U.S. National Survey ofChildren’s Health (NSCH) • Dates: 2003, 2007, 2011 • Conducted by: National Center for Health Statistics • Purpose: Produce estimates on the health and well-being of children, families, & their communities • Sample: Independent random-digit-dial (RDD) samples for all 50 states & the District of Columbia (DC) • Random selection: One child 0 – 17 years of age selected from each household with children to be the subject of the interview • Goal: Complete interviews for over 91,000 children nationally (goal: 1,700 completed per state & DC) • Respondent: Parent or guardian
NSCH Sponsor • Has primary responsibility for promoting and improving the health of U.S. women, children and families. • Provides leadership to improve the physical and mental health, safety and well-being of the MCH population • Administers block grants to state MCH agencies
Title V MCH Block Grants • The US federal government budgets more than $1 billion annually for MCH services • In order to be entitled to payments, states must use at least 30 percent of such payment amounts for services for children with special health care needs (CSHCN) • Why CSHCN? • CSHCN account for 42% of total medical care costs (excluding dental costs)
Definition of“Children with Special Health Care Needs” • “Children with special health care needs are those who have or are at increased risk for a chronic physical, developmental, behavioral, or emotional condition and who also require health and related services of a type or amount beyond that required by children generally.” (McPherson, Arango, Fox, et al., 1998)

Definition of“Children with Special Health Care Needs” • “Children with special health care needs are those who have ... a chronic physical, developmental, behavioral, or emotional condition and who also require health and related services of a type or amount beyond that required by children generally.” (McPherson, Arango, Fox, et al., 1998)

What is the CSHCN Screener? • A non-condition-specific, consequences-based method for identifying CSHCN, targeting Categories B and C • Designed in 1998-2000 by the Child and Adolescent Health Measurement Initiative (now at OHSU) • Developed through a national process involving physicians, state leaders, families, methods experts, and policymakers • Tested with parents of 36,000+ children during development phase • Several versions tested, leading to final version, which takes 1 minute for parents to complete • Data for more than 1 million children analyzed since 2000
The CSHCN Screener • Asks about five “common” consequences • Limitation of activities • Need for or use of prescription medication • Need for or use of specialized therapies • Above routine need or use of medical, mental health, or education services • Need for or receipt of treatment or counseling for an emotional, behavioral, or developmental problem (Bethell, Read, Stein, Blumberg, Wells, & Newacheck, 2002)
The CSHCN Screener • Two follow-up questions • Is this due to a medical, behavioral, or other health condition? • Is this a condition that has lasted or is expected to last 12 months or longer? (Bethell, Read, Stein, Blumberg, Wells, & Newacheck, 2002)
Key Features of CSHCN Screener • Based on parent report • Most amenable to uniform data collection • Short (1 minute to complete) • Costs per item are usually high in government surveys • Longer surveys threaten participation rates • Based on consequences rather than conditions • Condition checklists tend to be very long • Condition checklists are hard to analyze and interpret • Focus on consequences helps capture children with conditions not yet diagnosed or poorly recalled
Cross-Method Comparisons • Over 93% of identified CSHCN had at least one specific chronic health condition or problem, and most had two or more • Over 98% of identified CSHCN had some type of functional difficulty, as defined by the International Classification of Functioning (ICF)
Who is Identified by the Screener? • All or nearly all children with complex health conditions such as: • Cerebral palsy; cystic fibrosis; muscular dystrophy • Rare metabolic or genetic disorders • Mental retardation; developmental delay; autism • Sickle cell anemia; Down Syndrome; diabetes • Only those children whose asthma, ADHD, allergies, or other conditions result in: • Elevated service use, • Long-term use of prescription medicine, or • Limitations in functioning
Who is Missed by the Screener? • The CSHCN Screener is likely to miss children who have only: • Food or environmental allergies • Special diet (e.g., lactose intolerance) • Vision problems (e.g., amblyopia, colorblindness) • Developmental delays early in life • Some parents of children with speech problems, learning disabilities, developmental delay, and conduct problems report consequences but then say they are not due to “health conditions”
Data Source: NS-CSHCN, 2005-2006 Over-Identification? • Should ongoing need for only prescription medication be considered a special need? • Should children with only asthma or allergies be considered CSHCN?
Survey-Based Uses of the CSHCN Screener in the U.S. • National Survey of CSHCN (NS-CSHCN) • National Survey of Children’s Health (NSCH) • Medical Expenditure Panel Survey (MEPS) • Consumer Assessment of Health Plans Survey (CAHPS)

Why Might Prevalence Rates Differ Across Surveys? • Dates of data collection • Method of data collection and estimation • Mode • Sampling frame • Interviewers • Weighting methods • Sample size and sampling error • Method of identification • Respondent • Recall period • Question wording • Question ordering • Question context and introduction

The CSHCN Screener • Reliably identifies children requiring on-going medical and other health-related services • Can be used to stratify children into meaningful subgroups related to condition complexity • Is sensitive to health care practice patterns (such as those related to cultural differences) • Yields results that can be influenced by differences in survey administration • Provides a key health indicator that is related to the home environment and the well-being of children and their families
