“…These alarms may go off in the middle of the night for low or high blood sugars and may not correlate with blood glucose meter readings or be set at appropriate thresholds [42]. Because there can be a very large error rate for modern CGM systems at extreme but clinically relevant glucose concentrations, particularly for glucose values < 70 mg/dL when the glucose is changing rapidly [9], patients and families must be made aware of the limitations of the device they are using.…”

“…A major barrier for patients is that frequent use is required, with studies showing that both adults and children only benefit significantly if CGM is used more than 70% of the time (≥ 5 days per week) [8]. In addition, there are important limitations to CGM (such as inconsistency in both accuracy and precision when measuring low blood sugars), and clinicians who do not routinely use CGM may feel ill-equipped to educate patients properly on these limitations [9]. Identifying which children with T1D should use CGM has proven difficult and requires teaching families that CGM requires intensive management and will not replace time-consuming SMBG.…”

Continuous glucose monitoring (CGM), while a relatively new technology, has the potential to transform care for children with type 1 diabetes. Some, but not all studies, have shown that CGM can significantly improve hemoglobin A1c levels and reduce time spent in the hypoglycemic range in children, particularly when used as part of sensor-augmented pump (SAP) therapy. Despite the publication of recent clinical practice guidelines suggesting CGM be offered to all children 8 years of age or older who are likely to benefit, and studies showing that younger children can also benefit, this technology is not yet commonly used by children with type 1 diabetes. Effects of CGM are enhanced when used on a near-daily basis (a use-dependent effect) and with insulin pump therapy. Therefore, coordinated strategies are needed to help children and their families initiate and continue to use this resource for diabetes care. This review introduces CGM to pediatric endocrinologists who are not yet familiar with the finer details of this technology, summarizes current data showing the benefits and limitations of CGM use in children, reviews specific case examples demonstrating when CGM can be helpful, and shows the value of both retrospective and real-time CGM. It is hoped that this information leads to discussion of this technology in pediatric endocrinology clinics as an important next step in improving the care of children with type 1 diabetes.

“…Our study showed glucose meters performed best at normal PG concentrations, and less well in the hypoglycemic range, consistent with the findings of several previous studies. [26][27][28] The conditions of our study were more challenging that point-of-care glucose meters are likely to encounter in typical outpatient settings because we included many hypoglycemic samples and samples with a wide range of hematocrit values. We evaluate whether the meter meters met the accuracy criteria stipulated by the ISO 15197:2003 and ISO 15197:2013 in the setting of our study.…”

Background: The accuracy of point-of-care blood glucose (BG) meters is important for the detection of dysglycemia, calculation of insulin doses, and the calibration of continuous glucose monitors. The objective of this study was to compare the accuracy of commercially available glucose meters in a challenging laboratory study using samples with a wide range of reference BG and hemoglobin values. Methods:Fresh, discarded blood samples from a hospital STAT laboratory were either used without modification, spiked with a glucose solution, or incubated at 37°C to produce 347 samples with an even distribution across reference BG levels from 20 to 440 mg/dl and hemoglobin values from 9 to 16 g/dl. We measured the BG of each sample with 17 different commercially available glucose meters and the reference method (YSI 2300) at the same time. We determined the mean absolute relative difference (MARD) for each glucose meter, overall and stratified by reference BG and by hemoglobin level. Results:The accuracy of different meters widely, exhibiting a range of MARDs from 5.6% to 20.8%. Accuracy was lower in the hypoglycemic range, but was not consistently lower in samples with anemic blood hemoglobin levels. Conclusions:The accuracy of commercially available glucose meters varies widely. Although the sample mix in this study was much more challenging than those that would be collected under most use conditions, some meters were robust to these challenges and exhibited high accuracy in this setting. These data on relative accuracy and robustness to challenging samples may be useful in informing the choice of a glucose meter.

“…Most patients had high capillary glucose levels, which were considered reliable as they were in agreement with glycosylated haemoglobin (34)(35)(36) . These results show that metabolic control was poor even though patients had access to specialist care.…”
