Background: Insulin pump (IP) is very popular and efficient mean for T1DM treatment in paediatric population. Delivery of basal insulin is automatically regulated 24 h basal set up. But, boluses must be delivered in meal time and their number and type are different.

Aims and objectives: To evaluate number and type of boluses in IP treatment of T1DM children and to correlate them with clinical features of the patients and metabolic control of their T1DM.

Methods: T1DM patients from Pediatric Clinic in Sarajevo with insulin pump treatment were participants in this study. We used two consecutive download data and data from corresponding two controls.

Results: We analyse data from 41 patients (24 males/17 females), mean age 13.5 years, 15 prepubertal/26 pubertal, mean diabetes duration 7.1±2.4 years, mean HbA1c 8.9±1.3%., delivered mean 5.4±1.65 boluses daily. Lowest HbA1c (7.6±1.0%) was in patients delivered 8–10 boluses daily, and the worst HbA1c (11.1±2.1%) was in patients with 1–3 boluses daily. NS difference was between bolus number (5.6/5.3) in prepubertal and pubertal patients. Only 12 patients (29%) used bolus wizard (BW) calculation in everyday pump use, and they had significantly lower HbA1c than non BW users (8.22/8.99%, P<0.05). Patients delivered more insulin of total daily insulin intake in bolus form had significantly lower HbA1c level (P<0.05). There was no significant difference in correlation of number of delivered boluses and diabetes duration, and with duration of insulin pump treatment.

Conclusions: Frequent downloading and analysing data from IP memory especially bolus delivery evaluation are very important for better regulation of T1DM in paediatric patients with IP treatment.
