Methods and materials
For this audit, the Royal College of radiologists (RCR) collaborated with the Royal College of Physicians (RCP) and Royal Osteoporosis Society (ROS).
Radiology department audit leads across the UK were invited to participate and send audit data to the RCR on behalf of their department. The audit leads were sent an instruction book and two questionnaires which comprised the following:
1) First, an online questionnaire about the department to be completed by audit lead. This was to assess the reporting infrastructure and referral pathways.
2) Second, an audit template to complete for 50 consecutive CT scans of the chest, abdomen and pelvis in patients over 70. Exclusion criteria included trauma CT’s and bony metastases or myeloma.
As part of the CT analysis the auditor was required to review the CT and perform sagittal reformates in order to identify vertebral fragility fractures. These were then to be graded using the Genant method.
The Genant classification is outlined in image 2
A series of key audit standards were devised using the Royal Osteoporosis Society (ROS) guidelines. These will be outlined in the next section.
