Low-income patients with hypoxaemia and chronic obstructive pulmonary disease, especially those receiving long-term oxygen therapy, experience a markedly impaired health-related quality of life (HRQL).
Dr CA Sant’Anna and colleagues of the Division of Respiratory Diseases, Heart Institute (InCor)/Hospital das Clinicas and the Division of General Internal Medicine, University of Sao Paulo School of Medicine, Brazil, carried out a study of 36 patients with chronic obstructive pulmonary disease (COPD) requiring long-term oxygen therapy.
Thirty three control subjects with COPD but no severe hypoxaemia, were enrolled as controls. The scores on the St George Respiratory Questionnaire (SGRQ) and the Medical Outcomes Study Short-Form 36-item questionnaire (SF-36) showed that severe impairment was present in the patients. Those on long-term oxygen therapy showed a trend towards worse scores on most dimensions of the SGRQ and SF-36.
