Diabetes and lipid control were not significantly improved with adherence information or motivational interviewing compared with usual care, according to study findings published in The Diabetes Educator.
L. Keoki Williams, MD, MPH, of the Center for Health Policy and Health Services Research at the Henry Ford Health System and colleagues evaluated adults from a health system in Michigan. Participants were using oral diabetes and lipid-lowering medications and had not met goals for HbA1c or LDL-cholesterol levels. Participants were randomly assigned into the following groups: usual care (n = 567), medication adherence information provided to physician (n = 569) or adherence information as well as motivational interviewing through trained staff members (n = 556). The primary outcomes measured were HbA1c and LDL-cholesterol levels.

Compared with usual care, neither intervention showed significantly different results after 18 months. Similarly secondary outcomes, including HbA1c and LDL-cholesterol levels at different time points, oral diabetes medication adherence and lipid-lowering medications adherence at 6, 12 and 18 months following randomization and rate of major atherosclerotic disease event by 18, 24 and 36 months following randomization, did not significantly differ for adherence information or adherence information with motivational interviewing compared with usual care.
“This study shows that neither providing [adherence information] to physicians nor combining [adherence information] to physicians with motivational interviewing support to patients had significant impacts on diabetes and lipid control when compared with usual care,” the researchers wrote. “Although poor participation precluded assessing the true efficacy of the intervention as designed, the intervention was ineffective on a population level despite the allocation of considerable resources.” – by Amber Cox
