Regression coefficients indicating the effects of staffing and practice environment on average number of types of care missed

  • Adjusted coefficients and CIs are from regression models which control for hospital characteristics (beds >750, high technology and location) and nurse characteristics (nurse role, full-time status, years of experience and unit type). Practice environment is measured by the Practice Environment Scale of the Nursing Work Index tertile.

  • Source: Data are from the 2010 RN4CAST-England study, which surveyed 2963 inpatient medical and surgical direct care professional nurses (RNs) in a representative sample of 31 National Health Service trusts comprising 46 different hospitals.
