Mortality among homeless and nonhomeless mentally ill veterans

Considering the psychological experience of amputation and rehabilitation for military veterans: a systematic review and metasynthesis of qualitative research

PURPOSE

Research highlights the differences and unique experiences of military veterans experiencing amputation compared to civilians. This review aimed to synthesise qualitative research exploring the experience of amputation and rehabilitation among existing or previous members of the military.

METHODS

A systematic search of six databases (PsycINFO, AMED, MEDLINE, CINAHL, Web of Science and Scopus) was undertaken in March 2022. The results of 17 papers reporting 12 studies published between 2009 and 2022 were synthesised using a meta-ethnographic approach to generate new interpretations reflecting the experiences of members of the military who have experienced limb loss.

RESULTS

Three themes were developed from the data: (1) Making the physical and psychological transition to life after amputation; (2) The role of the military culture in rehabilitation; and (3) The impact of relationships and the gaze of others during rehabilitation and beyond.

CONCLUSIONS

Military veterans with limb loss experience difficulties in navigating civilian healthcare systems and gaining appropriate support away from the military. Rehabilitation professionals, with psychological training or mentoring, involved in the care of military veterans following amputation could offer psychological support during the transition to civilian life and targeted therapies to veterans experiencing high levels of pain, and facilitate peer support programmes.

Ophthalmic findings in marginally housed women in a Canadian city

OBJECTIVE

To assess the prevalence and common causes of ocular pathology experienced by vulnerable women with marginalized housing and/or a history of abuse, violence, and trafficking.

METHODS

Using a stratified random sampling technique, we recruited 93 women living in 10 randomly selected women's shelters in Toronto, Canada between May and November of 2018. All English-speaking females older than the age of 18 were eligible to participate. Data on demographics, medical or ocular history, subjective visual acuity, and access to eye care were obtained. Comprehensive visual screening and dilated fundoscopy were performed for each participant.

RESULTS

The median age was 40 years (interquartile range, 30.5-54 years) and the median duration of homelessness was 8 months (interquartile range, 2.25-20.5 months); 63.4% of participants reported a history of abuse, 44.9% experienced head trauma, 15.9% experienced eye trauma, 22.5% identified as refugees, and 2.17% (2 of 92) had been victims of human trafficking. The above variables were not significantly related to vision problem severity on univariate analysis. Based on the presenting visual acuity, 27.8% of participants (95% CI [18.9-38.2]) were found to have visual impairment. Visual impairment was mainly related to refractive error (54.8% [51 of 93]), however, nonrefractive pathology was also observed. Of all the participants, 64.5% had one or more abnormal findings during the vision screening, and 40.9% needed follow-up by an ophthalmologist. Most participants (96.7%) expressed interest in accessing free eye examinations.

CONCLUSIONS

Visual impairment is highly prevalent among homeless women living in Toronto. Routine vision-screening programs present an opportunity to improve the ocular health of this vulnerable population.

Mortality by Age, Gender, and Race and Ethnicity in People Experiencing Homelessness in Boston, Massachusetts

Importance

People experiencing homelessness (PEH) face disproportionately high mortality rates compared with the general population, but few studies have examined mortality in this population by age, gender, and race and ethnicity.

Objective

To evaluate all-cause and cause-specific mortality in a large cohort of PEH by age, gender, and race and ethnicity.

Design, Setting, and Participants

An observational cohort study was conducted from January 1, 2003, to December 31, 2018. All analyses were performed between March 16, 2021, and May 12, 2022. A cohort of adults (age ≥18 years) seen at the Boston Health Care for the Homeless Program (BHCHP), a large federally funded Health Care for the Homeless organization in Boston, Massachusetts, from January 1, 2003, to December 31, 2017, was linked to Massachusetts death occurrence files spanning January 1, 2003, to December 31, 2018.

Main Outcomes and Measures

Age-, gender-, and race and ethnicity-stratified all-cause and cause-specific mortality rates were examined and compared with rates in the urban Northeast US population using mortality rate ratios (RRs).

Results

Among the 60 092 adults included in the cohort with a median follow-up of 8.6 (IQR, 5.1-12.5) years, 7130 deaths occurred. The mean (SD) age at death was 53.7 (13.1) years; 77.5% of decedents were men, 21.0% Black, 10.0% Hispanic/Latinx, and 61.5% White. The all-cause mortality rate was 1639.7 deaths per 100 000 person-years among men and 830 deaths per 100 000 person-years among women. The all-cause mortality rate was highest among White men aged 65 to 79 years (4245.4 deaths per 100 000 person-years). Drug overdose was a leading cause of death across age, gender, and race and ethnicity groups, while suicide uniquely affected young PEH and HIV infection and homicide uniquely affected Black and Hispanic/Latinx PEH.

Conclusions and Relevance

In this large cohort study of PEH, all-cause and cause-specific mortality varied by age, gender, and race and ethnicity. Tailored interventions focusing on those at elevated risk for certain causes of death are essential for reducing mortality disparities across homeless-experienced groups.

Causes of Excess Mortality in Veterans Treated for Posttraumatic Stress Disorder

INTRODUCTION

Published research indicates that posttraumatic stress disorder (PTSD) is associated with increased mortality. However, causes of death among treatment-seeking patients with PTSD remain poorly characterized. The study objective was to describe causes of death among Veterans with PTSD to inform preventive interventions for this treatment population.

METHODS

A retrospective cohort study was conducted for all Veterans who initiated PTSD treatment at any Department of Veterans Affairs Medical Center from fiscal year 2008 to 2013. The primary outcome was mortality within the first year after treatment initiation. In 2018, collected data were analyzed to determine leading causes of death. For the top ten causes, standardized mortality ratios (SMRs) were calculated from age- and sex-matched mortality tables of the U.S. general population.

RESULTS

A total of 491,040 Veterans were identified who initiated PTSD treatment. Mean age was 48.5 (±16.0) years, 90.7% were male, and 63.5% were of white race. In the year following treatment initiation, 1.1% (5,215/491,040) died. All-cause mortality was significantly higher for Veterans with PTSD compared with the U.S. population (SMR=1.05, 95% CI=1.02, 1.08, p<0.001). Veterans with PTSD had a significant increase in mortality from suicide (SMR=2.52, 95% CI=2.24, 2.82, p<0.001), accidental injury (SMR=1.99, 95% CI=1.83, 2.16, p<0.001), and viral hepatitis (SMR=2.26, 95% CI=1.68, 2.93, p<0.001) versus the U.S.

POPULATION

Of those dying from accidental injury, more than half died of poisoning (52.3%, 325/622).

CONCLUSIONS

Veterans with PTSD have an elevated risk of death from suicide, accidental injury, and viral hepatitis. Preventive interventions should target these important causes of death.

VHA-Enrolled Homeless Veterans Are at Increased Risk for Eating Disorder Diagnoses

Introduction

Veterans are overrepresented in the U.S. homeless population, comprising 8.6% of the general U.S. population, but 14% of the homeless population. Homeless veterans have several risk factors for eating disorder diagnoses, but the association of homelessness and eating disorders in this population is understudied. Given limited access to adequate food given their diminished resources, it is critical to better understand risk for eating disorders as a function of homelessness.

Materials and Methods

Administrative data on homelessness, eating disorder diagnoses, and related comorbidities occurring within the first 5 years of Veterans Health Administration (VHA) healthcare utilization between 2004 and 2014 in 265,806 Iraq/Afghanistan veterans were extracted from VHA medical records. Logistic regression analysis estimated the risk for eating disorders as a function of homelessness while accounting for demographic, military, and mental health covariates.

Results

Homelessness was observed in 11,876 veterans (4.5%), and of these, 71 (0.6%) had an eating disorder diagnosis. Odds of having an eating disorder diagnosis were 59% higher (adjusted odds ratio = 1.59, 95% confidence interval [1.21-2.09]) among homeless veterans relative to domiciled veterans.

Conclusions

A diagnosis of eating disorders in veterans is rare at the VHA, however, the current study found that homelessness may increase risk for eating disorders in this population. Unique strategies to provide evidenced-based care while accounting for inadequate daily resources are needed to reduce the risk of eating disorders in this population.

Mortality Among Unsheltered Homeless Adults in Boston, Massachusetts, 2000-2009

IMPORTANCE

Previous studies have shown high mortality rates among homeless people in general, but little is known about the patterns of mortality among "rough sleepers," the subgroup of unsheltered urban homeless people who avoid emergency shelters and primarily sleep outside.

OBJECTIVES

To assess the mortality rates and causes of death for a cohort of unsheltered homeless adults from Boston, Massachusetts.

DESIGN, SETTING, AND PARTICIPANTS

A 10-year prospective cohort study (2000-2009) of 445 unsheltered homeless adults in Boston, Massachusetts, who were seen during daytime street and overnight van clinical visits performed by the Boston Health Care for the Homeless Program's Street Team during 2000. Data used to describe the unsheltered homeless cohort and to document causes of death were gathered from clinical encounters, medical records, the National Death Index, and the Massachusetts Department of Public Health death occurrence files. The study data set was linked to the death occurrence files by using a probabilistic record linkage program to confirm the deaths. Data analysis was performed from May 1, 2015, to September 6, 2016.

EXPOSURE

Being unsheltered in an urban setting.

MAIN OUTCOMES AND MEASURES

Age-standardized all-cause and cause-specific mortality rates and age-stratified incident rate ratios that were calculated for the unsheltered adult cohort using 2 comparison groups: the nonhomeless Massachusetts adult population and an adult homeless cohort from Boston who slept primarily in shelters.

RESULTS

Of 445 unsheltered adults in the study cohort, the mean (SD) age at enrollment was 44 (11.4) years, 299 participants (67.2%) were non-Hispanic white, and 72.4% were men. Among the 134 individuals who died, the mean (SD) age at death was 53 (11.4) years. The all-cause mortality rate for the unsheltered cohort was almost 10 times higher than that of the Massachusetts population (standardized mortality rate, 9.8; 95% CI, 8.2-11.5) and nearly 3 times higher than that of the adult homeless cohort (standardized mortality rate, 2.7; 95% CI, 2.3-3.2). Non-Hispanic black individuals had more than half the rate of death compared with non-Hispanic white individuals, with a rate ratio of 0.4 (95% CI, 0.2-0.7; P < .001). The most common causes of death were noncommunicable diseases (eg, cancer and heart disease), alcohol use disorder, and chronic liver disease.

CONCLUSIONS AND RELEVANCE

Mortality rates for unsheltered homeless adults in this study were higher than those for the Massachusetts adult population and a sheltered adult homeless cohort with equivalent services. This study suggests that this distinct subpopulation of homeless people merits special attention to meet their unique clinical and psychosocial needs.

Mortality and Cause of Death in Younger Homeless Veterans

OBJECTIVES

Increased mortality has been documented in older homeless veterans. This retrospective study examined mortality and cause of death in a cohort of young and middle-aged homeless veterans.

METHODS

We examined US Department of Veterans Affairs records on homelessness and health care for 2000-2003 and identified 23 898 homeless living veterans and 65 198 non-homeless living veterans aged 30-54. We used National Death Index records to determine survival status. We compared survival rates and causes of death for the 2 groups during a 10-year follow-up period.

RESULTS

A greater percentage of homeless veterans (3905/23 898, 16.3%) than non-homeless veterans (4143/65 198, 6.1%) died during the follow-up period, with a hazard ratio for risk of death of 2.9. The mean age at death (52.3 years) for homeless veterans was approximately 1 year younger than that of non-homeless veterans (53.2 years). Most deaths among homeless veterans (3431/3905, 87.9%) and non-homeless veterans (3725/4143, 89.9%) were attributed to 7 cause-of-death categories in the International Classification of Diseases, 10th Revision (cardiovascular system; neoplasm; external cause; digestive system; respiratory system; infectious disease; and endocrine, nutritional, and metabolic diseases). Death by violence was rare but was associated with a significantly higher risk among homeless veterans than among non-homeless veterans (suicide hazard ratio = 2.7; homicide hazard ratio = 7.6).

CONCLUSIONS

Younger and middle-aged homeless veterans had higher mortality rates than those of their non-homeless veteran peers. Our results indicate that homelessness substantially increases mortality risk in veterans throughout the adult age range. Health assessment would be valuable for assessing the mortality risk among homeless veterans regardless of age.

Predictors of Mortality in Older Homeless Veterans

Objectives

In this analysis of a cohort of older homeless veterans, we examined psychosocial, health, housing, and employment characteristics to identify predictors of mortality.

Method

Our sample of 3,620 older veterans entered Veteran Affairs homeless programs in years 2000-2003. Fifteen variables from a structured interview described this sample and served as predictors. National Death Index data for years 2000-2011 were used to ascertain death. Survival table analyses were conducted to estimate and plot cumulative survival functions. To determine predictors and estimate hazard functions, Cox proportional hazards regression analysis was conducted.

Results

Five variables (presence of a serious health issue, hospitalization for alcohol abuse, alcohol dependency, unemployment for 3 years, and age 60+) were associated with increased risk of death; three (non-White, drug dependency, and dental problems) were associated with reduced risk. A risk score, based on total unit-weighted risk for all eight predictors, was used to identify three groups that were found to differ significantly in mortality.

Conclusions

These analyses underline the jeopardy faced by older homeless veterans in terms of early death. We were able to identify several variables associated with mortality; more importantly, we were able to show that a risk score based on status for these variables was significantly related to survival.

Homelessness among a nationally representative sample of US veterans: prevalence, service utilization, and correlates

PURPOSE

To examine the prevalence of lifetime homelessness among veterans and use of Veterans Affairs (VA) homeless services, as well as their association with sociodemographic and clinical characteristics.

METHODS

A nationally representative sample of 1533 US veterans was surveyed July-August 2015.

RESULTS

Among all veterans, 8.5 % reported any lifetime homelessness in their adult life, but only 17.2 % of those reported using VA homeless services. Prevalence of homelessness and VA homeless service use did not significantly differ by gender. Being low income, aged 35-44, and having poor mental and physical health were each independently associated with lifetime homelessness. Veterans who were White or lived in rural areas were significantly less likely to have used VA homeless services.

CONCLUSIONS

Homelessness remains a substantial problem across different generations of veterans. The low reported uptake of VA homeless services suggests there are barriers to care in this population, especially for veterans who live in rural areas. Governmental resources dedicated to veteran homelessness should be supported, and obtaining accurate prevalence estimates are important to tracking progress over time.

Missing the obvious: psychosocial obstacles in Veterans with hepatocellular carcinoma

BACKGROUND

Socioeconomic disparities in patients with hepatocellular carcinoma (HCC) influence medical treatment. In addition to socioeconomic barriers, the Veteran population suffers from significant psychosocial obstacles. This study identifies the social challenges that Veterans face while undergoing treatment for HCC.

METHODS

One hundred Veterans at the Palo Alto VA treated for HCC from 2009 to 2014 (50 consecutive patients who underwent a surgical procedure; 50 treated with intra-arterial therapy) were retrospectively reviewed.

RESULTS

Substance abuse history was identified in 96%, and half were unemployed. Most patients survived on a limited income [median $1340, interquartile range (IQR) 900-2125]; 36% on ≤ $1000/month, 37% between $1001-2000/month and 27% with >$2000/month. A history of homelessness was found in 30%, more common in those of the lowest income (57% of ≤$1K/month group, 23% of $1-2K/month group and 9% of >$2K/month group, P < 0.01). Psychiatric illness was present in 64/100 patients; among these the majority received ongoing psychiatric treatment. Transportation was provided to 23% of patients who would otherwise have been unable to attend medical appointments.

CONCLUSIONS

Psychiatric disease and substance abuse are highly prevalent among Veterans with HCC. Most patients survive on a very meager income. These profound socioeconomic and psychosocial problems must be recognized when providing care for HCC to this population to provide adequate treatment and surveillance.

Tobacco-, alcohol-, and drug-attributable deaths and their contribution to mortality disparities in a cohort of homeless adults in Boston

OBJECTIVES

We quantified tobacco-, alcohol-, and drug-attributable deaths and their contribution to mortality disparities among homeless adults.

METHODS

We ascertained causes of death among 28 033 adults seen at the Boston Health Care for the Homeless Program in 2003 to 2008. We calculated population-attributable fractions to estimate the proportion of deaths attributable to tobacco, alcohol, or drug use. We compared attributable mortality rates with those for Massachusetts adults using rate ratios and differences.

RESULTS

Of 1302 deaths, 236 were tobacco-attributable, 215 were alcohol-attributable, and 286 were drug-attributable. Fifty-two percent of deaths were attributable to any of these substances. In comparison with Massachusetts adults, tobacco-attributable mortality rates were 3 to 5 times higher, alcohol-attributable mortality rates were 6 to 10 times higher, and drug-attributable mortality rates were 8 to 17 times higher. Disparities in substance-attributable deaths accounted for 57% of the all-cause mortality gap between the homeless cohort and Massachusetts adults.

CONCLUSIONS

In this clinic-based cohort of homeless adults, over half of all deaths were substance-attributable, but this did not fully explain the mortality disparity with the general population. Interventions should address both addiction and non-addiction sources of excess mortality.

Homeless and incarcerated: an epidemiological study from Canada

BACKGROUND

Incarceration and homelessness are closely related yet studied rarely. This article aimed to study the incarcerated homeless and identify specific vulnerabilities, which rendered them different from the nonincarcerated homeless. It also aimed to describe the homeless population and its significant involvement with the criminal justice and enforcement system.

METHODS

Data were derived from the British Columbia Health of the Homeless Study (BCHOHS), carried out in three cities in British Columbia, Canada: the large urban center Vancouver (n = 250), Victoria (n = 150) and Prince George (n = 100). Measures included socio-demographic information, the Maudsley Addiction Profile (MAP), the Childhood Trauma Questionnaire (CTQ) and the Mini International Neuropsychiatric Interview (MINI) Plus.

RESULTS

Incarcerated homeless were more often male (66.6%), were in foster care (56.4%) and had greater substance use especially of crack cocaine (69.6%) and crystal methamphetamine (78.7%). They also had greater scores on emotional and sexual abuse domains of CTQ, indicating greater abuse. A higher prevalence of depression (57%) and psychotic disorders (55.3%) was also observed. Risk factors identified which had a positive predictor value were male gender (p < .001; odds ratio (OR) = 2.8; 95% confidence interval (CI): 1.7-4.4), a diagnosis of depression (p = .02; 95% CI: 1.1-4.4) and severe emotional neglect (p = .02; 95% CI: 1.1-3.2) in the childhood.

CONCLUSION

Homeless individuals may be traumatized at an early age, put into foster care, rendered homeless, initiated into substance use and re-traumatized on repeated occasions in adult life, rendering them vulnerable to incarceration and mental illness.

The effects of homelessness on Veterans' health care service use: an evaluation of independence from comorbidities

OBJECTIVES

This study evaluates the prevalence of Multiple Comorbid Chronic Disease (MCCD) within homeless and non-homeless Veterans and the association between MCCD and inpatient medical care.

METHODS

All individuals seen in the VA North Texas Health Care System between October 1, 2009 and September 30, 2010 (n = 102,034) were evaluated. Homelessness during the year and the number of common chronic diseases were evaluated for an association with likelihood of medical and psychiatric hospitalizations, bed days of care, inpatient substance treatment, rehabilitation admissions, and emergency department visits.

RESULTS

Homeless Veterans had higher all-cause mortality rates and rates of use of almost all resources after controlling for chronic disease burden using the Charlson Comorbidity Index, psychiatric illnesses, substance use disorders, and demographic variables.

CONCLUSIONS

Homelessness Veterans are vulnerable to a high use of resources and mortality, independent of medical and psychiatric conditions. This finding should focus additional attention on reducing homelessness.

The effect of local policy actions on mortality among homeless people: a before-after study

BACKGROUND

Homeless people have a 3-5-fold increased risk of mortality compared with general populations. After 2005, policy actions being implemented in Rotterdam, the Netherlands, have improved the living conditions of this group. This study examines the effect of policies aimed at improving living conditions on mortality risks of the homeless.

METHODS

Register-based 10-year follow-up study of homeless in Rotterdam, the Netherlands. The participants are homeless adults (aged 18+ years) who visited one or more services for homeless people in Rotterdam in 2001. The intervention of local policies after 2005 was to get homeless people into housing, increase their participation in employment and other regular daytime activities, and controlling drug and alcohol addictions. The main outcome measure is mortality rate ratios calculated using Poisson regression. Differences in mortality between the periods 2001-05 vs. 2006-10 were assessed.

RESULTS

The cohort of homeless adults in 2001 consisted of 1870 men and 260 women, with a mean age of 40.3 years. During the 10 years of follow-up, 265 persons (232 male and 33 female) died. Adjusted for age and sex, no significant difference in mortality was observed between the periods 2001-05 and 2006-10 (P = 0.9683). A different splitting in periods did not change the results.

CONCLUSION

Five years of local policy efforts improved their living conditions, but left the mortality rate of a homeless cohort unchanged. Incomplete reach of the program and long previous histories of homelessness ask for additional policies beyond the provision of housing and other services. Attention to the prevention of homelessness seems needed.

Characteristics of homeless adults with serious mental illness served by a state mental health transitional shelter

Specialized transitional shelters are available in various cities to provide assistance to homeless individuals with serious mental illness. Little is known about the population using such shelters. The authors conducted a retrospective chart review to collect demographic, social, and clinical data of residents in a state-operated mental health transitional shelter in Massachusetts. A total of 74 subjects were included. Schizophrenia-spectrum disorders were present in 67.6 % of the sample and mood disorders in 35.1 %. Substance use disorders were documented in 44.6 %. Chronic medical illness (mostly hypertension, dyslipidemia, asthma, and diabetes) was found in 82.4 %. The co-occurrence of a psychiatric and substance use disorder and chronic medical illness was found in 36.5 %. The majority (75.7 %) of patients had a history of legal charges. Homeless individuals with serious mental illness served by specialized transitional shelters represent a population with complex psychiatric, medical and social needs.

Mortality and life expectancy in homeless men and women in Rotterdam: 2001-2010

Background

Data on mortality among homeless people are limited. Therefore, this study aimed to describe mortality patterns within a cohort of homeless adults in Rotterdam (the Netherlands) and to assess excess mortality as compared to the general population in that city.

Methods

Based on 10-year follow-up of homeless adults aged ≥ 20 years who visited services for homeless people in Rotterdam in 2001, and on vital statistics, we assessed the association of mortality with age, sex and type of service used (e.g. only day care, convalescence care, other) within the homeless cohort, and also compared mortality between the homeless and general population using Poisson regression. Life tables and decomposition methods were used to examine differences in life expectancy.

Results

During follow-up, of the 2096 adult homeless 265 died. Among the homeless, at age 30 years no significant sex differences were found in overall mortality rates and life expectancy. Compared with the general Rotterdam population, mortality rates were 3.5 times higher in the homeless cohort. Excess mortality was larger in women (rate ratio [RR] RR 5.56, 95% CI 3.95–7.82) as compared to men (RR 3.31, 95% CI 2.91–3.77), and decreased with age (RR 7.67, 95% CI 6.87–8.56 for the age group 20–44 and RR 1.63, 95% CI 1.41–1.88 for the age group 60+ years). Life expectancy at age 30 years was 11.0 (95% CI 9.1–12.9) and 15.9 (95% CI 10.3–21.5) years lower for homeless men and women compared to men and women in the general population respectively.

Conclusion

Homeless adults face excessive losses in life expectancy, with greatest disadvantages among homeless women and the younger age groups.

Alcohol use disorders and mortality: a systematic review and meta-analysis

AIMS

To conduct a systematic review and meta-analysis on all-cause mortality in people with alcohol use disorders.

METHODS

Using the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines, studies were identified through MEDLINE, EMBASE, and Web of Science up to August, 2012. Prospective and historical cohort studies including a comparison of alcohol use disorder with a control group investigating all-cause mortality risk were included.

RESULTS

This meta-analysis included 81 observational studies with 221 683 observed deaths among 853 722 people with alcohol use disorder. In men, the relative risk (RR) among clinical samples was 3.38 (95% confidence interval [CI]: 2.98-3.84); in women it was 4.57 (95% CI: 3.86-5.42). Alcohol use disorders identified in general population surveys showed a twofold higher risk compared with no alcohol use disorder in men; no data were available for women. RRs were markedly higher for those ≤40 years old (ninefold in men, 13-fold in women) while still being at least twofold among those aged 60 years or older.

CONCLUSIONS

Mortality in people with alcohol use disorders is markedly higher than thought previously. Women have generally higher mortality risks than men. Among all people with alcohol use disorders, people in younger age groups and people in treatment show substantially higher mortality risk than others in that group.

Mortality among homeless adults in Boston: shifts in causes of death over a 15-year period

BACKGROUND

Homeless persons experience excess mortality, but US-based studies on this topic are outdated or lack information about causes of death. To our knowledge, no studies have examined shifts in causes of death for this population over time.

METHODS

We assessed all-cause and cause-specific mortality rates in a cohort of 28 033 adults 18 years or older who were seen at Boston Health Care for the Homeless Program from January 1, 2003, through December 31, 2008. Deaths were identified through probabilistic linkage to the Massachusetts death occurrence files. We compared mortality rates in this cohort with rates in the 2003-2008 Massachusetts population and a 1988-1993 cohort of homeless adults in Boston using standardized rate ratios with 95% confidence intervals.

RESULTS

A total of 1302 deaths occurred during 90 450 person-years of observation. Drug overdose (n = 219), cancer (n = 206), and heart disease (n = 203) were the major causes of death. Drug overdose accounted for one-third of deaths among adults younger than 45 years. Opioids were implicated in 81% of overdose deaths. Mortality rates were higher among whites than nonwhites. Compared with Massachusetts adults, mortality disparities were most pronounced among younger individuals, with rates about 9-fold higher in 25- to 44-year-olds and 4.5-fold higher in 45- to 64-year-olds. In comparison with 1988-1993 rates, reductions in deaths from human immunodeficiency virus (HIV) were offset by 3- and 2-fold increases in deaths owing to drug overdose and psychoactive substance use disorders, resulting in no significant difference in overall mortality.

CONCLUSIONS

The all-cause mortality rate among homeless adults in Boston remains high and unchanged since 1988 to 1993 despite a major interim expansion in clinical services. Drug overdose has replaced HIV as the emerging epidemic. Interventions to reduce mortality in this population should include behavioral health integration into primary medical care, public health initiatives to prevent and reverse drug overdose, and social policy measures to end homelessness.

Community psychiatry: what should future psychiatrists learn?

Community psychiatry training is required by all adult psychiatry residency training programs. Unlike other core elements of training, the specific content is not clearly articulated, leaving program design and content up to individual programs. At the same time, the meaning of "community psychiatry" is increasingly in the eye of the beholder; traditional structures and systems have lost funding, services are more diffuse, and the traditional medical model is becoming less valued. In this column we describe an approach to training in community psychiatry that is intended to prepare future psychiatrists for the clinical and systems challenges they will undoubtedly face and that achieves this goal through trainees' caring for an especially vulnerable subpopulation--homeless individuals with severe and persistent mental illness. We describe how this model teaches residents to think simultaneously at both the individual and the systems levels and enables them to understand the critical need to use nontraditional treatment approaches in order to provide comprehensive care for this marginalized population. We believe that this clinical and training paradigm can be replicated and might guide other residency training programs in their approach to teaching community psychiatry.

Health status, quality of life, residential stability, substance use, and health care utilization among adults applying to a supportive housing program

Supportive housing, defined as subsidized housing in conjunction with site-based social services, may help improve the health and residential stability of highly disadvantaged individuals. This study examined changes in health status, quality of life, substance use, health care utilization, and residential stability among 112 homeless and vulnerably housed individuals who applied to a supportive housing program in Toronto, Canada, from December 2005 to June 2007. Follow-up interviews were conducted every 6 months for 18 months. Comparisons were made between individuals who were accepted into the program (intervention) and those who were wait-listed (usual care) using repeated-measures analyses. Individuals who were accepted into the housing program experienced significantly greater improvements in satisfaction with living situation compared with individuals in the usual care group (time, F(3,3,261) = 47.68, p < 0.01; group × time, F(3,3,261) = 14.60, p < 0.01). There were no significant differences in other quality of life measures, health status, health care utilization, or substance use between the two groups over time. Significant improvement in residential stability occurred over time, independent of assigned housing group (time, F(3,3,261) = 9.96, p < 0.01; group × time, F(3,3,261) = 1.74, p = 0.17). The ability to examine the effects of supportive housing on homeless individuals was limited by the small number of participants who were literally homeless at baseline and by the large number of participants who gained stable housing during the study period regardless of their assigned housing status. Nonetheless, this study shows that highly disadvantaged individuals with a high prevalence of poor physical and mental health and substance use can achieve stable housing.

The impact of shelter use and housing placement on mortality hazard for unaccompanied adults and adults in family households entering New York City shelters: 1990-2002

This study examines mortality among New York City (NYC) homeless shelter users, assessing the relationships between mortality hazard and time in shelter, patterns of homelessness, and subsequent housing exits for both adults in families and single adults. Administrative records from the NYC shelter system were matched with death records from the Social Security Administration for 160,525 persons. Crude mortality rates and life tables were calculated, and survival analyses were undertaken using these data. Life expectancy was 64.2 and 68.6 years for single adult males and single adult females, respectively, and among adults in families, life expectancy was 67.2 and 70.1 years for males and females, respectively. For both groups, exits to stable housing (subsidized or non-subsidized) were associated with reduced mortality hazard. And while mortality hazard was substantially reduced for the time adults were in shelters, extended shelter use patterns were associated with increased mortality hazard. Differences between single homelessness and family homelessness extend to disparities in mortality rates. Although causal links cannot be established here, results suggest that, for both subgroups of the homeless population, prompt resolution of homelessness and availability of housing interventions may contribute to reduced mortality.

Psychiatric disorders and mortality among people in homeless shelters in Denmark: a nationwide register-based cohort study

BACKGROUND

The increased mortality of homeless people compared with non-homeless people might be linked to psychiatric disorders. However, homeless people are, because of their insufficient accommodation, difficult to sample and monitor, which has limited previous studies. We aimed to assess registered psychiatric disorders, mortality, and predictors of mortality in the homeless shelter population in Denmark.

METHODS

We did a nationwide, prospective, register-based cohort study of homeless people aged 16 years and older who were registered in the Danish Homeless Register between Jan 1, 1999, and Dec 31, 2009. We calculated the proportion of registered psychiatric disorders, overall and cause-specific standardised mortality ratio (SMR), and life expectancy. Hazard ratios (HRs) were used to assess predictors of death.

FINDINGS

32,711 homeless people (23,040 men and 9671 women) were included in the study population. 14,381 men (62·4%) and 5632 women (58·2%) had registered psychiatric disorders, and 11,286 men (49·0%) and 3564 women (36·9%) had a substance abuse diagnosis. During the study period, 3839 men (16·7%) and 951 women (9·8%) died. The overall SMR for men was 5·6 (95% CI 5·4-5·8) and for women was 6·7 (6·2-7·1), and external causes accounted for 1161 (27·9%) of 4161 deaths for which information on the cause was available. Remaining life expectancy at age 15-24 years was 21·6 years (95% CI 21·2-22·1) and 17·4 years (16·4-18·5) lower for homeless men and women, respectively, than the general population. Registered substance abuse disorder was associated with the highest mortality risk compared with no psychiatric contact registered (adjusted HR 1·4, 95% CI 1·3-1·5 for men; 1·7, 1·4-2·1 for women).

INTERPRETATION

Health problems are extensive in the homeless shelter population and there is an urgent need for more sustained efforts to reduce the high morbidity and mortality, especially from external causes. Register data is an important resource to supplement existing knowledge on homeless people with more valid and detailed information.

Mortality and causes of death among homeless women and men in Stockholm

AIM

To study the mortality and causes of death among homeless men and women in relation to the risk indicators, previous treatment for alcohol and drug abuse, previous treatment for mental disorders and non-Swedish citizenship.

METHODS

The mortality was studied in a cohort comprising 1,757 men and 526 women compared with the general population and persons with inpatient treatment for alcohol- and drug-related disorders. The follow-up period was from 1995 to 1997 until the end of 2005. The causes of death were analyzed.

RESULTS

421 deaths occurred during the follow-up period. The relative risk of death was 3.1, with no difference in mortality between homeless men and homeless women. Previous treatment for alcohol and drug abuse disorders was related to excess mortality and previous treatment for mental disease to lower mortality. Homeless people with inpatient treatment for alcohol or drug use disorders had no higher mortality than the general population in Stockholm with a similar history. There was a dominance of alcohol- and drug-related causes of death.

DISCUSSION

Compared with previous studies of homeless people in Stockholm the excess mortality among men found in this study is of the same magnitude. Mortality among women is lower. The mortality rate in homeless people with previous treatment for an alcohol and illicit drug use disorder did not differ from those treated for these disorders in the general population.

CONCLUSIONS

The most important finding is that excess mortality among homeless men and women in Stockholm is entirely related to alcohol and drug abuse.

The epidemiology of excess mortality in people with mental illness

OBJECTIVE

to investigate the burden of excess mortality among people with mental illness in developed countries, how it is distributed, and whether it has changed over time.

METHOD

we conducted a systematic search of MEDLINE, restricting our attention to peer-reviewed studies and reviews published in English relating to mortality and mental illness. Because of the large number of studies that have been undertaken during the last 30 years, we have selected a representative cross-section of studies for inclusion in our review.

RESULTS

there is substantial excess mortality in people with mental illness for almost all psychiatric disorders and all main causes of death. Consistently elevated rates have been observed across settings and over time. The highest numbers of excess deaths are due to cardiovascular and respiratory diseases. With life expectancy increasing in the general population, the disparity in mortality outcomes for people with mental illness is increasing.

CONCLUSIONS

without the development of alternative approaches to promoting and treating the physical health of people with mental illness, it is possible that the disparity in mortality outcomes will persist.

Mortality among residents of shelters, rooming houses, and hotels in Canada: 11 year follow-up study

OBJECTIVE

To examine mortality in a representative nationwide sample of homeless and marginally housed people living in shelters, rooming houses, and hotels.

DESIGN

Follow-up study.

SETTING

Canada 1991-2001.

PARTICIPANTS

15 100 homeless and marginally housed people enumerated in 1991 census.

MAIN OUTCOME MEASURES

Age specific and age standardised mortality rates, remaining life expectancies at age 25, and probabilities of survival from age 25 to 75. Data were compared with data from the poorest and richest income fifths as well as with data for the entire cohort

RESULTS

Of the homeless and marginally housed people, 3280 died. Mortality rates among these people were substantially higher than rates in the poorest income fifth, with the highest rate ratios seen at younger ages. Among those who were homeless or marginally housed, the probability of survival to age 75 was 32% (95% confidence interval 30% to 34%) in men and 60% (56% to 63%) in women. Remaining life expectancy at age 25 was 42 years (42 to 43) and 52 years (50 to 53), respectively. Compared with the entire cohort, mortality rate ratios for men and women, respectively, were 11.5 (8.8 to 15.0) and 9.2 (5.5 to 15.2) for drug related deaths, 6.4 (5.3 to 7.7) and 8.2 (5.0 to 13.4) for alcohol related deaths, 4.8 (3.9 to 5.9) and 3.8 (2.7 to 5.4) for mental disorders, and 2.3 (1.8 to 3.1) and 5.6 (3.2 to 9.6) for suicide. For both sexes, the largest differences in mortality rates were for smoking related diseases, ischaemic heart disease, and respiratory diseases.

CONCLUSIONS

Living in shelters, rooming houses, and hotels is associated with much higher mortality than expected on the basis of low income alone. Reducing the excessively high rates of premature mortality in this population would require interventions to address deaths related to smoking, alcohol, and drugs, and mental disorders and suicide, among other causes.

Predicting mortality in veterans with posttraumatic stress disorder thirty years after Vietnam

Previous research has demonstrated elevated mortality rates among Vietnam-era veterans with posttraumatic stress disorder, especially deaths resulting from nonmedical causes. However, information on the relative contribution of particular risk factors to increased mortality is limited. We used receiver operating characteristics methodology to identify patient-level characteristics that predicted 7-year mortality in 79,551 middle-aged, male, posttraumatic stress disorder-diagnosed outpatients seeking mental health treatment within the Veterans Affairs Health Care System between April 1, 1998 and September 30, 1998. Receiver operating characteristics models indicated that the strongest predictor of mortality was a recent history of medical hospitalization, followed by severity of medical diagnoses and presence of a substance disorder. Results highlight the importance of addressing comorbid medical illnesses and addictive disorders when caring for this population.

Depression, posttraumatic stress disorder, and mortality

OBJECTIVE

To determine whether a history of depression and/or posttraumatic stress disorder (PTSD) is associated with all-cause mortality in primary care patients over an average of 2 years.

METHODS

Patients from seven Department of Veterans Affairs medical centers completed mailed questionnaires. Depression and PTSD status were determined from patient self-report of a prior diagnosis and/or electronic administrative data. Date of death was ascertained from Veterans Health Information Systems and Technology Architecture and the Department of Veterans Affairs' Beneficiary Identification and Records Locator System.

RESULTS

Among 35,715 primary care patients, those with a history of depression without a history of PTSD (n = 6876) were at increased risk of death over an average of 2 years compared with patients with neither depression nor PTSD after adjustment for demographic variables, health behaviors, and medical comorbidity (hazard ratio (HR) = 1.17; 95% Confidence Interval (CI) = 1.06-1.28). However, patients with a history of PTSD without a history of depression (n = 748) were not at increased risk of death compared with patients with neither depression nor PTSD (HR = 0.84; 95% CI = 0.63-1.13). Patients with a history of both (n = 3762) were at increased risk of death after adjustment for demographic factors, although not after additional adjustment for health behaviors and medical comorbidity (HR = 0.90; 95% CI = 0.78-1.04).

CONCLUSIONS

In a large sample of veterans, a prior diagnosis of depression, but not PTSD, was associated with an increased risk of death over an average of 2 years after adjusting for age, demographic variables, health behaviors, and medical comorbidity.

Factors associated with mortality in a cohort of Australian prisoners

We examined factors associated with increased mortality in a cohort of 85,203 adults with a history of imprisonment in New South Wales, Australia, between 1988 and 2002. Information on death was collected through linkage to the Australian National Death Index. The influence of demographic and criminological factors on the standardised mortality ratio (SMR) for all-cause mortality, and deaths due to drug overdose and suicide was examined using negative binomial regression models. The number of deaths identified was 5,137 (4,714 men, 423 women, 303 in custody). The overall SMR was 3.7 (3.6-3.8) in men and 7.8 (7.1-8.5) in women. SMRs raised for deaths due to drug overdose (men: 12.8, women: 50.3) and suicide (men: 4.8, women: 12.2). The high SMR was associated with hospitalisation for mental illness, multiple imprisonments, and early stage of follow-up independently of causes of death. Being released from prison increased the SMRs for all-cause and drug-related mortality, but not suicide. For women, significant trends for decreasing risk with increasing age were noted. Minority groups, in particular men, had a lower risk of death than white people. In men a sex or drug offence was associated with a lower risk and a property or violence offence was related to higher mortality. Our results reinforce how disadvantaged prisoners are, measured by mortality as the most fundamental scale of human wellbeing. Certain demographic and imprisonment characteristics are indicators of high mortality among this population. The underlying causes of some of these characteristics such as mental illness or multiple imprisonments are potentially treatable and preventable. Prison health services need to develop interventions targeting high-risk groups to avoid this situation.

Mortality, mental disorders and addiction: a 5-year follow-up of 82 homeless men in Stockholm

A 5-year follow-up study was performed on 82 homeless men, with mental problems, who had been contacted by an outreach team run by the Social welfare administration of Stockholm 1995/1996. Data have been collected from the Cause of Death Register, death certificates, forensic autopsy reports, hospital medical reports, Hospital Discharge Register, interviews with social workers and with those men who were able to participate. The standardized mortality ratio (SMR) was 4.7 times higher than expected. The highest mortality was found in the group where drug addiction was dominant; 46% had died. In the group of men with severe psychiatric disorders, with diagnosis such as schizophrenia, none had died. Compared with the others, they had spent less time in homelessness. Among the survivors, 75% were still homeless at the follow-up in spite of considerable treatment interventions from the social services and health authorities. Residential institutions or treatment seemed to have some protective effect concerning misuse, diseases and injuries. Among the still homeless, the mental health problems combined with substance use problems had increased with 17%. The life and housing situation for the whole group seemed not to have improved, even if fewer of them were staying in hostels for homeless people.

Depression and Other Mental Health Diagnoses After Stroke Increase Inpatient and Outpatient Medical Utilization Three Years Poststroke

OBJECTIVE

Poststroke depression (PSD) has been linked to negative outcomes, including mortality and decreased functioning. However, the effect of PSD and other mental health conditions on inpatient and outpatient healthcare utilization after stroke has not been examined. The primary objective of this study was to evaluate the relationship between PSD and healthcare utilization after stroke. The secondary objective was to evaluate the relationship between other mental health diagnoses and medical utilization after stroke.

METHOD

We examined 3 years of poststroke healthcare utilization data in a national cohort of veterans with ischemic stroke. Mental health diagnoses were identified with inpatient International Classification of Diseases, 9th Revision codes. Multivariate analysis of variance was used to compare patient characteristics and multivariate linear regression to model utilization in: 1) patients with PSD, 2) patients diagnosed with other mental health conditions poststroke, and 3) patients with no mental health diagnosis.

RESULTS

Of 51,119 veterans identified, 2405 (5%) received a PSD diagnosis and 2257 (4%) received a diagnosis of another mental health condition after their stroke. Patients with PSD had significantly more inpatient hospitalization days and outpatient visits than those without any mental health diagnosis, even after adjusting for the number of mental health clinic visits. Likewise, patients diagnosed with other mental health diagnoses had greater medical utilization than patients without any mental health diagnosis. Both PSD and other mental health diagnoses independently predicted medical utilization.

CONCLUSION

Mental health diagnosis after stroke increases inpatient and outpatient healthcare utilization in the first 3 years poststroke. Additional biologic and psychosocial factors should be investigated.

Unmet need for medical care among homeless adults with serious mental illness

OBJECTIVE

The objective of this study was to determine the rates and predictors of unmet medical needs among homeless adults with serious mental illness entering a community-based case management program and those of receipt of medical care in the subsequent 3-month period.

METHODS

We analyzed baseline and follow-up data for 7213 homeless clients in the multisite Access to Community Care and Effective Services and Supports program.

RESULTS

Overall, 43.6% of the sample reported having an unmet need for medical care at baseline; of these subjects, only 36.1% received medical services during the 3 months following program entry. Using multivariate logistic regression modeling, we found that, at baseline, independent correlates of an unmet medical need included lower educational level, increased depressive and psychotic symptoms and greater number of potentially competing needs. None of these variables, however, adversely affected the likelihood of receiving medical care during follow-up. Factors associated with receiving medical services in the 3 months following program entry included receiving outpatient psychiatric services and reporting stronger therapeutic alliance with one's case manager.

CONCLUSIONS

Collaborative case management may play an important role in meeting mentally ill homeless persons' medical needs. Greater efforts are needed to identify and link at-risk clients with appropriate medical services.

Predictors of 5-year mortality following inpatient/residential group treatment for substance use disorders

This study examined the prevalence and predictors of 5-year mortality following treatment for substance use disorders. The predictors were assessed at baseline, at discharge, and at a 1-year follow-up for 3698 male veterans, and included demographic, substance use, medical, and psychological functioning, social support, and continuing care. The annual mortality rate was 2.38%, with an observed/expected ratio of 3.05. After accounting for significant demographic, substance use, psychological, and medical conditions, not having a spouse or partner at intake independently predicted 5-year mortality. After accounting for intake variables, more depression at discharge and more medical conditions, a diagnosis of HIV or AIDS, more ounces of ethanol on a maximum drinking day, and lack of a spouse or partner at the 1-year follow-up independently predicted 5-year mortality. Unexpectedly, good quality relationships were related to a higher mortality risk. Results can be used to increase at-risk patients' motivation for recovery.

Can Shelter-Based Interventions Improve Treatment Engagement in Homeless Individuals With Psychiatric and/or Substance Misuse Disorders?

BACKGROUND

High proportions of homeless individuals have mental illness and substance use disorders. Few of these individuals engage in consistent treatment, although they are likely to benefit from it. Shelter-based interventions to help this population engage in treatment have not been studied in a rigorous manner.

OBJECTIVES

We sought to evaluate the effectiveness of a shelter-based intervention, including intensive outreach by a psychiatric social worker and availability of weekly psychiatrist visits with continuity of care to engage homeless individuals with psychiatric and substance use problems.

RESEARCH DESIGN

This was a randomized controlled trial.

SUBJECTS

A total of 102 individuals were referred to a shelter-based psychiatric clinic.

MEASURES

The primary outcome measure was first appointment attendance at a community mental health center (CMHC). Secondary outcome measures were attendance at second and third CMHC appointments, participation in a substance abuse program, and employment and housing status at shelter exit.

RESULTS

Individuals receiving the intervention were more likely to attend > or =1 CMHC appointment (64.7% versus 37.3%, P = 0.006) and to participate in a substance abuse program (51.4% versus 12.5%, P = 0.0006) than those in the control group. There was a trend towards being more likely to attend 2 CMHC visits (33.3% versus 17.7%, P = 0.083), but no significant differences in attending 3 visits, being employed, or having housing.

CONCLUSIONS

Shelter-based interventions hold promise for improving treatment engagement in homeless populations with psychiatric and substance use problems. Further study should address how to foster care beyond an initial CMHC appointment and clarify key program components using a wider range of outcome measures.

Three year course and outcome of mental illness in homeless men: a prospective longitudinal study based on a representative sample

OBJECTIVE

To report on the 3-year course and outcome of mental illness and social aspects in a representative sample of 265 homeless men living on the street or using overnight shelter.

METHOD

Expert interviews at baseline and at follow-up included the SCID-I and covered cognitive impairment, somatic complaints, use of medical services and psychosocial areas. Of 247 homeless men still alive, at 3-year follow-up, 185 (74.9 %) were successfully traced and interviewed face to face.

RESULTS

There was considerable improvement regarding the housing situation after 3 years. Rates of mental illness decreased from 79 % to 66% over 3 years possibly due to an improved housing situation and increased medical/psychiatric attention and service. The prevalence of mood disorders, substance use disorders and anxiety disorders was significantly lower at 3-year follow-up while psychotic disorders showed a slight increase over time. Thus, in general, more remission than incidence was observed in the 3-year follow-up period. A high rate of use of general medical inpatient services was found. Considering the very high prevalence of mental illness, the use of psychiatric services was very low with some increase over time. Mental health status at 1st assessment did not predict the housing situation at 3 year follow-up. Having had a substance use disorder diagnosis at 1st assessment was a powerful predictor of an unfavorable mental health status at 3 year follow-up. Standardized mortality ratio over 3 years was 4.4.

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.

Causes of death among male veterans who received residential treatment for PTSD

Previous studies have shown elevated mortality among psychiatric and substance abusing patients, including veterans with PTSD. Although early studies showed elevated deaths from external causes among Vietnam veterans in the early postwar years, more recent studies have also shown increased health problems among veterans with PTSD. This study compared mortality due to behavioral causes versus other diseases among 1,866 male veterans treated for PTSD. Death certificates obtained for 110 veterans indicated behavioral causes accounted for 62.4% of deaths, standardized mortality ratio = 3.4-5.5, including accidents (29.4%), chronic substance abuse (14.7%), and intentional death by suicide, homicide, or police (13.8%). Results suggest possible opportunities to improve outcomes of this at-risk patient population through harm reduction interventions and improved continuity of care.

Course of alcoholism in homeless men in Munich, Germany: results from a prospective longitudinal study based on a representative sample

In an earlier paper (Fichter, M. M., Quadflieg, N. (1999). Alcoholism in homeless men in the mid-nineties: results from the Bavarian Public Health Study on Homelessness. European Archives of Psychiatry and Clinical Neuroscience 249:34-44), we reported data on alcoholism and comorbidity in 265 homeless men in Munich. There-as in this paper-we divided the sample into three groups based on a lifetime diagnosis of alcohol dependence (N = 187), alcohol abuse (N = 17), and no diagnosis of alcoholism (N = 61) at baseline assessment. This study reports a three-year prospective longitudinal assessment of the original representative sample of homeless men in Munich. Interviews at baseline and at follow-up included the SCID-I and covered several other areas (cognitive impairment, somatic complaints, use of medical services, and other psychosocial variables). Of 247 homeless men still alive, at three-year follow-up, 185 (74.9%) were successfully traced and personally interviewed. Alcohol dependency in homeless men at first wave assessment (as compared to men not manifesting alcohol abuse or dependence) was associated with a higher proportion of homelessness at three-year follow-up, an increase of alcohol consumption at three-year follow-up, reduction of monthly income, higher death rate, and high use of general medical services but very low utilization of (specific substance) user treatment services. Alcoholism in homeless men constitutes a posited risk factor for an unfavorable course over time with regard to such a person's living situation and health status in spite of more utilization of medical services.

Determinants of receipt of ambulatory medical care in a national sample of mentally ill homeless veterans

BACKGROUND AND OBJECTIVES

This study used the Behavioral Model for Vulnerable Populations to identify determinants of receipt of outpatient medical care within 6 months of initial contact with a national homeless veterans outreach program.

RESEARCH DESIGN

Prospective study.

SUBJECTS

Homeless veterans contacted through the program in 1999 (n = 26,926).

MEASURES

Data from structured interviews conducted at the time of program intake were merged with Veterans Affairs administrative data to determine subsequent medical service use. Logistic regression modeling was used to identify predisposing, enabling, and need factors from traditional and vulnerable domains predictive of receiving medical care.

RESULTS

Overall, 41.8% of subjects received at least one medical visit in the 6 months after program intake; of these, 48.7% had three or more visits. In multivariate analyses, the likelihood of receiving medical care was, among other things, positively associated with age, female gender, and placement in residential treatment and negatively associated with duration of homelessness and being contacted through outreach versus referred or self-referred into the homeless program. Mental illness did not appear to be an additional barrier to initiating medical care; however, a diagnosis of substance abuse or schizophrenia was associated with a decreased likelihood of receiving three or more visits.

CONCLUSION

A majority of homeless veterans contacted through a national outreach program failed to receive medical services within 6 months of program entry. Vulnerable-domain factors were important supplements to traditional variables in predicting use of medical services in the homeless population. Greater efforts are needed to ensure that mentally ill homeless persons are successfully linked with and engaged in medical treatment.
