Purpose: The aim of this study was to identify the knowledge structure of nursing research on heart failure in Korea.
Methods: Fifty-two studies published in Korea and 41 published abroad by domestic researches from 1988 to 2019, were included. Meaningful morphemes from the abstracts were extracted and refined, and co-occurrence matrix was generated. Using Phython 3.7 for edge weight, degree centrality, closeness centrality, and betweenness centrality and Gephi 0.9.2 for visualization, 571 keywords were analyzed.
Results: The core keywords were “patient”, “heart failure”, “symptom”, “function”, “quality of life”, “self-care”, and “intervention”. The sociogram identified “patient”, “heart failure”, and “symptom” as the largest node, and the edge weight between the keywords was the highest. From 1988 to 2019, keywords such as “patient”, “heart failure”, and “symptom” ranked the highest. Especially, from 2016 to 2019, “quality of life”, “NYHA”, and “medication” ranked lower, but “cognition”, “health literacy”, “behavior”, “self-efficacy”, “man”, “woman”, and “age” newly appeared or ranked higher.
Conclusion: It is recommended that Korean heart failure nursing researchers conduct researches related to self-care for symptom management of heart failure patients, especially on nursing interventions. In addition, nursing researchers should conduct studies on the cognition and health literacy related to self-care of the elderly patients with heart failure.
