A patient can deteriorate from a fever, confusion or severe pain within hours. When warning signs of sepsis are missed, concerns are dismissed, or urgent treatment is delayed, the consequences can be life-changing. Sepsis claims may be available where substandard medical care caused avoidable injury or made an existing illness significantly worse. Our medical negligence service supports patients and families across England who need clear advice after serious failures in care.
Sepsis is difficult to diagnose in some cases, particularly where symptoms are non-specific or the patient has other health conditions. A poor outcome does not automatically mean negligence. The central question is whether medical professionals acted to a reasonable standard at the time, and whether earlier or appropriate care would probably have avoided, reduced or shortened the harm.
When can a sepsis claim be made?
A sepsis negligence claim usually has two parts. First, it must be shown that a hospital, GP practice, ambulance service, urgent treatment centre or other healthcare provider breached its duty of care. Secondly, that breach must have caused an injury that would otherwise have been avoided.
The law does not expect clinicians to be perfect or to diagnose every condition immediately. It does require reasonable assessment, escalation and treatment in light of the symptoms, observations and information available. This can include taking a proper history, recording vital signs, recognising deterioration, ordering suitable tests, seeking senior input and giving antibiotics, fluids or critical care promptly where clinically indicated.
Examples that may justify further investigation include a patient being sent home despite escalating symptoms, abnormal observations not being acted upon, a delay in reviewing blood test results, or a failure to escalate concerns to a senior clinician. Delays in treatment after sepsis has been identified may also be significant. Each case turns on its medical records and expert evidence, not hindsight alone.
Claims against NHS trusts are usually handled by NHS Resolution under the Clinical Negligence Scheme for Trusts. Each claim is assessed on its own facts and evidence. Claims concerning private treatment follow the same core principles of proving breach of duty and causation.
Why proving causation matters in sepsis claims
Causation is often the most contested part of sepsis claims. Sepsis can progress quickly even with appropriate treatment, and a healthcare provider may argue that the outcome was unavoidable. A successful claim needs evidence showing that, on the balance of probabilities, proper care would have produced a materially better outcome.
That better outcome may mean avoiding death, amputation, organ damage, brain injury, scarring, prolonged intensive care, or a longer recovery period. It may also mean avoiding psychological injury following traumatic treatment and hospitalisation. In some cases, prompt care would not have prevented all harm but could have prevented part of it. The scope of any claim must reflect what the evidence can properly support.
Independent medical experts are normally asked to review the records and address the key questions: what should reasonably have happened, when should it have happened, and what difference would it likely have made? This evidence is essential before a case can be valued or resolved.
Evidence that can help establish what happened
Medical records provide the starting point. They may include GP notes, NHS 111 records, ambulance records, triage assessments, nursing observations, blood results, scan reports, prescription charts and discharge summaries. The timing of entries can be particularly important where a patient’s condition changed over several hours.
A detailed account from the patient or family can also help identify gaps that are not obvious from the notes. For example, relatives may recall repeated calls for help, a sudden worsening in breathing or alertness, or concerns that were raised but not documented. Keep any relevant letters, appointment details, photographs of injuries or scarring, receipts for care costs, and information about time away from work.
It is sensible to write down a timeline while events are still clear. Include when symptoms began, every contact with a healthcare service, what was said, whether advice was followed, and when sepsis was diagnosed. This does not replace formal records, but it can help ensure important questions are investigated.
What compensation may cover
Compensation in a sepsis claim is intended to put the injured person, so far as money can, in the position they would have been in without the negligence. It is not a punishment for the healthcare provider.
The claim may include compensation for pain, suffering and loss of amenity, as well as financial losses caused by the avoidable injury. Depending on the circumstances, this can cover past and future care, treatment and rehabilitation, adapted accommodation or equipment, travel expenses, loss of earnings, and assistance provided by family members.
Where a person has died, the legal position is different and depends on the relationship of the person bringing the claim, the losses suffered and the facts of the case. A careful assessment is needed before assumptions are made about entitlement. In a fatal claim, the time limit is usually three years from the date of death or the date of knowledge of the person bringing the claim.
There is no single average figure for a sepsis claim. Courts refer to published guidelines when valuing pain and suffering, but the value of each claim depends on the injury, prognosis and financial losses.
Time limits for bringing a claim
In most clinical negligence cases in England, court proceedings must be started within three years of the date of the injury or the claimant’s date of knowledge that an injury may have been caused by negligent treatment. The relevant rules appear in sections 11 and 14 of the Limitation Act 1980, available on legislation.gov.uk.
There are important exceptions. A child generally has until their 21st birthday to begin a claim. Where a person lacked the mental capacity to conduct proceedings when the claim arose, time does not usually start to run unless and until they regain capacity. Courts also have a limited discretion to allow a case outside the usual period, but this should never be relied upon.
Three years may sound generous, but serious sepsis cases take time to investigate. Records need to be obtained, the medical history reviewed and suitable independent experts instructed. Early advice gives the best opportunity to protect your position and preserve useful evidence.
What to expect from the claims process
The process begins with a careful review of the facts, records and the injury suffered. If the evidence supports a case, the healthcare provider is given a detailed account of the allegations and the losses being claimed. There is then an opportunity for investigation, a formal response and, where appropriate, discussions about settlement.
Some cases can be resolved without court proceedings. Others require further evidence or a court timetable because liability or the value of the claim is disputed. A serious injury claim should not be rushed simply to reach a quick figure. Future treatment needs, care arrangements and long-term impact must be understood before any settlement is considered.
Cooper Hall Solicitors can provide straightforward advice on whether the circumstances justify a full investigation. The priority is to establish the facts, protect your rights and give you a clear view of the steps ahead.
Frequently asked questions about sepsis claims
Can I claim if sepsis was diagnosed but treatment was delayed?
Possibly. Diagnosis alone is not enough if there was then an unreasonable delay in antibiotics, fluids, escalation, monitoring or admission to critical care. The key issue is whether the delay caused avoidable additional harm.
Can I make a claim for a relative who died from sepsis?
Potentially, but the right to bring a claim and the losses that can be recovered depend on the family relationship and circumstances. Legal advice should be sought promptly because evidence and time limits matter.
Do I need to know exactly what the hospital did wrong?
No. You do not need a medical diagnosis of negligence before asking for advice. A clear account of the events, together with the medical records, can be used to investigate whether care fell below an acceptable standard.
What if the sepsis began before I saw a doctor?
That does not prevent a claim. The question is whether the care provided after you sought help met a reasonable standard, and whether earlier recognition or treatment would probably have changed the outcome.
Will a complaint to the NHS stop me bringing a claim?
No. A complaint can provide answers and an apology, but it does not replace a legal claim or extend the usual limitation period. It is sensible to keep the two processes distinct and seek advice before time passes.
