Summary

This is a randomized trial to determine the effectiveness of a clinical decision support tool on image ordering for patients with suspected nephrolithiasis. Patients who present with acute unilateral flank or abdominal pain in whom emergency department providers suspect nephrolithiasis will receive either the clinical decision support tool or no tool (usual care).

Conditions

  • Nephrolithiasis

Interventions

BEHAVIORAL

Ultrasound-first Clinical Decision Support tool

Intervention: The intervention is the CDS tool, which consists of 4 components: 1. Four questions which assess the appropriateness of ultrasound for this patient 2. A link to the evidence 3. Buttons to remove CT scan and order ultrasound 4. If the CT scan order is kept, reasons why ultrasonography is not appropriate The CDS tool will be placed or integrated into EPIC, at the point of order entry. The tool will be triggered by an order for CT scan for kidney stone. Appropriateness criteria for ultrasound: 1. Adults aged \>18 and \< 76 2. Non-obese (men \< 285lbs, women \< 250lbs) 3. Low risk of Stone Emergency (Obstructing stone and any of the following: urosepsis, renal deterioration, post kidney transplant, solitary kidney, intractable symptoms) 4. Low risk of clinically significant alternative diagnosis (e.g. appendicitis, cholecystitis, AAA, ovarian torsion) If all responses are affirmative, then the subject should receive US, and US order is provided.
