Objective: To evaluate the reliability and accuracy of diary entries in relation to glucometer memory in children with T1D and its impact on mid-term glycemic outcomes.

Material and method: The SMBG (Self-monitoring blood glucose) in the diaries were compared to the readings from the memory of the glucometer conforming to the international standard ISO 15197 by the ''EMPECS'' software in 2 groups of 10 diabetics (G1 control, G2 familiar with the software) for a period of 6 weeks, aged between 6 and 16 years old; with a duration of T1D of 1 to 13 years, followed in diabetology consultation.

Results: 164 SMBG on average, i.e. 3.5/d, were reported in the diary vs. 3.9 taken/d for G1 and 177 SMBG, i.e. 3.65/d, vs. 4.2 taken/d for G2. Errors in the blood glucose graphs were observed in 1.3% of the values reported in (G1) vs. 0.3% (G2); fabrications in 1.7% (G1) vs. 2.4% (G2). On the other hand, 85% of catches were accurate in (G1) vs. 94% (G2). The omissions were more pronounced in G2. The 3 children with 100% accurate SMBG recordings had a mean reduction in HbA1c of -0.76 at the 3rd month of follow-up.

Conclusion: The reliability of SMBG diaries is a major problem in children with T1DM, and it would be worthwhile incorporating the reading software into the diabetology consultation and using continuous glucose monitoring systems (CGM) for better control.
