AIM

Establish a framework to enable neurodevelopmental follow up to be performed in all North Central London Network infants born at < 30 weeks gestation or < 1000grams and other high risk infants – HIE, seizures, neonatal stroke etc

To provide anticipatory guidance

To ensure early intervention

To provide data for planning service provision and to assist the neonatal units

To provide data for research studies including TRPG/SEND outcomes groups

Expected outcomes of the follow up

programme

Co-ordinated programme across several hospitals in our network

Systematic, standardised and reliable programme

Results on a database for further study and reported nationally

Results also reported in writing to all those involved in the care of the child and the parents

Outcome data would be used to:

Facilitate benchmarking within a population based group

Improve clinical care

Facilitate research

Improved parent and family satisfaction in the community setting

Why Who What

?

High risk preterm and

term babies

Babies with high risk of neurodevelopment problems

because of biological disadvantage

Babies <30/40

Babies <1000 grams

Term infants with

HIE

Other neurology

or abnormal

MRI

Why Who What

?

Aim:

To provide a high quality , standardised, equitable and accessible local service

To improve long term outcome of survivors of NICU at high risk of developmental problems

Provision of neurodevelopmental follow-up for at least 2 years corrected forms part of national recommendations for neonatal services - BAPM

Infants born preterm are at greater risk for developmental impairments than term peers

‘High prevalence low severity’

impairments

Rates of major disability have remained relatively constant whilst prevalence of milder dysfunctions increasing

Cognitive, behavioural and mild motor problems without major deficits are now the most dominant neurodevelopmental sequelae in children born preterm

Learning problems

Borderline to low IQ score

Attention deficit

Specific neuropsychologi

cal deficits affecting

visuomotor integration and

executive function

They occur in > 50% of

preterms with VLBW and

are often not in isolation

Include

Pathogenesis largely

unclear but includes

Lower gestational age Brain lesions such as

IVH

Periventricular haemorrhagic

infarction

PVL

Developmental disruptions include

diffuse white matter injury

Psychiatric disorders were significantly associated with cognitive impairment


EPICure study

After adjustment for IQ, studies have highlighted persistent problems with maths, oral-motor skills, verbal working memory and perceptual-motor and spatial-organisational difficulties.

This pattern of problems thought to be indicative of a disruption to global brain development

Imaging studies provide confirmatory evidence of reduced cortical volume, size and complexity in preterm populations.

Language and reading difficulties can be accounted for by general cognitive impairment

Specific deficits in maths may be a result of more specific impairment of regional brain areas

Maths abilities related to

Working memory

Executive function

Attentional control

Perceptual and visuo-spatial skills

All of which can be selectively impaired in preterm infants

Implications for intervention

Motor development plays an integral role in perceptional and cognitive development.

Research suggests that interventions targeted at:

Motor control

Executive functioning

Behavioural and emotional problems

may improve educational outcomes

Why Who What

?

The goals of Follow-up

Promote child health and well being

Enhance emerging competencies

Minimize developmental delays

Remediate existing or emerging disabilities

Prevent functional deterioration

To provide education & support to enhance family’s care giving skills & maximise infants developmental potential

Purpose of Follow-up


Opportunity to provide reassurance for families


Teach about development


Link families to other community based services when appropriate

•promote confident parenting and overall family functioning through the use of anticipatory guidance

Parent-infant

interaction

Various studies have indicated that more responsive, positive, warm

and sensitive parenting is associated with better developmental

outcome

Koldewijn et al showed

Infants who had received early intervention that paid specific attention to the infants self regulation and sensitive parent-infant interactions had a significantly better motor outcome at the age of 2 years.

Anticipatory Guidance what is it?

“Provision of information to parents with the expected outcome being a change in parent attitude, knowledge or behaviour”

Basic Principles of

interventions

Use anticipatory guidance

Coach parents to integrate motor activities into daily routines

Help infant to successfully experience a wide variety of sensory motor activities to learn and develop with the ‘just right’ challenge in mind

Provide the opportunity for play and progression in a variety of positions – avoid overuse of static ‘positioning

Coach parents – not just 45 minute therapist led therapy session

Early intervention for optimal outcomes with cognitive, motor and social emotional disorders

Support to Parents

Use anticipatory guidance to advise on suitable seating, baby walkers, TV, playing alone for long periods on mobile devices, etc

Positive feedback identifying all achievements no matter how small

Normalise parental role

(toys, clothes, shoes, car seat, high chair)

Excitement over “firsts”

(rolling, sitting, hands to feet, clapping)

Developmental Goals

Progress developmental milestones

(gross/fine motor, cognitive, social, language)

Monitor and assess tone

Age appropriate play activities

Follow-up Precautions

Majority of VLBW infants do not have CP.

Neuromotor development of preterm infant is different than that of a full term infant.

Infant test scores are not necessarily predictive but socioeconomic status is a powerful predictor.

Developmental outcomes change over time – sometimes for better and sometimes for worse

Families may not be ready to acknowledge the problems you see

Evidence for intervention:

Evidence on neural plasticity shows the developing brain is capable of being modified by both deleterious (e.g. early stress) and beneficial (e.g. enriched environments) experiences.

Sound neurophysiological basis for early intervention

Research has shown that reorganisation of an injured motor cortex is possible through therapeutic activities
