Does a Multidisciplinary Pediatric Stone Center Improve Outcomes?

Urolithiasis is becoming more prevalent in children in the United States. A multidisciplinary pediatric stone center was initiated in 2014 to address this growing public health issue. The purpose of this manuscript is to assess the development of the stone center and its clinical outcomes. A retrospective cohort study was performed to assess clinical outcomes. Inclusion criteria included patients younger than 21 years of age with more than 6 months of followup. Data abstracted from the medical record included patient demographics, medications, imaging, metabolic evaluations, surgical procedures, and emergency department visits. The number of surgical procedures, emergency department visits, and computerized tomography scans were compared before and after the first visit to the stone center. A total of 353 patients were evaluated in the stone center during the study period, 264 (98 male, 166 female) of whom met inclusion criteria. The mean age was 14.5 years, and the mean followup was 1.1 years. Of all patients 60% had a metabolic abnormality. Prior to the first visit 104 patients underwent surgery. Surgical procedures decreased from 39% to 17% during the year before and at any time after the first visit (p <0.0001). Emergency department visits per year decreased from 1.4 to 0.6 before and after the first visit (p <0.0001). Computerized tomography scan use decreased from 32% to 24% (p=0.3). A multidisciplinary stone center can be a feasible option to coordinate care and improve clinical outcomes. In our series the number of surgical procedures and emergency department visits decreased after enrollment.
