I do not have great things to say about the treatment my mother received at the Watford General Hospital, X-Ray department, I'm afraid. She arrived there for a CT scan, however was told to drink 1 litre of water and wait 1 hour. My mother had to point out that she is not there for a kidney procedure but for a CT scan. Following which, the hospital staff member (named Avneet) realised her error, tried to brush it off and proceeded to give her a contrast dye via injection. However, due to poor placement of the injection, my mother's arm started to bruise and form a large visible lump. This is caused when it starts to bleed outside the vein resulting in Infilteration or Hematoma. My mother, being a Registered nurse herself, was able to identify this issue and point it out. However, someone who does not have a medical background or knowledge might not have recognised these signs. I was very disappointed with this poor service and hope that errors like this will not continue in the future. Either nurses should be the ones to do tasks like these (Avneet did not look like one, no uniform etc.), or your staff should be trained properly being being in a patient facing role. Aside from this, her scan proceeded as normal and she was treated well by the doctors.
