Metro area public health and health care experts conceived and created this groundbreaking tool in 2011 to provide location-based information on population health measures in the metro Denver area. CHORDS expanded to Larimer and Weld counties in 2018.

CHORDS aggregates medical and behavioral health data from 14 contributing providers. The information does not identify patients and does not include protected health records. It is meant to pinpoint pressing health needs in a community and suggest potential responses.

CHORDS partners providing technical support include University of Colorado Denver Adult and Child Consortium for Outcomes Research and Delivery Science (ACCORDS), Colorado Community Managed Care Network (CCMCN), and CORHIO.

The CHORDS network is also a participant in the Childhood Obesity Data Initiative (CODI@CHORDS). This project, funded by the Centers for Disease Control and Prevention, facilitates access to integrated multi-sector data from pediatric care and weight management programs based in clinical or community settings. The project seeks to build data capacity for research that assesses strategies to prevent and treat childhood obesity. Community data partners participating in CODI@CHORDS include Girls on the Run and Hunger Free Colorado.
