Methods and materials
Dose Area Product (DAP) Gycm2 was chosen as the most relevant metric to facilitate comparison with existing national and European DRLs.
Data was collected over a twenty three month period for over five thousand eight hundred examinations spanning a wide range of cardiac procedures across the three cardiac laboratories.
This data enabled the median (Q50)and 75th percentile (Q75) values to be calculated for each procedure in each laboratory.
The 75th percentile values may be used as local DRLs in each of the three cardiac laboratories.
Categories of procedure used in this audit include general cardiac procedures,
structural cardiac interventional procedures,
Percutaneous Transluminal Coronary Angioplasty (PTCA) procedures,
pacemaker procedures,
electrophysiology (EP) procedures and peripheral procedures with a number of specific examinations within each category.
A description of the classification used for each examination is given in Fig.2 and Fig.3 which also includes the number of examinations counted (n) for the purposes of the audit in each category.
