The California Office of Statewide Health Planning and Development (OSHPD) provides confidential patient-level data sets to researchers eligible through the Information Practices Act (CA Civil Code Section 1798 et seq.), which permits nonprofit educational institutions (such as the University of California) and state agencies to request data for research purposes and for performing legally mandated activities.

2018 is the most recent year available for Patient Discharge, Emergency Department, and Ambulatory Surgery Data.

Request Research Data#

If you wish to submit a Research Data Set Request, please submit a completed request packet including an UNSIGNED word document of your request to dataandreports@oshpd.ca.gov for preliminary review. An analyst will contact you about your request within 5 business days. Please see the checklist and instructions below for completing forms and documents.

You will also need to register on the California Committee for the Protection of Human Subjects (CPHS) website if you have not already done so.  Initiate the IRBManager process and follow the CPHS instructions on how to prepare a draft Research Protocol.  When submitting your request documents to OSHPD, include a PDF of your draft CPHS Protocol as we also review it with your request.  An OSHPD request submitted without a draft Research Protocol will be delayed until you provide us a copy.

Research Data Set Request Process#

Below are the OSHPD forms for requesting research data referenced here.  Please use the checklist and instructions while completing the request. Information is also provided in the instructions about other forms not maintained or provided by OSHPD that may be required to process a request.
