Summary
Radionuclide cystography (RNC) is significantly more cost-effective than voiding cystourethrography (VCUG) for diagnosing vesicoureteral reflux in children. Utilizing RNC can lead to substantial cost savings for healthcare institutions.
Area of Science:
- Pediatric Radiology
- Medical Imaging Cost Analysis
Background:
- Vesicoureteral reflux (VUR) is a common condition in children.
- Accurate diagnosis of VUR is crucial for appropriate management and prevention of kidney damage.
- Voiding cystourethrography (VCUG) and radionuclide cystography (RNC) are primary diagnostic imaging modalities for VUR.
Purpose of the Study:
- To compare the direct costs associated with voiding cystourethrography (VCUG) and radionuclide cystography (RNC) for evaluating pediatric vesicoureteral reflux.
Main Methods:
- A comparative cost analysis was performed using time and motion studies to track personnel and material usage for 25 VCUG and 25 RNC procedures.
- Direct variable and fixed costs were calculated based on labor, materials, and hospital accounting records.
- Statistical analysis, including Student t-tests, was used to compare the mean total direct costs between the two imaging techniques.
Main Results:
- Radionuclide cystography (RNC) demonstrated a significantly lower mean total direct cost ($64.58) compared to voiding cystourethrography (VCUG) ($112.17) (P < .0001).
- VCUG examinations were 1.74 times more expensive than RNC examinations for evaluating pediatric vesicoureteral reflux.
Conclusions:
- Radionuclide cystography (RNC) offers substantial cost savings compared to voiding cystourethrography (VCUG) for diagnosing vesicoureteral reflux in children.
- Healthcare institutions can achieve significant financial benefits by prioritizing RNC when clinically indicated for pediatric VUR evaluation.
