Martha’s Rule is one of the most significant patient‑safety reforms introduced into the NHS in recent years. It gives patients and their families the right to request an urgent clinical review by a separate team if they believe a patient’s condition is deteriorating and their concerns are not being acted upon. NHS England has confirmed that implementation across all acute inpatient settings is expected to be completed during 2026/27.

The initiative was developed following the death of 13‑year‑old Martha Mills, who died from sepsis in 2021 after her parents’ concerns about her deterioration were not escalated. A coroner later found she would probably have survived had she been moved to intensive care sooner.

For clinical negligence practitioners, Martha’s Rule represents a major shift in how deterioration, communication, and escalation failures will be assessed in future claims.

How Martha’s Rule Changes the Legal Landscape

A clearer standard for responding to patient and family concerns

Many clinical negligence cases arise from failures to recognise and escalate deterioration—particularly in sepsis, maternity care, and paediatrics. Martha’s Rule formalises the expectation that concerns raised by families must be listened to and acted upon. This creates a more explicit benchmark against which breach of duty may be assessed.

Where a family requests a rapid review and it is not carried out, that omission may now be scrutinised more closely as a potential breach of duty.

Stronger evidence trails

The Rule requires hospitals to implement transparent escalation pathways and document when concerns are raised. This may provide clearer evidence in litigation, including:

  • timelines of when concerns were expressed;
  • whether escalation occurred promptly;
  • whether the rapid‑review process was followed.

This documentation may support both claimant and defendant positions, depending on the facts.

Greater focus on systemic failures

Martha’s case highlighted not only clinical errors but also systemic communication failures. Martha’s Rule directly targets these issues by enabling escalation outside the usual hierarchy. As a result, future claims may place greater emphasis on:

  • organisational culture;
  • communication systems;
  • staff training and compliance with escalation protocols.

This may lead to more claims framed around systemic negligence rather than isolated clinical mistakes.

Potential Impact on Claim Volumes and Case Strategy

Likely increase in claims involving missed deterioration

As public awareness grows, more families may recognise when deterioration was not acted upon. This may lead to an increase in claims involving:

  • sepsis;
  • paediatric deterioration;
  • maternity complications;
  • emergency‑department delays.

The pilot phase of Martha’s Rule generated nearly 5,000 calls and 241 interventions that may have saved lives, demonstrating both the scale of unmet need and the potential for missed opportunities.

Earlier admissions of liability in some cases

With clearer escalation pathways and better documentation, some cases may be resolved earlier. Where failures to follow Martha’s Rule are evident, defendants may be more inclined to admit liability sooner, reducing litigation costs and delays.

What This Means for Patients and Families

Martha’s Rule empowers families to speak up when they believe something is wrong. It provides:

  • a clear route to request a second clinical opinion;
  • reassurance that concerns must be taken seriously;
  • a safeguard against communication failures that have historically contributed to avoidable harm.

For many families, this may prevent the very circumstances that often lead to clinical negligence claims.

What This Means for Healthcare Providers

Hospitals will need to ensure:

  • staff are trained to recognise and respond to escalation requests;
  • rapid‑review teams are available;
  • documentation is robust;
  • compliance with the Rule is monitored.

Failure to implement the Rule effectively may itself become a feature of future litigation.

Looking Ahead

Martha’s Rule marks a cultural shift within the NHS: a move towards transparency, accountability, and genuine partnership with patients and families. For clinical negligence practitioners, it will reshape how cases involving deterioration are investigated and argued. For patients, it offers a vital safeguard that may prevent avoidable harm.
