In order to explore the clinical efficacy of knowledge, information, and action theory combined with clinical nursing in children with asthmatic bronchitis (AB) and to analyze the influencing factors of poor prognosis, a total of 98 children with AB in our hospital from January 2021 to August 2022 are collected. The baseline data are analyzed and are randomly divided into a combination group (n = 49) and a single group (n = 49). The experimental results show that the baseline data of the research subjects are not comparable (P > 0.05), the clinical efficacy of the combined group is higher than that of the single group, and the level of pulmonary function indexes in the combined group is significantly higher than that of the single group (P < 0.05). The observation shows that family history, repeated respiratory virus infection, and allergy history are all risk factors affecting the prognosis of children with AB.
