California Permission to Use Personal Health Information for Research is a process in which researchers must obtain permission from an individual before collecting, using, or disclosing their personal health information for research purposes. There are two types of permission that must be obtained in California: informed consent and authorization. Informed consent requires the researcher to provide all relevant information to the individual, including the purpose of the research, the risks involved, and the voluntary nature of participation. Authorization requires the individual to explicitly agree to the release of their personal health information for research purposes. This process is governed by the California Confidentiality of Medical Information Act (CIA) and the California Health and Safety Code.
