New Study Finds Hypertension Management Similar via Telehealth, In-Person

October 27, 2022

When it comes to controlling patients’ high blood pressure, it appears telehealth is just as effective as in-person care, according to a new study from HealthPartners Institute that was published in the journal, Hypertension.  

The study was completed before the COVID-19 pandemic hit.  

“When COVID hit in 2020 and telehealth exploded, many people wondered whether it was as effective or how it would impact outcomes,” said Karen Margolis, MD, senior researcher at HealthPartners Institute and lead author on the study. “These findings show it’s a safe and effective alternative to in-person care for managing high blood pressure. The better we understand when telehealth is effective, the better we’ll be able to leverage it for those who want it.” 

The study started in 2017 at 21 HealthPartners clinics in Minnesota and western Wisconsin, and involved more than 3,000 patients with uncontrolled high blood pressure. 

Twelve clinics provided telehealth care. Patients would routinely monitor their blood pressure at home and have regular phone calls with a Medication Therapy Management pharmacist or nurse. Their virtual care teams would provide recommendations and modify medications as needed. 

Nine clinics provided in-person standard of care that included free follow-up blood pressure checks. 

For both groups, blood pressure decreased significantly during 12 months of follow-up from 157/92 to 139/82 mmHg in clinic-based care group and 157/91 to 139/81 mmHg in telehealth care patients. 

However, telehealth care patients were significantly more likely than clinic-based care patients to rate their care highly, and report that blood pressure care visits were convenient. 

In a 2020 study of 450 patients, researchers found that a group of blood pressure patients who had telehealth check-ins with pharmacists had substantially more blood pressure lowering and fewer cardiac events over five years than a group that received clinic-based care. 

The estimated costs for these cardiac events were $758,000 for the group of patients that received the telehealth intervention and $1,538,000 for the group of patients that received the standard care. 

“This latest data adds to existing research and makes the case for telehealth care among patients with high blood pressure,” Margolis said. “We’re consistently finding that for those who want it, it’s an effective approach to care and we should consider making it a more widely available option.”
