Abstract: Objective: To apply the evidence of promoting direct breastfeeding in infants with Congenital Heart Disease (CHD) after surgery to clinical practice and evaluate its effectiveness, and to provide ideas for nursing staff to carry out evidence-based practice, evidence application, and clinical transformation. Methods: Following the "evidence clinical transformation model" of the Evidence based Nursing Center of Fudan University, we summarized the evidence on promoting direct breastfeeding of infants with CHD after surgery, formulated the corresponding clinical review indicators, reviewed and analyzed the obstacles one by one, constructed the implementation strategy and carried out practical reform. Results: Compared with the baseline review, nurses' awareness of the implementation rate and evidence related knowledge of the review indicators, maintenance rate of direct breastfeeding, maintenance rate of exclusive breastfeeding and breastfeeding (including exclusive breastfeeding and mixed feeding), and maternal breastfeeding confidence score were significantly improved (P<0.01). Conclusion: The application of evidence to promote direct breastfeeding in infants with CHD after surgery has clinical significance in regulating the behavior of nurses, improving their mastery of evidence-based knowledge, improving the maintenance rate of direct breastfeeding in infants with CHD after surgery, the maintenance rate of pure breastfeeding and breastfeeding, and maternal breastfeeding confidence.
