Among patients with mild obstructive sleep apnea (OSA), quality of life is improved at three months for those receiving continuous positive airway pressure (CPAP) therapy plus standard care compared with standard care alone, according to a study published online in The Lancet Respiratory Medicine.

Alison J. Wimms, Ph.D., from University of Sydney, and colleagues randomly assigned 233 participants with mild OSA to receive either CPAP therapy plus standard care (sleep hygiene counseling) or standard care alone.

Based on the 90 percent of patients who completed the trial, the researchers found that the vitality score significantly increased with a treatment effect of a mean of 10.0 points after three months of CPAP versus standard care alone. Using a more conservative estimate, the analysis of covariance last-observation-carried-forward analysis, the vitality score also significantly increased, with a treatment effect of a mean of 7.5 points after three months of CPAP versus standard care alone.

"These results highlight the need for health care professionals and providers to consider treatment for patients with mild obstructive sleep apnea," the authors write.
