(HealthDay News) — For patients with diabetes, personalized education and diabetes risk assessments performed during retinal ophthalmologic visits do not result in improved glycemic control, according to a study published in JAMA Ophthalmology.
Lloyd Paul Aiello, MD, PhD, from Harvard Medical School in Boston, and colleagues examined whether point-of-care HbA1c measurement and personalized diabetes risk assessments performed during retinal ophthalmologic visits improve glycemic control.
Investigators from 42 sites were randomly assigned to provide study-prescribed augmented diabetes assessment and education or usual care.
Participants were adults with type 1 or type 2 diabetes who were classified according to the frequency of follow-up care: those receiving a more-frequent-than-annual follow-up (502 control and 488 intervention participants) and those receiving annual follow-up (368 control and 388 intervention participants).
The researchers found that the mean changes in HbA1c wrere −0.1% and −0.3%, respectively, in the control and intervention groups at 1 year (P=.35) among participants with more-frequent-than-annual follow-up. The mean changes in HbA1c were 0.0% and −0.1%, respectively, for the control and intervention groups (P=.63) at 1 year among the cohort with annual follow-ups.
Similar results were seen for all secondary outcomes.
“These data suggest that optimizing glycemic control remains a substantive challenge requiring interventional paradigms other than those examined in our study,” the researchers wrote.
