The Health Assessment Unit makes up part of the
Office of Health Assessment and Epidemiology (OHAE),
along with the Epidemiology Unit, the Data Collection
and Analysis Unit, and the Institutional Review Board,
in the Department of Public Health. OHAE is overseen by
the Chief Science Officer.
The Health Assessment Unit
oversees the development of the
Los Angeles County Health Survey (LACHS), a
population-based telephone survey which collects data on
health conditions, health behaviors, and health care
access and utilization of services from a representative
sample of Los Angeles County residents. The unit also provides data
support, along with the other units of OHAE, for Area
Health Officers and their respective staffs for the
purpose of improving community health.
