This guidance looks at procedures used for diagnosis or treatment. It considers if they are safe and work well enough for wider use in the NHS.
An interventional procedure covers a broad range of topics. It can include things like:
- making a cut or a hole to gain access to the inside of a patient's body
For example, carrying out an operation or inserting a tube into a blood vessel. - gaining access to a body cavity without cutting
For example, carrying out treatment inside the stomach using an instrument inserted via the mouth. - using electromagnetic radiation
For example, using a laser to treat eye problems.

New guidance needed?
Anyone can tell us about a procedure for consideration. We want to know if there are:
- new or not
well established procedures that you think we should develop guidance on - established procedures that need to be reviewed and updated.

Safely introduce new procedures into your practice

If an IPG exists, ensure that the procedure is done in accordance with the guidance.

If we haven't published an IPG for the procedure your organisation can still approve it as long as:
- the clinician has appropriate training and experience
- patients are made aware of the circumstances under which the procedure is being performed, and consent to this
- arrangements are made for data collection and clinical audit.
