Online vs. In-Person Diabetes Education: New Study Finds Both Work Equally Well

The OPTIM@TE trial compared two ways of delivering diabetes self-management education and support (DSMES)—the structured learning programs designed to help people with Type 1 diabetes manage their condition more effectively. Researchers wanted to know whether delivering the same educational content online was as effective as delivering it in person.

The study enrolled 51 adults with Type 1 diabetes whose blood sugar control was above goal (HbA1c of 7.5% or higher). Half attended an online program, and half attended an equivalent in-person program. Both programs used the same curriculum and aimed to provide at least 10 hours of education. Researchers tracked blood sugar control, continuous glucose monitor (CGM) data, weight, and other health measures for 12 months.

The primary finding was that HbA1c—the measure of average blood sugar control over three months—improved similarly in both groups. There was no meaningful difference between the online and in-person approaches at 12 months. This suggests that the format of delivery did not affect how well people's blood sugar control improved.

Other glucose-related measures tracked by CGM, as well as weight and metabolic markers, showed no significant differences between the two groups either. This consistency across multiple measures suggests that both educational formats had comparable overall effects on diabetes management.

While blood sugar outcomes were equivalent, the online group showed greater improvement in adherence to a Mediterranean-style diet than the in-person group. This was the only secondary outcome that showed a statistically significant difference between the two approaches. Researchers did not explain why the online format might have offered an advantage for nutrition learning, but this finding suggests that digital education may have particular strengths in certain areas.

An important limitation was that only about 41% of all participants completed the programs, regardless of whether they were online or in-person. This relatively low completion rate reflects a real-world challenge: structured diabetes education programs, even when proven effective, are not finished by many people who start them.

The study required participants to have access to a personal digital device in order to join the online program. This is a practical consideration that reflects broader equity issues in digital health—not everyone has equal access to devices or reliable internet.

This pilot study suggests that people with Type 1 diabetes can benefit from structured self-management education regardless of whether it is delivered online or in person. For those who prefer learning from home, have scheduling constraints, or face transportation barriers, online education appears to be a valid option that produces comparable results.

However, the modest completion rates in both groups highlight the importance of addressing barriers to finishing diabetes education—whether those barriers are time, motivation, accessibility, or other factors. Larger studies and longer follow-up will help clarify whether these findings hold over extended periods and in more diverse populations.
