A nomogram prediction model for plastic bronchitis in children with refractory Mycoplasma pneumoniae pneumonia

Objective: Pneumonia (RMPP) and facilitate early intervention. Methods: A retrospective study of 205 hospitalized children diagnosed with RMPP in two tertiary hospitals was conducted from January 2023 to May 2025. The children were divided into the PB group and non-PB group. Clinical characteristics, laboratory indices, pulmonary imaging findings, and treatment approaches were compared between the two groups. A nomogram model was established based on logistic regression to assess the risk of PB in children infected with RMPP. Results: = 8.269)]. Decision curve analysis showed that the model had clinical value. Conclusions: Early identification of these risk factors (CRP > 20 mg/L, pleural effusion, and elevated LDH) may facilitate timely bronchoscopic examination in children with RMPP at high risk of PB, potentially contributing to improved clinical management.
