Bibliometric Analysis of the Current Landscape of Chronic Obstructive Pulmonary Disease (COPD) Nursing Interventions and Research.

Purpose: Chronic Obstructive Pulmonary Disease (COPD) is a major global health issue, significantly impacting healthcare systems. Effective nursing interventions are crucial for improving patient outcomes and reducing hospitalizations. This study conducts a bibliometric analysis of nursing interventions and research in the management of COPD to identify key trends, contributors, and emerging research directions.

Material and methods: We analyzed 1390 articles published before 2024, sourced from the Web of Science Core Collection (SCI-Expanded). Using R Bibliometrix, VOSviewer, and CiteSpace, we assessed publication trends, identified influential authors and institutions, and mapped research hotspots and collaborations. The analysis included quantitative metrics such as citation counts and co-citation networks, as well as qualitative assessments of thematic evolution.

Results: The analysis revealed a significant increase in research output on COPD nursing interventions, particularly after 2001, with a peak in publications around 2021, likely due to the COVID-19 pandemic. The United States, the United Kingdom, and China were the top contributors, accounting for over 45% of the total publications. Key research hotspots included acute exacerbations, quality of life, evidence-based nursing, and pulmonary rehabilitation. The study highlighted a shift from symptom management to more holistic, patient-centered care models.

Conclusion: This study emphasizes the critical role of nursing interventions in managing COPD and reducing its global burden. The identified research trends and emerging topics offer valuable insights for future research, underscoring the need for innovation in nursing practices and interdisciplinary collaboration. These findings aim to inform the development of more effective COPD nursing strategies and enhance clinical practice.
