Health Care Disparities in Outpatient Diabetes Management During the Coronavirus Disease 2019 Pandemic: Where Do We Stand Now?

Objective: We examined diabetes outpatient management during the first 2 years of the Coronavirus Disease 2019 pandemic in an endocrinology practice with a focus on health care disparities in outcomes.

Methods: We conducted a retrospective cohort study examining adults with diabetes during 3 time periods: T1 (March 2019-February 2020), T2 (March 2020-February 2021), and T3 (March 2021-February 2022). Clinical outcomes included body mass index (BMI), systolic blood pressure (SBP), Hemoglobin A1c (HgbA1c), low-density lipoprotein cholesterol (LDL), and urine albumin:creatinine ratio. Appointment types (virtual vs in-person) were also collected.

Results: Frequencies of HgbA1c, BMI, and SBP measurements reduced by 36.0%, 46.3%, and 48.5% in T2, respectively, and remaining 8.7% (HgbA1c), 13.4% (BMI), and 15.2% (SBP) lower at the end of the study period (P < .001) compared to prepandemic levels. However, the average HgbA1c and LDL slightly improved. Clinic appointments per patient increased during the pandemic, fueled by telehealth utilization. Women had fewer in-person visits during T2, those older than 65 had better HgbA1c, and the most socioeconomically deprived group had the worst HgbA1c during every time period. In addition, black patients had worse HgbA1c, LDL, and SBP values throughout the study, which did not worsen over the pandemic.

Conclusion: While the frequency of health measurements had not fully recovered 2 years into the pandemic, this did not translate to worse diabetes management or a widening of pre-existing disparities. Our study emphasizes the role of equitable health care in minimizing inequalities in diabetes, particularly during times of crisis.
