BACKGROUND
Lack of healthcare access to due to physician shortages is a significant driver of telemedicine expansion in rural areas. Telemedicine is effective for management of chronic conditions such as diabetes but its effectiveness in primary care settings is unknown.
OBJECTIVE
To evaluate differences in diabetes care before and after implementation of a longitudinal virtual primary care program.
DESIGN
Propensity score-matched cohort study utilizing difference-in-differences analysis.
PARTICIPANTS
Patients with diabetes who received care at VA primary care clinics between January 2018 and December 2019 where the Virtual Integrated Multisite Patient Aligned Care Teams (V-IMPACT) program was implemented.
EXPOSURE
Patient participation in at least one V-IMPACT visit while usual care patients did not participate in V-IMPACT.
MAIN MEASURES
The primary outcome was change in hemoglobin A1C (HbA1C) and secondary outcomes included change in the proportion of patients meeting diabetes quality indicators: blood pressure control, statin use, angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers (ACEi/ARB) use, and annual microalbuminuria testing.
KEY RESULTS
Our propensity-matched cohort included 9010 patients split evenly between those who participated in V-IMPACT and those who remained in usual in-person care. Among individuals with diabetes who participated in V-IMPACT, the change in mean HbA1C was - 0.055% (95% CI - 0.088 to - 0.022%) while those in usual care had a - 0.047% (95% CI - 0.080 to - 0.014%) change before and after program implementation. We observed a 5.1% (95% CI 2.4 to 7.7%) absolute increase in the proportion prescribed statins in the V-IMPACT group, a 5.3% (95% CI 2.5 to 8.2%) increase prescribed ACE/ARBs, and a 4.6% (95% 1.7 to 7.5%) increase in completed yearly microalbuminuria testing. V-IMPACT was not associated with a significant difference in the proportion with controlled blood pressure at < 140/90 or < 130/90 mmHg thresholds.
CONCLUSIONS
Quality of diabetes care delivered by a longitudinal virtual primary care model was similar if not better than traditional in-person care.

Multiple aspects of Black young men who have sex with men's (YMSM) identities cause them to be differentially targeted for arrest and incarceration. However, limited research has explored structural drivers of Black YMSM' criminal justice involvement, particularly co-occurring forms of discrimination. This article examines the temporal relationship between perceived racial discrimination, perceived sexual orientation discrimination, and community-level HIV discrimination and criminal justice involvement among Black YMSM in North Carolina. The study followed 465 Black YMSM from November 2013 to October 2016 who were recruited for a randomized controlled trial to test an internet-based intervention for Black YMSM living with, and at risk for HIV; participants completed online surveys at baseline, 3, 6, and 12 months. Logistic regression was used to explore the relationship between the three predictors at baseline (i.e., perceived racism and sexual orientation discrimination and community-level HIV discrimination) and criminal justice involvement at follow-up. All three predictor variables were significantly associated with subsequent criminal justice involvement in separate regression models that adjusted for other covariates: HIV discrimination (aOR = 1.06 [1.01-1.11]), perceived sexual orientation discrimination (aOR = 1.12 [1.00-1.27]), and perceived racism (aOR = 1.26 [1.12-1.42]). Perceived racism remained significant in the model with all three predictors (aOR = 1.29 [1.07-1.55]). Racism did not modify the relationship between HIV discrimination and perceived sexual orientation discrimination and criminal justice involvement. This study expands existing research by exploring racism as a structural driver of criminal justice involvement; we subsequently examined whether racism modified the effect of the two other predictors. It also contributes to research on co-occurring discrimination by examining their impact on an underrepresented population.
