England Extends Martha’s Rule Across Every Emergency Department

Every hospital emergency department in England will adopt Martha’s Rule by March 2028 after a seven-trust pilot recorded 69 patient-, family- or staff-initiated escalation calls over eight months. Some reviews led to urgent surgery or transfer to intensive care, according to NHS figures reported on September 22.

The national expansion moves a patient-safety mechanism designed for hospital wards into a faster, more crowded and less predictable setting. It gives patients, relatives, carers and staff a dedicated route to request an urgent clinical review when they believe someone is deteriorating and their concern is not being heard. Waiting areas are explicitly included, an important detail because emergency patients can worsen before reaching a treatment bay.

The decision is consequential not only because of its reach, but because it turns observations from patients and families into a formal input to clinical operations. The phone number is the visible front end. Behind it, hospitals need an always-available review team, clear routing, reliable documentation and data capable of showing whether calls change care, reduce harm and reach people equitably.

A second channel for detecting deterioration

Martha’s Rule was created after the death of Martha Mills, 13, who developed sepsis at King’s College Hospital in London in 2021. Her parents repeatedly raised concerns about her worsening condition. A coroner later concluded that Martha probably would have survived if she had been transferred to intensive care earlier. The rule began rolling out in 2024 and is now available across acute inpatient sites in England.

The model has three linked elements. Patients are asked in a structured way how they feel and whether they are improving or worsening. Staff can seek a rapid review when their concern is not being acted on. Patients, families, carers and advocates also have direct, round-the-clock access to a review by a team outside the immediate care team. The commissioner’s guidance says the reviewer should be an experienced clinician with current skills in assessing acute deterioration.

That structure matters. Martha’s Rule is not simply a right to a routine second opinion about diagnosis or treatment. It is an escalation pathway for possible deterioration, designed to bypass communication failures or hierarchy when time may matter. The mechanism also recognizes that a person who knows the patient well may detect a small change before it appears in routine measurements.

Early data show action, not proven causation

Use of the ward-based pathway has risen rapidly. NHS data cited in September show 19,177 calls from September 2024 through July 2026, including a monthly record of 1,678 in July. An earlier 18-month dataset through February 2026 counted 12,301 calls; 4,047 helped identify deterioration and 524 patients were moved to intensive care, high-dependency care, a specialist hospital or a specialist ward, according to a data review.

Those figures are encouraging, but they do not prove that the pathway saved 524 lives. They describe clinical actions after escalation, not outcomes against a comparable group that lacked access to the rule. Calls are also self-selected: awareness, confidence, language, family presence and hospital promotion all affect who uses the service. The seven-trust emergency pilot was small, and the public information released so far does not provide detailed denominators, patient outcomes or site-by-site variation.

A 2026 analysis of 8,171 calls made between September 2024 and October 2025 adds another caution. It found that 64% were not primarily about acute deterioration, suggesting that the pathway is also surfacing communication, coordination and broader care concerns. That does not make those calls unimportant. It does mean call volume alone cannot measure clinical benefit, and hospitals need classifications that distinguish deterioration from other unmet needs.

Emergency departments change the operating problem

Inpatient wards usually have an assigned team, a defined bed location and repeated observations over time. Emergency departments have frequent handoffs, rapid turnover and patients moving between waiting rooms, assessment areas and corridors. Some people leave before treatment; others are admitted, transferred or discharged within hours. A safe escalation system must locate the patient quickly, identify the responsible team and deliver an independent review without creating ambiguity about who owns immediate care.

The scale of demand raises the stakes. England’s emergency departments recorded 241,061 more attendances from June through August 2026 than in the same months of 2025, according to national reporting. The Royal College of Emergency Medicine has warned that overcrowding and understaffing make missed deterioration more likely, even among skilled clinicians.

The pilot suggests the model can operate without adding clinical staff, but national implementation will test whether that remains true across hospitals with different volumes, layouts and critical-care capacity. A phone line is useful only if calls are answered promptly, reviewers are genuinely independent, and urgent findings translate into treatment. Hospitals will also need plans for patients who cannot use a phone, speak limited English, have cognitive or communication disabilities, or arrive without an advocate.

The information system behind the phone line

For HealthDataCon readers, the core challenge is informatics and governance. Each escalation should produce a structured record: who called, what change they observed, where the patient was, when the call was received, when review began, what the reviewer found and what action followed. That record should connect to the patient’s clinical record while preserving a national dataset suitable for safety monitoring.

Useful measures extend beyond total calls. Trusts should track calls per 1,000 emergency attendances, median time to answer and review, treatment changes, surgery or critical-care transfers, repeat calls, adverse outcomes after a call, and workload on review teams. They should also examine variation by age, sex, ethnicity, disability, language, deprivation and whether a patient had someone present to advocate for them. Without denominators and subgroup analysis, a rising call count could reflect better awareness, worsening communication or both.

The need for equity measurement is already visible. An independent interim evaluation found that only about one in three surveyed members of the public, patients and families knew about Martha’s Rule, with additional barriers among some minoritized groups. A separate single-hospital service evaluation of 168 patients and relatives in North Wales found 93% were unaware of a locally advertised escalation service. Neither result can represent every emergency department, but both show why posters and media coverage are insufficient.

Evaluation must travel with the rollout

The expansion will be phased, creating an opportunity to learn across sites rather than treat implementation as a one-time switch. The National Institute for Health and Care Research has funded a national study to assess how the rule works in practice, its effect on outcomes and inequalities, and its consequences for NHS services. The March 2028 deadline should not become a reason to suppress findings about burden, weak uptake or unintended effects.

Successful implementation will require co-design with patients, relatives and frontline clinicians, clear information in multiple formats, local champions and senior support. Those are the features emphasized by the Patient Safety Commissioner after research found that patients and relatives sometimes detect deterioration before professionals or early-warning systems, yet often struggle to escalate what they see.

Martha’s Rule offers a disciplined way to treat patient and family concern as safety data rather than anecdote. Its early numbers justify expansion, but not complacency. The national test is whether every emergency department can turn a call into a timely, independent clinical response—and whether the resulting evidence shows that the people most at risk can reach the pathway when they need it.
