In Rogers v Whitaker (1992), the High Court of Australia established a principle that reshaped informed consent in this country: a doctor has a duty to warn a patient of a material risk inherent in a proposed treatment. The standard is what a reasonable person in the patient’s position would want to know, not what the doctor thinks is important to disclose.
More than thirty years later, the practical implication of this ruling is still widely misunderstood. Many clinicians and healthcare organisations treat a signed consent form as evidence of informed consent. It is not. A signature is evidence that the patient held a pen. The legal standard requires evidence of comprehension.
What the law actually requires
Informed consent in Australian law requires three elements. First, the patient must be provided with information about the nature of the procedure, its risks, its benefits, and the available alternatives. Second, the information must be communicated in a way the patient can understand. Third, the patient must voluntarily agree to the procedure based on that understanding.
A consent form can document the first element: what information was available. It cannot document the second or third. Whether the patient understood the information, and whether their agreement was based on that understanding, requires evidence beyond a signature.
This is why consent-related negligence claims succeed even when a signed form exists. The form proves availability of information. It does not prove comprehension.
The gap between legal standard and clinical practice
In practice, consent in most Australian healthcare settings works like this: a patient is handed a paper form, often in a waiting room or pre-operative area, under time pressure. The form may be several pages of dense clinical and legal text. The patient signs. The form is filed.
No one records whether the patient read the form. No one verifies whether they understood the risks. No one documents how long they spent reviewing the material. If a dispute arises months or years later, the only evidence is the signed form itself.
This gap between what the law requires and what clinical practice documents is where medico-legal risk concentrates. It is also where GetConsent is designed to operate.
Documenting comprehension, not just acknowledgement
GetConsent addresses the comprehension gap through several mechanisms. Patients review consent content on their own device, at their own pace, in their preferred language. The platform records which sections were viewed and for how long.
Validated comprehension questions verify that the patient understood key concepts before proceeding to signature. The platform records each attempt at each question, documenting not just the final answer but the process of reaching understanding.
The result is an evidence pack that documents not only what information was provided, but how it was consumed and whether comprehension was verified. This aligns the consent record with the legal standard that Australian courts have articulated for decades.
Moving from compliance to evidence
The shift from signature-based consent to comprehension-based consent is not just a medico-legal risk mitigation strategy. It is a patient care improvement. Patients who understand their procedure, its risks, and its alternatives make better decisions, experience less anxiety, and report higher satisfaction.
For healthcare organisations, the question is not whether the legal standard requires comprehension (it has for over thirty years). The question is whether your consent process produces evidence that comprehension occurred. If it does not, the signed form is doing less work than you think.
