Advocating for Change: Unveiling the Challenges of an Ultrasound-First Approach in Uncomplicated Renal Colic.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIn recent years, medical literature has advocated for an ultrasound-first (US-first) approach for the diagnosis of uncomplicated renal colic. Despite these recommendations, computed tomography (CT) continues to be overutilized.
objectiveThis project had a three-pronged approach: 1) to investigate the current diagnostic choice and factors that influence it for uncomplicated renal colic within our local healthcare system, 2) to create and implement an algorithm to emphasize the use of a US-first approach for uncomplicated patients, and 3) to identify the effectiveness of the clinical algorithm.
methodsAn initial five-month retrospective evaluation (2020-2021), including regional and tertiary emergency departments (EDs), was performed to review emergency provider practice patterns when investigating renal colic. In conjunction with this, a clinician survey was performed to identify factors affecting providers' choice of diagnostic imaging for renal colic. Next, a multidisciplinary group of providers developed a clinical algorithm advocating for a US-first approach to diagnosing uncomplicated renal colic. Finally, a postintervention retrospective evaluation was conducted in 2023 to evaluate the effectiveness of this clinical algorithm.
resultsThe initial retrospective study showed CT as the primary diagnostic choice (used in 102 out of 135 patients) for investigating uncomplicated renal colic. After the implementation of the clinical algorithm, there was a significant reduction in CT scans by 14.2% (p = 0.016). There were no significant differences in the need for urological interventions, hospitalization, repeat ED visits within one week, or missed serious diagnoses.
conclusionsThis study demonstrated the effectiveness of a multidisciplinary-derived clinical algorithm in successfully reducing the use of CT scans in uncomplicated renal colic. The US-first approach was utilized in a higher percentage of patients following the introduction of the clinical algorithm; however, CT still dominated as the primary diagnostic choice.
