Point of care testing informatics: The critical care-hospital interface

Point of care testing (POCT), a new paradigm in laboratory testing, has recently been introduced to the critical care setting. In this model, laboratory testing is performed in the critical care vicinity by local bedside personnel. POCT devices perform user selected critical care tests on whole blood in a timely and accurate fashion. The POCT data, while used immediately at the bedside, must still be managed in accordance with regulatory guidelines and incorporated into the laboratory or hospital information system. Currently, critical care physicians are not educated and trained in the intricacies of laboratory data management and device interfacing. This article addresses the technical, political, and implementation issues surrounding POCT data management and interfacing as well as the philosophical and practical differences in laboratory data management between the central laboratory and POCT sites.
