High blood pressure is a major cause of heart disease and stroke, which are leading causes of death in the United States. To manage it well, people need to check their blood pressure regularly to keep it in a safe range. Medicare Advantage plans and programs like HEDIS look at how well blood pressure is controlled. These ratings can affect how much money healthcare providers get paid and extra rewards they may receive.
Good management of high blood pressure often needs people to reach out to patients. Nurses usually call patients to check if they are taking their medicine, record their blood pressure numbers, look for symptoms, and see who might be at risk. But making all these calls takes a lot of time and money, which can limit how often and how many patients can be contacted.
A recent study from the American Heart Association’s 2025 meeting looked at using AI voice agents for checking blood pressure. The study included 2,000 adults, mostly 65 years or older. The AI voice agents called patients in different languages and asked them to say their blood pressure numbers. The numbers could come from their home devices or the call itself. If the AI detected very high or low numbers, or serious symptoms like dizziness or chest pain, it alerted nurses or medical assistants right away.
These results give healthcare leaders useful data to rethink how they contact patients.
Chronic disease care costs a lot in the U.S., and remote monitoring is part of that. Healthcare groups, especially those paid for good results, need to balance cost and quality carefully when reaching out to patients.
Using AI voice agents helps not just by cutting costs but also by improving quality scores that affect payment levels from Medicare Advantage programs.
Medical practice managers and owners see important effects from using AI voice agents on how they use their staff and money.
Using AI voice agents in checking blood pressure shows how automating tasks can improve clinical work. Automation can save time, lower mistakes, and keep patients involved consistently.
Healthcare IT teams can add AI tools to current systems so the automation supports work without causing problems.
The study shows that AI voice agents save money and help get more patients involved. They also improve quality scores and health results. For healthcare groups in the U.S., especially those with many older patients with high blood pressure, this tech offers a way to better use money and staff.
By lowering costs and boosting performance on quality ratings, AI voice agents can help providers meet their financial and health goals. Using AI for remote blood pressure checks is a practical change that may improve how medical offices work all over the country.
The AI voice agents aim to engage patients, particularly older adults, in self-reporting accurate blood pressure readings remotely, identify patients needing follow-up care based on these readings, and escalate urgent cases to licensed healthcare professionals, improving care management and reducing clinician workload.
Calls are escalated if blood pressure readings fall outside a specified threshold, adjusted for conditions like diabetes, or if the patient reports serious symptoms such as dizziness, blurred vision, or chest pain; urgent cases receive immediate escalation, while non-urgent issues are escalated within 24 hours.
The study included 2,000 adults, with a majority aged 65 and older (average age 72, 61% women), all receiving care for hypertension, focusing on improving blood pressure monitoring and management through AI interventions.
The integration of AI voice agents led to an 88.7% reduction in cost-per-reading compared to using human nurses, significantly lowering manual workload and healthcare costs while maintaining effective patient engagement and data collection.
AI voice agents successfully contacted 85% of targeted patients, with 67% completing the call and 60% providing compliant blood pressure readings during the interaction, demonstrating high patient engagement and data acquisition rates.
The study noted a 17% increase in controlling blood pressure (CBP) Stars performance, moving from a 1-star to a 4-star rating in Medicare Advantage and HEDIS measures, indicating improved patient outcomes and care quality.
Patients rated their satisfaction on a 1-10 scale after each call, with average scores exceeding 9, indicating an excellent experience and high acceptance of AI voice agents for managing blood pressure remotely.
Limitations include the observational, retrospective study design without a control group, lack of direct comparison between AI and human calls, and reliance on existing data without prospective randomization, which could impact the generalizability of results.
Readings collected by AI agents are entered into the electronic health record (EHR), reviewed by clinicians, and used for clinical decision-making, including referrals to care management teams for patients with uncontrolled hypertension.
The CMS Star Ratings (MA Stars) incentivize healthcare providers by awarding ratings from 1 to 5 stars based on quality metrics, including blood pressure control; improvement from 1-star to 4-star through AI interventions enables providers to qualify for bonus payments and reflects enhanced care quality.
