A very common questionnaire, used to evaluate the health status of Chronic Obstructive Pulmonary Disease (COPD) patients, COPD assessment test (CAT), was applied to finding correlations between the items of CAT and other tests used in the same category of COPD patients. A sample of 56 male COPD patients, aged between 51 and 74 years, mean 63.86 (�5.55), half of them receiving long-term oxygen therapy, using transparent, hypoallergenic plastic masks or nasal cannulas, answered to CAT mostly choosing single items, statistically significant correlated with the Hospital Anxiety and Depression Scale scores (HADs), like walking up hills and stairs (r = 0.412, p[ 0.01), doing activities at home (r = 0.329, p[ 0.01), confidence leaving my home (r = 0.409, p[ 0.001), sleep (r = 0.277, p[ 0.01), and energy (r = 0.387, p[ 0.01), but CAT item walking up hills and stairs correlated better to 6 min walking distance (6MWD) (r = -0.581, p[ 0.01). The most significant correlations were found between 3 items of CAT as walking up hills and stairs, limitations doing activities at home and confidence leaving home in a most powerful and depression scores and 6MWD.
Introduction. Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality throughout the world. At present, the pharmacological therapy is not enough for a patient with COPD in regard to heath status and exercise tolerance. It requires additional therapies aimed to improve the quality of life, delay the lung function decline, increase exercise capacity, and reduce the respiratory symptoms and the number of exacerbations. Pulmonary rehabilitation program (PRP) has been shown to improve respiratory muscle, to optimize functional, psychosocial, behavioral and nutritional status. The aim of the present study was to asses the impact of PRP on COPD patients, focusing on the clinical benefits of PRP, which may further provide to the patients a good support for change. Material and method. Sixty-seven patients with clinically stable COPD were enrolled in this prospective study, consisting in a 6-weeks of PRP. There were recorded demographic data, smoking and medical history, and abnormal findings at the physical examination. All patients completed CAT (COPD Assessment Test) questionnaire and dyspnea on Borg scale, they performed spirometry, and six minutes walking test (6MWT), before and after the completion of the rehabilitation program. Results and Discussions. After the 6-week period of PRP, a large proportion of patients presented higher values of spirometric parameters, although the change was no statistically significant. The impact of COPD on the patient’s health was significantly improved, 58.2% of patients registered < 10 points of CAT questionnaire after PRP (p<0.05). 75% of patients reported a 0-5 points of dyspnea on Borg scale comparing with 29% before the PRP (p=0.0147), and 56% a 0-5 points of fatigue while only 25% of patients had the same score before the rehabilitation programme (p=0,022). Only 8 patients (11.94% vs 31.34%, p<0.05) reported a SaO2 lower than 90% after the PRP. The 6MWD was longer than 250m at the end of the 6-weeks of PRP for 38 patients (56.7% vs 22.38%, p<0.05). Conclusions. The present study showed that a PRP added to pharmacological treatment had a beneficial role of increasing the patient’ health status and exercise tolerance for COPD patients.
