What you need to know
Short answerA sepsis negligence claim succeeds where clinicians failed to recognise and respond to the red-flag signs set out in NICE NG51 or to initiate the Sepsis Six bundle within an hour — and where expert evidence shows that earlier treatment would, on the balance of probabilities, have prevented the harm.
How sepsis claims typically arise
- GP misses red flags — patient sent home with viral infection diagnosis despite tachycardia, tachypnoea or confusion.
- Triage failure in A&E — high NEWS2 score but left waiting for hours without senior review.
- Delayed antibiotics — failure to give broad-spectrum IV antibiotics within one hour of recognition.
- Failure to escalate — junior staff don't call seniors; deteriorating observations not actioned.
- Missed post-operative sepsis — abdominal collection or wound infection not investigated.
- Discharge despite red flags — sent home from A&E or post-natal ward with sepsis evolving.
What you need to prove
Two questions are central: would competent clinicians have recognised and treated sepsis earlier (breach), and would that earlier treatment have prevented the harm — limb loss, organ failure, brain injury or death (causation)? Both require expert reports — usually emergency medicine plus a specialist in the injured system (e.g. nephrology for AKI).
Bereavement claims after a sepsis death
Where sepsis was fatal, dependants can bring a claim under the Fatal Accidents Act 1976 covering loss of dependency, plus the statutory bereavement award (£15,120 from 1 May 2020). The estate can also recover damages for the deceased's pain, suffering and financial losses up to death under the Law Reform (Miscellaneous Provisions) Act 1934.
Frequently asked questions
Can I claim if sepsis was missed or treated late?
Yes. Sepsis is a time-critical condition with clear UK guidance (NICE NG51 and the Sepsis Six pathway). Where doctors or nurses failed to recognise red-flag signs, missed deteriorating observations, or delayed antibiotics, and that delay caused avoidable harm — organ damage, amputation, or death — a clinical negligence claim is possible.
What are the sepsis red flags clinicians should spot?
Per NICE NG51: altered mental state, respiratory rate ≥25, heart rate ≥130, systolic BP ≤90, non-blanching rash, mottled or ashen skin, lactate ≥2, and not passing urine for 18 hours. Children and pregnant women have additional triggers. Failure to escalate when any red flag is present is a recurring theme in claims.
What is the Sepsis Six?
A UK Sepsis Trust care bundle — oxygen, blood cultures, IV antibiotics, IV fluids, lactate measurement and urine output monitoring — to be delivered within one hour of recognition. Failure to start the bundle promptly when sepsis is suspected is a frequent breach in claims.
How are damages calculated in sepsis claims?
Compensation reflects the difference between the actual outcome (e.g. amputation, brain injury, death) and what would have happened with timely treatment. The Judicial College Guidelines provide brackets for the relevant injury — amputation, AKI, brain injury — plus past and future care, loss of earnings and rehabilitation.
