Objectives Discuss the role of the Primary Care Provider in developmental surveillance and screening Review the administration and interpretation of the most widely used screening tools Develop action steps for positive screen results Discuss barriers in various practice settings
Leading Causes of Limitation due to Chronic Conditions in US Children 1.Speech problems 2.Learning disability 3.ADHD 4.Other emotional, mental and behavioral problems 5.Other developmental problems 6.Asthma or breathing problems
Developmental Delay 12-16% of U.S. children About half will not be identified before kindergarten Association between disabilities and poorer health status
The Mandate Mandate for early identification and intervention for children with developmental disabilities Social Security Act, Title V Individuals with Disabilities Education Improvement Act (IDEA)
Impact of Early Intervention Increased academic achievement Increased adult employment rates Decreased criminality
Definitions Surveillance – Process of recognizing children who may be at risk Screening – Use of standardized tools to identify and refine that recognized risk Evaluation – Complex process aimed at identifying specific developmental disorders
Surveillance Parental concern – Developmental and behavioral concerns Documenting developmental history – Delayed milestones and deviations or dissociation, regression Accurate provider observations Identifying risk and protective factors – Environmental, genetic, biological, social and demographic factors Recording the process and findings
Surveillance Clinical judgment alone inadequate and insensitive Checklists and clinical observation has poor sensitivity Aylward showed that physician impression alone would have missed 45% of children eligible for early intervention
AAP Recommendations American Academy of Pediatrics – Surveillance at well-child visits – Standardized screening at 9, 18, and 24 or 30 month visits – Standardized screening when delay is suspected Based on substantial evidence demonstrating accuracy of several tools in research settings
Additional Organizational Statements USPSTF and AAFP – Insufficient or inconsistent evidence to recommend for or against routine use of brief, formal screening instruments (evidence rating C) Study design issues – Limited studies with general population samples – Lack of use of a criterion measure – Small sample sizes – Conflicting results between studies
Broad Screening Tools Address all developmental domains – Motor skills: fine and gross – Language & communication – Problem solving/adaptive behavior – Personal-social skills Should be culturally and linguistically sensitive Sensitivity and specificity levels of 70-80% are acceptable for developmental screening
Screening Tools A variety of screening tools to choose from Parent completed questionnaires most widely used –Ages and Stages Questionnaire –Parents Evaluation of Developmental Status
Ages & Stages Questionnaire (ASQ-3) Parent report questionnaire 5 developmental domains – 6 questions per domain Response options: yes, sometimes, not yet Provides total score and domain subscale scores
ASQ-3 Concerns Validated in mostly high risk populations Validity varies widely between populations – Age, language, country, sample size, risk status Poorer sensitivity in recent Canadian community sample – Very high SES sample
Parents’ Evaluation of Developmental Status (PEDS) Parent report questionnaire 10 questions – 2 general questions – 8 developmental domain questions Single form for all ages Responses: no, yes, a little Overall risk based on predictive versus non- predictive items
Limbos et al 334 children aged months Recruited from 80 primary care providers Completed screening with ASQ and PEDS Completed evaluation with adaptive, speech- language, and cognitive functioning scales

9 Month Well Visit No scheduled vaccines Rapid development – Motor skills – Early language skills – Social and nonverbal communication If practices have eliminated this visit, screen at 12 months
18 Month Well Visit No new vaccines Communication & language delays typically evident by this visit Mild motor delays undetected at 9 months typically are apparent Early intervention available for all domains at this age
30 Month Well Visit Goal of a focused visit on development Still time for state early intervention programs Now part of Bright Futures recommendations
Autism Screening Recommended schedule – 18 months – 24 months Modified Checklist for Autism in Toddlers (M-CHAT-R/F) – For use from months – 20 questions 0-2 continued surveillance, re-screen at 24 months 3-7 follow-up interview 8-20 refer for evaluation
Importance of the Follow-up Interview Follow-up interview – Follow-up questions for those items missed on the M-CHAT-R – 2 items of concern prompts referral Increased specificity from 95.5% to 99.3%
Are Separate Screening Tools Needed? Pinto-Martin et al. – 2-step screen with PEDS then M-CHAT – Positive PEDS 16% with positive M-CHAT – Negative PEDS 14% with positive M-CHAT YES! – ASD-specific tool for all children in conjunction with regular standardized developmental screening
Results of Screening Does not result in diagnosis Identifies variances from same-age norms Repeated and regular screening more sensitive that a single screening If surveillance or screening indicate developmental concern, sooner follow up and/or referral is indicated
Action Steps Early intervention services – BabyNet and ChildFind Referral for evaluation – Developmental-Behavioral Pediatrics, Psychology – Specific therapies – Audiology – Referral for STAT for autism concerns (24-36 mo)
Early Intervention Services Diagnosis not needed for referral Can be referred while awaiting evaluation Provide limited evaluation services – Further developmental & medical evaluation is typically needed Provide in-home therapies
Barriers Only 23% of primary care clinicians use standardized screening tools Time constraints – Cited by 82% of providers in a recent study Competing clinical demands Cost burden Staff requirements Lack of consensus on tools Insufficient training and expertise
Implementation AAP Task Force on Mental Health – Toolkit to aid implementation efforts Implementation steps – Ready the practice – Identify resources – Establish office routines for screening – Track referrals – Seek payment – Foster collaboration
Reimbursement – developmental testing, limited – Multiple units can be billed – Not covered by some private insurance providers Reimburses for review and interpretation of the screening tool
The Take Away Surveillance alone is not enough Screening is feasible in the primary care setting Repeated and regular screening is more likely than a single screening to identify problems Early intervention can significantly improve outcomes
