Predictors of emergency room use by homeless adults in New York City: the influence of predisposing, enabling and need factors

An Integrative Model of ENT Healthcare for the Homeless Population

OBJECTIVE

Our aim was to determine the need for otolaryngology care within the homeless population, identify barriers to access that the homeless population may face, and develop a model system which would address these needs with respect to the barriers.

METHODS

A retrospective chart review of 812 patients seen between 1/25/16-3/21/2020 was performed. Charts were obtained from homeless patients seen at free general clinics held shelters in Chicago, IL (781 charts) and in Champaign, IL (31 charts). Records reporting at least one otolaryngology disease in a patient experiencing homelessness were included in this study. Patients were considered homeless if they resided at the shelter at the time of their appointment. To determine common barriers to care, a simple yes/no questionnaire was administered to residents at west-side Chicago homeless shelters. Questions addressed barriers to health care access that had been mentioned by patients seen at free clinics.

RESULTS

Chart review findings demonstrated that 14.3% (n = 142) of all homeless patients seen at free in-shelter clinics were seen for ENT-related disorders. Survey results revealed that 76.3% (n = 71) of respondents believed that telemedicine services would be useful in shelters. 74.2% (n = 69) stated they were unable to afford prescribed medications. 93.5% (n = 87) stated that better access to transportation would increase their likelihood of seeking care.

CONCLUSIONS

In our attempt to bridge this inequity, we have launched a hybrid in-person/virtual care program to improve access to otolaryngology care for the homeless community.

Schizoaffective disorder in homeless patients: A systematic review

BACKGROUND

Schizoaffective psychosis is a severe and chronic psychiatric disorder defined by the presence of mood symptoms, like mania and/or depression and schizophrenia, such as hallucinations and/or delusions.

AIMS

We aim to find out whether there is a correlation between schizoaffective psychosis and being homeless.

METHOD

To do so, a literature search was carried out in the PubMed platform in April 2022, using the keywords 'schizoaffective' and 'homeless'.

RESULTS

In this review, 28 articles from this search were included. Intrinsic characteristics, rates of psychiatric readmission, prediction of homelessness, medication noncompliance, and substance use were explored, as they were the main themes of the results.

CONCLUSIONS

The homeless population suffers from great diagnostic variability and the diagnosis schizoaffective psychosis is still evolving contributing to such diagnostic and treatment difficulties. Their frequent visits to the healthcare services, especially emergency room leads to consequent interaction with multiple healthcare professionals, resulting in a myriad of diagnoses, with clinical remission and therapeutic goals not being attained. More studies are necessary for a better evaluation of this super difficult population.

Individuals Experiencing Homelessness: A Systematic Review of Otolaryngology-Related Health Needs and Community-Based Interventions

OBJECTIVE

Access to and use of physician services is limited for those experiencing homelessness. Homelessness may predispose patients to several Otolaryngology-Head and Neck Surgery (OHNS) health conditions and barriers to care may leave these unaddressed. The aim of this review was to synthesize the literature on OHNS health needs and community-based interventions for patients experiencing homelessness.

DATA SOURCES

English literature was searched in MEDLINE, EMBASE, and CINAHL.

REVIEW METHODS

Studies were included if they reported on OHNS-related conditions in patients experiencing homelessness and/or interventions related to providing OHNS care to this patient population.

RESULTS

Twelve hundred and one articles were screened, and 12 articles were included. Most studies reported on otologic conditions (n = 8) and head and neck-related conditions (n = 6). Nasal trauma, chronic rhinosinusitis, dysphonia, hearing loss, and cancerous/precancerous head and neck lesions were common OHNS conditions reported in this patient population. Identified barriers to care included lack of transportation, financial considerations, and lower health literacy. Three articles on community-based interventions were included. Most of these interventions were single visits to shelters, and ensuring adequate follow-up was identified as a challenge.

CONCLUSION

The current literature brings attention to certain OHNS diseases that are prevalent in this unique patient population and identifies unique barriers these patients experience when accessing care. Future studies should focus on further delineating the impact of OHNS diseases in patients experiencing homelessness and screening interventions that can be employed to mitigate the impact of diseases of the head and neck.

Assessing psychosocial distress associated with homelessness in Ghana: A springboard for interventional policy design

This study investigated the causes of homelessness in Ghana and associated psychosocial distress. A sample of 86 homeless participants listed perceived causes of their homelessness and completed measures of psychosocial distress, and 97 non-homeless participants completed the same measures psychosocial distress. Causes of homelessness among the participants included poverty (30.1%), migration (10.4%), unemployment (2.2%), parental demise (2.2%), parental neglect (0.5%), and parental divorce (0.5%). Multivariate analysis revealed higher psychosocial distress among the homeless than the non-homeless. Homeless females reported higher levels of stress and suicidality than their male counterparts. The study demonstrates the need for timely and effective implementation of interventions such as provision of affordable housing, financial assistance, job-creation, and skill training for the homeless directly related to known causes of homelessness and accounting for gender differences.

Health Service Access Among Homeless Veterans: Health Access Challenges Faced by Homeless African American Veterans

Veteran homelessness is a public health crisis, especially among the disproportionate number of minority veterans in the homeless veteran population. African American homeless veterans in particular face unique challenges accessing appropriate health care services to meet their medical needs. Their needs are often underrepresented in the literature on veteran homelessness. Drawing together over 80 studies and government reports from the last two decades, this review provides a timely synopsis of homeless veterans' health care access, with a particular focus on the barriers faced by African American veterans. This review employs Penchansky and Thomas' Access Model to frame health access barriers faced by homeless veterans, dialing in on what is known about the experience of African American veterans, within the five dimensions of access: Availability, Accessibility, Accommodation, Affordability, and Acceptability. Actionable guidance and targeted interventions to address health access barriers for all veterans are delineated with a focus on the need to gather further data for African American homeless veterans and to consider tailoring interventions for this important and underserved group.

Migration Patterns from an Open Illicit Drug Scene and Emergency Department Visits among People Who Use Illicit Drugs in Vancouver, Canada

BACKGROUND

People who use illicit drugs (PWUD) experience various adverse health outcomes leading to increased healthcare service utilization. PWUD are also a highly mobile population which poses challenges to healthcare delivery. The objective of this study was to identify migration patterns from the Downtown Eastside (DTES), an urban illicit drug scene in Vancouver and to estimate the impact of different migration patterns on two outcomes: a) emergency department (ED) visits and b) ED visits resulting in inpatient admission among PWUD.

METHODS

Three prospective cohorts of PWUD in Vancouver were linked with regional ED data. We defined the optimal number of trajectory groups that best represented distinct patterns of migration from Vancouver's DTES using a latent class growth analysis. Then, generalized estimating equations were used to estimate the effect of migration patterns on the two ED outcomes.

RESULTS

Four distinct migration trajectory patterns were identified among the 1210 included participants: PWUD who consistently lived in the DTES, those who migrated out of DTES early, those who migrated out of DTES late, and those who frequently revisited the DTES. Participants who frequently revisited the DTES had higher odds of an ED visit (adjusted odds ratio = 1.62; 95% confidence interval: 1.28-2.06). There was no significant association between migration patterns and inpatient admission.

CONCLUSIONS

We found that PWUD who frequently revisited the DTES were more likely to have utilized the ED, suggesting that there may be a subgroup of PWUD who are at increased risk of experiencing negative health outcomes.Supplemental data for this article is available online at 10.1080/10826084.2021.1958849.

Predictors of Overnight and Emergency Treatment among Homeless Adults

High usage of emergency treatment and hospitalization has been reported among homeless individuals. Hence, this study aimed to identify the sociodemographic predictors associated with overnight and emergency hospital treatment among a sample of homeless adults. Participants were recruited from a shelter in Dallas, Texas (N = 354; Mage = 43.7 ± 11.7) and were predominantly uninsured, low-income men from various racial groups. The outcome variables were: (a) stayed overnight for treatment in a hospital; and (b) treated in a hospital emergency room. In logistic regression models, sex emerged as the only predictor of overnight treatment in a hospital (OR = 2.68, 95% CI = 1.61-4.47), and treatment in an emergency room (OR = 2.21, 95% CI = 1.34-3.65), such that women were more likely than men to be treated overnight and use emergency care. Targeted interventions and policies are needed to address homeless women's primary care needs and reduce costlier treatment.

Cardiovascular Disease and Homelessness

Cardiovascular disease (CVD) is a major cause of death among homeless adults, at rates that exceed those in nonhomeless individuals. A complex set of factors contributes to this disparity. In addition to a high prevalence of cigarette smoking and suboptimal control of traditional CVD risk factors such as hypertension and diabetes, a heavy burden of nontraditional psychosocial risk factors like chronic stress, depression, heavy alcohol use, and cocaine use may confer additional risk for adverse CVD outcomes beyond that predicted by conventional risk estimation methods. Poor health care access and logistical challenges to cardiac testing may lead to delays in presentation and diagnosis. The management of established CVD may be further challenged by barriers to medication adherence, communication, and timely follow-up. The authors present practical, patient-centered strategies for addressing these challenges, emphasizing the importance of multidisciplinary collaboration and partnership with homeless-tailored clinical programs to improve CVD outcomes in this population.

Duration of homelessness and its relationship to use of hospital and emergency department services in Helsinki, Finland

Aims: Homelessness is associated with poor health outcomes and increased use of hospital and emergency department (ED) services. Little is known about the duration of homelessness in relation to health care service use. The aim of this study was to examine the use of hospital and ED services among the homeless in Helsinki, Finland, and for the first time, to examine the relationship between service use and duration of homelessness. Methods: Six hundred and eighty-three persons staying at least one night in a shelter between September 2009 and September 2010 were followed until the end of 2014. Using negative binominal regression analysis we calculated the use of hospital and ED services and compared the use with that of a matched control group (N = 1361). We also analyzed service use in relation to the time spent homeless during follow-up. Results: The mean time spent homeless during the follow-up was 8.5 months, one third was temporarily homeless (less than 2% of the follow-up time), but recurrent episodes of homelessness were also common. The study group's incidence rate ratios for medical-surgical hospital days was 6.23 (95% CI: 4.73 to 8.21), for psychiatric hospital days 43.11 (95% CI: 23.02 to 80.74) and for ED visits 10.21 (95% CI: 8.77 to 11.90), compared with controls. The number of medical-surgical hospital days and ED visits/person-year increased as homelessness was prolonged, but the pattern was opposite for psychiatric hospital days. Conclusions: Homeless persons are heavy users of hospital and ED services, and there is also increased use among those temporarily homeless.

Factors associated with healthcare utilization among community-dwelling elderly in Shanghai, China

OBJECTIVE

The objective of this study was to evaluate the factors associated with the health status of older Chinese people living in the community, in order to inform strategies to expand access to healthcare.

METHODS

Two-phase stratified cluster sampling was applied; 2000 older people participated in this study. Face-to-face interviews were conducted in Shanghai between June and August, 2011. Descriptive analysis was used to examine the respondents' characteristics. Based on Andersen's healthcare utilization model, a chi-squared test and multiple logistic regression were performed to examine the influences of predisposing, enabling, need, and contextual factors on healthcare utilization.

RESULTS

We found that 44.5% of the older people in the sample had good self-reported health status, while 12.8% were poor, 14.5% had visited hospitals or clinics as outpatients in the previous two weeks, and 16.5% had been hospitalized in the previous year. Logistic regression analysis revealed that outpatient health services were more likely to be used by women and those whose income was from friends or social relief, who had poor to good self-reported health status, who were experiencing declining health, who engaged in volunteer activities, and who had chronic diseases. Meanwhile, hospitalization was more likely among those in the older age groups, those with pension income, living in outer suburbs, with poor self-reported health status, experiencing difficulty with activities of daily living and outdoor activities, or having a chronic disease.

CONCLUSIONS

The results showed the impact of economic status, health status, demographic and social characteristics, and other factors on the health service utilization of elderly people living in the community in Shanghai. Need variables were the strongest predictors of health service use, although contextual factors also contributed.

Comprehensive services delivery and emergency department use among chronically homeless adults

Homeless adults use emergency department (ED) services more frequently than other adults, but the relationships between homelessness, health status, outpatient service use, and ED utilization are poorly understood. Data from the Collaborative Initiative to Help End Chronic Homelessness (CICH) were used to compare ED use among chronically homeless adults receiving comprehensive housing, case management, mental health, addiction, and primary care services through CICH at 5 U.S. sites (n = 274) and ED use among comparison group clients receiving generally available community services (n = 116) at the same sites. Multiple imputation was used to account for missing data and differential rates of attrition between the cohorts. Longitudinal models were constructed to compare ED use between the 2 groups during the first year after initiation of CICH services. A mediation analysis was performed to determine the relative contributions of being housed, the receipt of outpatient services, and health status to group differences in ED utilization. Participants receiving CICH services were significantly less likely to report ED use (odds ratio = 0.78, 95% confidence interval [0.65, 0.93]) in the year after program entry. Decreased ED use was primarily mediated by decreased homelessness-not by increased access to other services or health status. This suggests that becoming housed is a key driver of reduced ED utilization and that efforts to provide housing for homeless adults may result in significantly decreased ED use. Further research is needed to determine the long-term effects of housing on health status and to develop services to improve health outcomes. (PsycINFO Database Record

Characteristics of frequent emergency department users with type 2 diabetes mellitus in Korea

AIMS/INTRODUCTION

Frequent emergency department (ED) visitors are medically vulnerable individuals. We identified the characteristics of "frequent ED users" among Korean patients with type 2 diabetes mellitus.

MATERIALS AND METHODS

We used the Health Insurance Review and Assessment Service National Patient Sample, which is a nationally representative sample. Patients (n = 109,412) with type 2 diabetes mellitus as a primary or secondary diagnosis at one of their visits were included. Individuals were classified into three groups according to the number of ED visits: frequent (≥4 visits), occasional (<4 visits) and non-users of the ED. The characteristics of the patients that distinguished frequent users from the other groups were investigated.

RESULTS

Frequent ED users were mainly men (P < 0.001), with longer treatment duration (P < 0.001), more frequent comorbidities (cardiovascular and chronic kidney disease) and primary diagnosis made by surgery (P = 0.0028). They had higher mortality (P = 0.0085), longer hospitalization duration (P < 0.001), higher costs per visit (P < 0.001) and more often required medical protection (P < 0.001). These patients were treated more frequently with sulfonylurea, insulin, meglitinide and alpha-glucosidase inhibitors (P < 0.05).

CONCLUSIONS

The present findings suggest that frequent users of the ED with type 2 diabetes mellitus have serious health conditions, a poor socioeconomic situation and tend to take some medicines (sulfonylurea, etc.), which often are associated with hypoglycemia. Attention should be given to therapy, and to patients with renal and cardiovascular diseases to decrease the dependency of these patients on the ED.

Usage of unscheduled hospital care by homeless individuals in Dublin, Ireland: a cross-sectional study

OBJECTIVES

Homeless people lack a secure, stable place to live and experience higher rates of serious illness than the housed population. Studies, mainly from the USA, have reported increased use of unscheduled healthcare by homeless individuals.We sought to compare the use of unscheduled emergency department (ED) and inpatient care between housed and homeless hospital patients in a high-income European setting in Dublin, Ireland.

SETTING

A large university teaching hospital serving the south inner city in Dublin, Ireland. Patient data are collected on an electronic patient record within the hospital.

PARTICIPANTS

We carried out an observational cross-sectional study using data on all ED visits (n=47 174) and all unscheduled admissions under the general medical take (n=7031) in 2015.

PRIMARY AND SECONDARY OUTCOME MEASURES

The address field of the hospital's electronic patient record was used to identify patients living in emergency accommodation or rough sleeping (hereafter referred to as homeless). Data on demographic details, length of stay and diagnoses were extracted.

RESULTS

In comparison with housed individuals in the hospital catchment area, homeless individuals had higher rates of ED attendance (0.16 attendances per person/annum vs 3.0 attendances per person/annum, respectively) and inpatient bed days (0.3 vs 4.4 bed days/person/annum). The rate of leaving ED before assessment was higher in homeless individuals (40% of ED attendances vs 15% of ED attendances in housed individuals). The mean age of homeless medical inpatients was 44.19 years (95% CI 42.98 to 45.40), whereas that of housed patients was 61.20 years (95% CI 60.72 to 61.68). Homeless patients were more likely to terminate an inpatient admission against medical advice (15% of admissions vs 2% of admissions in homeless individuals).

CONCLUSION

Homeless patients represent a significant proportion of ED attendees and medical inpatients. In contrast to housed patients, the bulk of usage of unscheduled care by homeless people occurs in individuals aged 25-65 years.

Demographic and clinical characteristics among Turkish homeless patients presenting to the emergency department

Objective

Since the homeless are at greater risk of encountering health problems than the general population, the reasons for and incidence of their presentations to emergency departments also vary. The purpose of this study was to determine the sociodemographic and clinical characteristics of Turkish homeless patients who brought to the emergency department by ambulance.

Materials and methods

The records of homeless adult patients brought to the ED by 112 emergency service ambulance teams over a 1-year period from January to December, 2014, were examined retrospectively.

Results

Thirty-six (21.56%) of the homeless patients enrolled in the study presented due to trauma, and 131 (78.44%) due to non-traumatic causes. One hundred thirty-seven (82.04%) of the total patient group were male. The mean age of the non-trauma patients was 47.3 ± 15.2 years (range, 18-81 years), and the mean age of the trauma patients was 36.9 ± 14.4 years (range, 18-63 years). The most common reason for presentation among patients presenting to the emergency department for non-trauma reasons was clouded consciousness (n = 39, 23.35%), followed by general impaired condition (n = 26, 15.57%), respiratory difficulty (n = 25 14.97%) and abdominal pain (n = 21, 12.57%). The most common reason for presentation among trauma cases was traffic accidents (n = 13, 7.78%), followed by sharp implement injury (n = 9, 5.39%). Four (2.4%) homeless patients died in the emergency department, three (%1.8) homeless patients discharged from the emergency department, and the remaining 160 (95.8%) were admitted to the hospital.

Conclusion

Homeless patients may present to the emergency department due to traumatic or non-traumatic causes. Admission levels are high among these patients, who may have many acute and chronic problems, and appropriate precautions must be taken in the management of these subjects in the emergency department.

An intensive assessment of alcohol use and emergency department utilization in homeless alcohol-dependent adults

BACKGROUND

Excessive alcohol use among the homeless may contribute to their high rates of emergency department use. Survey-based studies have provided some information on the relation between alcohol and emergency department use among the homeless.

METHODS

This study used an intensive schedule of random breath collections and self-report assessments to examine the relation between emergency department utilization and alcohol use in homeless alcohol-dependent adults. Data were from homeless alcohol-dependent adults (N=116) who were participating in a therapeutic workplace that provided job-skills training every weekday for 26 weeks. Breath-sample collections and assessments of self-reported alcohol use were scheduled each week, an average of twice per week per participant, at random times between 9:00 A.M. and 5:00 P.M. Participants received $35 for each breath sample collected. Self-reports of emergency department use were assessed throughout the study.

RESULTS

Thirty-four percent of participants reported attending an emergency department and reported an average of 2.2 emergency department visits (range 1-10 visits). Alcohol intoxication was the most common reason for emergency department use. Participants who used the emergency department had significantly more alcohol-positive breath samples and more self-reported heavy alcohol use than participants who did not use the emergency department.

CONCLUSIONS

This study provided a rare intensive assessment of alcohol and emergency department use in homeless alcohol-dependent adults over an extended period. Emergency department use was high and was significantly related to indices of alcohol use.

Factors Affecting Emergency Department Use by a Chronically Homeless Population

OBJECTIVE

Homeless adults make extensive use of emergency department (ED) services. This study examined factors associated with moderate and high ED use in a cohort of chronically homeless individuals.

METHODS

A cross-sectional analysis identified factors related to ED use in a cohort of 755 individuals at 11 sites at entry into the Collaborative Initiative to Help End Chronic Homelessness (CICH). Bivariate analyses identified sociodemographic, housing status, health status, and service-related factors associated with moderate and high ED use. Independent risk factors were then identified by using a multivariate multinomial model. Hierarchical regression was used to compare the strengths of association between ED use and blocks of factors composed of sociodemographic, housing, health, and service-related characteristics.

RESULTS

In a three-month period, 30% of participants visited the ED one or two times (moderate ED use) and 12% visited three or more times (high-ED use). ED use was most strongly associated with poor health and utilization of other non-ED services and to a lesser extent with housing status.

CONCLUSIONS

Increased ED utilization was associated with both general medical and psychiatric morbidity and greater use of non-ED services. Thus ED use was related to high need and acuity and was not ameliorated by use of other services. Housing instability and homelessness contributed less robustly to increased ED use. More coordinated services may better address the complex medical, housing, and psychosocial needs of chronically homeless individuals.

Anticipated Choices Among Self-, Informal, and Formal Care by Older Canadians

The present research investigated factors related to the health care choices seniors anticipated making in response to hypothetical illness symptoms (e.g. rectal bleeding). After collecting demographic data, 80 seniors were presented various illness symptoms. Directly following each symptom they were asked whether they anticipated using self-, informal, or formal care to deal with the potential problem. In general, seniors with higher perceived health status anticipated using self-care. Being male and having a lower perceived health status was predictive of choosing informal care, whereas being female was predictive of anticipating using formal care. When individual symptoms were analyzed, additional predictors were identified. Judged seriousness of a symptom, experience with a symptom, and social network status were related to different anticipated health care choices for some, but not all, symptoms. Perhaps the most striking finding was the difference between males and females. Since health status between males and females was not significantly different, this difference in anticipated choice of care seemed to be linked to personal preference rather than health status per se.

Psychopharmacologic Services for Homeless Veterans: Comparing Psychotropic Prescription Fills Among Homeless and Non-Homeless Veterans with Serious Mental Illness

Using national Veterans Health Administration (VHA) administrative data, this study evaluated differences in psychotropic medication use between homeless and non-homeless adults with serious mental illness (SMI) who used VHA services in 2010. The adjusted mean number of psychotropic prescription fills associated with homeless individuals were identified using regression models adjusted for socio-demographics, diagnoses, and use of health services. Of the 876,989 individuals with SMI using VHA services, 7.2 % were homeless at some time during 2010. In bivariate analysis, homeless individuals filled more psychotropic medication prescriptions compared with non-homeless individuals. However, after adjusting for potentially confounding variables, homeless individuals were found to have filled 16.2 % fewer prescriptions than non-homeless individuals when all psychotropics were analyzed together (F = 6947.1, p < .001) and for most individual classes of psychotropics. Greater use of residential/inpatient mental health services by the homeless was the most important single factor associated with filling more psychotropic prescriptions than non-homeless individuals.

Emergency Department Frequent Utilization for Non-Emergent Presentments: Results from a Regional Urban Trauma Center Study

OBJECTIVES

First, to test a model of the drivers of frequent emergency department utilization conceptualized as falling within predisposing, enabling, and need dimensions. Second, to extend the model to include social networks and service quality as predictors of frequent utilization. Third, to illustrate the variation in thresholds that define frequent utilization in terms of the number of emergency department encounters by the predictors within the model.

DATA SOURCE

Primary data collection over an eight week period within a level-1 trauma urban hospital's emergency department.

STUDY DESIGN

Representative randomized sample of 1,443 adult patients triaged ESI levels 4-5. Physicians and research staff interviewed patients as they received services. Relationships with the outcome variable, utilization, were tested using logistic regression to establish odds-ratios.

PRINCIPAL FINDINGS

70.6 percent of patients have two or more, 48.3 percent have three or more, 25.3 percent have four or more, and 14.9 percent have five or more emergency department visits within 12 months. Factors associated with frequent utilization include gender, race, poor mental health, mental health drugs, prescription drug abuse, social networks, employment, perceptions of service quality, seriousness of condition, persistence of condition, and previous hospital admittance.

CONCLUSIONS

Interventions targeting associated factors will change global emergency department encounters, although the mutability varies. Policy interventions to address predisposing factors such as substance abuse or access to mental health treatment as well as interventions that speak to enabling factors such as promoting the resiliency of social networks may result in decreased frequency of emergency department utilization.

Frequent Emergency Department Visits and Hospitalizations Among Homeless People With Medicaid: Implications for Medicaid Expansion

OBJECTIVES

We examined factors associated with frequent hospitalizations and emergency department (ED) visits among Medicaid members who were homeless.

METHODS

We included 6494 Massachusetts Medicaid members who received services from a health care for the homeless program in 2010. We used negative binomial regression to examine variables associated with frequent utilization.

RESULTS

Approximately one third of the study population had at least 1 hospitalization and two thirds had 1 or more ED visits. More than 70% of hospitalizations and ED visits were incurred by only 12% and 21% of these members, respectively. Homeless individuals with co-occurring mental illness and substance use disorders were at greatest risk for frequent hospitalizations and ED visits (e.g., incidence rate ratios [IRRs] = 2.9-13.8 for hospitalizations). Individuals living on the streets also had significantly higher utilization (IRR = 1.5).

CONCLUSIONS

Despite having insurance coverage, homeless Medicaid members experienced frequent hospitalizations and ED visits. States could consider provisions under the Patient Protection and Affordable Care Act (e.g., Medicaid expansion and Health Homes) jointly with housing programs to meet the needs of homeless individuals, which may improve the quality and cost effectiveness of care.

Tailoring Outreach Efforts to Increase Primary Care Use Among Homeless Veterans: Results of a Randomized Controlled Trial

BACKGROUND

Homeless individuals often have significant unmet health care needs that are critical to helping them leave homelessness. However, engaging them in primary and mental health care services is often elusive and difficult to achieve.

OBJECTIVE

We aimed to increase health-seeking behavior and receipt of health care among homeless Veterans.

DESIGN

This was a multi-center, prospective, community-based, two-by-two randomized controlled trial of homeless Veterans.

PARTICIPANTS

Homeless Veterans not receiving primary care participated in the study.

INTERVENTIONS

An outreach intervention that included a personal health assessment and brief intervention (PHA/BI), and/or a clinic orientation (CO) was implemented.

MAIN MEASURE

We measured receipt of primary care within 4 weeks of study enrollment.

KEY RESULTS

Overall, 185 homeless Veterans were enrolled: the average age was 48.6 years (SD 10.8), 94.6% were male, 43.0% were from a minority population, 12.0% were unsheltered, 25.5% were staying in a dusk-to-dawn emergency shelter, 26.1% were in transitional housing, while 27.7% were in an unstable, doubled-up arrangement. At one month, 77.3% of the PHA/BI plus CO group accessed primary care and by 6 months, 88.7% had been seen in primary care. This was followed by the CO-only group, 50.0% of whom accessed care in the first 4 weeks, the PHI/BI-only arm at 41.0% and the Usual Care arm at 30.6%. Chi-squared tests by group were significant (p < 0.001) at both 4 weeks and 6 months. There was no difference in attitudes about care at baseline and 6 months or in use patterns once enrolled in care.

CONCLUSIONS

Our findings suggest that treatment-resistant/avoidant homeless Veterans can be effectively engaged in primary and other clinical care services through a relatively low intensity, targeted and tailored outreach effort.

Accuracy of Self-Reported Health Care Use in a Population-Based Sample of Homeless Adults

OBJECTIVE

To assess the accuracy of self-reported ambulatory care visits, emergency department (ED) encounters, and overnight hospitalizations in a population-based sample of homeless adults.

DATA SOURCE

Self-report survey data and administrative health care utilization databases.

STUDY DESIGN

Self-reported health care use in the past 12 months was compared to administrative encounter records among 1,163 homeless adults recruited in 2004-2005 from shelters and meal programs in Toronto, Ontario.

DATA EXTRACTION METHODS

Self-reported health care use was assessed using a structured face-to-face survey. Each participant was linked to administrative databases using a unique personal health number or their first name, last name, sex, and date of birth.

PRINCIPAL FINDINGS

The sensitivity of self-report for ambulatory care visits, ED encounters, and overnight hospitalizations was 89, 80, and 73 percent, respectively; specificity was 37, 83, and 91 percent. The mean difference between self-reported and documented number of encounters in the past 12 months was +1.6 for ambulatory care visits (95 percent CI = 0.4, 2.8), -0.6 for ED encounters (95 percent CI = -0.8, -0.4), and 0.0 for hospitalizations (95 percent CI = 0.0, 0.1).

CONCLUSIONS

Adults experiencing homelessness are quite accurate reporters of their use of health care, especially for ED encounters and hospitalizations.

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.

Diabetes and hypertension prevalence in homeless adults in the United States: a systematic review and meta-analysis

We estimated hypertension and diabetes prevalence among US homeless adults compared with the general population, and investigated prevalence trends. We systematically searched 5 databases for published studies (1980-2014) that included hypertension or diabetes prevalence for US homeless adults, pooled disease prevalence, and explored heterogeneity sources. We used the National Health Interview Survey for comparison. We included data from 97366 homeless adults. The pooled prevalence of self-reported hypertension was 27.0% (95% confidence interval=23.8%, 29.9%; n=43 studies) and of diabetes was 8.0% (95% confidence interval=6.8%, 9.2%; n=39 studies). We found no difference in hypertension or diabetes prevalence between the homeless and general population. Additional health care and housing resources are needed to meet the significant, growing burden of chronic disease in the homeless population.

Demand for hospital emergency departments: a conceptual understanding

BACKGROUND

Emergency departments (EDs) are critical to the management of acute illness and injury, and the provision of health system access. However, EDs have become increasingly congested due to increased demand, increased complexity of care and blocked access to ongoing care (access block). Congestion has clinical and organisational implications. This paper aims to describe the factors that appear to influence demand for ED services, and their interrelationships as the basis for further research into the role of private hospital EDs.

DATA SOURCES

Multiple databases (PubMed, ProQuest, Academic Search Elite and Science Direct) and relevant journals were searched using terms related to EDs and emergency health needs. Literature pertaining to emergency department utilisation worldwide was identified, and articles selected for further examination on the basis of their relevance and significance to ED demand.

RESULTS

Factors influencing ED demand can be categorized into those describing the health needs of the patients, those predisposing a patient to seeking help, and those relating to policy factors such as provision of services and insurance status. This paper describes the factors influencing ED presentations, and proposes a novel conceptual map of their interrelationship.

CONCLUSION

This review has explored the factors contributing to the growing demand for ED care, the influence these factors have on ED demand, and their interrelationships depicted in the conceptual model.

Correlates of hospital use in homeless and unstably housed women: the role of physical health and pain

PURPOSE

To examine correlates of emergency department (ED) use and hospitalizations in a community-based cohort of homeless and unstably housed women, with a focus on the role of physical health and pain.

METHODS

We conducted a cross-sectional analysis of baseline survey results from a study of homeless and unstably housed women in San Francisco. Primary outcomes were any self-reported ED visit and inpatient hospitalization over the prior 6 months. Primary independent variables of interest were self-reported physical health status, as measured by the Short Form-12 (SF-12), and bodily pain. Other potential covariates were organized using the Gelberg-Andersen Behavioral Model for Vulnerable Populations. Standard bivariate and multivariable logistic regression techniques were used.

RESULTS

Three hundred homeless and unstably housed women were included in the study, of whom 37.7% reported having an ED visit and 23.0% reported being hospitalized in the prior 6 months. Mean SF-12 physical health scores indicated poorer than average health compared with the U.S. norm. Most women (79.3%) reported at least some limitation in their daily activities owing to pain. In adjusted analyses, moderate and high levels of bodily pain were significantly correlated with ED visits (odds ratio [OR], 2.92 and OR, 2.57) and hospitalizations (OR, 6.13 and OR, 2.49). As SF-12 physical health scores decreased, indicating worse health, the odds of ED use increased. Predisposing, enabling, and additional need factors did not mediate these associations.

CONCLUSIONS

Physical health and bodily pain are important correlates of ED visits and hospitalizations among homeless and unstably housed women. Interventions to reduce ED use among women who are homeless should address the high levels of pain in this population.

An assessment of individual-level factors associated with alcohol treatment utilization among Mexican Americans

The purpose of this study is to identify enabling factors for treatment utilization for alcohol-related problems, and to evaluate how enabling factors vary by need for treatment, among two samples of Mexican American adults. These two distinct samples included 2,595 current and former drinkers (one sample included 787 U.S./Mexico border residents; the other sample included 740 Mexican Americans living in U.S. cities not proximal to the border). Need for treatment (alcohol disorder severity) and (male) gender were the primary correlates of treatment utilization; and there was no moderation in the enabling factors by need for treatment as "enablers" of utilization. Further theoretical and empirical research is necessary to determine which mechanisms are driving disparities in treatment utilization across racial/ethnic groups generally, and Hispanic national groups specifically.

A comprehensive assessment of health care utilization among homeless adults under a system of universal health insurance

OBJECTIVES

We comprehensively assessed health care utilization in a population-based sample of homeless adults and matched controls under a universal health insurance system.

METHODS

We assessed health care utilization by 1165 homeless single men and women and adults in families and their age- and gender-matched low-income controls in Toronto, Ontario, from 2005 to 2009, using repeated-measures general linear models to calculate risk ratios and 95% confidence intervals (CIs).

RESULTS

Homeless participants had mean rates of 9.1 ambulatory care encounters (maximum = 141.1), 2.0 emergency department (ED) encounters (maximum = 104.9), 0.2 medical-surgical hospitalizations (maximum = 14.9), and 0.1 psychiatric hospitalizations per person-year (maximum = 4.8). Rate ratios for homeless participants compared with matched controls were 1.76 (95% CI = 1.58, 1.96) for ambulatory care encounters, 8.48 (95% CI = 6.72, 10.70) for ED encounters, 4.22 (95% CI = 2.99, 5.94) for medical-surgical hospitalizations, and 9.27 (95% CI = 4.42, 19.43) for psychiatric hospitalizations.

CONCLUSIONS

In a universal health insurance system, homeless people had substantially higher rates of ED and hospital use than general population controls; these rates were largely driven by a subset of homeless persons with extremely high-intensity usage of health services.

Predictors of medical or surgical and psychiatric hospitalizations among a population-based cohort of homeless adults

OBJECTIVES

We identified factors associated with inpatient hospitalizations among a population-based cohort of homeless adults in Toronto, Ontario.

METHODS

We recruited participants from shelters and meal programs. We then linked them to administrative databases to capture hospital admissions during the study (2005-2009). We used logistic regression to identify predictors of medical or surgical and psychiatric hospitalizations.

RESULTS

Among 1165 homeless adults, 20% had a medical or surgical hospitalization, and 12% had a psychiatric hospitalization during the study. These individuals had a total of 921 hospitalizations, of which 548 were medical or surgical and 373 were psychiatric. Independent predictors of medical or surgical hospitalization included birth in Canada, having a primary care provider, higher perceived external health locus of control, and lower health status. Independent predictors of psychiatric hospitalization included being a current smoker, having a recent mental health problem, and having a lower perceived internal health locus of control. Being accompanied by a partner or dependent children was protective for hospitalization.

CONCLUSIONS

Health care need was a strong predictor of medical or surgical and psychiatric hospitalizations. Some hospitalizations among homeless adults were potentially avoidable, whereas others represented an unavoidable use of health services.

When health insurance is not a factor: national comparison of homeless and nonhomeless US veterans who use Veterans Affairs Emergency Departments

OBJECTIVES

We examined the proportion of homeless veterans among users of Veterans Affairs (VA) emergency departments (EDs) and compared sociodemographic and clinical characteristics of homeless and nonhomeless VA emergency department users nationally.

METHODS

We used national VA administrative data from fiscal year 2010 for a cross-sectional study comparing homeless (n = 64,091) and nonhomeless (n = 866,621) ED users on sociodemographics, medical and psychiatric diagnoses, and other clinical characteristics.

RESULTS

Homeless veterans had 4 times the odds of using EDs than nonhomeless veterans. Multivariate analyses found few differences between homeless and nonhomeless ED users on the medical conditions examined, but homeless ED users were more likely to have been diagnosed with a drug use disorder (odds ratio [OR] = 4.12; 95% confidence interval [CI] = 3.97, 4.27), alcohol use disorder (OR = 3.67; 95% CI = 3.55, 3.79), or schizophrenia (OR = 3.44; 95% CI = 3.25, 3.64) in the past year.

CONCLUSIONS

In a national integrated health care system with no specific requirements for health insurance, the major differences found between homeless and nonhomeless ED users were high rates of psychiatric and substance abuse diagnoses. EDs may be an important location for specialized homeless outreach (or "in" reach) services to address mental health and addictive disorders.

High utilizers of emergency health services in a population-based cohort of homeless adults

OBJECTIVES

We identified predictors of emergency department (ED) use among a population-based prospective cohort of homeless adults in Toronto, Ontario.

METHODS

We assessed ED visit rates using administrative data from the Institute for Clinical Evaluative Sciences (2005-2009). We then used logistic regression to identify predictors of ED use. Frequent users were defined as participants with rates in the top decile (≥ 4.7 visits per person-year).

RESULTS

Among 1165 homeless adults, 892 (77%) had at least 1 ED visit during the study. The average rate of ED visits was 2.0 visits per person-year, whereas frequent users averaged 12.1 visits per person-year. Frequent users accounted for 10% of the sample but contributed more than 60% of visits. Predictors of frequent use in adjusted analyses included birth in Canada, higher monthly income, lower health status, perceived unmet mental health needs, and perceived external health locus of control from powerful others; being accompanied by a partner or dependent children had a protective effect on frequent use.

CONCLUSIONS

Among homeless adults with universal health insurance, a small subgroup accounted for the majority of visits to emergency services. Frequent use was driven by multiple predisposing, enabling, and need factors.

Navigating the boundaries of emergency department care: addressing the medical and social needs of patients who are homeless

OBJECTIVES

We sought to understand interpersonal and systems-level factors relevant to delivering health care to emergency department (ED) patients who are homeless.

METHODS

We conducted semistructured interviews with emergency medicine residents from 2 residency programs, 1 in New York City and 1 in a medium-sized northeastern city, from February to September 2012. A team of researchers reviewed transcripts independently and coded text segments using a grounded theory approach. They reconciled differences in code interpretations and generated themes inductively. Data collection and analysis occurred iteratively, and interviews continued until theoretical saturation was achieved.

RESULTS

From 23 interviews, 3 key themes emerged: (1) use of pattern recognition in identifying and treating patients who are homeless, (2) variations from standard ED care for patients who are homeless, and (3) tensions in navigating the boundaries of ED social care.

CONCLUSIONS

Our study revealed practical and philosophical tensions in providing social care to patients in the ED who are homeless. Screening for homelessness in the ED and admission practices for patients who are homeless are important areas for future research and intervention with implications for health care costs and patient outcomes.

Homeless in America: injuries treated in US emergency departments, 2007-2011

Despite being a high-risk population, epidemiological research about injuries among homeless individuals is limited. We sought to describe injury characteristics among individuals identified as homeless in the National Electronic Injury Surveillance System (NEISS), and to compare them to age- and sex-matched controls. We searched text narratives for all patients with product-related injuries who presented to NEISS emergency departments from 2007 to 2011 to identify homeless cases (N = 268). A random sample of 2680 age- and sex-matched controls was identified for the same time period. The incident location differed between groups, and the mention of substance use was significantly more common among homeless cases than controls. The body part injured differed significantly between cases and controls for all age groups, with the exception of older adults. Among homeless cases, injuries occurred most frequently to the lower extremities, and sprains/strains, contusions/abrasions and burns were most common. Additional research on injury among homeless individuals is warranted in order to identify meaningful preventive strategies for this at-risk population.

High positive psychiatric screening rates in an urban homeless population

OBJECTIVE

To carry out a preliminary assessment of the use of a psychiatric screening tool in an urban homeless population, and to estimate the potential prevalence of undiagnosed and (or) unmanaged mental illness in this population.

METHODS

Participants (n = 166) were recruited from the Calgary Drop-in and Rehab Centre to complete a questionnaire containing 6 modules screening for common psychiatric disorders. Summary statistics were used in the analysis.

RESULTS

Only 12 respondents (7%) screened negative on each of the 6 modules. The screening process determined that 60.2% of the sample (n = 100) had probable mental illness but reported no history of psychiatric diagnosis or treatment.

CONCLUSIONS

A straightforward application of screening (in which screen-positive subjects are referred for assessment) would be difficult in this population as most will screen positive. The results highlight the tremendous burden of psychiatric symptoms in this population.

Risk factors for ED use among homeless veterans

Despite national concern about homeless veterans, there has been little examination of their use of emergency department (ED) services. This study examines factors related to the use of ED services in the Veterans Affairs (VA) healthcare system, where insurance is not a barrier to ambulatory healthcare. National VA administrative data from fiscal year 2010 are used to describe the proportions of ED users among homeless and domiciled VA patients. A case-control design is then used to compare homeless ED and non-ED users on sociodemographic and clinical correlates, as well as use of ambulatory care and psychotropic medications. Sixteen percent of domiciled VA patients used EDs at least once during the year and 1% were frequent ED users (>4 ED visits) compared to 45% of homeless VA patients, 10% who were frequent ED users. Among homeless VA patients, those who used EDs were more likely to have a range of psychiatric and medical conditions, and had more service visits and psychotropic medication prescriptions than non-ED users. Multivariate analyses suggest their risk for psychiatric and medical conditions increase their likelihood of using ED services. The high rate of ED use among homeless veterans is associated with significant morbidity, but also greater use of ambulatory care and psychotropics suggesting their ED use may reflect unmet psychosocial needs.

A pilot study of the impact of housing first-supported housing for intensive users of medical hospitalization and sobering services

OBJECTIVES

We examined changes in service use in a Housing First (HF) pilot program for adults who were homeless with medical illnesses and high prior acute-care use relative to a similar comparison group.

METHODS

We used a 1-year pre-post comparison group design. The 29 participants and 31 comparison group members were adults who were homeless with inpatient claims of at least $10 000 or at least 60 sobering "sleep off" center contacts in the prior year.

RESULTS

Participants showed a significantly greater reduction in emergency department and sobering center use relative to the comparison group. At a trend level, participants had greater reductions in hospital admissions and jail bookings. Reductions in estimated costs for participants and comparison group members were $62 504 and $25 925 per person per year-a difference of $36 579, far outweighing program costs of $18 600 per person per year.

CONCLUSIONS

HF participants showed striking reductions in acute-care use relative to the comparison group, demonstrating that HF can be a successful model for people with complex medical conditions and high prior acute-care use. Despite notable methodological limitations, these findings could be used to inform a larger multisite study that would establish greater generalizability.

Homelessness and CKD: a cohort study

BACKGROUND AND OBJECTIVES

This study examined the associations between homelessness and clinical outcomes of CKD among adults from the urban healthcare safety net.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

This retrospective cohort study examined 15,343 adults with CKD stages 3-5 who received ambulatory care during 1996-2005 from the Community Health Network of San Francisco. Main outcome measures were time to ESRD or death and frequency of emergency department visits and hospitalizations.

RESULTS

Overall, 858 persons (6%) with CKD stages 3-5 were homeless. Homeless adults were younger, were disproportionately male and uninsured, and suffered from far higher rates of depression and substance abuse compared with adults with stable housing (P<0.001 for all comparisons). Over a median follow-up of 2.8 years (interquartile range=1.4-6.1), homeless adults experienced significantly higher crude risk of ESRD or death (hazard ratio=1.82, 95% confidence interval=1.49-2.22) compared with housed adults. This elevated risk was attenuated but remained significantly higher (adjusted hazard ratio=1.28, 95% confidence interval=1.04-1.58) after controlling for differences in sociodemographics, comorbid conditions, and laboratory variables. Homeless adults were also far more likely to use acute care services (median [interquartile range] number of emergency department visits was 9 [4-20] versus 1 [0-4], P<0.001) than housed counterparts.

CONCLUSIONS

Homeless adults with CKD suffer from increased morbidity and mortality and use costly acute care services far more frequently than peers who are stably housed. These findings warrant additional inquiry into the unmet health needs of the homeless with CKD to provide appropriate and effective care to this disadvantaged group.

Neurobehavioural and cognitive function is linked to childhood trauma in homeless adults

OBJECTIVES

To describe levels of traumatic childhood events in a sample of homeless individuals and to assess the contribution of traumatic events to neurobehavioural traits (measured with the Frontal Systems Behaviour Scale, FrSBe) and general cognitive function (IQ).

DESIGN

A sample of 55 homeless adults was recruited from homeless services in the city of Sheffield, UK. All were interviewed to acquire substance misuse information, record experiences of childhood trauma, and assess cognitive and neurobehavioural traits.

METHODS

Experiences of abuse and neglect were assessed with the Childhood Trauma Questionnaire. Participants also completed the Wechsler Abbreviated Scale of Intelligence and the FrSBe, which was completed with respect to current behaviour and conduct prior to homelessness.

RESULTS

Around three-quarters of the sample scored in the clinically significant range for current neurobehavioural impairment. They also reported high levels of impairment when rating retrospectively for the period before they were homeless. The mean group IQ was below average at 88. Abuse or neglect during their upbringing was reported by 89% of the sample. Emotional abuse, emotional neglect, and physical neglect were all positively correlated with total FrSBe scores. Sexual abuse, emotional neglect, and physical neglect were all negatively correlated with IQ. The associations between trauma and IQ and neurobehavioural traits appear generally unrelated to the presence of substance misuse in the sample.

CONCLUSION

Our homeless sample displayed relatively low IQ with high levels of neurobehavioural impairment. Our evidence suggests that these neuropsychological factors may, in part, constitute a long-term consequence of childhood trauma.

'Meeting people where they're at': experiences of family physicians engaging women who use illicit drugs

PURPOSE

There is little research exploring the experiences of family physicians caring for women who use illicit drugs. This study explores the experiences of these physicians in order to better understand the process of engaging these women in the patient-physician relationship.

METHODS

We conducted a phenomenologic, qualitative study using individual, in-depth interviews with 10 family physicians working in inner-city Toronto and Ottawa, Ontario. An iterative and interpretive analysis was used.

RESULTS

Three broad themes emerged from the analysis. The predominant theme was that of the patient-physician relationship, which consisted of 2 phases: the engagement phase and the maintenance phase. During the engagement phase, issues such as access and women's experiences of trauma and violence were evident and impeded participants' ability to engage with this population. As such, the patient-physician relationship during the engagement phase was tenuous. Trust and presence were paramount during this phase. Once a family physician engaged a woman, the transition to the maintenance phase was made. Within the maintenance phase, 2 subthemes were identified: continuity of care and "meeting people where they're at" (finding common ground).

CONCLUSIONS

This study identified a 2-phase process of the patient-physician relationship from the perspective of family physicians caring for women using illicit drugs: the engagement and maintenance phases. Our findings identified strategies to support the patient-physician relationship during each of these phases that have implications for improving the health of these women.

Deciding to use the emergency room: a qualitative survey of older veterans

Increasing use in the past decade has created pressure for hospital emergency rooms (ERs). Healthcare provided through an ER is expensive and is not designed to meet the complex needs of an older, chronically-ill population. ER visits are presented as the outcome of a decision-making process. Thirty veterans who had visited the ER in the previous year were asked about their decisions to use the ER. Their responses reflected four distinct approaches to ER use, which are characterized by frequency (frequent/infrequent) and risk for social isolation (low/high). Appropriate interventions by social work personnel might reduce inappropriate use of the ER and enhance the care of this vulnerable population.

Health and health care disparities among homeless women

While disparities in health and health care between vulnerable (e.g., minorities, low-income) and majority populations are well documented, less is known about disparities within these special populations that are large and diverse. Such knowledge is essential to determine the neediest within these generally needy populations, and to plan interventions to reduce their health and health care disparities. With data from 1,331 women residing in Los Angeles County California, in one of the largest, most comprehensive studies of the health of homeless women to date, this study examined the health and health care disparities among homeless African American, Latina, and white women. This study further explored if race/ethnicity and other factors that predispose homeless women to poor health, or enable them to obtain better health care, were associated with their unmet need for medical care. The study found that white, non-Latina women were more likely to report unmet need than African Americans and Latinas, and women suffering from drug abuse, violence, or depression were most in need of care. These findings should be considered in targeting and addressing the special needs of homeless women of different racial/ethnic groups.

Patient related factors in frequent readmissions: the influence of condition, access to services and patient choice

Background

People use emergency department services for a wide variety of health complaints, many of which could be handled outside hospitals. Many frequent readmissions are due to problems with chronic disease and are preventable. We postulated that patient related factors such as the type of condition, demographic factors, access to alternative services outside hospitals and patient preference for hospital or non-hospital services would influence readmissions for chronic disease. This study aimed to explore the link between frequent readmissions in chronic disease and these patient related factors.

Methods

A retrospective analysis was performed on emergency department data collected from a regional hospital in NSW Australia in 2008. Frequently readmitted patients were defined as those with three or more admissions in a year. Clinical, service usage and demographic patient characteristics were examined for their influence on readmissions using multivariate analysis.

Results

The emergency department received about 20,000 presentations a year involving some 16,000 patients. Most patients (80%) presented only once. In 2008 one hundred and forty four patients were readmitted three or more times in a year. About 20% of all presentations resulted in an admission. Frequently readmitted patients were more likely to be older, have an urgent Triage classification, present with an unplanned returned visit and have a diagnosis of neurosis, chronic obstructive pulmonary disease, dyspnoea or chronic heart failure. The chronic ambulatory care sensitive conditions were strongly associated with frequent readmissions. Frequent readmissions were unrelated to gender, time, day or season of presentation or country of birth.

Conclusions

Multivariate analysis of routinely collected hospital data identified that the factors associated with frequent readmission include the type of condition, urgency, unplanned return visit and age. Interventions to improve patient uptake of chronic disease management services and improving the availability of alternative non-hospital services should reduce the readmission rate in chronic disease patients.

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.

The value of the presence of social work in emergency departments

The value of the presence of social work in emergency rooms is supported by directly examining the hospitalization rates of patients seen by social workers. It utilizes a 3-year-long data set of social work self-reports on medical emergency room outcomes at a large, teaching hospital in the New York Metropolitan area with a sample size of 3370. The study findings suggest that social workers in this acute care hospital's emergency room often are referred the most complex cases. The data on this site indicate that the majority of social work dispositions were to home (54%) or a nursing facility (8.4%). Only 16% of the patients seen by social work were admitted to the hospital. These findings support the cost-effective nature of social work in the emergency room setting and the importance of finding alternatives to hospital admissions. The results of a logistic regression suggest that the criteria used by social workers to assess patients are based on sound psychosocial factors. Patients who were assessed as having "Environmental" (p = .00) or "Relationship" problems (p = .00) were much less likely to be admitted. Conversely, patients with "Care/ADL" problems (p = .00) and behavior problems (p = .00) had a heightened chance of being admitted. Being African American has less effect but was still relevant.

Physical diseases among homeless people: gender differences and comparisons with the general population

AIM

To study morbidity amongst homeless men and women by comparing prevalence of hospital care for somatic diseases and injuries with a control group of men and women from the general population.

METHODS

A cohort of 1,364 men and 340 women were documented as homeless in 1996. Comparisons are made concerning hospital care for somatic diseases and injuries (1996-2002) among 3,750 men and 1,250 women from the general population.

RESULTS

The relative risk (RR) for homeless men and women of being hospitalised was double that of the men and women in the controls (1.93 and 1.96 respectively). Homeless women had a slightly, not significant, increased risk compared to homeless men (RR 1.10). Younger homeless women had a significant higher risk. Among diagnostic categories, the highest prevalence was found among homeless men in the diagnosis group injury/poisoning (22%). The highest risk was found for skin diseases (RR 36.96) and concerned homeless women. There were a number of gender specific diagnoses, where risks were considerably elevated, such as diseases of the genital organs, viral hepatitis, and poisoning for homeless women, and cerebrovascular diseases, diseases of the liver, and concussion for homeless men.

CONCLUSIONS

Homeless people had twice the risk of being hospitalised for physical diseases compared to the general population. Younger women were particularly at risk compared to homeless men and to women in the controls. There were a number of gender specific diagnoses that are important to take into account when planning services for homeless people.

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.
