Sepsis Misdiagnosis Claims in Ireland: Proving a Breach of HSE Guideline No. 26

This is general information about sepsis misdiagnosis claims in Ireland, not legal advice. Every case depends on its specific facts. Consult a solicitor for advice on your situation.

What should you do right now if you suspect sepsis was missed?

If you believe sepsis was missed or delayed in your care, or in a family member's care, take these steps as soon as possible.

1. Write down dates and names. Record the dates of every hospital visit, the names of treating doctors and nurses you remember, and what you were told about your condition at each stage.
2. Request your medical records. Submit a data subject access request (DSAR) to the hospital or GP practice. Ask specifically for nursing observation charts, blood results (including lactate), antibiotic administration records, discharge summaries, and A&E triage notes.
3. Do not discuss your case on social media. Posts about your treatment can be used by a defendant's legal team. Keep details private.
4. Contact a medical negligence solicitor. Do not wait to see if symptoms improve. The two-year limitation clock under the Statute of Limitations (Amendment) Act 1991 ⁴ may already be running, and records and recollections fade over time.

What counts as a sepsis misdiagnosis under Irish law?

A sepsis misdiagnosis claim requires proof that a healthcare professional's failure to recognise or treat sepsis fell below the standard of a reasonably competent practitioner in Ireland. Irish courts apply the test from Dunne v National Maternity Hospital [1989] IR 91: if a doctor's conduct would not be approved by a responsible body of medical opinion, it amounts to a breach of duty. Unlike in England and Wales, where courts use the Bolam/Bolitho test, Irish law applies the Dunne principles, and the two-year limitation period is shorter than the three-year UK equivalent. For sepsis, the clinical standard is not subjective. It is codified in HSE National Clinical Guideline No. 26 ¹, which defines exactly how hospitals must recognise, escalate, and treat the condition.

A detail that catches many claimants off guard: developing sepsis during a hospital stay is not automatically negligence. The negligence lies in the response to it. If staff failed to recognise deterioration, delayed treatment, or did not follow the Sepsis-6 protocol, that is the breach. The distinction matters because defence teams representing the HSE will argue the outcome was inevitable. We call this the Sepsis-6 Record Audit, the process of working through the medical file step by step against each element of the protocol to identify exactly where the standard was not met.

What is the Sepsis-6 bundle?

The Sepsis-6 bundle requires six clinical interventions to be started within one hour of recognising sepsis in Ireland. Under HSE clinical guidelines [5], the six steps fall into two groups of three.

The clock starts at "Time Zero," the point when a patient's Early Warning Score triggers a sepsis screen. In Irish hospitals, these scores are the Irish National Early Warning System (INEWS) for adults, the Irish Maternity Early Warning System (IMEWS) for pregnant and postpartum patients, and the Paediatric Early Warning System (PEWS) for children. A hospital's failure to calculate the Early Warning Score at all means Time Zero is never recorded. That failure is itself a breach, separate from any later delay in treatment. Nursing observation charts should show regular clinical observations recorded at set intervals. Gaps in those charts are often the first piece of evidence a solicitor reviews during a Sepsis-6 Record Audit.

What changed in the 2025 update to Guideline No. 26?

The HSE published a rapid update to NCG No. 26 in 2025, changing how antibiotic timing is applied based on illness severity at presentation. According to the HSE announcement (2025) ², the update moved away from a blanket one-hour antibiotic rule to a stratified approach.

The timing distinction is significant in practice: a solicitor reviewing your records must determine which flag category applied to your presentation and whether the corresponding timeframe was met. Because this 2025 update changed the standard, it directly affects what constitutes a breach for any case arising after the guideline was revised.

Why does causation decide whether a sepsis claim succeeds?

Proving breach in a sepsis claim is often straightforward because the protocol steps are documented in clinical records. Proving causation is the harder part. You must show that earlier treatment, on the balance of probabilities, would have produced a materially better outcome in your case. Defence teams almost always argue the same point: that the patient's deterioration was inevitable regardless of the care provided.

Defeating this defence in Irish courts requires a specialist independent medical expert, typically a consultant intensivist or clinical microbiologist, who can reconstruct the clinical timeline. The expert must address three questions: what the specific pathogen was, when the window of effective treatment closed, and whether completing the Sepsis-6 bundle within the required timeframe would have changed the trajectory. Serum lactate levels are often the single most telling piece of evidence in this analysis. Elevated lactate indicates tissue hypoperfusion, meaning organs are not receiving enough blood flow. If the records show elevated lactate and a delay before antibiotics were given, the expert can construct a forensic timeline showing the gap between when treatment was needed and when it arrived. Between assessment and settlement, the sticking point is usually this causation argument. From handling sepsis claims through the Irish courts, the strength of the expert report on causation determines whether the case settles or proceeds to hearing. The next step is to instruct a solicitor experienced in Irish medical negligence claims who can identify the right expert for your specific infection.

Where does sepsis get missed in Irish hospitals and GP practices?

Sepsis misdiagnosis in Ireland most commonly occurs in three clinical settings: emergency departments, GP practices, and post-surgical wards. Each setting presents different failure patterns. The underlying infections that most frequently lead to sepsis claims include urinary tract infections (UTIs), pneumonia, appendicitis, cellulitis, gallbladder infections, peritonitis, post-surgical wound infections, and meningitis. In each case, the legal question is the same: did the treating clinician recognise that the infection was progressing toward sepsis and act within the timeframes required by NCG No. 26?

Emergency departments: Early sepsis often mimics common infections such as flu, urinary tract infections, or gastroenteritis. Triage staff may assign a low priority score. If an INEWS screen is not conducted at presentation, the clinical clock never starts. One detail that surprises clients: the nursing observation charts in their medical records often show rising heart rate and falling blood pressure for hours before any medical review was requested.

GP practices: A GP who sees a patient with an established infection and worsening symptoms has a duty to consider sepsis as a differential diagnosis under Irish clinical standards. The HSE launched a dedicated GP update on adult sepsis in primary care in October 2024. Failing to refer an amber-flag patient to an emergency department within a clinically appropriate timeframe may amount to a breach. Families sometimes discover this failure only after a premature discharge leads to rapid deterioration at home.

Post-surgical settings: Wound infections following surgery can progress to sepsis if prophylactic antibiotics are omitted or if post-operative observation does not include regular Early Warning Score assessments. Surgical patients with a sepsis diagnosis spend an average of 46.4 days in hospital, compared to 5 days for surgical patients without sepsis, according to the National Sepsis Report ³.

Children and neonates: Sepsis in children can progress faster than in adults and presents with different symptoms. Irish hospitals use the Paediatric Early Warning System (PEWS), which has different escalation thresholds than the adult INEWS. Children under five and neonates are at higher risk. HSE National Sepsis Reports show that paediatric in-hospital mortality from sepsis is significantly lower than adult rates but still represents preventable deaths when the PEWS protocol is not followed. Parents who suspect sepsis was missed in their child's care should request the PEWS observation charts specifically. Maternal sepsis, including infections arising during labour or in the post-partum period, is assessed using the Irish Maternity Early Warning System (IMEWS) and is addressed in detail on our maternity negligence page.

Can you claim for post-sepsis syndrome in Ireland?

Yes. Post-sepsis syndrome (PSS) affects up to 50% of sepsis survivors and can last months or years after the initial infection. According to research published in the European Journal of Internal Medicine (2023) [6], PSS involves a combination of physical, cognitive, and psychological effects that significantly reduce quality of life and ability to work.

PSS is routinely under-claimed because neither the claimant nor their previous solicitor recognised these symptoms as sepsis-related and compensable under Irish law. The Guidelines state indicative ranges for general damages, but in practice, the value of a PSS claim depends on documenting the full spectrum of effects through rehabilitation medicine and neuropsychology reports. These reports directly affect the value of both general and special damages under the Personal Injuries Guidelines (2021) [7]. At this point, you'll need to decide whether to accept an early settlement offer or build the full PSS evidence file first.

What are the most common misconceptions about sepsis claims in Ireland?

Three common assumptions about sepsis claims in Ireland are either outdated or incorrect under current Irish law and clinical standards.

1. "Sepsis claims go through the Injuries Resolution Board." They do not. Medical negligence claims in Ireland are exempt from the IRB process ⁴. You do NOT need to apply to the IRB before issuing proceedings. Your solicitor files directly in the High Court or Circuit Court.

2. "The one-hour antibiotic rule applies to every patient." Not since the 2025 update. Under the revised NCG No. 26 ², antibiotic timing is now stratified by clinical severity. Red-flag patients have a one-hour window. Amber-flag patients have a three-hour review window. If your case involves an amber-flag presentation, the relevant standard is the three-hour review, not the one-hour rule.

3. "NICE guidelines set the standard for sepsis care in Ireland." NICE guidelines apply in England and Wales. Ireland has its own clinical standard: HSE National Clinical Guideline No. 26 ¹. Unlike in England and Wales, where the Bolam test applies, Irish medical negligence law follows the Dunne principles from Dunne v National Maternity Hospital [1989]. The legal test, the clinical guideline, and the limitation period are all different. You CAN bring a sepsis claim in Ireland even if a UK-focused guide suggests the process or timeline differs.

How does the Patient Safety Act 2023 affect sepsis cases?

The Patient Safety (Notifiable Incidents and Open Disclosure) Act 2023 [8] came into effect on 26 September 2024 and requires mandatory disclosure of serious patient safety incidents in Ireland. Under this Act, healthcare providers must inform patients and families when a notifiable incident occurs. Schedule 1 includes deaths related to medical treatment and other serious harm events.

The Department of Health (2024) [9] confirmed this legislation embeds transparency, not new litigation risks for providers. For families, it means you should receive disclosure without having to request it.

How common is sepsis in Ireland?

In 2023, 14,535 non-maternity adults were diagnosed with sepsis or septic shock in Irish hospitals, with a mortality rate of 20.6% and an average hospital stay of 22 days. These figures come from the HSE National Sepsis Report 2023 ³. The HSE's National Sepsis Programme, established in 2013 following the death of Savita Halappanavar [10], has contributed to a 26.5% reduction in age-adjusted mortality since 2011.

Sepsis or infection contributes to approximately 60% of all in-hospital deaths in Ireland and accounts for 42% of all in-hospital bed usage. The HSE's Action on Sepsis: Five-Year Strategy (2025 to 2030) acknowledges that sustained improvement requires continued investment in staff training, clinical audit, and guideline compliance. For claimants, these data points serve two purposes: they show the scale of the risk, and they provide a benchmark against which your individual case can be assessed.

Who do you claim against and how does the process work?

Most sepsis negligence claims in Ireland are brought against the HSE or a hospital covered by the State Claims Agency [11] under the Clinical Indemnity Scheme. The State Claims Agency manages the claim on behalf of the HSE. Private practitioners typically carry their own medical indemnity insurance.

The process starts with your solicitor obtaining your full medical records through a data subject access request. An independent medical expert then conducts a Sepsis-6 Record Audit, reviewing each protocol step against the clinical file. If the expert confirms a breach and establishes causation, your solicitor issues a letter of claim. Unlike in England and Wales, there is no formal pre-action protocol in Ireland for clinical negligence. The next step is issuing proceedings in the High Court or Circuit Court. For detailed information on the claims process, see our guide to medical negligence claims in Ireland.

How long does a sepsis claim take in Ireland?

A sepsis negligence claim in Ireland typically takes between 2 and 4 years from first instruction to resolution, depending on complexity and whether the defendant disputes liability. Most claims against public hospitals are managed by the State Claims Agency ¹¹. The table below gives indicative ranges. Actual timelines vary case by case.

These are experience-based estimates, not guarantees. Straightforward cases where breach is clearly documented in the records can resolve faster. Cases involving disputed causation or catastrophic injuries typically take longer because multiple experts are required on both sides.

What are the time limits for a sepsis claim in Ireland?

You have two years to bring a sepsis negligence claim from the date you knew or should have known that negligence contributed to your injury. The Statute of Limitations (Amendment) Act 1991, s.2 ⁴ defines this as the "date of knowledge." For sepsis survivors, this date is not always the date of the hospital stay. Many patients only discover that sepsis was missed weeks or months later, after a second medical opinion, a review of records, or a coroner's inquest in fatal cases.

For children under 18, the two-year clock does not start until their 18th birthday. Where a patient died, dependants generally have two years from the date of death. Three common scenarios illustrate how the date of knowledge works in sepsis cases in Ireland. A patient discharged with a "viral infection" who is readmitted with septic shock 48 hours later may not realise the first discharge was negligent until reviewing the records months later. A family whose relative died in hospital may only learn sepsis was the cause from the post-mortem report. A survivor experiencing cognitive decline may not connect it to their sepsis episode until a specialist diagnoses post-sepsis syndrome. In each case, the two-year clock may start from the later discovery date, not the original hospital admission.

If you are unsure whether time has passed, seek legal advice promptly. Your solicitor can assess whether the date of knowledge extends your window. For more on how limitation works, see our date of knowledge guide.

What compensation is available for sepsis negligence in Ireland?

Compensation in a sepsis claim covers both general damages (pain, suffering, and loss of quality of life) and special damages (financial losses caused by the negligence). The Personal Injuries Guidelines (2021) ⁷ set indicative ranges for general damages based on injury severity. Each case is assessed individually. Awards vary significantly depending on the injuries sustained, the duration of recovery, and the long-term prognosis.

Special damages in sepsis cases can include past and future medical expenses, rehabilitation costs, loss of earnings (current and projected), home adaptation costs for patients with permanent disability, and care costs for those who cannot live independently. Where sepsis results in amputation, organ damage, or brain injury, the special damages component can be substantial. These specific injury outcomes are addressed on our medical negligence compensation page.

What evidence strengthens a sepsis claim?

The strongest sepsis claims in Ireland are built from medical records that show a documented pattern of deterioration that staff did not act on. A solicitor conducting a Sepsis-6 Record Audit reviews the clinical file against each step of NCG No. 26 ¹. The key evidence types are listed below.

An independent expert medical report is required in every sepsis negligence case in Ireland. The expert, usually a consultant in intensive care or infectious disease medicine, reviews the records and provides an opinion on whether the care met the standard set by NCG No. 26 and whether earlier intervention would have changed the outcome. What the timeline estimates don't account for: obtaining medical records alone can take 6 to 12 weeks, and specialist experts in sepsis may have limited availability, adding months before a claim can progress.

Which records should you request by name?

When submitting your data subject access request, ask specifically for: nursing observation charts and INEWS/IMEWS/PEWS forms, drug and medication administration records (showing when antibiotics were prescribed and when they were given), laboratory blood results (including lactate, white blood cell count, and CRP), blood culture results, A&E triage assessment notes, the discharge summary, consultant and registrar progress notes, and transfer records if you were moved between wards or hospitals. Requesting these by name typically produces a more complete file than a general "all medical records" request.
