Informed Consent Medical Negligence Claims in Ireland

Published by Richard O'Shea, Head of Injury Department | Medical Negligence Specialist

Informed consent is a fundamental patient right and legal requirement. Before any medical procedure or treatment, doctors must explain what's involved, the material risks, and reasonable alternatives. When healthcare professionals fail to obtain proper informed consent and harm results, this constitutes medical negligence even if the procedure itself was performed perfectly.

What Is Informed Consent?

Informed consent means you understand and agree to medical treatment after receiving adequate information about it. For consent to be valid, you must have capacity (ability to understand and make decisions), receive sufficient information (about the procedure, material risks, and alternatives), and give consent voluntarily (without pressure or coercion).

Simply signing a consent form doesn't mean you gave informed consent. If the form was signed but you weren't properly informed, or if you didn't understand what you were signing, consent may not be valid.

What Information Must Doctors Provide?

Under Irish law following the Supreme Court decision in *Fitzpatrick v White* (2007), doctors must inform patients of material risks—risks that a reasonable person in the patient's position would want to know about when deciding whether to undergo treatment.

Material risks generally include common side effects (even if not serious), serious risks (even if rare), risks particularly relevant to your circumstances (e.g., risks affecting ability to work in your profession), alternative treatments available (including the option of no treatment), and likely outcomes with and without treatment.

Doctors don't need to detail every tiny risk, but they cannot withhold information about risks that would influence a reasonable person's decision.

Common Informed Consent Failures

1. Not Explaining Material Risks

The most common failure is not informing patients about significant risks. Examples include surgical risks like nerve damage, infection, or bleeding not explained, medication side effects including serious reactions not discussed, diagnostic procedure risks not disclosed (biopsy risks, angiogram complications), and permanent consequences of procedures not explained (hysterectomy ending fertility, spinal surgery potentially worsening pain).

2. Not Discussing Alternatives

Patients must know if less risky alternatives exist. This includes conservative treatment options before recommending surgery, alternative surgical approaches with different risk profiles, watchful waiting as an option for slow-growing conditions, and second opinions available before proceeding with irreversible procedures.

3. Rushing the Consent Process

Obtaining consent minutes before surgery without time to consider, using medical jargon without explaining in plain language, not allowing patients to ask questions, or providing consent forms in languages patients don't understand all constitute inadequate consent.

4. Proceeding Without Consent

Performing procedures or additional surgery without permission is inexcusable except in genuine emergencies. This includes extending surgery beyond what was consented to without emergency justification, performing hysterectomy when only consented to other gynecological procedure, or cosmetic surgeons doing additional procedures "while they're in there."

When Lack of Informed Consent Becomes Negligence

Not every consent failure creates a viable legal claim. You must prove material information was not provided (a reasonable person would have wanted to know this risk/alternative), you would not have consented if properly informed (this is subjective—what would YOU have decided?), and harm occurred that you should have been warned about (you suffered a risk that should have been disclosed).

The key test is: would a reasonable person in your circumstances have consented to the procedure if they'd been properly informed? If the answer is no, and the undisclosed risk materialized causing harm, you have grounds for a claim.

Proving Informed Consent Claims

These claims require the consent form and what it says (or doesn't say), your medical records including consultation notes about what was discussed, expert evidence on what information should have been provided for that procedure, and your own testimony about what you were told and what you would have decided if properly informed.

Doctors often claim they provided verbal information not documented in records. However, the burden is on them to prove adequate information was given. Courts recognize that patients cannot be expected to remember detailed medical discussions months or years later, while doctors should document consent discussions in records.

Compensation for Lack of Informed Consent

Informed consent claims can be challenging to value because they involve a "loss of autonomy"—the right to make your own informed decision about your body. If you would have declined the procedure and avoided the harm, compensation covers all injuries suffered from the unauthorized treatment just as if the procedure itself was negligent.

If you would ultimately have consented but wanted more time to consider or prepare, compensation may be more limited, reflecting the distress of undergoing treatment without full understanding and any additional harm from lack of preparation.

Special Situations

Emergencies

In genuine medical emergencies where delay to obtain consent would cause serious harm and the patient cannot consent (unconscious, lacks capacity), doctors can proceed without consent. However, the emergency must be real—"we have theatre time available now" is not an emergency justifying bypassing informed consent.

Patients Lacking Capacity

For patients who lack capacity to consent (severe intellectual disability, advanced dementia, unconscious), consent must be obtained from next of kin or legal guardian. Treatment must be in the patient's best interests.

Children

Parents or guardians provide consent for children under 18. However, mature minors (typically 16-17-year-olds) who understand the treatment may give valid consent. Doctors should involve children in discussions appropriate to their age and understanding.
