Development and evaluation of a question-answering chatbot to provide information for patients with coronary artery disease after percutaneous coronary intervention: Geunhee Lee, Yun Hee Shin; J Korean Acad Nurs 2025;55(2):153-164.

Abstract PDF ePub: Purpose
This study aimed to develop a question-answering chatbot that provides accurate and consistent answers to questions that may arise during the recovery process of patients with coronary artery disease after percutaneous coronary intervention, and to evaluate the chatbot.
Methods
The chatbot was developed through the stages of analysis, design, implementation, and evaluation. It was evaluated by five experts, and the user experience was evaluated by 27 patients who underwent percutaneous coronary intervention. Furthermore, chatbot utilization was analyzed based on user experience logs.
Results
The chatbot was constructed as a question-answering database that included three categories: coronary artery disease, percutaneous coronary intervention, and post-intervention management. The question-answering chatbot, referred to as the “Cardiovascular Strong” channel, has been launched and implemented. An expert evaluation of the chatbot revealed no usability issues or necessary modifications. The overall result of the user experience evaluation was 4.26 points. Based on the user experience log, the question-answer accuracy was 84.6%, and medications during post-intervention management were the most frequently searched topic, accounting for 110 cases (20.8%) out of a total of 528.
Conclusion
The chatbot that was developed to provide information via real-time answers to questions after the intervention can be easily accessed in clinical settings with no time or space constraints. It also will contribute to providing accurate disease-related information via the familiar KakaoTalk platform.

Keyword Network Analysis and Topic Modeling of News Articles Related to Artificial Intelligence and Nursing: Ha, Ju-Young , Park, Hyo-Jin; J Korean Acad Nurs 2023;53(1):55-68. Published online February 28, 2023; DOI: https://doi.org/10.4040/jkan.22117

Purpose
The purpose of this study was to identify the main keywords, network properties, and main topics of news articles related to artificial intelligence technology in the field of nursing.
Methods
After collecting artificial intelligence-and nursing-related news articles published between January 1, 1991, and July 24, 2022, keywords were extracted via preprocessing. A total of 3,267 articles were searched, and 2,996 were used for the final analysis. Text network analysis and topic modeling were performed using NetMiner 4.4.
Results
As a result of analyzing the frequency of appearance, the keywords used most frequently were education, medical robot, telecom, dementia, and the older adults living alone. Keyword network analysis revealed the following results: a density of 0.002, an average degree of 8.79, and an average distance of 2.43; the central keywords identified were ’education,’ ‘medical robot,’ and ‘fourth industry.’ Five topics were derived from news articles related to artificial intelligence and nursing: ‘Artificial intelligence nursing research and development in the health and medical field,’ ‘Education using artificial intelligence for children and youth care,’ ‘Nursing robot for older adults care,’ ‘Community care policy and artificial intelligence,’ and ‘Smart care technology in an aging society.’ Conclusion: The use of artificial intelligence may be helpful among the local community, older adult, children, and adolescents. In particular, health management using artificial intelligence is indispensable now that we are facing a super-aging society. In the future, studies on nursing intervention and development of nursing programs using artificial intelligence should be conducted.

Development of a Nursing Diagnosis System Using a Neural Network Model: Eun Ok Lee, Mi Soon Song, Myung Ki Kim, Hyeoun Ae Park; Journal of Nurses Academic Society 1996;26(2):281-289. Published online March 30, 2017; DOI: https://doi.org/10.4040/jnas.1996.26.2.281

Abstract PDF

Neural networks have recently attracted considerable attention in the field of classification and other areas. The purpose of this study was to demonstrate an experiment using back-propagation neural network model applied to nursing diagnosis. The network's structure has three layers; one input layer for representing signs and symptoms and one output layer for nursing diagnosis as well as one hidden layer. The first prototype of a nursing diagnosis systern for patients with stomach cancer was developed with 254 nodes for the input layer and 20 nodes for the output layer of 20 nursing diagnoses, by utilizing learning data set collected from 118 patients with stomach cancer. It showed a hitting ratio of .93 when the model was developed with 20,000 times of learning, 6 nodes of hidden layer, 0.5 of momentum and 0.5 of learning coefficient. The system was primarily designed to be an aid in the clinical reasoning process. It was intended to simplify the use of nursing diagnoses for clinical practitioners. In order to validate the developed model, a set of test data from 20 patients with stomach cancer was applied to the diagnosis system. The data for 17 patients were concurrent with the result produced from the nursing diagnosis system which shows the hitting ratio of 85%. Future research is needed to develop a system with more nursing diagnoses and an evaluation process, and to expand the system to be applicable to other groups of patients.
