# The intersection of Physical Disability and Homelessness: A Community-Engaged Research Initiative

## TL;DR

This study examines how homelessness and physical disability intersect, showing that homeless individuals with disabilities face worse healthcare outcomes than housed individuals.

## Contribution

The study introduces a community-engaged research model to analyze healthcare outcomes among homeless individuals with physical disabilities.

## Key findings

- Homeless individuals with physical disabilities had higher 30-day readmission rates after traumatic brain injury compared to housed individuals.
- The study identified 746 homeless individuals with physical disabilities out of 16,024 participants.
- Collaboration with the homeless community helped prioritize outcomes like shelter use duration and readmission rates.

## Abstract

People experiencing homelessness (PEH), compared to their housed peers, experience higher rates of chronic conditions and accelerated disease progression, which can result in a physical disability (e.g., stroke). This project co-designed and executed an examination of homelessness and healthcare service use and outcomes of PEH with a physical disability compared to their peers. This project was a collaboration between the PEH community and academic researchers, which was guided by a co-created shared governance structure and the 10-Step Framework for Continuous Community Engagement. Collaborative prioritization efforts identified outcomes of interest (e.g., duration of homeless shelter use, 30-day readmissions). To examine homelessness service use among PEH, we leveraged Medicaid claims to identify those who had an index stroke, traumatic brain injury (TBI), or amputation as a surrogate for physical disability and linked to the Homelessness Management Information Systems. To examine healthcare utilization and outcomes we used electronic medical records (EMR) to create a cohort of patients with an index physical disability, stratified by housing status (i.e., PEH vs. housed). The PEH cohort (n = 16,024) included those with an index homeless service event between July 2015 and June 2023, of which 5% (n = 746) had a physical disability. Our one-year EMR cohort included patients experiencing an index physical disability—stroke (n = 9,547), TBI (n = 6,708), or amputation (n = 3,494). PEH had more 30-day readmissions (e.g., 46% vs. 32%, P value=0.01, after TBI) than their housed peers. This collaboration highlights the importance of community partnerships to identify populations to target in future quality initiatives.
