Insights
The Pediatric Outcomes Data Collection Instrument (PODCI) reliably measures physical functioning in children with osteogenesis imperfecta (OI). This patient-reported outcome measure provides valuable health status insights for intervention studies.
Area of Science:
- Pediatric Orthopedics
- Clinical Trial Endpoints
- Patient-Reported Outcome Measures (PROMs)
Background:
- PROMs are crucial for assessing patient health status in clinical research.
- The Pediatric Outcomes Data Collection Instrument (PODCI) is a PROM for pediatric musculoskeletal disorders.
- Osteogenesis imperfecta (OI) is a genetic disorder affecting bone fragility.
Purpose of the Study:
- To evaluate the validity and reliability of the PODCI in children diagnosed with osteogenesis imperfecta (OI).
- To assess physical functioning and psychological well-being using PODCI in a large OI cohort.
Main Methods:
- A multicenter study enrolled 417 children with OI types I, III, and IV.
- PODCI assessed physical functioning and psychological well-being.
- PODCI physical function scores were correlated with the Brief Assessment of Motor Function (BAMF) and psychological well-being scores.
Main Results:
- Children with OI type III exhibited significantly lower physical function scores compared to types I and IV.
- No significant differences in psychological well-being were observed across OI types.
- PODCI demonstrated moderate-to-strong correlations with BAMF, indicating good validity for physical function.
Conclusions:
- The PODCI is a reliable instrument for measuring physical functioning in pediatric OI patients.
- PODCI offers valuable insights into patient-reported health status for OI.
- This PROM can inform the evaluation of interventions for children with OI.
Purpose:
Patient-reported outcome measures (PROMs) are increasingly recognized as valuable endpoints in clinical trials. The Pediatric Outcomes Data Collection Instrument (PODCI) is a PROM utilized in children with musculoskeletal disorders. We evaluated the validity and reliability of PODCI in children with osteogenesis imperfecta (OI).
Methods:
Physical functioning and psychological well-being were assessed using PODCI in a large cohort of children enrolled in a multicenter study conducted by the Brittle Bone Disorders Consortium. Physical function scores were correlated with a validated, observer-rated scale, Brief Assessment of Motor Function (BAMF), and with psychological well-being scores. We calculated sample sizes required to detect clinically meaningful differences in physical function.
Results:
Four hundred seventeen children with OI types I, III, and IV were enrolled. Physical function scores in OI type III were significantly lower than those in OI types I and IV. There were no significant differences in psychological well-being. PODCI physical function scores showed moderate-to-strong correlation with BAMF. The Global Functioning Scale, a composite of physical function, did not consistently correlate with psychological well-being.
Conclusion:
PODCI can be a reliable measure of physical functioning in children with OI and offers valuable information about patient-reported health status and new ways to examine the utility of interventions in this population.
