Differences in Survival of Patients With COPD According to the New GesEPOC 2021 Classification of Phenotypes.

Introduction: Chronic obstructive pulmonary disease (COPD) is a respiratory pathology with high prevalence, morbidity and mortality. The Spanish COPD guideline (GesEPOC) recommends individualizing treatment according to phenotypes. The phenotype classification was updated in 2021.

Influence of Comorbidities on the Survival of COPD Patients According to Phenotypes.

Background: Chronic obstructive pulmonary disease (COPD) usually occurs alongside other conditions. Few studies on comorbidities have taken into account the phenotypes of COPD patients. The objective of this study is to evaluate the prevalence of comorbidities included in the Charlson index and their influence on the survival of patients with COPD, taking phenotypes into account.

COPD phenotypes: differences in survival.

Background: The aim of the study was to analyze the characteristics and survival of a group of patients with COPD according to their clinical phenotype.

Patients And Methods: The study population was selected from patients undergoing scheduled spirometry between January 1, 2011 and June 30, 2011 at the respiratory function laboratory of a teaching hospital and comprised those with a previous and confirmed diagnosis of COPD and forced expiratory volume in the first second (FEV) of <70%. The patients selected were classified into 4 groups: positive bronchodilator response, non-exacerbator, exacerbator with emphysema, and exacerbator with chronic bronchitis.
