Psychiatric emergency service use and homelessness, mental disorder, and violence

A Longitudinal Study of Correlates, Discharge Disposition, and Rate of Re-presentation to Emergency Services of Adults who Engage in Non-suicidal Self-injury

OBJECTIVE

In DSM-5, non-suicidal self-injury (NSSI) and suicide attempts (SA) are classified as distinct disorders in the section of conditions for further study. However, some have questioned the validity of distinguishing NSSI from SA. The objective of this study was to longitudinally examine the correlates, discharge disposition, and rate of re-presentation to emergency services of adults who engaged in NSSI and compare them to (a) adults who engage in SA and (b) adults with no self-harm or suicidal ideation (SI).

METHOD

Data came from 4,772 presentations to adult psychiatric services in the emergency departments of tertiary care hospitals in Winnipeg, Canada between January 2009 and June 2012. Chart reviews were conducted for all presentations with NSSI (n = 158), and a sample of those with SA (n = 172) and no SH or SI (n = 173).

RESULTS

Among the adults who returned to emergency services, those who originally presented with SA re-presented significantly sooner than those who presented with NSSI. (χ²(1) = 7.457, p = 0.006). Those who originally presented with NSSI that returned to hospital did not return with repeat NSSI, but instead the majority re-presented with suicidal thoughts and SA. Further, those who re-presented with NSSI and SA were less likely to be hospitalized or to receive a referral to mental health services, and more likely to be discharged to usual care at time of initial presentation.

CONCLUSIONS

Overall, these findings indicate a trajectory of escalation of self-harm behavior for certain people who engage in NSSI, especially those who re-present to emergency services.HIGHLIGHTSA quarter of people with self-harm re-present to emergency services within four-and-a-half years.Those with suicide attempts re-presented significantly sooner than non-suicidal self-injury.There is a need for increased interventions in emergency services for those with self-harm.

Engaging unhoused community members in the design of an alternative first responder program aimed at reducing the criminalization of homelessness

Police are often called to address concerns about people experiencing homelessness, with arrests often resulting from low-level, nonviolent crimes, and violations of minor nuisance ordinances. In Portland, Oregon, advocates lobbied for a new model of emergency response for 911 calls involving unhoused community members and people experiencing behavioral health crises. To ensure the program reflected the needs and perspectives of people experiencing homelessness, teams of researchers, community volunteers, and people with lived experience interviewed 184 people in camps, shelters, and parks. Teams asked unhoused people how the program should be designed, including who the first responders should be, how they should approach individuals in crisis, what resources they should provide, and how they should be trained. This article describes the methods, findings, and recommendations from our collaborative survey process aimed at ensuring that the voices of people experiencing homelessness informed the development of the Portland Street Response pilot program.

Frequency, Prevalence, Interaction, and Gender Differences of Six Psychosocial Factors in Patients Presenting to a Psychiatric Emergency Service

INTRODUCTION

The psychiatric emergency service (PES) has become an increasingly utilized patient care approach over the past 50 years. Psychosocial factors play an important role in PES utilization and disposition of patients in this environment. PES utilization in our region has increased 450% in the past 18 years, while the population has changed <1%. Our objective was to determine the frequency and relationship between six psychosocial factors in our patients, in comparison to the general population.

METHODS

We completed a retrospective chart review of 160 patients selected at random who utilized the PES during 2009-2010. We looked for historical presence of a broken family, abuse or neglect, substance abuse, legal problems, violence, or incomplete education. We also looked at the relationship of these factors to race and gender.

RESULTS

75% had three or more of the factors measured. In our population, substance abuse and broken family were most prevalent. Females had significantly more abuse or neglect as compared to males, while male subjects had significantly more substance abuse and legal issues than females. The presence of a broken family was strongly associated with abuse or neglect, while violence was associated with incomplete education and legal issues. The prevalence of these factors in our patients was higher than the general population.

CONCLUSION

The average patient presenting to the PES has multiple major psychosocial problems at higher frequencies than the general population. Understanding the relationship between multiple psychosocial factors and increasing PES utilization can direct us towards addressing the problems causing the increase in PES presentation. A planned future prospective study will examine the incidence of these psychosocial factors in patients presenting to the PES as compared to the general population.

Effectiveness of a housing support team intervention with a recovery-oriented approach on hospital and emergency department use by homeless people with severe mental illness: a randomised controlled trial

AIMS

Many people who are homeless with severe mental illnesses are high users of healthcare services and social services, without reducing widen health inequalities in this vulnerable population. This study aimed to determine whether independent housing with mental health support teams with a recovery-oriented approach (Housing First (HF) program) for people who are homeless with severe mental disorders improves hospital and emergency department use.

METHODS

We did a randomised controlled trial in four French cities: Lille, Marseille, Paris and Toulouse. Participants were eligible if they were 18 years or older, being absolutely homeless or precariously housed, with a diagnosis of schizophrenia (SCZ) or bipolar disorder (BD) and were required to have a high level of needs (moderate-to-severe disability and past hospitalisations over the last 5 years or comorbid alcohol or substance use disorder). Participants were randomly assigned (1:1) to immediate access to independent housing and support from the Assertive Community Treatment team (social worker, nurse, doctor, psychiatrist and peer worker) (HF group) or treatment as usual (TAU group) namely pre-existing dedicated homeless-targeted programs and services. Participants and interviewers were unmasked to assignment. The primary outcomes were the number of emergency department (ED) visits, hospitalisation admissions and inpatient days at 24 months. Secondary outcomes were recovery (Recovery Assessment Scale), quality of life (SQOL and SF36), mental health symptoms, addiction issues, stably housed days and cost savings from a societal perspective. Intention-to-treat analysis was performed.

RESULTS

Eligible patients were randomly assigned to the HF group (n = 353) or TAU group (n = 350). No differences were found in the number of hospital admissions (relative risk (95% CI), 0.96 (0.76-1.21)) or ED visits (0.89 (0.66-1.21)). Significantly less inpatient days were found for HF v. TAU (0.62 (0.48-0.80)). The HF group exhibited higher housing stability (difference in slope, 116 (103-128)) and higher scores for sub-dimensions of S-QOL scale (psychological well-being and autonomy). No differences were found for physical composite score SF36, mental health symptoms and rates of alcohol or substance dependence. Mean difference in costs was €-217 per patient over 24 months in favour of the HF group. HF was associated with cost savings in healthcare costs (RR 0.62(0.48-0.78)) and residential costs (0.07 (0.05-0.11)).

CONCLUSION

An immediate access to independent housing and support from a mental health team resulted in decreased inpatient days, higher housing stability and cost savings in homeless persons with SCZ or BP disorders.

Service usage by a New Zealand Housing First cohort prior to being housed

Background

The Ending Homelessness in New Zealand: Housing First research programme is evaluating outcomes for people housed in a Housing First programme run by The People's Project in Hamilton, New Zealand. This baseline results paper uses administrative data to look at the scope and duration of their interactions with government services.

Methods

We linked our de-identified cohort to the Integrated Data Infrastructure (IDI). This database contains administrative data on most services provided by the New Zealand Government to citizens. Linkage rates in all datasets were above 90%. This paper reports on the use of government services by the cohort before being housed. We focus on the domains of health, justice and income support.

Results

The cohort of 390 people had over 200,000 recorded interactions across a range of services in their lifetime. The most common services were health, justice and welfare. The homeless cohort had used the services at rates far in excess of the general population. Unfortunately these did not prevent them from becoming homeless.

Conclusion

These preliminary findings show the homeless population have important service delivery needs and a very high level of interaction with government services. This highlights the importance of analysing the contributing factors towards homelessness; for evaluation of interventions such as Housing First, and for understanding the need for integrated systems of government policy and practice to prevent homelessness. This paper also provides the baseline for post-Housing First evaluations.

•

A homeless cohort in New Zealand had a high rate of service usage leading up to engagement with Housing First services.

•

The cohort appeared in government linked data at higher rates than the general population.

•

The cohort had over 200,000 interactions with government services within the five years prior to being housed by Housing First services.

•

This paper shows the need for a systems-wide strategy to prevent homelessness.

Explaining socioeconomic inequalities in illicit drug use disorders in Iran

Background: Drug use disorders are one of the major health problems in societies, which cause physical, psychological, and social damages to individuals. Socioeconomic status is often inversely associated with drug use disorders. The present study aimed at determining the effect of socioeconomic inequality on the prevalence of drug use disorders and identifying its determinants in Iran.

Methods: Data of 7886 individuals aged 15 to 64 years were collected from Iran Mental Health Survey (IranMHS). Initially, the socioeconomic status of the participants was determined by principal component analysis. Later, socioeconomic inequality was measured using the concentration index, and the factors influencing the gap between the high and low socioeconomic groups were identified using the Oaxaca-Blinder Decomposition.

Results: The concentration index for drug use disorders in Iran was -0.29 (standard error= 0.06). The results of decomposition technique revealed that 1.14% and 2.7% of the participants with high and low socioeconomic status were affected by drug use disorders, respectively. In addition, the gap between these 2 groups was found to be 1.65%. Among the studied variables, occupation, marital status, and gender accounted for the highest contribution to inequality, respectively.

Conclusion: There is inequality in the prevalence of drug use disorders in Iran; these disorders are more common in lower socioeconomic group. Based on the findings, it is suggested that improvement in the socioeconomic status of the households, especially for males, the divorced or widowed individuals, and the unemployed may lead to a reduction in inequality in drug use disorders.

The effects of housing stability on service use among homeless adults with mental illness in a randomized controlled trial of housing first

BACKGROUND

Housing First is an effective intervention to stably house and alter service use patterns in a large proportion of homeless people with mental illness. However, it is unknown whether there are differences in the patterns of service use over time among those who do or do not become stably housed and what effect, if any, Housing First has on these differing service use patterns. This study explored changes in the service use of people with mental illness who received Housing First compared to standard care, and how patterns of use differed among people who did and did not become stably housed.

METHODS

The study design was a multi-site randomized controlled trial of Housing First, a supported housing intervention. 2039 participants (Housing First: n = 1131; standard care: n = 908) were included in this study. Outcome variables include nine types of self-reported service use over 24 months. Linear mixed models examined what effects the intervention and housing stability had on service use.

RESULTS

Participants who achieved housing stability, across the two groups, had decreased use of inpatient psychiatric hospitals and increased use of food banks. Within the Housing First group, unstably housed participants spent more time in prison over the study period. The Housing First and standard care groups both had decreased use of emergency departments and homeless shelters.

CONCLUSIONS

The temporal service use changes that occurred as homeless people with mental illness became stably housed are similar for those receiving Housing First or standard care, with the exception of time in prison. Service use patterns, particularly with regard to psychiatric hospitalizations and time in prison, may signify persons who are at-risk of recurrent homelessness. Housing support teams should be alert to the impacts of stay-based services, such as hospitalizations and incarcerations, on housing stability and offer an increased level of support to tenants during critical periods, such as discharges.

Improving risk management for violence in mental health services: a multimethods approach

Background

Mental health professionals increasingly carry out risk assessments to prevent future violence by their patients. However, there are problems with accuracy and these assessments do not always translate into successful risk management.

Objectives

Our aim was to improve the accuracy of assessment and identify risk factors that are causal to be targeted by clinicians to ensure good risk management. Our objectives were to investigate key risks at the population level, construct new static and dynamic instruments, test validity and construct new models of risk management using Bayesian networks.

Methods and results

We utilised existing data sets from two national and commissioned a survey to identify risk factors at the population level. We confirmed that certain mental health factors previously thought to convey risk were important in future assessments and excluded others from subsequent parts of the study. Using a first-episode psychosis cohort, we constructed a risk assessment instrument for men and women and showed important sex differences in pathways to violence. We included a 1-year follow-up of patients discharged from medium secure services and validated a previously developed risk assessment guide, the Medium Security Recidivism Assessment Guide (MSRAG). We found that it is essential to combine ratings from static instruments such as the MSRAG with dynamic risk factors. Static levels of risk have important modifying effects on dynamic risk factors for their effects on violence and we further demonstrated this using a sample of released prisoners to construct risk assessment instruments for violence, robbery, drugs and acquisitive convictions. We constructed a preliminary instrument including dynamic risk measures and validated this in a second large data set of released prisoners. Finally, we incorporated findings from the follow-up of psychiatric patients discharged from medium secure services and two samples of released prisoners to construct Bayesian models to guide clinicians in risk management.

Conclusions

Risk factors for violence identified at the population level, including paranoid delusions and anxiety disorder, should be integrated in risk assessments together with established high-risk psychiatric morbidity such as substance misuse and antisocial personality disorder. The incorporation of dynamic factors resulted in improved accuracy, especially when combined in assessments using actuarial measures to obtain levels of risk using static factors. It is important to continue developing dynamic risk and protective measures with the aim of identifying factors that are causally related to violence. Only causal factors should be targeted in violence prevention interventions. Bayesian networks show considerable promise in developing software for clinicians to identify targets for intervention in the field. The Bayesian models developed in this programme are at the prototypical stage and require further programmer development into applications for use on tablets. These should be further tested in the field and then compared with structured professional judgement in a randomised controlled trial in terms of their effectiveness in preventing future violence.

Pathways through care of severely mentally ill individuals experiencing multiple public crisis events: a qualitative description

BACKGROUND

Patients experiencing severe mental illnesses (SMI) need continuing support and remain vulnerable in many domains. Crisis interventions and compulsory admissions are common, causing a huge burden on police, health workers, the community and patients. The aim of this retrospective case-file study is to determine profiles of SMI-patients and their pathways through care among those experiencing multiple public crisis events.

METHODS

Data from a larger study of 323 SMI-patients in Amsterdam were used. These data were linked to data of the public mental health care (PMHC) in order to identify persons that experienced crisis interventions (CI's) between January 2004 and November 2012. The cut-off point for inclusion in the study population was set on three CI's, resulting in a group of 47 SMI-patients. PMHC and mental health care (MHC) data were linked in order to identify profiles in patterns of care. Qualitative content analysis was used to gather and analyze chronological timelines.

RESULTS

Three profiles were identified: SMI-patients with CI's during continuous MHC, SMI-patients with CI's after discharge and SMI-patients with CI's during unstable MHC. For each profile events prior to, during and after a CI were identified.

CONCLUSIONS

PMHC and MHC can possibly identify cases with a high risk of CI's and predict these events based on the results of this study. CI's seem inevitable for a group of SMI-patients in care but they do not only require acute psychiatric care. The collaboration between MHC, PMHC and police could be further developed in a quick and effective triage in order to tackle the complexity of problems of the SMI-patients.

Improving Quality of Emergency Care Through Integration of Mental Health

The goal of this study was to better integrate emergency medical and psychiatric care at a large urban public hospital, identify impact on quality improvement metrics, and reduce healthcare cost. A psychiatric fast track service was implemented as a quality improvement initiative. Data on disposition from the emergency department from January 2011 to May 2012 for patients impacted by the pilot were analyzed. 4329 patients from January 2011 to August 2011 (pre-intervention) were compared with 4867 patients from September 2011 to May 2012 (intervention). There was a trend of decline on overall quality metrics of time to triage and time from disposition to discharge. The trend analysis of the psychiatric length of stay and use of restraints showed significant reductions. Integrated emergency care models are evidence-based approach to ensuring that patients with mental health needs receive proper and efficient treatment. Results suggest that this may also improve overall emergency department's throughput.

The management of adult psychiatric emergencies in low-income and middle-income countries: a systematic review

The aim of this Review is to identify effective interventions and treatment guidelines to manage common types of psychiatric emergencies in non-specialist settings in low-income and middle-income countries. Mental health specialist services in low-income and middle-income countries are scarce. We did a systematic review of interventions for psychiatric emergencies and a literature search for low-income and middle-income-specific treatment guidelines for psychiatric emergencies. A dearth of high-quality guidelines and contextualised primary evidence for management of psychiatric emergencies in low-income and middle-income countries exists. Filling these gaps in present guidelines needs to be an urgent research priority in view of the adverse health and social consequences of such presentations and the present drive to scale up mental health care.

Difficult behaviors in the emergency department: a cohort study of housed, homeless and alcohol dependent individuals

Background

This study contrasted annual rates of difficult behaviours in emergency departments among cohorts of individuals who were homeless and low-income housed and examined predictors of these events.

Methods

Interviews in 1999 with men who were chronically homeless with drinking problems (CHDP) (n = 50), men from the general homeless population (GH) (n = 61), and men residing in low-income housing (LIH) (n = 58) were linked to catchment area emergency department records (n = 2817) from 1994 to 1999. Interview and hospital data were linked to measures of difficult behaviours.

Results

Among the CHDP group, annual rates of visits with difficult behaviours were 5.46; this was 13.4 (95% CI 10.3–16.5) and 14.3 (95% CI 11.2–17.3) times higher than the GH and LIH groups. Difficult behaviour incidents included physical violence, verbal abuse, uncooperativeness, drug seeking, difficult histories and security involvement. Difficult behaviours made up 57.54% (95% CI 55.43–59.65%), 24% (95% CI 19–29%), and 20% (95% CI 16–24%) of CHDP, GH and LIH visits. Among GH and LIH groups, 87% to 95% were never involved in verbal abuse or violence. Intoxication increased all difficult behaviours while decreasing drug seeking and leaving without being seen. Verbal abuse and violence were less likely among those housed, with odds ratios of 0.24 (0.08, 0.72) and 0.32 (0.15, 0.69), respectively.

Conclusions

Violence and difficult behaviours are much higher among chronically homeless men with drinking problems than general homeless and low-income housed populations. They are concentrated among subgroups of individuals. Intoxication is the strongest predictor of difficult behaviour incidents.

Utilization of behavioral health outpatient therapy and psychiatry services among homeless people recently hospitalized for a psychiatric condition

A database (n = 1698) at a homeless health care center was used to assess factors associated with a psychiatric hospitalization and subsequent behavioral health outpatient therapy and psychiatry visit adherence. Blacks and those recently incarcerated were less likely to report a psychiatric hospitalization and those with a co-occurring disorder or disability were more likely to report a hospitalization. Of those hospitalized, blacks and those with bipolar disorder were less likely to be high adherers to behavioral health outpatient therapy and those incarcerated 4 to 6 months prior to intake were more likely not to attend behavioral health outpatient therapy. Men were at risk for not keeping psychiatry visits.

Adherence to behavioral therapy and psychiatry visits in a safety-net setting in Virginia, USA

Little is known about predictors of adherence to outpatient behavioural therapy and psychiatry visits in those who experience homelessness. Yet, consistent receipt of services in the community is critical to preventing use of acute care psychiatric services, which cause a significant cost burden to the mental health system. This retrospective study examined sociodemographic, housing instability and health-related factors associated with adherence to behavioural therapy and psychiatry appointments among 1711 clients served by an urban healthcare for the homeless centre in Virginia, USA. Clients ≥18 years old with a behavioural health condition who had an intake assessment and at least one behavioural therapy or psychiatry appointment scheduled during October 2005-September 2009 were eligible for the study. Of those with scheduled behavioural therapy visits, 27.7% were high adherers and 19.3% did not attend any appointments, whereas of those with scheduled psychiatry visits, 13.6% were high adherers and 22.1% did not attend any appointments. African Americans, when compared with whites, and those with a primary diagnosis of bipolar disorder were less likely to be high adherers to behavioural therapy. Women and being ≥35 years old were associated with a decreased likelihood of failing to attend psychiatry appointments, whereas African Americans, when compared with whites, and those with co-occurring disorders were more likely to not attend any psychiatry appointments. Understanding factors related to adherence to behavioural health services can help homeless care providers tailor strategies for improving visit adherence.

Prevalence, patterns, and correlates of co-occurring substance use and mental disorders in the United States: variations by race/ethnicity

OBJECTIVE

This study examines racial/ethnic differences in the prevalence, patterns, and correlates of co-occurring substance use and mental disorders (COD) among Whites, Blacks, Latinos, and Asians using data from the Collaborative Psychiatric Epidemiology Studies.

METHOD

We first estimated the prevalence of various combinations of different co-occurring depressive and anxiety disorders among respondents with alcohol, drug, and any substance use (alcohol or drug) disorders in each racial/ethnic group. We then estimated the prevalence of different patterns of onset and different psychosocial correlates among individuals with COD of different racial/ethnic groups. We used weighted linear and logistic regression analysis controlling for key demographics to test the effect of race/ethnicity. Tests of differences between specific racial/ethnic subgroups were only conducted if the overall test of race was significant.

RESULTS

Rates of COD varied significantly by race/ethnicity. Approximately 8.2% of Whites, 5.4% of Blacks, 5.8% of Latinos, and 2.1% of Asians met criteria for lifetime COD. Whites were more likely than persons in each of the other groups to have lifetime COD. Irrespective of race/ethnicity, most of those with COD reported that symptoms of mental disorders occurred before symptoms of substance use disorders. Only rates of unemployment and history of psychiatric hospitalization among individuals with COD were found to vary significantly by racial/ethnic group.

CONCLUSIONS

Our findings underscore the need to further examine the factors underlying differences between minority and nonminority individuals with COD as well as how these differences might affect help seeking and utilization of substance abuse and mental health services.

Missing link in community psychiatry: When a patient with schizophrenia was expelled from her home

Treatment and disposition of homeless patients with schizophrenia represent a great challenge in clinical practice. We report a case of this special population, and discuss the development of homelessness, the difficulty in disposition, their utilization of health services, and possible applications of mandatory community treatment in this group of patients. A 51-year-old homeless female was brought to an emergency department for left femur fracture caused by an assault. She was diagnosed with schizophrenia about 20 years ago but received little help from mental health services over the decades. During hospitalization, her psychotic symptoms were only partially responsive to treatment. Her family refused to handle caretaking duties. The social welfare system was mobilized for long-term disposition. Homeless patients with schizophrenia are characterized by family disruption, poor adherence to health care, and multiple emergency visits and hospitalization. We hope this article can provide information about the current mental health policy to medical personnel. It is possible that earlier intervention and better outcome can be achieved by utilizing mandatory community treatment in the future, as well as preventing patients with schizophrenia from losing shelters.

Aggressive behaviors in the psychiatric emergency service

Introduction:

Studies of aggressive behaviors in a nonforensic mental health setting have focused primarily on the inpatient ward and, on event prediction, using behavior-based clinical rating scales. Few studies have specifically targeted aggressive behaviors in the psychiatric emergency service or determined whether assessing the demographic and clinical characteristics of such patients might prove useful for their more rapid identification.

Methods:

We used a prospectively acquired database of over 20,900 visits to four services in the province of Quebec, Canada, over a two-year period from September 2002 onwards. A maximum of 72 variables could be acquired per visit. Visits with aggression (any verbally or physically intimidating behavior), both present and past, were tagged. Binary logistic regressions and cross-tabulations were used to determine whether the profile of a variable differed in visits with aggression from those without aggression.

Results:

About 7% of visits were marked by current aggression (verbal 49%, physical 12%, verbal and physical 39%). Including visits with a “past only” history of aggression increased this number to 20%. Variables associated with aggression were gender (male), marital status (single/separated), education (high school or less), employment (none), judicial history (any type), substance abuse (prior or active), medication compliance (poor), type of arrival to psychiatric emergency services (involuntary, police, judiciary, landlord), reason for referral (behavioral dyscontrol), diagnosis (less frequent in anxiety disorders), and outcome (more frequently placed under observation or admitted).

Conclusion:

Our results suggest that many state-independent variables are associated with aggressive behaviors in the psychiatric emergency service. Although their sum may not add up to a specific patient profile, they can nevertheless be useful in service planning, being easily integrated alongside state-dependent rating scales in a triage and/or observation instrument for daily use in the psychiatric emergency service.

Factors associated with use of urban emergency departments by the U.S. homeless population

OBJECTIVE

Homeless individuals frequently use emergency departments (EDs), but previous studies have investigated local rather than national ED utilization rates. This study sought to characterize homeless people who visited urban EDs across the U.S.

METHODS

We analyzed the ED subset of the National Hospital Ambulatory Medical Care Survey (NHAMCS-ED), a nationally representative probability survey of ED visits, using methods appropriate for complex survey samples to compare demographic and clinical characteristics of visits by homeless vs. non-homeless people for survey years 2005 and 2006.

RESULTS

Homeless individuals from all age groups made 550,000 ED visits annually (95% confidence interval [CI] 419,000, 682,000), or 72 visits per 100 homeless people in the U.S. per year. Homeless people were older than others who used EDs (mean age of homeless people = 44 years compared with 36 years for others). ED visits by homeless people were independently associated with male gender, Medicaid coverage and lack of insurance, and Western geographic region. Additionally, homeless ED visitors were more likely to have arrived by ambulance, to be seen by a resident or intern, and to be diagnosed with either a psychiatric or substance abuse problem. Compared with others, ED visits by homeless people were four times more likely to occur within three days of a prior ED evaluation, and more than twice as likely to occur within a week of hospitalization.

CONCLUSIONS

Homeless people who seek care in urban EDs come by ambulance, lack medical insurance, and have psychiatric and substance abuse diagnoses more often than non-homeless people. The high incidence of repeat ED visits and frequent hospital use identifies a pressing need for policy remedies.

Assault and substance abuse characterize burn injuries in homeless patients

The homeless are at an increased risk for traumatic injury, but little is known about the injury etiology and outcome of homeless persons who sustain burn injuries. In this study, we analyze patient and injury characteristics of homeless persons admitted to a regional burn center. This is a retrospective cohort study of patients admitted to our burn center between 1994 and 2005. A total of 3700 adult patients were admitted during the study period and, of these, 72 (1.9%) were homeless. The cohort of homeless patients was compared with domiciled adult patients admitted during the same time period, analyzing baseline patient and injury characteristics and injury outcomes. Overall, homeless patients had more extensive burn injuries than domiciled patients (17.8% vs 11.2%TBSA, P < .001) and overall longer lengths of hospital stay (22 vs 12 days, P < .001). The homeless population also had significantly higher rates of alcohol (80.6% vs 12.8%, P < .001) and drug abuse (59.4% vs 12.8%, P < .001), history of mental illness (45.2% vs 11.0%, P < .001), and injury by assault (13.9% vs 2.0%, P < .001). Homeless patients tended to have more severe injuries; higher rates of substance abuse and mental illness; increased incidence of assault by burning; and longer lengths of hospital stay. Hospitalization of a homeless patient following injury may provide a unique opportunity to address co-occurring substance abuse and mental illness and approach injury prevention to improve patients' outcomes and reduce injury recidivism.

Perpetration of violence, violent victimization, and severe mental illness: balancing public health concerns

OBJECTIVE

This review examined U.S. empirical studies published since 1990 of the perpetration of violence and of violent victimization among persons with severe mental illness and their relative importance as public health concerns.

METHODS

MEDLINE, PsycINFO, and Web of Science were searched for published empirical investigations of recent prevalence or incidence of perpetration or victimization among persons with severe mental illness. Studies of special populations were included if separate rates were reported for persons with and without severe mental illness.

RESULTS

The search yielded 31 studies of violence perpetration and ten studies of violent victimization. Few examined perpetration and victimization in the same sample. Prevalence rates varied by sample type and time frame (recall period). Half of the studies of perpetration examined inpatients; of these, about half sampled only committed inpatients, whose rates of perpetration (17%-50%) were higher than those of other samples. Among outpatients, 2% to 13% had perpetrated violence in the past six months to three years, compared with 20% to 34% who had been violently victimized. Studies combining outpatients and inpatients reported that 12% to 22% had perpetrated violence in the past six to 18 months, compared with 35% who had been a victim in the past year.

CONCLUSIONS

Perpetration of violence and violent victimization are more common among persons with severe mental illness than in the general population. Victimization is a greater public health concern than perpetration. Ironically, the discipline's focus on perpetration among inpatients may contribute to negative stereotypes.

Collaborative mental health care for the homeless: the role of psychiatry in positive housing and mental health outcomes

OBJECTIVE

Factors associated with positive outcomes for homeless men referred to a shelter-based collaborative mental health care team were examined.

METHOD

A chart review of 73 clients referred over 12 months was completed. Two outcome measures were examined, clinical status and housing status, 6 months after their referral to the program.

RESULT

Among the referred clients, the prevalence of severe and persistent mental illness and substance use disorders was 76.5% and 48.5%, respectively. At 6 months, 24 clients (35.3%) had improved clinically, and 33 (48.5%) were housed. Logistic regression identified 2 factors associated with clinical improvement: the number of visits with a psychiatrist and treatment adherence. The same 2 factors were associated with higher odds of housing, and presence of substance use disorder was associated with lower odds of housing at 6-month follow-up.

CONCLUSION

Care by a mental health specialist is positively associated with improved outcomes. Strategies to improve treatment adherence, access to mental health specialists, and innovative approaches to treatment of substance use disorders should be considered for this population. Having a psychiatrist as a member of a shelter-based collaborative care team is one possible way of addressing the complex physical and mental health needs of homeless individuals.

Utilization of psychiatric emergency services by homeless persons in Spain

OBJECTIVE

Studies examining the relationship between homeless persons and the use of psychiatric emergency services (PES) in a country with universal access to health care are lacking. This study aimed to determine the prevalence of homelessness in adults visiting a PES in Spain, identify the differences between homeless and non-homeless patients in the use of PES and analyze the factors associated with homelessness and the decision to hospitalize.

METHOD

The study included a total of 11 578 consecutive admissions to a PES in a tertiary hospital in Barcelona, Spain, over a 4-year period. Data collected included socio-demographic and clinical information, and score on the Severity of Psychiatric Illness (SPI) scale. Multivariate logistic regression analyses were used to calculate odds ratios for the factors associated with homelessness and the decision to hospitalize.

RESULTS

Five hundred sixty (4.8%) admissions were considered homeless. Homeless patients had more psychotic and drug abuse disorders, greater severity of symptoms, more risk of being a danger to others and more frequent hospitalization needs than non-homeless patients. Factors related to homelessness were male gender, substance abuse and immigrant status from North Africa, Sub-Sahara Africa and Western countries. The decision to hospitalize homeless patients was associated with psychosis diagnosis, suicide risk, danger to others, symptom severity, medical problems and noncompliance with treatment.

CONCLUSIONS

In an attempt to decrease the use of emergency resources and prevent the risk of homelessness, mental health planners in a universal healthcare system should improve outpatient access for populations with risk factors such as substance abuse and immigration.

Housing First for Long-Term Shelter Dwellers with Psychiatric Disabilities in a Suburban County: A Four-Year Study of Housing Access and Retention

Housing First is an effective intervention that ends and prevents homelessness for individuals with severe mental illness and co-occurring addictions. By providing permanent, independent housing without prerequisites for sobriety and treatment, and by offering support services through consumer-driven Assertive Community Treatment teams, Housing First removes some of the major obstacles to obtaining and maintaining housing for consumers who are chronically homeless. In this study, consumers diagnosed with severe mental illness and who had the longest histories of shelter use in a suburban county were randomly assigned to either one of two Housing First programs or to a treatment-as-usual control group. Participants assigned to Housing First were placed in permanent housing at higher rates than the treatment-as-usual group and, over the course of four years, the majority of consumers placed by both Housing First agencies were able to maintain permanent, independent housing. Results also highlight that providers new to Housing First must be aware of ways in which their practices may deviate from the essential features of Housing First, particularly with respect to enrolling eligible consumers on a first-come, first-served basis and separating clinical issues from tenant or housing responsibilities. Finally, other aspects of successfully implementing a Housing First program are discussed.

Health care needs of homeless adults at a nurse-managed clinic

Up to 55% of the homeless population report health problems. They often use the emergency department (ED) to obtain care when the health needs are not urgent. Nurse-managed clinics have the potential to reduce nonurgent ED use and improve the health of the homeless. The purpose of this study was to establish baseline health data on homeless persons prior to attending a nurse-managed clinic.(1) This study was a cross-sectional, retrospective health survey of homeless clients at a nurse-managed clinic. A total of 110 participants completed a baseline health survey. Of these, 61% reported that prior to coming to the clinic, they used the ED as a source of health care. The most frequent medical diagnoses reported were substance use disorders, depression, back pain, hypertension, and asthma. Providing care for chronic conditions at a nurse-managed clinic has the potential to improve health and reduce use of the ED.

Psychotic disorders among homeless subjects attending a psychiatric emergency service

BACKGROUND

Homelessness is an increasing problem among subjects with severe mental illnesses and little is known about the characteristics of homeless subjects with psychosis using emergency psychiatric services. The aims of the present study were to assess the frequency of psychotic disorders among subjects attending a psychiatric emergency service and to explore the clinical and demographic characteristics of these subjects and the management proposed by the emergency staff.

METHODS

All homeless patients (n=104) consecutively attending a psychiatric emergency service were included over a 6-month period. Patients were categorised according to ICD-10 diagnoses as presenting with psychotic disorder (schizophrenia and other non-affective psychotic disorders) versus other disorders. A random sample of matched non-homeless controls (n=71) was included over the same period.

RESULTS

Nearly one out of three homeless subjects (32.7%) presented with a psychotic disorder, a higher proportion than that found in non-homeless subjects (15.7%). Compared to non-homeless subjects with psychosis, homeless subjects with psychosis were more likely to be male and to present with drug use disorder. The likelihood of being hospitalised after attending the psychiatric emergency services did not significantly differ between the two groups. Compared to homeless subjects with other psychiatric disorders, homeless subjects with psychosis were more likely to be single, to have a history of psychiatric hospitalisation and presented less frequently with anxiety or depressive symptoms motivating admission.

CONCLUSION

Most homeless subjects with psychosis attending a psychiatric emergency service were already identified as suffering from a severe mental illness, suggesting that homelessness was a consequence of a break in contact with mental health services. Since homelessness is incompatible with the adequate management of psychosis, strategies have to be developed in mental health organisations in combination with outside partnerships, to drastically reduce the frequency of this condition in subjects with psychosis.

Suicide in the homeless within 12 months of contact with mental health services : a national clinical survey in the UK

BACKGROUND

Suicide prevention is a health service priority. Homeless mental health patients present a challenge to services because of their complex health and social needs.

AIMS

To establish the numbers of homeless patients in contact with services who die by suicide; to describe their suicide methods and their social and clinical characteristics including aspects of clinical care.

METHOD

A national clinical survey based on a 4-year (1996-2000) sample of people in England and Wales who died by suicide. Detailed data were collected on those who had been in contact with mental health services in the year before death.

RESULTS

A total of 131 individuals who died by suicide were reported to have been homeless at the time of death--3% of all suicides by psychiatric patients, over 30 per year. Hanging was the most common cause of death. The most frequent diagnosis was schizophrenia. Around half were in-patients at the time of death. Social and clinical risk factors for suicide were common, including drug and alcohol misuse, and recent suicidal ideas and behaviour. Despite this, their clinical care was characterised by disengagement from services as a result of missed contacts, self-discharge, lack of follow-up and lack of key worker.

CONCLUSIONS

In order to reduce the number of deaths by suicide in those who are homeless and mentally ill, improvements in in-patient safety and engagement in the community are needed. This may be achieved through assertive community treatment, dual diagnosis services, and dedicated community mental health teams.

Perceived impact by administrators of psychiatric emergency services after changes in a state's mental health system

As a safety net, psychiatric emergency services are sensitive to system changes. To determine the impact of a state's changes in its mental health system, administrators of publicly funded psychiatric emergency services were surveyed. They reported few (M=0.8) negative changes in coordination of care but 77% endorsed change in administrative burden (54% saying it negatively affected quality of services). Reporting negative effect of administrative burden was associated with treating more persons with substance abuse problems and greater challenge posed by distance to local providers. These results suggest that impact of state-level changes was not uniform but associated with local characteristics.
