Telehealth is a promising intervention for hypertension management and control and was rapidly adopted by health systems to ensure continuity of care during the COVID-19 pandemic. Rapid evaluations of telehealth strategies at 2 US health systems explored how telehealth affected health care access and blood pressure outcomes among populations disproportionately affected by hypertension. Both health systems implemented telehealth strategies to maintain continuity of health care services during the COVID-19 pandemic. The evaluations used a mixed-method approach; qualitative interviews were conducted with key staff, and quantitative analyses were performed on patient electronic health record data. Both health systems exhibited similar trends in telehealth use, which allowed for continued access to health care for some patients but hindered other patients who had limited access to the internet or the equipment needed. Telehealth provides opportunities for blood pressure control and management. Further evaluation is needed to understand the role of broadband internet access as a social determinant of health and its impact on equitable patient access to health care.
