Data Delivery Services

Message from Compass: 

Like many other organizations, Health Data Compass experienced significant turnover in the last year and lost many of our resources. As a result, our data request queue continues to grow and is resulting in large delays with data delivery. To reduce the queue, Compass is hiring, training, and optimizing processes, though due to the depth of the queue, we continue to anticipate large delays through the first half of 2023. 

Self-Service Deidentified Cohort Queries

Our self-service applications are available to employees of Compass's partners and are ideally suited for high-level data exploration and feasibility analyses. Apply for access via our De-identified Data Access Agreement.

Leaf Application

Health Data Compass enables access to UCHealth patient data in a fully deidentified, aggregated form via the Leaf Web Application.  Leaf allows users to identify inclusion and exclusion criteria from various data elements collected in UCHealth's Epic medical record system, including temporal relationships. Users can then export line-level de-identified data at their fingertips.

Check out our user guide and this tutorial on how to use Leaf!


The TriNetX web application also enables you to get UCHealth patient cohort counts, work with Compass to reidentify those cohorts, and export de-identified data.


Check out additional information on how to reidentify TriNetX Cohorts,  download line-level de-identified data, view the TriNetX data dictionary, and FAQs about TriNetX.

Data Explorer Dashboards

To aid in developing inclusion/exclusion criteria for self-service or custom data extracts, Compass provides a series of Data Explorer Dashboards. These self-service tools enable users to explore codes for medications, labs, procedures, departments, flowsheets, and more.

To gain access to the Data Explorer Dashboards, please apply via our De-identified Data Access Agreement. Once you are granted access, connect to the CU Denver or CU Anschutz network (or VPN) to access the Data Explorer Dashboards.

Custom Data Extracts & Honest Broker Services

Our Data Delivery Team will work with you to develop a custom data extract. These extracts can be fully de-identified or, if necessary for research purposes may contain limited PHI. Compass can supply data  for research, QI, and administrative purposes. Our analysts can assist you to:

To get started on a custom data extract project, please complete and submit the Compass Data Request Questionnaire.

Compass can act as an honest broker by maintaining PHI when linking data from additional sources such as the Colorado Center for Personalized Medicine DNA Biobank.  

Compass can provide custom data extracts in three different formats:

Data requests are prioritized according to certain guidelines. You can review these guidelines on the Project Prioritization page.

Available Data

Compass integrates a variety of patient data from UCHealth, Children's Hospital of Colorado, and CU Medicine Practice Group. The local clinical data are augmented with All-Payer Claims data from the CIVHC and State Death Index data from the CDPHE. Datasets are hosted in Google Big Query and our unique Arbitrary system allows matching of patients between datasets whilst maintaining privacy. Data from UCHealth and CHCO goes back historically to 2011 and is current to the month.
