ABSTRACT
Improving quality of life, functional capacity and dyspnea in lung diseases is the main goal in pulmonary rehabilitation programs. St George’s questionnaire (SGRQ), has demonstrated reliability in patients with air flow limitation.
Exercise tolerance is evaluated with the 6 minute walk test and the incremental Shuttle test (IST); it correlates with oxygen consumption VO2 and indicates aerobic capacity.
Objective: The goal of this study is to evaluate the correlation between SGRQ and IST in COPD and interstitial lung diseases (ILD).
Material and methods: Retrospective, observational, transversal study. We reviewed first time admissions into the Pulmonary Rehabilitation Program of patients with COPD and ILD by means of spirometry, SGRQ and IST.
Results: We included 95 patients, 58 with ILD, and with 37 COPD. We found a positive correlation in ILD (IST) and the SGRQ in the activity items, impact disease and the total of the questionnaire; also with FVC and FEV1 in absolute values and percentage.
In COPD patients we found a better correlation between IST and the SGRQ but not with spirometry.
Conclusion: Patients with interstitial lung diseases and poor function tests demonstrate a reduced exercise capacity and poor quality of life (QOL).
Patients with COPD and poor QOL showed no correlation with the results of lung function tests.
