Abstract: Objective: To investigate the current situation of patient delay and analyze the influencing factors in children with congenital heart disease in the Northern Guizhou region, in order to provide a basis for promoting early detection, diagnosis, and treatment of congenital heart disease in children in this region and improving their postoperative survival quality. Methods: A convenience sampling method was used to select 259 children with congenital heart disease and their main caregivers from two Class A tertiary comprehensive hospitals in the Northern Guizhou region as study subjects to investigate the current situation of patient delay andanalyze the influencing factors. Results: Among the 259 children, 219 cases(84.56%) experienced patient delay, with the longest delay being 168 months and the shortest 1 month. Logistic regression analysis revealed that the family′s place of residence, monthly household income, and the number of children were influencing factors for patient delay in children with congenital heart disease (P<0.05). Conclusion: The incidence of patient delay is high among children with congenital heart disease in the Northern Guizhou region, with a widespread phenomenon of patient delay. Children from rural areas, with lower economic income, and from larger families are more likely to experience patient delay.
