Background : Homeless persons with substance use disorders (SUD) have high disease risk, poor access to health care, and are frequent users of Medicaid and other social services. Low-demand supportive housing with no prerequisites for treatment or sobriety has been shown to improve housing stability and decrease public service use for chronically homeless persons with serious mental illness (SMI) and chronic medical conditions. The impact of low-demand housing on individuals with SUD but without co-occurring SMI has been little studied. This evaluation compares housing retention and use of crisis public services (jail, emergency department visits, hospitalization, and substance detoxification) between individuals treated and untreated for SUD before move-in to a low-demand supportive housing program in New York City. Methods : The authors used matched administrative records for individuals with SUD but no SMI placed in supportive housing during 2007-2012. Participants received SUD treatment ( n = 1425; treated participants) or were not treated ( n = 512; active users) at housing application. Propensity score-weighted regression analyses were used to best estimate the effect of SUD treatment on incarceration, public service utilization, and housing retention. Results : Persons not treated for SUD had a significantly longer tenure in supportive housing than treated participants. However, not treated tenants were more likely to be incarcerated. Opioid agonist therapy and older age decreased the risk of housing discharge, whereas detoxification and inpatient SUD treatment increased the risk of discharge. Conclusions : Persons with SUD can achieve residential stability in supportive housing that does not require SUD treatment before admission.

Former foster youth are at increased risk of housing instability and sexually transmitted infections (STIs) during the transitional period following foster care. We measured housing stability using sequence analysis and assessed whether a supportive housing program in New York, New York, was effective in improving housing stability and reducing STIs among former foster youth. Matched administrative records identified 895 former foster youth who were eligible for the housing program during 2007-2010. The main outcomes included housing stability (as determined from episodes of homelessness, incarceration, hospitalization, and residence in supportive housing) and diagnosed STI case rates per 1,000 person-years during the 2 years after baseline. Marginal structural models were used to assess impacts of the program on these outcomes. Three housing stability patterns (unstable housing, stable housing, and rare institutional dwelling patterns) were identified. The housing program was positively associated with a pattern of stable housing (odds ratio = 4.4, 95% confidence interval: 2.9, 6.8), and negatively associated with diagnosed STI rates (relative risk = 0.3, 95% confidence interval: 0.2, 0.7). These positive impacts on housing stability and STIs highlight the importance of the supportive housing program for youths aging out of foster care and the need for such programs to continue., (© The Author(s) 2017.

The federal Housing Opportunities for Persons with AIDS (HOPWA) program addresses housing needs of low-income persons living with HIV/AIDS (PLWHA). The New York City (NYC) Department of Health and Mental Hygiene oversees 22 HOPWA contracts for over 2,400 clients, and manages the NYC HIV Registry. HOPWA clients (N = 1,357) were matched to a random 20 % sample of other PLWHA (N = 13,489). Groups were compared on HIV care retention, viral suppression, and rebound. HOPWA clients were, on average, 3 years younger and more likely to be concurrently diagnosed with HIV and AIDS. While HOPWA clients were more likely to be retained in care (94 vs. 82 %; mOR = 2.97, 95 % CI 2.35-3.74), they were no more likely to achieve suppression (84 vs. 86 %; mOR = 0.85, 95 % 0.70-1.03) and were more likely to rebound (11 vs. 7 %; mOR = 1.45; 95 % CI 1.10-1.91). HIV care retention does not fully translate to virologic suppression in this low-income service population.

Background: Hepatitis C virus (HCV) infection disproportionately impacts people experiencing homelessness. Hepatitis C virus can lead to negative health outcomes, including mortality. We evaluated the impact of a permanent supportive housing (PSH) program (ie, "treatment") on liver-related morbidity and mortality among persons with chronic homelessness and HCV infection.Methods: We matched records for persons eligible for a New York City PSH program (2007-2014) with Heath Department HCV and Vital Statistics registries and Medicaid claims. Among persons diagnosed with HCV before or 2 years posteligibility, we added stabilized inverse probability of treatment weights to negative binomial regression models to compare rates for liver disease-related emergency department visits and hospitalizations, and hazard ratios for mortality, by program placement 2 and 5 years posteligibility.Results: We identified 1158 of 8783 placed and 1952 of 19 019 unplaced persons with laboratory-confirmed HCV infection. Permanent supportive housing placement was associated with significantly reduced liver-related emergency department visits (adjusted rate ratio [aRR] = 0.76, 95% confidence interval [CI] = .61-.95), hospitalizations (aRR = 0.62, 95% CI = .54-.71), and all-cause (adjusted hazard ratio [aHR] = 0.65, 95% CI = .46-.92) and liver-related mortality (aHR = 0.72, 95% CI = .09-.83) within 2 years. The reduction remained significant for hospitalizations after 5 years.Conclusions: Placement into PSH was associated with reduced liver-related morbidity and mortality among persons with HCV infection and chronic homelessness.

Objective: Homeless persons are at high risk for poor oral health. Supportive housing can improve housing stability for persons with behavioural health conditions, but its impact on dental service use has been little studied. Methods: Data for this evaluation come from matched public service records for eligible applicants to a New York City supportive housing program (NY III) targeting chronic homelessness. NY III tenants (N = 5678) were compared with applicants not placed in housing (N = 6536) and applicants placed in other supportive housing programmes (N = 4823). Regression analysis was used to assess the association between supportive housing, primary care use, clinical severity and the likelihood of dental visits. Results: Over four observation years, 71% of applicants had at least one dental visit for any cause and 57% for preventive dental care. Incidence of dental visits was lower for persons with physical disability (IRR = 0.91; 95% CI = 0.85, 0.97, P =.003), psychiatric hospital stays (IRR = 0.78; 95% CI = 0.68, 0.88, P <.001) and age over 54. Persons engaged in primary care (IRR = 1.26; 95% CI = 1.21, 1.31, P <.001) and outpatient mental health care (IRR = 1.16; 95% CI = 1.12, 1.21, P <.001) had greater incidence of dental visits. Conclusions: Supportive housing was associated with greater dental service use. The positive association between primary care, mental health care and dental care suggests important points of entry for dental care. Oral health education and service referrals in supportive housing and primary care settings may improve oral health service delivery to persons experiencing social exclusion due to homelessness, mental illness and poor oral health.

Supportive housing addresses a fundamental survival need among homeless persons, which can lead to reduced risk of diabetes mellitus and improved diabetes care. We tested the association between supportive housing and diabetes outcomes among homeless adults who were eligible for New York City's supportive housing program in 2007–2012. We used multiple administrative data sources, identifying 7,525 Medicaid-eligible adults. The outcomes included receiving medical evaluation and management services, hemoglobin A1C and lipid testing (n = 1,489 persons with baseline diabetes), and incidence of new diabetes diagnoses (n = 6,036 persons without baseline diabetes) in the 2 years postbaseline. Differences in these outcomes by placement were estimated using inverse-probability-of-treatment weighting. Placed persons were more likely to receive evaluation and management services (relative risk (RR) = 1.03, 95% confidence interval (CI): 1.01, 1.04) than unplaced persons. For those with baseline diabetes, placed persons were more likely to receive hemoglobin A1C tests (RR = 1.10, 95% CI: 1.02, 1.19) and lipid tests (RR = 1.09, 95% CI: 1.02, 1.17). For those without baseline diabetes, placement was also associated with lower risk of new diabetes diagnoses (RR = 0.87, 95% CI: 0.76, 0.99). These findings show that benefits of supportive housing may be extended to diabetes care and prevention. [ABSTRACT FROM AUTHOR]

Background: A rapid increase of Medicaid expenditures has been a serious concern, and housing stability has been discussed as a means to reduce Medicaid costs. A program evaluation of a New York City supportive housing program has assessed the association between supportive housing tenancy and Medicaid savings among New York City housing program applicants with serious mental illness and chronic homelessness or dual diagnoses of mental illness and substance use disorder, stratified by distinctive Medicaid expenditure patterns.Methods: The evaluation used matched data from administrative records for 2827 people. Sequence analysis identified 6 Medicaid expenditure patterns during 2 years prior to baseline among people placed in the program (n = 737) and people eligible but not placed (n = 2090), including very low Medicaid coverage, increasing Medicaid expenditure, low, middle, high, and very high Medicaid expenditure patterns. We assessed the impact of the program on Medicaid costs for 2 years post-baseline via propensity score matching and bootstrapping.Results: The housing program was associated with Medicaid savings during 2 years post-baseline (-$9526, 95% CI = -$19,038 to -$2003). Stratified by Medicaid expenditure patterns, Medicaid savings were found among those with very low Medicaid coverage (-$15,694, 95% CI = -$35,926 to -$7983), increasing Medicaid expenditures (-$9020, 95% CI = -$26,753 to -$1705), and high Medicaid expenditure patterns (-$14,450, 95% CI = -$38,232 to -$4454). Savings were largely driven by shorter psychiatric hospitalizations in the post-baseline period among those placed.Conclusions: The supportive housing program was associated with Medicaid savings, particularly for individuals with very low Medicaid coverage, increasing Medicaid expenditures, and high Medicaid expenditures pre-baseline.

Objectives: As gentrification continues in New York City as well as other urban areas, residents of lower socioeconomic status maybe at higher risk for residential displacement. Yet, there have been few quantitative assessments of the health impacts of displacement. The objective of this paper is to assess the association between displacement and healthcare access and mental health among the original residents of gentrifying neighborhoods in New York City. Methods: We used 2 data sources: 1) 2005–2014 American Community Surveys to identify gentrifying neighborhoods in New York City, and 2) 2006–2014 Statewide Planning and Research Cooperative System. Our cohort included 12,882 residents of gentrifying neighborhoods in 2006 who had records of emergency department visits or hospitalization at least once every 2 years in 2006–2014. Rates of emergency department visits and hospitalizations post-baseline were compared between residents who were displaced and those who remained. Results: During 2006–2014, 23% were displaced. Compared with those who remained, displaced residents were more likely to make emergency department visits and experience hospitalizations, mainly due to mental health (Rate Ratio = 1.8, 95% confidence interval = 1.5, 2.2), after controlling for baseline demographics, health status, healthcare utilization, residential movement, and the neighborhood of residence in 2006. Conclusions: These findings suggest negative impacts of displacement on healthcare access and mental health, particularly among adults living in urban areas and with a history of frequent emergency department visits or hospitalizations.

Evidence on ethnic enclave-health associations for Asian Americans is limited due to an inconsistent definition of ethnic enclave. The authors aimed to establish a robust criterion for defining Asian enclaves in New York City (NYC) and assessed the association between enclave residence and health outcomes among Asian American adults. Data came from 2009-2012 NYC Community Health Surveys and 2008-2012 American Community Survey. Asian enclave was defined as an area with high dissimilarity and isolation scores as well as high concentration of Asians. Five of 55 NYC community districts were identified as Asian enclaves. After controlling for confounding, enclave residence was associated with positive perception of general health with borderline significance (prevalence ratio = 1.06, 95 % CI 0.98, 1.15), but not with current smoking, hypertension, and diabetes. Ethnic enclave residence in urban areas may not produce a substantial impact on chronic health outcomes for Asian Americans beyond individual-level factors. [ABSTRACT FROM AUTHOR]

Purpose: Homeless persons with a substance use disorder (SUD) are at high risk of emergency department (ED) visits and hospitalizations. We evaluated the impact of supportive housing on SUD-related ED visits and hospitalizations among active substance users experiencing chronic homelessness.Methods: We matched 1558 homeless adults eligible for a New York City supportive housing program who had a SUD (2007-2012) to Medicaid claims data. We examined SUD-related hospitalizations and ED visits 2 years posteligibility. We calculated stabilized inverse probability of treatment weights using baseline demographic and clinical characteristics and used doubly robust estimators to compare rates between persons placed into supportive housing and those eligible but not placed. We also examined outpatient SUD treatment.Results: Placed persons were hospitalized and visited EDs for substance use at significantly lower rates than persons not placed into housing (adjusted rate ratio, 0.70; 95% confidence interval, 0.56-0.88 and adjusted rate ratio, 0.46; 95% confidence interval, 0.31-0.68, respectively) 2 years posteligibility. Placed persons had increased odds of a new episode of SUD treatment and initiating treatment.Conclusions: Supportive housing placement was associated with decreases in SUD-related hospitalizations and ED visits and with increased odds of new episodes of SUD outpatient treatment among homeless persons with SUD.
