CIIS data requests
When doing legitimate research on the treatment, control, investigation and prevention of diseases and conditions dangerous to public health, researchers or specifically authorized persons may need to obtain potentially identifying data from confidential records held by the Colorado Immunization Information System. We may provide access to potentially identifying information if specific conditions are met. If you are conducting research and wish to request data from us, please complete the CIIS Data Request Form. Additional documentation, including data use agreements, may be necessary depending on your request.
The Healthcare Effectiveness Data and Information Set (HEDIS) is used by more than 90 percent of America's health plans to measure performance on important dimensions of care and service, including the delivery of vaccines. We can provide HEDIS matches for health plans if they have a signed Letter of Agreement and submit data to CIIS on at least a monthly basis. If you’re working for a health plan interested in a HEDIS match, please follow the steps included in the HEDIS Data Request Process document.
