Comprehensive assessment of patients with chronic obstructive pulmonary disease by means of multicomponent ADO index and Charlson comorbidity index

Abstract

The purpose of this study was to investigate the ADO index, and index of comorbidity of Charlson in patients with chronic obstructive pulmonary disease (COPD). Materials and methods: 207 patients with chronic obstructive pulmonary disease (COPD) were observed. The investigated group was made by the patients having the long experience of smoking. Research of function of external breath was studied with multimodular installation of type «Master-Lab/Jaeger». Patients were determined the index ADO and of comorbidity of Charlson. Results: The index ADO increased with stage of COPD, minimum of level ADO was observed in patients with COPD 2 stage 2,23 ± 0,88, in patients with 3 stage COPD ADO was 5,05 ± 1,19, 4 stages of COPD 7,0 ± 1,0. The correlation coefficient between ADO index and and index of comorbidity Charlson was -0,71, p <0,005. The correlation coefficient between ADO and VC was -0,57, p <0,05, between ADO and ERV was -0,63, p <0,05.
