Enhancing administrative data to predict emergency department utilization: the role of neighborhood sociodemographics.
Much of emergency department (ED) use is avoidable, and high-quality primary care can reduce it, but performance measures related to ED use may be inadequately risk-adjusted. To explore associations between ED use and neighborhood poverty, a secondary analysis of Massachusetts managed care network data, 2009-2011, was conducted.

Accuracy of self-reported health care use in a population-based sample of homeless adults.
The objective of this study was 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.It found that adults experiencing homelessness are quite accurate reporters of their use of health care, especially for ED encounters and hospitalizations.

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.

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.
