Facilitators of interdepartmental quality improvement: a mixed-methods analysis of a collaborative to improve pediatric community-acquired pneumonia management.

Background: Emergency medicine and paediatric hospital medicine physicians each provide a portion of the initial clinical care for the majority of hospitalised children in the USA. While these disciplines share goals to increase quality of care, there are scant data describing their collaboration. Our national, multihospital learning collaborative, which aimed to increase narrow-spectrum antibiotic prescribing for paediatric community-acquired pneumonia, provided an opportunity to examine factors influencing the success of quality improvement efforts across these two clinical departments.
