Overview aap policy l.jpg
Overview - AAP Policy Problems

AAP Committee on Children with Disabilities recommends routine standardized developmental and behavioral screening

Pediatrics Vol. 108 No. 1 July 2001


Terminology l.jpg
Terminology Problems

Surveillance

Vs.

Screening

Vs.

Assessment


Differences among surveillance screening and assessment l.jpg
Differences Among Surveillance, Screening, and Assessment Problems

  • Surveillance: A flexible, continuous process whereby professionals performed skilled observations of children during provision of health care

    • Eliciting and attending to parental concerns

    • Obtaining relevant developmental history

    • Making accurate and informative observations of children

    • Sharing opinions and concerns with other relevant professionals


Differences among surveillance screening and assessment6 l.jpg
Differences Among Surveillance, Screening, and Assessment Problems

  • Screening: Dependable, quick, flexible, and brief ‘sorting’ strategy that distinguishes those children who probably have difficulties from those who probably do not

  • Screening applied to asymptomatic children to preemptively identify problems that would not otherwise be detected


Differences among surveillance screening and assessment7 l.jpg
Differences among Surveillance, Screening, and Assessment Problems

  • Assessment: In-depth, comprehensive examination of relevant domains


Current practices in developmental behavioral screening l.jpg
Current Practices in Developmental/Behavioral Screening Problems

  • Nearly all providers use surveillance

  • Many providers use developmental checklists

  • Many providers use trigger questions to promote discussion

    • Guidelines for Health Supervision (AAP)

    • Bright Futures (MCHB/AAP)

  • 15-20% of pediatricians use screening tests routinely


Screening strategies and goals l.jpg
Screening Strategies and Goals Problems

  • Screening strategies

    • Clinician questions; parent-completed screening questionnaire; physician-completed check sheet

    • Condition under consideration must be important, common, diagnosable, treatable

  • Screening goals

    • Use of multiple sources of information

    • Result should be concern, but not conclusions; a path to more in-depth assessment

    • Consider family and environmental contexts


Why screen and refer l.jpg
Why Screen and Refer? Problems

  • Facilitates access to intervention services

  • Benefits patients - Studies of impact of interventions reveal

    • better intellectual, social, and adaptive behavior

    • increased HS graduation, employment rates

    • decreased criminality and teen pregnancy

  • Improves patient/family satisfaction

  • Satisfies federal/legal requirements


Detection rates without tools with tools l.jpg

20% of mental health problems identified Problems

(Lavigne et al. Pediatr. 1993; 91:649-655)

30% of developmental disabilities identified

(Palfrey et al. JPEDS. 1994; 111:651-655)

80-90% with mental health problems identified

(Sturner, JDBP 1991; 12:51-64)

70-80% with developmental disabilities correctly identified

(Squires et al., JDBP 1996; 17:420-427)

Detection RatesWithout Tools With Tools


Cost effective l.jpg
Cost Effective Problems

  • Benefits child

  • Reduces future health care costs (cost of early treatment is substantially lower than later treatment)

  • Saves medical resources


Good patient care l.jpg
Good Patient Care Problems

  • Parents want and expect support on child development

    • Commonwealth Fund survey

    • Parents are least satisfied with extent to which their children’s regular doctors helps them understand their children’s care and development

  • Screening can encourage parent involvement and investment in child’s health care


Federal legal requirements l.jpg
Federal/Legal Requirements Problems

  • Individuals with Disabilities Education Act (IDEA) 1975 (Amended in 1997 and 2004)

    • IDEA secures patients’ right to appropriate early intervention services, which state agencies must provide

  • Healthy People 2000 & 2010 Goals

    • Ensure that children enter kindergarten ready to learn

    • Use screeners to identify delays and refer for services


What to expect from screening glascoe 2000 l.jpg

11% - high risk of disabilities; need further evaluations Problems

26% - moderate risk of disabilities; need 2nd level screening and vigilance

20% - low risk of disabilities; need behavioral guidance

43% - low risk of disabilities; need routine monitoring

What to Expect from Screening (Glascoe 2000)


Screening challenges providers l.jpg
Screening Challenges: Providers Problems

  • Lack of education on tools and their use

  • High expectations for normal development

  • The “wait and see” approach

  • Continued reliance on observations

  • Failure to trust screening tests or results

  • Reliance on poor quality or homemade tools


Screening challenges providers17 l.jpg
Screening Challenges: Providers Problems

  • Lack of time

  • Lack of staff

  • Inadequate reimbursement

  • Lack of parent acceptance of delay or problem


Screening challenges parents l.jpg
Screening Challenges: Parents Problems

  • Parent recall is often inaccurate

  • Parent reports rely on current descriptions of child’s behavior and skills

  • Parents may face personal challenges


Pitfalls of screening l.jpg
Pitfalls of Screening Problems

  • Not screening until a problem is observable

    • If the problem is obvious, referring is the correct response

  • Ignoring screening results

    • Good screens make correct decision >70 - 80% of time

  • Relying on informal screening methods

    • Discriminating between adequately developed and problematic levels of skills requires careful measurement

  • Using a screening measure not suitable for primary care

  • Assuming services are limited or nonexistent


Rewards of screening l.jpg
Rewards of Screening Problems

  • Parents are reservoirs of rich information

  • Screening becomes a teaching tool for parents and health care professionals

  • Screening improves relationships

  • Screening structures observations, reports, and communication about child development

  • Using well-tested, standardized screening tools reduces unreliability of parent reports


Overview summary l.jpg
Overview Summary Problems

Developmental/Behavioral Screening is:

  • Recommended by AAP

  • Different than surveillance

  • Beneficial to children and practices

  • Underutilized

  • Challenging but rewarding to implement



Parent report screening tools features l.jpg
Parent Report Screening Tools – Features Problems

  • Easier than other measures for pediatricians to use

  • Can be administered to parents in the waiting room, sent home with appointment reminders, or conducted by telephone or during an in-office interview


Parent report screening tools examples l.jpg
Parent Report Screening Tools – Examples Problems

  • Parents’ Evaluation of Developmental Status – PEDS (Glascoe)

  • Ages and Stages Questionnaires – ASQ (Bricker and Squires)


Ex parents evaluations of developmental status peds glascoe 1997 l.jpg

Management after screening evidence based decision making l.jpg
Management After Screening: Evidence-based Decision-Making Problems

  • When and where to refer

  • When to screen further

  • When to provide behavioral/ developmental guidance and promotion

  • When to observe vigilantly

  • When reassurance and routine monitoring are sufficient


Referral options l.jpg
Referral Options Problems

  • General

  • Prevention Programs and Resources

  • Early Intervention – for suspected delay or qualifying condition

    • Birth to age 3

  • Education - educational and therapeutic services mandated by Individuals with Disabilities Education Act (IDEA)

    • Age 3 to 21


Concluding messages l.jpg
Concluding Messages Problems

  • "Flu model" does not apply to developmental and behavioral problems

  • Screen and screen again

  • Refer, refer, refer

    • Err in direction of referral rather than deferral

    • Children who are over-referred have below-average performance, increased psychosocial risk
