Patient Shielding in CHI

From May 2022, patients undergoing X-ray, fluoroscopy or CT examinations in CHI will no longer have shields placed on them during the exposure.

Introduction

This change of practice is based on years of research and technological improvements which means the levels of radiation used with modern imaging technology are significantly less than what they were when the practice of shielding was introduced.

Research also shows that parts of the body usually shielded - like the testicles and ovaries - are much less sensitive to radiation than we thought in the past, thus there is no benefit from placing shields on your child.

Studies have also shown that some shields can cover parts of your child’s body that are important for the doctor to see which could cause the exam to be repeated. Removing these shields will result in a more positive patient experience as it will avoid potential discomfort experienced by the patient and the manual handling issues for the staff, as well as avoiding a potential infection control hazard.

Why is my child not shielded if I am required to wear a lead apron while I am in the room with them?

Your child’s doctor wants an X-ray so that they can better see what is going on inside your child’s body. This exposes your child to a little bit of radiation. Your doctor has thought about the benefits and risks to your child and decided that the benefit from having the information from the image is much higher than the risk from the radiation, which is very small.

It is CHI policy that only the patient is exposed to the radiation as requested by their doctor. All other persons present in an X-ray / CT / Fluoroscopy room must either wear a lead apron or stand behind a lead screen.

Keys Points to remember

  • Technology advances in the 70 years since shielding was first introduced has led to a significant reduction in patient doses.
  • All CHI imaging equipment have been optimised for use with children to ensure the lowest amount of x-ray radiation is used to acquire a diagnostic image.
  • The amount of radiation which falls on areas outside the main field of view is negligible.
  • Over 50 years of research have shown that radiation levels used in modern X-ray exams have no fertility or hereditary effects.
  • Shields can potentially cover important anatomy which would cause repeat imaging.
  • Should the patient move during the exam, the shield may also move and block the view of the area being imaged. This would also lead to repeat imaging.
  • Shields can cause discomfort and are a potential infection control risk.
