NCT01278485

Brief Summary

This is a multicenter, observational, retrospective and cross-sectional study to be conducted in a cohort of consecutively selected participants with type 2 diabetes mellitus (T2DM) who have been treated with sulphonylurea (SU) monotherapy or SU + metformin (MF) combination therapy by their cardiologist, nephrologist, or family practice doctor for at least 6 months prior to study enrollment. The purpose of the study is to assess treatment patterns, goal attainment rates, long-term diabetes complication rates, and frequency and severity of hypoglycemic episodes among T2DM participants treated in cardiology, nephrology and family practice settings.

Outcome Measures

Primary Outcomes (3)

  • Number of Participants Experiencing Hypoglycemic Episodes in the 6 Months Prior to Enrollment

    The participant experience of low blood sugar (hypoglycemia) questionnaire was used to evaluate participants' experience of hypoglycemia during the previous 6 months. Participants were asked to record whether they experienced hypoglycemia symptoms (yes/no) and to record the severity of those symptoms as mild, moderate, severe, or very severe.

    Up to 6 Months Prior to Enrollment

  • Number of Participants Experiencing Mild, Moderate, Severe, or Very Severe Hypoglycemic Episodes in the 6 Months Prior to Enrollment

    At the time of enrollment, participants were asked to rate their hypoglycemic episodes in the last 6 months as mild, moderate, severe, or very severe. Participants were able to select more than one category.

    Up to 6 Months Prior to Enrollment

  • Number of Participants With Hemoglobin A1c <7.0% at the Time of Enrollment

    Participant serum samples were collected after an overnight fast to determine the hemoglobin A1c level. Hemoglobin A1c is a measure of the percentage of glycated hemoglobin in the blood and provides an indication of participant blood glucose control in the 2 to 3 months prior to the evaluation.

Study Population

Adults with Type 2 diabetes mellitus ≥30 years of age who have been treated with sulphonylurea (SU) monotherapy or SU+ merformin (MF) combination therapy for at least 6 months by a cardiologist, nephrologist, or family practice doctor.

You may qualify if:

  • Participants diagnosed with type 2 diabetes mellitus (DM).
  • Participants at least 30 years of age at time of type 2 DM diagnosis.
  • Participants treated with SU monotherapy or SU + MF combination therapy for at least 6 months prior to enrollment.
  • Participants receiving diabetes care from a cardiologist, nephrologist or family practitioner for at least 6 months.
  • Participants with a clinical record in the health care center.
  • Participants in whose medical records a minimum core data set can be found; core data defined as: age, gender, duration of diabetes/age at diagnosis, all glucose-lowering medications (branded and generic names, dosage, dosing frequency, starting and stopping dates) since the start of all antihyperglycemic medications.

You may not qualify if:

  • Participants with Type 1 DM.
  • Participants who are pregnant or with gestational DM.
  • Participants receiving any anti-diabetic treatment from an endocrinologist/diabetologist in the previous 6 months.
  • Participants requiring daily concomitant usage of insulin.
  • Participants receiving any other oral diabetes medications other than SU or SU + MF.
  • Participants who are already participating in a clinical trial or other clinical study.
  • Participants for whom it would be impossible to complete the questionnaire.
