CPAP not effective in sleep apnea in elderly population

"Our findings suggest that CPAP treatment is not as effective in patients over 80 years of age with OSA when compared to younger patients," said senior author David Gozal, MD, the Marie M. and Harry L. Smith Endowed Chair of Child Health at the MU School of Medicine. "We did not see any improvements in OSA-related symptoms, quality-of-life metrics, mood-related symptoms or blood pressure compared to the group that did not receive CPAP treatment."

Gozal said patients over 80 typically have a more sedentary lifestyle, and the presence of other disorders that may also affect the quality or quantity of sleep, but cannot be addressable with CPAP. He also cited other previous studies that suggest that patients older than 80 are less likely to adhere to CPAP therapy long-term.

"Considering the growing population of elderly patients that is being referred for sleep consultation, large clinical trials are urgently needed to try to solve key questions related to the use of CPAP in patients over the age of 75 or 80," Gozal said. "Those questions include: What type of elderly patient with OSA will benefit from CPAP? Is CPAP a cost-effective treatment for patients in this age group? And once CPAP treatment is initiated, should it last forever?"

In addition to Gozal, the study authors include several researchers from Spain, including co-lead author M.A. Martinez-Garcia, MD, PhD, section head of pneumology from Hospital Universitario and Politenico La Fe in Valencia.
