Odds ratios compare surgical mortality for hospitals with a high proportion of non-US-educated nurses (>25%) to all other hospitals in the sample. All regressions were adjusted for nurse (practice environment, percent with BSN education, proportion of nurses in ICU and proportion of nurses in medical-surgical unit) and hospital characteristics (bed size, teaching status and technology status) and dummy variables for state.
