High blood pressure is a common health problem. It increases the risk of heart attack, stroke, and other serious illnesses. Checking blood pressure often and accurately is very important, especially for older adults and women after childbirth. Studies show that older adults may have trouble reporting their blood pressure correctly because of mobility problems, memory issues, or language differences. Women who have high blood pressure after giving birth need close watching in the first weeks to avoid hospital visits and heart problems.
Usually, nurses call patients to remind them to check their blood pressure and to gather their readings. They also ask about any symptoms. This way helps take care of patients but has problems like heavy workloads for nurses, patients not always answering, and high costs. AI voice agent technology offers a new way that could be cheaper and easier to use on a larger scale.
AI voice agents use technology to talk with patients automatically on the phone. These systems call patients and ask for their latest blood pressure numbers. They also check if patients feel dizzy, see blurry, or have chest pain, which might need quick attention. If a patient says their blood pressure is too high or they feel bad, the AI passes the call to a nurse or medical assistant.
A recent study shown at the American Heart Association meeting in 2025 tested this system with 2,000 mainly older adults with high blood pressure. The AI spoke English and Spanish to help reach more people. The blood pressure numbers were sent straight to doctors’ electronic records so they could review and act fast.
These numbers show that many patients responded well and got involved. Patient satisfaction with AI calls averaged more than 9 out of 10. This shows many patients, even older ones, accepted the automated calls.
Tina-Ann Kerr Thompson, M.D., the lead researcher, said she was surprised by the high satisfaction. Before, people thought patients might not like talking to AI. She said that getting patients involved and collecting timely data helps improve heart health.
AI calls help older adults, but women who just had babies and have high blood pressure need special care too. Nurse practitioners (NPs) have tried remote patient monitoring (RPM) after childbirth. They check blood pressure from a distance, watch for problems, and step in when needed.
A pilot study by UCLA and Cedars-Sinai showed this NP monitoring had high patient following (91.23%) and satisfaction (92%). The nurse checked patients’ blood pressure without in-person visits and helped reduce trips to the hospital.
This method is safe and saves money. High blood pressure causes 2.5% to 4.6% of hospital returns within six weeks after birth. Remote monitoring helps with issues like transportation, appointment timing, and health differences among groups.
Using AI voice agents to check blood pressure saves a lot of money. In the Emory Healthcare study, the cost for each blood pressure reading went down by almost 89% when using AI calls instead of nurse calls. This is because AI costs less in staff time and can call many people fast.
Lowering nurse workload is important. Nurses then have more time for tough cases instead of making reminder calls. Also, better call completion and accurate readings help meet health quality standards like Medicare and HEDIS. AI improved these ratings from 1-Star to 4-Star, a 17% rise that affects payments and bonuses.
Healthcare managers and IT leaders can redesign their work, reduce staff stress, and cut costs while keeping or improving patient results.
Using AI for routine patient calls helps healthcare teams do less manual work without lowering care quality. AI mixes well with electronic health records (EHR) systems to capture data and support quick decisions.
In U.S. healthcare, AI matches with care models that want better patient involvement, quality improvements, and cost control. Staffing shortages and rising costs make AI automation an option worth thinking about.
Even with these challenges, studies show patients accept AI and that it helps operations. The future of outpatient care will likely include more AI-supported models.
As healthcare deals with more patients and harder cases, AI tools like Simbo AI’s phone automation help manage patient calls efficiently. These tools assist in routine checks like blood pressure, support nurse monitoring plans, and save costs while keeping good care. Healthcare leaders and IT staff in the U.S. need to learn about and use these tools to meet current healthcare demands.
AI voice agents prompt and engage older adults to self-report accurate blood pressure readings during calls. These conversational agents use natural language processing to facilitate live or recent readings, improving the accuracy and completion rates of home blood pressure monitoring compared to traditional phone calls with healthcare professionals.
The study involved 2,000 adults, predominantly aged 65 or older (average age 72), with 61% women. All participants were receiving care for high blood pressure and were identified through electronic health records as having gaps in blood pressure data or uncontrolled readings.
The AI voice agent escalates calls to a licensed nurse or medical assistant if readings fall outside individualized threshold ranges or if symptoms like dizziness, blurred vision, or chest pain are reported. Escalations occur immediately in urgent cases or within 24 hours for non-urgent concerns.
The AI voice agent communicated with patients in multiple languages, including English and Spanish, ensuring accessibility and engagement across diverse patient populations.
Readings collected via AI calls were entered into the electronic health record (EHR), reviewed by clinicians, and triggered referrals for care management if blood pressure was poorly controlled. This integration reduced manual clinician workload and improved data-driven patient management.
The AI voice agent deployment resulted in an 88.7% reduction in cost per blood pressure reading obtained compared to calls made by human nurses, making the AI solution significantly more cost-effective while maintaining quality outcomes.
Among completed calls, patients reported a high satisfaction rate exceeding 9 out of 10, indicating excellent acceptance of the AI voice agent experience in managing their blood pressure remotely.
The AI intervention closed 1,939 controlling blood pressure (CBP) gaps, improving performance from a 1-Star to a 4-Star rating on Medicare Advantage and HEDIS quality metrics, reflecting a 17% improvement and eligibility for bonus payments.
Limitations included an observational design without a control group, lack of comparison to human-only calls due to feasibility constraints, and retrospective evaluation of existing data, making findings preliminary prior to peer-reviewed publication.
AI voice agents enable remote, scalable outreach to patients with limited access to care, facilitating timely self-monitoring, symptom reporting, and clinical escalation. This helps overcome challenges in patient support, improves blood pressure control, and enhances quality outcomes in preventive care.
