| Sumario: | Background: Variability in developmental care implementation in the neonatal intensive care unit (NICU) highlights the need to explore barriers to care delivery, yet few studies addressed these challenges. Purpose: Drawing from NICU literature, this integrative review identifies barriers to implementing developmental care with premature infants. Methods: A systematic search of CINAHL and PubMed (2014-2024) was conducted, yielding 2 qualitative and 5 quantitative studies. Results: Thematic analysis revealed 3 key barriers based on the theory of planned behavior: attitude, subjective norm, and perceived control. Conclusions: To improve developmental care, a multi-pronged approach engaging stakeholders is recommended. Future research should apply rigorous implementation science methods to overcome these barriers.
