Public Data Sets

Inpatient, Ambulatory Surgeries, Emergency Department Encounters and Claims Data

Public use data sets (PDS) are designed to provide general health care information to a wide spectrum of users with minimal controls. Considerable efforts are taken to ensure that individual patients cannot be identified from the PDS. Patient’s age, diagnosis codes, physician’s specialty, and payers are grouped and several data elements are encrypted under specific conditions. This data is available in two different data sets on CD ROM.

To order a data set, please fill out the online data request form.
