It employs an open, prospective, multicentric, population-based cohort approach. This report aims to describe the methodology employed to establish and manage the programme, details regarding follow-up procedures, baseline characteristics of the included infants, and highlights new research opportunities emerging from the &#8220;<em>Suivi des Enfants Vuln\u00e9rables d&#8217;Ile-de-France<\/em>&#8221; (SEV-IDF) programme.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Participants:<\/strong> The programme aims to (1) detect developmental anomalies early, (2) improve prevention using standardised data, (3) optimise follow-up care and (4) support multidisciplinary research.Eligible participants are infants alive at discharge from the 59 maternities with a neonatal unit of the \u00cele-de-France (IDF) region (France). A network of 567 trained physicians monitors the children&#8217;s development at 4 months, 1 and 2 years of corrected age, and 3, 4, 5, 6 and 7 years of age. Collected data include sociodemographic, pregnancy and neonatal characteristics, and standardised child development scores.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Findings to date:<\/strong> The programme enrolled 21 175 participants between 2016 and 2023, with 16 461 (77.7%) having a gestational age less than 33 weeks, 1916 (9.0%) others having VLBW, 1525 (7.2%) having encephalopathy and 1273 (6.0%) having another severe birth anomaly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Future plans:<\/strong> The collected data will enable the SEV-IDF scientific committee to describe high-risk infants in the IDF region, design evidence-based campaigns to improve the quality and effectiveness of the follow-up as well as conduct research on developmental anomalies in these high-risk infants. Ongoing research currently focuses on anticipating loss to follow-up and early detection of developmental anomalies.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>BMJ Open. 2025 Jul 7;15(7):e089953. <\/p>\n","protected":false},"featured_media":0,"template":"","class_list":["post-8732","publication","type-publication","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.1 -
