Sutter Health is changing how it talks to its 3.5 million patients by using new computer programs called AI agents. This change comes because patients often have to wait too long to get simple questions answered or to book appointments. By working with companies like Hyro and Sierra, Sutter Health wants to make sure its staff can spend more time on hard medical cases while the AI handles the routine work. This rollout will affect roughly 13 million patient visits every year.
New Tools for Routine Healthcare Tasks
In September 2025, Sutter Health announced it would use Hyro’s technology across its entire system. These AI agents work through phone calls, text messages (SMS), and online chats to help people with basic needs.
Appointment Scheduling: Patients can book or change visits without waiting for a person to answer the phone.
Prescription Refills: The system helps process requests for medicine.
Billing Questions: AI answers common questions about money and insurance.
24/7 Availability: The service stays open even when the physical offices are closed.
"Sutter chose to adopt Hyro’s agents over other AI-powered patient communication tools because of the startup’s track record in this space." — Bollinger, Sutter Health Representative.
| Feature | Description |
|---|---|
| System Reach | Covers 13 million annual visits and 3.5 million patients. |
| Channels | Voice (phone), Chat (web), and SMS (text). |
| Main Goals | Reduce wait times and help staff focus on complex cases. |
| Governance | Managed by an internal AI council to ensure safety. |
Sutter Health is moving from human-only phone lines to a system where AI handles simple tasks first.

Methods of Safety and Control
Sutter Health uses an AI governance council to watch over these tools. This group works with Hyro to make sure the AI gives the right information and follows health laws. The goal is to make the technology "compassionate" so it does not feel cold or robotic to the person using it.
Real-time Reporting: Managers can see a dashboard that shows how the AI is performing right now.
Safety Checks: The council reviews how the AI talks to patients to prevent mistakes.
Data Use: The system looks for "actionable insights" to see where patients are having the most trouble.
Automation versus Human Care
Sutter Health says the AI is not meant to replace doctors or nurses. Instead, it is meant to "amplify empathy." There is a clear divide in the strategy:
The AI side: Handles fast, repetitive data like dates and refill numbers.
The Human side: Takes over when a patient has a complicated medical problem or an emotional need.
The Choice of Partners
Why did Sutter pick Hyro and talk with Sierra?
Hyro was chosen because it was already "production-ready," meaning it was ready to work in a real hospital immediately.
Sierra is working with Sutter to look at how AI can be measured by more than just how much money it saves, focusing instead on the patient's experience.
Technical Integration
The AI is not a separate app that patients must download. It is built directly into Sutter’s current systems. This means if a patient texts the hospital, they are talking to the AI agent immediately.
Measuring Success Beyond Cost
Experts at the HLTH 2025 conference noted that healthcare groups are looking for ways to use AI "responsibly and at scale." Sutter Health and Sierra held a "Fireside Chat" in October 2025 to discuss these points.

"AI agents can help healthcare organizations cut costs, reduce administrative workload, and improve patient and member experiences." — Sierra Official Statement.
The analysis suggests that the primary "signal" for success is not just speed, but whether the AI makes the patient feel cared for. However, because these tools are new, it is still unclear if patients will prefer talking to a computer or if they will eventually find the lack of a human voice frustrating for specific billing or scheduling errors.
Findings and Next Steps
The evidence shows that Sutter Health has fully committed to AI as a way to manage its high volume of patients.
System Deployment: The AI is active across voice, chat, and SMS channels.
Operational Shift: Customer service teams are being retrained to handle only "complex cases" while the AI manages the rest.
Uncertainty: It is not yet known how the system will handle rare or very confusing patient requests that do not fit into the AI's "routine" programming.
The next steps for the organization include monitoring the AI governance council reports to see if the AI performance meets the "compassionate caregiver" standards set by the leadership.
