§ GUIDE · INFECTION

Pain out of proportion,
and nobody looked harder

Necrotising fasciitis, deep abscesses and post-operative infections move fast, and the published judgments show the same two failures: a clinician who did not suspect infection, and a ward that did not act once it was suspected. Three of the seven judgments here succeeded. The four losses show how hard causation is when infection is already established.

§ BEFORE YOU GO FURTHER

For a missed infection claim to get anywhere, these things usually need to be true

  • You had signs a clinician should have linked to serious infection: pain out of proportion to what could be seen, fever, a fast-spreading area, or a wound in a diabetic.
  • You were sent home, or antibiotics, scans or surgical review were delayed once you were in hospital.
  • Earlier antibiotics or surgery would probably have avoided the amputation, the organ damage or the death.
  • It happened within the last three years, or you only recently found out.

Two of the losses here accepted the care was poor but found the outcome would have been the same. The timing of the first warning sign against the timing of treatment is what a solicitor needs.

§ 01

Sent home from A&E or the GP

Macaulay v Karim: a diabetic man attended A&E with fever and rectal pain, a possible abscess was noted, and he left before blood results without being properly investigated. He returned two days later in septic shock and lost his lower leg, toes and fingers. Liability was established against the Trust. MAN v St George's: a woman with extreme lower-leg pain was sent home by a nurse practitioner instead of being seen by a senior doctor; necrotising infection followed and she lost her leg. The Trust admitted negligence.

Canavan v Gaynor is the loss. A GP diagnosed a groin haematoma and sent the patient away with painkillers; days later necrotising fasciitis cost her a leg at the hip. The GP conceded admission would have saved the leg, but the court found his examination and diagnosis were ones a reasonable body of GPs would support.

§ 02

Delayed on the ward

Dalchow v St George's: after routine removal of a scrotal cyst, a man returned in severe pain; intravenous antibiotics and an ultrasound were delayed, and Fournier gangrene cost him both testicles. The judge found breach of duty but held the delays could not be shown to have changed the outcome. Barnett v Medway: no blood cultures before antibiotics and no monitoring of inflammatory markers were basic failures, but the court was not satisfied they caused the spinal infection that left him paraplegic. Long v Western Sussex: discharge without repeat blood tests after a femoral fracture repair was a breach, but there was no evidence it made the infection worse.

§ 03

Infection caused by the procedure

MJF v University Hospitals Birmingham: a feeding tube fixed under too much tension caused necrosis, peritonitis and sepsis, with four months in intensive care. The judge rejected the doctor's account of how the tube had been fixed and entered judgment for the claimant. Where the infection is the direct result of a negligent technique, causation is much easier.

§ 04

What a solicitor will want

The observations and notes from the first attendance, especially any record of pain, temperature and heart rate. Blood results and when they were reviewed. The time antibiotics were prescribed and the time they were given. For necrotising fasciitis, the hours between first presentation and surgery decide the case.

§ THE JUDGMENTS BEHIND THIS GUIDE

The seven judgments behind this guide.

Every one a published decision of the courts of England and Wales, linked to its source. Four losses and three wins.

Claimant succeeded

Macaulay v Karim & Anor

[2017] EWHC 1795 (QB)·2017·Liability decided at trial

A 53-year-old diabetic attended A&E with fever, rectal pain and urinary difficulty; a possible abscess was noted but he left before blood results and was not properly investigated. He returned two days later in septic shock and lost his lower leg, toes and fingers; the court found that proper care at the first attendance would have avoided the amputations.

Diabetic patients with fever and localised pain need prompt investigation for a source of infection. A&E is responsible for ensuring a possibly septic patient is not allowed to leave without a plan.

Mixed outcome

MAN v St George's University Hospital NHS Foundation Trust

[2024] EWHC 1304 (KB)·2024·Liability decided at trial

A woman went to A&E with extreme lower-leg pain and was sent home by a nurse practitioner instead of being seen by a senior doctor or referred to surgeons; she developed a necrotising soft tissue infection and lost her leg. The Trust admitted negligence but tried to rely on the nurse's evidence disputing how much pain she reported; the Master ruled that evidence inadmissible because the defence had never properly pleaded that dispute.

An NHS trust cannot admit negligence and then quietly contest the facts at trial without pleading them. Severe, out-of-proportion pain in a limb is a recognised warning sign of necrotising infection that calls for senior review.

Claim failed

Canavan v Gaynor

[2023] EWHC 1911 (KB)·2023·Liability decided at trial

A woman attended a GP drop-in clinic with groin pain after an injection had missed the vein; the GP diagnosed a haematoma and sent her away with painkillers, and days later she was admitted with necrotising fasciitis and her right leg was amputated at the hip. The judge found the GP's examination and diagnosis were ones a reasonable body of GPs would support, so the claim failed despite the defendant accepting that referral would have saved her leg.

Even where a devastating outcome and causation are accepted, a claim fails unless the clinician's decision fell outside what a responsible body of practitioners would have done. A properly documented history and examination that reasonably excluded infection was a complete defence.

Claim failed

Dalchow v St George's University NHS Foundation Trust

[2022] EWHC 100 (QB)·2022·Liability decided at trial

After routine day-case removal of a scrotal cyst, the claimant returned in the early hours in severe pain; intravenous antibiotics were not started when they should have been and an ultrasound request was delayed, and he was later diagnosed with Fournier gangrene, needing repeated surgery and losing both testicles. The judge found breach of duty but held the claimant could not prove the delays changed the outcome.

Proving that care fell below standard is only half the case: the claimant must also show the negligence made a difference. Where surgery would have happened at the same time anyway, delayed antibiotics or scans may not be shown to have caused the injury.

Claim failed

Barnett v Medway NHS Foundation Trust

[2015] EWHC 440 (QB)·2015·Liability decided at trial

A man with a bone disorder was admitted with leg pain, given antibiotics without blood cultures being taken first, and later discharged; weeks later he returned with a spinal infection and became paraplegic. The court found basic failures (no cultures, no monitoring of inflammatory markers) but was not satisfied they caused the paralysis.

Proving a hospital made mistakes is not enough; the claimant must show those mistakes probably caused the injury. Infection cases often turn on whether earlier detection would have changed treatment.

Claim failed

Long v Western Sussex Hospitals NHS Trust

[2016] EWHC 251 (QB)·2016·Liability decided at trial

After surgery for a broken femur at St Richard's Hospital, Chichester, the patient was discharged in April 2008 without arrangements to repeat his inflammatory-marker blood tests, and a deep infection was diagnosed later. The court found this discharge and a four-day debridement delay were breaches of duty, but there was no evidence they made his condition materially worse, so the claim was dismissed.

Discharging a patient without arranging follow-up blood tests can be a breach of duty, but compensation depends on showing the delay actually worsened the outcome.

Claimant succeeded

MJF v University Hospitals Birmingham NHS Foundation Trust

[2024] EWHC 3156 (KB)·2024·Liability decided at trial

A young woman with cerebral palsy had a PEG feeding tube inserted and was found unresponsive two days later with peritonitis and sepsis. The judge rejected the doctor's account of how the tube was fixed, found it was placed under too much tension, and entered judgment for the claimant.

Where a clinician's recollection is unreliable and contradicted by the physical evidence, the court can find a procedure was done negligently. Causation may still be limited where a pre-existing condition would have deteriorated anyway.

§ QUESTIONS

Common questions

I was sent home with painkillers and it turned out to be necrotising fasciitis.

Canavan and MAN are both that story, with opposite results. The difference was what was recorded at the consultation: in MAN extreme pain was reported and the Trust admitted negligence; in Canavan the GP's documented examination reasonably excluded infection.

The hospital delayed my antibiotics by hours.

Dalchow shows the difficulty. Breach was found, but the claim failed because surgery would have happened at the same time anyway. A solicitor needs expert evidence on what earlier antibiotics would have changed.

I am diabetic and lost my leg after an infection was missed.

Macaulay succeeded on exactly this. Diabetic patients with fever and localised pain need prompt investigation for a source of infection, and A&E must not let a possibly septic patient leave without a plan.

The infection came from the operation itself.

Then the question is whether the technique fell below the standard, as in MJF where a feeding tube was fixed under excessive tension. That is a surgical injury claim as much as an infection claim.

How long do I have?

Three years from the injury, or from when you first realised care fell short. For a death, the family has three years from the death.
