Optimising Urinary Tract CT Scans for Renal Colic: Enhancing Efficiency and Reducing Radiation

Our interventions resulted in adherence to the accepted standard doubling over a four-month period. Average ionising radiation exposure has been significantly reduced, which reduces the risk of carcinogenesis. Both interventions carried out in this study are low fidelity and are readily reproducible on a national scale. This study encourages radiology departments to audit radiation exposure from CT scans of the urinary tract for suspected renal colic, according to national standards. Future work should focus on multi-centre implementation to validate generalisability, assess long-term sustainability of behaviour change, and quantify the cumulative dose savings at a population level.
