|Abstract:||Poor physical activity and high levels of frailty may be common in people with COPD using supplemental oxygen, but this has not been comprehensively assessed or followed up over time. The aim of this study was to assess and longitudinally follow up physical parameters of people with COPD who were supplemental oxygen users over a 2-year period. |
Eighteen participants [11 males, mean (SD) age 71.67 (9.93)] took part in a telephone-based assessment at baseline (T1) and follow-up (T2). The following variables were assessed; spirometry, self-perceived dyspnoea severity (eMRCD), health-related quality of life (HRQoL, EQ5D5L/EQVAS), sleep quality (Pittsburgh Sleep Quality Index), physical activity levels (Physical Activity Vital Sign), frailty (FiND questionnaire).
30% (n=12) of the initial cohort had died between baseline and 2-year follow-up. Spirometry [47.25 (16.92) at T1, 47.73 (15.78) at T2] and dyspnoea severity [median 3.00 at T1 and T2] remained stable. 27.8% (n=5) were frail at T1 compared to 66.7% (n=12) at T2. Sleep quality [8.17 (4.19) at T1 to 9.56 (5.03) at T2] and HRQoL decreased. At follow-up 89% of participants (n=16) did not meet physical activity recommendations.
Overall, although disease progression and dyspnoea remained stable within the two-year time period of this study, physical activity, HRQOL and sleep quality decreased. This study highlights areas, which should be targeted in long-term supplemental oxygen users.
