PURPOSE: Complication rates of 5% to 10% and 12% to 23% have been observed following distal and proximal hypospadias repair, respectively. However, these rates may be overreported. We hypothesized that data from the Pediatric Health Information System would corroborate the complication rates reported in the literature and refute the rates established by U.S. News & World Report as quality metrics. MATERIALS AND METHODS: The Pediatric Health Information System database was interrogated for hypospadias and revision CPT® codes. To evaluate the appropriateness of the U.S. News & World Report code list to identify revisions, 3 CPT groups were defined. Group A included codes sought by U.S. News & World Report, group B included group A plus codes for acquired urethrocutaneous fistula in males and group C included group B plus any revision codes associated with the index procedures. To evaluate the appropriateness of U.S. News & World Report followup interval, we assessed revision rates with ever increasing followup intervals out to 7 years. Yearly revision rates were summarized by median and quantile to correlate whether median revision rates changed significantly depending on whether increased followup or enhanced code lists were used. RESULTS: Average complication rates for group A were 3.32% (range 0.48% to 7.36%) and 12.29% (3.48% to 36.36%) for distal and proximal repairs, respectively. Revision rates increased significantly from group A (median 3.32%) by inclusion of a more expansive list of CPT codes associated with revision procedures (group B, 4.26%, p <0.001 and group C, 6.37%, p <0.001) in distal hypospadias. Among proximal hypospadias cases this difference was not significant when comparing group A (12.29%) to group B (12.53%, p=0.813), but was significant when comparing group A to group C (22.14%, p <0.001). Median revision rates for distal and proximal hypospadias increased with longer followup for all 3 groups, although the upward trend was not statistically significant. CONCLUSIONS: Depending on how one defines hypospadias revision, no hospital within the Pediatric Health Information System data set meets the U.S. News & World Report definition of perfection, a finding that is supported by recent reports from some of the largest, most prolific and most highly regarded pediatric urology programs. We posit that the U.S. News & World Report quality metrics do not accurately reflect the nature of hypospadias surgery complication rates.
