Abstract
- <bold>Background: </bold>Physicians "purchase" many health care services on behalf of patients yet remain largely unaware of the costs of these services. Electronic health record (EHR) cost displays may facilitate cost-conscious ordering of health services.<bold>Objective: </bold>To determine whether displaying hospital lab and imaging order costs is associated with changes in the number and costs of orders placed.<bold>Design: </bold>Quasi-experimental study.<bold>Participants: </bold>All patients with inpatient or observation encounters across a multi-site health system from April 2013 to October 2015.<bold>Intervention: </bold>Display of order costs, based on Medicare fee schedules, in the EHR for 1032 lab tests and 1329 imaging tests.<bold>Main Measures: </bold>Outcomes for both lab and imaging orders were (1) whether an order was placed during a hospital encounter, (2) whether an order was placed on a given patient-day, (3) number of orders placed per patient-day, and (4) cost of orders placed per patient-day.<bold>Key Results: </bold>During the lab and imaging study periods, there were 248,214 and 258,267 encounters, respectively. Cost display implementation was associated with a decreased odds of any lab or imaging being ordered during the encounter (lab adjusted odds ratio [AOR] = 0.97, p = .01; imaging AOR = 0.97, p < .001), a decreased odds of any lab or imaging being ordered on a given patient-day (lab AOR = 0.95, p < .001; imaging AOR = 0.97, p < .001), a decreased number of lab or imaging orders on patient-days with orders (lab adjusted count ratio = 0.93, p < .001; imaging adjusted count ratio = 0.98, p < .001), and a decreased cost of lab orders and increased cost of imaging orders on patient-days with orders (lab adjusted cost ratio = 0.93, p < .001; imaging adjusted cost ratio = 1.02, p = .003). Overall, the intervention was associated with an 8.5 and 1.7% reduction in lab and imaging costs per patient-day, respectively.<bold>Conclusions: </bold>Displaying costs within EHR ordering screens was associated with decreases in the number and costs of lab and imaging orders.
