Missed nursing care is a key indicator of patient safety and has been linked to safety climate. Survey responses from 3,429 labor and delivery nurses from 253 hospitals across the United States found an average of 11 of 25 aspects of essential nursing care were occasionally, frequently, or always missed. Higher perceived safety climate was associated with less missed care. The authors discuss the importance of strategies to reduce missed care, such as adequate nurse staffing, ensuring nonpunitive responses to errors, and promoting open communication.
