Objective To explore the discharge preparation and home care information needs of premature infants with bronchopulmonary dysplasia(BPD)in the neonatal intensive care unit(NICU)from the perspective of their parents,in order to provide a basis for adopting scientific and effective discharge preparation intervention plans.Method A total of 12 parents of premature infants with BPD in the NICU of Guizhou Medical University Affiliated Hospital from December 2021 to August 2022 were selected as the research subjects by using purposive sampling method.Qualitative research was used to conduct semi-structured in-depth interviews with the parents of premature infants with BPD,and Colaizzi phenomenological analysis was used to organize and analyze the data.Results There were extracted 4 themes,namely diverse knowledge needs,insufficient role adaptation,uncertainty in discharge preparation,and emotional changes.Conclusion Parents of children with BPD indicate the need for adequate prepara-tion and personalized guidance to reduce anxiety and uncertainty during the transition to discharge.Therefore,it is necessary to improve care skills and disease-related knowledge,which can help parents adapt to their roles,and the support and guidance of multidisciplinary teams may be crucial for the discharge preparation process,especially for the follow-up services of premature infants with BPD,providing reference for the continuity of care services for fami-lies with BPD after discharge.
