A surgical error claim arises when avoidable harm happens during or after an operation because the care fell below the standard expected of a competent surgeon or surgical team. Surgery carries real risk even when it is done well, and a recognised complication that occurs despite careful treatment is not negligence.
To bring a claim you generally have to show three things: that the care fell below the standard of a competent practitioner in that specialty, that you suffered harm, and that the substandard care caused or materially contributed to that harm. Adults in Victoria generally have three years from the date the claim becomes discoverable, with a twelve-year long-stop.
The hardest question is usually not whether something went wrong. It is whether what went wrong was an avoidable error or an accepted risk of the procedure. That distinction is decided on the operation notes, the consent record and independent expert opinion.
| Question to ask | Points toward an avoidable error | Points toward an inherent risk |
|---|---|---|
| Was the risk discussed beforehand? | Never raised with you, or absent from the consent record | Disclosed and documented before you agreed to the operation |
| Is this outcome expected for the procedure? | Not a recognised complication of this operation | A known complication with a documented rate |
| How was it handled afterwards? | Not noticed, or noticed and not acted on | Identified promptly and managed appropriately |
A guide to what the evidence tends to show. Only an independent expert review of your records can answer it for your case.
What do you have to prove?
- Below-standard care. The surgeon, anaesthetist or another member of the team provided care that fell below what a competent practitioner in that specialty would have provided in the same circumstances.
- Harm. You suffered an injury or adverse outcome as a result — not merely the known risk of the procedure, but harm that was avoidable.
- Causation. The substandard care caused or materially contributed to the harm. Where a complication can have several causes, expert evidence is usually needed to draw that connection.
These are the same elements that apply to every medical negligence claim. They are set out in more detail in How to establish a medical negligence claim.
What are the most common surgical errors?
- Operating on the wrong site, the wrong side, or the wrong patient
- Injury to adjacent organs, nerves or blood vessels that a competent surgeon would have avoided
- Instruments or swabs left inside the body after an operation
- Anaesthetic errors, including the wrong dose, a failure to monitor, or an allergy that was not identified
- Consent taken without warning you of a material risk
- Post-operative monitoring that missed a complication which then worsened
Some of these are what Safer Care Victoria classifies as sentinel events, meaning incidents serious enough that a health service must report and review them. A sentinel event report is not proof of negligence, but it does mean the service has already examined what happened.
How long do you have to bring a claim?
Adults generally have three years from the date the claim becomes discoverable. That can be later than the operation itself, because the harm may only become apparent over time. A twelve-year long-stop also applies, and different rules cover children and people under a disability.
The rules are technical and the dates are not always obvious, so it is worth checking early rather than assuming. See Time limits for medical negligence claims for the full position.
What compensation can you claim?
- The cost of corrective surgery or further treatment needed because of the error
- Rehabilitation and ongoing therapy
- Care and support, including unpaid care provided by family
- Past and future lost income where the injury has affected your ability to work
- Pain and suffering, where the injury meets the threshold set by the Wrongs Act 1958 (Vic)
No figure can be quoted from a website, because compensation depends on your own losses. What compensation can you recover explains how each category is worked out.
How Clever handles surgical error claims
These claims turn on documents: operation notes, anaesthetic records, post-operative observations, and an independent opinion from a surgeon in the relevant specialty. Organising that material is the expensive part, and it is the reason some claims are turned away before anyone looks closely.
Our technology does the organising. Our lawyers review the evidence and make every legal decision. If the evidence supports a claim, we act on no win, no fee, fixed for each stage of work, capped at 20% of what you recover. If it does not, you are told plainly why.
Common questions
Is a bad surgical outcome always negligence?
No. Every operation carries risk, and a poor result on its own does not establish a claim. What matters is whether the care fell below the standard of a competent surgeon, and whether that failure caused the harm. A recognised complication that was properly disclosed, competently managed and promptly treated is generally not negligence, even where the outcome is severe.
Does signing a consent form stop you making a claim?
No. Consent covers the risks that were actually explained to you, and it is consent to the procedure being performed competently. It is not agreement that the operation can be performed carelessly. If a material risk was never disclosed, or if the harm came from a mistake rather than a disclosed risk, a signed consent form does not prevent a claim.
Do you need your operation notes before getting advice?
No. You can start without them. You have a right to your own records, and they can be requested as part of investigating the claim. If you would rather collect them yourself first, How to get your medical records in Victoria sets out who to ask and what it costs.
What if the surgery was done in a public hospital?
A claim can still be brought. The defendant is usually the health service rather than the individual surgeon, because a public hospital is generally responsible for the care its staff provide. The elements you have to prove are the same either way.
