Abstract:
This study was performed in chronic obstructive pulmonary disease (COPD) patients to compare the SF-36 questionnaire with pulmonary function tests and non-functional parameters. Fourty-five COPD patients diagnosed according to GOLD 2004 criteria were included in the study. The stable patients were evaluated by spirometry, static lung volumes, diffusion capacity, 6 MWD, BORG scale, MMRC dyspnea measurement and SF-36 life questionnaire performed on the same day. The mean age of the patients was 66 +/- 10 years and the female/male ratio was 4/41. The mean FEV1/FVC ratio was 0.49 (moderate COPD n = 18, severe COPD n = 27). The RV/TLC ratio was 0.52. Walking distance was less than normal, with a mean of 375 +/- 119 m. All the SF-36 scale except pain index are low compared to normal. General health perceptions, physical functioning, role physical, role emotional, social functioning, energy and mental health index are as follows: 47 +/- 24, 50 +/- 30, 35 +/- 38, 49 +/- 37, 63 +/- 33, 49 +/- 20, 59 +/- 20, respectively. When the general health scale compared with FVC and FEV1 revealed moderate correlation was found (r = 0.56, r = 0.55, respectively). Physical functioning compared with FVC, FEV1, RV/TLC and IC revealed moderate correlation (r = 0.62, r = 0.67, r = -0.54, r = 0.65, respectively). General health and physical functioning scales correlated with the non-functional parameters (MMRC, 6 MWD) (r = -0.51, r = 0.53, r = -0.61, r = 0.64 respectively). The SF-36 general quality of life questionnaire is a useful measurement instrument for the evaluation of therapeutic efficiency and follow up of COPD patients.
