Sociodemographic disparities in the use of cardiovascular ambulatory care and telemedicine during the COVID-19 pandemic.
Researchers examined adult cardiology visits at an academic and affiliated community practice in Northern California to assess the persistence sociodemographic disparities in telemedicine use before and during the COVID pandemic. Results indicated that sociodemographic characteristics of patients receiving cardiovascular care remained stable during both periods, but the modality of care diverged across groups. Observed disparities in the use of video-based telemedicine were greatest for patients 80 years or older, Black, with limited English proficiency, or on Medicaid. The researchers recommended that future studies examine barriers and outcomes in digital healthcare access across diverse patient groups.

Mixed signals in child and adolescent mental health and well-being indicators in the United States: a call for improvements to population health monitoring.
The authors of this paper suggest that policies targeting social indicators of youth status may not have improved overall mental health and well-being. They contend this absence of impact is evidenced by the divergence between social indicators which are improving, such as high school graduation, food insecurity, and smoking, and those which are worsening, such as mental health and well-being. The researchers report that available data indicates that one or more common exposures may be to blame, including those inadequately captured by existing social indicators.

Application of the quadruple aim to evaluate the operational impact of a telemedicine program.
This study compared the operational impact of a telemedicine program called CardioClick at a preventive cardiology clinic compared to traditional clinic visits. The authors examined data for 134 patients enrolled in CardioClick with 181 video follow-up visits and 276 patients enrolled in the clinic’s traditional program with 694 in-person follow-up visits. The Quadruple Aim was used to evaluate CardioClick. Both cohorts were similar in characteristics in terms of age, gender balance, and baseline clinical characteristics. Video follow-up visits were shorter in time for clinicians (median 22 vs 30 minutes) than in-person visits and total clinic time (median 22 vs 68 minutes). Video visits were more likely to end on time than in-person visits as well. Physicians more often completed video visit documentation on the day of the visit.

National trends in telestroke utilization in a US commercial platform prior to the COVID-19 pandemic.
In this study, the objective was to describe characteristics of telestroke consultations among a national sample of telestroke sites on one of the most commonly used common vendor platforms, prior to the COVID-19 public health emergency. The investigators concluded that among spoke sites using a commercial telestroke platform over a seven-year time horizon, times to consult start and alteplase bolus decreased over time. Similar to academic networks, duration of telestroke participation in this commercial network was associated with faster alteplase delivery, suggesting practice improves performance.

Regional changes in patterns of stroke presentation during the COVID-19 pandemic.
The authors sought to determine the effect of the coronavirus pandemic on patterns of stroke patient presentation and quality of care. They analyzed data from 25 New England hospitals: one urban, academic, comprehensive stroke center and telestroke hub, and 24 spoke hospitals in the same telestroke network. They included all telestroke consultations from the 24 spokes, and stroke admissions to the comprehensive stroke center hub from November 2019 through April 2020. They compared rates of presentation, timeliness presentation, and quality of care pre- versus post-March 2020. They also examined trends in patient demographics, stroke severity, timeliness, diagnosis including large vessel occlusion, alteplase use, and endovascular thrombectomy among eligible subjects. Among 1248 patient presentations, telestroke consultations and ischemic stroke patient admissions decreased through the hub and spoke network. Age and stroke severity were unchanged during the study period. However, rates of adherence for the quality measures dysphagia screening, early antithrombotic initiation, and early venous thromboembolism prophylaxis were reduced during the pandemic.
