Clinical Trial Summary
Lower socioeconomic status (SES) individuals with type 1 diabetes have poorer outcomes than
wealthier patients and part of this disparity comes from a lack of tools and knowledge about
how to teach these patients on the technologies other patients take for granted. Therefore,
this is a study designed to develop and test low literacy English/Spanish language teaching
tools for patients with type 1 diabetes treated with varying types of technology in the Los
Angeles County healthcare system. The aims are to:To reduce health disparities for
underserved adults with diabetes on multiple daily injection (MDI) therapy using vials and
syringes through the use of a simplified lower literacy, culturally and language appropriate
approach to teach, implement and follow these individuals started on insulin pens and
pumps/continuous subcutaneous insulin infusion (CSII); To show no increase in rates of
diabetic ketoacidosis (DKA) or severe hypoglycemia when using CSII or pen therapy compared to
baseline rates; To reduce time spent in hyper and hypoglycemic ranges, as well as glycemic
variability, as measured by blinded continuous glucose monitoring (CGM); Reduce psychological
distress due to diabetes and improve health-related quality of life, as measured by validated
distress and quality of life scales. Secondary Aims include: Reduction in A1C levels with
CSII/pen therapy compared to standard MDI treatment; and to perform a cost-analysis of the
process of implementation to improve the generalizability of the model.
Description:
SUMMARY OF STUDY RATIONAL - Lower socioeconomic status (SES) individuals with type 1 diabetes
(T1D) have poorer outcomes than wealthier patients and part of this disparity comes from a
lack of tools and knowledge about how to teach these patients on the technologies other
patients take for granted. Until recently many of these lower SES individuals did not have
access to health insurance, but with the implementation of the Affordable Care Act the group
with the greatest expansion of coverage is the young adult age group (ages 18 - 34),
particularly in the Latino community. Increased insurance allows for access to newer
technology including insulin pens and pumps. As these patients have not had access to such
devices, low literacy educational tool are necessary for safe and efficient utilization.
Therefore, this is a study designed to develop and test low literacy English/Spanish language
teaching tools for patients with type 1 diabetes treated with varying types of technology in
the Los Angeles County (LAC) healthcare system. This study is a single center pilot study and
by the nature of our clinic setting it cannot be a randomized controlled trial - it is more
of a naturalistic experiment comparing each patient to their prior state of glycemic control
with their status after the educational intervention using low-literacy educational materials
has been applied.
INTERVENTION - Baseline Visit: Participants will sign informed consent, complete
questionnaires, and measure HbA1C. Those opting to do so will start a continuous glucose
monitor (CGM) sensor. All patients will be provided the written low literacy teaching tools
in the language of their choice.
CGM Visit - for those opting to wear CGM will occur at Week 2 where 14 days of CGM data will
be downloaded from participants' device.
Education Sessions: Educational sessions will be conducted using the low-literacy tools we
created. Classes will be available on Fridays during T1D Clinic and on Saturdays to maximize
participation. Classes will be every two weeks for approximately 3 months. Classes will be
approximately 1 ½ hours in duration. Patients will be encouraged but not required to attend
the classes. However, those starting on the pen and/or pump will be asked to attend the
relevant sessions to prepare them for use of the technology.
Educational Sessions:
Session 1 - Basics of type 1 management Session 2 - Carbohydrate counting, Session 3 -
Insulin self- adjustment, Session 4 - Sick day rules and physical activity dose adjustments
Session 5 - Starting the insulin pen (for pen users) or pump (for pump users) Session 6 -
Trouble shooting the pump (for pump users)
Phone Calls - Each patient will be contacted monthly (baseline month up to month 3 visit) by
the diabetes educator to follow-up on questions and concerns regarding their diabetes
management.
Clinic Visit 2 - post education visit will occur at 3 months. Questionnaires will be
administered, A1C measured and CGM data and compare to baseline.
Clinic Visit 3 - will occur at 6 months. Questionnaires will be administered, A1C measured
and CGM data and compare to baseline.
Clinic Visit 4 -will occur at 12 months. Questionnaires will be administered, A1C measured
and CGM data and compare to baseline and 6 months.
DATA COLLECTION AND TESTING PROCEDURES (Baseline, 6 months and 12 months) HbA1c - HbA1c will
be obtained using the point of care Siemens DCA Vantage Analyzer.
Continuous Glucose Monitoring (CGM)- A commercially available DexCom G5 or Libre device will
be provided and a sensor will be inserted. The participant will receive instructions on
calibration, insertions, maintenance, use, and removal of the sensor.
T1D REDEEM Diabetes Distress Questionnaire- The T1D REDEEM Diabetes Distress Questionnaire
measures several dimensions of stress related to having type 1 diabetes. It consists of the
following 7 subscales: Subscale 1 - Powerlessness (5 items); Subscale 2 - Management Distress
(4 items); Subscale 3 - Hypoglycemia Distress (4 items); Subscale 4 - Negative Social
Perceptions (4 items); Subscale 5 - Eating Distress (3 items); Subscale 6 - Physician
Distress (4 items); Subscale 7 - Friend/Family Distress (4 items). Each question has a
6-choice Likert response format. Administration time is approximately 10 minutes.
Hypoglycemia Fear Survey - The Hypoglycemia Fear Survey measures several dimensions of fear
of hypoglycemia among adults with type 1 diabetes. It consists of a 10-item Behavior subscale
that measured behaviors involved in avoidance and over-treatment of hypoglycemia and a
13-item Worry subscale that measures anxiety and fear surrounding hypoglycemia, each with a
5-choice Likert response format. Administration time is approximately 10 minutes.
Simplified Diabetes Knowledge Test -The Simplified Diabetes Knowledge Test consists of 23
knowledge test items developed by the Michigan Diabetes Research Training Center (MDRTC).
These items represent a test of general knowledge of diabetes and are answered in a
true/false/don't know format. The psychometric properties provide information regarding the
reliability of the various groups of items, as well as a difficulty index (percent of
patients who scored this item correctly), and an item to group total correlation for each
item. These data can be reported when describing the use of the test. Administration time is
approximately 15 minutes.
Assessment of Sever Hypoglycemia and Diabetic Ketoacidosis -The Assessment of Severe
Hypoglycemia and Diabetic Ketoacidosis is an interviewer administered survey assessing if the
subject had any episodes of severe hypoglycemia and/or diabetic ketoacidosis since their last
study visit. Events are recorded to assess frequency, as is type of assistance required to
treat the event. Administration time is approximately 5 minutes.
