DAWN

Overview

The Drug Abuse Warning Network (DAWN) is a national health surveillance system that records drug use contributing to hospital emergency department visits throughout the United States. Hyperedges in this dataset are the drugs used by a patient (as reported by the patient) in an emergency department visit. The drugs include illicit substances, prescription and over-the-counter medication, and dietary supplements. Timestamps of visits (under the `timestamp` attribute of the hyperedges) are recorded at the resolution of quarter-years, spanning a total duration of 8 years (2004 to 2011). The names of the drugs are encoded in the `name` attribute of the nodes.

This is a temporal hypergraph dataset, which here means a sequence of timestamped hyperedges where each hyperedge is a set of nodes. Timestamps are in ISO8601 format. In the original dataset, the same drug substance can have more than one NDC code. For example, different dosages of the same drug may result in multiple NDC codes.
