Item Open Access Clinical factors associated with persistently poor diabetes control in the Veterans Health Administration: A nationwide cohort study.(PloS one, 2019-01) Alexopoulos, Anastasia-Stefania; Jackson, George L; Edelman, David; Smith, Valerie A; Berkowitz, Theodore SZ; Woolson, Sandra L; Bosworth, Hayden B; Crowley, Matthew JObjective
Patients with persistent poorly-controlled diabetes mellitus (PPDM) despite engagement in clinic-based care are at particularly high risk for diabetes complications and costs. Understanding this population's demographics, comorbidities and care utilization could guide strategies to address PPDM. We characterized factors associated with PPDM in a large sample of Veterans with type 2 diabetes.Methods
We identified a cohort of Veterans with medically treated type 2 diabetes, who received Veterans Health Administration primary care during fiscal years 2012 and 2013. PPDM was defined by hemoglobin A1c levels uniformly >8.5% during fiscal year (FY) 2012, despite engagement with care during this period. We used FY 2012 demographic, comorbidity and medication data to describe PPDM in relation to better-controlled diabetes patients and created multivariable models to examine associations between clinical factors and PPDM. We also constructed multivariable models to explore the association between PPDM and FY 2013 care utilization.Results
In our cohort of diabetes patients (n = 435,820), 12% met criteria for PPDM. Patients with PPDM were younger than better-controlled patients, less often married, and more often Black/African-American and Hispanic or Latino/Latina. Of included comorbidities, only retinopathy (OR 1.68, 95% confidence interval (CI): 1.63,1.73) and nephropathy (OR 1.26, 95% CI: 1.19,1.34) demonstrated clinically significant associations with PPDM. Complex insulin regimens such as premixed (OR 10.80, 95% CI: 10.11,11.54) and prandial-containing regimens (OR 18.74, 95% CI: 17.73,19.81) were strongly associated with PPDM. Patients with PPDM had higher care utilization, particularly endocrinology care (RR 3.56, 95% CI: 3.47,3.66); although only 26.4% of patients saw endocrinology overall.Conclusion
PPDM is strongly associated with complex diabetes regimens, although heterogeneity in care utilization exists. While there is evidence of underutilization, inadequacy of available care may also contribute to PPDM. Our findings should inform tailored approaches to meet the needs of PPDM, who are among the highest-risk, highest-cost patients with diabetes.Item Open Access Effectiveness of Synchronous Postdischarge Contacts on Health Care Use and Patient Satisfaction : A Systematic Review and Meta-analysis.(Ann Intern Med, 2025-01-14) Boggan, Joel C; Sankineni, Spoorthi; Dennis, Paul A; Chen, Dazhe; Sledge, Tina Wong; Halpern, David; Rushton, Sharron; Williams, John W; Der, Tatyana; Tabriz, Amir Alishahi; Gordon, Adelaide M; Jacobs, Morgan; Boucher, Nathan A; Colandrea, Maria; Alexopoulos, Anastasia-Stefania; Roman Jones, Joanne; Leflore-Lloyd, Nina; Cantrell, Sarah; Goldstein, Karen M; Gierisch, Jennifer MBACKGROUND: Postdischarge contacts (PDCs) after hospitalization are common practice, but their effectiveness in reducing use of acute care after discharge remains unclear. PURPOSE: To assess the effects of PDC on 30-day emergency department (ED) visits, 30-day hospital readmissions, and patient satisfaction. DATA SOURCES: MEDLINE, Embase, and CINAHL searched from 2012 to 25 May 2023. STUDY SELECTION: Randomized and nonrandomized trials of PDC within 7 days. DATA EXTRACTION: Two investigators independently screened articles and assessed risk of bias (ROB). Single reviewers extracted data, with verification by second investigators. Random-effects meta-analyses were done on outcomes shared by at least 3 studies, and the certainty of evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) framework. DATA SYNTHESIS: Of 13 included studies (11 randomized trials [RTs]), 12 delivered PDCs via telephone. Three of 11 RTs were rated as having low ROB, with 1 rated high. Most PDC interventions (n = 10) consisted of single telephone contacts, often within 3 days. Eight studies focused on patients identified as higher-risk by the authors. There were no differences in 30-day ED use (5 RTs; 3054 patients; risk difference, 0.00 [95% CI, -0.02 to 0.03]; moderate certainty) or 30-day hospital readmissions (7 RTs; 7075 patients; risk difference, 0.00 [CI, -0.02 to 0.02]; moderate certainty) with PDC. LIMITATION: Adherence and fidelity to PDC interventions were poorly described, and only 1 study investigated nontelephone PDC. CONCLUSION: Postdischarge contacts within 7 days of discharge were not associated with reductions in 30-day ED use or readmissions compared with usual care. Health systems should reconsider the utility of universal PDCs because multifaceted interventions targeting higher-risk patients may be necessary to reduce use of acute care after discharge.

Whether glycemic control, as opposed to diabetes status, is associated with the severity of nonalcoholic fatty liver disease (NAFLD) is unknown. We aimed to evaluate whether degree of glycemic control in the years preceding liver biopsy predicts the histologic severity of nonalcoholic steatohepatitis (NASH).Methods & results
Using the Duke NAFLD Clinical Database we examined patients with biopsy-proven NAFLD/NASH (n=713) and the association of liver injury with glycemic control as measured by hemoglobin A1c (HbA1c). The study cohort was predominantly female (59%), Caucasian (84%) with median (IQR) age of 50 (42, 58) years; 49% had diabetes (n=348). Generalized linear regression models adjusted for age, sex, race, diabetes, body mass index, and hyperlipidemia were used to assess the association between mean HbA1c over the year preceding liver biopsy and severity of histologic features of NAFLD/NASH. Histologic features were graded and staged according to NASH Clinical Research Network system. Group-based trajectory analysis was used to examine patients with ≥3 HbA1c (n=298) measures over 5 years preceding clinically indicated liver biopsy. Higher mean HbA1c was associated with higher grade of steatosis and ballooned hepatocytes, but not lobular inflammation. Every 1% increase in mean HbA1c was associated with 15% higher odds of increased fibrosis stage (OR 1.15, 95% CI 1.01, 1.31). As compared with good glycemic control, moderate control was significantly associated with increased severity of ballooned hepatocytes (OR 1.74, 95% CI 1.01, 3.01, p=0.048) and hepatic fibrosis (OR 4.59, 95% CI 2.33, 9.06, p<0.01).Conclusions
Glycemic control predicts severity of ballooned hepatocytes and hepatic fibrosis in NAFLD/NASH, and thus optimizing glycemic control may be a means of modifying risk of NASH-related fibrosis progression.Item Open Access Racial Differences in the Effectiveness of a Multifactorial Telehealth Intervention to Slow Diabetic Kidney Disease.(Medical care, 2020-11) Kobe, Elizabeth A; Diamantidis, Clarissa J; Bosworth, Hayden B; Davenport, Clemontina A; Oakes, Megan; Alexopoulos, Anastasia-Stefania; Pendergast, Jane; Patel, Uptal D; Crowley, Matthew JBackground
African Americans are significantly more likely than non-African Americans to have diabetes, chronic kidney disease, and uncontrolled hypertension, increasing their risk for kidney function decline.Objective
The objective of this study was to compare how African Americans and non-African Americans with diabetes responded to a multifactorial telehealth intervention designed to slow kidney function decline.Research design
Secondary analysis of a randomized trial. Primary care patients (N=281, 56% African American) were allocated to either: (1) a multifactorial, pharmacist-delivered phone-based telehealth intervention focused on behavioral and medication management of diabetic kidney disease; or (2) an education control.Measures
The primary study outcome was change in estimated glomerular filtration rate (eGFR). Linear mixed models were used to explore the moderating effect of race on the relationship between study arm and eGFR decline over time; the mean annual rate of eGFR decline was estimated by race and study arm.Results
Findings demonstrated a differential intervention effect on kidney function over time by race (Pinteraction=0.005). Among African Americans, the intervention arm had significantly greater preservation of eGFR over time than the control arm (difference in the annual rate of eGFR decline=1.5 mL/min/1.73 m; 95% confidence interval: 0.04, 3.02). For non-African Americans, the intervention arm had a faster decline in eGFR over time than the control arm (difference in the annual rate of eGFR decline=-1.7 mL/min/1.73 m; 95% confidence interval: -3.3, -0.02).Conclusion
A multifactorial, pharmacist-delivered telehealth intervention for diabetic kidney disease may be more effective for slowing eGFR decline among African Americans than non-African Americans.Item Open Access Specialist Perspectives on Delivering High-Quality Telemedicine for Diabetes: A Mixed Methods Survey Study.(Journal of the Endocrine Society, 2023-03) Zupa, Margaret F; Alexopoulos, Anastasia-Stefania; Esteve, Lucy; Rosland, Ann-MarieBackground
Recent recommendations guiding appropriate use of telemedicine for endocrinology care have largely relied on expert opinion due to limited evidence on factors that increase quality of telemedicine care. In this study, we assessed the perspectives of front-line specialists on factors and strategies perceived to increase quality of diabetes care delivered via telemedicine after more than 2 years of widespread use.Methods
Adult diabetes specialists in 2 academic health systems who recently used video-based telemedicine to provide diabetes care were invited to participate in an online survey study between March and April 2022. Likert-style questions, followed by related open-ended questions, assessed perspectives on availability of key resources, factors affecting quality, and anticipated benefits from telemedicine for diabetes.Results
Response rate was 52% (56/111). More than half (54%) of participants reported better overall quality of diabetes care with face-to-face care vs telemedicine. Participants reported clinical data supporting high-quality care, such as home blood glucose readings and vital signs, were often not available with telemedicine. Patient factors, including comorbidities and communication barriers, reduced anticipated benefit from telemedicine, while geographic and mobility barriers increased expected benefit. Providers described multiple health care setting resources that could promote high-quality telemedicine diabetes care, including greater support for sharing patient-generated health data and coordinating multidisciplinary care.Conclusions
After 2 years of sustained use, diabetes specialists identified telemedicine as an important way to enhance access to care. However, specialists identified additional supports needed to increase appropriate use and delivery of high-quality telemedicine care for patients with complex clinical needs.
