Multicenter Study Comparative StudyInterinstitutional comparison of bedside blood glucose monitoring program characteristics, accuracy performance, and quality control documentation: a College of American Pathologists Q-Probes study of bedside blood glucose monitoring performed in 226 small hospitals.
To assess the accuracy of bedside blood glucose monitoring (BGM) in small hospitals, to assess the compliance with which hospital workers performing bedside BGM adhere to quality control (QC) procedures, and to identify those practice characteristics in small hospitals that are associated with better BGM accuracy and with better performance of BGM QC. ⋯ We found the rates of BGM accuracy and of QC performance adequacy achieved in small hospitals to be similar to those determined in previous Q-Probes studies conducted in large institutions. A significant amount of institutional bedside testing does not meet current standards for accuracy or for quality control. Some institutions may improve their accuracy and/or QC performances by having laboratory personnel intimately involved in their institution's BGM QC program, by routinely comparing BGM results with those performed using glucose analyzers in the clinical laboratory, by routinely running three rather than two glucose QC control levels, by participating in external proficiency programs, and by strictly adhering to institutional QC protocols.

Multicenter StudyMulticenter study of oxygen-insensitive handheld glucose point-of-care testing in critical care/hospital/ambulatory patients in the United States and Canada.
Existing handheld glucose meters are glucose oxidase (GO)-based. Oxygen side reactions can introduce oxygen dependency, increase potential error, and limit clinical use. Our primary objectives were to: a) introduce a new glucose dehydrogenase (GD)-based electrochemical biosensor for point-of-care testing; b) determine the oxygen-sensitivity of GO- and GD-based electrochemical biosensor test strips; and c) evaluate the clinical performance of the new GD-based glucose meter system in critical care/hospital/ambulatory patients. ⋯ The performance of GD-based, oxygen-insensitive, handheld glucose testing was technically suitable for arterial specimens in critical care patients, cord blood and heelstick specimens in neonates, and capillary and venous specimens in other patients. Multicenter findings benchmark the performance of bedside glucose testing devices. With the new +/-15 mg/dL --> 100 mg/dL --> +/-15% accuracy criterion, point-of-care systems for handheld glucose testing should score 95% (or better), as compared with the recommended reference method. Physiologic changes, preanalytical factors, confounding variables, and treatment goals must be taken into consideration when interpreting glucose results, especially in critically ill patients, for whom arterial blood glucose measurements will reflect systemic glucose levels.

Multicenter StudyBedside glucose monitoring quality control practices. A College of American Pathologists Q-Probes study of program quality control documentation, program characteristics, and accuracy performance in 544 institutions.
To investigate the adequacy of bedside glucose monitoring (BGM) quality control documentation and monitoring, characterize program structure and organization, and identify characteristics associated with the ability to produce accurate results. ⋯ There is a need for improving compliance with QC documentation, improving appropriate corrective action follow-through, decreasing the frequency of inappropriate patient testing, and improving BGM accuracy performance. We provide recommendations for improvement.

Multicenter Study Comparative Study Clinical TrialExacTech blood glucose meter clinical trial.
Current prehospital protocols for the management of patients with altered mental status include the empiric administration of hypertonic glucose, naloxone, and thiamine. The injudicious use of 50% dextrose (D50W) may result in hyperosmolarity, a worsening of hypokalemia, and unwarranted additional health-care costs for the patient. The administration of D50W also may worsen the neurological outcome of patients with local or generalized ischemia. ⋯ The device functioned accurately and consistently in the prehospital environment over a wide range of temperatures, and in the hands of many different individuals.
