In the study, 85 adult patients with T2DM who were referred to the Diabetes Intense Medical Management (DIMM) clinic by their PCPs saw their mean hemoglobin A1C (HbA1C) levels fall by 2.4%, which subsequently resulted in an estimated medical costs savings of $9104 over 3 years for each patient, largely based on improved glycemic control. By comparison, 51 adult patients with T2DM who were treated by PCPs but did not participate in the pharmacist-led DIMM clinic experienced a mere 0.2% drop in mean HbA1C levels, which only translated to a $1803 reduction in 3-year medical costs per patient.
