Organizational Factors Associated With Technical Efficiency of Nursing Care in US Intensive Care Units

초록

Background: Few studies have evaluated technical efficiency of nursing care, and no such studies have been conducted in intensive care units (ICUs). Purpose: To explore relative technical efficiency of US ICUs and identify organizational factors associated with efficiency in providing quality of nursing care. Methods: A total of 404 adult ICUs from the 2014 National Database of Nursing Quality Indicators were included. Data envelopment analysis was used to estimate technical efficiency, and multilevel modeling was employed to determine effects of organizational factors on efficiency. Results: Nurse-to-patient ratio showed the strongest positive correlation with technical efficiency. Units in non-Magnet and small-size hospitals had higher technical efficiency than those in Magnet and medium- or large-size hospitals. Conclusions: A higher nurse-to-patient ratio greatly improved technical efficiency of nursing care in ICUs and the effect differed between hospitals. Administrators and policy makers can translate the study findings into management strategies to provide efficient nursing care in ICUs.
