Purpose: This study aimed to explore research trends in nursing organizational culture or climate in South Korea using topic modeling.Methods: A total of 206 journal articles published in South Korea from 2010 to 2023 were identified as relevant. Semantic morphemes of the English abstracts were refined, and a co-occurrence matrix with 145 keywords was generated. Using the NetMiner program, the characteristics of text networks, degree centrality, semantic structure, and latent Dirichlet allocation (LDA) topic modeling were analyzed.Results: The top 30 keywords with the highest degree centrality, considered critical core keywords, included “patient safety culture,” “organizational commitment,” “innovation culture,” “relational culture,” “job satisfaction,” “infection control,” “workplace bullying,” and “turnover intention” alongside “RNs,” “organizational culture,” and “hospital.” The critical core keywords varied over different time periods. Four main topics were identified: (a) organizational culture and registered nurse (RN) job satisfaction, (b) workplace bullying and organizational culture, (c) organizational culture for infection control and patient safety, and (d) organizational culture for person-centered care and teamwork.Conclusion: Nursing organizational culture was approached as either a generic culture or a focused culture related to specific performance or outcomes, mainly patient safety, person-centered care, or teamwork. The disadvantages of a hierarchy-oriented culture were evident, indicating a need for nurse leaders to initiate changes. Future research should expand to include long-term care facilities, intervention studies aimed at changing organizational culture, studies utilizing qualitative methods or longitudinal approaches, and the development of measures for nursing organizational culture.
