Abstract
The objective of this study is to determine predictors of resource use among pediatric providers for common respiratory illnesses. We surveyed pediatric primary care, emergency department (ED)/urgent care (UC), and hospital medicine providers at a free-standing children's hospital system. Five clinical vignettes assessed factors affecting resource use for upper respiratory infections, bronchiolitis, and pneumonia, including provider-type, practice location, tolerance to uncertainty, and medical decision-making behaviors. The response rate was 75.3% (168/223). The ED/UC and primary care providers had higher vignette scores, indicating higher resource use, compared with inpatient providers; advanced practice providers (APPs) had higher vignette scores compared with physicians. In multivariate analysis, being an ED/UC provider, an APP, and greater concern for bad outcomes were associated with higher vignette scores. Overall, provider type and location of practice may predict resource use for children with respiratory illnesses. Interventions targeted at test-maximizing providers may improve quality of care and reduce resource burden.
