About this study

Official title: Naturalistic Evaluation of Hypoglycemic Events in Diabetic Subjects

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Up to 6 Months Prior to Enrollment

  2. 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.

    Measured: Up to 6 Months Prior to Enrollment

  3. 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.

    Measured: Day of Enrollment

Secondary outcomes (7)
  1. Participant Mean Score on the EuroQol-5 Dimension (EQ-5D) Quality-of-Life Questionnaire At the Time of Enrollment

    The EQ-5D is a questionnaire that assesses participant quality of life in 5 domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each domain has 3 levels: no problems, some problems, extreme problems for which participants are asked to self-rate their experience. The EQ-5D total score ranges from -0.171 (worst health state) to 1 (perfect health state) and 1 reflects the best outcome.

    Measured: Day of Enrollment

  2. Participant Mean Score on the EuroQol Visual Analog Scale (EQ-VAS) Quality-of-Life Questionnaire At the Time of Enrollment

    Participant health status was self-reported in 5 domains (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and was analyzed by using visual analog scale (VAS) which records participant responses on a scale of 0 (poor health) to 100 (excellent health).

    Measured: Day of Enrollment

  3. Participant Mean Score on the Treatment Satisfaction Questionnaire for Medication (TSQM) At the Time of Enrollment

    The TSQM is a treatment satisfaction questionnaire containing 14 items covering the following dimensions: side effects, effectiveness, convenience, and global satisfaction. Participants were asked to respond in a yes or no fashion, or by using a 5- or 7-point Likert scale. The score for each dimension ranges from 0 to 100, with a higher score expressing a better quality of life.

    Measured: Day of Enrollment

  4. Participant Mean Score on the Self-Reported Adherence and Barriers Questionnaire At the Time of Enrollment

    The self-reported adherence and barriers questionnaire to measure treatment compliance asked participants to rate their responses to 5 questions: How often do you take your diabetes medicines exactly as your healthcare provider prescribes them?; During the past 4 weeks, how often were you unsure about some of the things your doctor suggested you do for your diabetes?; During the past 4 weeks, how often were you unable to do what was necessary to follow your doctor's treatment plans for your diabetes?; During the past 4 weeks, how often were you bothered by side effects from your medicines?; and During the past 4 weeks, how often did you have problems getting your prescriptions filled? Participants responded using a scale of 1 to 5, where 1=always, 2=usually, 3=sometimes, 4=rarely, and 5=never.

    Measured: Day of Enrollment

  5. Participant Mean Score on the Worry Scale of Hypoglycemia Fear Survey (HFS II) At the Time of Enrollment

    Fear about hypoglycemia during 6 months prior to enrollment was evaluated using the Worry Scale of the HFS II. Responses to the 18-item questionnaire were recorded on a 0 to 4 scale, with 0=never, 1=rarely, 2=sometimes, 3=often, 4=almost always. The total score ranges from 0 to 72, with higher scores indicating increasing fear of hypoglycemia.

    Measured: Day of Enrollment

  6. Number of Participants Experiencing a Change in Body Weight in the 12 Months Prior to Enrollment

    Participants were asked to rate their weight change experience in the 12 months prior to enrollment as: weight increased, weight decreased, or weight remained stable.

    Measured: Up to 12 Months Prior to Enrollment

  7. Number of Participants Reporting Body Weight Fears in the 12 Months Prior to Enrollment

    On the day of enrollment, participants were asked to rate their fear of gaining weight in the 12 months prior to enrollment using a self-administered questionnaire. The questionnaire elicited responses to 3 statements (I worry about gaining weight; I worry that my diabetic treatment makes me gain weight; and I worry about not being able to stabilize my weight) and relied on a scale of 0 to 4, where 0=never, 1=rarely, 2=sometimes, 3=often, and 4=almost always.

    Measured: Up to 12 Months Prior to Enrollment

What does the primary outcome measure?

Number of Participants Experiencing Hypoglycemic Episodes in the 6 Months Prior to Enrollment (time frame: Up to 6 Months Prior to Enrollment). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
