Considering the importance of the role of health professionals in the neonatal comprehensive care, and also the low mean score of staffing-oriented care (43.51 out of 100) and also its items in NICUs in this study, it is concluded that more attention is needed for staff-oriented care as well as the strengthening of this dimension of developmental care along with other dimensions, through designing of appropriate interventions to improve the health outcomes of preterm infants.
