A spatial analysis of Los Angeles County's burden of serious mental illness in relation to public mental health service providers

Purpose The purpose of this paper is to identify regions of Los Angeles County with high burdens of serious mental illness and determine whether these regions align with those experiencing the greatest economic hardship. Design/methodology/approach This cross-sectional study analyzed the estimated prevalence of serious mental illness and the locations of publicly funded mental health service providers within each census tract of Los Angeles County. The burden of serious mental illness was calculated for each census tract using these variables and an optimized hot spot analysis was conducted to determine which regions were the most underserved in terms of serious mental illness. Findings There is a significantly higher burden of serious mental illness in Southeastern Los Angeles and Pomona Valley than in the rest of Los Angeles County (p = 0.01). The same can be said regarding the Lancaster-Palmdale area and San Fernando Valley (p = 0.05). These areas do appear to align with the areas of Los Angeles County with an economic hardship index in the fourth quartile. Originality/value Mental health initiatives targeting the four hot spot regions should be given priority by the County of Los Angeles. This is especially true when allocating funds from Proposition 63, which aims to address mental health disparities in underserved, unserved or inappropriately served populations.
