BACKGROUND: Patients experiencing homelessness represent a disproportionate share of emergency department (ED) visits due to poor access to primary care and high levels of unmet health care needs. This is in part due to the difficulty of communicating and following up with patients who are experiencing homelessness. OBJECTIVE: To determine the prevalence and types of "new media" use among ED patients who experience homelessness. METHODS: This was a cross-sectional observational study with sequential enrolling of patients from three emergency departments 24/7 for 6 weeks. In total, 5788 ED patients were enrolled, of whom 249 experienced homelessness. Analyses included descriptive statistics, and unadjusted and adjusted odds ratios. RESULTS: 70.7% (176/249) of patients experiencing homelessness own cell phones compared to 85.90% (4758/5539) of patients in stable housing (P=.001) with the former more likely to own Androids, 70% (53/76) versus 43.89% (1064/2424), and the latter more likely to have iPhones, 44.55% (1080/2424) versus 17% (13/76) (P=.001). There is no significant difference in new media use, modality, or frequency for both groups; however, there is a difference in contract plan with 50.02% (2380/4758) of stably housed patients having unlimited minutes versus 37.5% (66/176) of homeless patients. 19.78% (941/4758) of patients in stable housing have pay-as-you-go plans versus 33.0% (58/176) of homeless patients (P=.001). Patients experiencing homelessness are more likely to want health information on alcohol/substance abuse, mental health, domestic violence, pregnancy and smoking cessation. CONCLUSIONS: This study is unique in its characterization of new media ownership and use among ED patients experiencing homelessness. New media is a powerful tool to connect patients experiencing homelessness to health care.

BACKGROUND: National attention is increasingly focused on hospital readmissions. Little prior research has examined readmissions among patients who are homeless. OBJECTIVE: The aim of the study was to determine 30-day hospital readmission rates among patients who are homeless and examine factors associated with hospital readmissions in this population. METHODS: We conducted a retrospective chart review of patients who were homeless and hospitalized at a single urban hospital from May-August 2012. Homelessness was identified by an electronic medical record flag and confirmed by manual chart review. The primary outcome was all-cause hospital readmission to the study hospital within 30 days of hospital discharge. Patient-level and hospitalization-level factors associated with risk for readmission were examined using generalized estimating equations. RESULTS: There were 113 unique patients who were homeless and admitted to the hospital a total of 266 times during the study period. The mean age was 49 years, 27.4% of patients were women, and 75.2% had Medicaid. Half (50.8%) of all hospitalizations resulted in a 30-day hospital inpatient readmission and 70.3% resulted in either an inpatient readmission, observation status stay, or emergency department visit within 30 days of hospital discharge. Most readmissions occurred early after hospital discharge (53.9% within 1 week, 74.8% within 2 weeks). Discharge to the streets or shelter versus other living situations was associated with increased risk for readmission in multivariable analyses. CONCLUSIONS: Patients who were homeless had strikingly high 30-day hospital readmission rates. These findings suggest the urgent need for further research and interventions to improve postdischarge care for patients who are homeless.

STUDY OBJECTIVE: There is widespread concern about patients with frequent emergency department (ED) use. We identify sociodemographic and clinical factors most strongly associated with frequent ED use within the Veterans Health Administration (VHA) nationally. METHODS: We conducted a cross-sectional analysis of national VHA databases (N=5,531,379) in 2010. The primary outcome measure was the number of VHA ED visits categorized into 6 frequency levels. RESULTS: In 2010, 4,600,667 (83.2%) VHA patients had no ED visit, whereas 493,391 (8.9%) had 1 visit, 356,258 (6.4%) had 2 to 4 visits, 70,741 (1.3%) had 5 to 10 visits, 9,705 (0.2%) had 11 to 25 visits, and 617 (0.01%) had greater than 25 visits. Increasing ED use frequency was associated with homelessness, medical diagnoses, substance abuse and psychiatric diagnoses, receipt of psychotropic and opioid prescriptions, and more frequent use of outpatient medical and mental health services. In multivariable analyses, factors most strongly associated with all levels of ED use were schizophrenia (odds ratio [OR] range 1.44 [95% confidence interval {CI} 1.41 to 1.47] to 6.86 [95% CI 5.55 to 8.48] across categories of increasing ED use), homelessness (OR range 1.41 [95% CI 1.38 to 1.43] to 6.60 [95% CI 5.36 to 8.12]), opioid prescriptions filled (OR range 2.09 [95% CI 2.07 to 2.10] to 5.08 [95% CI 4.16 to 6.19]), and heart failure (OR range 1.64 [95% CI 1.63 to 1.66] to 3.53 [95% CI 2.64 to 4.72]). CONCLUSION: Frequent ED use occurs even in a coordinated health care system that provides ready access to outpatient care. Frequent ED users are characterized by traits that represent high levels of psychosocial and medical needs. The correlates we identified for frequent ED use were consistent across multiple distinct levels of ED use.

Background: Homeless patients visit the ED at rates up to 12 times higher than comparable housed patients, yet there is a paucity of research on how this influences emergency medicine residents, who are the primary physician caregivers in many EDs. Objectives: To characterize the experiences of EM residents in caring for homeless patients and explore how these experiences influence resident personal and professional development. Methods: We conducted in-depth interviews with residents of two northeast urban EM residency programs. A random purposeful sample diverse in training year was selected, with sample size determined by theoretical saturation. Interviews were digitally recorded and professionally transcribed. A core team of three researchers with diverse content-relevant expertise independently coded transcripts and met regularly to reconcile coding differences. The constant comparison method was used to identify new codes and refine existing ones iteratively. The final code structure was applied to all data using Atlas.ti (GmbH). Results: Four core themes pertaining to the resident experience emerged from 23 interviews. First, residents learn how to care for homeless patients through modeling more senior physicians, storytelling, and experience, rather than formal curricular training. Second, residents learn unique aspects of EM by caring for homeless patients. For example, residents learn to integrate social and systems-level factors into medical decision making (i.e., considering homelessness in disposition decisions). Third, residents struggle with role boundaries as emergency physicians when caring for homeless patients. Though the ED regularly fills gaps in the social service system by providing shelter, food, and other non-medical resources, residents vary in how much of this care they embrace as their job. Finally, caring for homeless patients affects residents emotionally. While residents feel pride in EM's mission to serve all patients, they feel frustrated by what they perceive !

Medical respite programs provide care to homeless patients who are too sick to be on the streets or in a traditional shelter, but not sick enough to warrant inpatient hospitalization. They are designed to improve the health of homeless patients while also decreasing costly hospital use. Although there is increasing interest in implementing respite programs, there has been no prior systematic review of their effectiveness. We conducted a comprehensive search for studies of medical respite program outcomes in multiple biomedical and sociological databases, and the grey literature. Thirteen articles met inclusion criteria. The articles were heterogeneous in methods, study quality, inclusion of a comparison group, and outcomes examined. Available evidence showed that medical respite programs reduced future hospital admissions, inpatient days, and hospital readmissions. They also resulted in improved housing outcomes. Results for emergency department use and costs were mixed but promising. Future research utilizing adequate comparison groups is needed.

STUDY OBJECTIVE: Our objective is to determine whether a point-of-care intervention that navigates willing, low-acuity patients from the emergency department (ED) to a Primary Care Clinic will increase future primary care follow-up. METHODS: We conducted a quasi-experimental trial at an urban safety net hospital. Adults presenting to the ED for select low-acuity problems were eligible. Patients were excluded if arriving by emergency medical services, if febrile, or if the triage nurse believed they required ED care. We enrolled 965 patients. Navigators escorted a subset of willing participants to the Primary Care Clinic (in the same hospital complex), where they were assigned a personal physician, were given an overview of clinic services, and received same-day clinic care. The primary outcome was Primary Care Clinic follow-up within 1 year of the index ED visit among patients having no previous primary care provider. RESULTS: In the bivariate intention-to-treat analysis, 50.3% of intervention group patients versus 36.9% of control group patients with no previous primary care provider had at least 1 Primary Care Clinic follow-up visit in the year after the intervention. In the multivariable analysis, the absolute difference in having at least 1 Primary Care Clinic follow-up for the intervention group compared with the control group was 9.3% (95% confidence interval 2.2% to 16.3%). There was no significant difference in the number of future ED visits. CONCLUSION: A point-of-care intervention offering low-acuity ED patients the opportunity to alternatively be treated at the hospital's Primary Care Clinic resulted in increased future primary care follow-up compared with standard ED referral practices.

ABSTRACT: BACKGROUND: A small percentage of high-risk patients accounts for a large proportion of Medicaid spending in the United States, which has become an urgent policy issue. Our objective was to pilot a novel patient-centered intervention for high-risk patients with frequent hospital admissions to determine its potential to improve care and reduce costs. METHODS: Community and hospital-based care management and coordination intervention with pre-post analysis of health care utilization. We enrolled Medicaid fee-for-service patients aged 18-64 who were admitted to an urban public hospital and identified as being at high risk for hospital readmission by a validated predictive algorithm. Enrolled patients were evaluated using qualitative and quantitative interview techniques to identify needs such as transportation to/advocacy during medical appointments, mental health/substance use treatment, and home visits. A community housing partner initiated housing applications in-hospital for homeless patients. Care managers facilitated appropriate discharge plans then worked closely with patients in the community using a harm reduction approach. RESULTS: Nineteen patients were enrolled; all were male, 18/19 were substance users, and 17/19 were homeless. Patients had a total of 64 inpatient admissions in the 12 months before the intervention, versus 40 in the following 12 months, a 37.5% reduction. Most patients (73.3%) had fewer inpatient admissions in the year after the intervention compared to the prior year. Overall ED visits also decreased after study enrollment, while outpatient clinic visits increased. Yearly study hospital Medicaid reimbursements fell an average of $16,383 per patient. CONCLUSIONS: A pilot intervention for high-cost patients shows promising results for health services usage. We are currently expanding our model to serve more patients at additional hospitals to see if the pilot's success can be replicated. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT01292096

OBJECTIVE: To explore medical students' perceptions of their future role as physicians as it relates to personal and professional responsibilities toward the underserved. METHODS: The authors conducted a qualitative content analysis of 53 first-year medical students' reflective essays focusing on the question: "Access to health care is a societal problem. Do physicians have a professional obligation to help by participating in free clinics, or otherwise doing some service-type activity? What are your personal feelings about how you might balance service to other people with personal issues like income, family, and career choice?" RESULTS: The student essays revealed students' awareness of the distinct expertise that enables physicians to offset limited access to health care. Although the majority of respondents supported physicians' responsibility to provide uncompensated care, a minority believed that there was no such responsibility attached to being a physician. Students also recognized the competing demands physicians often encounter that conflict with personal desires for service. CONCLUSION: The use of reflective essays in medical school curricula seems promising, in that they elicited students' beliefs on a complex topic with direct implications for professional identity and career decisions.
