CPAP adherence after home sleep testing was equal to in-lab PSG

Lettieri et al prospectively observed 210 patients with obstructive sleep apnea, who were diagnosed & titrated in-lab or at home. Those who were diagnosed and titrated at home and managed through their primary care clinic had equivalent adherence with CPAP therapy (~70% of nights; ~4.5 hrs/night; regular use ~52%) to those diagnosed and titrated in-lab and followed by sleep experts. CHEST 2011;139:849-854.
