Healthcare today uses many digital tools like electronic health records (EHRs), scheduling systems, billing, and patient engagement software. Many healthcare providers use AI to help with tasks such as booking appointments, sending reminders, processing claims, and answering phone calls. But often, these AI tools come from different companies and use different technologies. This creates “agent silos” where AI systems cannot easily talk to each other.
When AI agents work alone, it is hard to make smooth workflows because they cannot share data or coordinate tasks. For example, a chatbot for scheduling might not talk to an AI that checks insurance. This separation means work gets done twice, responses get delayed, and chances to improve front-office work are missed. This causes inefficiency that can lower patient satisfaction, increase staff work, and raise costs.
Medical administrators and IT managers want AI systems to work well together. For practice owners, combined AI workflows can make the patient experience better by cutting wait times and improving communication.
IBM created the Agent Communication Protocol (ACP) with the BeeAI project to fix the problem of isolated AI agents. ACP is an open standard that lets AI agents from any vendor or system communicate and work together easily. It uses simple, vendor-neutral REST-based HTTP messaging for sharing data both asynchronously and synchronously.
ACP provides:
By setting a common communication method, ACP lowers the difficulty that stops multi-agent AI systems from working together across silos. It also helps IT teams solve many infrastructure and management challenges.
Google Cloud developed the Agent2Agent (A2A) protocol, another open standard that supports smooth communication between AI agents on over 50 platforms. These include companies like Salesforce, Deloitte, and ServiceNow. Like ACP, A2A focuses on AI systems working together well and offers:
Google’s Vertex AI Agent Builder also supports making custom AI agents and managing workflows using these protocols. It needs less than 100 lines of Python code. This appeals to healthcare IT staff who want flexible, easy-to-manage AI that can grow as needs change.
Most healthcare groups use a mix of EHR systems, practice management software, and automation tools from different providers. This makes integrating AI tough because each has its own way to communicate, different data forms, and security rules. Writing custom connections is expensive and hard to keep updated.
Open standards like ACP and A2A solve these problems by giving AI agents a shared language. Agents using these protocols can find and work with each other easily, no matter who built them or where they run. This helps healthcare leaders avoid constant custom coding and use ready-made interoperable solutions instead.
Healthcare in the U.S. follows strict rules like HIPAA to protect patient information. When AI systems share data, it is important that these rules are followed.
Both ACP and Google’s tools include built-in safety and compliance functions. ACP supports secure identity checks and task permissions so only allowed agents access sensitive patient data. Google’s Vertex AI uses filters, identity controls, and detailed logs to watch agent actions.
Using these standards lets healthcare organizations adopt AI that respects patient privacy and can be audited, while still allowing automation and teamwork.
AI automation in front-office work like booking appointments, checking insurance, patient check-in, and answering calls can ease staff workloads. AI agents trained for these jobs talk to patients and internal systems to work faster and more reliably than humans sometimes.
If AI agents work separately, problems appear such as:
Using interoperable AI agents with ACP or A2A lets healthcare make multi-agent workflows that act like a team but faster and more reliable. For example, a call can start with AI answering, then send the request to scheduling, verify insurance, and confirm the appointment—all automatically and properly.
Simbo AI, a company that focuses on front-office phone automation for healthcare, gains a lot from open communication standards. Its AI answers hundreds of patient calls daily and handles routine questions, booking, and reminders.
Using open protocols, Simbo AI connects with other healthcare AI systems to share patient data in real time, coordinate callbacks, and update schedules automatically. This gives patients a smooth experience and helps practice owners reduce busywork.
Google Cloud’s Vertex AI offers over 100 pre-made connectors and APIs managed by Apigee, an API platform. These connectors let AI agents securely access data from many healthcare systems such as:
Healthcare administrators use this to build workflows where agents access only authorized information. That way, AI answering services can check provider availability, insurance rules, and patient details directly.
Many AI systems cannot remember past interactions. This leads to asking patients the same questions again and an impersonal experience. Vertex AI’s Agent Engine supports both short-term and long-term memory. This lets AI agents remember conversations and user preferences during longer tasks.
This matters in healthcare where patients talk to many services. Combined AI agents can keep conversations smooth from phone to chatbots or appointment reminders. This helps patients and reduces stress for staff.
Keeping AI systems working well needs clear views into how they operate. Vertex AI gives tracing and visualization tools. IT staff can follow how AI agents make decisions, use tools, and interact.
These details help find problems, improve workflows, and make sure healthcare rules are followed. Simbo AI and healthcare IT teams can use performance data to improve AI agents and keep work safe and effective.
Open communication standards like ACP and A2A encourage healthcare organizations to use AI in more areas beyond front-office tasks. Some examples are:
Connecting many agents in and outside healthcare departments helps improve coordination and patient care without costly coding projects.
Healthcare in the U.S. has unique challenges with different provider networks, insurance systems, and strict privacy laws. AI systems that meet national standards like HIPAA and use open protocols such as ACP and A2A help simplify complex workflows.
Google’s location data covers over 250 million places daily and includes experimental geographic features for the U.S. This helps AI agents give local responses and assist front-office staff well. Practices in rural, city, or multi-state areas can use AI that fits their local provider schedules, insurance, and patient groups.
For practice managers and IT professionals in the U.S., using these open and secure AI agent systems offers a practical way to improve efficiency while following patient care and privacy rules.
Open communication standards like IBM’s Agent Communication Protocol and Google’s Agent2Agent protocol give healthcare providers in the United States a useful way to join different AI systems. These rules let AI agents work together safely and follow the law in many healthcare systems.
Using interoperable AI agents helps break down separated systems, cut paperwork, and improve front-office automation. Companies like Simbo AI, which works on phone answering and front-office AI, show how these tools help practice operations and patient care.
As healthcare keeps adding AI, knowing and using these open standards will be more important for administrators, IT managers, and practice owners who want AI solutions that work well together, are easy to manage, and can grow over time.
