REX: Extralaboratory cycle of information processing from laboratories to care units

REX, developed in the Rouen University hospital, allows the complete computerization of extralaboratory cycle of lab test numerical results from laboratories to care units. This cycle includes a real time transmission on terminals as soon as the test is realized and a batch print every evening. In laboratories, most of the lab tests results are directly acquired from automated devices. This application is integrated into our hospital information system. It is operational since the second semester of 1989. Every day, 18 000 lab tests results are transmitted by REX and 10 000 transactions by health professionals are done. Beyond amelioration of speed and reliability of the extralaboratory cycle of lab test results, REX decreases work time linked to phone transmission in laboratories and care units.
