Background
  • Procedural pain is a major source of distress in
    children.
  • Distraction- diverting a childs attention away
    from the medical procedure and focusing on other
    things- can decrease child distress with
    procedures.
  • We can teach parents to use distraction to
    decreases child distress.

5
Long Term Goal
  • To develop a clinically useful predictive
    distress profile that can be used to identify
    interventions appropriate to individual family
    needs

6
Predicting Childrens Response to Distraction
from Pain orDistraction Intervention Grant (DIG)
NIH/NINR 1 R01 NR05269 Funding from 2002-2007
7
DIG Purpose
  • To identify predictors of child response to a
    peripheral IV insertion when a parent provides
    distraction

8
DIG Methods
  • Design Random assignment to control or
    experimental groups
  • Sample 542 children, 4-10 years old, planned IV
    insertion
  • Intervention
  • Educational material discussion
  • Video
  • Distractors

Predictors and Outcomes
  • Predictors Child, parent, procedure variables
  • Genotype
  • Child Outcomes
  • Behavioral Observation Scale of Behavioral
    Distress-Revised (OSBD-R) (Elliott et al, 1987
    Jay et al, 1983 Jay Elliott, 1984)
  • Biological Salivary cortisol levels (Kirschbaum
    Hellhammer, 1994)
  • Self Perception of Pain Oucher Scale (Aradine et
    al., 1988 Beyer Aradine, 1988)
  • Parent Perception of Child Distress (Kazak et al,
    1996)

CPMD Study Purpose
  • The purpose is to use the Computerized
    Predictive Model for Distress/Distraction (CPMD)
    to predict high, medium, or low risk for distress
    groups and to test the level of distraction
    intervention appropriate for each risk group.

Data Mining
  • searching for consistent patterns and
    relationships among data points based on analysis
    of a large set of data and turning those
    discovered relationships into a model. The
    model is then applied to other test cases to
    determine if the model will hold on new cases

Predictive Modeling Using Data Mining
  • All items identified with Data Mining were also
    identified by traditional regression
  • Identified specific predictive items rather than
    global instruments. For example
  • I feel anxious item rather than anxiety
    subscale of the STAI
  • My child never stops moving item rather than
    activity subscale on DOT
  • Items from DIG study244
  • Items in CPMD47

Designing the C Computer Application
  • Predicts risk for child distress with medical
    procedures
  • Tailors evidenced based interventions to the
    parent and child based on their responses to
    questions
  • Randomizes high, medium and low risk dyads to
    test interventions in next study

CPMD Methods
  • Design Randomized Clinical Trial
  • Subjects Children ages 4-10 having a scheduled
    IV (n 582)
  • Settings
  • UI Childrens Hospital
  • Blank Childrens Hospital
  • Cardinal Glennon SLU

23
CPMD Methods
  • Instruments
  • CPMD that includes elements of child, parent, and
    procedural variables
  • Genotyping
  • Outcomes
  • Behavioral (videotaping)
  • Biological (cortisol)
  • Oucher (included in CPMD)
  • Parent report (included in CPMD)

DIG Related Analyses
  • Distraction Coaching Index (DCI)
  • Genetics
  • EDNRA
  • Candidate genes for pain anxiety
  • Cortisol
  • Norms
  • ADHD

27
Distraction Coaching Index (DCI)
  • Treatment Integrity Is the intervention carried
    out as expected?
  • Development of the Distraction Coaching Index
    (DCI) (Kleiber et.al., Childrens Health Care,
    2007)
  • Frequency
  • Quality
  • Video taped and scored later

28
Genetics Results
  • Forty percent of subjects reported high pain
    (Oucher score 4-10) despite the appropriate
    application of topical analgesic.
  • Pain response did not differ by
  • Gender (?2 0.28, .5 lt p lt .7)
  • Type of topical anesthetic (?21.07, p0.301)
  • Ethnicity ( ?2 0.37, p0.54)

Salivary Cortisol Norms for Children
31
Cortisol Responsivity ADHD
Note Expect cortisol to be higher on the clinic
(stressful) day as it was in the Non-ADHD sample.

32
Implications for Practice
  • We can teach parents to use distraction.
  • Higher distraction quality is associated with
    less behavioral distress.
  • Children have pain despite topical anesthetics.
    There may be a genetic cause related to the EDNRA
    gene.
  • Normal cortisol levels and responsivity follow
    the pattern of adults. Children with ADHD have
    atypical cortisol responses.
  • Predictors of parent child responses can be
    used in practice
