WHO WE ARE AND WHAT WE DO

Helping you understand the health status of individual patients, subgroups and whole populations.

The Johns Hopkins ACG System models and predicts an individual’s health over time using existing data from medical claims, electronic medical records, and demographics like age and gender.

You gain the insights you need to evaluate and compensate providers, stratify risk, identify patients who would benefit from care management and forecast health care utilization.

THE ACG SYSTEM ADVANTAGE

For more than 30 years Johns Hopkins statisticians, economists and health care providers have collaborated with users to continually improve the ACG System’s ability to describe population health.

Over 140 million lives are impacted by the ACG System worldwide as health systems, health organizations, insurance companies, accountable care organizations (ACOs) as well as individual clinics and clinicians rely on the ACG System for health care analytics and insights into population health.

From the beginning, the ACG System has provided a more accurate representation of the health of the general population by transforming health care data into actionable information.

APPLICATIONS

By capturing the morbidity burden of populations, the Johns Hopkins ACG System helps explain and predict how health care resources are delivered and consumed. Click on below categories to explore these different application types in detail, or visit our Applications page to see more application types.

Pharmacy AnalysisFinancial Analysis

Understand the health care needs of a population or subgroup. By taking into account the differences in illness burden among different patient populations, the ACG System helps you determine variations in disease prevalence as well as resource use.

Disease Management | Case ManagementCare Density | Care Coordination | Coordination Markers |

Optimize your case management and disease management programs. With the ACG System you can identify up to 25% more individuals for care management before they become high utilizers.

LEARN MORE

Program Evaluation | Provider Profiling (not mentioned)

Evaluate your provider network and individual providers. The ACG System uses a holistic approach to profile and evaluate your provider; examining health care expenses, practice patterns and the aggregate health of patient panels.

Resource Allocation | Capitation | Underwriting | Risk Adjustment (not mentioned)| Payment Adjustment (not mentioned)

You can use the ACG System to establish capitation rates, reimbursement rates and insurance premiums. You can also use it to allocate resources within a health system to appropriately target populations in greatest need.

MEASURING POPULATION HEALTH WITH THE ACG SYSTEM TO SUPPORT THE “TRIPLE AIM”

HealthPartners, the largest consumer-governed, nonprofit health care organization in the United States, used the ACG System to develop summary measures to identify and address conditions and factors that have the greatest impact on population health. The method addresses a persistent need in population health measurement for improvement. The article is a joint publication initiative between Preventing Chronic Disease and the National Academy of Medicine.

PROACTIVE CARE MANAGEMENT

ARTICLE: High-Risk Case Identification for Use in
Comprehensive Complex Care Management

The ACG System was used to accurately select multi-morbid patients for participation in proactive care management, even after some of the highest risk patients are excluded because of prior clinical considerations.
