Single women who are homeless visit a hospital Emergency Department an average of more than twice a year, 13 times more often than women in the general population, new research has found.
Single men who are homeless make an average of two visits a year to emergency, nine times more than men in the general population.
Homeless men, women and families also have significantly more doctors' appointments and higher hospitalization rates, according to research led by Dr. Stephen Hwang of the Centre for Research on Inner City Health at St. Michael's Hospital in Toronto. A small subset of homeless people are extremely frequent users of health services.
Dr. Hwang's findings were published today in three papers in a special issue of the American Journal of Public Health devoted to homelessness and public health, one looking at the overall health care use by homeless people and two others examining factors that can predict frequent ED use or hospitalizations. All three papers used data from the Institute for Clinical Evaluative Sciences, where Dr. Hwang is an adjunct scientist.
Dr. Hwang said that while homeless people are known to have higher rates of chronic and acute health conditions than the general population, no comprehensive assessment of their health care use has been done previously. This information is difficult to obtain in the United States, where more than half of homeless adults lack health insurance, and previous studies were based on single health care institutions or homeless people self-reporting their health care use.
His study is unique because it followed 1,165 people over four years on average in Toronto, where there is universal, government-funded health insurance, and comprehensive databases that capture all doctors, ED and hospital visits. The homeless people, recruited from shelters and meal programs, were compared with low-income people in the general population of the same age and gender.
He said his study has important policy implications for the delivery of health services, especially given recent legislative changes that expanded Medicaid coverage to low-income Americans. Traditionally, a lack of health insurance has been identified as a significant barrier to obtaining ambulatory care in the United States, resulting in unnecessary ED visits and avoidable hospitalizations.
"However, as our findings demonstrate, homeless individuals within a system of universal health insurance continue to have much higher rates of ED and inpatient hospital use compared to the general population," he said. "The provision of universal health insurance, while important, doesn't fully address the barriers to appropriate health care for this vulnerable population. We also need to improve the management of chronic physical and mental illness, and address structural factors such as a lack of affordable housing."
