Effects of Emergency Nurses' Life-Sustaining Treatment Withdrawal Knowledge, Role Perception, and Job Stress on...

This study aimed to identify predictors of end-of-life (EOL) care provided by emergency nurses in South Korea.

A cross-sectional survey was conducted using a structured questionnaire. Data were collected using Google Forms between June 21 and 30, 2022. A total of 154 emergency nurses from 10 tertiary hospitals in a metropolitan area were recruited using convenience sampling, and 139 completed surveys were analyzed. Multiple linear regression was employed to examine the effects of nurses' knowledge of life-sustaining treatment withdrawal (knowledge), their perceptions of their role in the withdrawal process (role perception), and job stress on EOL care.

The mean scores for knowledge, role perception, job stress, and EOL care were 13.09±1.75 (max 6), 4.18±0.44 (max 5), 3.55±0.32 (max 4), and 2.48±0.40 (max 4), respectively. Among the EOL care subdomains, psychological domain scores were the highest. Multiple linear regression analysis indicated that nurses' role perception significantly predicted EOL care performance, particularly in the psychological (F=3.924, P=0.001) and spiritual (F=2.171, P=0.020) domains.

Despite the challenging environment of the emergency department, nurses who recognize their important role in the process of life-sustaining treatment withdrawal are more likely to provide high-quality EOL care. The perception of nurses' roles is especially influential on psychological care performance, and alternative approaches may be necessary for spiritual care.
