We've got your Medical Misdiagnosis Claim covered

Medical Misdiagnosis Claims

Misdiagnosis claims form the basis of the largest percentage of medical negligence compensation claims. The annual report from NHS Resolution indicated that there has been an increase of £0.2 billion for ‘potential claims arising from delays, cancellations and misdiagnosis.’ The consequences of misdiagnosis can be devastating and can lead to delays in patients receiving the treatment they require.

Suffering from a medical misdiagnosis? You’re not alone. We recognise the profound and enduring impact that misdiagnosis can have.

What is a Medical Misdiagnosis?

A medical misdiagnosis occurs when your GP, or another health professional, provides you with an inaccurate or delayed diagnosis. This can lead to incorrect treatment which can result in worsening of the condition, emotional distress, and avoidable expenses.

Whilst diagnosis may be difficult in some circumstances, a treating clinician has a duty to consider all reasonable causes for your condition and to take steps to exclude or confirm any potential diagnosis.

What is a Medical Misdiagnosis Claim?

A misdiagnosis claim occurs following an inaccurate or delayed diagnosis and involves a patient taking legal action against a healthcare provider. Patients pursue misdiagnosis claims to seek compensation for the damages caused by this breach in the standard of care. Decades of experience navigating misdiagnosis claims and securing compensation gives us a unique understanding of this area. We understand the complexities of medical misdiagnosis and will do everything we can to secure you justice.

What are the Different Types of Medical Misdiagnosis Claims?

We have handled many different medical misdiagnosis compensation claims, including:

Misdiagnosis claims can occur in many different forms but some of the most common that we see are:

  • A serious illness is allowed to progress unchecked or without being correctly identified
  • Wrong medication is prescribed due to the misdiagnosis of the condition. This could result in a worsening or prolonging of your ailment
  • Test results are misinterpreted or not properly assessed
  • Inadequate consideration is given to alternative or differential diagnoses
  • Treatment is delayed because of misdiagnosis so your condition gets worse
  • Misdiagnosis in pregnancy related cases can result in damage to the mother and to the unborn baby particularly in relation to a failure to recognise early signs of infection
  • Failure to diagnose a fracture: it could be that your fracture was missed during an X-ray or MRI, or that there was a failure to conduct adequate tests and investigations. A fracture misdiagnosis or delayed diagnosis could negatively impact the outcome of your treatment, increase recovery time, and in some circumstances lead to serious complications. In 2018, we helped our client to receive £17,500 by his NHS Trust after they failed to identify a stress fracture.

Claiming Cancer Misdiagnosis Compensation

Cancer misdiagnosis can have detrimental implications, particularly if the total misdiagnosis or delayed diagnosis impacts your long-term health or leads to additional medical costs.

This is a specialist claim type that requires dedicated legal expertise. Our solicitors are experts in medical negligence and have handled many cancer misdiagnosis claims successfully. Due to the intricate nature of cancer diagnosis, misdiagnosis or delayed diagnosis can unfortunately occur. A delayed or missed diagnosis can result in the cancer progressing and this limits the available treatment options. We can help investigate whether the cancer should have been identified sooner and assess the potential impact on your prognosis and treatment.

What Common Conditions are Misdiagnosed on the NHS?

Many common conditions can be diagnosed incorrectly. This is partly because conditions like cancer can mimic the symptoms of different diseases. It is particularly common during initial visits to the GP when symptoms are in their early stages and difficult to classify. Conditions commonly misdiagnosed can include but are not limited to:

Examples of Misdiagnosis Cases

Medical Negligence solicitor, Rebecca Dawson, recently settled a serious degenerative spinal injury misdiagnosis case. The client, who suffered many years of incontinence and leg spasms, was told by his local NHS Trust that his symptoms were inconclusive, and that he wouldn’t be given an MRI because the neurologist believed he had restless leg syndrome. Without the persistence of Rebecca and her team, the client would now be entirely wheelchair dependent. Despite the Trust failing to admit negligence, overwhelming medical evidence seen at a hearing meant that over £1 million was awarded, as part of a misdiagnosis compensation package. In January 2008, another client was diagnosed with progressive transformation of germinal centres (“PTGC”). On second viewing, there had been a negligent failure to correctly diagnose and treat our client, causing injury and loss. Treatment was not given in 2008, and the disease transformed into an aggressive B-cell Non-Hodgkin’s Lymphoma.

“If our client had been correctly diagnosed with nodular lymphocyte predominant Hodgkin’s lymphoma in 2008, he would have been treated with involved field radiotherapy, possibly with the addition of two cycles of chemotherapy.” Patient Claim Line’s Daniel Finney

  • If the victim of medical misdiagnosis has died, their family has three years from the date of death to pursue a claim on their behalf

    Robert's Story

    "You couldn’t ask for a better team"

    After his symptoms were misdiagnosed, Robert suffered a stroke affecting the left side of his body. He was in hospital for five weeks and had to attend physiotherapy for six months as part of his recovery.

    Our team secured a substantial compensation, which took into consideration the physical and mental impact of Robert’s misdiagnosis on him and his family.

    This enabled Robert’s wife to give up work as well as buy a bungalow together, making it easier for Robert, with his mobility problems. Robert is looking forward to going back to the music concerts and car shows he used to enjoy, as well as spending more time with family.
