Commentary: How Can Emergency Departments Help End Homelessness? A Challenge to Social Emergency Medicine

Optimising Access to Healthcare for Patients Experiencing Homelessness in Hospital Emergency Departments

The ED is often the first and sometimes the only place where people experiencing homelessness seek medical assistance. While access to primary healthcare is a preferable and more cost-effective alternative to ED, for many reasons, people experiencing homelessness are much less likely to have a regular General Practitioner compared to those living in stable accommodation. Drawing on a growing body of emergency care and homelessness literature and practice, we have synthesised four potential interventions to optimise access to care when people experiencing homelessness present to an ED. Although EDs are in no way responsible for resolving the complex health and social issues of their local homeless population, they are a common contact point and therefore present an opportunity to improve access to healthcare.

Multistage Psychometric Testing of the Homeless Health Access to Care Tool

People experiencing homelessness find it challenging to access the healthcare they so desperately need. To address this, we have developed the Homeless Health Access to Care Tool, which assesses health related vulnerability (burden of injury and/or illness and ability to access healthcare) and can be used to prioritize people for access to healthcare. Here, we report the initial psychometrics of the Homeless Health Access to Care Tool. To assess interrater reliability, clinician participants were invited to instinctually rate the health-related vulnerability of 18-fictional case studies and then apply the Homeless Health Access to Care Tool to these same case studies. To assess convergent validity, the Homeless Health Access to Care Tool and the tool it was adapted from, the Australian Vulnerability Index Service Prioritization Decision Assistance Tool were administered to people experiencing homelessness. Feedback was sought from the participants receiving these two tools and from those administering them. The Homeless Health Access to Care Tool demonstrated a high interrater reliability and internal consistency. Participants using and receiving the Homeless Health Access to Care Tool reported it as straightforward, unintrusive and clear. Median time of administration was 7 min 29 s (SD 118.03 s). Convergent validity was established for the Homeless Health Access to Care Tool with a moderate correlation (r = 0.567) with the total score of the Australian Vulnerability Index Service Prioritization Decision Assistance Tool. Findings suggest that the Homeless Health Access to Care Tool is feasible and reliable. Larger samples are required to report construct validity.

Homeless Shelter Entry in the Year After an Emergency Department Visit: Results From a Linked Data Analysis

STUDY OBJECTIVE

Housing instability is prevalent among emergency department (ED) patients and is known to adversely affect health. We aim to determine the incidence and timing of homeless shelter entry after an ED visit among patients who are not currently homeless.

METHODS

We conducted a random-sample survey of ED patients at an urban public hospital from November 2016 to September 2017. Patients provided identifying information and gave informed consent for us to link their survey data with the New York City Department of Homeless Services shelter database. Shelter use was followed prospectively for 12 months after the baseline ED visit. We examined timing of shelter entry in the 12 months after the ED visit, excluding patients who were homeless at baseline.

RESULTS

Of 1,929 unique study participants who were not currently homeless, 96 (5.0%) entered a shelter within 12 months of their baseline ED visit. Much of the shelter entry occurred in the first month after the ED visit, with continued yet slower rates of entry in subsequent months. Patients in our sample who entered a shelter were predominantly men and non-Hispanic black, and commonly had past shelter and frequent ED use.

CONCLUSION

In this single-center study, 5.0% of urban ED patients who were not currently homeless entered a homeless shelter within the year after their ED visit. Particularly if replicated elsewhere, this finding suggests that ED patients may benefit from efforts to identify housing instability and direct them to homelessness prevention programs.
