Petrie-Flom Center analysis, March 5, 2026, examining the European Commission's December 2025 proposal to "simplify" medical device and AI regulation in ways that critics argue would remove key safety protections.

**Key developments:**
- December 2025: European Commission proposed sweeping amendments to MDR/IVDR as part of "simplification" effort, also amending the AI Act.
- Under the proposal: AI medical devices would still be within scope of the AI Act but would **no longer be subject to the AI Act's high-risk AI system requirements.**
- The Commission retained the power to adopt delegated/implementing acts to reinstate those requirements — but the default is now non-application.
- Key concern from Petrie-Flom: "Clinicians will still be expected to use AI safely, interpret outputs, and manage edge cases, yet the regulatory system will no longer guarantee that systems are designed to support meaningful human oversight."
- Industry lobbied for an even longer delay, citing "dual regulatory burden" as stifling innovation.
- **WHO explicitly warned of "patient risks due to regulatory vacuum"** (separate Health Policy Watch article).
- General high-risk AI enforcement: August 2, 2026. Medical devices grace period: August 2027 (16 months later).
- Grandfathering: Devices placed on market before August 2, 2026 are exempt unless "significant changes in design."

**The core tension:** Industry framing = removing "dual regulatory burden" to enable innovation. Patient safety framing = removing the only external mechanism that would require transparency, human oversight, and bias evaluation for clinical AI.

**US parallel:** FDA simultaneously (January 2026) expanded enforcement discretion for CDS software, with Commissioner Marty Makary framing oversight as something government should "get out of the way" on.

**Convergent signal:** Both EU and US regulatory bodies loosened clinical AI oversight in late 2025 / early 2026, in the same period that research literature accumulated six documented failure modes (NOHARM, demographic bias, automation bias, misinformation propagation, real-world deployment gap, OE corpus mismatch).

## Agent Notes
**Why this matters:** In Session 9 I identified the regulatory track (EU AI Act, NHS DTAC) as the "gap-closer" between the commercial track (OpenEvidence scaling to 20M consultations/month) and the research track (failure modes accumulating). This paper documents the gap-closer being WEAKENED. The regulatory track is not closing the commercial-research gap; it is being captured and rolled back by commercial pressure.
**What surprised me:** The simultaneous rollback on BOTH sides of the Atlantic (EU December 2025, FDA January 2026) suggests coordinated industry lobbying or at least a global regulatory capture pattern. The WHO's explicit warning of "patient risks due to regulatory vacuum" is striking — international health authority directly contradicting the regulators rolling back protections.
**What I expected but didn't find:** Evidence that the EU simplification maintains equivalent safety requirements through a different mechanism. The Petrie-Flom analysis suggests the Commission retained only a power to reinstate requirements, not an obligation — meaning the default is non-application.
**KB connections:** Belief 5 (clinical AI creates novel safety risks); Session 8 finding that EU AI Act was a "forcing function"; OpenEvidence opacity (already archived); all clinical AI failure mode papers (Sessions 7-9).
**Extraction hints:** (1) "EU Commission's December 2025 medical AI deregulation proposal removes default high-risk AI requirements — shifting burden from requiring safety demonstration to allowing commercial deployment without mandated oversight"; (2) "Simultaneous regulatory rollback in EU (Dec 2025) and US (Jan 2026) on clinical AI oversight represents coordinated or parallel regulatory capture"; (3) "WHO warning of 'patient risks due to regulatory vacuum' from EU AI Act simplification directly contradicts Commission's deregulatory framing."
**Context:** Published March 5, 2026 — directly relevant to current regulatory moment. Lords inquiry (April 20, 2026 deadline) and EU AI Act full enforcement (August 2026) are both imminent.

## Curator Notes
PRIMARY CONNECTION: Clinical AI failure mode papers (Sessions 7-9); EU AI Act enforcement timeline claim
WHY ARCHIVED: The "regulatory track as gap-closer" framing from Session 9 is now complicated — the regulatory track is being weakened. This is a significant Belief 5 update.
EXTRACTION HINT: New claim candidate: "Regulatory capture of clinical AI oversight is a sixth institutional failure mode — both EU and FDA simultaneously loosened oversight requirements in late 2025/early 2026 despite accumulating research evidence of five failure modes." Flag as a divergence candidate with existing claims about regulatory track as gap-closer.
