Surgical Site Infection Claims in Ireland
Answer in brief: You may be able to make a medical negligence claim for a surgical site infection in Ireland. A claim is possible only where the infection resulted from a failure in sterile technique, theatre or instrument hygiene, antibiotic prophylaxis, or post-operative wound care that fell below the accepted standard and caused your harm. A wound infection after surgery isn't, on its own, proof of negligence. This is a personal injury claim that proceeds in court, not through the Injuries Resolution Board (IRB).

What is a surgical site infection?
A surgical site infection is an infection that develops in the part of the body where an operation took place. Clinically, it is usually defined as an infection arising within 30 days of surgery. Where an implant such as a joint replacement or internal fixation device was used, that window extends to 90 days HPSC, Prevention of Surgical Site Infections (Updated December 2024)[1].
Infections are graded by how deep they reach. A superficial incisional infection affects the skin and the tissue just beneath it. A deep incisional infection reaches the muscle and the surrounding fascia. An organ or space infection affects an internal organ or a body cavity that was opened during the procedure World Health Organization, Global Guidelines for the Prevention of Surgical Site Infection (Updated 2018)[2]. Surgical site infections are among the most common healthcare-associated infections recorded in Irish hospitals HPSC, Point Prevalence Survey 2023 National Report (Updated November 2024)[3].
Speed of recognition matters, and it's worth knowing the early signs. An infection caught early can often be treated with antibiotics, while one left to advance can spread to deeper tissue or, in serious cases, trigger sepsis from a hospital infection. This page deals with infections linked to the surgical procedure itself. For infections that arise elsewhere in a hospital stay, see our hospital-acquired infection claims hub.
What are the signs of a surgical site infection?
The early signs of a surgical site infection are worth knowing, because acting quickly can prevent a minor infection becoming a serious one. The HSE advises patients to watch for the signs below after surgery and to contact a doctor straight away if they appear HSE, Recognising Surgical Site Infection at Home (Updated 2023)[4].
| Possible sign of infection | What to do |
|---|---|
| A fever, with a temperature above 38°C, or chills and flu-like symptoms | Contact your GP straight away. If it is out of hours, contact the local out-of-hours doctor. Do not wait to see if it settles. |
| Redness, swelling, increasing pain, bleeding, an unpleasant smell, or any discharge from the wound | |
| Pain that does not improve with your usual pain relief | |
| Nausea or vomiting that does not improve |
Some redness, swelling and discomfort is normal in the first days of healing, so these signs do not always mean an infection. A surgical site infection most often appears within 30 days of surgery, or within 90 days where an implant was used, and the table below sets out the timing and depth that doctors record.
| Feature | Detail |
|---|---|
| When it appears | Usually within 30 days of surgery, or within 90 days where an implant such as a joint replacement was used |
| Depth | Superficial incisional (skin), deep incisional (muscle and fascia), or organ or space (an internal organ or cavity) |
| Source of bacteria | Endogenous (from the patient's own body) or exogenous (from outside, such as instruments, the surgical field, or staff) |
| How common in Ireland | In 2022, almost 3,000 patients in Ireland were recorded with a wound infection or wound opening after general surgery, with an average hospital stay of 24 days HSE (Updated 2023)[4] |
Recognising an infection is the first step. The separate question this page answers is a legal one: where a surgical site infection was caused by care that fell below the accepted standard, you may be able to pursue compensation for the injury in Ireland.
When is a surgical site infection negligence in Ireland?
An infection on its own isn't ever enough to bring a claim. Surgery carries an inherent risk of infection even when every protocol's followed correctly. A claim exists only where care fell below the accepted standard and that failure caused, or materially contributed to, the infection or the harm that followed.
The standard of care in an Irish medical negligence claim is assessed under the principles in Dunne v National Maternity Hospital [1989], which the Supreme Court unanimously reaffirmed in Morrissey v HSE [2020] as the test that applies in Ireland as explained in our guide to breach of duty and the Dunne principles. In short, a hospital or surgeon is negligent where the care given deviated from general and approved practice in a way that no reasonably competent practitioner would have followed. A failure to follow a clinical guideline is not, by itself, proof of negligence, and following one is not, by itself, a defence. This is the Irish test. It isn't the same as the Bolam and Bolitho test used in the United Kingdom, so UK guidance on surgical negligence does not state the standard that applies here. The broader legal framework that applies to every hospital infection is set out on our page about infection-control failures. This page applies that test to the surgical pathway.
In a surgical setting, a breach usually sits at one of four points. These track the safety checks the operating team is expected to follow under the HSE National Policy and Procedure for Safe Surgery, which adopts the World Health Organization Surgical Safety Checklist and its Sign In, Time Out and Sign Out steps HSE, National Policy and Procedure for Safe Surgery (Updated 2022)[5].
| Phase | What should happen | Examples of a possible breach |
|---|---|---|
| Before surgery | Screening for resistant organisms where indicated for the procedure, and proper skin preparation | Failure to screen or decolonise a known carrier before an operation that called for it, or inadequate skin preparation |
| During surgery | A sterile surgical field, properly sterilised instruments, and antibiotic prophylaxis given within the recommended window | Breach of the sterile field, use of inadequately sterilised instruments, or prophylactic antibiotics given outside the recommended window before incision |
| After surgery | Sterile wound closure, clear wound assessment, and a response to early signs of infection | Failure to assess the wound, to document observations, or to act on clear early signs of infection before discharge |
The value of these phases for a claim is that each one is meant to be recorded. The Sign In confirms preparation before anaesthesia. The Time Out, the final pause before incision, includes confirming infection-prevention measures and that any antibiotic has been given. The Sign Out, before the team leaves theatre, confirms the procedure is complete and counts are correct HSE, Surgical Safety Checklist (Updated 2022)[6]. Where a step that should have protected against infection was skipped or not documented, that gap in the record is often the starting point for an expert review.
National guidance on prophylactic antibiotics is one area where records frequently matter. An Irish point-prevalence survey found that a large share of surgical antibiotic prophylaxis exceeded the single dose recommended for most procedures, which is the kind of documented pattern an expert may examine HSE, Framework for the National Programme for Surgical Site Infection Surveillance (Updated 2023)[7]. The national standards a hospital is expected to meet are published by HIQA HIQA, National Standards for the Prevention and Control of Healthcare-Associated Infections (Updated 2017)[8].
Infection-control failure or surgical error? The two are different claims. An infection from external contamination during surgery, such as an unsterile instrument or a broken sterile field, is an infection-control failure, and it belongs on this page. An infection caused by a surgical mistake, such as a perforation of the bowel that releases internal bacteria, is a surgical error. Where the infection followed a technical error in the operation, see our guide to surgical errors. Knowing whether a wound infection was a recognised risk or the result of negligence is the first step in deciding whether you can pursue compensation for the injury in Ireland.
One defence point is worth understanding early. A hospital will often say it's followed its infection-control policy. What matters isn't whether a policy existed on paper, but whether it was actually followed for your operation. That's why the contemporaneous records, rather than the policy document, tend to decide these cases.
Recognised complication or negligence? A practical guide
Many people who contact us were told that infections simply happen, and they're unsure whether that means nothing can be done. Common does not mean non-negligent. The table below can't decide your case, but it shows how the same situation can fall on either side of the line.
| Situation | More like a recognised complication | More like possible negligence |
|---|---|---|
| Deep wound infection | Infection develops despite correct sterile preparation and prophylactic antibiotics given on time | Surgery performed with inadequately sterilised instruments, or required antibiotics not given |
| Wound that opens after surgery | The wound opens due to unavoidable healing failure or patient exertion | Staff ignore days of discharge, redness and a rising temperature before the wound breaks down |
| Infection after discharge | Clear wound-care instructions were given and early review was arranged | The patient was discharged with obvious early signs of infection that were not acted on |
If several of your circumstances fall into the right-hand column, it is worth having the records reviewed by an expert. Only a qualified expert, with full access to your file, can say whether the Irish legal tests for negligence are likely to be met. If you're unsure, it's worth asking.
A short illustration of how this plays out: a patient is discharged a few days after routine surgery with a wound that is mildly red. Over the next week the redness spreads, the wound begins to leak, and a temperature develops. The patient returns to hospital, where the wound is found to be infected and has partly opened. Whether this supports a claim depends entirely on the records: if early signs were noted before discharge and not acted on, that may be a breach. If the wound looked normal at discharge and the infection developed later despite proper care, it may simply be a recognised risk. This is a general example, not a case study, and only an expert review of the actual file can tell the two apart.
Proving a surgical site infection claim: evidence and causation
A claim rests on two pillars. The first is breach: showing that the care fell below the accepted standard. The second is causation: showing that the breach, rather than chance or the patient's own risk factors, caused the infection or the harm that followed.
Causation is usually the harder of the two in infection cases, and the reason is the source of the bacteria. An infection can be endogenous, meaning it came from the patient's own skin or body, or exogenous, meaning it came from outside, such as contaminated instruments, an unsterile field, or organisms shed by theatre staff World Health Organization, Global Guidelines for the Prevention of Surgical Site Infection (Updated 2018)[2]. Exogenous infection is the pattern most often linked to an infection-control breach, because it points to contamination that proper practice should have prevented. Since a patient's own flora, community organisms and hospital organisms can all coexist, proving the source to a strict standard is difficult. Where the strict "but for" test cannot be met, Irish law may allow causation to be shown through the material contribution test, where the breach materially increased the risk of the infection. The doctrine itself is explained on our causation page.
Because the science is technical, expert evidence is central. These cases typically need a consultant surgeon to address the standard of care and a microbiologist or infectious-diseases expert to address causation and preventability. In Irish medical negligence claims the expert is often based outside the State to ensure independence. Our pages on expert witnesses and the expert medical report explain how this works.
The records below are often decisive, and you have a right to request your file.
| Record | Why it matters |
|---|---|
| Operative and anaesthetic notes | Show what happened in theatre, including the timing of any prophylactic antibiotics |
| Pre-operative screening records | Show whether screening was carried out where indicated, and what action followed |
| Wound-care charts and observations | Show whether the wound was assessed and whether early signs were acted on |
| Wound swab and culture results | Identify the organism and can help with the question of source |
| Infection-control and audit records | Can reveal compliance levels for the relevant theatre and period |
You can request your records directly from the hospital. Under data protection law, an access request generally must be answered within one month Data Protection Commission, Right of Access (Updated 2023)[9]. The Patient Safety (Notifiable Incidents and Open Disclosure) Act 2023, commenced on 26 September 2024, requires hospitals to disclose a defined list of serious notifiable incidents to patients or their families. Most serve where a patient dies or suffers serious harm, so a routine wound infection is not usually a notifiable incident, although the wider duty of candour still applies Citizens Information, Patient Safety (Updated 2024)[10].

What the hospital may argue, and what an expert examines
In infection cases the defence tends to raise the same points. Knowing them early helps explain why the records matter so much. None of these arguments ends a claim on its own.
| What the hospital may say | What an independent expert examines |
|---|---|
| "Infection is a known risk of surgery." | Whether the infection followed a specific breach of sterile technique, hygiene, prophylaxis or wound care, rather than occurring despite correct care. |
| "The patient's own risk factors caused it." | Whether the breach materially increased the risk, applying the material contribution test, even where the patient had risk factors such as diabetes. |
| "We followed our infection-control policy." | The contemporaneous records for the actual operation, since ward-level and time-specific data can differ from a hospital's headline compliance figures. |
Effects and long-term consequences
The consequences of a surgical site infection range widely. A superficial infection may delay recovery by a few weeks and resolve with antibiotics. A deeper infection can lead to wound breakdown, repeated cleaning operations, a longer hospital stay, and readmission.
In more serious cases, an infection can cause lasting harm, including chronic bone infection, permanent scarring, or the need for revision surgery. Where an untreated infection spreads, it can progress to sepsis from a hospital infection, which can be life-changing. The physical effects are often accompanied by psychological harm and by financial loss where the person cannot return to work. The way these injuries are classified for a claim is covered on our page about injuries caused by medical negligence.
Compensation for a surgical site infection claim
There's no single compensation figure for a surgical site infection, because the value of a claim depends on the consequences rather than the infection label. Compensation is assessed by reference to the Judicial Council's Personal Injuries Guidelines, which set out ranges based on the nature and severity of the injury and its effect on the person Judicial Council, Personal Injuries Guidelines (Updated 2021)[11]. Awards vary case by case.
A claim is usually made up of two parts. General damages reflect pain, suffering and the effect on quality of life. Special damages reflect financial losses that can be proven, such as the cost of further surgery and care, and past and future loss of earnings. Where an infection causes severe or permanent harm, the financial element can become the larger part of a claim. For how these figures are approached, see our pages on medical negligence compensation and injuries.
Time limits and the date of knowledge
The general rule is that you have two years to bring a medical negligence claim. That's a shorter window than the three years that applies in the United Kingdom, which is one reason UK timelines should not be relied on for an Irish claim. For an infection, the clock does not always start on the day of surgery. It usually starts on the date of knowledge, which is when you first knew, or reasonably should have known, that you had a significant injury and that it was connected to your care. The two-year period itself is set by section 7 of the Civil Liability and Courts Act 2004, which reduced the previous three-year period with effect from 31 March 2005, while the date-of-knowledge test is supplied by the Statute of Limitations (Amendment) Act 1991 Civil Liability and Courts Act 2004, s.7[12].
This matters in infection cases because symptoms can appear weeks after an operation, and the realisation that standards may not have been met often comes only after an expert reviews the records. Different rules apply for children and where a person's died. The full detail is on our page about time limits for hospital infection claims. Missing the deadline can remove your right to pursue compensation for the injury, regardless of how strong the claim is, so early advice is important.
What to do if you think your wound is infected
If you think your surgical wound may be infected, the steps below put your health first and also protect your position if a claim later turns out to be possible.
- Get medical attention first. Contact your GP straight away, or the out-of-hours doctor, or attend an emergency department if you are very unwell. Treating the infection matters more than anything else.
- Keep a simple record. Note the dates your symptoms started, take photographs of the wound, and keep any letters, prescriptions and appointment details.
- Request your medical records. You can ask the hospital for your file, including the operative notes and wound-care charts. Under data protection law the request is generally answered within one month.
- Get legal advice if you have concerns. If you believe the infection may have been preventable, a solicitor can arrange an independent expert review. The cost of pursuing a claim, and funding options, are explained on our no win, no fee and legal costs pages.
Seeking medical care or asking for your records does not commit you to a claim. It simply keeps your options open while you decide.
How a claim works and how we can help
Clinical negligence is a substantial part of claims against the State. The State Claims Agency reported that the outstanding liability it manages stood at roughly 5.35 billion euro, of which clinical negligence claims made up about 81 per cent State Claims Agency, NTMA Annual Report 2024 (published 2025)[13]. Medical negligence claims in Ireland, including surgical site infection claims, do not go through the Injuries Resolution Board (IRB), formerly the Personal Injuries Assessment Board (PIAB) until 2023. Because of the complexity of medical causation, these claims proceed directly in court and require an independent expert report from the outset.
In practice, a claim usually follows a clear sequence. Your solicitor requests and reviews the full medical file, instructs an independent expert to report on breach and causation, and, where the report is supportive, issues a letter of claim. The hospital responds, and most cases are then resolved by negotiation, with court proceedings issued where needed. Our medical negligence process page sets out each stage.
Early advice helps because evidence can be lost over time and the limitation clock has its own quirks. You don't have to work this out alone. As personal injury solicitors in Dublin, we act for clients across Ireland.

Common questions
Is a wound infection after surgery automatically negligence?
No. A surgical site infection is a recognised risk of surgery and can occur even with correct care. It may support a claim only where a standard-of-care failure caused or materially contributed to the infection or the resulting harm.
Why it matters: The distinction between a recognised risk and a negligent failure decides whether a claim is possible.
Next step: How infection-control negligence is proven · The Dunne standard
What if my wound infection was not treated quickly enough?
A delay in recognising or treating an established infection can be a basis for a claim where it caused avoidable harm. The records of your post-operative observations and wound care are usually central to showing whether early signs were acted on.
Why it matters: Delayed treatment is one of the more common patterns behind a viable claim.
Next step: Causation in medical negligence · Injuries and consequences
How do you prove a surgical infection was the hospital's fault?
You need to show both a breach of the accepted standard and causation. Expert evidence from a consultant surgeon and a microbiologist is usually required, supported by theatre notes, antibiotic timing records, wound-care charts and culture results.
Why it matters: Causation is technically complex, so the quality of the records and expert evidence is decisive.
Next step: Expert witnesses · The expert medical report
Does a surgical infection claim go through the Injuries Board?
No. Medical negligence claims, including surgical site infection claims, are outside the remit of the Injuries Resolution Board and proceed directly in court. An independent expert report is needed from the outset.
Why it matters: The process differs from a standard personal injury claim, which starts at the IRB.
Next step: The medical negligence process
What is a surgical site infection claim worth?
There's no fixed figure. Compensation depends on the consequences, such as further surgery, scarring, prolonged recovery or lost earnings, and is assessed under the Personal Injuries Guidelines. Awards vary case by case.
Why it matters: Value follows the harm caused, not the infection label.
Next step: Medical negligence compensation · Time limits
How long after surgery can a surgical site infection appear?
Most surgical site infections appear within 30 days of the operation. Where an implant such as a joint replacement was used, the recognised window extends to 90 days. Signs include increasing pain, redness, swelling, heat, or fluid leaking from the wound, sometimes with a fever.
Why it matters: The timing affects the date of knowledge, which can decide your deadline to claim.
Next step: Time limits · Date of knowledge
What records should I request from the hospital?
Ask for your full file, including the operative and anaesthetic notes, any pre-operative screening records, wound-care charts and observations, wound swab and culture results, and discharge summary. Under data protection law, the hospital generally must respond within one month.
Why it matters: These records, not the policy document, usually decide whether a breach can be shown.
Next step: Right of access (DPC) · The claims process
Does the hospital have to tell me if there was an infection-control breach?
Sometimes. Under the Patient Safety Act 2023, hospitals must formally disclose a defined list of serious notifiable incidents, most of which involve death or serious harm, so a routine infection is often outside that list. The wider duty of candour still applies. An apology given at open disclosure isn't an admission of liability, and disclosure doesn't replace an independent expert review of your records.
Why it matters: Disclosure can flag a problem, but proving negligence still needs the records and expert evidence.
Next step: Patient safety (Citizens Information) · Infection-control failures
Can I claim if my operation was in a private hospital?
Yes. A claim can be brought whether your surgery was in a public or a private hospital, because the duty to meet the accepted standard of infection prevention and control applies in both. Who the claim is brought against, and how it is defended, can differ between the two settings.
Why it matters: The setting changes the procedure, not your right to pursue a claim. It's the standard of care that matters.
