title: Glucose meter accuracy and the impact on the care of diabetes in childhood and adolescence.
abstract: Blood glucose testing by point-of-care (POC) meters has become increasingly prevalent, and is an essential tool in diabetes management. But most of those who use the meters or rely upon their results for clinical decision-making are unaware of the significant limitations of these meters at present in both inpatient and outpatient settings. This review discusses the limitations of both strips and meters, in both hospital and outpatient settings, and the special problems when caring for diabetes in children and adolescents. It presents data that support the general concern among the experts that POC glucose meters are often inappropriate in critical care, as well reviewing when these meters are appropriate for use in other settings. The review discusses the problem of "outliers", glucose levels that deviate from the true glucose by a relatively large increment, and how these degrade clinical decision-making. Lastly, evidence-based recommendations are provided for changes that are needed to improve the present situation.
