In secondary analysis of patients with chronic obstructive pulmonary disease (COPD), readiness, confidence, and importance to use long-term oxygen therapy (LTOT) at initiation were significantly associated with adherence. Researchers conducted a secondary analysis of data from 359 COPD participants assigned to oxygen in the Long-term Oxygen Treatment Trial. They were prescribed continuous (n=214) or intermittent (n=145) oxygen based on desaturation patterns at study entry. At the time of initial prescription, participants rated their perceived readiness, confidence, and importance to use oxygen on a 0-10 scale. Among the findings:
- Participant readiness, confidence, and importance at the time of oxygen initiation were associated with high short- and medium-term adherence.
- Characteristics associated with high adherence differed initially and over time.
- Adherence characteristics differed in continuous vs intermittent oxygen groups.
- In both groups, high adherence in the medium-term was associated with high adherence in the long-term.
