Background: There are few reports on rates and predictors for pump discontinuation in the pediatric population.
Objective: To study the rate of and predictors for insulin pump discontinuation among pediatric patients with type 1 diabetes.
Methods: Medical chart review of 530 patients with type 1 diabetes who had started pump therapy between 2000 and 2008 in our center revealed that 11.3% had discontinued pump use after 3 d to 5 yr; of these, 9.1% discontinued pump use at least 3 months after initiation. Relevant data were retrieved from the files of these patients and from those of 100 randomly assigned pump-treated patients.
Results: The pump discontinuation group had a significantly higher proportion of female patients (75 vs. 46%, p = 0.001) and patients above 10 yr of age (93.8 vs. 80%, p = 0.03) than the reference group. Comparable findings were noted for age at diagnosis, pubertal stage, anthropometric data and duration of diabetes at pump initiation, rate of severe hypoglycemic and diabetic ketoacidosis episodes. There were no between-group differences in number of daily insulin injections and blood glucose measurements before pump treatment. At pump initiation, HbA(1c) was significantly higher in patients discontinuing pump therapy than in the controls (8.6 ± 1.4 vs. 8.1 ± 1.0, p = 0.02). This difference was maintained at the last follow-up visit recorded.
Conclusions: Almost 90% of our cohort maintained pump therapy. Female gender, age older than 10 years in girls and poor metabolic control at pump initiation were associated with higher risk for pump discontinuation - for such patients intensified individual and family support may serve to maximize persistent pump therapy.
