Office of Health Assessment and Epidemiology

Welcome to the Office of Health Assessment and Epidemiology.


The Office of Health Assessment and Epidemiology is comprised of the following units:

Data Collection and Analysis (DC&A)
This unit is responsible for three State-mandated subunits: 1) Vital Records Office (births and deaths); 2) Medical Marijuana Identification Program (MMIP); and 3) Morbidity Unit (communicable disease reporting).   DC&A ensures the timely collection of data and prepares data for analysis by County department and other non-county agencies.

Epidemiology Unit
This unit provides epidemiologic support, training, and other assistance to public health programs, community partners, and other organizations that do not have this capacity. It also coordinates Geographic Information Systems (GIS) support, training, and resources for the department.

Community Health Assessment Unit
This unit conducts the Los Angeles County Health Survey (LACHS), a large population-based survey that provides information concerning the health of Los Angeles County residents.

Institutional Review Board (IRB)
The IRB reviews and monitors all DPH-related research and evaluation projects involving collection or analysis of data from or about human subjects. The IRB provides training, consultation and policy direction for DPH on the ethics and integrity of research and other data collection.

Policy Analysis Unit
This unit provides technical assistance, consultation, and training to public health programs in conducting policy-related economic evaluations.

Our Mission
To ensure the availability of high-quality and comprehensive health data on the Los Angeles County population and to facilitate its use for public health assessment, policy development, and program planning and evaluation.
