title: PATIENT DOSE ASSESSMENT AFTER INTERVENTIONAL CARDIOLOGY PROCEDURES: A MULTI-CENTRIC APPROACH TO TRIGGER OPTIMISATION.
abstract: As the number and complexity of fluoroscopically guided interventions increase, a serious effort has to be put on the optimisation of the X-ray dose delivered to the patient. In order to set up this optimisation process, the clinical practice for a given cardiology centre has to be analysed with relevant statistical power and compared with the data at local or national level. Data from 8 Swiss cardiology centres for 10 different vascular and heart rhythm procedures have been collected. The collected dose indicators were, when available, cumulated air kerma, cumulated dose-area product, fluoroscopy time and the number of images per procedure. Data analysis was performed using an in-house software solution in terms of the first, second and third quartiles. This kind of large-scale analysis could yield some onsets towards local practice optimisation based on anonymous dose indicator cross-comparison. Further effort should nevertheless be made in order to proceed towards an operator-based data analysis, thus allowing for an individual practice optimisation.
