About

This is a clinical trial to evaluate the impact of presenting medicare fee data for inpatient laboratory tests in the electronic health record on provider ordering behavior at a tertiary care hospital.

The primary outcome will be the change in the ratio of tests ordered per patient day over 12 months by study group (intervention vs. control).
