AbstractPoint-of-care testing (POCT) for the management of patients with diabetes has become a standard of care. Originally, diabetic monitoring was accomplished by manual urine dipsticks. The development of hand-held, battery-operated capillary glucose monitors radically improved the ability of physicians and nurses to monitor diabetic patients during their hospital stay. Capillary glucose meters have been shown to provide accurate results under controlled conditions, but a number of early meters had issues with the quality of testing when used by non-laboratory personnel. Bedside capillary glucose testing was first initiated in our hospital in 1990, using a first-generation glucose meter that could measure a glucose value within 2 min. Operator errors were common because the glucose strips required wiping and the testing required timing. Furthermore, these early meters had no data storage or data management capabilities. In 1995, we transitioned to a second-generation meter with a rudimentary data management and storage capability that could be downloaded to a portable laptop. A log of quality control (QC) data could be derived from the download. A major problem with this device was the need to bring the instruments and laptop together, which was labor intensive and difficult to sustain over long periods of time in a large institution. We recently implemented a third-generation instrument (the Abbott Precision PCx) with a data management system (Precision NET). This device significantly expands the data management and networking capabilities of the bedside glucose meter, as shown in Table 5. Glucose values can now be performed in a fraction of the time of the first-generation meters, the need to wipe the glucose strips has been eliminated, and only certified operators can use the instrument. Networking technology allows for centralized quality control management, and the ability to network with other point-of-care technologies using intranet and in the near future internet applications. Collectively, these developments have radically improved the efficiency and quality of bedside capillary glucose testing, and have significantly enhanced the ability to manage this important technology.
