This case report aims to emphasize the importance of a differential diagnosis when patients complain about pain. Although pain is one of cancer patients’ most common physical symptoms, not all pain is due to cancer itself. Hence, nurses need to pay more attention to assessing pain accurately and making differential diagnoses that consider all possible causes. This case report concerns two patients diagnosed with Non-Small Cell Lung Cancer (NSCLC). One patient complained of localized right anterior chest pain triggered suddenly four days prior. Bone scan imaging taken four months prior showed a bone metastasis of the right anterior 4th rib correlating with the location of his pain. The second patient complained of right chest pain with cough, sputum, and dyspnea. Given his history of cancer that obstructed the right bronchus, causing right pneumothorax four years ago, structural and inflammatory causes should have been considered. In these two cases, chest pain was attributed to different factors requiring different treatment and nursing plans. To assess pain properly, nurses have to thoroughly examine patients through medical history and physical examination. Electronic medical records and recent test results should be obtained ‘as well’.

Purpose: The significance of the healthcare industry has grown exponentially in recent years due to the impact of the fourth industrial revolution and the ongoing pandemic. Accordingly, this study aimed to examine domestic healthcare-related patents comprehensively. Big data analysis was used to present the trend and status of patents filed in nursing. Methods: The descriptive review was conducted based on Grant and Booth’s descriptive review framework. Patents related to nursing was searched in the Korea Intellectual Property Rights Information Service between January 2016 to December 2020. Data analysis included descriptive statistics, phi-coefficient for correlations, and network analysis using the R program (version 4.2.2). Results: Among 37,824 patents initially searched, 1,574 were selected based on the inclusion criteria. Nursing-related patents did not specify subjects, and many patents (41.4%) were related to treatment in the healthcare delivery phase. Furthermore, most patents (56.1%) were designed to increase effectiveness. The words frequently used in the titles of nursing-related patents were, in order, “artificial intelligence,” “health management,” and “medical information,” and the main terms with high connection centrality were “artificial intelligence” and “therapeutic system.” Conclusion The industrialization of nursing is the best solution for developing the healthcare industry and national health promotion. Collaborations in education, research, and policy will help the nursing industry become a healthcare industry of the future. This will prime the enhancement of the national economy and public health.
