4Background
- 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.
5Long Term Goal
- To develop a clinically useful predictive
distress profile that can be used to identify
interventions appropriate to individual family
needs
6Predicting Childrens Response to Distraction
from Pain orDistraction Intervention Grant (DIG)
NIH/NINR 1 R01 NR05269 Funding from 2002-2007
7DIG Purpose
- To identify predictors of child response to a
peripheral IV insertion when a parent provides
distraction
8DIG 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

11Predictors 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)

15CPMD 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.
16Computerized Predictive Model of Distraction
17Data 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 -

18Predictive 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

20Designing 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 - Links to central secured server

out as expected? - Development of the Distraction Coaching Index

- Quality
- Video taped and scored later
28Genetics 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)

30Salivary Cortisol Norms for Children
31Cortisol Responsivity ADHD
Note Expect cortisol to be higher on the clinic
(stressful) day as it was in the Non-ADHD sample.
32Implications 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 -
