Basal-bolus insulin therapy, which includes one injection of long acting insulin and three
injections of short acting insulin is the most commonly used insulin treatment. However, many
older patients find the basal-bolus insulin regimen hard to manage because it involves 4
injections and 4 blood glucose tests each day. It is possible that a simplified treatment
that involves one injection of long acting insulin daily and two blood glucose tests daily
might be equally effective. This simplified regimen, if effective, would be easier to use and
might result in less errors. Therefore, the investigators want to conduct this study to
compare using a single daily injection of basal insulin with the usual basal-bolus insulin
regimen in elderly patients (age >65 years) with type 2 diabetes.
