Statistics and Data Analysis: Retention and Penetration Rate Data
These data come from the Client and Services Information System (CSI) for fiscal years 2003-04, 2006-07 and 2007-08. There are two links for each county for each fiscal year as well as statewide links. The first link contains the penetration rate data, while the second link contains retention rate data.
Retention Rate Data
The retention rates are analyzed by race/ethnicity, gender, and age. The charts for retention illustrate the total number of CSI Clients served in FY 2003-04, 2006-07 and 2007-08 by number of services. County mental health programs provide service data on a monthly basis. Only clients receiving mental health services during FY 2003-04, 2006-07 and 2007-08 were counted. A basic principle of the CSI system is that it reflects both Medi-Cal and non-Medi-Cal clients, and services provided in the County/City/Mental Health Plan program. This includes all providers whose legal entities are reported to the County Cost Report under the Treatment Program.
Penetration Rate Data
The second link for each county and fiscal year contains a set of graphs displaying the penetration rates, referred to as “Comparison of Total Clients to Holzer Targets” and “Percent Difference from Target.” The graphs display a comparison of totals vs. estimates of the prevalence of serious mental illness/serious emotional disturbance in California. The results were based on estimates of need for Mental Health Services developed by Charles Holzer from the University of Texas. These estimates represent "targets" and are compared across gender, race/ethnicity, and age to service data obtained through DMH's CSI. When considering these penetration rates, it is important to remember that they are based on census data combined with estimates that were calculated by applying prediction weights. Due to the way census data is updated, the data in the tables should be viewed as "best available" and should be checked and/verified at the local level where numbers do not appear to represent actual local population data.
