High blood pressure, or hypertension, is an important health issue in the United States. It mostly affects people aged 65 and older. Controlling hypertension helps prevent serious problems like stroke, heart attacks, and kidney disease. Checking blood pressure accurately, following up on results quickly, and involving patients in their care are important for managing chronic diseases well.
A recent study shared at the American Heart Association’s Hypertension Scientific Sessions in 2025 showed results from AI voice agents monitoring blood pressure. The study, led by Dr. Tina-Ann Kerr Thompson at Emory Healthcare, involved 2,000 adults, mostly over age 65, with an average age of 72. Most were women (61%). The AI system made calls in several languages, asking patients to report their blood pressure or give live readings. If the readings were unusual or patients said they felt dizzy or had chest pain, the system quickly alerted nurses or medical assistants within 24 hours. This data was linked to Electronic Health Records (EHR) to help doctors respond faster.
The AI system reached 85% of patients, and 67% of those answered the calls. Out of those, 60% gave blood pressure readings that doctors could use. These efforts helped close 1,939 gaps in care related to blood pressure control. Because of this, Medicare Advantage and HEDIS ratings improved from a low 1-Star to 4-Stars. This meant a 17% boost in scores for controlling blood pressure, which is important for financial rewards and the reputation of healthcare providers.
Using AI voice agents lowered the cost per blood pressure reading by 88.7% compared to usual nurse phone calls. Most of this cost saving happened because automated calls replaced many manual calls by healthcare staff. Since many healthcare providers face limited resources and staff shortages, AI helps them stay in contact with patients more easily and in less time.
Clinically, the AI system immediately escalated urgent cases to make sure patients with serious symptoms or dangerous blood pressure numbers got quick care. Less urgent but still abnormal results were checked within a day. This helped close care gaps that could have worsened if left untreated.
Data from AI calls was added to EHRs so doctors could watch blood pressure trends. This helped providers make better care decisions and customize treatment plans. Collecting this data also matched reporting needs for programs like HEDIS and Medicare Star Ratings, which reward good chronic disease care and prevention.
Medicare Star Ratings and HEDIS are common ways to judge healthcare quality. Star Ratings go from 1 to 5 stars and look at health results, patient satisfaction, and how well care is coordinated. These ratings affect payment levels and bonuses under value-based care contracts.
The recent study showed that AI-driven blood pressure monitoring raised Medicare Advantage Star Ratings from 1-Star to 4-Stars for blood pressure control. This improvement can bring in big financial bonuses, with each star increase potentially adding millions in payments to healthcare plans. A better rating also helps attract and keep patients.
HEDIS, run by the National Committee for Quality Assurance (NCQA), uses standard measures to check clinical quality, including blood pressure control and chronic disease care. AI tools help close gaps found in HEDIS reports by encouraging patients to follow treatments and meet clinical goals. For example, AI combined with data analysis can spot patients at risk of not taking their medicine, so providers can give extra help.
Besides patient calls, AI-powered predictive analytics helps improve preventive care and chronic disease management. Health systems and Accountable Care Organizations (ACOs) use these models to group patients by risk, predict health events, and use resources better.
These models can tell which patients might have uncontrolled hypertension, skip treatments, or miss screenings. This helps care managers focus on those who need the most attention. Groups like Kaiser Permanente and Mission Health Partners saw better quality scores and fewer avoidable hospital visits by using data-driven approaches.
Predictive tools also offer detailed reports and real-time alerts. These help healthcare teams act before a patient’s condition gets worse, lower unnecessary doctor visits, and improve health results. Better results help improve Medicare Star Ratings and HEDIS scores.
Optimizing Workflows with AI-Enabled Communication Systems
AI voice technology and automation are changing how front offices in medical offices manage patient calls and workflows. Simbo AI’s solutions show how AI can take over tasks like reminding patients of appointments, collecting patient information, and making calls for blood pressure checks.
Automating these calls lets staff spend time on more important work like patient care and follow-ups. AI voice agents handle many calls, speak multiple languages, and work well with diverse patients across the U.S. They collect health data, remind patients to check blood pressure, and flag unusual readings for human review.
When AI calls link directly to EHRs, the information flows smoothly. Providers get accurate, usable data without extra manual work, which improves record-keeping. AI systems also quickly alert staff about urgent cases, making care safer and faster.
Automation lowers the workload for clinicians and provides cost benefits. Practices can run better, save money on overtime, and reduce staff burnout. From the IT side, linking AI with existing systems helps organizations grow and keep their work efficient for the long term.
The Emory Healthcare study found high patient satisfaction with AI voice calls. Patients gave an average score above 9 out of 10. This shows many older adults are comfortable with automated health calls, going against the idea that older people avoid technology in healthcare.
AI systems provide quick follow-up or escalation if blood pressure is abnormal or if serious symptoms happen. This helps patients feel safe because they know health concerns will be addressed quickly by professionals. Combining AI with human care builds patient trust and keeps them involved, which is key to good chronic disease management.
Providers noted that patients using AI voice calls reported blood pressure more often and more accurately. This data helps doctors make better care choices and improves health outcomes.
Medical practice leaders face pressure to improve clinical quality while controlling costs and operations. Using AI for blood pressure monitoring can help close care gaps and improve Star Ratings and HEDIS scores. This affects payments and how well a practice competes.
IT managers play a big role in making sure AI tools work well with existing health record systems and communication setups. Data privacy, rules, and staff training are important for success. The ability of AI to speak different languages also helps serve diverse patient groups.
Automating routine patient outreach frees up staff to focus on patient care and complex decisions. The cost savings and better workflow contribute to running the practice smoothly over time.
In short, AI-driven blood pressure monitoring combined with data analysis and automation can help medical practices in the U.S. manage hypertension better, improve ratings, cut costs, and raise patient satisfaction.
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.
