Compliance with NICE, BAUS, RCR, and RCEM Guidelines for Acute Renal Colic: A Two-Cycle Quality Improvement Study at Lister Hospital Emergency Department, United Kingdom

This QIP demonstrated that targeted interventions significantly enhanced adherence to NICE, BAUS, RCR, and RCEM guidelines, reduced diagnostic delays, and improved emergency department efficiency in managing acute renal colic. Scalable strategies, including STONE score integration and streamlined imaging, expedited workflows, increased RCEM four-hour compliance, and boosted metabolic testing rates while reducing repeat CT scans. Non-significant trends in diagnostic yield and alternative diagnoses suggest improved clinical precision without compromising safety, offering a replicable model for optimizing renal colic care within existing resources, pending further multicenter validation.
