Type 2 Diabetes Clinical Trial
Official title:
Improving Care for Primary Care Patients With Diabetes and Poor Literacy and Numeracy Skills
The aim of this research will be to perform a small randomized controlled trial (RCT) of a new diabetes educational intervention that teaches self-management skills that compensate for poor numeracy skills among a sample of primary care patients with type 2 diabetes and low literacy and/or numeracy.
Results of the National Adult Literacy Survey (NALS) suggest that over 90 million adult
Americans have poor quantitative skills. Numeracy, the ability to understand and use numbers
and math skills in daily life, may be particularly important to patients with diabetes
because caring for diabetes often requires self-management skills that rely on the daily
application of math skills, such as counting carbohydrates, interpreting blood glucose
monitoring, applying sliding scale insulin regimens, and calculating insulin to carbohydrate
ratios. Presumably diabetes patients with poor numeracy have more difficulty with
self-management and are at risk for poorer clinical outcomes, but to date, there are no
published studies that rigorously examine the role of numeracy in diabetes. We have recently
completed the initial development of a new scale to measure numeracy in patients with
diabetes: the Diabetes Numeracy Test (DNT).
The aim of this research will be to perform a small randomized controlled trial (RCT) of a
new diabetes educational intervention that teaches self-management skills that compensate
for poor literacy and numeracy skills among a sample of patients with type 2 diabetes and
low numeracy or literacy skills. We hypothesize that a group of patients with poor literacy
and/or numeracy who are taught self-management skills that accommodate their poor numeracy
will have: (1) improved treatment satisfaction and perceived self-efficacy, (2) improved
performance in self-management tasks, and (3) improved glycemic control compared to a
control group that receives usual education and care.
