§ GUIDE · ANTIBIOTIC DELAY

When antibiotics come too late,
the fight is over causation.

In sepsis and meningitis, hours matter. Hospitals often accept that antibiotics should have been given sooner. The real battle is usually whether the delay changed what happened. These judgments show how that question is decided.

§ WHY DELAY IS THE CLAIM

The failure is rarely the diagnosis. It is the clock.

Sepsis is the body's overwhelming response to infection, and it can kill within hours. Meningitis can move just as fast. Hospitals in England work to sepsis screening pathways that call for urgent recognition, escalation and intravenous antibiotics. A claim usually alleges that the screening was not done, the deterioration was not escalated, or the antibiotics that were prescribed were not actually given for hours.

That kind of failure is often accepted. In Davies v Frimley Health NHS Foundation Trust [2021] EWHC 169 (QB) the trust admitted that intravenous antibiotics should have started by 10.40 in the morning but were not given until 13.20. Mrs Davies died two days later of pneumococcal meningitis. Liability being admitted did not end the case: it left only causation to be tried.

§ THE CAUSATION QUESTION

Would earlier treatment have changed the outcome?

This is where sepsis claims are won and lost. The court asks whether, on the balance of probabilities, timely antibiotics would have saved the patient or reduced the harm. It is a question for expert evidence about how far the infection had already progressed.

In Davies the judge concluded that but-for causation was made out and the claim succeeded. In Graham v Dr Altaf [2023] EWHC 156 (KB), by contrast, a three-year-old was diagnosed with tonsillitis by a GP registrar and turned out to have meningococcal meningitis; the court found no causative breach of duty and dismissed the claim. Early meningitis genuinely resembles common childhood illness, which makes both breach and causation hard to prove against a GP.

§ MATERIAL CONTRIBUTION

You may not have to prove the delay caused everything.

Where an injury develops cumulatively, a claimant may succeed by showing the negligence made a material contribution to it, rather than proving the whole injury would have been avoided. Williams v The Bermuda Hospitals Board [2016] UKPC 4 is the case usually cited: a patient with appendicitis waited hours for a CT scan and surgery, his appendix ruptured, and sepsis damaged his heart and lungs. The Privy Council held the hospital's delay materially contributed to the injury even though some harm would have occurred anyway.

It is a Privy Council decision from Bermuda, so persuasive rather than binding here, but it is regularly relied on in delayed-treatment claims in England and Wales.

§ ADMISSIONS STICK

A trust that admits liability cannot easily take it back.

In Somoye v North West Anglia NHS Foundation Trust [2023] EWHC 191 (KB) a doctor died of abdominal sepsis and multi-organ failure a week after a myomectomy. The trust's own root cause analysis found failures to act on signs of infection and to follow the sepsis pathway, and it admitted liability before proceedings began. It later applied to withdraw that admission on fresh expert evidence. The court refused and entered judgment for her husband, with damages to be assessed.

For families, that matters: an early admission, often made after an internal investigation, is a serious step that the court will hold a defendant to.

§ INFECTION OF THE BRAIN

Fever, headache and confusion are a red flag.

Gahir v Dr Ola [2024] EWHC 390 (KB) concerned herpes simplex encephalitis, a brain infection, treated 55 hours late after a GP diagnosed migraine. The judge found the combination of fever, severe headache, nausea and confusion required urgent hospital admission, and that with earlier treatment the claimant would have been far less disabled. He was left with permanent brain damage and lost the capacity to manage his own affairs.

The case is a reminder that time-critical infection claims are not only about sepsis pathways in hospital. They can start in a GP surgery.

§ THE JUDGMENTS BEHIND THIS GUIDE

Five judgments on delayed treatment of infection.

Two hospital claims that succeeded, a Privy Council authority on material contribution, and two claims against GPs that went opposite ways.

Claimant succeeded

Davies v Frimley Health NHS Foundation Trust

[2021] EWHC 169 (QB)·2021·Liability decided at trial

Mrs Davies was admitted to Wexham Park Hospital with pneumococcal meningitis; the trust admitted intravenous antibiotics should have started by 10.40 but were not given until 13.20, and she died two days later. After a causation trial the judge found she would probably have survived with timely antibiotics.

In sepsis and meningitis claims a delay of even a few hours in giving IV antibiotics can be negligent, and the key dispute is often whether the delay changed the outcome. Here the family succeeded, with damages already agreed.

Claimant succeeded

Gbolahan O Somoye v North West Anglia NHS Foundation Trust

[2023] EWHC 191 (KB)·2023·Liability decided at trial

Dr Somoye died of abdominal sepsis and multi-organ failure a week after a myomectomy; the trust's own root cause analysis found failures to act on signs of infection and to follow the sepsis pathway, and it admitted liability before proceedings. The court refused to let the trust withdraw that admission and entered judgment for her husband, with damages to be assessed.

A pre-action admission of liability is binding unless the court permits withdrawal, and later-obtained expert evidence will not usually justify that. Failing to follow a hospital sepsis pathway is a recognised basis for a claim.

Claimant succeeded

Williams v The Bermuda Hospitals Board

[2016] UKPC 4·2016·Appeal decision

A patient with appendicitis waited hours for a CT scan and surgery; by the time his appendix was removed it had ruptured and sepsis had damaged his heart and lungs. The Privy Council held the hospital was liable because its delay materially contributed to the injury, even though some harm would have occurred anyway.

Where negligent delay makes an existing condition worse in a cumulative way, a claimant need not prove the whole injury would have been avoided, only that the delay made a more-than-negligible contribution. This is often relied on in sepsis and delayed-treatment claims.

Claimant succeeded

Gurmukh Gahir v Dr Ayodele Olusgun Ola

[2024] EWHC 390 (KB)·2024·Liability decided at trial

Mr Gahir went to his GP with fever, severe headache, nausea and confusion; the GP diagnosed migraine, and he was not admitted to hospital until 55 hours later, when herpes simplex encephalitis was treated with acyclovir. The judge found the combination of fever, headache and confusion required urgent hospital referral and that earlier treatment would have left him far less disabled.

Fever, headache and confusion together are a recognised red flag for brain infection, and a GP who attributes them to migraine without arranging urgent admission may be found negligent. The judge accepted the family's account of the patient's confusion during the consultation.

Claim failed

Edward Graham v Dr Simone Altaf

[2023] EWHC 156 (KB)·2023·Liability decided at trial

A three-year-old was diagnosed with tonsillitis by a GP registrar, deteriorated over the next two days and was then referred to hospital, where meningococcal meningitis was diagnosed. The court found no causative breach of duty and dismissed the claim.

Meningitis claims against GPs often fail because early symptoms genuinely resemble common childhood infections; the claimant must show both that the GP fell below a reasonable standard and that earlier referral would have changed the outcome.

§ QUESTIONS

Common questions

How quickly should antibiotics be given for suspected sepsis?

NHS sepsis pathways treat it as an emergency requiring urgent screening, escalation and intravenous antibiotics. In Davies v Frimley Health the trust admitted antibiotics should have started by 10.40 and were not given until 13.20, a delay of under three hours that the court found made the difference.

The hospital admitted it should have acted sooner. Have we won?

Not yet. Admitting the delay settles breach of duty, but you still have to show the delay caused or materially contributed to the harm. That is what the trial in Davies was about.

What is material contribution?

Where harm builds up cumulatively, it can be enough to show the negligence made a more-than-negligible contribution, rather than proving the whole injury would have been avoided. Williams v The Bermuda Hospitals Board is the case usually cited.

Can a trust withdraw an admission of liability?

Only with the court's permission, which is not easily given. In Somoye v North West Anglia the trust's application to withdraw was refused and judgment was entered for the family.

Can I claim against a GP for missing meningitis?

It is possible but difficult, because early symptoms resemble ordinary infections. Graham v Dr Altaf failed on that basis. Gahir v Dr Ola succeeded because fever, headache and confusion together are a recognised red flag for brain infection.

How long do we have to bring a claim?

Usually three years from the negligent treatment or from when you first knew something had gone wrong. For a death, three years from the date of death or knowledge. See our guide to time limits.
