Perioperative nurses and patient outcomes: mortality, complications, and length of stay.

The purpose of the study described in this article was to identify the relationship between RN staffing factors in the OR and surgical patient outcomes. The study addressed two main questions: whether the level of RN staffing in the OR is related to postoperative complications, mortality, and length of stay (LOS) and whether certification, RN agency use, 24-hour staffing, and the performance of multi-disciplinary code drills are related to complication mortality, and LOS. According to this study, selected organizational factors in ORs had a significant influence on patient outcomes.
