Avaliação de comorbidades e mortalidade em indivíduos com doença pulmonar obstrutiva crônica

Abstract

Chronic Obstructive Pulmonary Disease (COPD) is a chronic and often progressive respiratory condition that can be prevented and treated. It is characterized by airflow limitation and is often associated with other comorbidities. It is one of the few chronic diseases that has been increasing both prevalence and mortality, becoming a major public health problem with considerable morbidity and mortality. The aim of this study was to evaluate the health status of individuals with chronic obstructive pulmonary disease and to relate and identify predictors of mortality in patients in a pulmonary rehabilitation program. This is an observational, longitudinal, prospective study conducted at the pulmonary rehabilitation unit of a University Hospital in the central region of Rio Grande do Sul, from October 2018 to July 2019. The research sample consisted of: 43 patients with chronic obstructive pulmonary disease of both sexes. Patients were evaluated for psychosocial aspects, diagnoses, body composition, hematological analyzes, sensation of dyspnea through Modified Medical ResearchCouncil (mMRC), the impact of symptoms on quality of life was verified through the COPD Assessment Test (CAT) questionnaire and the Age-corrected Charlson Comorbidity Index (ICC-I) was used to determine the degree of comorbidity. There was a correlation between ICC-I in relation to gender, monocytes and eosinophils, correlations between BMI and FEV1 / FVC ratio, as well as between mMRC and FEV1. Also, we found that monocyte count was associated with dyspnea, in addition to the association between decreased circulating hemoglobin and decreased survival rate.
