Clinical & Health Informatics Institute (CHI2)

The Clinical & Health Informatics Institute (CHI or CHI2) is a critical resource to optimize the conduct of high quality translational research, providing the computational and informational infrastructure that underlies all phases of investigation from planning to analysis.  Since 2011, the ICTR informatics infrastructure has significantly enhanced support for clinical and translational research, serving investigators at UW-Madison and Marshfield Clinic. The CHI2 team assists investigators during project conceptualization, grant submission, and deployment of secure data storage and processing methods.

Three service areas available to support your research are described briefly below, however we are regularly introducing new service lines.

You’re encouraged to submit an online consultation form to connect with a CHI2 team member for any of the topics below!

Data Resources and Services

Preparatory to Research

The ICTR CHI2 team offers a number of resources and services that are essential to inform and shape successful research projects.  Two preparatory to research services lines are the self-service i2b2 or the analyst-driven Clinical Research Data Service (CRDS).

Research Support Systems

The CHI2 team also provides support and access to systems that support clinical research such as REDCap data storage and OnCore clinical trial management system.

Consultations in Advanced Informatics Techniques

Natural Language Processing (NLP)

ICTR CHI2 provides expertise in Natural Language Processing (NLP) to assist researchers with searches of the electronic data warehouse for all types data associated with the EHR. NLP is a field of computer science, artificial intelligence, and computational linguistics concerned with the interactions between computers and human (natural) languages.  NLP methods have the capacity to examine both the narrative text and related unstructured data, e.g., X-rays, etc., in the EHR. NLP allows such EHR data to be transformed into rich and meaningful discrete data elements for research within a secured environment.

Please submit a consult request to learn more about working with CHI2 experts in this area. Check “I’d just like to start by talking to someone” or “What I’m interested in isn’t on the list” and describe your research needs in the Notes fields.
