ACO Success Depends on Accurate
Patient Population Definitions

Accountable Care Organizations
(ACOs) must precisely pinpoint
patient populations to understand
the risk to customize solutions.

How ACOs Use Population
Definitions
3
ACOs define populations for four main reasons
To identify their members and attribute those patients
to the correct physician(s)
To attribute the right patient to the right physician for
pay-for-performance incentives
To accurately report CMS and other quality measures
To perform population health analytics that enable
providers to effectively manage each patient’s health

Challenges to Defining an ACO
Populations
4
ACOs identify high-risk members and manage their
health more carefully by:
• Performing analytics to predict likelihood of specific events
• Tracking utilization trends across the full care continuum
• Monitoring quality of care by facility and by provider.

Defining High Risk Populations

Key challenges in defining ACO
populations.
• Multiple providers per patient
• Multiple data sources
• Reconciling multiple identifiers for

Clinical Integration Hierarchy
6
Health Catalyst recommends using a clinical hierarchy system for
grouping these common clinical characteristics and identifying
individuals who share these characteristics.
Starting at the most-general and moving to the most-granular level,
this hierarchy is as follows:
1: Clinical program:
Twelve clinical programs make up a comprehensive healthcare
delivery system.

Using Technology to Build and
Refine Registries
Health Catalyst has developed two main tools to easily, efficiently, and
accurately define patient populations. These analytics applications run
on top of our enterprise data warehouse platform.
8
Population Explorer
Delivers a “starter set” of more
than 1,000 different registries.
It begins with standardized
rules for creating the registry
Then adds care mappings to
bring additional data elements
(like laboratory results) into
the registry to create a more
comprehensive rule for
defining the population.
Cohort Builder
This analytics application
enables more sophisticated
definitions of a population.
Teams of clinicians, analysts,
and others work together using
this tool to adjust and refine
the population definition to suit
the ACO’s specific needs.
The level of refinement brought by these tools defines the ACO’s
effectiveness and goes beyond the diagnosis codes to pick up those
patients who might otherwise be missed.

Summary

Using EDW analysis tools mapped to a deep clinical integration
hierarchy allows ACOs to develop the precise, detailed population
definitions, and vastly improve quality and accuracy.
