The developing status of pediatric day-care surgery is comprehensively analyzed based on SWOT model from the following four dimensions: strength (S), weakness (W), opportunities (O) and threats (T). Day-care surgery strategy is in line with the characteristics of pediatric diseases, which can improve medical efficiency and reduce medical costs. However, it is limited by both the particularity of pediatric patients and the complexity of postoperative management. In terms of external environment at present, there are many opportunities for its development of day-care surgery such as national policy support, medical technology innovation, and regional medical center construction. Nevertheless, some threats cannot yet be ignored such as medical safety risks, unfair resource allocation, traditional habit of medical treatment and medical insurance payment policies. In order to promote the high-quality development of pediatric day-care surgery in the future, it is recommended to innovate medical service models, improve medical quality management systems, train medical qualified personnel, and enhance national policy support.
