Abstract
Background and ObjectiveA mounting body of evidence suggests that lung function may deteriorate over time with the development of chronic lung diseases (CRDs). Pulmonary rehabilitation has been proved to improve exercise capacity and quality of life in individuals with CRDs. However, PR remains grossly underutilized all around the world. This study aimed to analyze the research trends on PR over the past 10 years.MethodsThe publications related to pulmonary rehabilitation in the Web of Science Core Collection (WoSCC) from 2011 to 2020 were searched. VOSviewer (1.6.15) and CiteSpace Software (5.5.R2) were used to analyze authors and co-cited authors, countries and institutions, journals and co-cited journals, co-cited references, and keywords.ResultsA total of 4,521 publications were retrieved between 2011 and 2020, and the number of annual publications on pulmonary rehabilitation has shown an overall upward trend in the past decade. The USA was the most productive country, the University of Toronto from Canada was both the first in publications and citations. Spruit MA was both the most productive author and the one with the highest number of co-citations. The first productive journal was the International Journal of Chronic Obstructive Pulmonary Disease, while the first co-cited journal was the American Journal of Respiratory and Critical Care Medicine. The hot keywords were grouped into three clusters, while “Asthma” and “Respiratory society statement” were determined as the frontier topics.ConclusionsThe present study successfully revealed the research status and development trends of pulmonary rehabilitation from 2011 to 2020 by using bibliometric analysis, which may help researchers explore and discover new research directions in the future.
