Biomarkers of Brain Injury in Critically-Ill Children on Extracorporeal Membrane Oxygenation

VABS-3 is a 381-item caregiver report measure that was developed to assess adaptive behavior. The questionnaire is divided into 4 domains of adaptive behavior: 1) communication, 2) daily living, 3) social skills and relationships, and 4) physical activity. Each item is rated 0 (never), 1 (sometimes), or 2 (usually or often) as how often the child does the behavior independently without help or reminders. The overall adaptive composite score has a mean of 100 and standard deviation of 15 with lower scores indicating worse intellectual disability.

The FSS examines 6 domains of functioning: 1) mental status; 2) sensory; 3) communication; 4) motor function; 5) feeding; and 6) respiratory and each domain receives a score of 1 (normal), 2 (mild dysfunction), 3 (moderate dysfunction), 4 (severe dysfunction), or 5 (very severe dysfunction). Final scores range from 6 to 30 with higher scores indicating greater dysfunction.

PCPC consists of a 6-point scale: 1) normal; 2) mild disability; 3) moderate disability; 4) severe disability; 5) coma/vegetative state; 6) brain death. Higher scores indicating worse performance or functional morbidity

POPC consists of a 6-point scale: 1) good overall performance; 2) mild overall disability; 3) moderate overall disability; 4) severe overall disability; 5) coma/vegetative state; 6) brain death. Higher scores indicating worse performance or functional morbidity

The PedsQL Inventory is a 36-item (for infants 1-12 months), 45 item (for infants 13-24 months) or 23-item (children 2-18) questionnaire with established validity and reliability for health outcomes measurements in pediatric populations, including former PICU patients. The PedsQL is used as a parent proxy report for all ages, as well as self-report in children between 5 and 18 years. The scales are divided into 4 domains of functioning: 1) physical functioning, 2) emotional functioning, 3) social functioning and either 4) cognitive functioning (on the infant scales) or school functioning (on the child scales). Each item on the parent proxy report receives a score of 0 (never), 1 (almost never), 2 (sometimes), 3 (often), or 4 (almost always). Each score on the child report receives a score of 0 (not at all), 2 (sometimes), or 4 (a lot). Final transformed scores range from 0-100 with higher scores indicating better health-related quality of life.

The CAHPS CCC is an 81-item questionnaire that provides information on parents' experiences with their child's health care and gives a general indication of how well the health care meets their expectations. Five CCC-specific results are calculated for each population: 1) access to specialized services, 2) family-centered care: personal doctor who knows the child, 3) coordination of care for children with chronic conditions, 4) access to prescription medication, and 5) family-centered care: getting needed information.
