Background Hospital admissions are important contributors to the overall burden of chronic obstructive pulmonary disease (COPD). Understanding the patterns and causes of hospital admissions will help to identify targets for preventive interventions. This study aimed to determine the five-year all-cause hospital admission trajectories of patients with COPD following their first-ever exacerbation-related hospitalization.Methods Patients with COPD were identified from the Danish national registries. Patients experiencing their first-ever exacerbation-related hospitalization, defined as the index event, between 2000 and 2014 were included. All-cause hospital admissions were examined during a subsequent five-year follow-up period, and categorized using the International Classification of Diseases, 10th revision (ICD-10).Results In total, 82 964 patients with COPD were included. The average age was 72 (sd 10) years and 488 and 65=6 months prior to the index event. In total, 337 066 all-cause hospital admissions were identified, resulting in a five-year admission rate of 82respiratory causes (59, amongst which cardiac events were most common (19.Conclusion Hospital admissions following a first exacerbation-related hospitalization are common, non-respiratory events constitute the majority of admissions. Besides the respiratory causes, treatment targeting the non-respiratory causes of hospital admission should be considered to effectively decrease the burden of hospitalization in COPD.FootnotesThis manuscript has recently been accepted for publication in the ERJ Open Research.
