With the advent of the transposition of the new Basic Safety Standard into Irish Law there is an imperative on all health providers using ionising radiation to record, provide and optimise radiation dose to patients and accordingly to staff. Radiation dose management tools (RDMT), such as DoseWatch, Radimetrics, etc., are beneficial in aiding Medical Physics Experts on a day to day basis responding to individual patient doses (micro level) and Radiation Protection Advisors will use it on a population based perspective (macro level). In our hospital, GE DoseWatch is installed on Cath Labs, IR, CT and DR (high dose or high-volume modalities). We have recently replaced all of these systems and the RDMT has proved effective for establishing Dose Optimization Teams (DOT), comprising physics, radiologists and radiographers to set dose alert levels and to highlight opportunities for dose reduction. This study will show the advantages of a RDMT over a manual entry system and what that means for both patients and staff exposure, over time. This study reviews the effectiveness of DOTs. This study is undertaken over the past few months for the most frequent scans, using several modalities and results are then reviewed in conjunction with reports such as the COMARE 16th Report and SIR Guidelines 2009. We also undertook a holistic review of patient and staff doses in the Cath Lab, in concurrence with a recent position document published by the EHRA, regarding staff with reproductive potential and during pregnancy.
