Martha's Rule: What It Means for Patient Safety in the UK

Martha Mills died in 2021, aged 13, after developing sepsis in hospital following a pancreatic injury. A 2023 coroner's inquest found she would probably have survived had she been moved to intensive care sooner — her family had repeatedly raised concerns about her deteriorating condition that were not acted on quickly enough. That case is now the basis of a patient safety right being rolled out across every NHS acute trust in England: Martha's Rule.

What Martha's Rule actually gives patients and families

Martha's Rule is built on a simple premise: the people who know a patient best — the patient themselves, their family, or their carers — are often the first to notice signs of deterioration, sometimes before it's obvious on a clinical chart. The initiative gives them, alongside staff, a structured route to trigger a rapid clinical review when they're worried, rather than relying solely on the treating team to recognise the change.

It has three core components: structured daily checks with patients and families about whether their condition has changed; a standing ability for staff to call in a second opinion from a different team, any time, if something feels wrong; and — the part that gives the initiative its name — a direct escalation route available to patients, families, and carers themselves, not just clinical staff.

Rollout timeline: where things actually stand

Martha's Rule was piloted from May 2024 at 143 sites across England. Phase 2 began in April 2025, expanding the initiative to all acute trusts. As of 2026, every acute trust in England is implementing some form of Martha's Rule, though coverage varies by site — some trusts currently run it only in specific wards or departments rather than hospital-wide. Full implementation across all acute trust inpatient services is targeted for completion during 2026/27, meaning this is still an active rollout rather than a finished, uniformly-applied policy.

Why this matters beyond acute hospital trusts

Martha's Rule is formally an NHS acute trust initiative, but its underlying principle — that escalation of a deterioration concern should never depend solely on whether the person noticing it has the authority to act on it — is directly relevant to care homes, domiciliary care, and any setting where staff, residents, or families might notice a change before it reaches a clinician. Compliance and training teams outside acute trusts should expect commissioners, CQC inspectors, and safeguarding leads to increasingly ask whether an equivalent escalation culture exists in their own settings, even where the formal Martha's Rule branding doesn't technically apply.

What providers should be doing now

• Don't assume "we already do this." Many providers have informal escalation cultures, but Martha's Rule requires a structured, known, and trusted route — not just an open-door policy that staff, patients, or families may not realise exists or feel confident using.
• Train staff on the "why," not just the process. The initiative exists because a family's specific, repeated concerns went unacted on. Staff need to understand that a family or carer raising a concern is a legitimate clinical signal, not an interruption to be managed.
• Check where your trust or provider actually stands in the rollout. Because implementation is phased and uneven across sites, staff moving between wards or services can't assume the same escalation process is live everywhere — this needs to be explicit, not assumed.
• Connect it to existing incident and deterioration documentation practice. A Martha's Rule escalation is only as effective as the documentation and follow-through behind it — the same evidence discipline that underpins good incident investigation more broadly.

How this compares to existing escalation routes

Most hospitals already had some form of rapid response team or outreach service that could be called for a deteriorating patient. What Martha's Rule changes is who is entitled to trigger that call. Previously, escalation to a rapid response or critical care outreach team typically depended on a member of staff recognising the deterioration and choosing to act. Martha's Rule makes the route explicit and available directly to patients and families, removing the dependency on a staff member being the one who notices, agrees, and decides to escalate on the family's behalf.

Frequently asked questions

Is Martha's Rule only for hospitals?
Formally, yes — it's an NHS acute trust initiative. But the underlying escalation principle is increasingly treated as a benchmark for deterioration and safeguarding practice across the wider health and social care sector.

When will Martha's Rule be fully rolled out?
Phase 1 launched at 143 pilot sites in May 2024, and Phase 2 expanded to all acute trusts from April 2025. Full implementation across all acute trust inpatient services is targeted for 2026/27 — coverage still varies by site in the meantime.

Who can use Martha's Rule to request a review?
Patients themselves, their families or carers, and staff can all request a rapid review from a different clinical team if they're worried about deterioration, independent of the treating team's own assessment.

Understanding patient safety initiatives like Martha's Rule is part of the wider compliance and clinical governance picture healthcare organisations need to stay ahead of. Learnsignal's CPD training library covers patient safety, incident escalation, and the documentation standards that sit behind initiatives like this, alongside the wider incident investigation and documentation standards healthcare providers are expected to meet.
