![]() ![]() Most BGMs are generally overestimating true glucose concentration at high altitude. Two GDH based BGMs did not meet set performance criteria. No significant difference was observed between measurements at simulated altitude and sea level for either glucose oxidase based BGMs or glucose dehydrogenase based BGMs as a group phenomenon. ![]() The corresponding probabilities for autocoded and correctly coded manual meters were 2.52% (p 6.5 mmol/L) and <1 mmol/L from reference glucose (when <6.5 mmol/L). For miscoded meters, the estimated probability to produce a blood glucose reduction to less than or equal to 70 mg/dl was 10.40%. Conversely, an error less than or equal to -70 mg/dl would be required to derive an insulin dose insufficient to correct an elevated blood glucose to less than 180 mg/dl. Results Using insulin sensitivity data, it was determined that, given an actual blood glucose of 150–400 mg/dl, an error greater than +40 mg/dl would be required to calculate an insulin dose sufficient to produce a blood glucose of less than 70 mg/dl. Deviations of meter blood glucose results from the reference method (YSI) were used to predict insulin dose errors and resultant blood glucose outcomes based on these deviations. Subjects (n = 116) had finger stick blood glucose obtained at fasting, as well as at 1 and 2 hours after a fixed meal (Boost® Novartis Medical Nutrition U.S., Basel, Switzerland). Two of each set of manually coded meters were deliberately miscoded, and one from each set was properly coded. Two sets of meters were autocoded and therefore could not be miscoded, and three sets required manual coding. Methods Five sets of glucose meters were used. It attempts to relate potential insulin dose errors to possible adverse blood glucose outcomes when glucose meters are miscoded. ![]() This paper reflects additional analyses performed with data from Raine et al. Studies have demonstrated the occurrence and impact on insulin dose of coding errors with SMBG meters. Objectives The proper use of many types of self-monitored blood glucose (SMBG) meters requires calibration to match strip code.
