When a Hospital Error Leads to Life-Changing Consequences
Lessons from Dickinson v Newcastle Hospitals
What was the issue in the case?
In Dickinson v Newcastle upon Tyne Hospitals NHS Foundation Trust [2026] EWHC 1574 (KB), the Court considered a claim brought by a man who had been admitted to hospital in August 2016 for treatment of facial cellulitis and an abscess. The hospital accepted that it had failed to administer a full course of prophylactic Thiamine, also known as Vitamin B1, in the form of Pabrinex, despite the patient being alcohol-dependent and at recognised risk of alcohol withdrawal and Thiamine deficiency.
The consequences were extremely serious. The Claimant developed Wernicke’s Encephalopathy, a neurological condition linked to Thiamine deficiency, followed by severe functional neurological and cognitive symptoms and a depressive disorder. The Court recorded that he had developed profound physical disability, with a bleak prognosis for meaningful improvement.”
Although the hospital admitted that it had breached its duty of care, it denied that the breach had caused the Claimant’s current condition. This meant that the central issue for the Court was causation.
In clinical negligence claims, it is not enough to show that something went wrong. A claimant must also prove, on the balance of probabilities, that the negligent treatment caused the injury complained of, or caused a worse outcome than would otherwise have occurred. This can be difficult where the later condition is complex, develops over time, or involves both physical and psychological symptoms.
That was the important feature of Dickinson. The Court first had to consider whether the failure to administer Thiamine caused the Claimant to develop Wernicke’s Encephalopathy, a serious neurological condition linked to Thiamine deficiency. It then had to consider whether the experience and effects of that condition operated as a significant psychological stressor, triggering the Claimant’s functional neurological disorder. The Court accepted that chain of causation and held that, but for the failure to administer Pabrinex properly, the Claimant would not have developed the functional disorder.
Why is the case important?
For patients, families and practitioners, the case is a useful reminder that harm caused by negligent treatment may not be limited to the immediate physical consequences. Where the medical evidence supports the link, the Court may also find that negligence has caused a later functional condition, including one involving psychological mechanisms.
Functional neurological disorder, sometimes shortened to FND, can cause very real and disabling symptoms, including problems with movement, weakness, balance, cognition and daily functioning. In Dickinson, the Court accepted that the Claimant’s FND was not a coincidence and was not simply a pre-existing condition which had worsened for unrelated reasons. Instead, the episode of Wernicke’s Encephalopathy, and its effect on the Claimant, caused his functional disorder on the balance of probabilities.
In practical terms, the Court accepted a causal route where a negligent physical omission led to a serious neurological condition, which caused a psychological stressor, which in turn triggered a functional disorder. This is significant because patients with functional symptoms can sometimes feel that their condition is not taken seriously, particularly where investigations do not show clear structural damage. The judgment is a reminder that functional conditions can be genuine, disabling and, in appropriate cases, compensable.
The Court did not need to treat the functional disorder as a separate, free-standing psychiatric injury. It was treated as a further consequence of the admitted breach and the Wernicke’s Encephalopathy it caused. This reflects the “eggshell-skull” principle, meaning that if a claimant suffers a more serious or unusual injury because of their particular vulnerability, the defendant remains responsible for the harm actually suffered.
Damages in serious clinical negligence claims
The judgment also considered the scale of the Claimant’s losses, including future care, case management, equipment and accommodation. The parties’ positions on past and future losses, excluding pain, suffering and loss of amenity, were very far apart, with the Claimant’s case exceeding £5 million.
In clinical negligence claims, compensation is not limited to the injury itself. Where negligence causes life-changing disability, a claim may also include the cost of care, adapted accommodation, aids and equipment, therapies, loss of earnings and other practical support needed for the future.
What can patients and families take from this case?
Dickinson is a powerful example of how a failure to provide appropriate hospital treatment can have consequences extending far beyond the immediate admission. It also shows that complex causation arguments can succeed where the evidence supports a link between negligent treatment and the patient’s later condition.
For patients and families, the key message is that concerns about negligent medical care should not be dismissed simply because the injury is complicated, unusual or difficult to explain. Specialist legal advice can help identify whether there is a viable claim, what expert evidence may be needed, and what losses can properly be recovered.
