Abstract: Objective To explore the effect of family-integrated care on the growth and development of premature infants in neonatal transition ward, provide clininal reference for standardizing family-integrated care, improve the quality of care of premature infants after discharge, promote their growth and development, and reduce their readmission rate. Methods From January to October 2022, 42 premature infants and their mothers who were born and admitted to the neonatal transition unit at the General Hospital of Ningxia Medical University were selected as study subjects, and were divided into a control group （20 cases）and an intervention group （22 cases） according to random number table method. The control group was treated with traditional nursing methods, and the intervention group was treated with family-integrated care on the basis of the control group. During the hospital stay, the physical indexes of the two groups of preterm infants were observed and recorded every day, the neonatal growth and development indexes of the two groups before discharge were recorded, and two independent samples were analyzed by t-test. Results The general data of preterm infants in the two groups were balanced at baseline, the weight and body length of preterm infants in the intervention group were higher than those in the control group after the implementation of family-integrated care （P<0.05）, and the head circumference of the intervention group was higher than that of the control group, but the difference was not statistically significant （P>0.05）. Conclusion The educational content of neonatal care should be homogeneous. Standardized family-integrated care promotes the growth and development of premature infants, which is worthy of clinical application.
