Objective To explore the clinical phenotype of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) by cluster analysis and provide a basis for individualized treatment.Methods A total of 515 patients with acute exacerbation of COPD admitted to this department from January 2014 to December 2016 were enrolled. The age, duration, smoking index, number of hospitalizations in the past 1 year, hospitalization days, treatment costs and other information were collected for cluster analysis.Results The patients were divided into three categories of phenotype: " mild-glucocorticoid resistance-antibiotic dependent”," mild-glucocorticoid sensitive”, and " serious complication”. The patients with the first two phenotypes had a milder condition and lower hospitalization costs. There were differences in the time and cumulative dose of glucocorticoids in different pathways, antibiotic use time and usage rate. The third phenotype was the most serious, with the highest cost of hospitalization, and may merge or co-exist with other diseases such as cardiovascular disease and digestive tract disease.Conclusion Cluster analysis may identify different phenotypes of acute exacerbation of COPD to provide a reference for clinical individualized treatment.
