CQC updates guidance on accidental exposures

Latest version of IR(ME)R also includes notification criteria for incorrect radiopharmaceutical administration

Published: 16 May 2023 Radiation protection

The updated version of clinically significant accidental and unintended exposures (CSAUE) guidance and the statutory notification form have now been published by the Care Quality Commission (CQC).

Since the August 2020 version of this guidance was published, the CQC has updated the information on CSAUE, added notification criteria for incorrect radiopharmaceutical administration, revised some codes in the table, and amended the notification criteria for interventional radiology and cardiology, radiotherapy and foetal dose.

The changes include:

  • An increase in the reporting threshold for verification exposures in radiotherapy from 20% to 50%.
  • An increase in the notification threshold from 1mGy to 10mGy in foetal dose – but where previously a procedural failure was needed to instigate reporting, this is no longer the case. You must now report if a foetus has an exposure over 10 mGy, even when procedures were followed.
  • An amendment to the criteria for when to investigate and notify the enforcing authority.
