The Second Generation of the Laboratory Information System and the Laboratory Automation System in Osaka City University Hospital

The first total clinical laboratory system (TCLA) in the Osaka City University Hospital was introduced in 1993. After six years of operation, it was recently replaced by a new system. The goals of this replacement were as follows: 1. Improve the analytical performance. 2. Make the system operate more efficiently. 3. Improve the quality of laboratory analyses. We successfully reduced the labor required to operate the laboratory; made the laboratory reports quicker; reduced the number of retraction and revalidation of the results; and minimized the system downtime.
