Thank you for your interest in using NC DETECT for public health research purposes.

Before you submit your data request, you must go through a data request presentation. The presentation will:

  • Give you a brief overview of NC DETECT
  • Describe the data available in NC DETECT
  • Walk you through the data request process

After completing the presentation, you will be directed to the online data request submission form. The data request submission form requires information on the following:

  • Primary requester contact information and information for all co-requesters (anyone who will have access to the dataset provided)
  • Research purpose and public health significance
  • How the research will be used (presentation, publication, grant application, dissertation, etc.)

We strongly recommend contacting us at ncdetect@listserv.med.unc.edu to discuss your data request before submission.

Due to severe resource limitations, research data requests may take several months to be processed.

To expedite the data request process, the NC Division of Public Health has developed a standardized limited dataset of NC DETECT emergency department data that serves the needs of most applied public health researchers. The data elements included in this dataset are listed in the table below. Requesting this limited dataset rather than a customized one is strongly encouraged.
