Secular Trends in the Clinical Characteristics of Type 2 Diabetic Patients With Severe Hypoglycemia Between 2008 and 2013

Abstract

Background: We investigated the trends in the clinical characteristics and prescriptions of type 2 diabetic patients with severe hypoglycemia because the prescription rate of antidiabetic agents has significantly changed recently.

Methods: A total of 193 patients with type 2 diabetes with severe hypoglycemia induced by antidiabetic agents between 2008 and 2013 were divided into three groups based on the period of visit: 2008 - 2009, 2010 - 2011 and 2012 - 2013.

Results: While the proportion of patients with severe hypoglycemia using insulin (from 55% to 74%), biguanides (from 6% to 20%), glinides, and dipeptidyl peptidase-4 inhibitors significantly increased, those using sulfonylureas (from 45% to 20%) significantly decreased. Errors of drug use significantly increased as a trigger of hypoglycemia in recent years. The number of antidiabetic agents (from 1.9 0.6 to 2.3 0.7), non-diabetic agents (from 2.3 2.4 to 4.3 3.3), and total drugs prescribed were significantly higher in recent years among patients receiving insulin therapy.

Conclusions: Polypharmacy especially in patients receiving insulin therapy and errors of drug use have increased in type 2 diabetic patients with severe hypoglycemia in recent years. Intensive education in the usage rule of drugs is considered to be important in order to prevent severe hypoglycemia.
