Table 4.

Partly and fully adjusted odds ratios showing the effects of nurse staffing and nurse education on 30 day inpatient mortality

Partly adjusted models Fully adjusted model
OR (95% CI) p value OR (95% CI) p value
Staffing 1·005 (0·965–1·046) 0·816 1·068 (1·031–1·106) 0·0002
Education 1·000 (0·959–1·044) 0·990 0·929 (0·886–0·973) 0·002

The partly adjusted models estimate the effects of nurse staffing and nurse education separately while controlling for unmeasured differences across countries. The fully adjusted model estimates the effects of nurse staffing and nurse education simultaneously, controlling for unmeasured differences across countries and for the hospital characteristics (bed size, teaching status, technology, and work environment), and patient characteristics (age, sex, admission type, type of surgery, and comorbidities present on admission). OR=odds ratio.
