Abstract
Introduction: Differences in the comparability of the INR of patients on oral anticoagulation (OAC) therapy cause often unsteadiness in patients and treating doctors.
Methods: Because of that but also with respect to structural and quality control reasons we went off from the system of using a second thromboplastin for OAC-patients and PT-values below 50% and implemented a new bidirectional interlaced Point-Of-Care-Testing (POCT)-system for the measurement of INR in capillary whole blood from the finger tip for orally anticoagulated out-patients, which is compatible with the recombinant thromboplastin (Innovin, Dade Behring) used in the routine- and emergency laboratory of our hospital. Our new system has a capacity of 50–60 patients/hour and is based upon three POCT machines (INRatio, HemoSense Inc.,USA) switched into series and connected bi-directional via a PC with a newly developed software to the Laboratory Information-System (LIS) (GLIMS/MIPS, Belgium) with a positive (via barcode scanner) patient identification. INR is determined with reagent strips (HemoSense, INRatio-INR Test Strip) and capillary whole blood. A high and a low INR value in each strip serves as internal quality control.
Results: An external quality assessment scheme (ÖQUASTA) for POCT-INR is also available in Austria. A medical online-anti-coagulation scheme based upon the determined INR value and the linked patient data has been developed within the LIS. INR values are documented in the LIS but are also transferred to the KIS (Hospital Information System). The INR values and the recommended weekly dose of medication are documented cumulatively in a virtual patient datasheet in LIS and guarantees a paper-free ambulance routine. The maintenance costs have been linked to the break-even-point: the saving of the second thromboplastin compensated the higher price for the INR strips.
Conclusions: To our knowledge this system is unique so far and has proved to be efficient in our daily hospital routine.
