ED-KSS Trial Summary

This trial found that a shared approach to diagnostic decision-making reduced radiation exposure and improved engagement and the quality of Emergency Department care.

Who is the study for?
This trial is for adults aged 18-55 who have acute flank pain possibly due to kidney stones and are at low risk for other serious conditions. They must be capable of making medical decisions and not have signs of systemic infection, recent surgeries, or certain health complications like a history of one kidney.Check my eligibility
What is being tested?
The study tests if shared decision-making between patients and doctors about imaging for suspected kidney stones can reduce unnecessary CT scans. It compares this approach with the usual physician-directed decision-making process.See study design
What are the potential side effects?
Since the interventions involve decision aids and educational materials rather than medications, there are no direct side effects. However, choosing less imaging could miss other diagnoses or delay treatment.

ED-KSS Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Shared Decision-Making (via Decision Aid)Experimental Treatment2 Interventions
The intervention is a decision aid, which both encourages and facilitates a shared decision-making conversation between the clinician and the patient. The decision aid educates patients regarding evidence-based approaches to the management of suspected kidney stones in the ED. Clinicians will receive training specific to this decision aid, though the decision aid is designed to be used with no additional training.
Group II: standardized educational intervention (pamphlet +usual care)Active Control1 Intervention
The control arm will receive Usual Care and a standardized educational intervention (pamphlet). This intervention (pamphlet) contains information about kidney stones. Usual care for this clinical scenario generally involves the clinician choosing the management plan. Clinicians of subjects assigned to the usual care group will be asked to practice usual, evidence-based medical care, without shared decision-making.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What conclusions is this research seeking to reach?

"Over the course of 12 months, this medical trial will monitor CT scan rate as its principal metric. Secondary outcomes include patient satisfaction (as measured through HCAHPS scores ranging from 0 to 10), occurrence of shared decision-making according to OPTION-5 scoring (where higher marks reflect more SDM involvement) and an overall assessment of radiation burden as reported in numeric DLP values extracted from CT reports."
