Ambulatory Care Groups; An Evaluation for Military Health Care Use
Abstract
The Ambulatory Care Evaluation Study (ACES) team, part of the U.S. Army Health Care Studies and Clinical Investigation Activity, evaluated the Ambulatory Care Groups (ACGs) System developed at Johns Hopkins University for possible military use. The ACGs are unique in that they were developed to categorize patients or populations rather than visits or services. The ACGs categorize diagnoses according to their likelihood of persistence. They are conceptually simple and require only patient age, gender and ICD-9-CM diagnoses over the period of time under study. The ACGs are based on 34 broad clusters of ICD-9-CM diagnoses called ambulatory diagnostic groups (ADGs). The ACGs were developed from enrolled population data during a one-year time period. The ACG developers made three specific claims about the ACG grouper performance: First, 30-50% of the variance in number of visits and ambulatory charges can be explained by the ACG designation.
