Preterm Infants Born to Homeless Mothers.

Study Overview
=================
Brief Summary
-----------------
In recent years, the number of homeless patients who are accommodated by the SAMU social has increased. These patients are in a situation of financial, but also often social and psychological precariousness. The literature already shows us that precariousness and homelessness are a risk factor for prematurity, but also for the patients themselves, a risk of more frequent recourse to emergency services and of late consultation for advanced pathologies. The objective of this study is to evaluate the fate and quality of medical follow-up of children born very premature (≤33SA) to homeless mothers.

Detailed Description
-----------------
The hospital of Pontoise is the largest maternity hospital in the department (Val d'Oise, 95) with 4449 births in 2021. It has a type 3 neonatal intensive care unit where approximately 150 premature babies under 32 weeks of age are hospitalized each year, including 80 premature babies under 28 weeks of age. These children require a specific and prolonged follow-up after hospitalization, including medical consultations to evaluate their neurodevelopmental development, but also the prevention of RSV infection (Respiratory Syncitial Virus). In recent years, the number of homeless patients who are accomodated by the SAMU social has increased. These patients are in a precarious financial, but also often social and psychological situation. The literature already shows us that precariousness and homelessness are a risk factor for prematurity, but also for the patients themselves, a risk of more frequent recourse to emergency services and late consultation with advanced pathologies. The aim of this study is to evaluate the fate and quality of medical follow-up of children born very premature (≤33SA) to homeless mothers, by answering the following questions: What about the follow-up of their very premature child? How does the department organize itself to ensure optimal follow-up for these patients?
