Street children in South Africa: findings from interviews on the background of street children in Pretoria, South Africa.

In the present study findings from interviews on the background of street children in Pretoria, South Africa are presented, discussed, and compared with research done in the past on South African street children. Findings from the investigation indicate that the average age of South African street children is approximately 13 years, predominantly of male African origin. Most have been on the streets for three years or longer, and they cited family violence, parental alcoholism, abuse, and poverty as the main motivating factors for leaving home. Most of these findings are common among street children all over the world.

Projection of HIV infection in Calcutta.

Starting with the base year of 1991, the HIV infection projection for 1992-99 for the total, as well as various high-risk sub-populations of Calcutta, the first of its kind is provided. These projections are based on statistical methodology developed in this paper. Our methodology for spread of HIV infection takes into account various social interactions and practices and also uses available data. Rates of these interactions and practices and estimates of demographic parameters used in making projections were obtained primarily from surveys and census data. Since one of these estimated rates, that of HIV transmission rate through heterosexual encounters between an infected and an uninfected had a large range, we have provided two sets of projections based on the largest of these rates (worst-case scenario) and another that is consistent with the available data. The total projection of the number of HIV infected cases in Calcutta for 1999 is between 49,000 and 1,26,000. Separate projections are also provided for high-risk sub-groups. Among these, the sex workers expectedly will continue to manifest the highest numbers of newly infected cases. The temporal rate of increase in prevalence is projected to be alarmingly higher in the general population than even among sex workers, although the actual prevalence will continue to be the lowest in the general population compared to all other sub-groups of the population.

Self-identified health concerns of two homeless groups.

A number of conclusions can be drawn from the themes derived from the interview data. First, even though the most basic physical needs, such as food, clothing, and shelter were being met, a recurring theme from the responses of the homeless was the need for interaction with a caring person. The feeling that no one cares, a lack of self-worth, and a sense of limited control over their lives may lead to depression, hopelessness, and finally illness. The extent and effectiveness of health-seeking behaviors among this group are limited because of decreased trust, decreased motivation for self-care, and isolation from social and health care systems. Second, if health needs are to be met, services must be provided in sites where they can be accessed by the homeless. For transients, health care services may be provided most effectively through the shelters. For the SRO residents, these services could be provided through a combination of clinics in hotel lobbies and visits to rooms. Third, developing trust with the homeless includes meeting their self-perceived basic needs. What may seem like nonnursing activities, such as fixing a meal, may be important in establishing rapport with SRO residents. If a nurse assists a homeless person to meet survival needs, that person may be more willing to deal with health issues. Fourth, the population is highly heterogeneous. Each subgroup has its own identity. Most SRO residents do not want to be identified with street people, even through a portion of them move between street life and SRO life. Health care professionals need to recognize these differences, accept the life-style of each subgroup, and respect each homeless person as a unique individual. Finally, caring is the primary element necessary in providing nursing services to the homeless. Awareness and understanding of the homeless way of life will increase nurses' effectiveness in working with this ever growing population.

Association between time homeless and perceived health status among the homeless in San Francisco.

The purpose of this study was to describe the perceived health of the homeless, and to measure the effect of time homeless on perceived health status, after controlling for sociodemographic characteristics and health conditions. The design was cross-sectional; the population was a representative sample of homeless in San Francisco, interviewed on health issues. Analysis of predictors of poor or fair health status was by logistic regression. In this sample of 2780 persons, 37.4% reported that their health status was poor or fair as compared to good or excellent. Reporting poor or fair health status was significantly associated with time homeless, after controlling for sociodemographic variables and health problems including results from screening for HIV and TB (OR = 1.49, 95% CI 1.24-1.79). Comparisons with data from the National Health Interview Survey (NHIS) showed poorer health status among the homeless persons in this study. Standardized morbidity ratios were highest for asthma; there was twice the number of homeless persons reporting asthma, in younger as well as older adults, as would be expected using NHIS rates. There was also an excess of arthritis, high blood pressure and diabetes in those age 18-44 as compared to adults in the Health Interview Survey. The time spent homeless remains associated with self-reported health status, after known contributors to poor health are controlled. Persons who have been homeless for longer periods of time may be the persons to whom health care interventions should be aimed.

The Behavioral Model for Vulnerable Populations: application to medical care use and outcomes for homeless people.

OBJECTIVES: (1) To present the Behavioral Model for Vulnerable Populations, a major revision of a leading model of access to care that is particularly applicable to vulnerable populations; and (2) to test the model in a prospective study designed to define and determine predictors of the course of health services utilization and physical health outcomes within one vulnerable population: homeless adults. We paid particular attention to the effects of mental health, substance use, residential history, competing needs, and victimization. METHODS: A community-based probability sample of 363 homeless individuals was interviewed and examined for four study conditions (high blood pressure, functional vision impairment, skin/leg/foot problems, and tuberculosis skin test positivity). Persons with at least one study condition were followed longitudinally for up to eight months. PRINCIPAL FINDINGS: Homeless adults had high rates of functional vision impairment (37 percent), skin/leg/foot problems (36 percent), and TB skin test positivity (31 percent), but a rate of high blood pressure similar to that of the general population (14 percent). Utilization was high for high blood pressure (81 percent) and TB skin test positivity (78 percent), but lower for vision impairment (33 percent) and skin/leg/foot problems (44 percent). Health status for high blood pressure, vision impairment, and skin/leg/foot problems improved over time. In general, more severe homeless status, mental health problems, and substance abuse did not deter homeless individuals from obtaining care. Better health outcomes were predicted by a variety of variables, most notably having a community clinic or private physician as a regular source of care. Generally, use of currently available services did not affect health outcomes. CONCLUSIONS: Homeless persons are willing to obtain care if they believe it is important. Our findings suggest that case identification and referral for physical health care can be successfully accomplished among homeless persons and can occur concurrently with successful efforts to help them find permanent housing, alleviate their mental illness, and abstain from substance abuse.

Mental illness among homeless individuals in a suburban county.

OBJECTIVE: This paper compares the prevalence of mental illnesses and alcohol and drug abuse and the residential histories of homeless individuals identified as having a mental illness and individuals who are not so identified. The cohort consisted of single persons applying for shelter over a 12-week period in Westchester County, a suburban county in New York State. METHODS: The sample of 201 persons (89 percent male, with a mean age of 37) represented 77 percent of consecutive single shelter applicants in a single-point-of-entry system over the study period. Information from an intake assessment was augmented by a semistructured interview to reconstruct subjects' residential history for the last five years, including periods of homelessness and time in institutions. RESULTS: Twenty-one percent of the cohort was classified as having mental illness. Seventy-two percent had a diagnosis of drug abuse or dependence, and 51 percent had alcohol abuse or dependence. For individuals with a mental illness, the use of cocaine and heroin was significantly lower, but alcohol use was somewhat greater, compared with other homeless persons. Persons with mental illness also experienced homelessness of some kind over a significantly longer period (a mean of seven years versus a mean of three years for other subjects), and they spent almost twice as many weeks during the previous five years literally homeless. Institutional time, most of which consisted of time in jail or prison, was equivalent for both groups. CONCLUSIONS: Not only is residential instability heightened among shelter users with mental illness, but over time public institutions play a critical role in their accommodations. For some homeless persons with mental illness, the circuit of shelters, rehabilitation programs, jails, and prisons may function as a makeshift alternative to inpatient care or supportive housing and may reinforce the marginalization of this population.

Recruitment and retention of homeless mentally ill participants in research.

Are the unstable residential and personal lives of homeless mentally ill (HMI) individuals so difficult as to preclude their inclusion in rigorous, longitudinal research protocols? The continued presence of HMI individuals in U.S. society has prompted the mental health research community to reconsider the question of whether clinical trial and demonstration research protocols are feasible with this population. This article briefly examines the existing research literature on recruitment and retention rates in recent studies of this population and, in more detail, the specific strategies used by researchers to recruit and retain HMI individuals as research participants. In general, with sufficient resources and the persistent use of existing strategies for recruitment and retention, HMI individuals can be successfully studied over time. Finally, to demonstrate this potential, the recruitment and retention strategies of the San Diego McKinney Homeless Mentally Ill Demonstration Research Program are described.

Emergency department use among the homeless and marginally housed: results from a community-based study.

OBJECTIVES: This study examined factors associated with emergency department use among homeless and marginally housed persons. METHODS: Interviews were conducted with 2578 homeless and marginally housed persons, and factors associated with different patterns of emergency department use were assessed in multivariate models. RESULTS: Findings showed that 40.4% of respondents had 1 or more emergency department encounters in the previous year; 7.9% exhibited high rates of use (more than 3 visits) and accounted for 54.5% of all visits. Factors associated with high use rates included less stable housing, victimization, arrests, physical and mental illness, and substance abuse. Predisposing and need factors appeared to drive emergency department use. CONCLUSIONS: Efforts to reduce emergency department use among the homeless should be targeted toward addressing underlying risk factors among those exhibiting high rates of use.

Health care utilization among homeless adults prior to death.

This study characterizes health care utilization prior to death in a group of 558 homeless adults in Boston. In the year before death, 27 percent of decedents had no outpatient visits, emergency department visits, or hospitalizations except those during which death occurred. However, 21 percent of homeless decedents had a health care contact within one month of death, and 21 percent had six or more outpatient visits in the year before death. Injection drug users and persons with HIV infection were more likely to have had contact with the health care system. This study concludes that homeless persons may be underusing health care services even when they are at high risk of death. Because a subset of homeless persons had extensive health care contacts prior to death, opportunities to prevent deaths may have been missed, and some deaths may not have been preventable through medical intervention.

Human immunodeficiency virus infection among homeless men in a New York City shelter. Association with Mycobacterium tuberculosis infection.

The human immunodeficiency virus (HIV) seroprevalence among a selected sample of 169 high-risk homeless men residing in a congregate shelter in New York City, NY, was 62%. Seropositivity for HIV correlated significantly with intravenous drug use (odds ratio, 3.3; 95% confidence interval, 1.4 to 4.4) and active tuberculosis (odds ratio, 7.0; 95% confidence interval, 3.4 to 13.5). Most cases of active tuberculosis were among homeless men with acquired immunodeficiency syndrome (AIDS) or AIDS-related complex; and significant CD4 lymphocyte depletion was associated with active tuberculosis. Total time homeless correlated positively with active and latent tuberculosis infection. Compliance rates with return for HIV antibody test results, medications, and follow-up visits were 70%, suggesting a significant degree of knowledge, awareness, and personal concern regarding HIV infection among homeless men; yet 28% of homeless intravenous drug users continue active drug injection, despite HIV infection. Cohabitation in overcrowded congregate dormitories creates a risk of airborne transmission of tuberculosis, which is a common reactivation infection in HIV-seropositive homeless men. Medically appropriate housing should be provided to such homeless persons, and expanded HIV antibody testing, counseling, and medical services on site should be offered to residents of shelters.

Civil commitment viewed from three perspectives: professional, family, and police.

This study was designed to uncover differences in interpretation and implementation of civil commitment laws. Such problems in interpretation may contribute to mentally ill persons remaining untreated and potentially joining the thousands of homeless mentally ill persons in our communities or the incarcerated mentally ill persons in our prisons and jails. The study examines differences in the assessments of the severity of mental illness, and the appropriateness and judged feasibility for commitment in different commitment categories, made by emergency room admitting personnel, police officers, and families of mentally ill persons. The results demonstrate that police are significantly less likely than families or mental health professionals to perceive mental disability or a need for involuntary commitment on any grounds. Professional psychiatric staffs were much more likely than the other two groups to consider commitment in all three cases as legally feasible. Family ratings of appropriateness for commitment based on the presented symptomatology are similar to those of professionals. However, they are significantly less likely than professionals to judge the cases as legally feasible for commitment, and they interpret the laws similarly to the police raters in believing that commitment laws will not allow involuntary hospitalizations. Consequences and implications of these differences are discussed.

Short versus longer term effectiveness of an outreach program for the homeless mentally ill.

Presents 12-month follow-up results from an outreach/linkage intervention with persons who are homeless and mentally ill, contrasting these with results obtained at 4 months. Both sets reflect the success of the program in placing individuals in independent housing. However, longer term data provide useful information regarding client movement patterns and increased tenure in nonhomeless living arrangements beyond the termination of specialized services. Analyses of 12-month residential outcomes identified four variables as significant predictors: recruitment source, project service duration, CMH service duration, and client age. In contrast to 4-month predictors, variables reflecting baseline client functioning were no longer significantly related to outcome, suggesting that the positive effects of the intervention may take longer to achieve with some clients. Discussion focuses on the implications of these effectiveness results for future research designs and measures as well as the utility and limitations of preexperimental approaches for evaluating innovative service models when implementation and efficacy experiences are lacking.

Are jails replacing the mental health system for the homeless mentally ill?

The author explores the process of how homeless mentally ill persons become involved with the criminal justice system. The unique demands of homelessness and chronic mental illness were specifically examined in this naturalistically based study. The author concludes that a combination of severe mental illness, a tendency to decompensate in a nonstructured environment, and an inability or unwillingness to follow through with aftercare contributed to involvement with the criminal justice system. Changes in the mental health system that would prevent the criminalization of the homeless mentally ill are suggested.

Tenant outcomes in supported housing and community residences in New York City.

OBJECTIVE: This study examined whether outcomes in housing, clinical status, and well-being of persons with severe mental illness and a history of homelessness differ between those in supported housing and those in community residences, two housing arrangements that substantially differ in the level of independence that is offered to its tenants. METHODS: A quasi-experimental 18-month follow-up study was conducted with 157 persons newly entering supported housing and community residences. The housing models accepted persons with similar illness characteristics and homelessness histories, so that the inability to randomly assign tenants to housing types could be compensated for by propensity scoring methods. Tenure in housing was examined by using survival models. Analyses of other outcomes used hierarchical linear and regression models in both intent-to-treat (N=139) and true-stayer (N=80) analyses. RESULTS: Tenure in housing did not differ by housing type. Substantial proportions of tenants in both models remained housed during the follow-up period. Tenants in supported housing reported greater housing satisfaction in terms of autonomy and economic viability. Over time some tenants in supported housing reported greater feelings of isolation. Independent of housing type, symptoms of depression or anxiety at housing entry increased the risk of poorer outcomes. CONCLUSIONS: The models of supported housing were viable portals of entry into community housing for homeless persons, even for consumers with characteristics indicating that they would have been more likely to be placed in community residences. The results suggest that greater clinical attention should be paid to persons who exhibit depression or anxiety when entering housing.

Risk of death among homeless women: a cohort study and review of the literature.

BACKGROUND: Homeless people are at high risk for illness and have higher death rates than the general population. Patterns of mortality among homeless men have been investigated, but less attention has been given to mortality rates among homeless women. We report mortality rates and causes of death in a cohort of women who used homeless shelters in Toronto. We also compare our results with those of other published studies of homeless women and with data for women in the general population. METHODS: A cohort of 1981 women not accompanied by dependent children who used homeless shelters in Toronto in 1995 was observed for death over a mean of 2.6 years. In addition, we analyzed data from published studies of mortality rates among homeless women in 6 other cities (Montreal, Copenhagen, Boston, New York, Philadelphia and Brighton, UK). RESULTS: In Toronto, mortality rates were 515 per 100,000 person-years among homeless women 18-44 years of age and 438 per 100,000 person-years among those 45-64 years of age. Homeless women 18-44 years of age were 10 times more likely to die than women in the general population of Toronto. In studies from a total of 7 cities, the risk of death among homeless women was greater than that among women in the general population by a factor of 4.6 to 31.2 in the younger age group and 1.0 to 2.0 in the older age group. In 6 of the 7 cities, the mortality rates among younger homeless women and younger homeless men were not significantly different. In contrast, in 4 of the 6 cities, the mortality rates were significantly lower among older homeless women than among older homeless men. INTERPRETATION: Excess mortality is far greater among homeless women under age 45 years than among older homeless women. Mortality rates among younger homeless women often approach or equal those of younger homeless men. Efforts to reduce deaths of homeless women should focus on those under age 45.

Self-reported comorbidities, perceived needs, and sources for usual care for older and younger homeless adults.

BACKGROUND: While older individuals who are homeless tend to be in poorer health, it is less clear how they view their health care needs and whether their self-reported patterns for accessing health services differ from younger homeless counterparts. METHODS: Cross-sectional, community-based survey of homeless adults in Pittsburgh and Philadelphia using face-to-face interviews from population proportionate sampling of sites and random sampling of subjects. Survey questions included physical and mental health comorbidities, self-reported health care, social services and personal needs, means of economic support, and sources for usual health care. For analysis purposes, respondents were grouped by age 18 to 49 years old and 50 years old or older. RESULTS: Overall, 531 adults were interviewed, with 74 respondents 50 years old or older (13.9%). Older homeless persons were 3.6 times more likely to report a chronic medical condition, 2.8 times more likely to have health insurance, and 2.4 times more likely to be dependent on heroin than homeless persons less than 50 years old. However, they also tended to use shelter-based clinics and street outreach teams more commonly as their source of usual care (20.9% vs 10.6%, P=.02) and were significantly less likely to report a need for substance abuse treatment despite high rates of abuse. CONCLUSION: Older homeless adults have a greater disease burden than their younger counterparts. However, it is unclear whether these needs are being appropriately identified and met. There is a need for specific and targeted outreach to connect them to appropriate services.

The homeless visit: enhancing residents' understanding of patients who are homeless.

BACKGROUND: With their interest in providing continuous, comprehensive care, family physicians are well-suited to treat persons who are homeless. Yet family practice residents most frequently encounter homeless patients in crowded public hospitals where time constraints and competing philosophies of patient care create suboptimal conditions and encourage the development of cynical attitudes and behavior patterns. EDUCATIONAL INTERVENTION: To address these problems, the Department of Family Medicine at Baylor College of Medicine in Houston developed a homeless visit program in which second-year residents spent one half day at a day center for the homeless. Residents interview the center's homeless clients, address their medical and psychosocial problems, and review each client's case with a faculty physician. Residents have the opportunity to explore the underlying causes of homelessness, the impact of homelessness on clients' health and well-being, and the bureaucratic barriers that homeless individuals must overcome to regain entry into the health care system. PROGRAM EVALUATION: After the first year, the program was evaluated to assess whether its original objectives had been met. Each of the second-year residents reported that the experience had been worthwhile. They recommended that the program expand the number of half days spent with homeless patients and the ancillary personnel, equipment, and supplies available. Each of these changes has been implemented and the program continues to thrive and improve. CONCLUSION: The homeless visit serves as a successful model for resident programs willing to devote as little as a half day in a 3-year curriculum toward training residents to better understand the intricate relationship between homelessness, physical and emotional needs, and an environment that simultaneously promotes illness and hinders medical attention.
