The Pediatric Outcomes Data Collection Instrument (PODCI) as Performance Measure, Comparing General Population with Cerebral Palsy Population Using the Gross Motor Function Classification System Levels I-V

Abstract

OBJECTIVES Compare results of the Pediatric Outcomes Data Collection Instrument (PODCI) in children ages 2-18 years with cerebral palsy (CP) across all severity levels of the Gross Motor Function Classification System (GMFCS) with children in the General Population, confirming discriminant validity as a performance assessment tool and health-related quality of life (HRQOL) measure.

METHODS Cross-sectional study: single response PODCI proxy survey databases of 5238 children ages 2-18 years in GP and 2470 in the Population with CP were analyzed. Statistical methods included Analysis of Variance (ANOVA), Analysis of Covariance (ANCOVA), Linear Trend Test, and Standard Error Assessment.

RESULTS A statistically significant difference exists between PODCI subscales in General Population and Population with CP across age groups and GMFCS levels. Motor scales and Global Functioning increase with age in both populations and are inversely proportional to GMFCS level in the Population with CP. HRQOL measures decrease with age in both populations with Happiness decreasing more in the General Population than those with CP as age increases.

CONCLUSIONS PODCI demonstrates a statistically significant difference in motor performance and HRQOL in children ages 2-18, between the General Population and the population with CP. PODCI is a valid performance assessment tool for use in CP ages 2-18 across all GMFCS levels.

I confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.

Yes

I understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov. I confirm that any such study reported in the manuscript has been registered and the trial registration ID is provided (note: if posting a prospective study registered retrospectively, please provide a statement in the trial ID field explaining why the study was not registered in advance).

Yes

I have followed all appropriate research reporting guidelines, such as any relevant EQUATOR Network research reporting checklist(s) and other pertinent material, if applicable.
