Diabetes Complications in Racial and Ethnic Minority Populations in the USA

Ethnicity, Skin Tones, and Cultural Considerations in Wound Care: Challenges and Solutions

Wound care patients often have a variety of chronic medical conditions that result in poor outcomes, such as delayed healing and nontraumatic limb loss. Many of these suboptimal patient outcomes result from healthcare disparities linked to social determinants of health (SDOH). Race and ethnicity influence SDOH by impacting patients' access to consistent quality healthcare. Understanding and addressing why and how ethnic and cultural factors influence SDOH is crucial for making substantial changes.

Early combination therapy with SGLT2i and GLP-1 RA or dual GIP/GLP-1 RA in type 2 diabetes

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-Like peptide-1 receptor agonists (GLP-1 RA) are recommended in people with type 2 diabetes (T2D) for glycaemic control and for people with high cardiovascular risk. However, current guidelines do not specifically address the role of initial early combination therapy with SGLT2i and GLP-1 RA or dual gastric inhibitory polypeptide (GIP)/GLP-1 RA, but rather sequential initiation with either in T2D. This review synthesizes the available evidence on the use of SGLT2i and GLP-1-based therapies for T2D and provides a rationale for their combination. The combination of SGLT2i with GLP-1-based therapies addresses complementary pathophysiological mechanisms and enhances efficacy in achieving target haemoglobin A1C (HbA1c) levels. SGLT2i and GLP-1 RA also have been shown to prevent complications of T2D. While both classes reduce adverse cardiorenal events, SGLT2i has a predominant effect on prevention of kidney dysfunction and heart failure, whereas GLP-1 RA has a more marked effect on the risk of atherosclerotic cardiovascular disease. Both drug classes have favourable safety profiles. Finally, weight loss with combination therapy may have disease-modifying effects that may reverse T2D progression. We propose that the combination of SGLT2i with GLP-1 RA or dual GIP/GLP-1 RA should be considered for most patients with T2D who do not have contraindications.

Data-driven Cluster Analysis Reveals Increased Risk for Severe Insulin-deficient Diabetes in Black/African Americans

CONTEXT

Diabetes is a heterogenic disease and distinct clusters have emerged, but the implications for diverse populations have remained understudied.

OBJECTIVE

Apply cluster analysis to a diverse diabetes cohort in the US Deep South.

DESIGN

Retrospective hierarchical cluster analysis of electronic health records from 89 875 patients diagnosed with diabetes between January 1, 2010, and December 31, 2019, at the Kirklin Clinic of the University of Alabama at Birmingham, an ambulatory referral center.

PATIENTS

Adult patients with International Classification of Diseases diabetes codes were selected based on available data for 6 established clustering parameters (glutamic acid decarboxylase autoantibody; hemoglobin A1c; body mass index; diagnosis age; HOMA2-B; HOMA2-IR); ∼42% were Black/African American.

MAIN OUTCOME MEASURE(S)

Diabetes subtypes and their associated characteristics in a diverse adult population based on clustering analysis. We hypothesized that racial background would affect the distribution of subtypes. Outcome and hypothesis were formulated prior to data collection.

RESULTS

Diabetes cluster distribution was significantly different in Black/African Americans compared to Whites (P < .001). Black/African Americans were more likely to have severe insulin-deficient diabetes (OR, 1.83; 95% CI, 1.36-2.45; P < .001), associated with more serious metabolic perturbations and a higher risk for complications (OR, 1.42; 95% CI, 1.06-1.90; P = .020). Surprisingly, Black/African Americans specifically had more severe impairment of β-cell function (homoeostatic model assessment 2 estimates of β-cell function, C-peptide) (P < .001) but not being more obese or insulin resistant.

CONCLUSION

Racial background greatly influences diabetes cluster distribution and Black/African Americans are more frequently and more severely affected by severe insulin-deficient diabetes. This may further help explain the disparity in outcomes and have implications for treatment choice.

Burden of vascular risk factors by age, sex, ethnicity and deprivation in young adults with and without newly diagnosed type 2 diabetes

AIMS

Do associations between age at diagnosis of type 2 diabetes and vascular risk factors vary by ethnicity and deprivation?

METHODS

Utilising the Clinical Practice Research Datalink, we matched 16-50-year-old individuals with newly diagnosed type 2 diabetes to ∼10 individuals without using sex, age and primary care practice. Differences in BMI, obesity, LDL-cholesterol, HbA1c, and hypertension between individuals with vs without type 2 diabetes across sex, age, ethnicity and deprivation quintiles were explored using generalised linear models.

RESULTS

We included 108,061 individuals (45.6% women) with newly diagnosed type 2 diabetes and 829,946 controls. BMI, obesity, LDL-cholesterol, and hypertension were higher in individuals with vs without type 2 diabetes. Across both sexes, all ethnic groups and deprivation quintiles, these differences were larger with an earlier age, particularly for BMI and obesity. Association between age and HbA1c were variable across subgroups. Differences in BMI, obesity, and hypertension (individuals with vs without diabetes) were largest in White individuals and with less deprivation.

CONCLUSIONS

The increased vascular risk phenotype associated with an earlier age of diagnosis of type 2 diabetes was consistent across ethnic and deprivation groups. Population-based strategies are needed to address the risk associated with early-onset type 2 diabetes, especially weight-management-based strategies.

Assessing the Risks and Cultural Relativity of Diabetes in Black Individuals of African Caribbean Ancestry (ACB) Aged 18-39 Years in Toronto

Context: Diabetes rates are high in Black and some other ethnic communities, often leading to more severe complications. We conducted a study to identify the prevalence and risk of diabetes among African Caribbean Black (ACB) individuals aged 18-39 and to assess the sensitivity of glycated hemoglobin (HbA1c) compared to an oral glucose tolerance test (OGTT) to diagnose diabetes. Methods: In this mixed-methods study, maximum variation sampling was used to recruit 272 ACB participants from fourteen African and five Caribbean countries from Toronto. Participants' height, weight, waist circumference, HbA1c, OGTT, demographic, and behavioural data were collected. SPSS was used to analyze the quantitative data. This study used descriptive statistics for frequency distribution and cross-tabulation while inferential statistics (regression, ANOVA, factor analysis, etc.) were used for relational analysis. Because of the small sample size, qualitative data were analyzed manually using the charting technique. Results: This study found that 1.5% of participants had diabetes, 9.2% had prediabetes, and 44.9% were at risk of developing diabetes. The mean value of HbA1c, FBS, and 2hPG was 5.5%, 4.8 mmol/L, and 5.7 mmol/L, respectively. The mean BMI was 28.2 kg/m2, and the waist circumference was 85.8 cm. This study found a correlation between glucose intolerance and increasing body mass index (BMI) and waist circumference (WC). Dietary habits, physical inactivity, and mental health challenges were risk factors among the participants. HbA1c was found to be a more sensitive and culturally acceptable screening measure than OGTT in diagnosing diabetes. Conclusions: ACB individuals are at high risk of having diabetes, requiring culturally tailored peer-based health promotion strategies to reduce diabetes prevalence and risk. HbA1c is a culturally acceptable and statistically more capable measure than OGTT in identifying individuals with prediabetes. Further longitudinal research is needed.

Oxidative Stress and Cardiovascular Complications in Type 2 Diabetes: From Pathophysiology to Lifestyle Modifications

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder that significantly increases the risk of cardiovascular disease, which is the leading cause of morbidity and mortality among diabetic patients. A central pathophysiological mechanism linking T2DM to cardiovascular complications is oxidative stress, defined as an imbalance between reactive oxygen species (ROS) production and the body's antioxidant defenses. Hyperglycemia in T2DM promotes oxidative stress through various pathways, including the formation of advanced glycation end products, the activation of protein kinase C, mitochondrial dysfunction, and the polyol pathway. These processes enhance ROS generation, leading to endothelial dysfunction, vascular inflammation, and the exacerbation of cardiovascular damage. Additionally, oxidative stress disrupts nitric oxide signaling, impairing vasodilation and promoting vasoconstriction, which contributes to vascular complications. This review explores the molecular mechanisms by which oxidative stress contributes to the pathogenesis of cardiovascular disease in T2DM. It also examines the potential of lifestyle modifications, such as dietary changes and physical activity, in reducing oxidative stress and mitigating cardiovascular risks in this high-risk population. Understanding these mechanisms is critical for developing targeted therapeutic strategies to improve cardiovascular outcomes in diabetic patients.

"Life with Diabetes": A Pilot Study on an Experiential Continuous Glucose Monitoring Curriculum for Resident Physicians

BACKGROUND

The use of technology in diabetes mellitus (DM) management has been growing. The indications and coverage for continuous glucose monitoring (CGM) have increased. Primary care (PC) clinics, including resident continuity clinics, are the frontline for DM management; however, they struggle to adopt CGM.

AIM

To implement a CGM curriculum to resident physicians to improve knowledge and confidence.

SETTING

An internal medicine (IM) resident PC clinic in an urban academic medical institution.

PARTICIPANTS

Twenty-four IM residents.

DESCRIPTION

We designed a curriculum that included a lecture about CGM indications, interpretation, ordering, and insurance consideration; and a voluntary, experiential learning module in which the residents wore a CGM.

EVALUATION

We conducted a retrospective pre-post survey with a 4-point Likert scale. Average self-reported scores in knowledge increased for CGM (1) indications from 1.85 to 3.45, (2) ordering from 1.35 to 3.05, (3) functioning from 2.20 to 3.50, and (4) data interpretation from 1.85 to 3.25 (all p < 0.0001). Confidence for "describing CGM monitoring" and "fielding questions about CGM" increased from 2.25 to 3.65 (p < 0.0001) and 1.90 to 3.30 (p < 0.0001).

DISCUSSION

Given the demand for DM management in the PC setting, this targeted CGM curriculum has promise to help residents adopt CGM into their practice.

Comorbid Diabetes Is Associated With Dyspnea Severity and Cardiometabolic Biomarkers in Black Adults With Heart Failure

BACKGROUND

Comorbidities such as Type 2 diabetes mellitus significantly and adversely influence heart failure outcomes, especially in Black adult populations. Likewise, heart failure has a negative effect on diabetes and cardiometabolic outcomes. Dyspnea, a common symptom of heart failure, often correlates with disease severity and prognosis. However, the relationship between comorbid diabetes, dyspnea severity, and cardiometabolic biomarkers in Black adults with heart failure remains understudied.

OBJECTIVES

The purpose of this pilot study was to examine differences in the distressing heart failure symptom of dyspnea and in cardiometabolic and inflammatory biomarkers in Black adults living with heart failure with and without diabetes.

METHODS

Black adults with heart failure were enrolled in this cross-sectional pilot study. Cardiometabolic and inflammatory biomarkers were measured via multiplex immunoassay. Univariate general liner models were used to identify group differences between persons with heart failure with comorbid diabetes and those without, controlling for age, sex, and comorbid burden.

RESULTS

Participants were mostly female with a mean age of 55 years and mean left ventricular ejection fraction of 33%. Participants with diabetes exhibited higher dyspnea scores compared to those without diabetes, indicating greater symptom burden. Moreover, individuals with comorbid diabetes demonstrated higher levels of cardiometabolic and inflammatory markers.

DISCUSSION

Comorbid diabetes was associated with higher dyspnea severity and adverse cardiometabolic profiles in Black adults with heart failure. These findings underscore the importance of targeted interventions addressing diabetes management and cardiometabolic risk factors to improve symptom control and outcomes in this high-risk population. Further research is warranted to elucidate the underlying mechanisms and develop tailored therapeutic strategies for managing comorbidities in persons with heart failure, particularly in minoritized communities.

Characterizing syndemic HIV risk profiles and mHealth intervention acceptability among patients in the emergency department

Syndemic theory proposes that co-occurring, mutually reinforcing psychosocial challenges (mental health, substance use, minority stress [discrimination/stigma], abuse, unmet basic needs) drive HIV risk behavior and create barriers to care for marginalized populations. It is thus necessary to address this holistic, complex picture in HIV prevention. Emergency department (ED) visits are a prime opportunity to engage key risk groups, given their low engagement in regular clinic-based care and high utilization of drop-in care via EDs. Yet, EDs are overburdened and under-resourced; mHealth may be a vehicle for intervention delivery in this context. This study aimed to 1) characterize demographics, syndemic profiles, and HIV risk behavior among ED patients and 2) assess the acceptability of addressing syndemic issues, particularly via an mHealth approach, in the ED. A sample of N = 198 ED patients with an indication of HIV risk completed a cross-sectional psychosocial assessment. Descriptive statistics and bivariate correlations between syndemic issues were examined. Patients presenting to the ED reported marginalized identities and complex syndemic profiles including mental health issues (77%), at risk substance use (30%), childhood abuse (35%), adult abuse (31%), minority stress (63%), and unmet basic needs (37%). Over half the sample reported at least three syndemic issues (54%). All syndemic issues were significantly correlated with each other, supporting a synergistic nature. The sample reported indicators of HIV risk including lack of PrEP awareness (33%)/uptake (94%), condomless sex (37%), and not testing for HIV (41%). Majority reported syndemic profiles have never been addressed in the ED (71%), think it would be helpful (88%), and willing to utilize mHealth during an ED visit (76%). The current study provides information to guide next steps for ED-based point-of-care HIV prevention, and more broadly, working towards equitable HIV prevention services reaching those missed by existing interventions.

Nutritional and Inflammatory Aspects of Low Parathyroid Hormone in Maintenance Hemodialysis Patients-A Longitudinal Study

BACKGROUND

Low serum parathyroid hormone (PTH) is an accepted marker for adynamic bone disease which is characterized by increased morbidity and mortality in maintenance hemodialysis (MHD) patients. In light of the known cross-sectional associations between PTH and malnutrition-inflammation syndrome, we aimed to examine the longitudinal associations between PTH with changes in nutritional and inflammatory parameters and clinical outcomes in MHD patients with low PTH.

METHODS

This historical prospective and longitudinal study analyzed a clinical database at a single hemodialysis center, containing the medical records of 459 MHD patients (mean age of 71.4 ± 12.9 years old, 171 women), treated between the years 2007-2020. Bone turnover, nutritional and inflammatory marker levels were recorded at 0, 6, 12, 18, 24, 30, and 36 months followed by a median of 24 additional months of clinical observations. According to previous use of vitamin D analogs and/or calcium-sensing receptor agonists, the study participants were divided into treatment-related and disease-related groups. A linear mixed effects model was adjusted for baseline demographics and clinical parameters.

RESULTS

Of 459 MHD patients, 81 (17.6%) had PTH lower than 150pg/mL. Among them, 30 patients had treatment-related and 51 had disease-related low PTH. At baseline, MHD patients with treatment-related low PTH had a higher rate of diabetes compared to the disease-related group. In a linear mixed effects model, increased PTH over time was associated with decreased levels of alkaline phosphatase and C-reactive protein and with increased hemoglobin and albumin, but not the geriatric nutritional risk index at 3-year follow-up. The survival rate did not differ between the groups, with the risk of hospitalizations due to fractures being higher (HR: 4.04 with 95% CI: 1.51-10.8) in the disease-related group. Statistical significance of this association was abolished after adding C-reactive protein or alkaline phosphatase to the multivariate models.

CONCLUSIONS

Low serum PTH in MHD patients behaves differently depending on its cause, with a higher risk of fractures in the disease-related group. This association is dependent on inflammation. Our results should be verified in larger epidemiological studies.

Sanctuary policies and type 2 diabetes medication prescription trends among community health center patients

Immigrants in the United States are at increased risk of diabetes-related complications due to delayed diagnoses compared with US-born individuals. Immigration-related federal policies may support immigration enforcement activities and restrict some immigrants' access to health insurance and other publicly funded resources. Conversely, state and county-level sanctuary policies may reduce the fear of deportation and increase mobility in the community, improving the accessibility of essential pharmacological treatment for type 2 diabetes patients. This retrospective cohort study estimated the odds of receiving glucose-lowering medication prescriptions by the county's sanctuary policy environment for patients within a nationwide network of community health centers. We did not find statistically significant associations between sanctuary policies and annual prescription rates. The associations were not modified by nativity or race/ethnicity. Notably, compared to US-born patients, immigrants had higher odds of receiving prescriptions regardless of the sanctuary policy environment, emphasizing other potential influences on the receipt of anti-diabetes prescriptions for community health center patients.

Persistent organic pollutants and endogenous sex-related hormones in Hispanic/Latino adults: The Hispanic Community health study/study of Latinos (HCHS/SOL)

BACKGROUND

Previous studies have demonstrated associations of persistent organic pollutants (POPs) with sex-related hormones; however, findings were inconsistent. Sex-specific impacts and pathways through which adiposity influences associations are not completely understood. We sought to evaluate sex-specific associations of POPs serum concentration with sex-related hormones and to explore pathways through which adiposity may modify associations.

METHODS

We studied 1073 men and 716 postmenopausal women participating in the "Persistent Organic Pollutants, Endogenous Hormones, and Diabetes in Latinos" ancillary study which is a subcohort of the "Hispanic Community Health Study/Study of Latinos." We use baseline examination data collected from 2008 to 2011 to investigate associations between eight organochlorine pesticides (OCPs), five polychlorinated biphenyls (PCB) groups, sum of polybrominated diphenyl ethers and polybrominated biphenyl 153 on sex hormone binding globulin (SHBG) and various sex-related hormone levels. We examined associations cross-sectionally using linear and logistic regression models adjusted for complex survey design and confounders.

RESULTS

PCBs and select OCPs were associated with increased SHBG in women and decreased estradiol (E2) and/or bioavailable E2 in men. For instance, per quartile increase in serum concentrations of ∑PCBs and oxychlordane were associated with decreased levels of E2 (β = -6.36 pmol/L; 95% CI: 10.7,-2.02 and β = -5.08 pmol/L; 95% CI: 8.11,-2.05) and bioavailable E2 (β = -4.48 pmol/L; 95% CI: 7.22,-1.73 and β = -4.23 pmol/L; 95% CI: 6.17,-2.28), respectively, in men, and increased levels of SHBG (β = 7.25 nmol/L; 95% CI:2.02,12.8 and β = 9.42 nmol/L; 95% CI:4.08,15.0), respectively, in women. p,p'-DDT and β-HCCH, and o,p'-DDT were also associated with decreased testosterone (T) and bioavailable T (ng/dL) levels in men. Adiposity modified associations in men, revealing stronger inverse associations of PCBs, PBDEs, and several OCPs with LH, SHBG, E2, bioavailable E2, T, and the ratios of LH to FSH and E2 to T in those with below median body mass index and waist-to-hip ratio.

CONCLUSION

Distinct patterns of hormone dysregulation with increasing POPs serum concentration were identified in men and post-menopausal women. In men but less so in postmenopausal women, adiposity modified associations of POPs serum concentration with sex-related hormones.

The Impact of Pregestational Diabetes on Maternal Morbidity and Mortality: Trends, Challenges, and Future Directions

Maternal mortality in the United States is on the rise, demonstrating a concerning trend that stands in stark contrast to the falling rates in other developed countries. A key challenge facing the improvement of maternal care is the mounting prevalence of chronic health conditions such as hypertension and diabetes, which are often linked to poor diet and sedentary lifestyle. Pregestational diabetes now impacts 1 to 2% of pregnancies, while gestational diabetes affects another 7.8%. Both type 1 and type 2 diabetes elevate the risk of severe maternal morbidity and mortality (SMM), including severe cardiac morbidity, hypertensive disorders of pregnancy, hemorrhage, infection, and mental health conditions. The increase in diabetes is thought to account for 17% of the increase in maternal mortality between 1997 and 2012. Another critical issue facing maternal care is the significant disparity in pregnancy outcomes among populations facing greater burdens of adverse social determinants of health, including socioeconomic characteristics, chronic stress, and systemic racism. For example, non-Hispanic Black women are 2.5 times more likely to die during pregnancy and the postpartum period than non-Hispanic White women. Vulnerable populations, often minorities, are also more likely to develop risk factors for SMM, such as type 2 diabetes. As pregestational diabetes is a particularly morbid condition in pregnancy, examining its complications and evidence-based treatments could significantly impact both maternal mortality rates and disparities in pregnancy outcomes in the United States. This review explores the relationship between pregestational diabetes and SMM, how the risk of SMM can be modified by disparities, and avenues for advancing care through future research. KEY POINTS: · Diabetes during pregnancy greatly increases the risk of SMM.. · Comprehensive care can improve outcomes in high-risk pregnancies with diabetes.. · Adverse social determinants of health worsen outcomes in pregnancies affected by diabetes.. · Improving diabetes care in pregnancy offers an opportunity to enhance maternal outcomes..

Impact of Medically Tailored Meals on Clinical Outcomes Among Low-Income Adults with Type 2 Diabetes: A Pilot Randomized Trial

BACKGROUND

Adults with type 2 diabetes (T2DM) and adverse social determinants of health experience barriers to healthful eating, and achieve poorer glycemic control and clinical outcomes.

OBJECTIVE

To examine the impact of medically tailored meals (MTM) with medical nutrition therapy (MNT) on clinical outcomes among adults with DM.

DESIGN

Pilot randomized controlled trial.

PARTICIPANTS

English-speaking adults with DM and hemoglobin A1c (A1c) levels > 8% insured by Maryland Medicaid plans.

INTERVENTION

The treatment group received home delivery of 12 medically tailored, frozen meals and a fresh produce bag weekly for 3 months, and individual calls with a registered dietitian monthly for 6 months in addition to usual care. The control group received usual care. Outcomes were change from baseline to 6 months in A1c (primary), body mass index (BMI), blood pressure, food insecurity, and diabetes-related quality of life, knowledge, and self-efficacy (secondary).

KEY RESULTS

We randomized 74 adults; 77% completed data collection. The mean age was 48 years, 40% were male, 77% were Black, and the mean A1c was 10.3%. Eighty-six percent of meals were delivered, and on average 4.8 nutrition visits were completed. At 6 months, both groups had similar improvements in A1c (- 0.7 vs. - 0.6%); the control group reported more favorable changes in diabetes medications. Changes in systolic blood pressure and BMI at 6 months did not differ between groups. Diabetes-related quality of life, knowledge, and self-efficacy improved modestly, but not differently by group. Food insecurity decreased significantly from baseline to 3 months in the intervention (53 to 17%) compared to control (48 to 44%; p < 0.05), which lessened but remained significant at 6 months.

CONCLUSIONS

Recruitment and retention of an at-risk group of adults with DM was feasible. Intervention uptake was good but did not improve clinical outcomes. More comprehensive and clinically integrated interventions are likely needed to achieve significant clinical benefits.

Personalized and Culturally Tailored Features of Mobile Apps for Gestational Diabetes Mellitus and Their Impact on Patient Self-Management: Scoping Review

Background

Gestational diabetes mellitus (GDM) is an increasingly common high-risk pregnancy condition requiring intensive daily self-management, placing the burden of care directly on the patient. Understanding personal and cultural differences among patients is critical for delivering optimal support for GDM self-management, particularly in high-risk populations. Although mobile apps for GDM self-management are being used, limited research has been done on the personalized and culturally tailored features of these apps and their impact on patient self-management.

Objective

This scoping review aims to explore the extent to which published studies report the integration and effectiveness of personalized and culturally tailored features in GDM mobile apps for patient self-management support.

Methods

We examined English-language peer-reviewed articles published between October 2016 and May 2023 from PubMed, CINAHL, PsycINFO, ClinicalTrials.gov, Proquest Research Library, and Google Scholar using search terms related to digital tools, diabetes, pregnancy, and cultural tailoring. We reviewed eligible articles and extracted data using the Arskey and O'Malley methodological framework.

Results

Our search yielded a total of 1772 articles after the removal of duplicates and 158 articles for full-text review. A total of 21 articles that researched 15 GDM mobile apps were selected for data extraction. Our results demonstrated the stark contrast between the number of GDM mobile apps with personalized features for the individual user (all 15 mobile apps) and those culturally tailored for a specific population (only 3 of the 15 mobile apps). Our findings showed that GDM mobile apps with personalized and culturally tailored features were perceived to be useful to patients and had the potential to improve patients' adherence to glycemic control and nutrition plans.

Conclusions

There is a strong need for increased research and development to foster the implementation of personalized and culturally tailored features in GDM mobile apps for self-management that cater to patients from diverse backgrounds and ethnicities. Personalized and culturally tailored features have the potential to serve the unique needs of patients more efficiently and effectively than generic features alone; however, the impacts of such features still need to be adequately studied. Recommendations for future research include examining the cultural needs of different ethnicities within the increasingly diverse US population in the context of GDM self-management, conducting participatory-based research with these groups, and designing human-centered mobile health solutions for both patients and providers.

Out-of-Pocket Costs Burden in Marketplace Plans for People With Diabetes

Background

The Affordable Care Act (ACA) aims to expand coverage and increase access to health insurance. Despite the increase of insured individuals, there are a number of concerns about whether coverage and care are affordable. Prior studies document a growing concern with rising premiums and cost-sharing, including deductibles, particularly for those with chronic conditions.

Objective

Compare the ACA marketplace plan availability and costs across 17 states for individuals with varying diabetic engagement profiles and their related medical needs.

Design

Descriptive Cost Analysis.

Methods

Using Healthcare.gov individual state marketplace websites, we utilized a descriptive cost analysis to compare plan availability and costs for premiums, deductibles, co-payments, and co-insurance for an individual aged 63 years old, who was either a non-diabetic, high-engagement or low-engagement diabetic in urban and rural areas. Using the second lowest monthly premium silver plan (the benchmark plan), we calculated annual costs for premiums, co-insurance, co-payments, and deductibles for these individual profiles. We assessed statistical differences between health care component costs, within and across urban and rural areas, using t-tests.

Results

The findings highlight within and across states, individuals with diabetes, particularly low-engagement diabetics, spend a significantly higher percent of their income on additional health care costs, above their premium, than non-diabetic individuals. In some states, low-engagement diabetic patients spend upwards of 3 times more than high-engagement diabetic patients, highlighting an additional cost burden. For low-engagement diabetics, deductibles are driving health care spending with an average of 59% of health care spending coming from deductible payments. Results do not show statistically different costs across urban and rural diabetic patients.

Conclusion

Despite the ACA's success, results highlight variation in plan availability across states and disproportionate cost burden placed on moderate income individuals, especially related to deductible, and co-payments for those with chronic diseases.

Health and Racial Disparities: Importance of Accurate and Reliable Ethnicity, Race, and Language Data

Introduction: Accurate demographic data are essential to identify and monitor differences, trends, and changes in diabetes-related conditions between Hispanics and non-Hispanic Blacks (NHBs). It also provides pertinent information to reduce health and racial disparities among English- and Spanish-speakers. Method: The study's design was a quantitative cross-sectional one. Electronic medical record (EMR) and survey data of the same sample were compared. Descriptive statistics were computed for ethnicity, preferred language, and physiological data. Frequency and percentages were calculated for each continuous and categorical variable. Chi-square was calculated to compare physiological variables by ethnicity and language. Results: During a 5-month period (September 2021-February 2022), 106 individuals from New York City with diabetes took part in this study. Among Hispanics, most from the EMR identified as Other (82.4%), whereas from the survey, most identified as White (57.1%). More Hispanics (19%) and Spanish speakers (18%) had high triglyceride levels compared to NHBs (2%) and English speakers (3%). Conclusion: Ensuring that demographic data are accurate can better inform programs. Because Hispanics and Spanish speakers had the highest triglyceride levels, diabetes programs need to include information on cardiovascular disease and must be available in Spanish, to further reduce risk factors, improve health outcomes, and promote health equity among these populations.

Differences in the treatment patterns of small renal masses: A disaggregated analyses by race/ethnicity

OBJECTIVE

To characterize differences in the management of small renal masses among disaggregated race/ethnic subgroups.

MATERIAL AND METHODS

We used the National Cancer Database to identify patients diagnosed with clinically localized kidney cancer and tumor size ≤4cm. We studied 16 predefined racial/ethnic subgroups and compared 1) the use of surveillance for tumors <2cm and 2) the use of radical nephrectomy for tumors ≤4cm. We used multivariable logistic regression to evaluate the independent association of race/ethnicity with management, adjusting for baseline characteristics. We also compared our disaggregated analyses to the 6 National Institute of Health aggregate race categories.

RESULTS

We identified 286,063 patients that met inclusion criteria. For tumors <2cm, Black Non-Hispanic (aOR 1.43) and Mexican patients (aOR 1.29) were significantly more likely to undergo surveillance compared to White patients. For tumors ≤4cm, Black Non-Hispanic (aOR 1.43), Filipino (aOR 1.28), Japanese (aOR 1.28), Mexican (aOR 1.32), and Native Indian patients (aOR 1.15) were significantly more likely to undergo radical nephrectomy compared to White patients. When comparing our disaggregated analyses to the NIH categories, we found that many disaggregated race/ethnic subgroups had associations with management strategies that were not represented by their aggregated group.

CONCLUSIONS

In this study, we found that the use of surveillance for tumors <2cm and radical nephrectomy for tumors ≤4cm varied significantly among certain race/ethnic subgroups. Our disaggregated approach provides information on differences in treatment patterns in particular subgroups that warrant further study to optimize kidney cancer care for all patients.

Comparing diabetes prediction based on metabolic dysfunction-associated steatotic liver disease and nonalcoholic fatty liver disease: the ELSA-Brasil study

We aimed to compare nonalcoholic fatty liver disease (NAFLD) and metabolic dysfunction-associated steatotic liver disease (MASLD) definitions concerning diabetes prediction in a large sample of Brazilian adults. As a secondary objective, we compared associations between NAFLD/MASLD and diabetes across self-declared race/skin color groups. The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) is a prospective cohort study of Brazilian civil servants (35-74 years) enrolled from 2008 to 2010 and followed up from 2012-2014 and 2017-2019. We ascertained type 2 diabetes mellitus at baseline as well as follow-up visits based on self-reported diagnosis, medication use, and glycemic tests (fasting and 2h post-OGTT glucose and HbA1c). We excluded individuals with heavy alcohol consumption or self-reported cirrhosis/hepatitis. We analyzed 7,073 subjects. NAFLD was defined by ultrasound-based steatosis. Participants with steatosis and at least one cardiometabolic factor were considered as having MASLD. Cox proportional hazards models were performed to evaluate the association between NAFLD/MASLD and the incidence of type 2 diabetes mellitus. At baseline, 33.9% of individuals presented NAFLD and 32.5% presented MASLD. Over 9.4 years of follow-up, the relative increase in the incidence of diabetes was 78% for NAFLD (HR = 1.78; 95%CI: 1.58-2.01) and 88% for MASLD (HR = 1.88; 95%CI: 1.67-2.12). Associations did not differ significantly among race/skin color groups (p for interaction = 0.10 for MASLD and 0.08 for NAFLD). In this large cohort of middle-aged and older Brazilian adults, the relative incidence of diabetes was similar for NAFLD and MASLD definitions, with similar associations in all ethnic groups.

Comparative analysis of White and African American groups reveals unique lipid and inflammatory features of diabetes

Importance

African Americans have a higher prevalence of Type 2 Diabetes (T2D) compared to White groups. T2D is a health disparity clinically characterized by dysregulation of lipids and chronic inflammation. However, how the relationships among biological and sociological predictors of T2D drive this disparity remains to be addressed.

Objective

To determine characteristic plasma lipids and systemic inflammatory biomarkers contributing to diabetes presentation between White and African American groups.

Design

We performed a cross-sectional retrospective cohort study using pre-existing demographic and clinical data from two diverse studies: Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) and AllofUs. From HANDLS (N=40), we used information from wave 1 (2004). From AllofUs (N=17,339), we used data from the Registered Tier Dataset v7, available in the AllofUs researcher workbench.

Setting

HANDLS is a population-based cohort study involving 3720 participants in the Baltimore area supported by the Intramural Research Program of the National Institute on Aging. HANDLS is a longitudinal study designed to understand the sources of persistent health disparities in overall longevity and chronic disease in White and African American individuals. The AllofUs study is an NIH funded multicenter study consisting of patient-level data from 331,382 individuals from 35 hospitals in the United States aimed at sampling one million or more people living in the United States to provide a collection of broadly accessible data.

Participants

The HANDLS subcohort participants (N=40) were divided into four groups equally distributed by race, sex, and diabetes status. Groups were also matched by age, body mass index, and poverty status. The analysis pipeline consisted of evaluating the significance of the variables race and disease status using the 2-way ANOVA test and post-ANOVA comparisons using Fisher LSD test, reporting unadjusted p-values. Additionally, unsupervised (PCA) and supervised (OPLS-DA) clustering analysis was performed to determine putative biological drivers of variability and main immunological and metabolic features characterizing diabetes in White and African American groups from HANDLS. Major clinical findings were validated in a large cohort of White and African American groups with T2D in the AllofUS research study (N=17,339). AllofUs groups were of similar range in age and BMI as HANDLS. Furthermore, a linear regression model was built adjusting for age and BMI to determine differences in clinical findings between White and African American groups with T2D.

Main Outcomes and Measures

Primary outcomes using a HANDLS subcohort (N=40) were clinical parameters related to diabetes, plasma lipids determined by lipidomics and measured by mass spectrometry, and cytokine profiling using a customized panel of 52 cytokines and growth factors measured by Luminex. Outcomes evaluated in the AllofUs study (N=17,339) were clinical: cholesterol to HDL ratio, triglycerides, fasting glucose, insulin, and hemoglobin A1C.

Results

In the HANDLS subcohort, White individuals with diabetes had elevated cholesterol to HDL ratio (mean difference -1.869, p =0.0053 ) , high-sensitivity C-reactive protein (mean difference -9.135, p =0.0040), and clusters of systemic triglycerides measured by lipidomics, compared to White individuals without diabetes. These clinical markers of dyslipidemia (cholesterol to HDL ratio and triglycerides) and inflammation (hs-CRP) were not significantly elevated in diabetes in African Americans from the HANDLS subcohort. These results persisted even when controlling for statin use. Diabetes in White individuals in the HANDLS cohort was characterized by a marked elevation in plasma lipids, while an inflammatory status characterized by Th17-cytokines was predominant in the African American group from the HANDLS subcohort. We validated the key findings of elevated triglycerides and cholesterol to HDL ratio in White individuals with T2D in a sample (N=17,339) of the AllofUs study.

Conclusions and Relevance

Our results show that diabetes can manifest with healthy lipid profiles, particularly in these cohorts of African Americans. This study suggests that Th17-inflammation associated with diabetes is characteristic of African Americans, while a more classic inflammation is distinctive of White individuals from HANDLS cohort. Further, clinical markers of dyslipidemia seem to characterize diabetes presentation only in White groups, and not in African Americans.

Type 2 diabetes complications in ethnic minority compared with European host populations: a systematic review and meta-analysis

This systematic review and meta-analysis aimed to quantify differences in type 2 diabetes (T2D) complications between ethnic minority populations and European host populations, in both cross-sectional and prospective studies. Following Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines, we searched multiple databases for studies (until July 1, 2024) with T2D complications as outcome. Studies were included if they compared ethnic minority populations to the host population and were conducted in Europe. T2D complications included mortality, macrovascular and microvascular complications and mental disorders. Risk of bias was assessed with the assessment tool for observational cohort and cross-sectional studies. Risk estimates were pooled using random effects models. From a total of 2901 references, 58 studies were included, comprising 805 to 1 230 410 individuals for the meta-analyzed complications. Compared with the host population, ethnic minority populations generally had a lower risk of all-cause mortality (RR 0.70 (95% CI 0.63; 0.77); I2=87%)) and macrovascular complications (RR 0.72 (95% CI 0.58; 0.88); I2=88%). South Asians, however, showed comparable risks for most macrovascular complications and a slighthly higher risk of major adverse cardiovascular events. Increased risks for microvascular complications, nephropathy and retinopathy were observed (eg, in prospective studies RR 1.50 (95% CI 1.14; 1.96); I2=86% for nephropathy). No ethnic differences were observed for mental disorders. Ethnic minority populations with T2D in Europe are generally at reduced risk of all-cause mortality and macrovascular complications, but at higher risk of nephropathy and retinopathy. Our findings may help to further identify high-risk populations and to develop guidelines and future interventions. PROSPERO registration number:PROSPERO 2022 CRD42022366854.

Disparities in Use of Novel Diabetes Medications by Insurance: A Nationally Representative Cohort Study

BACKGROUND

Minority racial and ethnic populations have the highest prevalence of type 2 diabetes mellitus but lower use of sodium-glucose co-transporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP1ra), novel medications that reduce morbidity and mortality. Observed disparities may be due to differences in insurance coverage, which have variable cost-sharing, prior authorization, and formulary restrictions that influence medication access.

OBJECTIVE

To assess whether racial/ethnic differences in SGLT2i and GLP1ra use differ by payer.

DESIGN

Cross-sectional analysis of 2018 and 2019 Medical Expenditure Panel Survey data.

PARTICIPANTS

Adults ≥ 18 years old with diabetes.

MAIN MEASURES

We defined insurance as private, Medicare, or Medicaid using ≥ 7 months of coverage in the calendar year. We defined race/ethnicity as White (non-Hispanic) vs non-White (including Hispanic). The primary outcome was use of ≥ 1 SGLT2i or GLP1ra medication. We used multivariable logistic regression to assess the interaction between payer and race/ethnicity adjusted for cardiovascular, socioeconomic, and healthcare access factors.

KEY RESULTS

We included 4997 adults, representing 24.8 million US adults annually with diabetes (mean age 63.6 years, 48.8% female, 38.8% non-White; 33.5% private insurance, 56.8% Medicare, 9.8% Medicaid). In our fully adjusted model, White individuals with private insurance had significantly more medication use versus non-White individuals (16.1% vs 8.3%, p < 0.001), which was similar for Medicare beneficiaries but more attenuated (14.7% vs 11.0%, p = 0.04). Medication rates were similar among Medicaid beneficiaries (10.0% vs 9.0%, p = 0.74).

CONCLUSIONS

Racial/ethnic disparities in novel diabetes medications were the largest among those with private insurance. There was no disparity among Medicaid enrollees, but overall prescription rates were the lowest. Given that disparities vary considerably by payer, differences in insurance coverage may account for the observed disparities in SGLT2i and GLP1ra use. Future studies are needed to assess racial/ethnic differences in novel diabetes use by insurance formulary restrictions and out-of-pocket cost-sharing.

Racial disparities in trend, clinical characteristics and outcomes in Takotsubo syndrome

INTRODUCTION

Takotsubo syndrome (TTS) is an acute transient nonischemic cardiomyopathy often characterized by its hallmark feature of left ventricular apical ballooning. The correlation between racial backgrounds and the prognosis of individuals with TTS remains poorly defined. Our study aimed to explore the influence of race on the trends, clinical presentations, and outcomes in patients diagnosed with TTS.

METHODS

We queried the National Inpatient Sample (NIS) database from 2016 to 2020 and identified hospitalizations with TTS. We compared the clinical features and outcomes across three different races - non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic population. The primary outcome was in-hospital mortality.

RESULTS

76,505 weighted hospitalizations for TTS were identified, of which 65,495 (85.6%) were non-Hispanic White, 5,830 (7.6%) were non-Hispanic Black, and 5,180 (6.8%) were Hispanics. After propensity-score matching, NHB patients had higher odds of acute kidney injury (OR: 1.49, 95% CI: 1.21-1.84, p < 0.001) and mechanical ventilation (OR: 1.33, 95% CI: 1.04-1.68, p = 0.02). Hispanic patients had a higher incidence of acute kidney injury requiring dialysis when compared to NHW patients (OR: 2.53, 95% CI: 1.11-5.77, p = 0.027). There was no significant difference in terms of in-hospital mortality between NHB and Hispanic patients when compared to NHW patients. Notably, Hispanic populations experienced a higher mortality rate during the COVID-19 period.

CONCLUSION

Our study suggested significant differences in the outcomes of TTS across different racial groups. Hispanic populations experienced a higher mortality rate with TTS during the COVID-19 era. Further research should emphasize discovering the factors contributing to the observed disparities.

Impact of continuous glucose monitoring on emergency department visits and all-cause hospitalization rates among Medicaid beneficiaries with type 2 diabetes treated with multiple daily insulin or basal insulin therapy

BACKGROUND

The increasing prevalence of diabetes in the United States continues to drive a steady rise in health care resource utilization, especially emergency department visits and all-cause hospitalizations, and the associated costs.

OBJECTIVE

To investigate the impact of continuous glucose monitoring (CGM) on emergency department visits and all-cause hospitalizations among Medicaid beneficiaries with type 2 diabetes (T2D) treated with multiple daily insulin injections (MDIs) or basal insulin therapy (BIT) in a real-world setting.

METHODS

In this retrospective, 12-month analysis, we used the Inovalon Insights claims dataset to evaluate the effects of CGM acquisition on emergency department visits and all-cause hospitalizations in the Managed Medicaid population. The analysis included 44,941 beneficiaries with T2D who were treated with MDIs (n = 35,367) or BIT (n = 9,574). Primary outcomes were changes in the number of emergency department visits and all-cause hospitalizations following 6 months after acquisition of CGM (post-index period) compared with 6 month prior to CGM acquisition (pre-index period). The first claim for CGM was the index date. Inclusion criteria were as follows: aged younger than 65 years, diagnosis of T2D, claims for short- or rapid-acting insulin (MDI group) or basal insulin (not rapid-acting) (BIT group), acquisition of a CGM device between January 1, 2017, and September 30, 2022, and continuous enrollment in their health plan throughout the pre-index and post-index periods.

RESULTS

In the MDI group, all-cause inpatient hospitalization rates decreased from 3.25 to 2.29 events/patient-year (hazard ratio = 0.12; 95% CI = 0.11-0.13; P < 0.001) and emergency department visit rates decreased from 2.15 to 1.86 events/patient-year (hazard ratio = 0.52; 95% CI = 0.50-0.53; P < 0.001). In the BIT group, all-cause inpatient hospitalization rates decreased from 1.63 to 1.39 events/patient-year (hazard ratio = 0.11; 95% CI = 0.09-0.12; P < 0.001) and emergency department visit rates decreased from 1.60 to 1.43 events/patient-year (hazard ratio = 0.47; 95% CI = 0.44-0.50; P < 0.001).

CONCLUSIONS

Acquisition of CGM is associated with significant reductions in emergency department visits and all-cause hospitalizations among people with T2D treated with MDIs or BIT.

Charcot neuroarthropathy in diabetic patients in Texas

AIMS

Charcot neuroarthropathy (CN) is a complex disease of the bone and joints that can lead to serious and life-threatening complications. This study investigates epidemiologic trends in diabetic CN in Texas and the impact of age on these values.

METHODS

A retrospective analysis was conducted using the Texas Department of State Health Services Hospital Discharge Data Public Use Data File. Using International Classification of Diseases, Ninth (ICD-9) and Tenth (ICD-10) Revision codes, we identified patients with diabetes and Charcot ankle or foot. Data extracted included diagnoses, race, and gender. Population rates were estimated using census data, calculated per 1000 population and standardized by age.

RESULTS

Overall and age-standardized rates of CN increased each year from 2006 to 2016, except for a downward trend from 2014 to 2016. Poisson regression revealed significant increases in the incidence rate ratio compared to 2006 for each year from 2008 to 2016. When age group is included, all years except 2007 show a significant increase relative to 2006, and all age groups have increased rates relative to ages 18-44. Major and minor amputations in patients with CN have increased.

CONCLUSIONS

The increasing rates of CN and amputations highlight the need for further research and standardized strategies for diagnosis and management.

Systematic review of disparities in continuous glucose monitoring and insulin pump utilization in the United States: Key themes and evidentiary gaps

AIM

This study aims to provide a comprehensive overview of real-world evidence pertaining to disparities in the utilization of continuous glucose monitors (CGMs)/insulin pumps to highlight potential evidentiary gaps and discern emerging themes from the literature.

MATERIALS AND METHODS

A systematic review of published manuscripts and abstracts was conducted from: MEDLINE, EMBASE, Nursing and Allied Health, Web of Science and CINHAL. Attributes related to patients, outcomes, interventions (CGMs/pumps/both) and study type were captured. In addition, factors associated with disparities in device utilization were examined.

RESULTS

Thirty-six studies were included in the final analysis; the studies predominantly focused on people living with type 1 diabetes. Only two studies included individuals with type 2 diabetes. Almost two-thirds of the studies reported outcomes associated with disparities (e.g. glycated haemoglobin, diabetic ketoacidosis, resource utilization). Most studies highlighted disparities across race, ethnicity and insurance type. Evidentiary gaps were identified, particularly in the evidence for people with type 2 diabetes, the continuation of CGM/pump use and limited studies addressing disparities among Native Americans/American Indians.

CONCLUSION

This study reveals critical disparities in diabetes technology use across race, ethnicity and insurance type, particularly among people with type 1 diabetes. Evidentiary gaps assessing disparities in diabetes technology use persist, particularly concerning people with type 2 diabetes, Native American/American Indian and LGBTQ+ populations, and in outcomes related to continuation of use. Social and digital determinants of health, such as income, transportation, residential location and technological literacy, are crucial to achieving equitable access. Future research should focus on the patient journey to identify opportunities for equitable access to diabetes technology as its use grows.

Chronic Work Discrimination, Allostatic Load, and HbA1c in Older Workers

BACKGROUND AND OBJECTIVE

Work discrimination is an important public health problem with consequences for health. This study examined the effect of chronic work discrimination on 4-year changes in HbA1c, as a reflection of glucose control and type 2 diabetes risk in older workers and assessed whether allostatic load (AL) affected the strength of this association.

RESEARCH DESIGN AND METHODS

We used Health and Retirement Study data (2010-2016, n = 3,246). Conditional change multinomial logistic regression examined the association between chronic work discrimination, high AL (4 or more out of 8 high-risk biomarkers), and HbA1c, while accounting for relevant covariates.

RESULTS

Black participants had the highest rates of baseline (22.7%) and follow-up (28%) HbA1c levels, AL (38%), and chronic work discrimination (39%; p < .01). Severe chronic work discrimination was associated with elevated HbA1c (relative risk ratio [RRR] = 1.61, 95% confidence interval [CI] = 1.07, 2.43). AL was associated with elevated HbA1c (RRR = 1.49, 95% CI = 1.04, 2.14). Relative to White participants, Hispanic (RRR = 1.52, 95% CI = 1.07, 2.16, RRR = 1.81, 95% CI = 1.051, 3.12), and Black (RRR = 2.42, 95% CI = 1.82, 3.23; RRR = 3.00, 95% CI = 1.97, 4.56) participants had an increased risk of intermediate and elevated HbA1c, respectively. Among those with long job tenure (≥5 years), both moderate (RRR = 1.81, 95% CI = 1.11, 2.96) and severe (RRR = 1.90, 95% CI = 1.15, 3.12) chronic work discrimination was associated with elevated HbA1c.

DISCUSSION AND IMPLICATIONS

Chronic work discrimination was associated with HbA1c; however, no moderating effects of AL were observed. Findings underscore a need for organizational and public health measures to establish strong anti-discrimination laws in the workplace to improve the work environment of older workers and reduce diabetes risk.

Racial and Ethnic Differences in Diabetes Care Quality in A National Sample of Cancer Survivors Relative to Non-Cancer Controls

BACKGROUND

Among cancer survivors, diabetes is associated with greater morbidity and mortality. The objective of this study is to describe racial/ethnic disparities in diabetes care quality (DCQ) among cancer survivors compared to non-cancer controls.

METHODS

We used Medical Expenditure Panel Survey Household Component data (2010-2018). Black, non-Hispanic White (NHW), and Hispanic respondents diagnosed with diabetes and cancer were frequency matched 1:5 to non-cancer controls. Multivariable logistic regression estimated associations for specific indices and overall DCQ by race/ethnicity stratified by cancer site/status in partially adjusted (not controlling for socioeconomic indicators) and fully adjusted models.

RESULTS

The final sample of 4775 included cancer survivors (n = 907 all cancers; n = 401 breast; n = 167 colon; n = 339 prostate) and non-cancer controls (n = 3868) matched by age, race/ethnicity, and year. In partially adjusted models, Black (adjusted odds ratio, AOR) 0.67 [95% CI 0.54-0.83]) and Hispanic (AOR 0.68 [95% CI 0.54-0.87]) non-cancer controls had significant disparities for overall DCQ compared to NHWs. Among cancer survivors, DCQ disparities for Black (AOR 0.62, [95% CI 0.4-0.96]) and Hispanics (AOR 0.60, [95% CI 0.38-0.97]) were identified. Among prostate cancer survivors, DCQ disparities were identified for Blacks (AOR 0.38; [95% CI 0.20-0.72]) and Hispanics (AOR 0.39; [95% CI 0.17-0.89]) compared to NHWs. Racial disparities among Black controls and Black prostate cancer survivors remained significant in fully adjusted models.

CONCLUSION

Diabetes care disparities are evident among cancer survivors and salient among non-cancer controls. Strategies to promote health equity should target specific care indices among survivors and emphasize equitable DCQ strategies among Black and Hispanic communities.

Follow-up in a point-of-care diabetic retinopathy program in Pittsburgh: a non-concurrent retrospective cohort study

BACKGROUND

The Point-of-Care Diabetic Retinopathy Examination Program (POCDREP) was initiated in 2015 at the University of Pittsburgh/UPMC in response to low diabetic retinopathy (DR) examination rates, a condition affecting a quarter of people with diabetes mellitus (PwDM) and leading to blindness. Early detection and treatment are critical with DR prevalence projected to triple by 2050. Approximately, half of PwDM in the U.S. undergo yearly examinations, and there are reported varying follow-up rates with eye care professionals, with limited data on the factors influencing these trends. POCDREP aimed to address screening and follow-up gap, partnering with diverse healthcare entities, including primary care sites, free clinics, and federally qualified health centers.

METHODS

A non-concurrent retrospective cohort study spanning 2015-2018 examined data using electronic health records of patients who underwent retinal imaging. Imaging was performed using 31 cameras across various settings, with results interpreted by ophthalmologists. Follow-up recommendations were made for cases with vision-threatening DR (VTDR), incidental findings, or indeterminate results. Factors influencing follow-up were analyzed, including demographic, clinical, and imaging-related variables. We assessed the findings at follow-up of patients with indeterminate results.

RESULTS

Out of 7,733 examinations (6,242 patients), 32.25% were recommended for follow-up. Among these, 5.57% were classified as having VTDR, 14.34% had other ocular findings such as suspected glaucoma and age-related macular degeneration (AMD), and 12.13% were indeterminate. Of those recommended for follow-up, only 30.87% were assessed by eye care within six months. Older age, marriage, and severe DR were associated with higher odds of following up. Almost two thirds (64.35%) of the patients with indeterminate exams were found with a vision-threatening disease at follow-up.

CONCLUSION

The six-month follow-up rate was found to be suboptimal. Influential factors for follow-up included age, marital status, and the severity of diabetic retinopathy (DR). While the program successfully identified a range of ocular conditions, screening initiatives must extend beyond mere disease detection. Ensuring patient follow-up is crucial to DR preventing programs mission. Recommended strategies to improve follow-up adherence include education, incentives, and personalized interventions. Additional research is necessary to pinpoint modifiable factors that impact adherence and to develop targeted interventions.

Patients' and Providers' Perspectives of the Transition of Care from Hospital to Community for Hispanic/Latino Adults with Diabetes

INTRODUCTION

Transition of care is a critical point of care for Hispanic/Latino patients with diabetes, who face higher rates of diabetes-related complications and hospital readmission and challenges during the transition of care from hospital to the community.

METHODS

Using semi-structured interviews, with questions tailored to each group, we explored patients' and providers' perspectives of their experiences and challenges during the transition of care of Hispanic/Latino adult patients with diabetes from the hospital to the community.

RESULTS

Overlapping themes emerged from both patient and provider interviews identifying common barriers regarding the transition of care, including discordance due to language/communication barriers, perceived burden/nuisance, lack/unawareness of available resources, and lack of patient education.

CONCLUSIONS

Findings in this study provide a frame of reference that can be used to address challenges facing Hispanic/Latino patients with diabetes. The uniqueness of this study is its exploration of the perspectives of patients and healthcare providers and the overlapping themes that emerged. Additionally, timely outpatient follow-up care, education, and reducing communication discordance can help with lowering readmission rates for patients with diabetes, especially those who are medically disadvantaged and have language barriers.

The Chronic Conditions Care Collaborative (4C Collaborative): A Platform for Improving Diabetes and Heart Disease Outcomes in Rural South Carolina

Rural U.S. counties experience racial, geographic, and socioeconomic disparities in chronic diseases. Collaborations among stakeholders in rural areas are needed to make measurable changes in health care outcomes in South Carolina. The Chronic Conditions Care Collaborative (4C Collaborative) was developed to provide an opportunity for health care teams in medically underserved areas of South Carolina to convene to improve diabetes and heart disease outcomes. The 4C Collaborative was a quality improvement (QI) learning collaborative focused on the identification of patients with undiagnosed hypertension, team-based care through medication therapy management (MTM), and diabetes management. All QI work was approached through a health equity lens. Fifteen medical practices across two cohorts participated in the 4C Collaborative and gained access to more than 35 hours of educational content and guided action steps to create systemic changes specific to the needs of their patient population. Participation also conferred access to one-on-one technical assistance with faculty subject-matter experts. The activities within the 4C Collaborative allowed health care practices to identify areas of improvement within their practices and test improvement strategies through Plan-Do-Study-Act (PDSA) cycles. Best practices and lessons learned from learning collaborative participants were compiled into storyboards and presented during end of program celebrations.

Multi-year population-based analysis of Asian patients with acute decompensated heart failure and advanced chronic kidney disease

BACKGROUND

Data on disparities in outcomes and risk factors in Asian patients with advanced chronic kidney disease admitted for heart failure are scare.

METHODS

This was a retrospective cohort study that utilized data from the National Inpatient Sample between January 2016 and December 2019. Patients who had a primary diagnosis of acute decompensated heart failure and a concomitant diagnosis of advanced CKD were included. The primary outcome of interest was in-hospital mortality. Secondary outcomes include hospital cost, length of stay, and other clinical outcomes. Weighted multivariable logistic regression was used to adjust for comorbidities.

RESULTS

There were 251,578 cases of ADHF with advanced CKD, out of which 2.6 % were from individuals of Asian ethnicity. Asian patients exhibited a higher burden of comorbidities in comparison to other UREM patients, but a lower burden than White patients. Regardless of differences in comorbidity burden, Asian patients exhibited a higher likelihood of experiencing severe consequences. After adjusting for comorbidies, White (OR:1.11; 95 % CI 1.03-1.20;0.009) patients had higher odds of mortality than Asian patients. However, Blacks (OR: 0.58; 95 % CI 0.53 to 0.63; p < 0.001) and Hispanics (OR: 0.69; 95 % CI 0.62 to 0.78; p < 0.001) had lower odds of mortality.

CONCLUSION

This first population-based studies shows that Asian patients with advanced CKD admitted for ADHF have greater comorbidity burden and poorer outcomes Black and Hispanic patients. This data underscores the importance of comprehensive approaches in phenotyping, and ethnic specific interventions.

Racial, ethnic and regional differences in the effect of sodium-glucose co-transporter 2 inhibitors and glucagon-like peptide 1 receptor agonists on cardiovascular and renal outcomes: a systematic review and meta-analysis of cardiovascular outcome trials

OBJECTIVES

The cardiorenal protective effects of sodium-glucose co-transporter 2 inhibitors (SGLT2-Is) and glucagon-like peptide 1 receptor agonists (GLP1-RAs) across racial and ethnic groups are not well defined. By conducting a systematic review and meta-analysis of all randomised, placebo-controlled, cardiovascular disease (CVD) outcomes trials (CVOTs), we aimed to compare racial/ethnic as well as regional patterns in the effects of SGLT2-Is and GLP1-RAs on cardiovascular and renal outcomes in patients with type 2 diabetes (T2D).

DESIGN

Trials were identified from MEDLINE, Embase, the Cochrane Library, and search of bibliographies to 7 July 2023. Setting North America, South/Central America, Europe (Eastern and Western), Asia, Australia-New Zealand (Pacific), Asia/Pacific, and Africa.

SETTING

North America, South/Central America, Europe (Eastern and Western), Asia, Australia-New Zealand (Pacific), Asia/Pacific, and Africa.

PARTICIPANTS

people with type 2 diabetes enrolled in cardiovascular outcome trials of SGLT2-Is and GLP1-RAs.

MAIN OUTCOME MEASURES

Outcomes were (i) major adverse cardiovascular events (MACE), (ii) composite CVD death/heart failure (HF) hospitalization; (iii) composite renal outcome; and (iv) their components. Study-specific hazard ratios (HRs) with 95% confidence intervals (CIs) were pooled.

RESULTS

In total, 14 unique CVOTs (7 comparing SGLT2-Is vs placebo and 7 comparing GLP1-RAs vs placebo) were eligible. The proportion of participants enrolled in the trials ranged from 66.6-93.2% for White populations, 1.2-21.6% for Asian populations, 2.4-8.3% for Black populations and 0.9-23.1% for Other populations. The HR (95% CI) for MACE comparing SGLT2-Is vs placebo was 0.92 (0.86-0.98), 0.69 (0.53-0.92) and 0.70 (0.54-0.91) for White, Asian and Hispanic/Latino populations, respectively. Comparing GLP1-RAs vs placebo, the corresponding HR (95% CI) was 0.88 (0.80-0.97), 0.76 (0.63-0.93) and 0.82 (0.70-0.95), respectively. SGLT2-Is reduced the risk of all other cardiorenal outcomes in White and Asian populations, except for HF hospitalizations in Asians. No effects were observed in Black populations except for a reduced risk of HF hospitalizations by SGLT2-I. SGLT1-Is reduced the risk of composite CVD death/HF hospitalization in North America and Europe, whereas GLP1-RAs reduced the risk of MACE in Europe. GRADE certainty of evidence ranged from moderate to high.

CONCLUSIONS

There appears to be substantial racial/ethnic differences in the cardiorenal effects of SGLT2-Is and GLP1-RAs in patients with T2D, with consistent benefits observed among White and Asian populations and consistent lack of benefits in Black populations. Whether the differences are due to issues with under-representation of Black populations and low statistical power or racial/ethnic variations in the pharmacokinetics, pharmacodynamics and safety of SGLT2-Is and GLP1-RAs need further investigation.PROSPERO Registration: CRD42023401734.

Medical Assistant Health Coaching for Type 2 Diabetes in Primary Care: Results From a Pragmatic Cluster Randomized Controlled Trial

OBJECTIVE

This cluster (clinic-level) randomized controlled trial (RCT) compared medical assistant (MA) health coaching (MAC) with usual care (UC) among at-risk adults with type 2 diabetes in two diverse real-world primary care environments: a federally qualified health center (FQHC; Neighborhood Healthcare) and a large nonprofit private insurance-based health system (Scripps Health).

RESEARCH DESIGN AND METHODS

A total of 600 adults with type 2 diabetes who met one or more of the following criteria in the last 90 days were enrolled: HbA1c ≥8% and/or LDL cholesterol ≥100 mg/dL and/or systolic blood pressure (SBP) ≥140 mmHg. Participants at MAC clinics received in-person and telephone self-management support from a specially trained MA health coach for 12 months. Electronic medical records were used to examine clinical outcomes in the overall sample. Behavioral and psychosocial outcomes were evaluated in a subsample (n = 300).

RESULTS

All clinical outcomes improved significantly over 1 year in the overall sample (P < 0.001). The reduction in HbA1c was significantly greater in the MAC versus UC group (unstandardized Binteraction = -0.06; P = 0.002). A significant time by group by site interaction also showed that MAC resulted in greater improvements in LDL cholesterol than UC at Neighborhood Healthcare relative to Scripps Health (Binteraction = -1.78 vs. 1.49; P < 0.05). No other statistically significant effects were observed.

CONCLUSIONS

This was the first large-scale pragmatic RCT supporting the real-world effectiveness of MAC for type 2 diabetes in U.S. primary care settings. Findings suggest that this team-based approach may be particularly effective in improving diabetes outcomes in FQHC settings.

Factors Associated With the Cardiovascular Health of Black and Latino Adults With Type 2 Diabetes

AIMS

The purpose of this study was to assess the levels of cardiovascular health (CVH) of Black and Latino adults with type 2 diabetes (T2D) and examine the association of individual and microsystem level factors with their CVH score.

METHODS

This was a cross-sectional design in 60 Black and Latino Adults aged 18-40 with T2D. Data were collected on sociodemographic, individual (sociodemographic, diabetes self-management, sleep disturbance, depressive symptoms, quality of life, and the inflammatory biomarkers IL-6 and hs-CRP) and microsystem factors (family functioning), and American Heart Association's Life's Simple 7 metrics of CVH. Factors significantly associated with the CVH score in the bivariate analyses were entered into a linear regression model.

RESULTS

The sample had a mean age 34 ± 5 years and was primarily female (75%) with a mean CVH score was 8.6 ± 2.2 (possible range of 0-14). The sample achieved these CVH factors at ideal levels: body mass index <25 kg/m2 (8%); blood pressure <120/80 (42%); hemoglobin A1c < 7% (57%); total cholesterol <200 mg/dL (83%); healthy diet (18%); never or former smoker > one year (95%); and physical activity (150 moderate-to-vigorous minutes/week; 45%). In the multivariable model, two factors were significantly associated with cardiovascular health: hs-CRP (B = -0.11621, p < .0001) and the general health scale (B = 0.45127, p = .0013).

CONCLUSIONS

This sample had an intermediate level of CVH, with inflammation and general health associated with overall CVH score.

Subclinical Atherosclerosis to Guide Treatment in Dyslipidemia and Diabetes Mellitus

PURPOSE OF REVIEW

Dyslipidemia and type 2 diabetes mellitus are two common conditions that are associated with an increased risk of atherosclerotic cardiovascular disease (ASCVD). In this review, we aimed to provide an in-depth and contemporary review of non-invasive approaches to assess subclinical atherosclerotic burden, predict cardiovascular risk, and guide appropriate treatment strategies. We focused this paper on two main imaging modalities: coronary artery calcium (CAC) score and computed tomography coronary angiography.

RECENT FINDINGS

Recent longitudinal studies have provided stronger evidence on the relationship between increased CAC, thoracic aorta calcification, and risk of cardiovascular events among those with primary hypercholesterolemia, highlighting the beneficial role of statin therapy. Interestingly, resilient profiles of individuals not exhibiting atherosclerosis despite dyslipidemia have been described. Non-conventional markers of dyslipidemia have also been associated with increased subclinical atherosclerosis presence and burden, highlighting the contribution of apolipoprotein B-100 (apoB)-rich lipoprotein particles, such as remnant cholesterol and lipoprotein(a), to the residual risk of individuals on-target for low-density lipoprotein cholesterol (LDL-C) goals. Regarding type 2 diabetes mellitus, variability in atherosclerotic burden has also been found, and CAC testing has shown significant predictive value in stratifying cardiovascular risk. Non-invasive assessment of subclinical atherosclerosis can help reveal the continuum of ASCVD risk in those with dyslipidemia and diabetes mellitus and can inform personalized strategies for cardiovascular disease prevention in the primary prevention setting.

The Role of Family in Diabetes Management for Mexican American Adults

Introduction: The purpose of this study was to characterize how family influences diabetes self-management in Mexican American adults. Methods: Data were analyzed from previously collected data that included 34 semi-structured interviews with Hispanic adults with diabetes and six focus groups with 37 adults with diabetes and family members. Themes related to family and diabetes management were identified and analyzed using a modified template approach. Results: Family-related facilitators to T2DM self-management were (1) provides support, (2) provides motivation, and (3) desire to protect family from diabetes. Family-related challenges were (1) lack of support, (2) family responsibilities, and (3) stress related to family. Diabetes education was shared with family members. Family member perspectives on T2DM included (1) not knowing how to help, (2) effect on emotional wellbeing, (3) diabetes affects the whole family, and (4) family provides support. Conclusion: Most participants with T2DM felt supported by family, but many desired more social support and support surrounding dietary changes from family. Many felt family did not understand what living with diabetes meant for them. Most family members wished to learn more about how to help. Future interventions should include family members and teach them supportive strategies to support beneficial diabetes self-management behaviors.

A qualitative exploration of facilitators and barriers to adopting a healthy lifestyle among Black, Hispanic, and American Indian males with diabetes or at risk for type 2 diabetes

OBJECTIVES

Higher prevalence of several chronic diseases occurs in men in the United States, including diabetes and prediabetes. Of the 34 million adults with diabetes and 88 million with prediabetes there is a higher prevalence of both conditions in men compared to women. Black, Hispanic, and American Indian men have some of the highest rates of diabetes and diabetes complications. Adopting a healthy lifestyle including healthy eating and physical activity, is important in preventing type 2 diabetes and diabetes complications.

DESIGN

This study included six focus groups that explored facilitators and barriers to adopting a healthy lifestyle in Black, Hispanic, and American Indian men with diabetes or at risk for type 2 diabetes. Thematic analysis was used to identify facilitators and barriers to adopting a healthy lifestyle.

RESULTS

Participants included males 18 years of age and older identifying as Black, Hispanic, or American Indian and diagnosed with prediabetes, diabetes, hypertension, or otherwise at risk for type 2 diabetes. Thirty-seven men participated, 19 diagnosed with diabetes and 18 at risk for type 2 diabetes. Fourteen Black, 14 Hispanic, and 9 American Indian men participated. The themes of facilitators to a healthy lifestyle included: family and the social network; psychosocial factors; health status, health priorities and beliefs about aging; knowledge about health and healthy behavior; and healthy community resources. Themes of barriers to a healthy lifestyle also included: mistrust of the health care system, cost, and low socioeconomic status.

CONCLUSIONS

This study underscores the complexity of factors involved in adopting a healthy lifestyle for some racial and ethnic minority men with diabetes or at risk for type 2 diabetes.

Disparities in prevalence and treatment of diabetes, cardiovascular and chronic kidney diseases - Recommendations from the taskforce of the guideline workshop

There is a mounting clinical, psychosocial, and socioeconomic burden worldwide as the prevalence of diabetes, cardiovascular disease (CVD), and chronic kidney disease (CKD) continues to rise. Despite the introduction of therapeutic interventions with demonstrated efficacy to prevent the development or progression of these common chronic diseases, many individuals have limited access to these innovations due to their race/ethnicity, and/or socioeconomic status (SES). However, practical guidance to providers and healthcare systems for addressing these disparities is often lacking. In this article, we review the prevalence and impact of healthcare disparities derived from the above-mentioned chronic conditions and present broad-based recommendations for improving access to quality care and health outcomes within the most vulnerable populations.

Screening for Nephropathy in Pediatric Type 2 Diabetes: Quality Improvement to Increase Nephropathy Screening

Background

Screening for early detection of microalbuminuria signaling kidney disease should begin as early as the time of diagnosis of youth-onset type 2 diabetes. This quality improvement initiative aimed to standardize urine nephropathy screening in pediatric patients with type 2 diabetes at a tertiary academic medical center and increase a baseline screening rate of 56%-75% over 6 months (September 2022-February 2023) and sustain that increase for 6 months (March through August 2023).

Methods

A multi-disciplinary team used quality improvement methods and iterative Plan-Do-Study-Act cycles. Targeted interventions included previsit planning workflow, education, and a new-onset triage protocol. The team collected data at baseline and prospectively by reviewing electronic medical records. The primary outcome measure was pediatric type 2 diabetes clinic visits in diabetes clinic with urine nephropathy screening before or on the visit date.

Results

A total of 121 youth were scheduled for T2D clinic visits between September 2021 and August 2023. The mean age was 14.5 years, and 60% were women, 40% were non-Hispanic Black, 28% were Hispanic/Latino, and 15% reported Spanish as their preferred language. Following the interventions of this project, urine nephropathy screening increased from 56% to 75%, and this change was sustained for 6 months.

Conclusions

Interventions focused on efficient recognition of the population needing screening, coordinated internal processes around screening, a shared understanding between all stakeholders, and practical support in the healthcare system increased urine nephropathy screening with sustained improvement.

Black women's perspectives on bladder health: Social-ecological and life course contexts

AIMS

This paper explores Black women's perspectives on bladder health using a social-ecological conceptual framework and life course perspective.

METHODS

We conducted a directed content analysis of data from the Study of Habits, Attitudes, Realities, and Experiences (SHARE), a focus group study by the Prevention of Lower Urinary Tract Symptoms (PLUS) Research Consortium. Analysis was conducted on data from five focus groups and a member-checking session where all participants self-identified as Black or African American.

RESULTS

Forty-two participants aged 11-14 or 45+ years reported life course experiences with their bladder. The intersection of race and gender was the lens through which participants viewed bladder health. Participants' accounts of their perspectives on bladder health explicitly and implicitly revealed structural racism as an explanatory overarching theme. Participants described (a) historically-rooted and still pervasive practices of discrimination and segregation, engendering inequitable access to quality medical care and public facilities, (b) institutional barriers to toileting autonomy in educational and occupational settings, promoting unhealthy voiding habits, (c) internalized expectations of Black women's stereotyped role as family caregiver, compromising caregiver health, (d) lack of reliable information on bladder health, leading to unhealthy bladder behaviors, and (e) potentially stress-related comorbid chronic conditions and associated medication use, causing or exacerbating bladder problems.

CONCLUSIONS

Bladder health promotion interventions should address social-ecological and life course factors shaping Black women's bladder health, including social and structural barriers to accessing equitable health information and medical care.

Outcomes of an Asynchronous Care Model for Chronic Conditions in a Diverse Population: 12-Month Retrospective Chart Review Study

BACKGROUND

Diabetes and hypertension are some of the most prevalent and costly chronic conditions in the United States. However, outcomes continue to lag behind targets, creating further risk of long-term complications, morbidity, and mortality for people living with these conditions. Furthermore, racial and ethnic disparities in glycemic and hypertension control persist. Flexible telehealth programs leveraging asynchronous care allow for increased provider access and more convenient follow-up, ultimately improving critical health outcomes across demographic groups.

OBJECTIVE

We aim to evaluate the 12-month clinical outcomes of participants in the 9amHealth web-based clinic for diabetes and hypertension. We hypothesized that participation in the 9amHealth program would be associated with significant improvements in glycemic and blood pressure (BP) control across a diverse group of individuals.

METHODS

We enrolled 95 patients in a completely web-based care clinic for diabetes and hypertension who received nutrition counseling, health coaching, and asynchronous physician consultations for medication prescribing. Patients received standard or cellular-connected glucose meters and BP cuffs in order to share data. Laboratory tests were completed either with at-home phlebotomy draws or a self-administered test kit. Patients' first and last hemoglobin A1c (HbA1c) and BP results over the 12-month period were compared, and analyses were repeated across race and ethnicity groups.

RESULTS

Among all 95 patients, the average HbA1c decreased by -1.0 (from 8.2% to 7.2%; P<.001) over 12 months of program participation. In those with a baseline HbA1c >8%, the average HbA1c decreased by -2.1 (from 10.2% to 8.1%; P<.001), and in those with a baseline HbA1c >9%, the average HbA1c decreased by -2.8 (from 11% to 8.2%; P<.001). Among participants who identified as a race or ethnicity other than White, the HbA1c decreased by -1.2 (from 8.6% to 7.4%, P=.001). Further examination of subgroups confirmed HbA1c lowering within each race or ethnicity group. In the overall population, the average systolic BP decreased by 17.7 mm Hg (P=.006) and the average diastolic BP decreased by 14.3 mm Hg (P=.002). Among participants self-identifying as a race or ethnicity other than White, the results similarly showed a decrease in BP (average reduction in systolic BP of 10 mm Hg and in diastolic BP of 9 mm Hg).

CONCLUSIONS

A fully web-based model leveraging all-asynchronous physician review and prescribing, combined with synchronous and asynchronous coaching and nutrition support, was associated with clinically meaningful improvement in HbA1c and BP control over a 12-month period among a diverse group of individuals. Further studies should prospectively evaluate the effectiveness of such models among larger populations, assess the longer-term sustainability of these outcomes, and explore financial models to make these types of programs broadly accessible.

Paving a Path to Equity in Cardiorenal Care

Cardiorenal syndrome encompasses a dynamic interplay between cardiovascular and kidney disease, and its prevention requires careful examination of multiple predisposing underlying conditions. The unequal distribution of diabetes, heart failure, hypertension, and kidney disease requires special attention because of the influence of these conditions on cardiorenal disease. Despite growing evidence regarding the benefits of disease-modifying agents (e.g., sodium-glucose cotransporter 2 inhibitors) for cardiovascular, kidney, and metabolic (CKM) disease, significant disparities remain in access to and utilization of these essential therapeutics. Multilevel barriers impeding their use require multisector interventions that address patient, provider, and health system-tailored strategies. Burgeoning literature also describes the critical role of unequal social determinants of health, or the sociopolitical contexts in which people live and work, in cardiorenal risk factors, including heart failure, diabetes, and chronic kidney disease. This review outlines (i) inequality in the burden and treatment of hypertension, type 2 diabetes, and heart failure; (ii) disparities in the use of key disease-modifying therapies for CKM diseases; and (iii) multilevel barriers and solutions to achieve greater pharmacoequity in the use of disease-modifying therapies. In addition, this review provides summative evidence regarding the role of unequal social determinants of health in cardiorenal health disparities, further outlining potential considerations for future research and intervention. As proposed in the 2023 American Heart Association presidential advisory on CKM health, a paradigm shift will be needed to achieve cardiorenal health equity. Through a deeper understanding of CKM health and a commitment to equity in the prevention, detection, and treatment of CKM disease, we can achieve this critical goal.

A, Clare C. B, Corey J. H, Hari E. The association between rurality, dual Medicare/Medicaid eligibility and chronic conditions with telehealth utilization: An analysis of 2019-2020 national Medicare claims

INTRODUCTION

Telehealth services have the potential to increase healthcare access among underserved populations, such as rural residents and racial/ethnic minority groups. The COVID-19 public health emergency led to unprecedented growth in telehealth utilization, but evidence suggests the growth has not been equitable across all patient populations. This study aimed to explore whether telehealth utilization and expansion changed equitably from 2019 to 2020 among sub-groups of Medicare beneficiaries.

METHODS

We conducted an analysis of telehealth utilization among a 20% random sample of 2019-2020 Medicare beneficiaries on a national level. We fit multivariable logistic regression models and calculated average marginal effects (AME) to assess the association between demographic and clinical characteristics on telehealth utilization.

RESULTS

We found telehealth utilization was less likely among non-Hispanic Black/African-American (2019: adjusted odds ratio [aOR] = 0.77, AME = -0.15; 2020: aOR = 0.85, AME = -3.50) and Hispanic (2019: aOR = 0.79, AME = -0.13; 2020: aOR = 0.87, AME = -2.89) beneficiaries, relative to non-Hispanic White beneficiaries in both 2019 and 2020, with larger disparities in 2020. Rural beneficiaries were more likely to utilize telehealth than urban beneficiaries in 2019 (aOR = 2.62, AME = 0.84), but less likely in 2020 (aOR = 0.57, AME = -14.47). In both years, dually eligible Medicare/Medicaid beneficiaries were more likely than non-dually eligible beneficiaries to utilize telehealth (2019: aOR = 4.75, AME = 0.84; 2020: aOR = 1.34, AME = 2.25). However, the effects of dual eligibility and rurality changed in both models as the number of chronic conditions increased.

DISCUSSION

We found evidence of increasing disparities in telehealth utilization among several Medicare beneficiary sub-groups in 2020 relative to 2019, including individuals of minority race/ethnicity, rural residents, and dually eligible beneficiaries, with disparities increasing among individuals with more chronic conditions. Although telehealth has the potential to address health inequities, our findings suggest that many of the patients in greatest need of healthcare are least likely to utilize telehealth services.

Comparative study of the vascular structures of the retina and choroid in Chinese Han and Uygur populations with proliferative diabetic retinopathy: An OCTA study

BACKGROUND

To compare the vascular structures of the retina and choroid in Chinese Han and Uygur populations with proliferative diabetic retinopathy (PDR) using swept-source OCTA (SS-OCTA).

METHODS

Fifty-three eyes of 53 healthy volunteers (25 from Hans and 28 from Uygurs) and 40 eyes of 40 PDR patients (20 from Hans and 20 from Uygurs) were included. Retinal and choroidal parameters, including thickness, vessel flow density (VFD), foveal avascular zone (FAZ) area, choroidal vascularity volume and index (CVV and CVI) were evaluated.

RESULTS

Compared with the respective controls, superficial capillary plexus (SCP)-VFD and deep capillary plexus (DCP)-VFD, the areas of FAZ in SCP and DCP were significantly decreased in both Han and Uygur PDR patients. choroidal parameters analysis found that Uygur controls had substantially higher choroidal thickness (CT) than Han controls (p = 0.020) and PDR eyes showed significantly decreased CT. Both races with PDR exhibited significantly reduced choriocapillaris layer-VFD, large and medium choroidal vessel (LMCV) layer-VFD, CVV and CVI, however, Uygur PDR patients had significant lower LMCV layer-VFD, CVV and CVI compared to Han PDR patients. Diabetes duration was the most significant factor affecting CVV and CVI.

CONCLUSION

Both Han and Uygur PDR patients had significantly lower CT and decreased vessel densities compared to controls, but the Uygur PDR patients had more severe choroidal damage than Han PDR patients, which is most likely related to worse visual prognosis. These findings indicate that more frequent screenings and prompt therapy are urgent for Uygur PDR patients.

Coping With Discrimination Among African Americans With Type 2 Diabetes: Factor Structure and Associations With Diabetes Control, Mental Distress, and Psychosocial Resources

Introduction

Type 2 diabetes undermines diabetes-related health outcomes among African Americans, who have a disproportionately high incidence of the disease. Experiences of discrimination are common among African Americans and compound diabetes-related stress, exacerbating poor health outcomes. Appropriate use of coping strategies may mitigate the detrimental effect of discrimination on diabetes-related outcomes, but examining associations between coping strategies and health outcomes is needed to inform potential interventions. This study assessed the factor structure of the Coping with Discrimination Scale (CDS) among African American adults with type 2 diabetes and examined associations of CDS subscales with measures of diabetes control, mental distress, and psychosocial resources.

Methods

The CDS was administered primarily through churches to African Americans with type 2 diabetes residing in Austin, Texas, and surrounding areas. Data were collected from August 2020 through April 2023. We conducted principal axis factor analysis of the CDS and determined internal consistency for each factor. We computed bivariate and partial correlations between CDS subscales and indicators of diabetes control (hemoglobin A1c, diabetes self-management), mental distress (diabetes distress, perceived stress, depressive symptoms), and psychosocial resources (resilience, social support, self-efficacy).

Results

The 284 African American adults (204 women, 80 men) ranged in age from 23 to 86 years (mean [SD] = 62 [11] y). We identified 4 factors: education/advocacy, internalization, strong response, and detachment. Scores were highest for education/advocacy items and lowest for strong response items. Education/advocacy was associated with higher scores on psychosocial resources, whereas detachment was associated with lower scores. Internalization and strong response were associated with higher mental distress. Strong response was associated with higher hemoglobin A1c, and education/advocacy was associated with enhanced diabetes self-management.

Conclusion

We suggest health care professionals create culturally tailored interventions that aid individuals in educating others, advocating for themselves, or recognizing situations outside one's control and detaching from responsibility, rather than internalizing experiences of discrimination or engaging in strong responses that upon reflection are detrimental to one's health.

Evaluation and Optimization of Diabetic Retinopathy Screenings for Uninsured Latinx Patients in a Resource-Limited Student-Run Free Clinic

Background

Diabetic retinopathy (DR) is a sight-threatening condition that causes progressive retina damage. Student-run free clinics represent a valuable opportunity to provide DR screenings to high-risk populations. We characterized the patient population, evaluated the performance, and conducted a needs assessment of DR screenings at the University of California, San Diego Student-Run Ophthalmology Free Clinic, which provides care to predominantly uninsured, Latino patients.

Methods

Retrospective chart review was conducted of all patients seen at the free clinic since 2019 with a diagnosis of type II diabetes. Date and outcome of all DR-related screenings or visits from 2015 onward, demographics information, and DR risk factors such as A1c and insulin dependence were recorded. Predictors of diabetic retinopathy and frequency of DR screenings for each patient were analyzed using multiple logistic regression, t-test for equality of means, and Pearson's correlation.

Results

Of 179 uninsured diabetic patients receiving care at the free clinic, 71% were female and average age was 59. 83% had hypertension, 93% had hyperlipidemia, and 79% had metabolic syndrome. Prevalence of non-proliferative DR was 34% and that of proliferative DR was 15% in diabetic patients. The free clinic capacity in recent years plateaued at just under 50% of patients seen for DR screening or visit per year, though average wait time was over 2 years between visits. Patients with higher no-show rates had less frequent DR screenings. Chronic kidney disease and poor glycemic control were the strongest predictors of DR.

Conclusion

The student-run free ophthalmology clinic has been effective in providing screening and follow-up care for DR patients. Creation of a protocol to identify which patients are at highest risk of DR and should be seen more urgently, addressing no-shows, and implementation of a tele-retina program are potential avenues for improving clinic efficiency in a resource-limited setting for vulnerable populations.

Understanding the Relationship Between Wealth and Cognitive Function by Race/Ethnicity Among Older United States Adults with Diabetes

Background

The prevalence of type 2 diabetes is increasing with the burden disproportionately falling on older adults and racial/ethnic minorities. Older adults with diabetes show greater cognitive decline and there are disparities in cognitive function by race/ethnicity that can be explained by social determinants such as wealth.

Objective

To understand whether there is a differential relationship between wealth and cognitive function by race/ethnicity among older U.S. adults with diabetes.

Methods

Data on 9,006 adults aged 50+ with diabetes from the Health and Retirement Study (2006-2016) were analyzed. The primary outcome, cognitive function, was a score ranging from range 0-27 categorized as: normal [12-27], mild cognitive impairment (MCI) [7-11], and dementia including Alzheimer's disease [0-6]. Three modeled outcomes were: 1) normal versus MCI, 2) normal versus dementia, 3) MCI versus dementia. Wealth was log transformed and used as continuous and binary (≥median,

Results

In adjusted models, greater wealth was significantly associated with lower odds of MCI and dementia for all groups. Similarly, having wealth less than the sample median was associated with higher odds of MCI and dementia compared to wealth≥sample median.

Conclusions

Increased wealth was significantly protective against MCI and dementia for all ethnic groups. Wealth less than the sample median was associated with greater odds of dementia for NHB and NHW.

Diabetes and Hospitalizations Among Mexican Americans Aged 75 Years and Older

OBJECTIVE

To examine factors associated with hospitalization among Mexican Americans aged 75 years and older with diabetes (with and without complications) and without diabetes over 12 years of follow up.

METHODS

Participants (N = 1454) were from the Hispanic Established Population for the Epidemiologic Study of the Elderly (2004/2005-2016) residing in Arizona, California, Colorado, New Mexico, and Texas. Measures included socio-demographics, medical conditions, falls, depressive symptoms, cognitive function, disability, physician visits, and hospitalizations. Participants were categorized as no diabetes (N = 1028), diabetes without complications (N = 180), and diabetes with complications (N = 246).

RESULTS

Participants with diabetes and complications had greater odds ratio (1.56, 95% Confidence Interval = 1.23-1.98) over time of being admitted to the hospital in the prior year versus those without diabetes. Participants with diabetes had greater odds of hospitalization if they had heart failure, falls, amputation, and insulin treatment.

CONCLUSIONS

In Mexican American older adults, diabetes and diabetes-related complications increased the risk of hospitalization.
