Investigation of racial and ethnic disparities in service utilization among homeless adults with severe mental illnesses

Mental Health Disparities, Treatment Engagement, and Attrition Among Racial/Ethnic Minorities with Severe Mental Illness: A Review

Mounting evidence indicates that there are mental health disparities in the United States that disadvantage racial/ethnic minorities in medical and mental health settings. Less is known, however, about how these findings apply to a particularly vulnerable population, individuals with severe mental illness (SMI). The aim of this paper is to (1) provide a critical review of the literature on racial/ethnic disparities in mental health care among individuals with SMI; (2) identify factors which may contribute to the observed disparities; and (3) generate recommendations on how best to address these disparities. Specifically, this article provides an in-depth review of sociocultural factors that may contribute to differences in treatment engagement and rates of attrition from treatment among racial/ethnic minorities with SMI who present at medical and mental health facilities. This review is followed by a discussion of specific strategies that may promote engagement in mental health services and therefore reduce racial/ethnic disparities in SMI.

Exploring the Intersections of Trauma, Structural Adversity, and Psychosis among a Primarily African-American Sample: A Mixed-Methods Analysis

Traumatic life events (TLEs) have been associated with multiple psychiatric diagnoses, including anxiety disorders, major depression, PTSD, and psychosis. To advance our understanding of the complex interactions between forms of adversity as they manifest across the lifespan, psychosis, and symptom content, we undertook a mixed-methods investigation of TLEs and psychosis. Our research explored the association between cumulative exposures, type of TLE, and proximity to the traumatic event and psychosis; the association between TLEs and clinical symptomology including specific types of delusions and/or hallucinations; and how qualitative data further inform understanding of complex relationships and patterns of past trauma and symptoms as they unfold over time. There were a total of 97 participants in the quantitative study sample, 51 participants with present state psychosis and 46 non-clinical. There were a total of 34 qualitative study participants, all of whom were experiencing psychosis. The quantitative analysis showed that when comparing persons with psychosis to the non-clinical group, there were no group differences in the overall total score of TLEs. However, there was a significant difference in cumulative TLEs that "Happened," demonstrating that as the number of TLEs increased, the likelihood of clinical psychosis also increased. We also found a correlation between lifetime cumulative TLEs that "Happened" and PANSS five-factor analysis: positive, excitement, depression, thought disorder, activation, and paranoia scores. The qualitative analysis further built on these finding by providing rich narratives regarding the timing of trauma-related onset, relationships between trauma and both trauma-related and religious-spiritual content, and trauma and hallucinatory modality. Analysis of participant narratives suggests the central role of localized cultural and sociopolitical influences on onset, phenomenology, and coping and contributes to a growing literature calling for strengths-based, client-driven approaches to working with distressing voices and beliefs that centers the exploration of the personal and social meaning of such experiences including links to life narratives. Findings also underscore the clinical importance of trauma assessment and trauma-informed care.

The effectiveness of a Housing First adaptation for ethnic minority groups: findings of a pragmatic randomized controlled trial

BACKGROUND

Little is known about the effectiveness of Housing First (HF) among ethnic minority groups, despite its growing popularity for homeless adults experiencing mental illness. This randomized controlled trial tests the effectiveness of a HF program using rent supplements and intensive case management, enhanced by anti-racism and anti-oppression practices for homeless adults with mental illness from diverse ethnic minority backgrounds.

METHODS

This unblinded pragmatic field trial was carried out in community settings in Toronto, Canada. Participants were 237 adults from ethnic minority groups experiencing mental illness and homelessness, who met study criteria for moderate needs for mental health services. Participants were randomized to either adapted HF (n = 135) or usual care (n = 102) and followed every 3 months for 24 months. The primary study outcome was housing stability; secondary outcomes included physical and mental health, social functioning, quality of life, arrests and health service use. Intention to treat statistical analyses examined the effectiveness of the intervention compared to usual care.

RESULTS

During the 24-month study period, HF participants were stably housed a significantly greater proportion of time compared to usual care participants, 75 % (95 % CI 70 to 81) vs. 41 % (95 % CI 35 to 48), respectively, for a difference of 34 %, 95 % CI 25 to 43. HF also led to improvements in community integration over the course of the study: the change in the mean difference between treatment groups from baseline to 24-months was significantly greater among HF participants compared to those in usual care (change in mean difference = 2.2, 95 % CI 0.06 to 4.3). Baseline diagnosis of psychosis was associated with reduced likelihood of being housed ≥ 50 % of the study period (OR = 0.37, 95 % CI 0.18 to 0.72).

CONCLUSION

Housing First enhanced with anti-racism and anti-oppression practices can improve housing stability and community functioning among ethnically diverse homeless adults with mental illness.

Measurement of Perceived and Technical Quality of Care for Depression in Racially and Ethnically Diverse Groups

Measurement of patient satisfaction is now considered essential for providing patient centered care and is an important tool for addressing health care disparities. However, little is known about how ethnically and racially diverse (ERD) groups differ in how they perceive quality, and widely used instruments for measuring perceived quality give little attention to cultural elements of care. This study examined the relationship between the culturally determined beliefs and expectations of four ERD groups (African Americans, Latinos, Portuguese-speakers, and Haitians, total N = 160) and the technical quality of treatment for depression provided in four "culturally-specific" primary care clinics. Using data from the Experiences of Care and Health Outcomes survey, chart reviews and focus groups, the study addressed a set of questions related to the psychometric properties of perceived care measures and the technical quality of care. The groups differed in preferred cultural elements except all preferred inclusion of religion. They did not differ in overall perceived quality. Technical quality was higher for Portuguese and Haitians than for African Americans and Latinos. Implications of group differences for measuring quality are discussed.

Distinct Coping Combinations are Associated with Depression and Support Service Utilization in Men who have Sex with Men Living with HIV

Stigma and stress may place HIV-positive men who have sex with men (HIV+ MSM) at risk for depression. Additionally, HIV+ MSM might utilize multiple HIV-related services as a way to gain support for, and more effectively manage, HIV-related stressors. Although prior research has demonstrated that depression severity and utilizing support services are associated with functional or dysfunctional coping strategies, researchers have not investigated the impact of different coping combinations-specifically, the concurrent use of functional and dysfunctional strategies-in this population. Thus, we explored (1) how items on one measure of coping, the Brief COPE, capture HIV-related coping of HIV+ MSM using Principal Components Analysis, (2) how HIV+ MSM's coping groups into unique combinations, and (3) how these coping combinations relate to depression and the scope of HIV-related support service utilization. Our sample consisted of 170 HIV+ MSM engaged with medical care. Results indicated the use of both functional and dysfunctional coping strategies. Unique combinations of functional and dysfunctional strategies showed differential associations with depression and the extent of HIV-related support service utilization. Specifically, individuals who engaged in low levels of both functional and dysfunctional coping, compared to individuals who more frequently engaged in functional coping strategies, were significantly less likely to utilize a range of critical HIV-related services. Individuals who reported frequent use of dysfunctional coping strategies, regardless of functional coping strategy use, reported higher levels of depression. Therefore, providers should continue to focus more closely on identifying functional coping strategies and reducing dysfunctional coping when working with HIV+ MSM.

Mental health care utilization at a free drop-in youth center in St. Louis, Missouri

We review demographic and mental health data from 1,729 youths aged 13 to 24 who attended the SPOT (Supporting Positive Opportunities with Teens), a free multi-resource drop-in youth center in St. Louis, within an 18-month period. Logistic regression analysis showed an association of increased mental health utilization and younger age, male gender, unemployment, lower educational attainment, having Medicaid, drug problems, and HIV positive status. Decreased mental health utilization was associated with black or mixed ethnicity, and living with a roommate.

Racial and ethnic service use disparities among homeless adults with severe mental illnesses receiving ACT

OBJECTIVE

Case management-based interventions aimed at improving quality of care have the potential to narrow racial and ethnic disparities among people with chronic illnesses. The aim of this study was to assess the equity effects of assertive community treatment (ACT), an evidence-based case management intervention, among homeless adults with severe mental illness.

METHODS

This study used baseline, three-, and 12-month data for 6,829 black, Latino, and white adults who received ACT services through the ACCESS study (Access to Community Care and Effective Services and Support). Zero-inflated Poisson random regression models were used to estimate the adjusted probability of use of outpatient psychiatric services and, among service users, the intensity of use. Odds ratios and rate ratios (RRs) were computed to assess disparities at baseline and over time.

RESULTS

No disparities were found in probability of use at baseline or over time. Compared with white users, baseline intensity of use was lower for black users (RR=.89; 95% confidence interval [CI]=.83-.96) and Latino users (RR=.65; CI=.52-.81]). Intensity did not change over time for whites, but it did for black and Latino users. Intensity increased for blacks between baseline and three months (RR=1.11, CI=1.06-1.17]) and baseline and 12 months (RR=1.17, CI=1.11-1.22]). Intensity of use dropped for Latinos between baseline and three months (RR=.83, CI=.70-.98).

CONCLUSIONS

Receipt of ACT was associated with a reduction in service use disparities for blacks but not for Latinos. Findings suggest that ACT's equity effects differ depending on race-ethnicity.

Impact of hepatitis B and C infection on health services utilization in homeless adults: a test of the Gelberg-Andersen Behavioral Model for Vulnerable Populations

OBJECTIVE

Homeless people have disproportionately high rates of viral hepatitis. The Gelberg-Andersen Behavioral Model for Vulnerable Populations (predisposing, enabling, and need variables) was expanded to predict prevalence and awareness of hepatitis B (HBV) or hepatitis C (HCV) infection, as well as health services utilization (HSU) among homeless adults using structural equation modeling.

DESIGN

A population-based sample of 534 homeless adults in Los Angeles' "Skid Row" was interviewed and tested for HBV and HCV.

MAIN OUTCOME MEASURES

Main outcome measures included HBV/HCV seropositivity, awareness of seropositivity, and HSU in the previous 12 months.

RESULTS

Seropositivity (43%), usually unknown (72% of seropositives), was predicted by injection drug use, alcohol use, older age, and risky sexual behavior. No regular source of care, risky sexual behavior, less case management, and greater age predicted not knowing one's positive status. Health insurance, younger age, alcohol use, perceived bad health and more medical conditions predicted emergency room (ER) use; ER use was less likely among seropositives. Hospitalizations were predicted by more medical conditions and greater percentage of life homeless and were less frequent among African Americans and males. Ambulatory visits were predicted by a regular source of care, case management, more education and perceived bad health; they were less likely among seropositives.

CONCLUSION

The Gelberg-Andersen Behavioral Model provided a useful guide for predicting HBV/HCV positivity as well as HSU in homeless adults. Most hepatitis-positives did not know their status and used health services less often than other homeless adults. More aggressive detection of hepatitis B and C among homeless adults is needed.

Are There Racial Ethnic Differences in Indigent, Inner-City Clients With Dual-Diagnosis?

OBJECTIVE: An exploratory, cross-sectional study examined personal, clinical, and treatment characteristics among non-Hispanic Caucasian, non-Hispanic African American, and Hispanic indigent, inner-city clients with co-occurring disorders. METHODS: Men and women, 20-50 years old who met DSM-IV criteria for concurrent mood and substance use disorders were eligible. Inpatients, persons in detoxification programs, or incarcerated inmates were excluded. Assessments covered sociodemographic characteristics, clinical diagnoses, substance use, psychosocial variables, health care utilization and treatment history. RESULTS: Two hundred volunteers were screened, and 145 were eligible to enroll. Racial ethnic group differences in the distribution of mood and substance use disorders and medical diseases were evident. Receiving psychiatric treatment and psychiatric medications significantly differed among racial ethnic groups with Caucasians more likely to receive these services than African Americans or Hispanics. African Americans and Hispanics were also more likely than Caucasians to test positive for their drug of choice and for other drugs as well. Serious medical illnesses were evident in about half of the sample, and the distributions of these illnesses significantly differed among racial ethnic groups. There were no significant differences in hospitalization or emergency room visits among racial ethnic groups. CONCLUSIONS: Indigent, inner-city clients have multiple psychiatric and medical problems that warrant continuity of care. However, few doctor's visits for medical illnesses, lack of psychotropic medications, staggering unemployment, and homelessness were common in our sample. These results present healthcare and social service professionals with potentially serious treatment challenges. Better recognition and understanding of racial ethnic needs in those with co-occurring disorders are needed.
