Experiences of nurses working as physician assistants under the expanded scope-of-practice policy following the 2024 resignation of medical residents in South Korea: a phenomenological study: Tae Yeong Yang, Myung Jin Jang, NaHyun Lee; J Korean Acad Nurs 2026;56(2):220-232.

Abstract PDF ePub: Purpose
This study aimed to explore the lived experiences of clinical support nurses under the expanded scope-of-practice policy implemented after the mass resignation of medical residents in Korea in 2024. In Korea, these nurses are often referred to as physician assistant (PA) nurses, although they differ from licensed physician assistants or nurse practitioners in the United States. The study sought to understand how the policy was perceived, implemented, and interpreted by nurses who played a key role in maintaining clinical services during a healthcare workforce crisis.
Methods
A qualitative phenomenological design based on Colaizzi’s method was used. Fourteen clinical support nurses from a tertiary hospital in Seoul participated in in-depth, semi-structured interviews conducted between August and December 2025. The interviews were transcribed verbatim and analyzed through iterative reading, extraction of significant statements, formulation of meanings, and thematic integration. Trustworthiness was established using the criteria of credibility, dependability, transferability, and confirmability.
Results
Four essential themes were identified: (1) multifaceted perceptions of the 98-item expanded scope-of-practice policy; (2) gaps in the current education system and demands for structured training; (3) ambivalent experiences during policy implementation; and (4) conditional acceptance of the policy’s sustainability and calls for improvement. Participants reported increased professional recognition and autonomy while also experiencing ambiguity in role boundaries, concerns about legal accountability, and emotional burden related to insufficient preparation and protection.
Conclusion
The expanded scope-of-practice policy both strengthens professional competence and creates role instability among clinical support nurses. Its sustainable implementation requires clear legal protection, standardized education and certification systems, appropriate compensation, and the active involvement of frontline nurses in policy development.

Development and evaluation of the Trauma-nursing Education and Skill Support program to enhance trauma nursing competencies: a quasi-experimental study: Tae Yeong Yang, Myung Jin Jang, Ki Ung Kim, Min So, Mi Na Choi, Eun Jung Lee, Jin Su Jo, Ji Yun Lee, Kwang Kyun Lim, Kyoung Mi Kim, Hae Jun Baek, Sun Ho Wang, Jin Oh Choi; J Korean Acad Nurs 2026;56(1):67-80. Published online February 24, 2026; DOI: https://doi.org/10.4040/jkan.25134

Abstract PDF ePub: Purpose
This study aimed to develop and evaluate the effectiveness of the Trauma-nursing Education and Skill Support (TESS) program based on the ADDIE model (Analysis, Design, Development, Implementation, Evaluation model). The program was designed to enhance trauma nurses’ clinical competencies, including trauma-related knowledge, self-efficacy, and problem-solving ability, through the integration of theoretical education and simulation-based practice.
Methods
A quasi-experimental study using a non-equivalent control group pretest–posttest design was conducted. Participants included 108 trauma nurses from regional trauma centers, military trauma centers, and emergency care facilities, who were assigned to an experimental group (n=52) or a control group (n=56). The TESS program consisted of a 2-day, 14-hour blended-learning course that included eight lecture sessions and four simulation-based practice stations. Data were collected at baseline, immediately after the intervention, and at 6 months using validated instruments measuring trauma-related knowledge, self-efficacy, and problem-solving ability. Two-way repeated-measures analysis of variance was used for data analysis.
Results
The experimental group demonstrated significant improvements in trauma-related knowledge, self-efficacy, and problem-solving ability compared with baseline (all p<.001). These improvements were sustained at 6 months, although trauma-related knowledge scores showed a slight decline compared with immediate posttest levels. Between-group analyses confirmed significant group-by-time interaction effects for all outcomes: trauma-related knowledge (η2=0.12, p<.001), self-efficacy (η2=0.09, p=.002), and problem-solving ability (η2=0.08, p=.003).
Conclusion
The TESS program effectively enhanced trauma nurses’ trauma-related knowledge, self-efficacy, and problem-solving ability, with effects sustained for up to 6 months. Incorporating blended learning and simulation-based training into standardized trauma nursing education may strengthen clinical competencies and ultimately contribute to improved patient outcomes.
