An Analysis of Interviews between Nurse Educators and Newly Graduated Nurses Regarding Adaptation to Clinical Nursing Practice: Text Network Analysis and Topic Modeling
Hyowon Jo, Hyunjung Ko, Seulki Jeong, Minyoung Park, Seul Lee, Seok Hee Jeong
J Korean Acad Nurs Adm 2026;32(2):123-135.   Published online March 31, 2026
DOI: https://doi.org/10.11111/jkana.2025.0059
Purpose
This study identified themes associated with the clinical adaptation of newly graduated nurses. Methods: We collected 522 interview journals from newly graduated nurses and nurse educators at a tertiary hospital between January 2021 and December 2023. After excluding incomplete data, 407 “promoting enjoyment” entries and 426 “presenting challenges” entries were analyzed using network analysis and topic modeling in NetMiner 4.5.1. Results: Topic modeling identified four themes in each category. For promoting enjoyment, the themes were: “Upon completing my designated responsibilities, I depart from the workplace,” “On my days off, I enjoy indulging in my favorite activities,” “Being recognized by my colleagues makes me feel like I’m contributing my part to the team,” and “The condition of my patient has improved.” For presenting challenges, the themes were: “The numerous responsibilities I must handle make it difficult to complete everything within the designated time frame,” “I struggle with both my tasks and relationships with colleagues,” “I’m anxious about caring for patients on my own,” and “Irregular shift patterns and occupational distress significantly impair my sleep quality.” Conclusion: Educational methodologies need to be developed to facilitate the clinical adaptation of newly graduated nurses. These findings can inform the Ministry of Health and Welfare’s nurse educator policy and future nursing workforce strategies.

J Korean Acad Nurs Adm 2024;30(5):529-542.   Published online December 31, 2024
DOI: https://doi.org/10.11111/jkana.2024.30.5.529
Purpose
This study aimed to explore customer perspectives of nursing services in tertiary hospitals.
Methods
The data comprised mobile Voice Of Customer (VOC) data related to “nursing” or “nurses” generated from June 25, 2019, to December 31, 2022, in a tertiary hospital. A total of 44,727 VOC data points were collected, of which 4,040 were selected for the final analysis. Text network analysis and topic modeling were conducted using NetMiner 4.5.1.
Results
Topic modeling identified five topics for positive aspects and four topics for areas requiring improvement. The positive aspects were: 1) sincere nursing care; 2) rapid response from professional medical staff; 3) teamwork for delivering customer-centric services; 4) provision and coordination of system-based healthcare services; and 5) customer-focused responsiveness. The areas requiring improvement were: 1) demand for skilled nursing care tailored to customer expectations; 2) demand for enhanced communication and reduced mechanical responses; 3) demand for appropriate handling of diverse situations; and 4) demand for overall improvements to the healthcare system, including reservation systems.
Conclusion
These results may be used to enhance customer and patient experiences in tertiary hospitals and are necessary for utilization from a hospital management perspective.
