Informed consent


More than a signature

Documenting consent

  • major risks discussed
  • minor but important risks mentioned
  • any questions the patient asked
  • answers given
  • the patient's apparent understanding (especially if it is a young person, or one whose mental capacity or competency might be questioned)
  • any handout materials provided to the patient

Print material, videos, or other handouts support the consent discussion but do not replace it.

What is the purpose of a consent form?

  • A consent form itself is not the consent.
  • The dialogue with the patient is the key element of the consent process.
  • Follow hospital requirements, if applicable, for completing a consent form.

In many Canadian jurisdictions it is now a legal requirement that a consent form be completed before any surgical procedure is undertaken in a hospital. The consent form itself is an acknowledgement and serves as documentary evidence that the explanations were given and that the patient agreed to what was proposed.

In witnessing a signature, the witness simply confirms the identity of the patient who signed the document. The witness's role has no other legal significance.
