The effects of different positions on neurodevelopment in preterm infants admitted in neonatal intensive care units: a systematic review protocol

Abstract

Introduction Preterm birth poses significant challenges to infant health, with neurodevelopmental outcomes often affected. In the Neonatal Intensive Care Unit (NICU), positioning strategies are commonly employed with the aim of mitigating adverse effects and promoting neurodevelopment in preterm infants. However, the evidence regarding the impact of different positions on neurodevelopmental outcomes remains heterogeneous and inconclusive. Objective The aim of this systematic review is to evaluate the effects of different positioning strategies on neurodevelopmental outcomes in preterm infants admitted to Neonatal Intensive Care Units (NICUs). Methods A comprehensive search will be conducted in electronic databases including PubMed, MEDLINE, EMBASE, and Cochrane Library. To comply with the established guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework, the systematic review will be conducted to identify relevant studies published up to the date of the search. This systematic review protocol has been registered in PROSPERO to ensure thorough and transparent reporting of the search process, synthesis of findings, and analysis methods. Discussion In the context of preterm infants admitted to Neonatal Intensive Care Units (NICUs), the discussion surrounding the effects of different positions on neurodevelopmental outcomes is multifaceted and warrants careful consideration. Variations in study methodologies, including sample sizes, outcome measures, and follow-up durations, underscore the need for standardized approaches to facilitate comparison and synthesis of findings. The heterogeneity in reported outcomes, ranging from cognitive and motor development to sensory processing, highlights the complexity of neurodevelopmental assessment in this population and emphasizes the importance of comprehensive evaluation frameworks. Through rigorous synthesis and analysis of existing literature, our protocol aims to contribute meaningful insights that can drive future research agendas and enhance neurodevelopmental outcomes for this vulnerable population.
