BACKGROUND: Mycoplasma pneumoniae is a major pathogen causing community-acquired pneumonia/bronchitis in children, and macrolide-resistant strains are increasing in East Asian countries. Recent practice patterns, especially for antibiotic selection, and benefits of corticosteroid treatment in pediatric Mycoplasma pneumoniae infections remain unclear.
METHODS: Using the Japanese Diagnosis Procedure Combination inpatient database, we analyzed recent trends in antibiotic selection and corticosteroid use for pediatric Mycoplasma pneumoniae-related respiratory infections, using multivariable mixed effects logistic regressions. In addition, we compared hospital utilization and readmission between children who received corticosteroids and those who did not, using propensity-score matching and instrumental variable analyses.
RESULTS: Overall, 51,633 inpatients were identified. From 2010 to 2014, the use of macrolides and lincosamides decreased from 62.8% to 50.6% and from 25.6% to 13.7% respectively (Ptrend < 0.001), whereas fluoroquinolone use increased from 4.6% to 22.6% (Ptrend < 0.001). Tetracycline use did not demonstrate a significant change in trend. Propensity score matching analysis showed that hospital stay in the steroid group was 0.90 days longer than in the non-steroid group (95% confidence interval, 0.84-0.96). Total hospitalization cost was higher in the steroid compared to the non-steroid group (57.6 US dollars; 95% CI, 48.8-66.8). A significant difference in 30-day readmission risk was observed between the steroid (1.6%) and non-steroid (1.2%) groups (risk difference 0.4%; 95% CI, 0.1-0.7%). Similar results were observed on instrumental variable analyses.
CONCLUSIONS: Increasing trends in fluoroquinolone use and decreasing trends in macrolide use were observed. Our study did not prove the benefits of corticosteroid use. Further studies are required to confirm the clinical benefits of corticosteroid treatment.
