“…Our patients presented less impaired lung function which can explain this difference. In COPD patients, pulse oximetry at rest was correlated with walking speed in keeping with previous result 24 .…”

“…Although the level of association was not explained in the reviewed studies [26,[31][32][33][34] the association of GOLD stage in grading the degree of COPD was correlated with that of BODE index score, its components (FEV1% predicted, dyspnea score and 6MWDT score) was supported with the present study. The correlation of GOLD stage in grading the severity of the disease was in line with our study as statistically evidenced with BODE index score (R=0.475, P-value=0.011) [29], with 6MWDT score (R=0.358, P-value<0.003) [37] and (R=0.524, P-value=0.006) [38], with dyspnea score (R=0.360, P-value=0.06) [39] with BMI score (R=0.296, P-value=0.126) [29].…”

Background: Chronic obstructive pulmonary disease (COPD) is a preventable and treatable disease characterized by partially reversible airflow limitation. BODE index is amultidimensional tool stands as pneumonic composing the four individual variables {B-the body mass index (BMI), O-the degree of airway obstruction (post-bronchodilator FEV1% predicted), D-Dyspnea scale and E-exercise capacity measured by 6-minute walk distance test (6MWDT)}; giving the total points of 10; divided into four quartiles. It is used to diagnose, grade the severity, evaluate systemic comorbidities, evaluate the response to intervention and predict the mortality due to the disease. Purpose: To assess the severity of COPD by using BODE index and its individual variables, and GOLD stage; correlate their values to each other and determine their validity in stratifying the severity of COPD. Patients and methods: A hospital based cross-sectional study was conducted among a sampled 80 consecutive COPD patients visiting chest clinic of Jimma University Medical Center (JUMC) located at Jimma town, South west Ethiopia; from May 18 to August 18, 2017 G.C; and the measurement of all individual variables of BODE index were performed according to the American Thoracic Society (ATS), their results were entered into EPI data (3.1) and exported to SPSS (20) for further analysis. Chi square (X 2) test, Spearman correlation, kappa measure of agreement, receiver operator characteristic (ROC) and area under curve (AUC) was applied to determine the correlation and validity of variables/tools in grading the severity of the disease. Results: 80 COPD patients were enrolled in the study, Mean of age (55.1±13.66), BMI(19.98±3.43), 6MWDT (283±84.5), BODE index point (6.17±2.55), FEV1% predicted (42.5±15.6) and Dyspnea scale (2.2±0.7) were achieved. Majority of COPD patients were belonged to quartile IV, relatively increased through the stages if classification was made by BODE index and its components (FEV1% predicted and 6MWDT) but was higher among stage 3/severe if it was based on GOLD stage and dyspnea score. All variables used to grade COPD were positively correlated with each other except with BMI score (inversely correlated). The validity of the variables/tools used in grading severity of the disease was ranked as BODE index, 6MWDT, FEV1%, GOLD stage and dyspnea score in descending order while BMI score had the least/poor validity to predict the aim of the study based on specific results of their sensitivity, specificity, AUC with 95% CI and p-value. Conclusion: All variables except BMI score were valid to predict severity of COPD.

“…Most previous studies focused on the impact of the six-minute walk test on gas exchange (37,38). It was demonstrated that six-minute walk distance is correlated with baseline O 2 saturation before and after testing (37). In a study suggesting that the six-minute walk test is a good determinant of prognosis in COPD patients, it was concluded that short walking distance and increased variability of O 2 saturation are independent and significant determinants of mortality (38).…”
