Relationship between the functional status scale and the pediatric overall performance category and pediatric cerebral performance category scales

Abstract

IMPORTANCE: Functional status assessment methods are important as outcome measures for pediatric critical care studies. OBJECTIVE: To investigate the relationships between the 2 functional status assessment methods appropriate for large-sample studies, the Functional Status Scale (FSS) and the Pediatric Overall Performance Category and Pediatric Cerebral Performance Category (POPC/PCPC) scales. DESIGN, SETTING, AND PARTICIPANTS: Prospective cohort study with random patient selection at 7 sites and 8 children's hospitals with general/medical and cardiac/cardiovascular pediatric intensive care units (PICUs) in the Collaborative Pediatric Critical Care Research Network. Participants included all PICU patients younger than 18 years. MAIN OUTCOMES AND MEASURES: Functional Status Scale and POPC/PCPC scores determined at PICU admission (baseline) and PICU discharge.We investigated the association between the baseline and PICU discharge POPC/PCPC scores and the baseline and PICU discharge FSS scores, the dispersion of FSS scores within each of the POPC/PCPC ratings, and the relationship between the FSS neurologic components (FSS-CNS) and the PCPC. RESULTS: We included 5017 patients.We found a significant (P
