Insights
To reduce overuse of ultrasound for pediatric appendicitis diagnosis, a white blood cell (WBC) count of 10,000/μL was identified as a key criterion. Implementing this could decrease ultrasound use by nearly 50%.
Area of Science:
- Pediatric Radiology
- Diagnostic Imaging
- Emergency Medicine
Background:
- Institution replaced CT scans with ultrasound for pediatric appendicitis diagnosis due to similar effectiveness.
- Overutilization of ultrasound became an unintended consequence.
- Need to establish measures to prevent ultrasound overuse.
Purpose of the Study:
- To identify measures to prevent the overuse of ultrasound in diagnosing appendicitis in children.
- To establish criteria for appropriate ultrasound utilization.
Main Methods:
- Retrospective chart review of 327 pediatric patients evaluated for appendicitis.
- Analysis of clinical, radiographic, and histopathologic findings.
- Determination of diagnostic accuracy of ultrasound (US) and white blood cell (WBC) values.
- Development of a management algorithm.
Main Results:
- All 327 patients underwent ultrasound for suspected appendicitis.
- A WBC count of ≥10,000/μL was identified as a primary discriminant for management and US utilization.
- Utilizing WBC count ≥10,000/μL as a criterion could have reduced US utilization by 49.5%.
Conclusions:
- Clinical examination, WBC count, and surgical consultation can reduce the need for ultrasound in pediatric appendicitis.
- Implementing a WBC count threshold can significantly decrease unnecessary ultrasound examinations.
- Optimizing diagnostic pathways improves resource allocation in pediatric imaging.
Background:
With similar effectiveness of ultrasonography, our institution replaced CT imaging with ultrasound for diagnosing appendicitis in children. An unexpected consequence was the overutilization of ultrasound. Our objective was to establish measures that could help prevent this overuse.
Methods:
A retrospective chart review of 327 consecutive pediatric patients evaluated for appendicitis between October 2014 and September 2015 at our institution was performed. Data on clinical, radiographic, and histopathologic findings were reviewed. Diagnostic accuracy of US and white blood cell (WBC) values was determined. An algorithm was created.
Results:
327 (100%) patients received an ultrasound for suspected appendicitis. WBC of 10,000/μl was determined to be the primary discriminant for management and ultrasound utilization. If a WBC ≥10,000/μL had been utilized as criteria for imaging, 49.5% fewer patients would have received an ultrasound.
Conclusions:
Clinical exam, WBC count, and surgery consultation prior to ultrasonography can lessen then need for ultrasound utilization in children with suspected appendicitis.
