The Revised Nursing Work Index (NWI-R) is a widely used instrument for evaluating registered nurses' (RNs) practice environments. The existence of multiple subscale sets from the NWI-R raises questions about its generalizability. We tested the validity of the one-, three-, and five-subscale sets from the NWI-R and derived a short-form subscale set using a sample of RNs from the Veterans Health Administration (VHA). The prior sets do not have an excellent fit to these data. Results of exploratory factor analyses suggested a four-factor model with Opportunity for Advancement, Collegial Nurse-Physician Relations, Staffing Adequacy, and Nurse Manager Leadership as the most salient and parsimonious solution.

Our findings suggest that the association between RN staffing and skill mix and in-hospital patient mortality depends on whether the analysis is conducted at the hospital or unit level. Variable staffing on non-ICU units may significantly contribute to in-hospital mortality risk.

Background: Severe mental illness (SMI) has been associated with more medical co-morbidity and less cardiovascular procedure use for older patients with myocardial infarction. However, it is unknown whether SMI is associated with increased long term mortality risk among patients presenting with acute coronary syndromes (ACS). We tested the hypothesis that SMI is associated with higher one-year mortality following ACS hospitalization.

The nursing work force of the VHA has some unique characteristics. The practice environment for nurses in the VHA is relatively positive, and may indicate that the VHA, as a system, provides an environment that is more like magnet hospitals. This is significant for a public sector hospital system.
