Introduction: To investigate the actual cost of hematuria evaluation using nationally representative claims data, given that the workup for hematuria burdens the healthcare system with significant associated costs. We hypothesized that evaluation with contrast-enhanced computed tomography (CT) confers more cost to hematuria evaluation than renal ultrasound (US).
Methods: Using a national, privately insured database (MarketScan), we identified all individuals with an incident diagnosis of hematuria. We included patients who underwent cystoscopy and upper tract imaging within 3 months of diagnosis. We tabulated the costs of the imaging study as well as the total healthcare cost per patient. A multivariable model was developed to evaluate patient factors associated with total healthcare costs.
Results: We identified 318,680 patients with hematuria who underwent evaluation. Median costs associated with upper tract imaging were $362 overall, $504 for CT with contrast, $163 for US, $680 for magnetic resonance imaging (MRI), $283 for CT without contrast, and $294 for retrograde pyelogram. Median cystoscopy cost was $283. Total healthcare costs per patient were highest when utilizing MRI and CT imaging. When adjusted for comorbidities, the use of any imaging other than ultrasound was associated with higher costs.
Conclusions: In this nationally representative analysis, hematuria evaluation confers a significant cost burden, while the primary factor associated with higher costs of screening was imaging type. Based upon reduced cost of US-based strategies, further investigation should delineate its cost-effectiveness in the diagnosis of urological disease.
