Popis: 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. To determine whether displaying hospital lab and imaging order costs is associated with changes in the number and costs of orders placed. Quasi-experimental study. All patients with inpatient or observation encounters across a multi-site health system from April 2013 to October 2015. Display of order costs, based on Medicare fee schedules, in the EHR for 1032 lab tests and 1329 imaging tests. 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. 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
