Systematic review of developmental care interventions in the neonatal intensive care unit since 2006

Area of Science:

• Neonatal Intensive Care Unit (NICU) care
• Developmental Pediatrics
• Evidence-Based Practice in Neonatology

Background:

• Premature infants face significant risks to neurodevelopmental outcomes.
• Neonatal intensive care unit (NICU) environments present unique challenges.
• Intervention studies aim to mitigate these risks and improve long-term development.

Purpose of the Study:

• To systematically review intervention studies targeting neurodevelopmental outcomes in premature infants.
• To analyze research methodologies and assess the effectiveness of various interventions.
• To provide recommendations for future research in NICU developmental care.

Main Methods:

• Systematic review of experimental and quasi-experimental studies.
• Searches conducted across major databases: Google Scholar, CINAHL, PubMed, Cochrane.
• Studies evaluated based on sample characteristics, study design, interventions, validity threats, and outcomes.

Main Results:

• Nineteen articles were reviewed, identifying clustered and individual developmental care strategies.
• Developmental care demonstrates potential positive effects on preterm infant neurodevelopment.
• Significant limitations were identified, impacting the validity of current research.

Conclusions:

• Developmental care shows promise but requires more consistent operationalization of components.
• Enhanced treatment fidelity and standardized data collection (including EEG and behavioral measures) are crucial for future studies.
• Further rigorous research is needed to solidify the evidence base for NICU interventions.
