RESUMEN
The purpose of this study was to use geospatial indicators of mental health need and homelessness in Los Angeles County Service Planning Areas (SPAs) and a psychiatric sample of adults who were homeless to investigate 1) overlap between SPA level of mental health need and corresponding volume of involuntary psychiatric hospitalizations over time; 2) overlap between SPA level of unsheltered homelessness and corresponding volume of involuntary psychiatric hospitalizations over time; and 3) associations between SPA level of mental health need, SPA level of unsheltered homelessness, and initiation of a mental health conservatorship for grave disability. A sample of 373 adults who were homeless and hospitalized on an involuntary psychiatric hold from 2016 to 2018 were linked to data from the Greater Los Angeles Homeless Count on unsheltered homelessness and from the California Health Interview Survey on need for mental health services and suicidality, using admission zip codes to link variables at the SPA level. Geospatial mapping and bivariate tests were used to examine geographic overlap of SPA mental health need and unsheltered homelessness with volume of involuntary psychiatric admissions over the study period. Multiple logistic regression modeling was used to examine associations of SPA mental health need and unsheltered homelessness with conservatorship initiation. The volume of patients admitted from SPAs with higher levels of mental illness need grew from 2016 to 2018 (Tau = 0.27, P < 0.001; Tau = 0.40, P < 0.001), but there were fewer patients admitted from SPAs with higher levels of unsheltered homelessness over the same years (Tau of -0.33, P < 0.001). Being admitted from SPAs with the highest levels of unsheltered homelessness was associated with higher odds of conservatorship initiation (OR = 1.73, 95% CI = 1.82-16.74). Results suggest a need for targeted mental health and housing services to reach areas of highest need in Los Angeles County.
RESUMEN
OBJECTIVE: The purpose of this study was to examine associations between homelessness and length of psychiatric hospitalization and to explore the role of mental health conservatorship in determining discharge location for patients who are homeless and have a grave disability from serious mental illness. METHODS: This observational study used administrative data from a safety-net psychiatric hospital in Los Angeles. The sample included 795 adults (≥18 years) who were hospitalized on an involuntary psychiatric hold between 2016 and 2018. The outcome variables were length of stay (days) and discharge location (home, locked psychiatric facility, unlocked psychiatric facility, unhoused). The predictor variables were homelessness status and whether a mental health conservatorship was initiated during hospitalization. Multiple regression models were used to estimate associations between variables. RESULTS: Homelessness status was associated with 27.5 additional days (SE=3.5 days) of hospitalization in adjusted models. Homeless patients for whom conservatorship was initiated comprised 6% of the sample but 41% of total inpatient days. Among people who were homeless, initiation of a conservatorship was associated with significantly longer length of inpatient stay (mean=154.8 days versus 25.6 days for the whole sample) but also with lower odds of being unhoused at the time of discharge (risk ratio=0.19, 95% confidence interval=0.09-0.34). CONCLUSIONS: A mental health conservatorship can be a mechanism for helping homeless people with a grave disability from mental illness to transition from the streets to residential psychiatric treatment, but it requires substantial resources from facilities that initiate such conservatorships and does not guarantee resolution of long-term supportive housing needs.
