CHORDS Data Provide Unique Lens To Assess Depression In Denver

There has been surprisingly little evaluation that looks comprehensively at who’s affected by depression in Denver and what the Mile High City is doing – and can do – to address it. Data from CHORDS helped offer new insights into depression diagnoses throughout the city: Read the story.

The numbers are now one click away, whether you are comparing the number of adolescents diagnosed with depression in Frederick or tracking tobacco use in Denver’s Capitol Hill neighborhood.

The Colorado Health Observation Regional Data Service (CHORDS) is a unique regional network of health care, public health, and behavioral health partners that uses electronic health record data to identify health trends and support public health evaluation and monitoring efforts.

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 11 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.

Since 2016, the Colorado Health Foundation has provided grant support to the Colorado Health Institute (CHI) to expand the number of public health agencies using CHORDS to include the entire Denver metropolitan area and recruit additional health care and mental health providers to contribute data.

CHORDS data contributors:

Barbara Davis Center for Diabetes, Children’s Hospital Colorado, Clinica Family Health, Clinica Tepeyac, Colorado Coalition for the Homeless, Denver Health, High Plains Community Health Center, Jefferson Center for Mental Health, Kaiser Permanente Colorado, Mental Health Center of Denver, Mental Health Partners, North Colorado Health Alliance, STRIDE Community Health Center, and Salud Family Health Centers.
