DocGraph US Provider Teaming Data
The DocGraph Teaming data set shows how healthcare providers in the United States team together to provide care to Medicare patients.
The dataset is a simple graph data structure, using the National Provider Identifier as keys. We have not heard of a larger, publicly available graph data set that uses real identities.
This file contains the links to both the data sets (which are many Gigabytes even as zip files) as well as the documentation for the data.
Note: On Oct 5 2015, this data set was redacted due to signifigant issues with its content vs documentation. On Dec 15 2015, this data, along with updated documentation, was replaced. http://www.docgraph.com/teamingdatav2/
