Environmental Public Health Tracking Data Set Summary, Hospitalizations   

Characteristic	Description
Data Source	State and Local Data Systems
Purpose	This data set will be used to calculate measures related to asthma, acute myocardial infarction, carbon monoxide poisoning, heat stress illness, and chronic obstructive pulmonary disease hospitalizations as described in the Part 1 package, for use on the national public portal.
Geographic Level	The smallest geographic unit to be represented in this data set is the census tract.
Restrictions	This is a restricted access data set. Data will be displayed via the national public portal only when sufficient conditions have been met to protect data privacy. Only registered users will have direct access to this data set via the national secure portal.

NOTE: When preparing the data file, the sequence of data elements (i.e., field names) in the data file can be found in the schema for each health outcome.
