What is a delayed diagnosis claim?
A delayed diagnosis claim arises when a doctor, hospital, GP, or other healthcare professional fails to identify a condition that a competent medical practitioner, exercising reasonable skill and care, would have diagnosed earlier.
The delay must have caused harm either by allowing the condition to worsen, by causing the patient to undergo more extensive treatment than would otherwise have been necessary, or by reducing the prospects of a full recovery.
A delayed diagnosis differs from a misdiagnosis, in which a practitioner reaches the wrong conclusion entirely, and from a failure to diagnose, where the condition is not identified at all.
In practice, all three situations may give rise to a medical negligence claim in Ireland, provided the core legal tests are met.
The legal test: What must be proved?
To succeed in a delayed diagnosis claim in Ireland, four elements must be established.
- Duty of care: The healthcare professional owed you a duty of care. This is generally established by the existence of a doctor-patient or hospital-patient relationship.
- reach of duty: The professional failed to meet the standard of care that a reasonably competent medical practitioner in the same field would have provided.
- Causation: The breach caused the harm you suffered. Under Irish law, the “but for” test applies: you must show that, but for the delay, the harm would not have occurred, or would have been less severe.
- Harm: You suffered a recognised form of harm as a result, whether physical, psychological, or financial.
Common types of delayed diagnosis claims in Ireland
Delayed diagnosis claims arise across a broad range of medical specialities. The most frequently litigated issues in Ireland include
Delayed cancer diagnosis
Cancer is the most common subject of delayed diagnosis claims in Irish courts.
A delay in diagnosing breast cancer, bowel cancer, cervical cancer, lung cancer, or prostate cancer can allow the disease to progress to a more advanced stage, significantly affecting prognosis and treatment options.
The National Cancer Registry of Ireland tracks cancer incidence and outcomes nationwide; delays in diagnosis are a recurring theme in patient safety inquiries.
Coleman Legal LLP has experience representing clients whose cancer diagnosis was delayed due to a GP’s failure to refer, misread pathology results, inadequate imaging review, or delayed follow-up after screening.
Delayed diagnosis of sepsis
Sepsis is a life-threatening reaction to infection that can lead to organ failure and death if not treated promptly. The HSE has published national sepsis management guidelines acknowledging that early recognition is critical to survival.
A failure to identify signs of sepsis in a hospital or emergency department setting, or to act on a patient’s deteriorating condition, may constitute a breach of the duty of care owed to that patient.
Delayed diagnosis of cardiac events and stroke
Delayed recognition of a heart attack, cardiac event, or stroke can result in severe and permanent disability. Prompt treatment using thrombolysis or thrombectomy is time-dependent.
Where a hospital or GP fails to carry out appropriate investigations despite symptoms, and harm results from the delay, a negligence claim may arise.
Delayed diagnosis of meningitis
Meningitis, particularly bacterial meningitis, can cause death or permanent injury within hours if not treated.
A failure to recognise the symptoms, to administer antibiotics promptly, or to refer the patient for emergency hospital assessment may give rise to a claim where the delay caused additional harm.
Delayed diagnosis of appendicitis
Appendicitis, if not diagnosed promptly, can progress to a perforated appendix, causing peritonitis and requiring significantly more complex surgery.
Where a GP or emergency department failed to carry out appropriate investigations, and the patient suffered as a result, a claim may be available.
Time Limits for making a delayed diagnosis claim
The Statute of Limitations (Amendment) Act 1991 sets the time limits within which a personal injury claim, including a medical negligence claim, must be brought in Ireland.
The general rule is that proceedings must be issued within two years of the date on which the cause of action accrued.
In medical negligence cases, the two-year period typically runs from the later of
- The date on which the injury occurred; or
- The date of knowledge, meaning the date on which the claimant first became aware, or ought reasonably to have become aware, that the injury was significant, that it was attributable to the act or omission of the defendant, and the identity of the defendant.
The date-of-knowledge rule is particularly important in delayed diagnosis cases, where a patient may not discover that a diagnosis was delayed until years after the event.
If you were only recently informed that a condition should have been diagnosed earlier, the two-year period may run from that point of discovery rather than from the original date of treatment.
Special rules apply to claims on behalf of children and individuals with disabilities.
In claims involving minors, the two-year period does not begin to run until the child reaches 18 years of age.
Families are strongly advised to seek legal advice as early as possible.
Delay in seeking advice can jeopardise your ability to pursue a claim.
How to make a delayed diagnosis claim
The process for pursuing a delayed diagnosis claim typically follows these stages.
- Initial consultation with a solicitor: Discuss the circumstances of your case, including when the diagnosis was made, what treatment you received, and the harm you believe resulted from the delay.
- Medical records: Your solicitor will obtain all relevant medical records from your GP, hospital, and any other treating clinicians. These are essential to establishing the timeline and the standard of care provided.
- Independent medical expert report: A consultant in the relevant speciality will review your records and provide an opinion on whether the standard of care fell below what was reasonably expected, and whether the delay caused your harm.
- High Court proceedings: If the claim is not settled, proceedings are issued in the High Court. The case will be managed through the court process, which includes the exchange of expert reports and, if necessary, a trial.
- Resolution: Many medical negligence cases are resolved by settlement before trial. Compensation will reflect the nature and extent of the harm suffered, including pain and suffering, loss of earnings, and the cost of future care.

Frequently Asked Questions
What is a delayed diagnosis claim in Ireland, and how do I know if I have one?
In Ireland, a delayed diagnosis claim arises where a healthcare professional failed to diagnose a condition within a timeframe that a competent practitioner would have achieved, and where that delay caused you harm.
Under the Civil Liability Act 1961, a healthcare provider owes patients a duty of care; a breach of that duty that results in harm may entitle you to compensation.
If your condition worsened, required more extensive treatment, or affected your prognosis because of a diagnostic delay, you may have a valid claim.
Coleman Legal LLP can review the circumstances of your case and advise on whether the evidence supports a medical negligence action.
How long do I have to make a delayed diagnosis claim in Ireland?
In Ireland, the general time limit for personal injury claims, including medical negligence, is two years under the Statute of Limitations (Amendment) Act 1991.
In delayed diagnosis cases, this period typically runs from the date you became aware, or ought reasonably to have become aware, that your diagnosis was delayed and that the delay caused your harm. This is known as the date of knowledge.
In claims involving children, the two-year period does not begin until the child turns 18. Seek legal advice promptly, as delay can affect your ability to bring a claim.
Does my delayed diagnosis claim have to go through PIAB?
In Ireland, medical negligence claims, including delayed diagnosis claims, are specifically excluded from the PIAB process under the Civil Liability and Courts Act 2004.
Unlike road traffic or workplace injury claims, delayed diagnosis cases proceed directly through the courts, most often before the High Court. PIAB does not assess or adjudicate on medical negligence matters.
What compensation can I claim for a delayed diagnosis in Ireland?
Compensation in a delayed diagnosis claim in Ireland is assessed on a case-by-case basis and reflects the nature and extent of the harm suffered.
It may include general damages for pain and suffering, loss of amenity, and psychological impact; special damages for financial losses, including loss of earnings and medical expenses; and the cost of future care and treatment where ongoing needs arise.
There is no fixed tariff for delayed diagnosis claims; compensation is determined by negotiation, mediation, or the court, based on the evidence and an independent medical opinion.
What conditions are most commonly the subject of delayed diagnosis claims in Ireland?
In Ireland, the most common conditions giving rise to delayed diagnosis claims include cancer (particularly breast, bowel, cervical, lung, and prostate cancer), sepsis, heart attack and cardiac events, stroke, meningitis, and appendicitis. Cancer is among the most frequently litigated delayed diagnosis conditions.
The National Cancer Registry Ireland tracks cancer incidence nationally, and delays in diagnosis are a recognised patient safety concern. Coleman Legal LLP has experience across all these conditions and works with independent consultant experts in each relevant speciality.
How is a delayed diagnosis claim proved in Ireland?
A delayed diagnosis claim in Ireland is proved through independent medical expert evidence.
A consultant in the relevant speciality reviews your medical records and provides an opinion on whether the standard of care fell below that which a competent practitioner in the same field would have provided, and whether the delay caused or contributed to your harm.
The legal test is derived from Dunne v National Maternity Hospital [1989] IESC, which established the standard of care applicable to medical negligence cases in Ireland. Your solicitor will obtain all relevant medical records and commission the necessary expert reports before proceedings are issued.
Can I make a claim against a GP for a delayed diagnosis in Ireland?
In Ireland, a general practitioner owes patients the same duty of care as any other medical professional. If your GP failed to refer you for specialist investigation, did not recognise the symptoms of a serious condition, or failed to follow up on abnormal test results, and that failure caused a delay in your diagnosis resulting in harm, you may have a claim against the GP.
Claims against GPs in private practice are typically pursued against their professional indemnity insurer. Claims against GPs under the GMS scheme may involve the HSE and the State Claims Agency.
Can I claim on behalf of a child whose diagnosis was delayed?
In Ireland, a parent or guardian may pursue a delayed diagnosis claim on behalf of a child. The Statute of Limitations (Amendment) Act 1991 provides that the two-year limitation period does not begin to run in respect of a minor’s claim until the child reaches 18 years of age.
This means that a claim arising from a delayed diagnosis in childhood can still be brought after the child has grown up. However, it is advisable to seek legal advice and gather medical records as early as possible, while evidence and recollections are fresh.
Coleman Legal LLP acts for families with children affected by delayed diagnosis across a range of conditions.
Will my delayed diagnosis claim settle out of court?
Many medical negligence claims in Ireland, including delayed diagnosis cases, are resolved by settlement before a full trial. Settlement discussions may occur at any stage of the process, including before proceedings are issued, during the exchange of expert evidence, or at mediation.
Whether and when a claim settles depends on the strength of the evidence, the nature of the harm, the defendant’s position, and the advice of your legal team.
Coleman Legal LLP will keep you fully informed at every stage and will not advise you to accept any settlement that does not properly reflect the harm you have suffered.
How long does a delayed diagnosis claim take in Ireland?
The duration of a delayed diagnosis claim in Ireland varies depending on the complexity of the case, the availability of medical experts, and whether the case is resolved by settlement or proceeds to trial.
Cases that settle before proceedings are issued can be resolved within 12 to 24 months of initial instruction. Cases that proceed through the High Court typically take longer, depending on court listing and case management requirements.
Your solicitor will provide you with a realistic assessment of the likely timeline at the outset and will update you as the case progresses.
