Abstract

Introduction: Self-Monitoring blood glucose (SMBG) has a critical role in the management of patients treated with insulin. Technical and environmental factors significantly affect the accuracy of glucometers. The objective is to establish the clinical and numerical precision of the glucometers used in Colombia, compared to central blood glucose.

Methods: Study of diagnostic tests, glucometers of the basic health plan (GluNeo, GlucoQuick, Optium Neo, Select Plus and Gluco Quick Diamond Voice) were evaluated. Adults treated with an insulin infusion pump integrated with a continuous monitoring system were included. The samples were classified as:>100mg dL,>70 and 100 mg/dL, ?70 mg/dL. For glucose ?100 mg/dL a bolus of insulin was delivered using the bolus wizard feature. The numerical precision was evaluated using the mean absolute relative difference (MARD) and the clinical precision according to the proportion measurements in the zones A + B of Clarke and Parkes (Consensus) error grids.

 Results. 830 measurements were analyzed. All devices met precision requirements for glucose >100mg / dL. Optium Neo and Gluco Quick Diamond Voice, achieved compliance standards by combining all measurement levels of 12.1% and 13.9%, respectively. The clinical precision for these two devices was 98% and >95% according to the Parkes (Consensus) and Clarke error grids, respectively. Greater variability of the results was evidenced in the range ?70mg/dL.

Conclusions. The numerical precision was adequate for the devices evaluated for capillary glucose values >100mg/dL and decreases with values ??<100mg/dL. Gluco Quick Diamond Voice and Optium Neo had adequate global numerical and clinical precision.
