Use of Pediatric Outcomes Data Collection Instrument to Evaluate Functional Outcomes in Multiple Hereditary Exostoses

BACKGROUND: The Pediatric Outcomes Data Collection Instrument (PODCI) is a validated quality-of-life questionnaire with 6 domains designed to provide a standardized method of measuring outcomes in pediatric musculoskeletal conditions. To our knowledge there are no reports on its use in children with multiple hereditary exostosis (MHE).

QUESTIONS/PURPOSES: Most published studies on MHE patients have described the efficacy of specific surgical techniques or the specification of deformities. Little is known about the general health status of pediatric patients, the severity of pain, loss of function, and how MHE influences the activities of daily life. We aim to assess the functional levels of MHE pediatric patients with PODCI questionnaire.

PATIENTS AND METHODS: As a cross-sectional study, we prospectively administered PODCI to 34 pediatric patients diagnosed with MHE and their families. The score distributions were compared with values published earlier for children and adolescents without musculoskeletal disorders using the Student and Welch t tests. Parents and adolescents' reports were compared using Wilcoxon signed rank test. Physical examination and PODCI score relation were evaluated by Spearman test.

RESULTS: Children with MHE have significantly lower scores ( P <0,05) in comparison with unaffected children in all domains using the Student and Welch t test. Parents score differs from children score with statistically relevance in pain and comfort domain ( P <0,5). The Spearman test showed a negative correlation between physical examination and PODCI score with statistical significance.

CONCLUSIONS: These results point towards PODCI's capacity in evaluating functional outcomes of pediatric patients with MHE.

LEVEL OF EVIDENCE: Diagnostic Study, Level III.
