Research Trends and Hotspots in Childhood Interstitial Lung Disease Over 40 Years: A Bibliometric Analysis

Abstract

This study examines the research trends and hotspots in the field of Childhood Interstitial Lung Disease (chILD) over the past four decades. The research was based on 1,123 articles published between 1984 and 2023, with the United States ranking first with 351 publications (31.3%). The study also identified three main research trends: classification, diagnosis, and management of chILD, genetic studies of chILD, and primary diseases associated with chILD. Keywords such as 'polymyositis’, ‘management', 'features', 'efficacy', and ‘mutations' reflected recent research hotspots. Johns Hopkins University was the leader in overall impact, with 44 scholarly works and a cumulative citation count of 2,732. The American Journal of Respiratory and Critical Care Medicine ranked sixth in publication volume but second in total citation counts and average citations per paper. Future research may focus on clinical features, disease management, gene mutations, and polymyositis accompanied by chILD.
