The clinical and economic impact of nurse to patient staffing ratios in women receiving intrapartum oxytocin.

Objective: To examine the relationship between nurse-to-patient staffing ratios and perinatal outcomes in women receiving oxytocin during labor.
Study Design: A retrospective analysis of perinatal outcomes in women receiving oxytocin for induction or augmentation of labor during 2010. Outcomes examined were fetal distress, birth asphyxia, primary cesarean delivery, chorioamnionitis, endomyometritis, and a composite of adverse events. Frequency of 1:1 nurse-to-patient staffing was determined for each hospital. Outcomes were compared between hospitals categorized into quartiles of staffing ratios.
Results: In 208,033 women delivering during 2010, there was no relation between frequency of 1:1 nurse-to-patient staffing ratio and improved perinatal outcomes. Adoption of universal 1:1 staffing in the United States would result in the need for an additional 27,000 labor nurses and a cost of $1.6 billion.
Conclusion: Available data do not support the imposition of mandatory 1:1 nurse-to-patient staffing ratios for women receiving oxytocin in all U.S. facilities.
