Mar 15, 2025

Executive Summary

Healthcare's next evolution lies in systems that think, adapt, and act. Traditional software has powered critical systems for decades, but AI agents represent a paradigm shift transforming passive tools into active partners. Unlike static programs, AI agents work autonomously, learn continuously, and act proactively. For technical leaders in healthcare, understanding this shift isn't just about technology it's about reimagining patient care, operational efficiency, and decision making. In this article, I explore how AI agents differ from traditional software and why they matter in the future of healthcare innovation.

Grounding AI Agents in Reality

In my 31 years working at the intersection of AI, healthcare IT, and software engineering, I've seen firsthand how technology has evolved—from static, rule based systems to adaptive, intelligent AI agents that practically think for themselves. But with all the hype around AI, one question keeps coming up.

"What's the real difference between AI agents and the software we've been using for decades?"

At first glance, both automate tasks and improve efficiency. But the real distinction lies in how they operate, learn, and respond. Traditional software follows a set of rules it does what it's programmed to do, nothing more. AI agents, on the other hand, bring semantic capabilities combined with autonomy, continuous learning, and proactivity into the equation.

For healthcare leaders and IT teams stretched thin, this isn't just a technical upgrade it's a fundamental shift in developing software and integrating hospital systems.

The Traditional Software Approach

For decades, healthcare has relied on traditional software code designed to follow predefined rules, execute specific tasks, and provide structured outputs based on hardcoded logic. These applications have been essential in digitizing healthcare operations, from EHR systems and scheduling platforms to billing software and ERP systems.

But here's the catch: Traditional software is declarative. It operates exactly as programmed, no more, no less.

Take EMR systems as an example. They're highly structured, allowing clinicians to efficiently input, store, and retrieve patient data. However, if workflow inefficiencies arise—for example, physicians spending too much time on documentation—the software doesn't recognize the problem or suggest a fix. Instead, IT teams must intervene, analyze usage patterns, manually adjust settings, update rules, or integrate third-party solutions to improve performance.

The same goes for hospital scheduling systems—they efficiently manage appointments but don't proactively adjust for canceled visits, staff shortages, or unexpected patient surges unless someone manually reconfigures the parameters.

Traditional software is reactive, not proactive. It waits for inputs and requires constant human oversight to adapt to changes. This model worked well when processes were predictable, but in today's fast-paced, data-driven healthcare environment, it's becoming a bottleneck. This is where AI agents come in.

The AI Agents Approach

Bill Gates predicted in 2023

that "the real shift will come when agents can help patients do basic triage, get advice about how to deal with health problems, and decide whether they need to seek treatment." In 2025, this prediction will become a reality as AI agents transform healthcare delivery.

Unlike traditional software, AI agents don't just execute commands they think, adapt, and improve over time. Instead of waiting for human input to adjust workflows, AI agents operate independently, continuously learning from data and proactively solving problems before they escalate.

The biggest shift? Autonomy combined with semantic capabilities. Traditional systems rely on humans to adjust, but AI agents can assess real-time conditions and act accordingly using code reasoning. The agents determine what software code to call at runtime. Take automated triaging as an example: instead of simply flagging patients based on predefined rules, an AI agent can dynamically adjust risk scores, optimize patient flow, and prioritize cases based on continuously updated clinical data—all without needing a human to tweak the parameters manually.

Another critical advantage is continuous learning. Traditional systems remain static until updated, but AI agents refine their models when they process new data. In healthcare, this means an AI-powered diagnostic tool doesn't just assist with decision-making—it gets better over time, recognizing nuanced patterns that weren't apparent in previous data. Once limited to historical trends, predictive analytics can now evolve in real-time, improving accuracy in everything from disease detection to operational forecasting.

A valuable trait of AI agents is proactivity. Traditional software flags an issue; AI agents solve it or alert the right people before it becomes problematic. Instead of a system simply logging that a hospital is exceeding ICU capacity, an AI agent can anticipate bottlenecks, reroute admissions, and suggest staff reallocations before the system gets overwhelmed. Similarly, AI-driven monitoring tools can predict when a critical piece of equipment is likely to fail, reducing downtime and avoiding last-minute disruptions.

This shift from static to dynamic, reactive to proactive, manual to autonomous is what makes AI agents a game changer for healthcare IT. Instead of just making systems run, they make them think, alleviating the burden on already overextended teams and ensuring that decisions are faster, smarter, and more efficient.

Technical Insights: How LLMs Orchestrate Functions in AI Agents

At the core of an AI agent's autonomy, semantic capabilities, learning, and proactivity is a large language model (LLM) that serves as the reasoning engine for orchestrating functions. Unlike traditional rule based automation, or declarative programming which executes predefined code defined by a programmer or business analyst, an LLM powered agent can interpret complex inputs, generate structured outputs, and dynamically adapt its responses based on real time context.

1. Understanding the Role of the LLM in Orchestration

An LLM acts as the decision-making layer in an AI agent, sitting between input sources (data streams, user interactions, system logs) and executive functions (API calls, workflow automation, alerts). Instead of executing a fixed set of commands, the LLM determines:

1. What needs to be done (task inference)

2. How it should be done (decision logic generation

3. Who or what should be involved (orchestration

4. Software logic. What functions should be executed?

For example, in a hospital operations setting, an AI agent using an LLM can:

1. Ingest real-time patient flow data from an EHR.

2. Recognize patterns suggesting emerging bed shortages in the ICU.

3. Synthesize relevant information and generate context-aware recommendations to reallocate beds, alert staff, or adjust elective surgery schedules.

4. Trigger a semantic aware software function or an automated workflow that integrates with Microsoft Teams, sending real-time alerts to hospital administrators and care teams.

How Semantic Capabilities Transform AI Agents

Semantic capabilities lie at the core of modern AI agents, serving as the cognitive engine that empowers their understanding, reasoning, and decision making. Unlike traditional software, which is limited to processing functions we declare in advance, keywords, or rigid rules, semantic enabled agents can interpret the nuances of human language, discern context, and respond meaningfully, marking a significant evolution in artificial intelligence. This allows the AI to use semantic matching to determine which code to run.

At the heart of semantic AI lies a powerful semantic engine, typically built upon advanced large language models (LLMs), such as o3 mini or DeepSeek. These models provide critical reasoning, planning, and reflective abilities. AI agents achieve a nuanced understanding of complex contexts through these capabilities, enabling them to engage with users and tasks at a profoundly deeper level.

Another keystone is the agent's capability for reasoning and planning. With semantic comprehension, AI agents can intelligently break down intricate tasks into logical steps, forming dynamic plans that adapt fluidly to changing circumstances. This adaptive planning is crucial for handling real world complexity, making semantic agents reliable collaborators in various domains.

Frameworks like Microsoft's Semantic Kernel effectively demonstrate the practical application of these semantic capabilities through specific implementations. Native functions, for instance, extend an agent's abilities by connecting it to external systems or databases, enabling actions that the language model alone couldn't perform.

Plugins further enrich these capabilities, combining with personas, planners, and memory to create versatile assistants capable of automating sophisticated tasks. Moreover, semantic agents utilize various tools intelligently, deciding autonomously when and how to engage external resources to accomplish complex goals.

What AI Can—and Cannot—Fix in Hospitals today

The Harsh Reality: IT and Operations Are Overwhelmed

Hospitals are running on fumes. Staff shortages, shrinking reimbursements, and shifting regulatory demands have leaders constantly putting out fires instead of driving real innovation. IT and operations teams are stretched so thin that just keeping the lights on feels like a win. There's no room for bold technology projects when every day is about survival.

This is precisely where AI agents can help—not as a replacement but as factual support. Think of them as extra hands on deck, picking up the administrative load that drains time and energy. They can optimize scheduling, flag billing inconsistencies, and streamline workflows in ways that don't require another massive system overhaul. Small, targeted implementations can start making an impact almost immediately, freeing up your teams to focus on what matters—patient care, strategy, and solving the more significant problems that no AI can fix.

Identifying the Right AI Use Cases for Immediate Impact

Not every hospital process is a good fit for AI; trying to overhaul everything at once is a guaranteed way to fail. The key is to start where AI can deliver quick, meaningful wins—places where manual effort slows things down, errors are costly, and automation can step in without disrupting patient care.

One of the most significant opportunities is scheduling and workflow automation. AI agents can help coordinate appointments, optimize resource allocation, and adjust staffing based on real-time demand, reducing bottlenecks and improving efficiency without requiring constant manual intervention.

Another high-impact area is billing and revenue cycle management. AI can spot coding errors, flag potential claim denials before submission, and streamline reimbursement workflows, cutting down on costly delays and administrative backlogs.

The goal isn't to replace human or physician decision-making—it's to clear the roadblocks that slow your teams down. Start with these focused, high-impact areas, and you'll see how even small AI-driven improvements can make an outsized difference.

AI Agents as Practical Support, Not Just Digital Snake Oil

Okay, so after all of this, it is worth summarizing and closing with AI in healthcare is not digital snake oil. And It isn't about chasing trends or replacing human expertise—it's about practical, meaningful support where needed most. The reality is that hospitals and IT teams are running at capacity, constantly balancing staffing shortages, operational bottlenecks, and an ever growing administrative burden. The promise of AI agents isn't in grand, sweeping transformations—it's in targeted, measurable improvements that alleviate pressure and allow people to focus on what matters.

If we strip away the buzzwords, we're really talking about better workflow orchestration, more proactive systems, and technology that doesn't just wait for input but actively solves problems. Whether it's optimizing scheduling, reducing documentation burdens, or flagging reimbursement risks before they become revenue leaks, AI agents can be force multipliers for overextended teams.

In closing, let's focus on real impact over hype, small wins over sweeping changes, and using AI not as a disruptor but as a practical partner in making healthcare work better for everyone.
