International survey of paediatric infectious diseases consultants on the management of community-acquired pneumonia complicated by pleural empyema

摘要

Aim Community-acquired pneumonia (CAP) complicated by pleural empyema is an important paediatric problem. Antibiotic management decisions are made on the basis of little available data and without strong specific recommendations in guidelines. Methods This was an online survey of paediatric infectious diseases (PID) physicians disseminated by major international professional organisations, examining empiric and targeted antibiotic choice, switch to oral antibiotics and duration of treatment for two hypothetical cases of contrasting severity. Results This study included 183 responses, mostly from North America, Western Europe and Australia/New Zealand. Increased disease severity was significantly associated with broader-spectrum and combination empiric and targeted antibiotic treatment, empiric methicillin-resistant Staphylococcus aureus (MRSA) coverage and both longer intravenous (IV) and total duration of antibiotic treatment. Empirical MRSA coverage was also associated with local prevalence. Clinical progress was most important for determining the timing of the switch from IV to oral antibiotics. Few respondents chose antibiotics with activity against organisms associated with atypical pneumonia (e.g. Mycoplasma, Chlamydia), and most did not choose agents that inhibit protein synthesis (e.g. clindamycin), even in the case of a severe invasive group A streptococcal infection. Some variation in targeted treatment choices reflected areas of uncertainty, such as Streptococcus pneumoniae susceptibility breakpoints, comparative effectiveness of anti-staphylococcal penicillins and first-generation cephalosporins for serious S. aureus infections and linezolid and vancomycin for MRSA pneumonia. Conclusions This international survey of PID physicians highlights the priority targets for clinical research to improve antibiotic treatment of CAP complicated by empyema. Interventions that might be studied include empirical antibiotic guidelines stratified by case severity, adjunctive empirical use of agents that inhibit protein synthesis (e.g. clindamycin) and approaches to encourage rapid IV-to-oral switch and shorter total antibiotic treatment.
