Background: Nurse staffing levels are an important working condition issue for nurses and believed to be a determinant of the quality of nursing care and patient outcomes. Objectives:To examine the effects of nurse staffing on adverse events, morbidity, mortality, and medical costs. Methods:Using two existing databases, the study sample included 232 acute care California hospitals and 124,204 patients in 20 surgical diagnosis-related groups. The adverse events included patient fall/injury, pressure ulcer, adverse drug event, pneumonia, urinary tract infection, wound infection, and sepsis. Multilevel analysis was employed to examine, simultaneously, the effects of nurse staffing and patient and hospital characteristics on patient outcomes.Results: Three statistically significant relationships were found between nurse staffing and adverse events. An increase of 1 hour worked by registered nurses (RN) per patient day was associated with an 8.9% decrease in the odds of pneumonia. Similarly, a 10% increase in RN Proportion was associated with a 9.5% decrease in the odds of pneumonia. Providing a greater number of nursing hours per patient day was associated with a higher probability of pressure ulcers. The occurrence of each adverse event was associated with a significantly prolonged length of stay and increased medical costs. Patients who had pneumonia, wound infection or sepsis had a greater probability of death during hospitalization. Conclusion:Patients are experiencing adverse events during hospitalization. Care systems to reduce adverse events and their consequences are needed. Having appropriate nurse staffing is a significant consideration in some cases.

The purpose of this study was to ascertain the interest by executives of major corporations in having occupational health nurses engage in more advanced activities, and to ascertain the available support for advanced educational preparation for nurses. A questionnaire was sent to a systematic sample of 404 of the 808 executives of the Forbes 500 corporations with a 57% return rate. Over 90% of the corporations with health care departments employed registered nurses. Functions nurses currently performed varied by size of the corporation and by type of industry. Activities corporations would like nurses to perform were more advanced, such as conducting research, analyzing trends, and developing special health programs.
