Clinical score for early escalation in pediatric A2063G Mycoplasma pneumoniae pneumonia: a retrospective cohort study

A simple clinical scoring model incorporating PCT, TSS, co-pathogen burden, bronchoscopy status, and age demonstrated good predictive accuracy in identifying children with A2063G-positive MRMP pneumonia who may benefit from early escalation to second-line therapy. Its use in clinical practice may support timely intervention for high-risk patients while minimizing unnecessary antibiotic escalation. Further prospective validation in multicenter cohorts is needed to confirm its generalizability and clinical utility.
