TL;DR
A poor Zubrod performance score was associated with a high mortality rate in all patient groups and survival was predicted by age, sex, current smoking habits, arterial carbon dioxide tension (PacO2) when breathing oxygen and oral steroid medication.
Abstract
On January 1, 1987, 560 patients (267 male) were registered as using long-term domiciliary oxygen therapy (LTO) in Sweden. The duration of LTO before this date varied between 10 days and 11 yrs. During a two-year follow-up 12 patients had their LTO withdrawn because they were no longer hypoxic. In 139 patients the arterial oxygen tension (PaO2) on breathing air was registered three times. In seventeen (12%) of these patients the PaO2 exceeded 7.5 kPa on all three control occasions. The two year actuarial survival in all patients was 57%. The two year actuarial survival was 77% in patients with kyphoscoliosis, 56% in patients with sequelae of tuberculosis, 54% in patients with chronic obstructive pulmonary disease (COPD) and 39% in patients with fibrosis. In COPD patients survival was predicted by age, sex, current smoking habits, arterial carbon dioxide tension (PacO2) when breathing oxygen and oral steroid medication. A poor Zubrod performance score was associated with a high mortality rate in all patient groups.
