When NHS consent form 3 is the right choice
Form 3 is optional in the NHS form set. Trusts use it where a written record is wanted but the full anaesthetic disclosure on form 1 would be disproportionate.
- Minor skin surgery and lesion removal under local anaesthetic
- Endoscopy or cystoscopy performed without sedation
- Joint injections, biopsies and vasectomy
- Imaging with contrast, alongside an X-ray consent form where radiation is involved
It can be signed by the patient themselves or by a person with parental responsibility for a child, which is why the template carries both signature routes.
Why staying conscious changes the consent conversation
A conscious patient can withdraw consent mid-procedure, so the discussion should cover what will be felt, how long it will take, and how to signal that they want to stop.
That practical detail matters more here than the extra-procedures wording used on form 1. Nothing significant should be added to the procedure without pausing to ask.
Risks worth recording on a minor procedure consent form
Minor does not mean risk-free. Record the risks that a reasonable patient in this position would want to know about before agreeing.
- Bleeding, bruising and infection at the site
- Scarring or altered sensation after skin surgery
- Failure of the procedure, or the need to repeat it
- Reaction to local anaesthetic
Country variants for outpatient consent
The distinction between conscious and unconscious procedures is handled differently outside the UK, though the disclosure duty is comparable.
United Kingdom
NHS trusts publish form 3 as an optional short-form record, backed by GMC decision-making guidance and the Mental Capacity Act 2005.
United States
Office-based procedures typically use a single clinic consent document under state informed-consent statutes, with no separate conscious-procedure form.
Canada, Australia and New Zealand
Provincial and state services generally use one consent form for all procedures, with the anaesthetic section left blank when none is used.
When verbal consent is enough instead
Not every conscious procedure needs a signature. Taking a blood sample or performing a routine examination is normally covered by verbal or implied consent, recorded in the notes.
Use form 3 where the procedure is invasive, carries a meaningful complication rate, or where the patient may reasonably want a written record of what was agreed.
Filing and follow-up
File the signed form in the clinical record and offer the patient a copy. Where the procedure is repeated at intervals, take fresh consent rather than relying on a form signed months earlier.
If the procedure escalates and sedation becomes necessary, stop and take consent again on the appropriate form, in the same way you would for a surgery consent form.
