2 Priority of documenting childhood disability: 1915 “ during the third or fourth month, the most important acquisition being the power of balancing the head on the shoulders; the absence of this power at this stage was one of the earliest signs of mental deficiency” (Forsyth, 1915, British Medical Journal, p. 535)

3 Overview Present overview of ICF version for children and youth (ICF-CY) Identify different uses of the ICF-CY Review guidelines for coding Illustrate coding applications for different uses Clinical Educational Data management Statistical/ Research Identify continuing issues in the implementation of the ICF-CY

5 Need for ICF-CY éFunctioning, Activities, Participation & Environments different é from those of adults

6 Why is there a need for an ICF for children & youth? Nature and form of functioning in children different from that of adults Main volume of ICF lacking precursors of adult characteristics Child as a “moving target” in classification of function Indicators of functional risk factors crucial for prevention and early intervention ICF version for children and youth provides continuity of documentation in transitions from child to adult services

9 Guidelines for development of the ICF-CY Development of ICF-CY guided by relevant research and theory Structure ICF main volume maintained Inclusion/exclusion criteria expanded New content added to unused codes at 4, 5 and 6 character level Formats to highlight applications relevant to children

10 Central concepts from theory and research guiding ICF-CY development Development and Disablement as parallel processes- Changes in functions, activities and participation of child reflecting: Role of environment (transactional model) Child in context (Ecological systems theory) Development (Similar sequence/similar structure) Behavioral Regulation & organization Mediating role of Temperament/behavioral style Timing and maturation (Developmental delay)

15 General coding rules: annex 2 ICF A. Select an array of codes to form an individual’s profile B. Code relevant information- always in the context of a known or presumed health condition C. Code explicit information- the basis for coding must be explicit information D.Code specific information- code at the most specific level possible (1, 3, 4 or 5 character levels)

16 Criteria for qualifiers Form of Qualifier ICF Manual (problem= scale of difficulty in %) ICF-CY (std dev value< mean and/or % of population with problem) Rating/ Descript./ % of difficulty % of population 0-none ( 0-4%) 1-mild ( 5 -2 4%) 2-moderate (25-49%) 3-severe ( 50-95%) 4-complete ( 96-100%) 0-none < -1.0 sd (68%) 1-mild -1. -1.5sd (22%) 2-moderate 1.5-2.5 sd (6%) 3-severe 2.5-3.0 sd ( 3.0%) 4-complete 3+sd (1.0 %)

17 Ethical guidelines in use of ICF: annex 6 Respect and confidentiality Respect inherent value and autonomy of individual Never use to label individuals Use with full knowledge, cooperation and consent of person or advocate ICF codes treated confidentially Clinical use of the ICF Explain purpose to individual or advocate Opportunity for individual or advocate to participate ICF used holistically (limitation in physical/social context) Social uses of ICF information Used in collaboration with individuals or advocates ICF information use toward social policy- change ICF not used to deny rights Recognize individual differences

18 Classification applications of ICF-CY A common, universal language shared across disciplines and service settings A taxonomy for documentation of child functioning in: assessment intervention outcome measurement A framework for specifying the Child, the Environment and the Interaction in child- environment interaction

19 Child Physical and Mental function & structure Environment Availability & accessibility of physical, social, & psychological elements ICF-CY: documenting Child-Environment Interaction

20 Child Body Function and Body Structure (intact- impaired) Environmental Factors (Barriers - Facilitators) <--Interaction  ICF-CY: documenting Child-Environment Interaction Participation (Full to restricted) Activity (Complete to limited )

21 Classification applications of ICF-CY Standard for documentation of child rights-UN Convention on the Rights of the Child Framework for integrating interdisciplinary work Profiling functions for planning individualized interventions Documenting clinical features of childhood health conditions & diagnoses Resource in data management Intervention and outcome markers in education Variables for statistical and research work

22 ICF: Framework for interdisciplinary work Health Condition (disorder/disease) Body Structures & Functions Activities (activity limitation) Participation (participation restriction) Environmental PersonalFactors

23 ICF-CY: General steps in coding 1. Define the information available for coding and identify whether it relates to the domain of Body Functions, Body Structures, Activities/Participation or Environmental Factors. 2. Locate the chapter (4-character code) within the appropriate domain most closely corresponding to the information to be coded. 3. Read the description of the 4-character code and attend to any notes related to the description. 4. Review any inclusion or exclusion notes that apply to the code and proceed accordingly.

24 ICF-CY: General steps in coding 5. Determine if the information to be coded is consistent with the 4-character level or if a more detailed description at the 5- or 6-character code should be examined. 6. Proceed to the level of code that most closely corresponds to the information to be coded. Review the description and any inclusion or exclusion notes that apply to the code. 7. Select the code and review available information for assigning a value for the universal qualifier that defines the extent of the impairment, functional limitation, participation restriction (0=no impairment/difficulty to 4= complete impairment/difficulty or environmental barrier (0=no barrier to 4=complete barrier) or facilitator (0=no facilitator to+ 4=complete facilitator)

25 ICF-CY: General steps in coding 8. Assign the code with the qualifier at the 2nd -, 3rd - or 4th-item level. For example, d115.2 (moderate difficulty in listening). 9. Repeat steps 1-8 for each manifestation of function or disability of interest for coding and where information is available 10. Parents and consumers may participate in the process by completing age-appropriate inventories that allow specific areas of functional concern to be highlighted, but before full evaluations and codes are provided by professionals or a team of professionals.

26 Case: 10 year old boy T is a ten-year-old boy who was referred to a clinic for an evaluation after experiencing pervasive academic difficulties in the previous two years of school. On the basis of observation, it is clear that he has significant problems in concentration on academic tasks and is highly distractible. His parents report that T is “on the go” all the time and doesn’t seem to listen. According to his parents and teachers he has difficulty keeping still for any length of time in tasks at home and at school. At the present time, this means that he has trouble completing assigned work in the classroom.

27 Case: 10 year old boy He has particular difficulties remembering material he has studied. He is currently failing all of his academic classes and his performance in reading and writing is at the second grade level. He also shows difficulties adjusting to social situations involving other children. At school as well as at home, T’s teacher and parents are concerned about his high level of activity and the fact that he doesn’t seem to be able to think before he acts. This is evident in his social behavior when he fails to wait for his turn in games and sports and at home when he rides his bicycle into a busy street without looking.

28 Case: 10 year old boy A number of different interventions have been tried to help T perform in the classroom, but these have not resulted in improved performance. While the family has been reluctant to consider medication, T was recently seen by his pediatrician and Ritalin has been prescribed for his high level of activity. In conjunction with the medication trial, the school is designing an education support plan.

29 Case: 14 year old J is a 14 year-old girl living with her parents in a small town. She has severe asthma which was detected at a very young age. In addition to heightened response to specific allergens, J’s asthmatic attacks are also triggered by exercise, cold air and when she feels anxious. These attacks last 1-2 hours and occur several times a week. She is currently prescribed a bronchodilator and is to use a nebulizer prophylactically. In the last year, however, J is often inconsistent in following the medication regimen with the result that acute episodes are occurring more frequently.

30 Case: 14 year old From the time she was enrolled in a preschool program to the present, J’s school attendance has been marked by frequent absences. The result has been that her achievement has been consistently poor, and while she has not failed any grades she is falling farther and farther behind her peers. At the present time, she is in the eighth grade in the local middle school. Because of frequent absences, J has not developed a consistent group of friends at school.

31 Case: 14 year old Further, because exercise triggers acute episodes, she has not participated in the physical education program at school and is not engaged in any other regular physical activity. A result is that she has experienced a significant weight gain in the last year. J reports feeling different from others increasingly isolated from her peers. Her parents are becoming very concerned about her physical and emotional health and are seeking consultation from their medical doctor.

46 Assessment inventory in Early intervention Early intervention program for children birth to 3 in Georgia Adaptation of 0-3 questionnaire developed for field trials of ICF-CY Selected codes from Activities/Participation and Environmental Factors Very favorable response by parents to format and developmental content Resulted in raised awareness of environmental factors not considered previously

47 Statistical & research applications Established inter-rater reliability in assigning ICF codes: children with disabilities using existing developmental measures (Ogonowski, et al., 2004); and children with special health care needs structured interview (Kronk, et al., 2005) ICF framework for setting goals for children with speech impairments (McLeod & Bleile, 2004).

48 Statistical & research applications: Canadian national survey data Measuring chronic health conditions and disability in children in Canadian national survey data (McDougall & Miller, 2003). Review of 4 disability and 5 health surveys for extent of coverage of health conditions (ICD-10) and disability (impairment, activity and participation restrictions- ICF) Two independent reviewers

49 Statistical & research applications: Canadian national survey data Extent of coverage of domain Disability SurveysHealth Surveys Health conditions67%39% Impairments50%55% Activities/ Participation 64%84% Environmental Factors 60%68%

50 Statistical & research applications: Canadian national survey data Participation and Activity Limitation Survey and National Longitudinal Survey for Children and Youth provided best coverage of ICF activity limitations PALS provided most comprehensive coverage of need for/use of Assistive technology Areas of limited coverage in surveys: Mental functions and some body functions; Personal care and domestic life; natural environment changes, attitudes and policies.

51 Research application: joint use of ICF and ICD-10 to code reasons for eligibility in early intervention What is the nature and prevalence of functional characteristics of young children (< 3 years) in early intervention ? Lack of information due to the fact that existing eligibility data assigned children to 3 general categories (developmental delay, established medical conditions, risk status) Data drawn from National Early Intervention Longitudinal Study (NEILS) a weighted sample of children and families from the time they enter early intervention through at least kindergarten.

52 NEILS Enrollment Sample Information collected on 5,668 children Descriptors accompanying the child’s eligibility status were coded 445 different classification entries were organized under 4 categories and 29 subcategories An average of 1.5 descriptors provided for each child (range 1 -11)

53 Algorithm for NEILS coding system Classification A conceptual framework with 4 major categories (I-IV) and 29 sub-categories (A-BB): I. Impairment of body functions or structure (A-H) II. Limitations of activity or performance (I-P) III. Diagnosed health conditions (Q-X) IV. Environmental factors (Y-BB) Method: Descriptors on enrollment forms were coded to the closest ICD-10 or ICF codes

54 ICF: Framework for NEILS coding system CATEGORY III: Health Condition (disorder/disease- ICD dx) CATEGORY I: Body Structures & Functions CATEGORY II: Activities (activity limitation) CATEGORY II: Participation (participation restriction) CATEGORY IV: Environmental PersonalFactors

60 Revisiting a priority “..classification is serious business. Classification can profoundly affect what happens to a child. It can open doors to services and experiences the child needs to grow in competence, to become a person sure of his worth, and appreciate the worth of others, to live with zest and to know joy”. (Classification of Children, Hobbs, 1975; The futures of children, Hobbs, 1975)
