Targeting Technology in Underserved Adults With Type 1 Diabetes: Effect of Diabetes Practice Transformations on Improving Equity in CGM Prescribing Behaviors

OBJECTIVE

Continuous glucose monitoring (CGM) is associated with improved outcomes in type 1 diabetes, but racial-ethnic disparities exist in use. We were interested in examining whether addressing structural health care barriers would change provider prescribing behaviors to make CGM access more equitable.

RESEARCH DESIGN AND METHODS

From January 2019 to December 2021, we used multilevel stakeholder input to develop and implement several non-grant-funded practice transformations targeted toward equity, which included 1) developing a type 1 diabetes clinic, 2) conducting social needs assessments and management, 3) training support staff to place trial CGMs at the point of care, 4) optimizing prescription workflows, and 5) educating providers on CGM. Transformations were prioritized based on feasibility, acceptability, and sustainability. To examine effect on prescribing behaviors, we collected monthly aggregate data from the electronic medical record and performed multiple linear regression to examine and compare change in CGM prescriptions over the 3 years of transformation.

RESULTS

In total, we included 1,357 adults with type 1 diabetes in the analysis (mean ± SD age 38 ± 18 years; 30% Black [n = 406], 45% Hispanic [n = 612], 12% White [n = 164]; and 74% publicly insured [n = 1,004]). During the period of transformation, CGM prescription rates increased overall from 15% to 69% (P < 0.001). Improvements were seen equally among Black (12% to 72%), Hispanic (15% to 74%), and White adults (20% to 48%) (between-group P = 0.053).

CONCLUSIONS

Diabetes practice transformations that target equity, offload provider burdens, and focus on feasible sustainable stakeholder-driven solutions can have powerful effects on provider prescribing behaviors to reduce root causes of inequity in CGM among underserved adults with type 1 diabetes. Continued focus is needed on upstream determinants of downstream CGM use.

Achieving Equity in Diabetes Research: Borrowing From the Field of Quality Improvement Using a Practical Framework and Improvement Tools

There are limited tools to address equity in diabetes research and clinical trials. The T1D Exchange has established a 10-step equity framework to advance equity in diabetes research. Herein, the authors outline this approach and expand on its practical application.

Solutions to Address Inequity in Diabetes Technology Use in Type 1 Diabetes: Results from Multidisciplinary Stakeholder Co-creation Workshops

Background: Racial-ethnic inequity in type 1 diabetes technology use is well documented and contributes to disparities in glycemic and long-term outcomes. However, solutions to address technology inequity remain sparse and lack stakeholder input. Methods: We employed user-centered design principles to conduct workshop sessions with multidisciplinary panels of stakeholders, building off of our prior study highlighting patient-identified barriers and proposed solutions. Stakeholders were convened to review our prior findings and co-create interventions to increase technology use among underserved populations with type 1 diabetes. Stakeholders included type 1 diabetes patients who had recently onboarded to technology; endocrinology and primary care physicians; nurses; diabetes educators; psychologists; and community health workers. Sessions were recorded and analyzed iteratively by multiple coders for common themes. Results: We convened 7 virtual 2-h workshops for 32 stakeholders from 11 states in the United States. Patients and providers confirmed prior published studies highlighting patient barriers and generated new ideas by co-creating solutions. Common themes of proposed interventions included (1) prioritizing more equitable systems of offering technology, (2) using visual and hands-on approaches to increase accessibility of technology and education, (3) including peer and family support systems more, and (4) assisting with insurance navigation and social needs. Discussion: Our study furthers the field by providing stakeholder-endorsed intervention ideas that propose feasible changes at the patient, provider, and system levels to reduce inequity in diabetes technology use in type 1 diabetes. Multidisciplinary stakeholder engagement in disparities research offers unique insight that is impactful and acceptable to the target population.

The Knowledge Assessment of Renal Transplantation (KART) 2.0: Development and Validation of CKD and Transplant Knowledge Scales

BACKGROUND AND OBJECTIVES

Many individuals with kidney disease, particularly those belonging to racial and ethnic minority groups and whose primary language is not English, lack knowledge related to kidney disease symptoms, physiologic functions of the kidney, and benefits and risks of kidney transplantation. Valid instruments to assess patients' knowledge of CKD and kidney transplantation are needed.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Using a sample of 977 patients with stages 3-5 CKD in the Kaiser Permanente health system, we developed the Knowledge Assessment of Renal Transplantation (KART) 2.0 instrument. We conducted cognitive interviews followed by item response theory (IRT) to reduce 48 candidate items. Construct validity was tested by examining differences in scores between patients who spent <1 and ≥1 hour receiving CKD and transplant education.

RESULTS

Cognitive interviews modified four items and omitted 11. IRT analyses resulted in two scales: the KART 2.0-Transplant Knowledge Scale (16 items; Cronbach's α=0.8) and the KART 2.0-CKD Knowledge Scale (nine items; Cronbach's α=0.79). Differential item functioning showed that the scales were unbiased to capture knowledge across self-identified race, primary language, CKD stage, and sex. Both scales distinguished patients who had spent <1 and ≥1 hour speaking with health professionals (effect size [ES]=0.33 [transplant], 0.54 [CKD]; P<0.001 for both), reading about kidney disease (ES=0.45 [transplant], 0.62 [CKD]; P<0.001), reading about kidney transplantation (ES=0.67 [transplant], 0.69 [CKD]; P<0.001), and reading about living donor kidney transplant (ES=0.76 [transplant], 0.62 [CKD]; P<0.001).

CONCLUSIONS

The KART 2.0 is a valid tool to assess patients' knowledge of CKD and kidney transplantation.

COVID-19 and metabolic diseases: a heightened awareness of health inequities and a renewed focus for research priorities

Chronic metabolic disorders such as diabetes and obesity are major public health issues in the United States. However, significant disparities in their prevalence and incidence place a greater burden on US racial and ethnic minority groups, contributing to worse COVID-19 outcomes in many. Improving treatment and prevention of diabetes and obesity is critical to the NIDDK. In this Perspective, we will review the burden of metabolic diseases in the United States, the observed disparities for metabolic diseases in relation to COVID-19, and research opportunities to address underlying causes of metabolic diseases, their associated health disparities, and COVID-19.
