Aging homeless persons have been largely neglected in the gerontological and homeless literature. This article presents an overview of homelessness and aging within the context of a testable, provisional model for explaining homelessness in this population. The author proposes 16 individual and 5 structural and programmatic variables that contribute to the etiology and sustenance of homelessness among aging persons.
OBJECTIVE: Networks of agencies at the 18 demonstration sites in the Access to Community Care and Effective Services and Supports (ACCESS) program for homeless persons with serious mental illness were surveyed to profile baseline levels of systems performance and integration as part of a longitudinal evaluation of systems change and client outcomes. METHODS: Interviews were conducted with a representative from each of 875 agencies in the 18 service networks. Information was obtained about the perceived performance of the service system and the extent of systems integration as measured by client referrals, funds exchanges, and information sharing between agencies. Measures consisted of two multi-item scales assessing the accessibility and coordination of services for the target population in each community and four indexes of interagency relationships. RESULTS: Services at baseline for homeless mentally ill persons at the program sites were rated as relatively inaccessible, and the coordination of services between agencies was rated as even more problematic. Interagency ties were largely based on client referrals and information exchanges, with very few instances of funding transfers in the form of contracts or grants. On average, at baseline agencies that had received an ACCESS grant were better connected to their local service network than were other agencies. CONCLUSIONS: Consistent with the premise of the ACCESS demonstration, services for persons who are homeless and mentally ill in urban America are fragmented and not very accessible. The longitudinal design of the evaluation will allow for an assessment of efforts to improve services and systems integration and of the effects of these improvements on client outcomes.
OBJECTIVE: The effectiveness of two types of service programs in ameliorating homelessness among individuals with severe mental illness was compared. METHODS: Homeless persons with severe mental illness were recruited into the study on their entry into one of two types of homeless service programs. The first was a comprehensive housing program, in which consumers received guaranteed access to housing, housing support services, and case management. The second was a program of case management only, in which consumers received specialized case management services. In a quasi-experimental or nonrandom-assignment design, participants responded to instruments measuring housing status, mental health symptoms, substance use, physical health, and quality of life at baseline (program entry) and at six months and 12 months after entry. The baseline interview was completed by 152 participants and at least one of the two follow-up interviews by 108 participants. High-, medium-, and low-impairment subgroups, based on psychiatric symptoms and degree of alcohol and illegal drug use, were formed by means of a propensity score subclassification. RESULTS: Persons with high psychiatric symptom severity and high substance use achieved better housing outcomes with the comprehensive housing program than with case management alone. However, persons with low and medium symptom severity and low levels of alcohol and drug use did just as well with case management alone. CONCLUSIONS: The results suggest that the effectiveness, and ultimately the cost, of homeless services can be improved by matching the type of service to the consumer's level of psychiatric impairment and substance use rather than by treating mentally ill homeless persons as a homogeneous group.
OBJECTIVE: This study measured the impact of an assertive case management program for psychiatrically disabled homeless persons in metropolitan Toronto. It was hypothesized that the program would improve residential stability, reduce psychiatric symptoms, improve social functioning, improve social networks, and increase use of appropriate services. METHOD: For 59 clients admitted to the program, assessments for the nine-month period before program entry were completed and were repeated nine months later. The Brief Psychiatric Rating Scale and a version of the Scale for Level of Functioning were the main measures of outcome. RESULTS: At follow-up significant improvements in residential stability and reductions in psychopathology were demonstrated. Improvements in social functioning and increases in social network size were significant. Although no baseline data about service use were collected, clients used basic support services during their first nine months in the program. CONCLUSIONS: The success of the program demonstrates that a difficult-to-treat patient population can be helped in a humane fashion if trained personnel are available.
PURPOSE: To investigate whether substance abuse is a direct factor in the explanation of homelessness or one that operates indirectly through disaffiliation and human capital processes to place individuals at greater risk of the condition. METHODS: Analyses were conducted using data on substance abuse and homeless experiences from a random probability sample of 481 homeless persons and those at risk of homelessness in Cook County, Illinois. Covariance structure models were used to assess substance abuse, human capital, and disaffiliation as potential precursors of homelessness, with particular attention paid to the direct and indirect role of substance abuse in the loss of domicile. RESULTS: Analysis of several nested models of homelessness links substance abuse only indirectly to loss of domicile, primarily through its impact on social and institutional affiliations. Contrary to expectations, substance abuse did not impact homelessness indirectly by diminishing the accumulation of human capital. CONCLUSIONS: The role of disaffiliation as a proximate cause of homelessness was confirmed. This locates the phenomenon within the context of society itself, as a direct result of a breakdown in the social bonds necessary for human community. Substance abuse plays a critical role in this breakdown, negatively influencing social as well as institutional relationships.
Gender differences in health risks and symptoms are compared for a survey sample of 100 homeless persons and for the general population. Homeless men appear at greater risk of exhibiting symptoms. Nonetheless, homeless women report more symptoms, a result consistent with general population trends. Predisposing illnesses were the most accurate predictors of the number of reported symptoms, but gender explained a significant amount of variation in reported symptoms after other health risks were controlled. The findings inform the debate on the relative importance of biological factors, acquired risks, illness perception and behavior, and reporting bias in explaining why women report more symptoms in survey research. It appears likely that female reporting bias and gender differences in illness perception are underestimated in general population surveys because even under extreme conditions, men are less likely than women to report symptoms.
Not much is known about the state of oral and dental health of homeless and vagrant people in Montreal. However, a study conducted during April 1993, in conjunction with dental health month, has made it possible to undertake a better evaluation of their oral health status and to identify ways of making dental treatment available to them. Once the oral health status of this population is known, the official body responsible for homeless and vagrant individuals, the "Régie régionale Montréal-Centre," can be given possible solutions for their treatment and care. Most of the homeless are welfare recipients and have access to some basic benefits from this source. One of these benefits is free access to all assured basic dental services. These services are available after a six-month waiting period, and are provided by a dentist of the homeless person's choice. At the beginning of this study, the authors hypothesized that homeless people would prefer to be treated in the hostels and shelters where they sleep, which is currently the situation in Boston. But in 65 per cent of cases, their responses to a questionnaire administered as part of this study were quite different, and indicated that they would prefer to visit a private dentist of their choice. However, there is another important group (35 per cent) who wish to receive dental treatment in the hostels they presently frequent. Any proposed solution should take into consideration both groups of homeless and vagrant persons.
GOALS: To determine the prevalence of and risk factors for dyspepsia in a representative sample of homeless persons using shelters in Toronto, Canada. BACKGROUND: Homeless people have many risk factors for dyspepsia, but little information is available on gastrointestinal symptoms in this population. STUDY: Cross-sectional survey of a representative sample of 100 homeless adults, with serologic testing for Helicobacter pylori infection. RESULTS: The prevalence of moderate, severe, or very severe symptoms within the past 3 months was 18% for upper stomach pain and 59% for any dyspeptic symptom. Nonwhite ethnicity (odds ratio, 3.5; 95% confidence interval, 1.1-10.9) and a history of gastrointestinal disease (odds ratio, 8.6; 95% confidence interval, 2.5-29.6) were significantly associated with moderate to very severe upper stomach pain. H. pylori infection was identified in 31% of participants but was not significantly associated with dyspepsia. CONCLUSIONS: Dyspepsia is a common problem among homeless adults in Toronto. The presence of upper stomach pain is most strongly associated with a history of gastrointestinal disease.
The Institute of Medicine has placed a priority on determining the special health-care needs of elderly homeless persons. As part of a community-based study of 521 homeless adults in two beach communities of Los Angeles, we compared the demographic characteristics and health of older (age rangek 50-78, n = 61) and younger (age range, 18-49, n = 460) homeless individuals. Compared with younger adults, older adults were more likely to be white (85% versus 61%), veterans (59% versus 27%), retired (36% versus 3%), and living in a vehicle (21% versus 8%). Older adults were more likely to report having a chronic disease (69% versus 49%), functional disabilities, no informal social contacts during the previous month (49% versus 27%), observed high blood pressure (42% versus 22%), elevated creatinine (11% versus 2%), and elevated cholesterol (57% versus 36%). Older adults were less likely to have a toothache (3% versus 30%), report psychotic symptoms (25% versus 42%), and to be illegal drug users (15% versus 55%). Although they are chronologically younger, the constellation of health and functional problems of older homeless adults resemble those of geriatric persons in the general population. We suggest that geriatricians could play a significant role in training other primary-care providers to evaluate and treat socially isolated older homeless adults in a more comprehensive way than is currently standard in practice (e.g., interdisciplinary team care and emphasis on functional status, rehabilitative medicine, and assessment for sensory impairment).
BACKGROUND: From 1978 through 1992, the number of patients with tuberculosis in New York City nearly tripled, and the proportion of such patients who had drug-resistant isolates of Mycobacterium tuberculosis more than doubled. METHODS: We reviewed, confirmed, and analyzed data obtained during the surveillance of patients with tuberculosis. RESULTS: From 1992 through 1994, there was a 21 percent decrease in reported cases of tuberculosis in New York City. An evaluation of the surveillance system revealed very few unreported cases. The number of cases decreased by more than 20 percent among blacks and Hispanics, persons with documented human immunodeficiency virus infection, homeless persons, and patients with multidrug-resistant tuberculosis; in all these groups, tuberculosis is likely to result from recent transmission. In contrast, the number of cases of tuberculosis increased among elderly and foreign-born persons, in whom the disease is likely to result from the reactivation of an infection acquired many years earlier. Enrollment in a program of directly observed therapy, in which health workers watch patients take their medications, increased from fewer than 100 patients to nearly 1300, with more than 32,000 patient-months of observation from 1992 through 1994. CONCLUSIONS: Epidemiologic patterns strongly suggest that the decrease in cases resulted from an interruption in the ongoing spread of M. tuberculosis infection, primarily because of better rates of completion of treatment and expanded use of directly observed therapy. Another contributing factor may have been efforts to reduce the spread of tuberculosis in institutional settings, such as hospitals, shelters, and jails. Expansion of measures to prevent and control tuberculosis and support of international control efforts are needed to ensure continued progress.
To make appropriate treatment and public policy recommendations to address the problems of homeless mentally ill persons, it is important to differentiate the homeless mentally ill population from the homeless population in general. Effective advocacy for homeless mentally ill persons should have realistic goals that address the specific needs of that population rather than attempt to change the basic problems of society. The effective advocacy that has secured services for developmentally disabled persons can serve as a model. Mental health professionals' limited response to the problems of homeless mentally ill persons has further stigmatized mentally ill persons in general; one of the most powerful actions mental health professionals could take to fight stigma would be to help provide treatment and residential alternatives for homeless mentally ill persons. The recommendations of both the first and the second American Psychiatric Association task forces on the homeless mentally ill are discussed.
Data were collected from 88 homeless persons in Port-of-Spain, Trinidad to assess HIV risk. 68% of the sample were engaging in unprotected sex with multiple partners, 25% were exchanging sex for money, and 29.5% were regularly smoking crack cocaine. Many had two or more of these behaviours that put them at high risk of HIV infection. Females were significantly more likely to be sex traders, to engage in bisexual behaviour and to have a history of psychiatric illness. The relationship between psychiatric illness and HIV risk behaviours among homeless female persons is explored. Educational interventions are suggested to reduce the public health risks in this population.
The identification of homelessness as a national problem has focused attention on defining the needs of this sizable population. Existing studies on the medical problems of the homeless are largely descriptive and are limited by lack of comparison to nonhomeless persons. To help fill this gap in knowledge, we conducted a retrospective study of the medical problems of homeless and nonhomeless persons cared for in an outpatient clinic serving the medically indigent. Homeless persons (n = 150) were more likely to be identified as alcoholic and to be seen for cuts and gynecologic problems than nonhomeless persons (n = 154) (p less than .01). There were no significant differences in the occurrence of other illnesses considered to be prevalent in the homeless. This study is among the first that validates descriptive data on the health problems of homeless persons by using concurrent nonhomeless controls. It may help in designing programs to meet the medical needs of the homeless.
A follow-up study that tracked a sample of 133 people released from a state mental hospital showed that 35 percent became homeless within three months, supporting the theory that deinstitutionalization contributes to homelessness. An in-depth, qualitative tracking procedure provides data to describe key characteristics of the homeless person and the process by which people become homeless. These data point to solutions for improved care of severely mentally disabled people for whom the aftercare system has failed.
Outreach is a treatment modality for engaging underserved populations in health care. Nowhere is outreach more relevant than in delivering services to homeless persons with mental illness. Programs providing outreach to homeless people have been in existence for at least two decades and a craft has developed naturalistically. However, there has been insufficient formal examination of factors that influence the effectiveness of outreach and how it is actually performed. The authors present an in-depth examination of issues related to outreach to the homeless. They review different outreach modalities, the role of the individual clinician, and the art of teamwork. They also discuss external issues such as financing, access to housing, interactions with other professions, and working conditions. The authors conclude with a brief discussion concerning the application of outreach to populations other than homeless individuals with psychiatric disorders and suggest future directions for improving our understanding of this important modality.
BACKGROUND: New federal initiatives target funds toward chronically homeless as distinct from other homeless persons. Few data exist, however, to substantiate the implications of chronic homelessness for major health outcomes. OBJECTIVES: Using data from a 2-year cohort of addicted persons, we tested whether changes in mental and physical health-related quality of life (HRQOL) differed according to homeless chronicity. METHODS: Using self-reported homelessness, we classified subjects as chronically homeless (CH; n = 60), transitionally homeless (TRANS; n = 108), or as housed comparison subjects (HSD; n = 106). The Short Form-36 Health Survey, administered at baseline and 2 follow-ups over a period of 2 years, provided a Mental Component Summary (MCS) and a Physical Component Summary (PCS) for HRQOL. Mixed model linear regression was used to test the association between housing status, MCS, and PCS. Additional models assessed whether medical, psychiatric, addiction, and social support measures could account for HRQOL differences. RESULTS: All subjects had low MCS scores at study entry (mean, 31.2; SD, 12.6). However, there was a significant housing status-by-time interaction (P = 0.01). At final follow-up, CH and TRANS subjects had lower adjusted MCS scores than HSD subjects (33.4, 38.8, and 43.7 for the 3 groups, respectively; all P < or = 0.01). By contrast, housing status and PCS were not significantly associated (P = 0.19). Medical, psychiatric, addiction, and social support variables had significant associations with MCS, and their inclusion in the regression reduced the apparent effect of housing status on MCS. CONCLUSIONS: Chronic homelessness was associated with especially poor mental but not physical HRQOL over time. These findings reinforce a new typology of homelessness.
Homeless people eat foods at municipal and charity run shelters, fast-food restaurants, delicatessens, and from garbage bins. Data on the adequacy of the diets and the nutritional status of homeless persons are sparse. Therefore, nutritional indicators of 55 urban homeless subjects were assessed, and a high prevalence of risk factors was identified. Although 93 percent of subjects reported that they obtained enough to eat, a low dietary adequacy score of 10.1 (norm = 16) indicated that the quality of the diet was inadequate. Diet records showed a high intake of sodium, saturated fat, and cholesterol. Serum cholesterol levels above the desirable limit of 200 mg per dl were prevalent. Anthropometric measurements were significantly different from percentile distributions of the U.S. population (P less than .001). Triceps skinfold measurement was above the 95th percentile in 25 percent of subjects. Upper arm muscle area, which reflects lean body mass, was below the 5th percentile in 23.3 percent of women and 44 percent of the men. These decreased levels of lean body mass and increased levels of body fat, together with the elevated serum cholesterol levels and the shortages of essential nutrients in the diet, may place the homeless at risk of developing nutrition-related disorders.
Investigations of homelessness have been hampered by the lack of operational definitions sensitive enough to achieve subgroup differentiation and simple enough to permit replication. As a consequence, programming and policy development have often proceeded based on varying assessments of the composition, size, and needs of the homeless population. This paper describes the empirical use of duration of homelessness and dwelling place as elements of an operational definition of homelessness. The approach reflects a conceptualization of homelessness as a continuous variable that can be described by coordinates of time and place. A screening instrument that quantified the homeless experience was developed and evaluated in conjunction with a federally funded demonstration project for homeless substance-abusing men and women. Eight hundred and thirty-nine men and women from six public detoxification centers were screened over a two-year period that began in August 1988. Respondents were asked eight questions to assess duration (time) and location (place) of homelessness before they entered the detoxification center. A simple index was constructed retrospectively and found to differentiate the sample into homeless and near-homeless subgroups. Between-group differences were statistically significant in demographics, presenting problems, and probability for successful intervention. These data paralleled previously reported differences between homeless subgroups and support the concurrent validity of the index. Cronbach's alpha (.72) showed the index to be moderately reliable. Differentiation of homeless persons into meaningful subgroups appears possible and programmatically recommended. Homelessness is not a unitary phenomenon, and it is unlikely to respond to therapeutic interventions that fail to consider individual differences.
