Effect of the IBAIP in Preterm Infants Neurodevelopment

Study Overview
=================
Brief Summary
-----------------
Mortality in very preterm infants has decreased significantly over the past twenty years. However, neuromotor, behavioral and cognitive development disorders are more common in these children born before 33 weeks of gestation as compared to term born infants. These neurodevelopmental disorders include difficulties with self-regulation, tone, posture or poor quality movements as well as inadequate responses to sensory simulation. Post-hospital discharge follow-up and interventionsof children born very preterm ares very heterogeneous in France. They are mainly carried out in a rehabilitation center, based on caregivers whereas IBAIP is carried out at home and family centered. Early interventions during hospitalization or after discharge appear potentially of great interest in improving the neurodevelopemental outcome of the very preterm infants. Several early interventions have been developed and evaluated in other countries. These interventions are designed to be used early in life, mainly during the first 3 years of life, and are based on brain plasticity and intense synaptogenesis during this period of life. The IBAIP (Infant Behavior Assessment and Intervention Program) was developed on the same theoretical foundations as the NIDCAP (Neonatal Individualized Development Care and Assessment Program). IBAIP consists of providing the child and his family with an intervention, at home, starting just before hospital discharge up to a 6 months corrected age. .The aim of IBAIP is to support developmental functions including infant's self-regulation and focus on improving the responsiveness of parents' infant interactions.

Detailed Description
-----------------
This program consists of providing intervention, by a IBAIP trained and certified healthcare professional, with the child and his family, starting a few days before hospital discharge and continuing at home until the corrected age of 6 months. It focuses on the child's behaviors and consists of assisting the family in its interactions with the child so that these are adapted and responsive to the child's development needs over time through repeated interventions. A cluster randomization will be used meaning the centers are randomized, not the individual patients. The centers will be randomized before the inclusion of patients in order to allow the physiotherapists or psychomotor therapists to be trained and certified to the IBAIP before the start of the trial. Visit 1: Upon discharge from hospital, follow-up as part of standard care (control group) with at least 1 medical consultation per month during the first 6 months or according to the IBAIP program (experimental group) with one intervention in the week before discharge from hospital and at home after hospital discharge, with1 session once a month up to 6 months corrected age (i.e. 6 to 8 sessions) in addition to standard care. Visit 2: At 6 months corrected age, parents' response to the PSI (Parenting Stress Index) questionnaire. Visit 3: At two years corrected age : Assessment of the development quotient obtained on the BSID-III scale during a consultation with a neuro-psychologist. Parents' response to the PSI (Parenting Stress Index) questionnaire Parents' response to the ASQ (Ages and Stages Questionnaire

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: IBAIP Group<br>Children benefiting from assessment and intervention providing by a healthcare professional (physiotherapist or psychomotor therapist) trained and certified for IBAIP. This care will take place upon discharge from the hospital at the rate of one session per month for 6 months. The sessions will take place in the presence of at least one of the parents and at home. These children will also benefit from standard follow-up (medical follow-up, paramedical or specialized medical support depending on the development and needs). | Other: IBAIP : Infant Behaviour Assessment and Intervention Program<br>* The IBAIP intervention program consists of providing an intervention with the child and their family, at home, upon discharge from hospital and up to a corrected age of 6 months. Interventions therefore take place at the early stage of the child's brain development. The intervention is performed by a IBAIP-trained and certified physiotherapist or psychomotor therapist trained , at the rate of one session per month over a period of approximately 6 to 8 months (6 months of corrected age). The session takes place in the child's usual living environment, at home, in the presence of at least one of the parents. It focuses on the child's behaviors and consists of assisting the family in its interactions with the child so that these are adapted and responsive to the child's development needs over time through repeated interventions.<br>Other: Ages and Stages Questionnaire (ASQ)<br>* Global development screening tool<br>Other: Parenting Stress Index (PSI)<br>* Index used to detect difficulties sufficiently significant that they might require psychosocial intervention<br>Other: Bayley Scales of Infant and Toddler Development (BSID-III)<br>* This test was designed to measure the development of infants / young children.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To assess the effect of the Infant Behavior Assessment and Intervention Program Program (IBAIP) in very preterm infants (< 33 weeks of gestation) on neurodevelopment at the corrected age of 2 years | Patient neurodevelopment will be assessed using the Bayley Scales of Infant and Toddler Development (BSID-III) scale. This test studies the different notions of development: cognitive, language, motor skills, socio-emotional, behavioral, communication and autonomy. | 2 years of corrected age | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To assess the effect of IBAIP on the 5 sub-scores of BSID-III: cognitive, language, motor, socio-emotional and behavioral adaptive | The BSID-III scale can be analyzed at the level of each of these subscales. The different scores obtained allow us to identify precisely at what level the effect on neurodevelopment was the most significant. | 2 years of corrected age | 
| To assess the effect on the stress level of mothers and fathers | To assess through the response to the Parental Stress Index. This questionnaire consists in 120 items using a 5-level Likert scale. It allows the assessment of life stress score, parental stress and child stress. | 2 years of corrected age | 
| Parental assessment of psychomotor development | Ages and Stages questionnaire completed by the parents to assess the child's neurodevelopment in 5 areas (fine motor skills, gross motor skills, communication, problem solving, individual or social skills). | 2 years of corrected age |
