A clinician's workstation for improving laboratory use. Integrated display of laboratory results

Physicians are often forced to make decisions about the use of laboratory resources without adequate access to earlier results and related supporting information. Less than optimal use of the laboratory may result. The authors developed and deployed a clinical workstation meant to provide ready access to laboratory information that is presented in a format well-matched to the patient monitoring task. The workstation was one element of a multifaceted effort to improve blood component use in adult and pediatric bone marrow transplantation units. It was the sole intervention focused on improving laboratory testing. In the 2 years since the introduction of the workstation, median charges of bone marrow transplantation cases for laboratory test fell by 32%. This reduction in charges has been maintained for 2 years. Better informed physicians appear to use laboratory resources more sparingly.
