Left Without Being Seen: Nurse Work Environment and Timely Outcomes in New York and Illinois Emergency Departments.

INTRODUCTION:This study determined the relationship between the emergency nurse work environment and emergency department patient left without being seen rates and lengths of stay. METHODS:Cross-sectional analysis of 215 New York and Illinois emergency departments. The work environment (abbreviated Practice Environment Scale of the Nursing Work Index) was measured by emergency nurses in the 2021 RN4CAST-NY/IL survey and linked with outcomes from Hospital Compare. Regression models estimated the relationship between the nurse work environment and emergency department patient left without being seen rates, median length of stay (in minutes), and median behavioral health patient length of stay. Model coefficients were used to estimate expected additional care minutes gained if emergency department work environments improved. RESULTS:"Mixed" work environments had the longest median overall length of stay (3.4 hours) and the highest median left without being seen rates (2.2%), while "poor" work environments had the longest median length of stay for behavioral health patients (6 hours). Improving the emergency department work environment from poor to mixed (and mixed to better) was associated with a 13-minute reduction in overall length of stay (P ≤ .05), a 33-minute reduction in behavioral health length of stay (P ≤ .01), and a 19% reduction in left without being seen rates (P ≤ .01). We estimated 11,824 to 41,071 additional patients could be seen in emergency departments associated with work environment improvements from "poor" to "better," depending on annual patient volumes. DISCUSSION:Hospital administrators should consider investing in nurse work environments as a foundation to improve timely outcomes.
