BACKGROUND: Real-time continuous glucose monitoring systems (RT-CGMS) are a recently introduced technology for type 1 diabetes and experience in children is limited. OBJECTIVE: To assess patient and caregiver's perception of benefits and disadvantages of RT-CGMS in children or young adults with type 1 diabetes mellitus (DM) on insulin pump therapy. SUBJECTS AND METHODS: Forty-three subjects (3-25 yr) on insulin pump therapy were included in the study. Thirty-four used RT-CGMS for a short-term trial (4 wk, ST group) and nine as a long-term tool (2-18 months, LT group). Forty subjects or their caregivers completed a questionnaire. RESULTS: On the basis of the questionnaire responses, hypoglycemia prevention was the most common perceived benefit (88%), followed by elimination of hypoglycemia-related anxiety (83%), ease of pattern management (85%), improvement of diabetes control (80%), improvement of quality of life (78%), and ease of diabetes care (78%). Negative effects included irritation/annoyance from the sensor alarm (48%) and insertion site bruising, pain, or irritation (43%). A small percentage of patients who were interested in purchasing the device (12%) decided against using it LT after a 4-wk trial on RT-CGMS. CONCLUSIONS: The most common perceived benefits of RT-CGMS are prevention of hypoglycemia and decrease in hypoglycemia-related anxiety. Negative effects are uncommon and seem to be unlikely to affect the decision to use RT-CGMS for a LT. A ST trial seems to be a valuable tool for the patient/caregiver in determining whether to purchase the device and in setting realistic expectations of its potential benefits.
