Sealed statement of the patient's standing relative to the original consent decision.
- Sealed Long-Term Archive. All prior receipts bundled, plus any subsequent events.
- Periodic Refresh. Annual or trigger-driven re-attestation.
- Multilingual Handover Packet. Drafted to be readable by any future provider, regulator, or court.
Institutional version
A parallel set of artifacts for clinical research sites, ethics committees, sponsors, and IRBs.
Aggregated attestation for clinical research sites, IRB/ethics committee population-level summaries, audit-grade receipts that satisfy regulators while preserving patient control. Target buyers: major academic medical centers (Mass General Brigham, Johns Hopkins, NIH, Karolinska Institute, Oxford, Singapore General); mid-size pharmaceutical sponsors facing FDA Part 11 and EMA equivalent compliance pressure who cannot economically deploy full enterprise eConsent suites; Contract Research Organizations (CROs); patient advocacy organizations; WHO clinical trials registry; Real-World Evidence working groups at FDA and EMA; disease-specific patient organizations; IRB networks including WCG and Advarra.
Same complement-not-replace disclaimer. PLENA Healthcare Consent Attestation does not provide medical care, replace IRB review, store Protected Health Information as a primary system of record, or certify clinical research conduct.
The 100-Year Operating Commitment
Adapted for a population whose consent decisions outlive the institutions that recorded them.
PLENA Healthcare Consent Attestation is built on the assumption that the institution where consent was first obtained — the hospital, the sponsor, the platform — may not be the institution that needs to verify the consent decades later. Where actually implemented and populated, the intended architecture replicates each artifact produced here across multiple independent archives and anchors it cryptographically to public records that do not depend on the continued existence of any single institution, and verifiable offline by anyone holding the cryptographic keys. Receipts survive sponsor bankruptcy, hospital closure, electronic-records system migrations, and patient relocation to a different country and language.
Why this differs from sponsor-controlled eConsent
Systems like Medidata Rave, Veeva Vault, and Oracle Health Sciences eConsent are excellent for what they do: regulator-facing compliance documentation under sponsor control. PLENA Healthcare Consent Attestation is a different product addressing a different problem.
The differentiation is structural:
Ownership
Receipts owned by the patient, not the sponsor or institution.
Portability
Receipts travel across changes of provider, country, and care setting.
Persistence beyond institutional survival
Receipts remain accessible to the patient if the sponsor goes bankrupt or the hospital closes.
Multilingual by design
Supports patients whose primary language the sponsor's platform may not support well.
Capacity-attestation specialty
PLENA's existing methodology for cognitively challenging consent transactions applies directly.
Long-tail survivability
The consent record can be presented fifteen years later, when the original institution may be unreachable.
PLENA Healthcare Consent Attestation complements sponsor-controlled eConsent systems for any patient who has both. The two layers serve different parties.

What this does not do
PLENA Healthcare Consent Attestation does not provide medical care, treatment, or medical advice. It does not store medical records or Protected Health Information as a primary system of record. It does not replace Institutional Review Board or ethics committee review. It does not adjudicate medical malpractice claims. It does not function as medical insurance documentation. It does not replace the role of qualified healthcare professionals in obtaining and documenting consent. It does not certify clinical research conduct.
