How is HCAI data protected? 

HCAI has collected, managed, and successfully protected sensitive and confidential health data for decades. HCAI ensures that the security, privacy, and confidentiality of consumers’ individually identifiable health information is protected in a manner consistent with state and federal privacy laws. All Californian’s are afforded a constitutional right to privacy and the state has long led the nation in developing robust privacy and security standards to protect personal information, particularly when it comes to information regarding individual health status. Consistent with this philosophy and history, a core principle is that protected sensitive and confidential health data managed by HCAI is used to learn and provide information about healthcare systems and populations at large, not individual patients. Only authorized individuals have access to these data.

The technology systems used to manage and store protected, sensitive, and confidential health data are administered with strict security and privacy procedures and controls, which include: regular mandatory role-based security and privacy training for all employees and contractors; encryption of data while in transit and at rest; strictly enforced least privileged access controls; rigorous back-up and recovery of data; and logging of all actions performed at the administrative, database, and application levels. These procedures and controls are overseen by HCAI’s Chief Information Security Officer and Chief Privacy Officer and comply with industry, state and federal standards. Security and privacy policies are reviewed annually and overseen by security governance that includes executive management and subject matter experts.

Release of protected, sensitive health data is tightly controlled by regulation and policy. Requestors seeking data from HCAI must first be approved and then follow strictly governed application processes, which include signing a Data Use Agreement (DUA). The HCAI DUA describes appropriate safeguards through “Required Practices for Safeguarding Access to Confidential Data.” Guidance is also included regarding security incident and data breach management and reporting; how to handle Business Associate Agreements; data record retention periods; and data destruction requirements. The HCAI DUA further explains appropriate Requestor data usage and aggregate reporting requirements for HCAI data, which comply with the CalHHS Data De-Identification Guidelines. The agreement also ensures that the Requestor and their Contractors are compliant with HCAI standards and requirements as outlined in the DUA. Failure of the Requestor to comply with all terms of the HCAI DUA can result in termination of the agreement and may subject the Requestor to legal action by the State. Separately, state entities are subject to a similar process memorialized in the California Health and Human Services Interagency Data Exchange Agreement.
