Background: One out of every 5 Americans live in rural communities. Rural Americans have higher rates of early and preventable deaths outside of the hospital than their urban counterparts. How rurality relates to hospital mortality is unknown. We sought to determine the association between rural versus urban residence and hospital mortality.Methods: This is a retrospective observational study of 4,412,942 nonmaternal, nonneonatal hospitalizations in 2008, and 3899,464 nonmaternal, nonneonatal hospitalizations in 2013 using all-payer, all-age data from the National Inpatient Sample of the Health care Cost and Utilization Project. Using multivariable logistic regression, we report the association between rural versus urban location of residence and hospital mortality, adjusting for chronic disease burden, age, income, and insurance status.Results: The unadjusted probability of hospital mortality for urban patients decreased from 2.51% (95% CI ,
