The Universe of Developmental Care Model (UDC) is a more recent reformulation of neonatal developmental care theory. This model was introduced in 2008 by Gibbins et al and portrays a patient- and family-centric environment within the health care universe. It expands on the Synactive Theory with the concept of a shared surface interface, portrayed as the skin forming a link between the body/organism and environment in which care is rendered and received. The UDC approach recognizes the interactive link between all developing systems and the caregiver/family while simultaneously providing a practical basis for formulating individualized patient care plans within the NICU's complex technological environment with emphasis on assessment and documentation.
