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.

This study is a clinical trial to determine the impact on inpatient laboratory test ordering of presenting providers with medicare fee data at the time of order entry. We will randomly assign 60 laboratory tests to an active arm (medicare fee data displayed) or to a control arm (medicare fee data not displayed). 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).
