Use of Diabetes Technology Is Lower Among Black, Hispanic Patients

A retrospective study of patients at a minority-serving, safety-net hospital showed low uptake of diabetes technology among black patients with type 1 diabetes, compared with their white counterparts.

The researchers also found lower usage of the technology among Hispanic patients, but the difference, compared with their white counterparts, was not statistically significant after adjustments for language, insurance, age, and income. Patients who identified as “other” also were less likely than white patients to use the technology, which included continuous glucose monitors and continuous subcutaneous insulin infusion devices.

The data differs from other, similar studies of technology use in patients with type 1 diabetes, because the study population, drawn from the Boston University Medical Center, is more diverse than other studies, as fewer than 50% of the participants were white, lead study author Kamonkiat Wirunsawanya, MD, said in a presentation during the annual meeting of the Endocrine Society, which was presented online this year. The actual meeting, scheduled for March 28-31 in San Francisco, was canceled because of COVID-19 concerns.

Dr. Wirunsawanya, an endocrinology fellow at Boston University Medical Center, and colleagues are now using questionnaires to try to identify specific patient and physician factors that might explain the differences in technology use.

“Once we know which factors could be a barrier to using the technology, we’ll be able to implement a strategy to increase use in those patients,” Dr. Wirunsawanya said in an interview. The issue could be a two-way street, he noted, because some providers may be uncomfortable using the technology, or may perceive minorities as less adept at using technology.

The study included 227 adult patients who were seen at the medical center between October 2016 and September 2017. The mean age was 39 years, and 59% were men. The mean duration of type 1 diabetes was 21 years, and 30% of the patients were overweight, 22% were obese, 80% spoke English, and 50% were on government insurance. In all, 43% of the patients were white, 25% were black, 15% were Hispanic, 2% were Asian, and 15% identified as other.

Patients who used technology had lower mean levels of hemoglobin A1c, compared with nonusers (8.27% vs. 9.49%, respectively). Those with government health insurance were less likely than those with private insurance to use technology (odds ratio, 0.43; 95% confidential interval, 0.25-0.74).

Overall, 26% of the patients used continuous subcutaneous insulin infusion devices. Of those, 43% were white, 10% black, 14% Hispanic, none were Asian, and 18% identified as other.

In addition, 30% of the patients used continuous glucose monitors; of those, 47% were white, 14% black, 23% Hispanic, 25% Asian, and none identified as other.

After adjustments for insurance and language, the researchers found that black patients were less likely to use technology than were the white patients (OR, 0.25; 95% CI, 0.11-0.53). The same was found for those who identified as other (OR, 0.33; 95% CI, 0.12-0.89). There were no significant differences in technology use between white and Asian patients. After adjustments, the researchers showed that fewer Hispanic patients used technology, compared with their white counterparts, but the difference was not statistically significant.

In a multivariable logistic regression model that adjusted for insurance and language, black patients had lower odds of using technology, compared with white patients (OR, 0.25; 95% CI, 0.11-0.53), as did those identifying as other (OR, 0.33; 95% CI, 0.12-0.89).

In an interview, Anne Peters, MD, director of clinical diabetes programs at the University of Southern California, Los Angeles, said that the study highlights a common problem with introducing technology to underserved populations. “These study [findings are] not at all surprising. It’s something that is a puzzle for those of us who work in the field of diabetes management in patients from underserved communities. Even if you can get access to the technology, even when I get them tools and native Spanish-speaking educators and people who should be able to teach them how to use the technology, the adoption of the technology has been really much less than would be expected,” said Dr. Peters, who is also a professor of medicine at USC and was not involved in the research.

Part of the problem may be lack of contact with health care services, she said. White children with type 1 diabetes are treated from an early age and learn how to manage daily blood sugar levels. They often grow up to embrace technology, even enthusiastically. But in some minority communities, diabetes is viewed as something to be hidden away. That cultural difference is also a frustrating barrier.

“What happens in more affluent groups is that people learn from their peers, and they see that [managing their blood sugar] is possible. One of my big beliefs is that the answer has to come from [the community]. … We need to get champions, people from the community who use these tools, to encourage others, and that’s hard to do because type 1 diabetes is such a small subset of the people with diabetes who are [black] or Latino,” said Dr. Peters.

Ultimately, the solution will require a shift in messaging by finding a way to help communities look differently at diabetes and its treatment. “There’s something that must come educationally and culturally that I’ve not figured out [yet]. I can get resources and fight for them, but we have to figure out how to make [technology] part of that culture, and I don’t know that we’ve done that,” she said.

Dr. Wirunsawanya reported no financial conflicts of interest. Dr. Peters has been on an advisory panel for Abbott Diabetes Care and has received research funding from Dexcom.

Dr. Wirunsawanya and colleagues’ research will be published in a special supplemental issue of the Journal of the Endocrine Society. In addition to a series of news conferences on March 30-31, the society will host ENDO Online 2020 during June 8-22, which will present programming for clinicians and researchers.
