Homeostasis model assessment (HOMA) as surrogate insulinization criteria in patients with type 2 diabetes.

Type 2 diabetes mellitus is a metabolic disorder that results from defects in both insulin secretion and insulin action. Questions remain about when insulin therapy is indicated; thus, the aim of this study was to evaluate homeostasis model assessment beta-cell (HOMAbetacell) values as surrogate criteria for insulin therapy indication in patients with type 2 diabetes. A prospective study was performed involving 189 type 2 diabetic patients with deficient metabolic control assessed by clinical and laboratory parameters.
