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. Patients age, diagnosis codes, physicians specialty, and payers are grouped and several data elements are encrypted under specific conditions.
