Standard:
Local departmental policy states that the acquisition area for CT KUB should be from the superior border of the kidneys to the symphysis pubis.4
Indicator:
Vertebral level at which CT KUB scan commenced.
Target:
100% of CT KUB scans should commence at T10–T12 or within two vertebral body levels above the superior border of the kidney if above T12.
Methodology:
Retrospective review of 100 consecutive CT KUB examinations from 17/3/14–30/4/14 performed at Hairmyres hospital.
All data accessed from local radiology information system (RIS).
Data collected included: vertebral level at which kidneys fully included and scan commenced,
patient dose and number of images acquired.
Results of 1st audit round:
100% of kidneys fully imaged at T10.
42% scans commenced within agreed target range.
Mean dose =473 milliGray/cemtimetre2 (mGycm2).
Mean image number =453.
1st action plan:
Data presented at local departmental audit meeting and discussed with consultant radiologists and senior radiographers.
Agreement made to reduce scan field; T10 defined as the upper limit of the acquisition area.
Re-audit.
Results of 2nd round:
A further 100 consecutive CT KUB examinations from 03/07/2014 - 13/08/2014 were reviewed.
