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.
To order a data set:
1. Please read important data request information.
We attempt to review every request within a week of receipt by the Office. Every data request is reviewed by the Privacy Officer and Office Director and requires approval from each person.
Typically a preliminary decision on your request is made within 2 weeks after original submission. Decisions may take longer if the request needs additional information or concerns identifiable data.
For all special requests, our staff will need to assess the feasibility of the request, anticipated cost, and estimated time for completion.
Please be advised that all requests for identifiable data require additional documentation and approvals.
2. Complete the online data request form.
