Patient Variables Not Associated With HbA1c Targets
Lack of variation with patient characteristics suggests overreliance on a general approach.
(HealthDay News) – Patient variables seem not to be associated with hemoglobin A1c (HbA1c) targets, according to a study published in Diabetes Care.
Saeid Shahraz, MD, PhD, from Tufts Medical Center in Boston, and colleagues used data from the National Health and Nutrition Examination Survey to analyze patient-reported HbA1c targets set by physicians and whether there was a correlation between targets and patient characteristics. Data were included for 2641 individuals with self-reported diabetes, of whom 1782 responded to a question about HbA1c targets.
The researchers found that 54% of respondents reported a target; others reported that they did not know or that no target was set. Only 4% of the sample reported target HbA1c >7%. Of those reporting that a target was not set, 26% were older than 75 years. Of those who were not aware of their target, 70% were nonwhite. From 2005 to 2013 there was a decrease in the proportion responding that they did not know their target, from 30% to 10%. There were no correlations for variables representing demographics; medical history; biological, physical, and mental health; and health service use with reported target HbA1c.
"The lack of variation with patient characteristics suggests overreliance on a general approach, without consideration of individual variation in the risks and benefits (or patient preference) of tight control," the authors write.
