Prior research suggests that improved nursing resources may be associated with decreased mortality and adverse events. However, less is known about how changes to nursing resources in the inpatient setting may affect quality and safety over time. In this study involving 737 hospitals and survey data from nurses obtained in 2006 and 2016, researchers found that after adjusting for numerous factors, better nursing resources in terms of work environment, staffing, and education was associated with improvement in quality and patient safety outcomes. A PSNet perspective discussed the impact of nursing resources on patient safety.
