Informed Consent Failures and Medical Malpractice

An informed consent claim is unusual: the treatment may have been performed perfectly. The allegation is not that the provider was careless in the procedure, but that the patient was never given what they needed to decide whether to have it.

That makes these claims genuinely different from most malpractice cases, and it makes the signed form far less decisive than people assume. This article explains how they work. It is one part of a larger topic; for the full picture, see our guide to medical malpractice in Delaware.

What is informed consent?

Informed consent is the patient’s agreement to treatment, given after a provider has explained the nature of the procedure, its material risks, the reasonable alternatives, and the likely consequences of declining. It is a conversation, not a signature. A form signed without that discussion documents an event, but it does not establish that consent was informed.

The purpose is decisional autonomy: the patient, not the provider, decides what is done to their body, and that decision is only meaningful if it is made on adequate information. Delaware, like other states, treats a failure to obtain informed consent as a form of medical negligence.

When a consent failure becomes malpractice

Two things have to be established, and the second is the one most claims founder on.

The undisclosed risk was material. Not every conceivable complication has to be recited. The question is whether a reasonable patient in the same position would have considered the information significant in deciding whether to proceed. A rare but catastrophic risk — permanent paralysis, loss of a sense, death — is generally material despite being unlikely. A common but trivial one may not be.

The patient would have decided differently. The claim has to show that adequate disclosure would have changed the decision — that the patient would have declined, chosen an alternative, deferred, or sought another opinion. If they would have gone ahead regardless, the failure to disclose did not cause the harm, and there is no claim even though the disclosure was inadequate.

And the undisclosed risk has to be the one that actually materialized. A provider who failed to mention risk A is not liable because unrelated risk B occurred.

That combination is demanding. It is also why these cases turn heavily on the specific conversation — what was said, when, and in what circumstances — rather than on the paperwork.

Common examples

• Undisclosed surgical risks. A material complication that was never raised, particularly one specific to the patient’s own anatomy or condition rather than the generic list.
• Alternatives not discussed. Where a less invasive option, a different approach, or conservative management was reasonable and was never presented. Watchful waiting is an alternative, and where it is a genuine option, it should be part of the conversation.
• The procedure changed mid-operation. Something materially different from what was consented to was performed, in circumstances that did not amount to a genuine emergency.
• Consent obtained in inappropriate circumstances. After sedation had begun, moments before the procedure with no opportunity to consider, or without an interpreter for a patient who needed one.
• A different provider performed the procedure than the one the patient understood would.
• Risks specific to this patient not addressed. The generic rate is one thing; how it applies to someone with a particular condition or history is another.

Where a consent failure is established and the undisclosed risk materialized, the recoverable harm is assessed as in any malpractice case; see how damages are calculated.

What to do next

Request your complete records, including the signed consent form, any pre-operative clinic notes recording what was discussed, and the operative report. The clinic notes matter more than the form — they are where a genuine discussion, if it happened, tends to be documented.

Write down your own recollection of the conversation while it is fresh: who spoke to you, when, how long it lasted, what you were told about risks and alternatives, and what you would have done had you known. That last point is central to the claim, and a contemporaneous note of it is worth having.

Then act reasonably promptly. Delaware’s deadline runs from the date of the injury, and an affidavit of merit from a qualified medical expert must be filed with the complaint — see Delaware’s statute of limitations and the affidavit of merit.
