MHRA Change Programme: SaMD Lifecycle & AI Work Packages

The eleven work packages across two streams — SaMD lifecycle reforms and AI-specific challenges — including qualification, classification, post-market vigilance, and Yellow Card reporting.

In October 2022, the MHRA published the Software and AI as a Medical Device Change Programme Roadmap — a programme to ensure regulatory requirements for software and AI are clear and patients are protected. The programme builds on wider UK medical device reforms and delivers bold steps toward a framework that protects patients while positioning the UK as a home of responsible innovation.

For Hong Kong healthcare professionals evaluating digital health products — especially those referencing UK conformity or international harmonisation — understanding this roadmap clarifies what manufacturers should demonstrate across the device lifecycle.

Two workstreams, eleven work packages

The change programme includes eleven work packages across two workstreams:

Stream 1: SaMD lifecycle (eight work packages)

Reforms across the classical software medical device lifecycle:

Work packageFocus
WP 1 QualificationWhat qualifies as SaMD; crafting intended purpose; clarifying "manufacturer"
WP 2 ClassificationRisk-proportionate classification rules aligned with IMDRF; "airlock" sandbox concept
WP 3 Premarket requirementsEssential requirements, best practice development, human-centred SaMD, data governance
WP 4 Post-marketVigilance signal detection, adverse incident guidance, change management, PCCPs
WP 5 Cyber secure medical devicesCybersecurity legislation and guidance; unsupported legacy software

Stream 2: AI-specific challenges (three work packages)

Addresses challenges AIaMD poses over and above classically programmed software:

Work packageFocus
WP 9 AI RigourGMLP mapping, standards, best practice AIaMD development, bias frameworks
WP 10 Project Glass BoxHuman-centred AIaMD; interpretability and transparency for safety
WP 11 Project Ship of TheseusAdaptivity — static, batch-trained, individualised, and continuous-learning models; PCCPs for AIaMD

Programme aims

Broadly, the change programme seeks to ensure that:

  • A. Requirements for software and AIaMD provide assurance that devices are acceptably safe and function as intended
  • B. Requirements for manufacturers are clear, supported by guidance and streamlined processes
  • C. Friction is reduced through alignment with NICE, NHS England, and international partners including IMDRF

MHRA emphasises international harmonisation — regulatory innovation that departs from global consensus can burden manufacturers and delay access to effective products.

Qualification and classification

WP 1 (Qualification) addresses lack of clarity on what qualifies as SaMD — distinguishing SaMD from wellbeing software, IVD software, medicines, in-house manufacture, and accessories.

WP 2 (Classification) reforms classification rules to align more closely with the IMDRF risk categorisation framework, ensuring rules are proportionate to patient and public safety while allowing flexibility for novel devices.

A well-crafted intended purpose is the cornerstone of compliance — failure to define it adequately impairs quality management, clinical evidence generation, and post-market surveillance.

Post-market vigilance and the Yellow Card scheme

WP 4 (Post-market) strengthens safety signal detection for SaMD. MHRA receives relatively few adverse incident reports for software; investigations indicate reportable incidents — including indirect harm — are often not reported.

Indirect harm may occur when a medical decision, action taken, or action not taken is based on information or results provided by the device. Guidance will clarify what constitutes a reportable adverse incident and emphasise populations within the intended purpose in vigilance processes.

Reporting incidents in the UK

Healthcare professionals and patients can report problems with any medical device — including SaMD — via the Yellow Card scheme or Yellow Card app:

  • England and Wales — Yellow Card scheme
  • Scotland — NHS National Services Scotland online incident reporting plus local systems
  • Northern Ireland — Northern Ireland Adverse Incident Centre plus local systems

For Hong Kong clinicians using UK-origin tools or participating in multi-site trials, understanding that vigilance reporting is expected for indirect as well as direct harm helps set appropriate local incident review processes.

AI work packages in brief

  • WP 9 delivered the joint GMLP guiding principles (October 2021) and continues mapping them to UK legal requirements and standards
  • WP 10 focuses on human interpretability — ensuring opacity of AIaMD is translated into safety and effectiveness concerns, emphasising human–AI team performance
  • WP 11 addresses adaptivity categories: static AIaMD (data drift), batch-trained updates, individualised models, and continuous learning on streaming data — linking to PCCPs

Practical takeaway for Hong Kong

When reviewing vendor documentation, map it against lifecycle stages the roadmap covers: qualification, classification, premarket evidence, post-market surveillance, cybersecurity, and — for AI products — GMLP alignment, transparency, and change management including PCCPs.
