A comprehensive assessment of health care utilization among homeless adults under a system of universal health insurance.
The researchers comprehensively assessed health care utilization in a population-based sample of homeless adults and matched controls under a universal health insurance system. They found that 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.

Health information exchange improves identification of frequent emergency department users.
The goal of the project was to measure the incremental increase in the number of frequent ED users who were identified when data
from all EDs participating in an health information exchange were compared with site-specific data. When the researchers analyzed HIE-wide data instead of site-specific data, they identified 20.3 percent more frequent ED users and 16.0 percent more visits by them to the ED.

High utilizers of emergency health services in a population-based cohort of homeless adults.
This study identified predictors of frequent emergency department (ED) use among a population-based sample of homeless adults in Toronto, Ontario. It found that 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.
