A clinical audit conducted at Sheikh Khalifa Medical City in Abu Dhabi, United Arab Emirates, and published in Cureus demonstrated that introducing a standardized renal colic pathway and departmental education significantly increased the administration of first-line nonsteroidal anti-inflammatory drugs (NSAIDs) for emergency room patients. The two-cycle retrospective study evaluated a total of 200 adult patients across two distinct timeframes to measure emergency department practices against nine quality standards derived from Royal College of Emergency Medicine (RCEM) and National Institute for Health and Care Excellence (NICE) guidelines.
How the Two-Cycle Audit Evaluated 200 Renal Colic Patients
The primary audit examined a convenience sample of 100 adult patients presenting with renal colic, ureteric colic, or urinary stones between December 2020 and December 2024. A re-audit evaluated an additional 100 patients admitted between March and September 2025 following a targeted implementation phase. Data collectors utilized electronic health records under the supervision of an emergency department consultant.
During the primary audit phase, researchers found that 73 percent of the 100 patients were men and 27 percent were women, with a mean age of 43 years. Initial assessments showed that pain scores were documented in all 100 cases. Complete blood count, renal function testing, and noncontrast computed tomography (CT) imaging met high compliance thresholds during both audit cycles.
Implementation of the Standardized Analgesia Pathway
Between January and March 2025, the hospital executed a structured implementation phase. Department leaders presented primary audit findings at a departmental meeting, distributed an educational infographic as an aide-mémoire, and launched a standardized renal colic pain pathway. This pathway designated NSAIDs as the first-line medication choice, followed by intravenous paracetamol, and restricted opioid analgesia to cases where preceding options proved ineffective or contraindicated.
Following these interventions, first-line NSAID administration rose from 39 percent in the primary audit to 60 percent in the re-audit. This represented an absolute increase of 21 percentage points, which researchers confirmed as statistically significant. Meanwhile, the avoidance of first-line opioid administration increased slightly from 89 percent to 94 percent, though this specific change did not reach statistical significance.
Comparison of Clinical Indicators Between Audit Cycles
While NSAID prescribing improved markedly, several other clinical indicators remained steady between the two evaluation periods. Urine dipstick testing was performed in 85 percent of primary audit patients and 84 percent of re-audit patients. Complete blood count and renal function testing achieved 100 percent compliance across both groups.
Comparative Management Approaches in United Kingdom Emergency Services
In a separate multisite evaluation reported from a National Health Service (NHS) Trust in the West Midlands, England, and documented on PMC, researchers reviewed 417 patients with suspected acute renal colic. That retrospective review compared local practices against NICE and British Association of Urological Surgeons guidelines.
The UK cohort revealed an average patient age of 47.4 years with a nearly even gender distribution. While diagnostic completion times for CT scans of the kidneys, ureters, and bladder averaged nine hours with minimal delay, the study noted that NSAIDs remained underutilized despite formal guideline recommendations, contrasting with the successful increase achieved following the Abu Dhabi pathway implementation.
Frequently Asked Questions About Renal Colic Audits
What specific guidelines were used to benchmark emergency department care?
Researchers derived nine clinical criteria from the Royal College of Emergency Medicine audit framework and the National Institute for Health and Care Excellence guideline NG118.
What were the exact timeframes for the patient cohorts evaluated in Abu Dhabi?
The primary audit evaluated 100 patients presenting between December 2020 and December 2024, while the re-audit assessed 100 patients presenting between March and September 2025.
How did the implementation phase change medication delivery?
First-line administration of nonsteroidal anti-inflammatory drugs increased by an absolute 21 percentage points, rising from 39 percent to 60 percent following staff education and pathway deployment.
