Abstract

Summary: Introduction: There is growing recognition of the importance of patient-reported outcomes (PROs) in pediatric hypospadias. We have previously presented a conceptual framework for Hypospadias-Specific Health-Related Quality of Life (HRQoL), which posited 5 domains of HRQoL in this population. The framework components (domains) included penile appearance, voiding function, social function, psychological/behavioral function, and pubertal/sexual health. In this work, we investigated the established validity and relevance of PROs within each of these domains for patients with hypospadias. Materials and methods: We evaluated existing measures with published psychometric data, including validation data, in the hypospadias population. We also assessed the available data on each measure according to the guidelines of the Scientific Advisory Committee of the Medical Outcomes Trust (Table) in order to establish measure quality. We also examined the power of existing validation studies according to suggested guidelines for psychometric validation and factor analysis. Discussion: Available validated measures in the hypospadias population have focused primarily on penile appearance and to a lesser degree on pubertal development/sexual health. There were no validated disease-specific measures with dedicated evaluations of other key HRQoL domains including voiding-related sequelae, social function, or psychological function. In addition, no single measure addressed all of the quality guidelines posed by the Scientific Advisory Committee. Conclusions: Current generalized measures for PROs lack relevance to the experience of hypospadias patients, and disease-specific assessments are often focused on penile appearance. Improving measure quality is necessary to optimize the value of our assessments and better help our patients with hypospadias.
