Study of Diabetes Self-Management Program Finds Parity Between In-Person, Digital Formats

Mary Caffrey
A diverse group of 1242 patients received diabetes self-management education either in-person or online and achieved lowered blood glucose and depression levels, had fewer symptoms of hypoglycemia, and exercised more.
Through the Stanford study, 1010 people took part in the digital format, and 232 took part in face-to-face formats at 3 sites. Because this was a translation study, researchers wrote, the population was not screened to isolate participants with certain symptoms or clinical factors. Thus, some of the subgroups analyses looked at only those in the population who demonstrated problems in the variable of interest. Researchers found:
  • Among the patients providing blood samples (489), 20% had a glycated hemoglobin (A1C) of 9% or higher at baseline. At the 6-month follow-up, the share fell to 15.3%, and the mean reduction for those with A1C of 9% or higher was –0.93%.
  • To evaluate depression, 877 patients were given the 8-question Patient Health Questionnaire. At baseline, 22% had symptoms indicating clinical depression, and at 6 months that share had fallen to 16.3%.
  • At baseline 38.4% of 865 of the patients had 2 or more symptoms of hypoglycemia; by the 6-month mark, the share was reduced to 32.4%.
  • At baseline, 35% of the patients were nonadherent; by 6 months, 29.4% were.
  • When the study began, 23.2% of 876 patients reported having no aerobic exercise. At 6 months, this was down to 18.4%, with a mean increase in exercise of 43 per week among those who reported limited or no exercise before the intervention.

There was a very slight uptick in A1C (0.05%) among those who started below 9%, and there was some slacking off of exercise for those who were faring well before the intervention. However, the researchers wrote, “the improvements for the less well-off group were much greater than any negative changes for those who had been doing well at baseline.”

Notably, there were no significant differences in outcomes between those who received in-person and digital formats, except for some advantage in sleep for those in the face-to-face groups. While overall the participants were well-educated women, the digital format group was statistically more likely to be male—which is important for health plans, since diabetes programs report that it is harder to get men to take part.

“We clearly achieved our goal in showing that evidence-based diabetes self-management programs are equally effective for a larger, more diverse group of people who would typically enroll through their health plans,” said Lorig.

Also noteworthy for payers: the researchers observe that with an average participation time of 2.5 hours per week, the total time of the in-person workshops exceeds the 10 hours typically covered by insurance. But less time than that is typically ineffective, they write.

“This study confirms previous evidence empowering individuals to self-manage their condition levels to improved health outcomes,” said Neal Kaufman, MD, MPH, chief medical officer of Canary Health. “These results should be a clear call for broader clinical acceptance of digital health self-management as a crucial part of transforming healthcare to a value-based model.”
