According to the scientific literature, the insulin pump is effective and does not involve greater risks than the comparator therapy, multiple injections with Neutral Protamine Hagedorn (NPH), if precautions are taken. However, the efficacy gain is clearly more pronounced for patients - both adults and children - who meet specific clinical and psychosocial criteria. Study data indicate that the pump's efficacy is comparable to that of multiple injections with glargine for all adult diabetic patients. Since the pump is very expensive, and since insulin glargine should soon be available in Quebec, there is less interest in pump therapy for adult diabetics. Nonetheless, for some adult patients who may not be able to achieve adequate glycemic control via multiple injections with glargine, the pump could prove to be an efficient option. For children, insulin glargine seems to be less promising than for adults.
