In an era where health care organizations face mounting pressures to improve patient outcomes, reduce costs, and address disparities, population health management has emerged as a critical focus. But achieving meaningful change requires more than just good intentions — it demands data-driven solutions that translate insights into action. That’s where the Johns Hopkins ACG^® System comes in. As a foundational tool for health care data analytics companies, the ACG System serves as a “core component” model, seamlessly integrating into the products of leading analytics companies to help hospitals, health systems, payers and others tackle the biggest challenges in population health.

What is the ACG System?

The ACG System is a globally recognized risk adjustment and predictive modeling software developed by the Johns Hopkins Bloomberg School of Public Health. By analyzing comprehensive health care data — including diagnoses, pharmacy claims and demographic details — the System provides actionable insights into patient populations. It helps identify high-risk individuals, optimize resource allocation and improve care coordination. While many health care organizations use the ACG System directly, its impact is amplified through collaborations with data analytics companies that embed its functionality into their products.

Why the “Core Component” Model Works

The ACG System’s integration into analytics platforms underscores its flexibility and scalability. Rather than reinventing the wheel, analytics companies leverage the proven methodologies of the ACG System to enhance their own solutions. This collaborative model accelerates innovation, enabling faster deployment of tools that make a real difference for patients and providers.

Up Next: Use Cases

In our next post, we’ll take a closer look at how the ACG System serves as a foundation for existing health care analytics solutions. Through detailed use cases, we’ll illustrate why the ACG System is an essential tool for integrators. Key themes we’ll explore include:

• Maximizing Data Utility: Keeping up with the growing demand for advanced analytics and population health use cases.
• Driving Targeted Interventions: Enhancing efficiency and improving outcomes through more precise, data-driven decision-making.

The Future of Collaboration

As health care data becomes increasingly complex, the need for advanced analytics will only grow. The Johns Hopkins ACG System remains committed to fostering partnerships with analytics companies to address emerging challenges in population health. Together, these collaborations ensure that health care organizations have the insights they need to deliver better care, control costs and promote health equity.
