California Health and Human Service Agency (CHHS) Open Data Portal (ODP)

The California Health and Human Service Agency (CHHS) Open Data Portal (ODP) provides the public with non-confidential health and human service data. The Research and Analytics Branch releases data estimates to the CHHS-ODP that are considered critical to the branchā€™s work in providing vital statistics data. CHHS-ODP provides standardized data that can be easily retrieved, combined, downloaded, sorted, searched, analyzed, redistributed and re-used by individuals, business, researchers, journalists, developers, and government to process, trend, and innovate.

California Integrated Vital Records System (Cal-IVRS)

California Integrated Vital Records System (Cal-IVRS) is a platform designed, developed, and implemented for the California Department of Public Health (CDPH) through a contract with UC San Diego. CDPH is responsible for reporting this data to National Center for Health Statistics (NCHS). Cal-IVRS is used by public health jurisdictions to collect data and register death certificates, fetal death certificates, and birth certificates.

California Vital Data (Cal-ViDa)

California Vital Data (Cal-ViDa) is a query tool that allows users to create custom queries using California's birth and death data. New data is added on a monthly basis. Birth data is available from 2018 onwards and death data is available from 2014 onwards. Due to differences in legacy files, no earlier data will be accessible from the application. All reports can be divided by individual years (disaggregated by year), or divided by individual month within each year (disaggregated by year and month).

Cause of Death Coding

CDPH daily transmits the registered death information to the CDC National Center for Health Statistics and Informatics (NCHS). The cause-of-death information reported on the death certificate is subsequently coded and classified using the current revision of ICD, version 10 for Mortality (ICD-10), by the CDC NCHS and sent back to CDPH.

See glossary term(s): International Statistical Classification of Diseases (ICD), Cause of Death

Return to the top


Cause of Death

Describes the disease or other morbid condition responsible for death.  The cause of death section on the death certificate is used to collect information from the physician/coroner/medical examiner who certifies the cause-of-death information on the diseases and other conditions and chain of events leading directly death. For more information please see Instructions for Completing the Cause-of-Death Section on the Death Certificate (PDF).

Committee for the Protection of Human Subjects (CPHS)

Committee for the Protection of Human Subjects (CPHS) serves as the institutional review board (IRB) for California Health and Human Services (CalHHS). The role of the CPHS (and other IRBs) is to ensure that research involving human subjects is conducted ethically and with minimal risk to participants. Review the findings of the committee for the protection of human subjects pursuant to subdivision (c) of Section 102430 and make recommendations to the State Registrar regarding all requests for studies that propose to use confidential information with respect to whether a legitimate scientific interest is presented and whether the significance of the project justifies use of the confidential information.

D

Data De-identification Guidelines (DDG)

Describes the procedure to be used by departments and offices in the California Health and Human Services Agency (CHHS) to assess data for public release. These steps are intended to assist departments in assuring that data is de-identified for purposes of public release that meet the requirements of the California Information Practices Act (IPA) and the Health Insurance Portability and Accountability Act (HIPAA) to prevent the disclosure of personal information. As a result, tabulated data counts less than 11 may be suppressed to protect privacy, and additional suppression may be applied to complementary cells to prevent the inference of the values of suppressed cells.  Agency DDG must be applied to all summarized/tabular data among all Departments and Programs within Agency that report information about individuals.

F

Fetal Death

Defined as death before the complete expulsion or extraction from the mother of a product of human conception, irrespective of the duration of pregnancy that is not an induced termination of pregnancy. The death is indicated by the fact that, after such expulsion or extraction, the fetus does not breathe or show any other evidence of life such as beating of the heart, pulsation of the umbilical cord, or definite movement of voluntary muscles. Heartbeats are to be distinguished from transient cardiac contractions; respirations are to be distinguished from fleeting respiratory efforts or gasps. California law requires all fetal deaths to be registered within eight days of the fetal death event. The California Department of Public Health (CDPH) is responsible for timely fetal death registrations as mandated by Health and Safety Code (HSC) Section 102950.
