produces national estimates about emergency department (ED) visits across the country. The NEDS describes ED visits, regardless of whether they result in admission, and is an exceptional resource for conducting research on high-profile emergent health delivery issues. One of the most distinctive features of the NEDS is its large sample size, which allows for analysis across hospital types and the study of relatively uncommon disorders and procedures. The following links provide Stata load programs for the NEDS.

Documents are provided in Stata format and there is one Stata load program for each data file. Stata load programs are provided by year. The amount of time it takes to access a document depends on your machine, browser and Internet connection.

In total, the comma-delimited version of the NEDS is about 10 gigabytes (GB). The largest component is the NEDS Core file at almost 7 GB. Most versions of Stata requires that the data be loaded into memory; it will be difficult to load the NEDS Core File.
