Dietitian-Nutritionist vs. Day Hospital in the Metabolic Control of Patients With Type 2 Diabetes

The present study aims to compare the effects on glycated hemoglobin (HbA1c) at 3 months of two care models in patients with type 2 diabetes referred due to poor glycemic control: a day hospital endocrinology care model versus a care model centered on follow-up by a dietitian-nutritionist.
