Background:
Many factors contribute to continuous positive airway pressure (CPAP) nonadherence, affecting health care burden. The original CPAP-SAVER study enrolled 66 CPAP-naive participants and showed high 1-month adherence and significantly higher apnea beliefs and CPAP attitude for the intervention group.
Purpose And Methods:
Thirty-three participants from the original CPAP-SAVER study were recruited for a 3-year follow-up to determine adherence, examine the intervention effect, and identify adherence-associated factors.
Results:
Adherence rates dropped to 54.5% at 3 years, with a significant decrease in CPAP use hours (t = -2.37, p = .024) and nights (t = -4.05, p < .001). Group differences in beliefs and attitude were not sustained; however, beliefs (r = 0.57) and attitude (r = 0.44) were significant factors associated with adherence. Life satisfaction was significantly higher at present compared with before wearing CPAP (t = 5.17, p < .001).
Implications For Practice:
The authors recommend intervention with a focus on apnea beliefs, CPAP attitude, and long-term support to promote CPAP adherence. Focus on CPAP attitude and beliefs and enhanced support early in the obstructive sleep apnea (OSA) treatment trajectory may promote long-term adherence and subsequently reduce the health care burden of OSA disease.

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
