Objective: To evaluate the health-related quality of life of patients with chronic obstructive pulmonary disease receiving long-term oxygen therapy (LTOT) at home through oxygen cylinders and compare these results with those obtained six months after the transition from oxygen cylinders to oxygen concentrators. Methods: A total of 45 patients were evaluated. Of those, 24 had chronic hypoxemia and 21 presented no evidence of hypoxemia. The patients with chronic hypoxemia had been regularly receiving LTOT for at least the last six months and were evaluated at baseline, while using cylinders, and six months after the transition from cylinders to concentrators. The non-hypoxemic patients were evaluated at the same time points as were the hypoxemic patients. In order to evaluate quality of life, a version of the Saint George's Respiratory Questionnaire (SGRQ), translated and validated for use in Brazil, was administered. Results: At baseline, quality of life, as evaluated using the total score and the symptom and impact domain scores of the SGRQ, was more impaired in the hypoxemic patients than in the non-hypoxemic patients. After six months of using the concentrators, the hypoxemic patients presented a significant improvement in the quality of life, and, at that time, no difference was found between the patients with and without hypoxemia. Conclusion: Our findings show that quality of life is impaired in patients with chronic obstructive pulmonary disease and chronic hypoxemia, that their quality of life can be improved through regular use of LTOT, and that the oxygen delivery system has an influence on this improvement.Keywords: Pulmonary disease, Chronic obstructive; Anoxemia; Oxygen inhalation therapy; Quality of life. ResumoObjetivo: Avaliar a qualidade de vida relacionada à saúde de pacientes com doença obstrutiva crônica das vias aéreas recebendo oxigenoretapia domiciliar prolongada (ODP) por meio de cilindros de oxigênio e comparar estes resultados com os obtidos após seis meses de modificação do sistema de fornecimento para concentradores de oxigênio. Métodos: Um total de 45 pacientes, 24 com hipoxemia crônica e 21 sem evidências de hipoxemia, foram avaliados. Os pacientes com hipoxemia crônica estavam recebendo ODP regularmente durante pelo menos os últimos seis meses e foram avaliados no momento basal, em uso de cilindro, e após seis meses de transição para concentradores. Os pacientes não hipoxêmicos foram avaliados no mesmo intervalo de tempo que os pacientes hipoxêmicos. Para avaliar a qualidade de vida foi utilizada a versão validada para língua portuguesa (Brasil) do Questionário Respiratório Saint George (Saint George's Respiratory Questionnaire -SGRQ). Resultados: No momento inicial, os pacientes hipoxêmicos apresentaram maior comprometimento da qualidade de vida, avaliada pelo escore total e pelos escores dos domínios sintomas e impacto do SGRQ, que os pacientes não hipoxêmicos. Após seis meses, houve melhora significativa da qualidade de vida dos pacientes hipoxêmicos e, neste momento, não...

“…In a recent study, this questionnaire did not discriminate between patients with different levels of hypoxia in contrast to a disease-specific measure whose scores were correlated with arterial oxygen tension Pa,O 2 [12]. It is possible that the use of an oxygen concentrator for the provision of LTOT might reduce a patients' quality of life by causing problems, such as restricted mobility, noise disturbance, and sore nose or ears from the use of nasal cannulae [14].The aim of the present study was to assess the effect of LTOT on quality of life in patients with hypoxaemia and COPD using a disease-specific measure of life quality, the St George's Respiratory Questionnaire (SGRQ) [15], as well as the SIP. Quality of life scores for the patients using LTOT were compared with scores for a control group of patients with severe COPD but without severe hypoxaemia, who therefore did not require LTOT.…”

ABSTRACT: Long-term oxygen therapy (LTOT) improves survival in patients with hypoxaemic chronic obstructive pulmonary disease (COPD), but previous studies using general health measures have shown no effect on quality of life (QoL). In this study, the effect of LTOT on QoL was assessed using a disease-specific health measure, the St George's Respiratory Questionnaire (SGRQ). Twenty three hypoxaemic COPD patients (15 females and 8 males) were studied before and after starting LTOT: median age 71 (range 47-82) yrs, mean ( The LTOT group had higher SGRQ total scores than controls (p<0.05) at all visits, implying lower QoL. Repeated measures analysis of variance showed no effect of LTOT on QoL over 6 months (F=0.43, p=0.79).In this study we detected no change in quality of life using a disease-specific health measure in patients with severe chronic obstructive pulmonary disease using an oxygen concentrator to provide long-term oxygen therapy. Eur Respir J., 1996Respir J., , 9, 2335Respir J., -2339 Long-term oxygen therapy (LTOT) is a well-established treatment for patients with chronic obstructive pulmonary disease (COPD) and severe hypoxaemia. Two large, randomized studies, the British Medical Research Council (MRC) study and the Nocturnal Oxygen Therapy Trial (NOTT) study from the USA, published in the early 1980s, established that LTOT for at least 15 h·day -1 can reduce mortality in these patients [1, 2]. Other studies have shown physiological benefits of LTOT, including reduction of pulmonary hypertension and secondary polycythaemia [3][4][5][6], and improvements in neuropsychological function [7,8].In addition to having a poor prognosis, patients with severe hypoxaemia and COPD suffer considerable functional disability. Several studies have shown that quality of life is impaired in patients with COPD and hypoxaemia [9][10][11]. Furthermore, in patients with moderateto-severe hypoxaemia, the quality of life score is related to the degree of hypoxaemia when measured using a disease-specific questionnaire [12]. However, the effect of LTOT on quality of life has not been clearly established. In an ancillary study to the NOTT study, there was no improvement in quality of life over 6 months in patients with hypoxic COPD treated with oxygen compared to age-matched controls without COPD [8]. This study used a general health questionnaire, the Sickness Impact Profile (SIP) [13]. In a recent study, this questionnaire did not discriminate between patients with different levels of hypoxia in contrast to a disease-specific measure whose scores were correlated with arterial oxygen tension Pa,O 2 [12]. It is possible that the use of an oxygen concentrator for the provisio...

“…Several factors can be associated with muscle wasting in individuals with COPD, such as nutritional alterations, use of corticosteroids and disuse [2,3]. The pulmonary and systemic manifestations of COPD together result in a reduction of exercise capacity and development of symptoms commonly reported by patients, such as dyspnea and fatigue [4]. These symptoms are associated with a reduction in the level of physical activity in daily life and, consequently, further deterioration of exercise capacity [3,5,6].…”
