## Content

NHS England published Version 2 of the Digital Technology Assessment Criteria (DTAC) on February 24, 2026. DTAC V2 establishes mandatory clinical safety and data protection standards for digital health tools deployed in NHS settings.

**Key compliance requirement:**
- All digital health tools used in NHS clinical workflows must meet DTAC V2 standards by **April 6, 2026**
- This is a mandatory compliance deadline, not a voluntary standard
- Covers: clinical safety, data protection, interoperability, usability

**Context within the 2026 regulatory landscape:**
- NIST AI Agent Standards Initiative (announced February 2026): agent identity, authorization, security as priority areas for standardization — but NO healthcare-specific guidance yet
- EU AI Act Annex III: healthcare AI high-risk classification, mandatory obligations August 2, 2026 (separate archive: 2026-08-02-eu-ai-act-healthcare-high-risk-obligations.md)
- Coalition for Health AI: advancing safety assessment methods with growing guidelines sets

**What DTAC V2 covers (general scope from context):**
- Clinical safety assessment for digital health products
- Data protection compliance (GDPR in UK context)
- Interoperability standards
- Usability requirements for NHS deployment

**Implication for clinical AI tools like OE:**
- If OE is used in NHS hospital or GP settings (UK has strong clinical AI adoption), DTAC V2 compliance is mandatory by April 6, 2026 (NOW, two weeks from the date of this session)
- DTAC V2's clinical safety assessment process would require documenting safety validation for OE's recommendations
- Any UK health system that deploys OE without DTAC V2 compliance is out of regulatory compliance

## Agent Notes

**Why this matters:** NHS DTAC V2 is the UK parallel to the EU AI Act — a mandatory regulatory standard that requires clinical safety demonstration for digital health tools. The April 6, 2026 deadline is happening NOW (two weeks from this session). If OE is deployed in NHS settings, compliance is required immediately. Unlike the EU AI Act (August 2026 deadline, international obligation), NHS DTAC V2 is already in effect with a deadline that is arriving in days.

**What surprised me:** The very short time between publication (February 24) and deadline (April 6) — 41 days — is aggressive. This suggests NHS England has been warning about DTAC V2 requirements for some time and the publication was the final version of something already signaled. Any digital health company operating in NHS settings should have been aware this was coming.

**What I expected but didn't find:** OE-specific DTAC V2 compliance announcement or NHS deployment status. OE's press releases focus on US health systems. Whether OE is used in NHS settings is unknown from public information, but the UK is a major clinical AI market and NHS deployment would trigger DTAC requirements.

**KB connections:**
- Companion to EU AI Act archive (2026-08-02-eu-ai-act-healthcare-high-risk-obligations.md): together these define the regulatory track that is arriving to close the commercial-research gap in clinical AI safety
- Relevant to Belief 3 (structural misalignment): regulatory mandate as a correction mechanism when market incentives fail — same pattern as VBC payment reform requiring CMS policy action rather than organic market transition
- Relevant to Belief 5 (clinical AI safety): DTAC's clinical safety assessment requirement would mandate the kind of safety validation that OE has not produced voluntarily

**Extraction hints:** Extract as a factual regulatory claim about NHS DTAC V2: mandatory clinical safety standards for NHS digital health tools, deadline April 6, 2026. Confidence: proven (regulatory fact). Secondary claim: the combination of NHS DTAC V2 (April 2026) and EU AI Act (August 2026) constitutes the first mandatory regulatory framework requiring clinical AI tools to demonstrate safety — creating external pressure that has not been produced by market forces. Confidence: likely (the regulatory facts are proven; the characterization as "first mandatory framework" requires checking for earlier analogous US regulations, which are less clear on clinical AI specifically).

**Context:** DTAC has been a voluntary standard in prior versions. V2 making it mandatory for NHS deployments is the significant change. The scope is broader than just AI — it covers all digital health tools — but AI tools are now the primary new entrant in NHS digital health, making this primarily relevant to clinical AI deployment.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: EU AI Act high-risk healthcare AI obligations — DTAC V2 is the UK parallel creating mandatory clinical safety assessment
WHY ARCHIVED: First mandatory UK clinical safety standard applying to digital health tools; companion to EU AI Act creating a 2026 regulatory wave that could force clinical AI safety disclosure
EXTRACTION HINT: Extract alongside the EU AI Act archive. Frame together as the "2026 regulatory wave": NHS DTAC V2 (April) and EU AI Act (August) represent the first regulatory framework requiring clinical AI safety demonstration in major markets. This is the structural mechanism that could force OE model transparency. Confidence for the regulatory facts: proven. Confidence for OE-specific implications: experimental (depends on whether OE is deployed in NHS settings).
