To create a full inventory of CDC’s surveillance systems, programs, registries, health surveys, tools, and collaboratives.

Summary + Outcome

A comprehensive, real-time, interactive resource for CDC, its partners, and the public to explore and discover information about the full inventory of CDC’s surveillance systems, programs, registries, health surveys, tools, and collaboratives. CDC Integrated Surveillance Portal (CISP) contains not only descriptive information about these CDC resources — CISP also describes the relationships between resources. The information in this tool is from many sources, including the National Public Health Surveillance and Biosurveillance Registry for Human Health. This portal does not contain raw surveillance data — it only contains meta-data (i.e., data about data) regarding these surveillance activities. Because CISP holds no surveillance data, it holds no personally identifiable information, nor personal health information about cases or persons in these systems.

Advanced prototype features (in early development phase):

Sankey Diagram Visualization of CISP data can be viewed here.  Use SS15 and P28 as examples.

For advanced – actual data set integration / merging (not metadata):

CISP Data Harmonization tool (alpha):

This tool allows viewing, merging and cleaning of selected data sets.

Use DSET2 & DSET14 as examples.

Data element standardization is carried out through the use of the Unified Medical Language System (UMLS).  Creating a new data element requires logging in.  Please contact IIU for a demonstration and/or access.

Once you have access, you can use this link to edit the general metadata of a sample data set, and this link to edit the actual data elements within the data set.
